REVIEWED AND APPROVED BY: First Vehicle Services 3009 Pamplico Highway Florence, SC 29505 Memo February 23, 2021 Ms. Takiyah A Douse Director Central Services Director Augusta GA 30906 Dear Ms. Douse This is the time of year most of our customers are working on their budgets and planning for the upcoming budget year. With that understanding we would request Augusta Richmond GA consider the contract extension option in the contract outlined in Section One Article One below. Therefore, by mutual agreement FVS would like to extend the contract from January 1, 2022 through December 31, 2022. In addition, Section 13 of the contract allows for a budget increase based on the CPI. The Current CPI is 3.4% but we could accept a 1.5% increase on labor, parts, and overheads to help bring us back up to budget and help Augusta with their budget. As you know we ran $23,000 over budget in 2020. We are not requesting any increase to the fees. This increase would raise the current budget by $36,143 for a total of $2,963,946 annually. First Vehicle Services 3009 Pamplico Highway Florence, SC 29505 Memo Thanks for taking this option in consideration. If you have any questions, I can be reached any time at 843-319-3157 Sincerely, Steve Breeden Region Vice President First Vehicle Services Administrative Services Committee Meeting 4/13/2021 1:05 PM 2021 - Fleet Maintenance Contract Extension Department:Central Services Department - Fleet Management Presenter:Ron Crowden Caption:Motion to approve a one year extension of the Augusta Fleet Maintenance Contract for 2022 at a cost of $2,963,946.00 to First Vehicle Services. (REF - RFP 19-225) Background:Augusta entered into a 3 year fleet maintenance contract for vehicles and equipment, excluding Environmental Services, Fire and Transit Departments. This contract supports more than 56 divisions with over 2,400 vehicles and equipment. The increase in cost from 2021 to the request for extension is $36,143.00. First Vehicle Services has provided fleet maintenance services to Augusta since 2005, as a result of various requests for proposals being advertised. Per our current fleet maintenance contract, the 3 year contract was approved by Commission on 1/25/2019. The item has two one year extensions which may be granted by mutual agreement of both parties.

THIS AGREEMENT, made and entered into this ____ day of ____________, 2021 by and between ____________ hereinafter referred to as “BORROWER,” and AUGUSTA HOUSING & COMMUNITY DEVLOPMENT having its principal office at 510 Fenwick, Augusta, Georgia 30901, hereinafter referred to as “LENDER.” WHEREAS, on ___________________, the Lender agreed to provide to the Borrower financial assistance to be used in pursuit of the purchase of certain real property hereafter described: _Map Parcel #___ and ___________________________________. WHEREAS, a percentage of said financial assistance was provided in the form of a Forgivable Loan, hereinafter referred to as a “LOAN,” with said Loan being in the amount of Twenty-Five thousand dollars 00/100 ($25,000.00) subject to the condition that the Borrower executes this Agreement. WHEREAS, the Forgiveness Loan is funded by the U.S. Department of Housing and Urban Development (“hereafter HUD”) via the HOME Investment Partnership Program (hereafter “HOME Program”), and restrictions apply to the Borrower when participating in the City of Augusta’s Forgiveness Loan Program. NOW THEREFORE, in consideration of the said Loan and in accordance with the provisions of State of Georgia Statues, the parties do hereby agree as follows: The Borrower covenants and agrees with the Lender to adhere to the following HOME Program Restrictions imposed on them for the federal assistance provided: Affordability Period You must comply with the HOME Program’s period of affordability. The period of affordability for the home will be 10 years, based on the amount of the direct subsidy to the HOMEBUYER. During this 10 year period, the HOMEBUYER must maintain the home as his/her principal place of residence at all times. During this time the recapture restriction is effective and requires all HOME funds that were provided for the purchase of the home to be repaid to the City, including principal, HOME Program – Homebuyer Written Agreement Page 2 of 5 interest, late fees, and other charges, if you do not occupy the property as your principal residence or if you sell or transfer the property. Maximum Sales Price The property may not have a purchase price for the type of single family housing that exceeds 95% of the median purchase price for the area. It has been verified that the purchase price of the housing does not exceed 95 percent (95%) of the median purchase price of homes for the area, as set forth in 24 CFR Part 92.254(a). The maximum purchase price is as follows for the Augusta Richmond County GA: Unit # FHA Limits Pre-Economic Stimulus Act- 2020 Existing Homes New Homes 1 Unit $ 157,000 $ 238,000 2 Unit $ 201,000 $ 304,000 3 Unit $ 243,000 $ 368,000 4 Unit $ 301,000 $ 456,000 Unadjusted Median Value $ 164,900 $ 250,000 Appraised property value The AWARDEE certifies that a certified property appraiser has appraised the property that is the subject of this AGREEMENT at a value of $________. Principal residence requirement This agreement shall remain in force throughout the affordability period as long as the home remains the principal residence of the HOMEBUYER. Should the HOMEBUYER not maintain the home as his/her principal residence, or rent or sell the residence to another party, the HOMEBUYER will be in breach of this agreement and will be required to repay the amount awarded, as of the day the home is no longer the principal place of residence of the HOMEBUYER. If the home is sold to another party, the liability of the HOMEBUYER will be limited to the amount of the net proceeds of the sale as set forth below. ________Buyer Initials Recapture Agreement This is a mechanism to recapture all or a portion of the direct HOME subsidy if the HOME recipient decide to sell the house within the affordability period at whatever price the market will bear. The recaptured funds will come from the net proceeds if available. Any such repayment as required shall be made to the Lender no later than thirty (30) days following the action that require the repayment. HOME Program – Homebuyer Written Agreement Page 3 of 5 Obligation of Repayment As security of Borrower’s obligation of repayment, and subject to the terms and conditions of this Agreement, the Borrower grants, and the Lender shall and hereby does have, a lien on the real estate hereinafter described in the full amount necessary to satisfy said repayment obligation and the cost, including reasonable attorney’s fees, of collecting the same. The real estate subject to said lien is legally described as: ALL THAT LOT OR PARCEL OF LAND, situated, lying and being in the City of Augusta, Richmond County, Georgia bounded North by ______. South by ______________, East by ____________ and West by ___________. Parcel # _____________ Property recorded as _______________________, Promptly after the date of any sale, transfer or other conveyance of the above describe property, or in the event of a sale by contract for deed, at least ten (10) days prior to the date of such sale; or if the property shall cease to be the Borrower’s principal place of residency, the Borrower or his/her heirs, executors, or representatives shall give the lender notice thereof. In the event the Borrower or his/her heirs, executors, or representatives shall fail or refuse to make a required payment within said limited period, the Lender may, with or without notice to the Borrower, foreclose said lien in the same manner as an action of the foreclosure or mortgages upon said real estate, as provided by State Statue. Ownership of Property You must hold fee simple title to the property purchased with HOME funds for the duration of your Forgiveness Loan. Use of HOME funds The HOMEBUYER agrees that the HOME assistance will be used to lower the cost of the home by providing down payment assistance. This will reduce the sales price of the home to the HOMEBUYER and reduce the total amount the HOMEBUYER will be required to borrow in order to purchase the home. ________Buyer Initials Household Income You must be an eligible household through the time of filing a loan application with the City or other lender to the escrow closing of the purchase transaction. Income eligibility means that your annual gross household income, adjusted for household size does not exceed eighty percent (80%) of the Augusta-Aiken median income, as established by HUD. Insurance requirement HOME Program – Homebuyer Written Agreement Page 4 of 5 The HOMEBUYER must at all times during the duration of this AGREEMENT maintain a valid and current insurance policy on the home for the current appraised or assessed value of the home. Failure to maintain a valid and current insurance policy will be considered a breach of this AGREEMENT, and the AWARDEE will have the right to foreclose on its mortgage lien if necessary to protect the HOME Program investment. Property standards Pursuant to HOME Program rules, the property that is the subject of this AGREEMENT must meet all State and local housing quality standards and code requirements. If no such standards or codes apply, the property must at a minimum meet the HUD Section 8 Housing Quality Standards/Uniform Physical Condition Standards.

Background:The City of Augusta’s Home Subsidy Program is a loan in the form of a second mortgage. This financial assistance is combined with a primary loan (first mortgage loan) from a participating lending institution and enables a qualified first-time home buyer to become a homeowner. The buyer must be a first- time home buyer and the home must become the buyer’s primary residence. The program is funded by The Department of Housing and Urban Development (HUD) and administered by The City of Augusta’s Housing and Community Development Department (HCD). The program promotes neighborhood stability by assisting with the gap financing toward the purchase price and closing costs for homes located within the city limits of Augusta and in conjunction with local Community Housing Development Organizations (CHDOs) and employees of Augusta, Georgia. One application is awaiting approval to move forward with the process of becoming a homeowner: 1. Homebuyer Subsidy – 809 Spruce St - Requesting: $25,000 Sales Price: $ 87,000.00 Applicant has a first mortgage from a lending institution but needs the Subsidy to complete the process. Once approved, Lenders will schedule closing and the applicant will then become a new homeowner in Augusta, Georgia. Analysis:The approval of the application will enable one individual to become a homeowner and “Make the American Dream a Reality”. Approval will also have a positive impact on the community by increasing the tax base in Augusta, Georgia. Financial Impact:The City receives funding from the US Housing and Urban Development Department on an annual basis. This approval would be for the amount of $25,000.00.

(Requested by Commissioner Sammie Sias) Background: Analysis: Financial Impact: Alternatives: Recommendation: Funds are Available in the Following Accounts: REVIEWED AND APPROVED BY: Energy Project Investment Grade Audit Customer Workshop Document Synopsis of Executive Summary Trane is pleased to provide the following Detailed Energy Audit Report for Augusta-Richmond County. Trane is an international organization with engineers and construction professionals on staff experienced in analyzing and developing comprehensive energy saving programs. The objective of this study was to identify and quantify Energy Conservation Measures (ECMs) at occupied City-owned buildings to reduce the energy consumption. This objective was met by conducting site visits to existing facilities to determine their existing conditions and analyze existing equipment in those buildings. Trane then examined the energy use profiles of each building using actual electricity bills, natural gas bills, and water/sewer bills. Because of the size and complexity of this project, Trane used a variety of modeling strategies to calculate energy baselines and savings, including spread sheet models and Trace 700TM energy models. After determining the buildings’ baseline energy profile, Trane analyzed potential ECMs that would result in a significant energy usage reduction. The energy savings calculated for each measure are compared against the baseline model and historical consumption to validate the quantities of savings proposed. Trane then determined the financial impact of the proposed ECMs using actual utility rate structures, taking into account escalation of utility rates into the future. Augusta-Richmond County’s buildings that are included in this report comprise a total of approximately 1,328,675 ft2 of conditioned space. The types of buildings surveyed included museums, fire stations, police stations, recreation centers, libraries, office/administrative buildings, public pools, and sports arenas. 1.2.5 Mechanical Systems Augusta-Richmond County has many mechanical systems that are past their useful life. Trane used this audit to document, to the best of our ability, the age and condition of existing HVAC equipment in the buildings included in this audit. The mechanical equipment surveyed includes but is not limited to chillers, boilers, pumps, air handling units (AHUs), roof top units (RTUs), split systems, and package terminal units (PTACs). The maintenance costs of keeping aged equipment in serviceable condition is a primary opportunity for operational cost savings discussed in Sub-section 1.4 Major Customer Operational Benefits. A detailed equipment list of all equipment surveyed in this audit is contained in Appendix 4. 1.2.6 Controls Much like the mechanical systems at Augusta-Richmond County, much of the HVAC controls infrastructure is well out of date. While Augusta-Richmond County does have modern direct digital controls (DDC) systems for some of their larger buildings, there are also a number of buildings operating on older pneumatic controls. In most buildings such as libraries, recreation centers, etc., the majority of thermostats that control HVAC equipment are standard electromechanical thermostats or non- programmable digital thermostats. 1.2.9 Utilities The utility providers for Augusta-Richmond County are Georgia Power Company and Jefferson Energy Cooperative for electricity; Scana Energy, Constellation, Walton EMC, and Georgia Natural Gas for natural gas; and the Augusta Utilities Department for water and sewer. The surveyed building’s utilities for the Baseline Year of October 2018 through September 2019 are outlined below. This only includes buildings outlined in Table 1.1. Electric Consumption 25,711,324 kWh Electric Demand 6,346 kW* Electric Cost $2,185,728 Natural Gas Consumption 239,571 therms Natural Gas Cost $233,657 City EUI 94 kBtu/ft2 City ECI $2.04/ft2 Total Utility Spend $2,419,385 *Electricity demand was not provided for all locations. The utility numbers above apply only to the surveyed buildings and do not include roadway lighting, roadway irrigation, parking deck consumption, water and sewer system consumption, etc. The values presented above for EUI and ECI only include the energy usage and associated cost for electricity and natural gas. Water consumption and cost are typically left out of this calculation. 1.3 Summary of Savings The ECMs investigated in this technical analysis are presented in the table below. The economics associated with these ECMs are also presented. The Base Utility Rates are defined in Section 3, and a discussion regarding how the Base Utility Rates were escalated to obtain the Proposed Escalated Cost Savings in Table 2 are also contained in this section. These ECMs have been identified as potential candidates for implementation, and a detailed analyses of all of the ECMs are provided in Section 5. Table 1: Guaranteed Utility and Cost Savings by ECM Category ECM Guaranteed Energy Savings kWh kW Therms kgal $ Savings Lighting Upgrades 4,161,541 6,444 -10,442 0 $434,511 Water and Sewer Conservation 0 0 47,451 16,384 $87,657 Building Envelope Improvements 743,593 612 17,703 0 $106,866 Controls Upgrades 1,817,476 297 13,885 0 $182,201 Mechanical/HVAC Upgrades 348,145 633 7762 0 $52,971 Chiller Plant Improvements 2,374,673 -89 0 0 $110,201 Boiler Plant Improvements -2,314 -3 3647 0 $7,756 Renewable Energy Systems 331,811 0 0 0 $34,006 9,774,925 7,894 80,006 16,384 $1,016,169 * (preliminary) Cost savings equate to an approximate 40% reduction in electric and gas utility costs 1.4 Major Customer Operational Benefits Implementing the described measures has many benefits in addition to reducing facility energy consumption and associated cost. In most instances, maintenance costs will also be reduced due to a reduction in equipment operating hours and/or loads imposed on equipment, and installation of longer life materials. Replacing old equipment nearing the end of its useful life will also reduce maintenance costs and eliminate future replacement costs. New system designs often improve system diagnostics, detecting, and repairing problems before building occupants are aware they exist. Lighting system retrofits often improve space lighting level and HVAC measures often result in improved space comfort conditions and indoor air quality. Spaces are more pleasant to occupants, which often results in an increase in productivity. The operational savings benefits Trane identified during the Detailed Energy Audit, with input from Augusta-Richmond County personnel, are summarized below. Table 2: Summary of Operational Savings Operational Savings shown here are based upon past and projected expenditure data . As a direct result of the work to be performed by Trane, the Customer shall achieve annual operational cost savings in the amounts set forth in the table below during the Guarantee Term. Description A - Direct Cost Avoidance B - Indirect Cost Avoidance C - Capital Cost Avoidance Annual BAS Service Savings $19,213 Annual Lighting Operation Savings $70,047 Capital Cost Avoidance $241,649 Total $89,260 $0 $241,649 A Direct Cost Avoidance: Reduction or elimination of costs or expenses in connection with existing or planned service contracts, materials, supplies, energy costs and labor expenditures. Direct cost avoidance Operational Savings may include savings achieved through a reduction in fuel and/or electricity rates (“Energy Rate Optimization Savings”) by one or more of the following means: (i) Improved rate from local electric utility company, natural gas company, or fuel company; (ii) Direct purchase of natural gas or electricity; and/or (iii) Bulk purchase of fuel. B Indirect Cost Avoidance. Customer valuation, including such items are re-deployed labor resources and reduction in overhead C Capital Cost Avoidance. Future replacement expenditures avoided as a result of new equipment installed. Key Takeaways from Section 1:  The proposed project consists of LED lighting upgrades, building envelope improvement, water efficiency upgrades at Webster Detention Center, HVAC and Building Automation (controls) upgrades at approximately (25) buildings, and solar PV renewable energy  Implementation of recommended ECMs (energy conservation measures) is projected to reduce ARC’s buildings utilities spend by approximately 40%  All costs associated with the proposed ~$24M project (debt service and Trane on-going services) are projected to be offset by the financial benefit generated by the combination of guaranteed energy savings and operational savings forecasted over an (18) year term, combined with a $4.5M Customer capital contribution. 5. Baseline Analysis (and Energy Savings) Calculation Methodology Trane used existing building utility data (consumption and cost) incurred during the October 2018 through September 2019 (the Baseline Period) to tune and calibrate spreadsheet and Trane Trace 700 energy models which were used to simulate baseline energy consumption. Building energy consumption was modeled again after ECMs were employed. Calculated energy savings (kWh of electricity and/or therms of natural gas) were calculated based on the difference between baseline energy consumption and ECM post retrofit energy consumption. Calculated energy savings were multiplied by a guarantee safety factor in order to obtain the value of guaranteed energy savings. Utility dollar savings values were derived based on the quantity of guaranteed energy savings multiplied by the baseline utility rate applicable to each ECM employed in a given building. These utility dollar savings were escalated throughout the course of the (18) year proposed project finance term by a utility escalation rate of 3% per annum which was used to model inflationary effects on utilities. Key Takeaways from Section 5:  Energy unit savings (kWh, Therms, etc.) are guaranteed by Trane.  Energy dollar savings are not guaranteed by Trane; ESCOs (energy service companies) like Trane are prohibited by federal and state law from guaranteeing energy dollar savings.  The value of energy dollar savings is escalated at a fixed rate during the finance term to account for inflationary changes / increases in utility rates 6. Energy Conservation Measure Evaluation Trane is proposing ECMs for (89) separate facilities in this project. The ECMs, which will result in both annual energy and cost reduction, can be divided into 6 categories. These categories are: 1) Lighting Fixture and System Retrofits and Improvements 2) HVAC (Heating Ventilation and Air Conditioning) System Improvements 3) Controls (for building mechanical and electrical systems) Improvements 4) Water (domestic) Fixture Retrofits and Improvements 5) Solar PV installations 6) Building Envelope (Walls, Windows, Doors, Roof) Improvements Details on these ECMs is presented in this section.

Unless a building has been built or renovated in the past few years, it is common to find extensive use of fluorescent, metal halide, and incandescent fixtures throughout the building. These older lighting technologies are a product of their time and often remain without intentional replacement. Older lighting technologies require more wattage to produce the same amount of light as LED fixtures. This results in more electrical energy consumption for lighting systems and also a higher heat output from the lamps which raises HVAC cooling costs. For this measure, existing fluorescent, metal halide and incandescent lighting fixtures will be replaced/retrofitted with new LED tubes, lamps, retrofit kits, and/or fixtures. This will greatly reduce the energy required to illuminate the building. Additionally, cooling systems will have to run less often to offset the heat generated by the lighting. There are several additional benefits to LED lighting technology. LED lighting has longer burn hour life, faster on/off response time, and easier dimming capabilities compared to fluorescent and incandescent technologies. Because LED light fixtures have longer burn hour life, this will reduce the material and time cost of replacing burned out lamps. This is especially advantageous in building areas with high ceilings, such as high-bay areas, where the maintenance costs associated with lamp replacements includes renting or obtaining lifts to reach the fixtures 6.2 HVAC Scope and ECMs As part of the scope of this project, Trane will be furnishing and installing several different HVAC system types and implementing different Energy Conservation Measures (ECMs) including those listed in the table below. Most of the new equipment and systems that will be installed serve to replace and/or to retrofit existing HVAC equipment and systems. The table below provides a listing of the ECMs which will be implemented in each building. A description of each of these ECMs is presented in the body of this section below.

In some cases, new cooling towers will be installed to accompany these new chillers. The existing chillers to be removed as part of this measure are older, degraded efficiency chillers. These machines provide chilled water to coils in air handling units and fan coils to cool the building. Cooling towers provide condenser water which accepts heat rejected from a chiller and transfers it to the environment (outdoors) via evaporative cooling. Over time, chillers lose efficiency due to fouling, which is the build-up of contaminants on the heat exchanger surfaces. Chillers also lose efficiency as they age due to corrosion and typical wear on moving parts. Additionally, the chillers being replaced are 20 years old or older and nearing the end of their useful life. Replacing them in this project will eliminate capital replacements costs in the near future. The new chillers that are installed will provide a higher IPLV (integrated part-load value) than the existing chillers they will replace, thereby providing cooling operation energy savings. The new chillers also support variable flow through the evaporator barrels, which allows pumping systems to be converted to lower power consuming variable flow set-ups. Also, with the newer on-board controllers, Tran can employ chiller/tower optimization control Affected Equipment This measure is proposed for two locations: The Augusta Municipal Building, and The Charles B. Webster Detention Center. Note that the cooling tower replacements will only occur at the Detention Center’s older plant, as the towers for the Detention Center’s newer plant, and the towers at the municipal building are in decent shape. Below is a list of equipment affected by this measure.

Direct expansion (DX) air conditioning equipment is the technical name for typical residential and small commercial style rooftop units and split systems. Many Augusta facilities are cooling and heated with these systems. DX systems consist of a refrigerant loop, in which the refrigerant is compressed and expanded at different points of the loop to transfer thermal energy. Typically, a refrigerant coil is placed directly in the supply air stream, where the refrigerant absorbs thermal energy as it evaporates and expands. Thermal energy is rejected at a compressor, where the refrigerant is compressed and condenses, rejecting the heat that was removed from the supply air steam. Over time, HVAC units degrade in operational efficiency as coil surfaces oxidize on the exterior and sometimes scale on the interior which reduces heat transfer efficiency. The moving mechanical components also wear, which further reduces the operational efficiency of the equipment. The new equipment will be installed in place of the existing equipment, including providing new refrigerant line sets for all split systems. Additionally, older DX equipment uses R-22 as its refrigerant, which has been phased out in favor of newer refrigerants with lower adverse environmental impact. Because it has been phased out, R-22 is far less available, meaning increased maintenance costs if additional refrigerant is required. ARC has already undertaken future budgetary preparation for replacing these older air conditioning systems which utilize R-22 refrigerant, therefore Trane has financially accounted for the avoidance of this need as Capital Cost Avoidance. Existing refrigerant will be handled and disposed of in a manner consistent with local environmental requirements.

Filters are a required AHU component throughout any facility for cleanliness and IAQ concerns. Newer technology in filters can give excellent performance with regards to particle filtration with less pressure drop than older technology. Electrostatic filter technology combines the benefits of passive filtration with those of electro-static attraction. A charge is applied to the filter, which polarizes the media and the surrounding particles. This causes particles in the air to be attracted to the filter and stick to it, including very fine particulates as well as gas contaminants which traditional air filters cannot capture. Due to this, the filters don’t need to be as invasive to the airstream, and there’s less pressure drop across the filter. 6.2.4 Bipolar Ionization FIMs are measures intended to improve the operation and value of building systems but are not associated directly with energy savings. This measure proposes to install bipolar ionization units as a means to improve indoor air quality. Bipolar ionization works to clean the air by producing ions, which induce the particles in air to clump together and become caught in the filters. This also helps reduce odors and airborne pathogens while simultaneously cleaning the coils of HVAC equipment. The improved indoor air quality has also been shown to lead to greater levels of occupant attentiveness, productivity, and comfort, and can reduce the number of airborne infectious disease particulates, including SARS-CoV-2 which causes COVID-19, from the air. Global Plasma Solutions conducted a study of their bipolar ionization technology and its effectiveness in reducing SARS-CoV-2 from the air, and found that it’s possible that it could eliminate 99.4% of the virus from the air in 30 minutes of continuous use. (Aircare Engineering, 2020 Sept 15, “Global Plasma Solutions (GPS) Launches Needlepoint Bipolar Ionization to Virtually Eliminate Static SARS-CoV-2 with Proprietary NPBI™ Technology”, PR Newswire, https://www.prnewswire.com/in/news-releases/global-plasma- solutions-gps-launches-needlepoint-bipolar-ionization-to-virtually-eliminate-static-sars-cov-2-with- proprietary-npbi-tm-technology-860417185.html) 6.4 Controls Scope and ECMs Under the scope of this project, Trane will be providing Augusta-Richmond County with a Tracer Ensemble Enterprise (Tracer ES) building automation system which allows multiple buildings to be managed as a single enterprise. The Tracer ES will reside on Trane’s “Trane Connect” Cloud Based Servers via locally installed digi routers in each facility. This network will receive and store building data that is being gathered from each individual building’s system level controllers. The Tracer system will also consist of a centralized and interactive graphical user interface. In addition to the centralized user interface, the Tracer ES offers remote access via the Web as well as mobile devices, allowing the Augusta-Richmond County enterprise of buildings to be effectively managed from nearly any location by authorized facility’s staff. At the individual building level, Trane will be providing Tracer System Controllers (Tracer SC’s). These controllers will be the “brain” of each building in terms of building automation. Like the Tracer ES, each Tracer SC will offer remote access via the Web as well as mobile devices. At many of the smaller sites, the Tracer SC will be paired with a Tracer Concierge touchscreen display, offering the end user with the ability to toggle set points with the touch of a finger. End devices and unit controllers in each building will ultimately tie back to that building’s Tracer SC via wireless and/or wired communications. The Tracer SC will also offer device graphics and floor plan graphics, which will aid facility’s staff in physically locating issues that need to be addressed. Trane controls systems will enable the Augusta-Richmond County Facilities Team to efficiently manage buildings from nearly anywhere with one system, leading to high performance and consistent comfort in each building. The centralized interface will allow facilities staff to monitor buildings across Augusta- Richmond County from a single access point. This will reduce response time to possible issues, often without having to spend time traveling from building to building. Staff can manage and respond to alarms, change set points, and modify schedules conveniently from their computers. Many operational improvements will also be seen in each individual building. Each building can be custom scheduled to match building occupancy so that mechanical equipment runs only when it is needed. This leads to energy savings, extended system life, and reduced lifecycle operating costs. Alarms will be sent to established facilities staff, informing them of any issues that need to be addressed in the building. This real time data helps reduce response time and enables predictive maintenance. Lastly, Trane control systems offer graphics that allow staff to easily navigate between equipment and find the root cause of a problem leading to greater occupant comfort.

Webster Detention Center) with older DDC controls will be upgraded to New Trane systems and interconnected back to the central Tracer ES. Additionally, Trane teams will provide a full retro-commissioning of air-side and water-side systems, replacing malfunctioning hvac equipment. All controls equipment in this building will be replaced or upgraded as part of this retrofit. The new system will be programed with a suite of energy savings strategies to reduce energy consumption of HVAC systems. The following strategies will be used - HVAC system scheduling and setback - Temperature setpoint optimization - Optimum Start (morning warm-up) - Static Pressure Reset - Airflow/Ventilation Improvements - Fan Cycling Optimization - Chiller plant/Cooling Tower Optimization - Condenser Water Reset While this controls upgrade and Retrocommissioning (RCx) effort is described as one measure, there are a variety of upgrades that will be made specifically due to RCx efforts. Retrocommissioning is being performed in all facilities to identify and correct potential unknown operational issues with hvac and controls equipment. However, Trane is already planning for a number of known issues included for the Judicial Center, identified by Trane personnel. HVAC System Scheduling and Setback (All facilities) These three Augusta-Richmond County buildings are conditioned at the same space temperature set point on a 24/7/365 basis even though parts of these buildings are occupied only a portion of the time (Monday – Friday daytime hours for example). Scheduled HVAC setback turns off or sets back HVAC systems during unoccupied times and is the controls measure which will provide the greatest quantity of energy savings. This ECM involves implementation of space temperature set point reset / setback schedules for each building area and system which does not exhibit constant occupancy. Humidistats will also be incorporated to initiate air-conditioning system operation override, as needed, to prevent excessive relative humidity during unoccupied time periods. Table 8: Occupied versus Unoccupied Cooling and Heating Setpoint Values State Cooling Setpoint Heating Setpoint Occupied 72°F 70°F Unoccupied *82°F 60°F *subject to RH or humidistat feedback Blythe Area Recreation Center is presented as an example facility for which unoccupied temperature setback control is proposed.

This will include taking control of the chiller, economizer loop, chilled water pumps, tower fans, condenser water pumps, changeover valves, and plant actuators. As part of this measure, the new system will support the all- variable chilled water flow ECM. Trane will accomplish this through all new Trane controls, reprogramming the entire plant for Variable Flow operations, along with Trane’s patented ‘Tower Optimization’ programming sequence. The Trane systems approach to minimization of cooling tower chiller subsystem energy use is unique. It uses a powerful algorithm to model the interaction of the cooling tower and chiller using real-time ambient conditions and chiller loading to calculate the optimal setpoint. Other systems use a broad assumption concerning the best method for determining the optimal setpoint to operate a cooling tower. The Trane strategy determines the cooling tower setpoint that minimizes the system energy usage. Trane will also program the system to utilize the existing piping and valve arrangement for free cooling /economizer during the cooler parts of the year, in support of the re-commissioning of the Water-side economizer ECM. This will be programmed as a building changeover system, controlling the existing valve actuators and tower water temperature to achieve this during colder outside temperatures. This new plant configuration will correlate into substantial energy savings, and improved tenant comfort. Building Name Input Name Existing Value Proposed Value Augusta Municipal Building Chiller Minimum Condenser Water Temperature 79°F 60°F Cooling Tower Equipment Type Cooling Tower (DOE) Optimized Tower (DOE) T Below is a list of buildings that are in scope for energy savings associated with water fixture upgrades. For detailed information regarding the audit, refer to the water audit appendix. Given the low water rate in Augusta and that facilities outside of the Detention Center do not pay for sewer service, water conservations measures were only financially feasible at this location. 6.5 Water Efficiency Retrofit This measure proposes to replace existing plumbing fixtures, such as toilets, urinals, sinks, and showers, with low-flow fixtures. Toilets and urinals are rated based on the amount of water per flush, while showers and sinks are rated on their flow rate during use. Over time, building codes have changed to mandate lower flow fixtures than were previously allowed. Advances in technology allow for new low- flow fixtures to provide similar performance while using a fraction of the water. The existing fixtures will be replaced, including all wear parts, with new low-flow equivalents. Replacing wear components puts the entire assembly back to its original condition and eliminates any potential for existing degradation to affect the new fixtures. While existing low flow fixtures may be excluded from this measure, including the replacement of their wear components will lead to standardized parts as well as resetting the expected lifespan of the fixtures, both of which reduce maintenance costs. Detailed information regarding the water retrofit can be found in Appendix 2. Table 10: Water and Sewer Conservation Facilities Affected Building Name Water Efficiency Retrofit Cooling Tower Credit Flush Valve Control Ozone Laundry Charles B Webster Detention Center X X X X Cooling Tower Credit Often when water gets billed from a utility company to the customer, it is assumed that all water that is used by the customer is going to make its way to the sewer, so the total amount of water delivered is also assumed to be the same amount of water for the purposes of sewer charges. While this is true of many processes that use water, in the case of cooling towers this assumption is not true. Cooling towers use water evaporation to cool down the condenser water loop, and hence there’s no sewage produced by cooling towers. As a result, this project proposes to put a water meter on the cooling tower make-up water line and getting a sewage credit for that water that is used by the cooling tower make-up water, hence only being charged for the water being delivered to the cooling towers and not the sewage charge. Flush Valve Control Often in detention centers, water closets can get abused and used way more by the inmates for various purposes, such as trying to eradicate evidence of contraband or just repeatedly flushing the toilet for no reason. This project proposes to install a Flush Valve Control system that helps reduce the amount of times that inmates can flush the toilet in a short period of time. This allows remote access of parameters, and can set how many times inmates can flush the toilet in a certain amount of time. It is also capable of locking out flushing for a period of time if it detects abuse. This can greatly reduce the amount of water consumption used by the Detention Center. Ozone Laundry This measure proposes installing an Ozone Laundry System at the Detention Center. The oxidation of the ozone sterilizes the fabrics with a 99%+ bacterial and viral kill count, reducing risk of spreading pathogens throughout the prison. Other benefits included reduced hot water usage. This can reduce hot water usage up to 80% depending on local groundwater temperatures. Fabric drying times are also shorter, as the ozone helps release moisture in the dryer, reducing drying times by up to 20% in most cases. This furthers energy savings by reducing energy consumption by the dryers. 6.6 PV SOLAR SCOPE AND ECMS This measure proposes to install a solar photovoltaic assembly to convert solar radiation into electrical energy for use in the building. Only the Municipal Building and Diamond Lakes Library/Robert Howard Community Center are in scope for this measure. Electricity is typically provided by the utility company, who sets the tariff schedule and associated costs. Depending on the utility profile, there may be separate charges for consumption and demand. Utilizing a source of free energy such as solar radiation can offset significant utility energy costs. Additionally, it is more environmentally friendly than purchasing electricity from the utility provider, as there are no grid distribution losses and uses a 100% renewable energy source. A solar photovoltaic assembly, consisting of panels with semiconductor materials, will be installed in an area that receives large amounts of sunlight throughout the day. When sunlight contacts the panels, electrons are knocked free from the semiconductor material. Electric fields within the panels push the electrons to conducting plates which transfer the electrons to wire, creating electricity for use in the building. The image below shows how the photovoltaic cells work to produce an electrical current. Figure 1: Photovoltaic Cell Below is a list of buildings that are in scope for energy savings associated with building envelope improvements. For detailed information regarding the PV solar upgrade, refer to Appendix 11. Table 11: PV Solar Facilities Affected Building Name Peak kW Annual kWh Augusta Municipal Building 108 kW 209,796 kWh Diamond Lakes Library and Robert Howard Community Center 100 kW 186,642 kWh 6.7 BUILDING ENVELOPE SCOPE AND ECMS Trane has identified five categories of building envelope improvements for Augusta-Richmond County. A description of each building envelope improvement is below as well as a matrix showing which improvement types are applicable to each building.  Air Leakage/Penetrations – Usually occur where building envelope elements are connected, where penetrations exist, or where cracks have developed over time. Various techniques will be used to seal these openings including insulation, drywall, polyurethane spray foam, and urethanized elastomeric sealants.  Air Leakage/Windows – Occurs where the window frames are attached to the walls. These areas will be caulked with a premium urethanized elastomeric sealant.  Conduction/Insulation – Heat transfer occurs in attic and plenum spaces where there is insufficient insulation. In these areas, polyurethane spray foam, standard batt insulation, or blown-in insulation will be applied.  Weatherstripping/Exterior Doors – Weatherstripping, door sweeps, and vertical door sweeps on exterior doors and even roll-up doors gets old, brittle, or cracked and allows air infiltration.  Compartmentalization – When not properly sealed (or compartmentalized), pipe chases and other vertical shafts can allow stack effects to exist. This creates air infiltration/exfiltration and drafty conditions within a building. These areas will be properly sealed to eliminate the stack effects. 6.8 OPERATIONAL SAVINGS Implementing the described measures has many benefits in addition to reducing facility energy usage and associated cost. In most instances, maintenance costs will also be reduced due to a reduction in equipment operating hours and/or loads imposed on equipment. Replacing old equipment nearing the end of its useful life will also reduce maintenance costs. New system designs often improve system diagnostics, detecting, and repairing problems before building occupants are aware they exist. Lighting system retrofits often improve space lighting level and HVAC measures often result in improved space comfort conditions and indoor air quality. Spaces are more pleasant to occupants, which often results in an increase in productivity. The operational savings benefits Trane identified during the Detailed Energy Audit for the Augusta Richmond County are detailed below. Lighting The anticipated service life of most of the new LED kits and other components that will be installed as part of the proposed project work is 50,000+ hours implying that these lighting materials should last longer than the finance period of the proposed project (18 years). Therefore, it is reasonable to anticipate that Augusta Richmond County will no longer need to purchase lighting replacement materials including lamps and ballasts. Controls Service The proposed energy project includes controls service support which will eliminate the need for Augusta Richmond County to continue to procure a number of existing controls service contracts in the future. 6.8.2 Capital Cost Avoidance Much of the Customer’s existing HVAC equipment and systems are near the end of useful service life or past the end of useful service life (e.g., operating at reduced capacity and/or efficiency, or not operating at all). Implementation of new HVAC equipment as part of proposed Services Trane will furnish will reduce the need for the City to procure replacement HVAC equipment in many of the City’s buildings over the course of Guarantee Term. Trane quantified the value of aforementioned equipment near or at the end of useful service life as presented in the tables below. Table 12: Future replacement expenditures avoided as result of new equipment installed.

M&V METHODOLOGY Trane is proposing a Measurement and Verification (M&V) plan that will provide Augusta Richmond County with verification of project guaranteed savings while balancing costs incurred during the M&V process. This section provides an overview of the M&V process, guidelines for the M&V approach, and details on how each ECM will be handled. Trane’s team have selected both Option A and Option C methodologies for different ECMs and locations. 7.1.1 IPMVP Protocol Trane adheres to the well-established International Performance Measurement and Verification Protocol (IPMVP) for confirming the benefits of the installed ECMs. The four IPMVP methods are summarized below. Together, we will select whichever Option proves to be the most prudent for each individual ECM after the project is fully developed. IPMVP Protocol Typical Uses for this Option Retrofit Isolation: Key Parameter Measurements Option A is applied to ECMs where there is one specific and key variable that best indicates the potential for energy savings. Retrofit Isolation: All Parameter Measurements Verification techniques for Option B are designed for projects where long-term continuous measurement of performance is desired. Whole Facility Verification techniques for Option C determine savings by studying overall energy use in a facility and identifying the effects of energy projects from changes in overall energy use patterns. Calibrated Simulation Option D is intended for energy retrofits where calibrated simulation of baseline energy use and calibrated simulations of post-installation energy consumption are used to measure savings from the retrofit. 7.2 M&V ECM TABLE The following table details the proposed M&V methodology, by IPMVP Option category, for each proposed ECM.

Key Takeaways from Section 7:  The Trane team has assembled a measurement and verification program which will serve to ensure the persistence of energy savings over the course of time. 8. TRANE SERVICE Trane plans to provide two types of on-going service once the proposed energy performance contract is implemented and commissioned. This service offering consists of the following: Mechanical-HVAC service, and Building Automation System (BAS) - TIS (Trane Intelligent Services) - M&V (measurement and verification) service. Georgia energy performance contracting statute requires that Trane provide M&V and accompanying services necessary to maintain the energy performance guarantee during the first year of the project finance term. Afterward, Trane and ARC will have the opportunity to renew this service agreement during each year of the finance term. The proposed services that Trane will provide serve to ensure optimal comfort and energy performance, and to enhance the perpetuity of energy savings that ARC will benefit from over the course of time. Trane will require that the BAS-TIS-M&V services remain in force to maintain the energy performance guarantee during the finance term. The cost for all of the aforementioned services is included on a continuing basis as part of the energy project cash flow proforma. 8.1 Mechanical-HVAC Service The following table summarizes the proposed services that Trane will provide regarding the mechanical-HVAC service.

EXECUTIVE SUMMARY 1.1 ENERGY AUDIT DEVELOPMENT INFORMATION Trane is pleased to provide the following Detailed Energy Audit Report for Augusta-Richmond County. Trane is an international organization with engineers and construction professionals on staff experienced in analyzing and developing comprehensive energy saving programs. The objective of this study was to identify and quantify Energy Conservation Measures (ECMs) at occupied City-owned buildings to reduce the energy consumption. This objective was met by conducting site visits to existing facilities to determine their existing conditions and analyze existing equipment in those buildings. Trane then examined the energy use profiles of each building using actual electricity bills, natural gas bills, and water/sewer bills. Because of the size and complexity of this project, Trane used a variety of modeling strategies to calculate energy baselines and savings, including spread sheet models and Trace 700TM energy models. After determining the buildings’ baseline energy profile, Trane analyzed potential ECMs that would result in a significant energy usage reduction. The energy savings calculated for each measure are compared against the baseline model and historical consumption to validate the quantities of savings proposed. Trane then determined the financial impact of the proposed ECMs using actual utility rate structures, taking into account escalation of utility rates into the future. In addition to this report, Trane has included an extensive series of appendices. Because of how voluminous these appendices are, they are being provided to Augusta-Richmond County electronically and are not part of the main body of this report. Included in these appendices are the lighting fixture line-by-line audit, the building envelope line-by-line audit, water audit, rate structures, and Trace 700TM methods for estimating savings and spreadsheet methods for estimating savings. 1.2 BRIEF DESCRIPTION OF FACILITIES Augusta-Richmond County’s buildings that are included in this report comprise a total of approximately 1,328,675 ft2 of conditioned space. The types of buildings surveyed included museums, fire stations, police stations, recreation centers, libraries, office/administrative buildings, public pools, and sports arenas. The list of buildings that were surveyed includes buildings as old as the Old Government House, which was built in 1801, to recently constructed buildings. Geographically, the buildings are spread throughout the eight City districts. All facilities where energy retrofit work is planned and their addresses are as follows.

Many of the older vintage T12 have been replaced by T8 fluorescent fixtures, but there are still a considerable number of T12s and T8s remaining in the buildings included in this audit. In addition to linear fluorescent fixtures, there are also compact fluorescent luminaries, incandescent luminaires, halogen luminaires, LED luminaires, metal halide luminaires, and U-Bend luminaires. The exterior fixtures predominantly include metal halide lighting fixtures, halogen lighting fixtures, high pressure sodium lighting fixtures, high wattage incandescent lighting fixtures, LED lighting fixtures, linear fluorescent lighting fixtures, and compact fluorescent lighting fixtures. 1.2.2 Lighting Systems 4 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only A complete list of all lighting fixtures and quantities can be found in Appendix 1. Water efficiency retrofits were conducted at the locations in the table below. Although audits were conducted at these location, water and sewer conservation measures were only economically feasible at the Charles B. Webster Detention Center. The reasoning behind this is the water rates are low, and the other buildings do not pay sewer charges.

Webster Detention Center Richmond County Correctional Institute Augusta Airport Sign Shop AED Central Services Robert Howard Community Center Augusta Animal Services Blythe Area Recreation Center Richmond County Sheriff’s Training Center Water fixtures including toilet flush valves, faucets, and showerheads were audited at the Charles B. Webster Detention Center. The large portion of water fixtures surveyed during the audit were high flow fixtures: 3.5 gallons per flush (gpf) water closets, 3.7 gallons per flush (gpf) water closets, and 1.6 gpf urinals. Approximately half of the water closet fixtures were also found to be 1.6 gallons per flush (gpf), which are not being changed out. Other water conservation measures include a cooling tower retrofit, cooling tower credit, ozone laundry system measure, and flush valve controls. A complete list of all fixtures included in the water audit and savings measures can be found in Appendix 2. There are a number of different construction types throughout all the buildings surveyed during this audit. These construction types are related to the vintage of the building, the function of the building, and the needs of the building occupants. One major need that was addressed in this audit is detailing the deficiencies in the building envelope at the Municipal Building. 1.2.3 Water and Sewer Conservation 1.2.4 Building Envelope 5 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only A complete list of all buildings included in the building envelope audit can be found in Appendix 3. Augusta-Richmond County has many mechanical systems that are past their useful life. Trane used this audit to document, to the best of our ability, the age and condition of existing HVAC equipment in the buildings included in this audit. The mechanical equipment surveyed includes but is not limited to chillers, boilers, pumps, air handling units (AHUs), roof top units (RTUs), split systems, and package terminal units (PTACs). The maintenance costs of keeping aged equipment in serviceable condition is a primary opportunity for operational cost savings discussed in Sub-section 1.4 Major Customer Operational Benefits. A detailed equipment list of all equipment surveyed in this audit is contained in Appendix 4. Much like the mechanical systems at Augusta-Richmond County, much of the HVAC controls infrastructure is well out of date. While Augusta-Richmond County does have modern direct digital controls (DDC) systems for some of their larger buildings, there are also a number of buildings operating on older pneumatic controls. In most buildings such as libraries, recreation centers, etc., the majority of thermostats that control HVAC equipment are standard electromechanical thermostats or non-programmable digital thermostats. Many of the Augusta-Richmond County’s buildings have plug loads that add to the electrical consumption of each building. These plug loads include items used for occupant comfort: fans and space heaters. It also includes standard office equipment such as computers, monitors, printers, and copiers. Many of the facilities have kitchens and break rooms that include additional building loads such as refrigerators, electric or gas stoves, microwaves, vending machines, and coffee makers. There are also some pools with pool pumps. There are no measures in scope to reduce energy consumption occurring from miscellaneous loads. Building occupancy depends on the function of each individual facility. Fire stations and police stations often operate around the clock, while offices are typically occupied 8AM to 6PM. There is a wide range of occupancy types that were accounted for and discussed in the Existing Buildings and Systems Descriptions. Occupancy details, where known, are noted in the existing facility descriptions The utility providers for Augusta-Richmond County are Georgia Power Company and Jefferson Energy Cooperative for electricity; Scana Energy, Constellation, Walton EMC, and Georgia Natural Gas for natural gas; and the Augusta Utilities Department for water and sewer. The surveyed building’s utilities for the Baseline Year of October 2018 through September 2019 are outlined below. This only includes buildings outlined in Table 1.1. Electric Consumption 25,711,324 kWh Electric Demand 6,346 kW* Electric Cost $2,185,728 Natural Gas Consumption 239,571 therms Natural Gas Cost $233,657 City EUI 94 kBtu/ft2 City ECI $2.04/ft2 Total Utility Spend $2,419,385 *Electricity demand was not provided for all locations. 1.2.5 Mechanical Systems 1.2.6 Controls 1.2.7 Miscellaneous Loads 1.2.8 Occupancy 1.2.9 Utilities 6 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only The utility numbers above apply only to the surveyed buildings and do not include roadway lighting, roadway irrigation, parking deck consumption, water and sewer system consumption, etc. The values presented above for EUI and ECI only include the energy usage and associated cost for electricity and natural gas.

In most instances, maintenance costs will also be reduced due to a reduction in equipment operating hours and/or loads imposed on equipment, and installation of longer life materials. Replacing old equipment nearing the end of its useful life will also reduce maintenance costs and eliminate future replacement costs. New system designs often improve system diagnostics, detecting, and repairing problems before building occupants are aware they exist. Lighting system retrofits often improve space lighting level and HVAC measures often result in improved space comfort conditions and indoor air quality. Spaces are more pleasant to occupants, which often results in an increase in productivity. The operational savings benefits Trane identified during the Detailed Energy Audit, with input from Augusta- Richmond County personnel, are summarized below. A detailed description of these operational savings categories and the computation thereof can be found in Section 6. Table 4: Summary of Operational Savings Operational Savings shown here are based upon past and projected expenditure data .

The building is located at 4164 Mack Lane and is approximately 17,500 square feet. Lighting Systems Lighting at the Augusta Animal Services building is mainly T8 linear fluorescent luminaires, although there are also some compact fluorescent and U-bend fluorescent fixtures throughout the interior as well. All exterior fixtures are 100-, 400-, 50-, and 70-watt metal halide luminaires. A complete list of all lighting fixtures and quantities can be found in Appendix 1. Building Envelope This Augusta Animal Services building has a cement façade with a pitched metal roof. Interior walls are painted cement block. There are double pane glass windows throughout the building exterior. Mechanical Systems The building is served by an air-cooled chiller on grade. The existing Trane chiller is approximately 17 years old, and 70 tons. Chilled water is distributed through the chiller and building air handling units via an existing constant speed chilled water pump. The existing chilled water circulation pump is installed in a mechanical room on the mechanical mezzanine in the building. The air-cooled chiller supplies chilled water to one energy recovery unit and six (6) blower coil units in the building. The SEMCO energy recovery unit provides 100% outdoor air to the building for ventilation air to the blower coil units as well as all conditioned air to the animal kennels. Air is exhausted from the animal kennels and building restrooms by this unit. The unit also has a chilled water coil to de-humidify and cool the outside air after the enthalpy wheel and a hot water coil to heat the air during the winter. The sensible wheel adds re-heat to the airstream after the cooling coil to supply neutral air to the kennels and blower coil units. The energy recovery unit and blower coil units are located within the building on a mechanical mezzanine. There is also one electric hot water boiler and one domestic water boiler on site. 15 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Controls There are four zone sensors that control the building.

Facility improvement measures (FIMs) are measures intended to improve the operation and value of building systems but are not associated directly with energy savings. The Animal Services center is experiencing Chiller failure and unwanted odor propagation. The mechanical system will be upgraded to improve overall HVAC system performance. Below are the goals of this upgrade.  Replacement of the Chiller to ensure cooling reliability and availability  HVAC repair to eliminate animal odor propagation into office areas of the building  Ensure reasonably efficiency operation of HVAC system  Control Upgrades The existing Trane air-cooled chiller will be replaced with a like for like replacement. The existing chiller is approximately 17 years old and is nearing the end of its usable life. The chiller has operational issues and a reduced operating efficiency due to age and degradation. A new chiller will provide a more efficient operation and reduce electrical consumption as well as provide more reliable operation and less maintenance. The existing chilled water piping will be removed from the existing chiller connections back to shut-off valves. New piping will be installed as required to connect to the new chiller. The new chilled water piping will be provided with insulation. Factory controls will be provided with the new chiller, including a touchpad interface for stand-alone chiller control. The chiller shall be interlocked with the chilled water pump to start the pump when the chiller starts. The chilled water chemical pot feeder will be valved off to prevent condensation. The new chiller and piping system will be filled and flushed with new chemical added as necessary to accommodate newly the installed chiller. The leak on the pump discharge of the chilled water pump will be corrected. Existing electrical feeders and disconnects to the existing air-cooled chiller shall be re-used with the new chiller. The energy recovery unit (ERU-1) will be re-furbished to return it to original design operation. All leaks in the supply ductwork form the ERU and the six (6) Trane blower coilers will be sealed. All supply and return ductwork throughout the building will be cleaned to remove accumulated dirt and pet hair. This included turning vanes and dampers in the ductwork. The duct liner will be removed in the exhaust ductwork. All outside air duct connections to the blower coil units will be inspected and verified for proper connections. Any found to be disconnected will be reconnected. All supply and return air grilles in the building will be cleaned to remove and dirt and objects restricting airflow. 0 50 100 150 200 250 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec DE M A N D ( K W ) Monthly Electrical Demand kw Poly.

Any found to have improper operation will be restored to fully operable condition. The entire HVAC system will be rebalanced to design airflow conditions. Bipolar ionization will be installed on devices in the return air section of each blower coil unit. The existing boiler will have new boiler controls installed, including a new stand-alone DDC controller for the heating hot water system. A new DDC control system will also be installed for the entire facility. Energy impact at Augusta Animal Services is not discussed under this IGA given that this location was handled under a separate contract. Only savings from lighting improvements measures are discussed in this report for this location. 2.4 Augusta Aquatic Center Site Overview Located at 4164 Mack Ln, the Augusta Aquatic center is an indoor public pool and is approximately 46,840 square feet. The pool is not only accessible to the public for open swim but is also used to host swim meets for local schools as well as league swim meets. There is a food court, offices, men and women’s locker rooms, a weight room, as well as meeting room located in the building. Lighting Systems The interior lighting at the Augusta Aquatics Center is T8 linear fluorescent fixtures. There are also metal halides located in the pool room. The exterior perimeter lighting consists of metal halide lamps as well as high pressure sodium lamps. A complete list of all lighting fixtures and quantities can be found in Appendix 1. Building Envelope The building is one story and built on a flat lot. The building has a brick and masonry façade and interior walls are sheetrock or block. The exterior is in good condition. Majority of the windows are located at the front of the buildings at the main vestibule entrance. There are three windows located at the back of the building. Windows are double paned glass. 18 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Mechanical Systems The natatorium portion of the building is served by two PoolPak dehumidification units located in the mechanical mezzanine. The units are packaged units with remote air-cooled condensers located outside on grade. These units have hot water reheating coils for heat. The hot water loop has three primary hot water pumps. There are six pool pumps for water circulation. Heating hot water is supplied by two Peerless natural gas fired boilers for pool heating and heat to the dehumidification units. The system also includes heat recovery from the dehumidification units for heating the pool water, although it is currently not operational. This system consists of six plate and frame heat exchangers and four pumps, but the piping to the dehumidification units for the heat recovery is valved off. There are also four natural gas fired roof top packaged units as well as 6 split system air handling units that provide additional heating and cooling to the other portions of the building. Controls All HVAC systems are controlled by nine thermostats throughout the building. Four thermostats, all of which are located in publicly accessible areas, are in lockboxes to prevent setpoint change. The remaining thermostats are in offices and the kitchen and are not in lockboxes. Of these thermostats, four are programmable, although they are currently not programmed. These are in the offices, men’s and women’s locker room, and kitchen. The other five thermostats are pneumatic. The mixture of control types does not allow for effective communication for building systems. Miscellaneous Loads The largest miscellaneous load at the Augusta Aquatics Center that is unique to swimming pools is the pool circulation pumps.

Utility Analysis The chart below shows the monthly electric usage (kWh) for the Augusta Aquatics Center during the baseline year (2018). A different baseline periods was used at this location as some of the mechanical equipment was not operable during the project wide baseline of October 2018 through September 2019. Thus, the baseline year of 2018 was chosen as this utility data is a better representation of normal operating conditions at the building. The energy usage at the Augusta Aquatics Center largely depends on the schedule of events. The loads within the building are going to greatly influence how long pieces of electric equipment, such as AHUs, PTACs, and pumps, are going to run. As seen in the chart below, there is a consistent baseload likely from the pool circulation pumps running 24/7 year-round. That being said, there are still seasonal trends present in the data noted by the decreased cooling loads in the winter which corelates with higher gas usage during these months. Conversely, electrical usage peaks in the summer when the DX cooling systems run for longer periods of time to maintain building comfort. 19 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Monthly electrical demand (kW), shown below, for the baseline year follow the same trend as the monthly electrical energy data for the same reasons discussed above. Monthly natural gas consumption follows a typical trend for a building with the same HVAC systems as Augusta Aquatics Center. As discussed above, gas consumption peaks in the months where the building requires heating. The small amounts of gas usage during the warmer months (May through September) is likely due to the building’s base natural gas load where a small amount of natural gas is used for domestic water heating. 0 20,000 40,000 60,000 80,000 100,000 120,000 140,000 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec CO N S U M P T I O N ( K W H ) Monthly Electrical Energy Consumption kWh Poly.

The roof is a flat membrane and in good condition. Mechanical Systems There are six variable volume air handling units total at the building, with two on each floor. AHU-4 and AHU-1 serve the first floor, AHU-2 and AHU-3 serve the second floor, AHU-5 serves the third floor, and AHU-6 serves the fourth floor. Each of these units has electric heat with cooling provided via chilled water. Chilled water is generated by two Trane water cooled centrifugal chillers. The chilled water loop is made up of two primary and two secondary chilled water pumps. Each chiller is paired with an induced draft open cooling tower located outside the building on grade. The condenser water loop is made up of two primary condenser water pumps. The Solicitor’s General Office must be cooled or heated 24/7 and is a small portion of the building. The chillers are not designed to operate efficiently at the extremely low levels of cooling load exhibited by the small portion of the building that is occupied when the remainder of the building is unoccupied. To overcome this problem, the building will install a small 60-ton chiller to serve this space to prevent 24/7 operation of the entire building mechanical system. The building also has one electric domestic water boiler. Controls The building uses a Reliable Controls BAS to control all mechanical equipment throughout the building. Miscellaneous Loads Given this building is a predominantly used as an office space and for court hearings, largest miscellaneous loads are from computers throughout the building.

Utility Analysis The chart below shows the monthly electric usage (kWh) for the Julian Smith Casino during the baseline year (October 2018 to September 2019. This profile is not consistent with mechanical systems having natural gas heating and electric cooling. Typically, electricity consumption spikes in the summer and drops in the winter. The profile below shows the opposite. It is possible a meter is missing, although unlikely as the energy consumption per square foot at this building (60 kBtu/ft2) is consistent for a building of this type. Given that the building is used as a rental facility, there may be more use during the winter than summer. This may also explain why there is a spike in consumption in October 2018. This spike consistent with consumption in October 2019 as well. Given that this facility is rentable, it is possible there are more events during this month, causing increased consumption. There are also data points missing in the utility data for the baseline period of June and July 2019, as well as June and July 2018. While the reason for this missing data is unknown, it is possible the building is not open during these months, or was not rented. Monthly electrical demand (kW) is shown below, for the baseline year. The demand profile at this building is flat. This is likely because the building run-time hours varies depending on the schedule of events.

The Multipurpose Room or the entire facility are available for rental. Utility Analysis The chart below shows the monthly electric usage (kWh) during the most recent year with complete data (October 2017 to September 2018). Data was not available for 2019. The electricity data shown below does not represent the complete electricity usage for McDuffie Woods Community Center. This building is over 15,000 square feet and the electricity usage at this location is low relative to building size. Thus, the utility baseline for this period was estimated based on usage at May Park and Warren Road, as show in the second monthly electrical consumption graph. These locations were used to estimate the baseline at McDuffie Community center because they have similar characteristics. The updated profile better matches the McDuffie Community center in terms of amount of consumption, but also overall shape given the building is cooled by split-systems and heated via a combination of gas furnaces and electrical resistance heat. The electrical resistance heat is what is responsible for the electrical energy consumption seen in the winter months outside of base and miscellaneous loads.

Utility Analysis The chart below shows the monthly electric usage (kWh) during the baseline year (October 2018 to September 2019). The overall shape of the polynomial regression line is consistent with buildings that have electric cooling and heating that is mostly gas, but the consumption is low relative to building size. Peaks occur during the summer due to the increased cooling energy use. Winter electricity usage seems unusually low, especially since the gym is heated with heat pumps and there are three systems with electric resistance heat in the community center building. This facility is likely missing data, or the meter is faulty. 200 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Monthly electric demand (kW) for the baseline year is shown in the chart below. Monthly electrical demand also peaks during the summer due to cooling, but is low in the winter, likely because of missing data. The chart below shows the monthly natural gas usage (therms) during the baseline year (October 2018 to September 2019). Monthly natural gas consumption increases in winter months and decreases to zero in summer months. The Kitchen has a gas water heater and gas-fired cooking equipment; hence, gas usage should not decrease to zero. This facility may be missing gas data, or the gas meter may be faulty. 0 2,000 4,000 6,000 8,000 10,000 12,000 14,000 16,000 18,000 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec CO N S U M P T I O N ( K W H ) Monthly Electrical Energy Consumption kWh Poly.

Included are all the applicable rates from Georgia Power Company and the Jefferson Energy Cooperative. Table 7 summarizes the tariffs that are applied to the base bill of Georgia Power customers. Tariffs applied to the base bill include Demand Side Management Commercial (DSM-C), Environmental Compliance Cost Recovery (ECCR), and Nuclear Construction Cost Recovery (NCCR). Note that DSM applies only to commercial customers, which are denoted in Table 5 by appending “-C” to the electric rate. For additional information on electricity rate structures, refer to Appendix 5. Table 6: Georgia Power Company – Base Bill Increase Fee Summary Base Bill Increase DSM-C ECCR NCCR Total 2.8801% 20.4194% 9.4596% 32.7591% Table 7 describes the Fuel Cost Recovery tariff, which is applied to electricity consumption for Georgia Power customers on all rate schedules except Time of Use – Energy Only (TOUEO) and Time of Use – General Service Demand (TOU-GSD).

Table 9: Georgia Power Company – Municipal Franchise Fee Total Bill Increase Inside City Limits Outside City Limits 3.0541% 1.1805% Buildings that receive electricity from Georgia Power are billed for electricity on several different rate schedules, including General Service (GS), Power and Light Small (PLS), Power and Light Medium (PLM), Time of Use – Energy Only (TOU-EO), Time of Use – General Service Demand (TOU-GSD), and Real Time Pricing – Day Ahead (RTPDA). Descriptions of each electricity rate schedule are included in the appendix. General Service is appropriate for buildings with low electricity usage and electricity usage less than 200 hours times billing demand. Power and Light Small is appropriate for buildings with a peak demand less than 30 kW and electricity usage of more than 200 hours times billing demand. Power and Light Medium is appropriate for buildings with a peak demand between 30 kW and 500 kW with electric usage of more than 200 hours times billing demand. Time of Use – Energy Only is appropriate for buildings with a peak demand less than 200 kW and electricity usage of less than 200 hours times billing demand or electric heat. The Augusta-Richmond Judicial Center and Charles B. Webster Detention Center are billed for electricity on Real Time Pricing (RFP) Day-Ahead. RTP billing is based on both actual electricity consumption and a historical electricity profile called Customer Baseline Load (CBL). These facilities have a contractually defined CBL. The CBL portion the bill for Augusta-Richmond County Judicial Center and Charles B. Webster Detention Center is billed on PLM. The customer is required to buy this power under a normal specified rate. However, if real used power is greater or less than the CBL power consumption, Georgia Power will bill or credit Augusta-Richmond County this power at hourly Real Time Pricing (RTP) rates. For these two facilities, the actual use power is generally more than the CBL amount. This is beneficial as the additional power billed on RTP rates is usually much cheaper than it would be if it were billed on the same rate as the CBL. Several buildings are missing information on their current electricity rate schedule. 3.3 NATURAL GAS RATES In Georgia, natural gas is deregulated. Atlanta Gas Light (AGL) owns and operates the distribution infrastructure for natural gas, while natural gas marketers sell gas to customers. AGL charges customers based on their Dedicated Design Day Capacity (DDDC), which is a measure of peak daily natural gas demand measured in units of dekatherms. AGL passthrough charges for commercial customers are summarized in Figure 1. Monthly passthrough charges are 1/12 of annual charges. 207 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Figure 1: Natural Gas Rate Structure – AGL General Gas Delivery Service The following tables describe the applicable natural gas rate schedules for each building described in Table 5. These charges are in addition to the AGL pass-through charges described above. Note that the energy rate for fixed pricing plans varies by the length of the contract and the date that the contract is renewed. The energy rate for fixed price plans shown below is based on a 12-month contract plan available on 9/30/2020. The energy rate for variable pricing plans varies based on the market rate for natural gas.

AUDIT METHODOLOGY 4.1 AUDIT OVERVIEW An energy audit is a systematic approach to problem solving and decision making. The primary goals of the audits for Augusta-Richmond County facilities were to qualify and quantify how the building energy systems are performing now, how that performance can be improved, and what the results of those improvements will be in financial and non-financial terms. To create a comprehensive and multi-faceted energy savings approach, Trane gathered industry experts with multiple different technology focuses, as well as tapping Trane’s own expert staff. This helped create a detailed plan with the lowest level of risk for final implementation. By using trusted industry partners Augusta-Richmond County can take comfort that estimated implementation plan, price and energy reduction potential are feasible and realistic. The following separate audits were completed to ensure success in this approach - Lighting Systems Audits, performed by Envocore - HVAC and Controls Audits, performed by Griffith Engineering Inc., and Trane personnel - Water Fixture Audits, Performed by Pedal Valves - Building Envelope Audits, performed by The Energy Partners - Solar PV Audits, performed by Radiance Solar 4.2 LIGHTING SYSTEMS ENERGY AUDITS Trane’s trusted partner Envocore, along with Trane personnel performed lighting audits on all facilities in the scope of this project. The procedure for performing the detailed lighting audit is to survey each room in each building so that the existing lighting system applications can be fully understood. With this information the current operating characteristics can be compared to the current requirements needed by the customer. Following this assessment, the appropriate fixture and lamp retrofit or replacement decisions can be made to reduce energy consumption, provide recommended light levels, and meet other customer requirements. The lighting audit takes into account the following:  Perform and provide the customer with a complete audit of all light fixtures in all identified facilities. The audit shall include the following data broken down on a room-by-room basis:  Representative light level readings (one of each typical type of room shall be measured)  Light fixture counts and detailed descriptions.  Typical hours of operation in hours/year.  Lamp quantity/fixture and watts/lamp.  Note major factors effecting lighting retrofit cost, including but not limited to A/B switching, emergency fluorescent ballasts that must be replaced, existing dimming controls, possibility of tandem wiring fixtures, etc.  Determine recommended lighting retrofits, incorporating:  Lighting retrofits to be performed on a room-by-room basis with a detailed description of all proposed lighting fixture retrofits.  IES recommended light levels in all rooms, unless directed otherwise by the end-user.  Reasonable effort in finding problems with the existing lighting systems, and recommend solutions.  Perform energy savings calculations on a room-by-room basis, incorporating:  Actual rate structures.  Energy savings in terms of kW and kWh, as well as dollars.  Hours of operation and kW for each fixture, before and after the retrofit.  Provide turnkey installation costs and savings for all buildings.  Should maps or floorplans be available, prior to the audit, a detailed mapping plan will be developed. This detailed mapping plan allows for a numbering system to be put into place where 214 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only each space or room on the maps are numbered and will match an ID # in the detailed room by room spreadsheet within the detailed lighting proposal. For this project a representative sample of existing fixtures were measured to determine existing or as is wattage levels. These wattage values were used to tune the savings calculations developed in the room by room audit spreadsheet. Pre-measurements were complete at the time of the lighting audit. During the installation phase a full scale M&V plan will be implemented which includes the post retrofit measurement of a statistically valid sample of all the lighting fixtures. These new values will be used to calculate the actual lighting savings. During the lighting audit the following options are considered for reducing lighting energy costs:  Regular Maintenance - A thorough lamp maintenance program can extend lamp life and improve lighting levels by up to 30%.  Lamp Replacement - Fluorescent lamps should be replaced at the end of their useful life (defined as 70% of the rated life), since lumens-per-watt rating starts to decline at this point, lowering overall light levels.  Lower Fixtures - Lowering ceiling fixtures to bring them closer to the workspace increases the amount of available light focused on the task. If the distance between fixture and work plane is 10 feet or more, further investigation may be required.  Repainting - Overall lighting efficiency is directly affected by the color of the ceilings, walls, equipment and other surfaces in the workplace. Selecting lighter, more reflective colors when repainting can enhance contrast and promote safety by increasing the amount of available light.  Daylighting - Installation of skylights in conjunction with automatic dimming devices can yield significant savings in some environments. However, the use of natural light from windows and skylights requires a thorough analysis, both from a lighting and heating/cooling standpoint. Consult the IES Lighting Handbook, 1984 Reference Volume, and 1987 Applications Volume for more information on this option.  Control Devices - The installation of various lighting control devices can reduce energy costs. Recent technological advances in industrial lighting system components and controls make it possible to reduce consumption significantly through scheduling and automatic control.  Convert to Energy Efficient Lamps - One attractive alternative for energy conservation is replacing existing fluorescent lamps with the new lower wattage energy efficient LED lamps. The existing lighting systems are described in Section 2 of this report, while a general description of the lighting ECM as a whole is contained in section 6, along with all applicable locations where this ECM is proposed. Appendix 1 is comprised of the line-by-line lighting audit. 4.3 DESCRIPTION OF HVAC AND CONTROLS SYSTEMS ENERGY AUDITS HVAC and controls audits were performed by Griffith Engineering Inc, an expert energy engineering firm, and Trane personnel. Trane local staff familiar with the Augusta-Richmond County facilities, and Corporate energy services staff helped develop the plan, pricing, and savings for these measures. A senior energy engineer visited each location in the scope of this project, to collect detailed information, both on building operation and installed equipment. During the audit, information recorded included hours of operations, building type, mechanical systems, lighting systems, as well as other additional information. This was used to determine baseline operation as well as to identify potential energy conservation measures throughout the Augusta- Richmond County’s buildings. The detailed energy audit referred to as an Investment Grade Audit (similar to an ASHRAE level II/III audit) requires further investigation resulting in a more comprehensive energy end use analysis. The detailed energy audit for Augusta-Richmond County included, but was not limited to:  Visual inspection and inventory of the buildings 215 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only  Construction details of the building envelope (e.g., walls, roof, windows, doors and related insulation values)  An inventory of the heating and cooling systems (HVAC) capacities and rated efficiency  Manual, timeclock or automated HVAC control methods  Service hot water systems  Investigation into operations and maintenance procedures, schedules, and typical building occupancy.  The cost analysis considers current energy costs, measure implementation costs and potential savings over time help to determine practicality and priority of ECM’s  Review of any upgrades since initial construction Once this information was collected at the various building Trane evaluated potential savings at each location as well as which building would require energy models to further evaluate savings opportunities. This will be detailed further in Section 6. 4.4 DOMESTIC WATER AUDITS Trane investigated the potential for implementing water fixture retrofits at Augusta-Richmond County facilities to reduce the water and energy utility use. However, since the utility is owned by the municipality, water costs were low enough that this measure was only deemed to make sense at the Charles Webster Detention Center. To investigate this opportunity, Trane teamed up with Pedal Valves, and expert water systems consultant. The water conservation audit included a detailed location by location inventory of all the water and water related infrastructure the Detention Center property. The information collected was used to analyze domestic water use, treatment, heating, and distribution throughout the property. The water systems engineers then proposed improvement to help reduce the facilities water use and energy consumption. Water modeling and proposal development utilizes various procedures and guidelines to calculate, establish, and quantify the utility savings resulting from sustainability projects surrounding water related utility and maintenance measures. All measurements and tests are conducted both during the audit phase and after construction is completed. All results are documented and incorporated into water utility modeling data and proposals. Water conservation is an essential part of sustainability projects, ensuring that our most precious natural resource is delivered in a clean, healthy, and efficient manner to everyone. With water rates climbing across the country at record levels, and with current water resources dwindling in many parts of the county, it is essential that everyone keeps water conservation in mind and is proactive about implementing ways to protect this most precious natural resource and everyone’s bottom line. 4.5 BUILDING ENVELOPE AUDITS The Energy Partners, Trane’s trusted building envelop consultant, lead up the building envelop audits into Augusta-Richmond County’s facilities. The building envelop encompasses the architectural systems in the facility to separate the building’s interior conditioned air from the exterior outside weather. For an energy audit, the primary focus is to ensure the architectural components (windows, doors, attics, wall insulation, etc.) tightly seal and insulate the building to reduce unneeded energy consumption from the HVAC systems. Additional benefits of tightly sealed buildings, such as improved air quality, improved occupant comfort, and reduced water intrusion are also considered. Trane had the energy partners perform building envelop audits on the majority of building in the scope of this project. At each location, deficiencies, such as poor air sealing around fenestrations (windows and doors), air leakage around architectural joints, and poor envelop insulation were observed and noted. The envelop engineers evaluated the feasibility, price, and energy savings associated with each deficiency in order to develop a comprehensive plan to save energy consumption for each facility. 216 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Section 6 had more detailed information on the proposed building envelop ECMs. Additionally, Appendix 4 has the detailed audit information on a building by building basis 4.6 SOLAR PHOTOVOLTAIC AUDIT Trane AND PARTNER Radiance Solar has identified locations that would benefit from the addition of a photovoltaic (PV) solar array. The PV solar audit focused on buildings that have both the available space for the array as well as a utility profile that lends itself to optimal usage of the array. The size of the array is dependent on its energy capacity, which needs to be sized with the utility profile taken into consideration. When auditing a building for a suitable PV solar array location, it is important to take note of not only the square footage needed for the array, but also any existing or anticipated obstructions that can shield the array from the desired solar energy. Locating an array on or near ground level involves consideration of shading from nearby buildings and landscaping. Appraising opportunities for a roof-mounted PV solar array reduces some of the potential shading from buildings and landscape but does not eliminate them. Roof- mounted arrays are also evaluated based on the roof’s slope and orientation, which has an impact on the amount of solar energy available at different times throughout the day and the year. The audit also took into consideration the utility profiles of buildings with potential for arrays. In most situations, the best use of a PV solar array is to fully utilize its energy potential throughout the year. The benefits of the array should be able to be used by the building for as much of the year as possible. If the energy production of the PV solar array exceeds the building’s energy demands, this excess energy may be sold back to the utility, though this is typically at a lower rate and is less desirable than direct utilization of the energy at the building. It is therefore important to coordinate the capacity of the array with the utility analysis to obtain an optimized energy solution from the array. The PV solar audit also investigates how the array will be interconnected into the building’s electricity distribution and any potential connections to allow for selling energy back to the utility grid. The audit will focus on any modifications that are needed to the existing electrical system to account for a new PV solar array. Section 6 had more detailed information on the proposed solar PV ECMs. Additionally, Appendix 5 has the detailed solar PV information from Radiance Solar. 217 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only 5. BASELINE ANALYSIS METHODOLOGY 5.1 BASELINE OVERVIEW This “baseline” as defined here is a period of energy use over a 12-month period, which properly represents existing building systems and operation during the heating and cooling season. The development of energy baselines for this project is an important exercise in performance contracting is this baseline will be the reference metric for the performance of the project in each guarantee year. Energy consumption for each building, each year, is compared to this baseline energy consumption. To develop the baselines, Trane collected historical electricity, natural gas, and water bills for the recent few years (wherever available). Trane’s goal in establishing a baseline energy consumption is to have a monthly energy/water consumption profile that is representative of normal facility operation. Given the extraordinary upheaval the COVID-19 virus has had on all public facility operations, it was determined that this baseline period had to end before March 2020, when major disrupters started happening. In Addition to COVID-19 concerns, Trane wanted to select data that was both recent enough to be representative of current building operation and equipment, and mostly complete for all facilities in this project. Due to the data available, and these noted concerns, utility data from the 12-month period of October 2018 through September 2019 was chosen as the foundation of each building’s energy use baseline. Each building’s utility profile is investigated to identify potential outliers or errors that need to be addressed. For Augusta-Richmond County, there were few situations where a billed data point was “corrected” as the billing data was reliable. However, the analysis of each building’s energy profile also helps Trane understand system energy use and potential for energy improvement. Figure 4.1 shows an example of a utility analysis for electric and natural gas consumption at Charles B. Webster Detention Center.

These benchmark metrics are then used to compare the building’s energy usage to that of similar buildings in the same region with similar principle building activities. Electricity and Natural Gas data is normalized into a single kBtu/ft2 index. When totalized for all Augusta-Richmond County buildings yielded an overall value of 94 kBtu/ft2 which when compared to the U.S. Department of Energy – Commercial Buildings Energy Consumption 2012 Survey (CBECS) average of 67 kBtu/ft2, indicates that some energy conservation measures (ECMs) opportunities certainly exist. The table below shows the pertinent utility data for the Baseline Year (October 2018 through September 2019) on a building by building basis for calculating EUI and ECI (Energy Cost Index) for this period. While it might be obvious, water consumption and associated cost are not included in the calculation for EUI and ECI, because water is not directly associated with energy usage. 0 200 400 600 800 1,000 1,200 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec DE M A N D ( K W ) Monthly Electrical Demand kw Poly.

During the initial audit phase, several interviews were conducted with Augusta-Richmond County’s personnel to get a clearer understanding as to what type of activities occur within the buildings. The Trane team classified the Augusta-Richmond County facilities in to building types as noted in the table below. These classifications were used when running simple analyses on the facility utility data (listed in Section 2) to ensure baseline utility profiles were accurate given the building’s type and use. These classifications were also used to ensure modeling of applicable buildings was accurate.

ENERGY CONSERVATION MEASURE EVALUATION 6.1 OVERVIEW OF ECMs CONSIDERED Trane is proposing ECMs for 89 separate facilities in this project. The ECMs, which will result in both annual energy and cost reduction, can be divided into 6 categories. These categories are: 1) Lighting Fixture and System Retrofits and Improvements 2) HVAC (Heating Ventilation and Air Conditioning) System Improvements 3) Controls (for building mechanical and electrical systems) Improvements 4) Water (domestic) Fixture Retrofits and Improvements 5) Solar PV installations 6) Building Envelope (Walls, Windows, Doors, Roof) Improvements Details on these ECMs is presented in this section. The ECM Matrix below shows which ECMs are proposed in each building surveyed during the Detail Energy Audit. For detailed information regarding modeling methodology for these locations and ECMs, refer to Appendix 6.

Unless a building has been built or renovated in the past few years, it is common to find extensive use of fluorescent, metal halide, and incandescent fixtures throughout the building. These older lighting technologies are a product of their time and often remain without intentional replacement. Older lighting technologies require more wattage to produce the same amount of light as LED fixtures. This results in more electrical energy consumption for lighting systems and also a higher heat output from the lamps which raises HVAC cooling costs. For this measure, existing fluorescent, metal halide and incandescent lighting fixtures will be replaced/retrofitted with new LED tubes, lamps, retrofit kits, and/or fixtures. This will greatly reduce the energy required to illuminate the building. Additionally, cooling systems will have to run less often to offset the heat generated by the lighting. There are several additional benefits to LED lighting technology. LED lighting has longer burn hour life, faster on/off response time, and easier dimming capabilities compared to fluorescent and incandescent technologies. Because LED light fixtures have longer burn hour life, this will reduce the material and time cost of replacing burned out lamps. This is especially advantageous in building areas with high ceilings, such as high-bay areas, where the maintenance costs associated with lamp replacements includes renting or obtaining lifts to reach the fixtures. Currently, a wide variety of fluorescent, incandescent, metal halide, and other types of lighting technologies exist throughout Augusta-Richmond County’s facilities. The specific retrofits, replacements, or upgrades for this building are described in Appendix 1, the Lighting Room by Room audit worksheet. In this table the proposed descriptions and quantities are given for each of the rooms listed. Short summaries of existing lighting equipment for each building can also be found in section 2. Overall, the customer will receive the following benefits from the lighting upgrades:  Energy savings  Maintenance cost savings  Improved aesthetics  Better security and employee safety  Environmental sensitivity / ability to help your organization improve its sustainability  Tenant satisfaction, including potentially improved health and efficiency Affected Locations and Scope 229 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Below is a list of buildings that are in scope for energy savings associated with lighting.

In some cases, new cooling towers will be installed to accompany these new chillers. The existing chillers to be removed as part of this measure are older, degraded efficiency chillers. These machines provide chilled water to coils in air handling units and fan coils to cool the building. Cooling towers provide condenser water which accepts heat rejected from a chiller and transfers it to the environment (outdoors) via evaporative cooling. Over time, chillers lose efficiency due to fouling, which is the build-up of contaminants on the heat exchanger surfaces. Chillers also lose efficiency as they age due to corrosion and typical wear on moving parts. Additionally, the chillers being replaced are 20 years old or older and nearing the end of their useful life. Replacing them in this project will eliminate capital replacements costs in the near future. The new chillers that are installed will provide a higher IPLV (integrated part-load value) than the existing chillers they will replace, thereby providing cooling operation energy savings. The new chillers also support variable flow through the evaporator barrels, which allows pumping systems to be converted to lower power consuming variable flow set-ups. Also, with the newer on-board controllers, Tran can employ chiller/tower optimization control Affected Equipment This measure is proposed for two locations: The Augusta Municipal Building, and The Charles B. Webster Detention Center. Note that the cooling tower replacements will only occur at the Detention Center’s older plant, as the towers for the Detention Center’s newer plant, and the towers at the municipal building are in decent shape. Below is a list of equipment affected by this measure.

To see detailed methodology for savings calculations for this ECM, refer to the Trace 700TM Methods of Estimating Savings Appendices. Existing and Proposed Value Assumptions Savings were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For a chiller/cooling tower retrofit, the key variables to be changed are the cooling efficiency and the cooling tonnage. The table below shows the key values that were modified to calculate the energy savings for this measure. Table 26: Chiller/Cooling Tower Retrofit Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Municipal Building Full Load Chiller Efficiency 0.6711 kW/ton 0.5418 kW/ton Chiller Tonnage 205 tons 250 tons Charles B Webster Detention Center Full Load Chiller Efficiency 0.72 kW/ton 0.5886 kW/ton Cooling Tower Fan Control Constant VFD w/ 10°F ΔT A variable primary, variable secondary flow CHW retrofit will be implemented in several buildings where traditional primary/secondary flow systems exist. In these systems, constant volume flow primary chilled water is currently in place. This is usually due to older chillers being unable to support variable flow through the evaporator barrels. With newer chillers the existing pumping systems can be easily converted to variable flow, using the existing pumps. Variable primary, variable secondary flow chilled water systems are configured to use the existing separate primary and secondary loops, implying that two sets of pumps remain to move chilled water. One set of pumps (primary loop) moves water through the chiller(s), and another (secondary loop) moves chilled water through the distribution system in the building. New Variable speed/frequency drives (VSD/VFDs) will be installed to adjust and control pump speed. The existing constant volume pump motors will be retrofit with new grounding rings or replaced with new inverter duty motors to support new VFDs. Chilled water coils 6.3.2 Variable Primary Variable Secondary Pumping / VFDs 235 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only on air handlers with existing three-way (constant flow) chilled water valves will be retrofit with new two-way chilled water valves as part of this work. In a variable primary, variable secondary system, and flow meter is installed on the primary flow bypass. The controls system uses this to help match chiller evaporator (primary) flow rate to system flow demand as close as possible. This reduces the average chiller evaporator flow rate during part-load cooling conditions. Reduction of chilled water primary flow rate leads to hydraulic (pumping) energy savings during these conditions. In addition, reduced chiller evaporator flow (primary loop) at a given load serves to improve chiller operating efficiency at that load. This measure requires more complicated controls algorithms than traditional variable primary system, which require only one set of primary pumps for the entire system. But if designed and controlled properly, both types of pumping system use similar amounts of energy. However, it is much cheaper to retrofit existing primary/secondary systems to this type of all-variable pumping system, as new pumps and piping modifications are not needed. For this project, the Augusta Municipal Building and the Augusta Richmond County Judicial Center already have variable flow secondary systems. For these buildings, only the primary loop must be converted to variable flow. For the Charles B. Webster Detention Center, both the primary and secondary loop for the old chiller water plant are constant volume. At this facility both loops will be converted to variable flow and AHU chilled water coils will be replaced with 2-way valves.

To see detailed methodology for savings calculations for this ECM, refer to the Trace 700TM Methods of Estimating Savings appendices. Existing and Proposed Value Assumptions Savings were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For the variable primary variable secondary pumping, the key variables to be changed are the pump power curves. For the existing systems, constant volume pumps were used. With constant volume pumps, the pump power does not change with load on the system. For the proposed case, variable speed pump power curves were used. These curves have a roughly cubic power reduction as load decreases. At the noted minimum speed the pump curves flatten, having roughly constant power for all loads below the load when the pump reaches minimum flow. The table below shows the key values that were modified to calculate the energy savings for this measure.

Water side economizers typically consist of a plate and frame heat exchanger which transfers heat from a chilled water system to a cooling tower water system during these favorable ambient conditions. Tower free cooling water-side economizer operation saves energy by allowing the cooling tower water system to extract thermal energy from the chilled water system without mechanical (chiller) cooling operation. This project will recommission a couple of existing tower free cooling water-side economizers, thereby maximizing their operation during periods when ambient wet bulb temperature is low (cool & dry time periods).

For recommissioning the waterside economizer, the key variables to be changed are the availability of the free cooling and adding in the pump power necessary for operation of the economizer. The table below shows the key values that were modified to calculate the energy savings for this measure. Table 30: Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Municipal Building Free Cooling Type None Plate and Frame Free Cooling Pump Power None 4.30 kW This measure proposes to replace existing DX equipment which is at or nearing the end of its predicted useful life. Direct expansion (DX) air conditioning equipment is the technical name for typical residential and small commercial style rooftop units and split systems. Many Augusta facilities are cooling and heated with these systems. DX systems consist of a refrigerant loop, in which the refrigerant is compressed and expanded at different points of the loop to transfer thermal energy. Typically, a refrigerant coil is placed directly in the supply air stream, where the refrigerant absorbs thermal energy as it evaporates and expands. Thermal energy is rejected at a compressor, where the refrigerant is compressed and condenses, rejecting the heat that was removed from the supply air steam. Over time, HVAC units degrade in operational efficiency as coil surfaces oxidize on the exterior and sometimes scale on the interior which reduces heat transfer efficiency. The moving mechanical components also wear, which further reduces the operational efficiency of the equipment. The new equipment will be installed in place of the existing equipment, including providing new refrigerant line sets for all split systems. Additionally, older DX equipment uses R-22 as its refrigerant, which has been phased out in favor of newer refrigerants with lower adverse environmental impact. Because it has been phased out, R-22 is far less available, meaning increased maintenance costs if additional refrigerant is required. Existing refrigerant will be handled and disposed of in a manner consistent with local environmental requirements. 6.3.4 DX Unit Retrofits 239 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Affected Equipment Table 31: DX retrofit Affected Equipment Building Qty Tag Equipment Manufacturer Model No. Serial No. Unit Size Date of Manufacture/Age of Unit Blythe Community Center 1 OHP-1 Condensing Unit Trane TWA060 P354D491F 5 ton 1999 Blythe Community Center 1 IHP-1 Split System AHU Trane TWE060C15FD0 P35535G1V 5 ton 1999 Blythe Community Center 1 OHP-3 Condensing Unit Trane TWA030 P352EC3CF -

To see detailed methodology for savings calculations for this ECM, refer to the Trace 700TM and Spreadsheet Methods for Estimating Savings appendices. Note that savings for DX equipment retrofit at the Augusta Aquatics Center are not included in this report, as these were handled under a separate contract. Existing and Proposed Value Assumptions Savings were calculated based on changing key inputs and assumptions for this measure. The key assumption for this measure was the average heating and cooling efficiency of the DX equipment. The table below shows the key values that were modified to calculate the energy savings for this measure. To get the numbers below, Trane used standard methods. The existing efficiency for equipment was calculated from the original manufacturer’s data. For cooling, this was the reported SEER or IEER. In some cases, only EER was report and it was converted to SEER with the following formula. 𝑆𝐸𝐸𝑅=𝐸𝐸𝑅/.875 If no SEER, IEER or EER value from the manufacturer could be found, the 90.1 minimum efficiency from the appropriate year was used. For heat efficiencies, the listed manufacturer’s value was used. For Heat pumps, a HSPF or COP at 47F was used. If this was not available, the 90.1 minimum value from the appropriate year was used. Finally, to all original efficiencies were degraded by a consistent annual value. For cooling and heat pump heating, this was 1% per year. For gas heating this was 0.5%. Electric strip heating efficiency was not degraded. For all “proposed” efficiencies, the proposed equipment manufacturer’s efficiency was used.

When a pumping system is designed, the pump is selected based on a design flow and an estimated pressure drop through the distribution piping system. Often times, the design engineer will add one or more safety factors to their pump selection, which allows for the potential of additional pressure drop in the system due to unforeseen field conditions. Once the system is installed, the flow is typically balanced for the actual installed conditions. A common method for balancing constant flow pumps is to partially close triple duty valves, or balancing valves, introducing additional pressure drop. This shifts the pump along its performance curves until it reaches the desired flow, but doesn’t reduced pump speed or power draw very much. 6.3.5 Add Condenser Water Pump VFDs 244 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Instead of using balancing valves, A VFD will be installed on the pump motor and used to reduce the sump speed in order to balance the constant volume system to its design flow. The VFD will allow the pump motor to operate at a more efficient point on the performance curve, as well as reducing the overall power draw of the motor by operating at a lower speed.

Filters are a required AHU component throughout any facility for cleanliness and IAQ concerns. Newer technology in filters can give excellent performance with regards to particle filtration with less pressure drop than older technology. Electrostatic filter technology combines the benefits of passive filtration with those of electro-static attraction. A charge is applied to the filter, which polarizes the media and the surrounding particles. This causes particles in the air to be attracted to the filter and stick to it, including very fine particulates as well as gas contaminants which traditional air filters cannot capture. Due to this, the filters don’t need to be as invasive to the airstream, and there’s less pressure drop across the filter. For more information on Dynamic Air Filtration, refer to Appendix 9. 246 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Affected Equipment Table 36: Existing and Proposed Values Building Tag Equipment Model No. Serial No. Augusta-Richmond County Judicial Center AHU-1 AHU MCCB050 K09G15687 Augusta-Richmond County Judicial Center AHU-2 AHU MCCB066 K09G15696 Augusta-Richmond County Judicial Center AHU-3 AHU MCCB066 K09G15705 Augusta-Richmond County Judicial Center AHU-4 AHU MCCB066 K09G15713 Augusta-Richmond County Judicial Center AHU-5 AHU MCCB066 K09G15730 Augusta-Richmond County Judicial Center AHU-6 AHU MCCB050 K09G15685 Charles B.

Webster Detention Center Facility improvement measures (FIMs) are measures intended to improve the operation and value of building systems but are not associated directly with energy savings. Trane has been requested by the facility staff to replace 11 air handlers in pod “E” at the Charles B. Webster Detention Center. These eleven air handlers are named “AHU E1”, though “AHU E11”. The air handlers are aging, and the facility has been planning replacement of them. The upgrade of the building automation controls provides a cost effect opportunity to perform this work. The new Air Handlers will be designed to match original facility specifications barring any space changes or previous deficiencies revealed during the design investigation. While the new AHUs will have upgraded controls, cleaner heating and cooling coils, and potentially more efficient motors, savings from this measure are assumed to be small and were not calculated as part of this project.

There are no savings associated with this measure, and thus there is no calculation methodology. Existing and Proposed Values This is a like for like replacement of existing AHUs. There will be no significant changes in efficiency between the existing and proposed replacements. FIMs are measures intended to improve the operation and value of building systems but are not associated directly with energy savings. In the Judicial Center, there is an energy savings measure for retrocommissioning the controls system there. As a part of that ECM, there was setback being taken for all areas except the Solicitor’s 24/7 spaces. However, it was said that the current chillers cannot handle setback occurring everywhere due to issues with the chillers during low loads. As a result, this FIM was developed to help facilitate being able to setback the temperature in those spaces. There will be a new 60-ton auxiliary air-cooled chiller that will handle cooling during setback/low load conditions. The existing controls shall be updated to allow for this auxiliary chiller mode when at low loads. In this mode, the existing chilled water control valve shall close, to direct chilled water flow from the new air-cooled chiller to AHU-3. It is very important to note that this upgrade is required to realize the full savings potential from retrocommissioning measure for the Judicial Center. Affected Equipment All controls equipment, AHUs, and chiller/cooling equipment is affected by this measure. FIMs are measures intended to improve the operation and value of building systems but are not associated directly with energy savings. This measure proposes to install bipolar ionization units as a means to improve indoor air quality. Bipolar ionization works to clean the air by producing ions, which induce the particles in air to clump together and become caught in the filters. This also helps reduce odors and airborne pathogens while simultaneously cleaning the coils of HVAC equipment. The improved indoor air quality has also been shown to lead to greater levels of occupant attentiveness, productivity, and comfort, and can reduce the number of airborne infectious disease particulates, including SARS-CoV-2 which causes COVID-19, from the air.

The Tracer ES will reside on Trane’s “Trane Connect” Cloud Based Servers via locally installed digi routers in each facility. This network will receive and store building data that is being gathered from each individual building’s system level controllers. The Tracer system will also consist of a centralized and interactive graphical user interface. In addition to the centralized user interface, the Tracer ES offers remote access via the Web as well as mobile devices, allowing the Augusta-Richmond County enterprise of buildings to be effectively managed from nearly any location by authorized facility’s staff. At the individual building level, Trane will be providing Tracer System Controllers (Tracer SC’s). These controllers will be the “brain” of each building in terms of building automation. Like the Tracer ES, each Tracer SC will offer remote access via the Web as well as mobile devices. At many of the smaller sites, the Tracer SC will be paired with a Tracer Concierge touchscreen display, offering the end user with the ability to toggle set points with the touch of a finger. End devices and unit controllers in each building will ultimately tie back to that building’s Tracer SC via wireless and/or wired communications. The Tracer SC will also offer device graphics and floor plan graphics, which will aid facility’s staff in physically locating issues that need to be addressed. Trane controls systems will enable the Augusta-Richmond County Facilities Team to efficiently manage buildings from nearly anywhere with one system, leading to high performance and consistent comfort in each building. The centralized interface will allow facilities staff to monitor buildings across Augusta- Richmond County from a single access point. This will reduce response time to possible issues, often without having to spend time traveling from building to building. Staff can manage and respond to alarms, change set points, and modify schedules conveniently from their computers. Many operational improvements will also be seen in each individual building. Each building can be custom scheduled to match building occupancy so that mechanical equipment runs only when it is needed. This 250 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only leads to energy savings, extended system life, and reduced lifecycle operating costs. Alarms will be sent to established facilities staff, informing them of any issues that need to be addressed in the building. This real time data helps reduce response time and enables predictive maintenance. Lastly, Trane control systems offer graphics that allow staff to easily navigate between equipment and find the root cause of a problem leading to greater occupant comfort. Augusta Richmond County’s facilities can be divided up into two main categories of solution.  Complete Retrofit of existing Controls with new Trace SC+ and Retrocommissioning  New Air-Fi Trane Concierge Building Controls Additionally, the addition of “Demand Control Ventilation” at the Judicial Center and “Kitchen Demand Control Ventilation & Exhaust” at the Detention Center were evaluated separately. The following table shows where each of these measures will be implemented.

Webster Detention Center) with older DDC controls will be upgraded to New Trane systems and interconnected back to the central Tracer ES. Additionally, Trane teams will provide a full retro-commissioning of air-side and water-side systems, replacing malfunctioning hvac equipment. All controls equipment in this building will be replaced or upgraded as part of this retrofit. The new system will be programed with a suite of energy savings strategies to reduce energy consumption of HVAC systems. The following strategies will be used - HVAC system scheduling and setback - Temperature setpoint optimization - Optimum Start (morning warm-up) - Static Pressure Reset - Airflow/Ventilation Improvements - Fan Cycling Optimization - Chiller plant/Cooling Tower Optimization - Condenser Water Reset While this controls upgrade and Retrocommissioning (RCx) effort is described as one measure, there are a variety of upgrades that will be made specifically due to RCx efforts. Retrocommissioning is being performed in all facilities to identify and correct potential unknown operational issues with hvac and controls equipment. However, Trane is already planning for a number of known issues included for the Judicial center, identified by Trane personnel. The judicial center was observed to have several issues resulting in significant and excessive energy consumption. Over the years, issues with the system have resulted in the operations staff needed to over- ride original controls algorithms and set to the systems into manual operation. Some of these issues are the result of broken or malfunctioning equipment, and some of this is due to initial control sequences not being able to handle the use of the facility. By replacing the controls and malfunctioning air-side devices, the remaining equipment will be able to operate much more efficiently. Below are lists of the various upgrades that compromise the RCx efforts at the Judicial Center specifically. While these are listed individually, this it to provide clarity on what each of these upgrades accomplishes. Savings for each of these upgrades cannot be evaluated on an individual basis. Savings will be one value associated with this ECM. It should be noted that a recent project was undertaken by Trane at the Judicial Center to address operational and health issues on the 4th floor and with some other AHUs. Since the impact of these 6.4.1 New Tracer SC + Building Automation System w/ Retrocommissioning (RCx) 252 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only upgrades is not represented in the baseline utility data, a baseline adjustment was taken for these measures before applying savings for improvements made with this project. Strategies were divided into baselines adjustments and savings measures Baseline Adjustment Strategies (Judicial Center only) - Chiller Leaving Water Setpoint Adjustment - Increase AHU Outside Air Flow - Set AHU Cooling Discharge Air Temperature - Balance Return Air Energy Savings Controls & RCx Strategies (Judicial Center Specific) - Reprogram AHU K Factors - Chiller plant/Cooling Tower Optimization - HVAC system scheduling and setback - Temperature setpoint optimization - Optimum Start (morning warm-up) - Replace Malfunctioning VAV boxes Calculation Methodology All savings for this measure at all three buildings were calculated in Trane Trace 700. Baseline Adjustments (Judicial Center Only) The Augusta Judicial Center has several energy savings opportunities that will be realized with this measure. However, a few of the problems that were found in the audit are building air quality issues and need to be addressed as part of the project. However, these issues do not result in energy savings, and actually will result in more energy consumption. While some of these issues have been recently addressed, the historical utility data used for this project’s baselines does not represent operation after these changes were implemented, nor future needed changes. To account for this, Trane is taking a baseline adjustment to account for the additional energy consumption needed to address these issues. This was calculated in the Trane Trace 700 energy model. This means that the original energy model was calibrated first to the utility data, and then the adjustments were made to the model that account for these air quality changes. This accounts for the extra energy that these changes will make. Some of this work is currently underway and being corrected outside of this project, specifically fixing emergency issues with the 4th floor AHU. Correcting these issues provides energy savings but is being done outside of the project and hence was included in the baseline adjustment. Chiller Leaving Water Setpoint Adjustment (Baseline Adjustment) This measure involves changing the chilled water leaving the chiller to 42°F. Currently, the chilled water temperature is higher than that and the building is experiencing humidity issues as a result. This means that the chiller will be dehumidifying the air more effectively, but it will consume more energy to do so. This measure also helps facilitate another measure, Set AHU Cooling Discharge Air Setpoint. This is a retroactive measure to improve air quality in the building and will not result in energy savings. Existing and Proposed Values Calculations were made based on changing key inputs and assumptions from an existing value to a proposed value. For the chiller leaving water setpoint adjustment, the key variable to be changed was the chiller efficiency. The table below shows the key values that were modified to calculate the energy consumed for this measure. Table 40: Existing and Proposed Values 253 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Building Name Input Name Existing Value Proposed Value Augusta Richmond County Judicial Center Chiller Efficiency 0.64 kw/ton 0.66 kw/ton Increase AHU Outside Air (Baseline Adjustment) Currently, half of the Air Handling Units in the building are not providing the appropriate amount of outside air to the building based on their original design values. This can cause unwanted smells and odors to linger in the building. Increasing the amount of outside air entering the building will help resolve those issues. This will cause an increase in energy consumption due to the building having to condition more outside air than it was before. This Affects AHUs 1, 3 and 4. AHU-5 was also found to be providing too much OA, which was reduced in this measure. This will save energy for AHU-5 but was included in the baseline adjustment, in order to be consistent. This is a retroactive measure to improve air quality in the building and will not result in energy savings but consume more energy. Existing and Proposed Values Calculations were made based on changing key inputs and assumptions from an existing value to a proposed value. For the chiller leaving water setpoint adjustment, the key variable to be changed was the chiller efficiency. The table below shows the key values that were modified to calculate the energy consumed for this measure. Table 41: Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Richmond County Judicial Center AHU 1 OA Value 0.045 cfm/sqft 0.16 cfm/sqft AHU 3 OA Value 0.099 cfm/sqft 0.144 cfm/sqft AHU 4 OA Value 0.044 cfm/sqft 0.129 cfm/sqft AHU 5 OA Value 0.217 cfm/sqft 0.149 cfm/sqft Set AHU Cooling Discharge Air Setpoint (Baseline Adjustment) This measure involves changing the air handling unit supply air temperature to 55°F. Currently, the supply air temperatures are set manually, and several of them are set to higher than 55°F. This means that the air is not getting to a low enough temperature to dehumidify properly. Overall, this will consume more energy to properly dehumidify the air. This measure will affect all 6 main air handlers. This is a retroactive measure to improve air quality in the building and will not result in energy savings but consume more energy. Existing and Proposed Values Calculations were made based on changing key inputs and assumptions from an existing value to a proposed value. For changing the AHU cooling discharge setpoint, the key variable to be changed was the cooling supply air temperature. The table below shows the key values that were modified to calculate the energy consumed for this measure. 254 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Table 42: Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Richmond County Judicial Center AHU 1 Cooling Supply Air Setpoint 58°F Set all cooling supply air temperatures to 55°F.

As well, the supply air temperature is set to 63°F, which is too high to provide humidity. The setpoint will be set to 55°F with the Set AHU Cooling Discharge Air Setpoint part of this measure, but also the return air damper will be fixed so that it is automatically controlled. This will allow the economizer to function properly. This part of the measure produces energy savings, but it is already being done as part of another project so needs to be included in the baseline adjustment for the energy model. Existing and Proposed Values Calculations were made based on changing key inputs and assumptions from an existing value to a proposed value. For changing the balance air return, the key variable to be changed was the economizer availability. The table below shows the key values that were modified to calculate the energy impact for this measure. Table 43: Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Richmond County Judicial Center AHU-6 Economizer Availability 50% 100% Controls Improvements HVAC System Scheduling and Setback (All facilities) These three Augusta-Richmond County buildings are conditioned at the same space temperature set point on a 24/7/365 basis even though parts of these buildings are occupied only a portion of the time (Monday – Friday daytime hours for example). Scheduled HVAC setback turns off or sets back HVAC systems during unoccupied times and is the controls measure which will provide the greatest quantity of energy savings. This ECM involves implementation of space temperature set point reset / setback schedules for each building area and system which does not exhibit constant occupancy. Humidistats will also be incorporated to initiate air-conditioning system operation override, as needed, to prevent excessive relative humidity during unoccupied time periods. Existing and Proposed Values Savings were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For the unoccupied time period HVAC setback measure, the key variables to be changed were the occupied versus unoccupied schedules and unoccupied setpoint for HVAC equipment. The tables 255 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only below shows the setpoints and schedules that were modified to calculate the energy savings for this measure. To see existing occupancy schedules by location, refer to the building descriptions in Section 2. Schedules in Section 2 represent the time the buildings are occupied versus not. This is typically different than the schedule for when HVAC equipment is operational, as often buildings are either pre-cooled or pre-heated prior to the arrival of occupants. Below are the proposed operating schedules.

This prevents occupants from using extreme temperature settings and also reduces the potential for adjacent spaces within the building to be “fighting” each other. It is believed this is happening currently at the Municipal Building, where one spaces cooling thermostat settings cause the adjacent spaces to go into heating and the systems to fight for temperature control. Setpoints will be optimized for all buildings in this scope. Existing and Proposed Values Savings were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For the setpoint optimization measure, the key variables to be changed were the cooling and heating setpoints. The table below shows the key values that were modified to calculate the energy savings for this measure. Periods when the building is not occupied are proposed to have unoccupied setback to produce additional savings. See more detail about this measure in the section below. Table 53: Occupied versus Unoccupied Cooling and Heating Setpoint Values State Cooling Setpoint Heating Setpoint Occupied 72°F 70°F Unoccupied 82°F 60°F Optimum Start (All Facilities) Optimum start is also a controls optimization measure in scope for this project. This measure applies to any air-side system at the three facilities that are scheduled unoccupied for some period of time. Often, schedules are started a couple hours early to ensure the building warms up or cools down to the proper temperature before occupants get to the building. However, this is often over-aggressive and causes systems to run longer than needed. 257 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Optimum start is a control measure designed to automatically adjust the start time of a space conditioning system each day, based on space temperature and outside air temperature. The intent is to bring the space to desired occupied temperature levels right at the beginning of scheduled occupancy. By monitoring warm- up times for each system, the controls system learns to stat the warm-up at the exact right time to ensure building temperature meets the setpoint when the building goes occupied. This eliminates over-aggressive warm-up times. Existing and Proposed Values Savings were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For the optimum start measure, the key variable to be changed is the start time of the equipment. Given the nature of this measure, the proposed start time will vary. The table below shows the key values that were modified to calculate the energy savings for this measure. Table 54: Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Municipal Building FCUs w/ ERVs, AHU-2, Chamber FCUs n/a (24/7 run time) Active optimum start Charles B.

Webster Detention Center only. Static pressure is the pressure or resistance a fan must overcome to move air through ducts as needed for heating, ventilation, and cooling. Components such as coils, filters, diffusers, etc. can increase the resistance in a system. To overcome this resistance, fans produce enough pressure to push airflow to conditioned spaces. In a VAV systems, fan speed is typically controlled to maintain a constant static pressure under all conditions. This fan speed is typically determined as the minimum pressure needed to move air to the farthest point in a system to meet design conditions. Thus, static pressure and airflow are the main driver of an energy consumption in a VAV system. In a static pressure reset strategy, the minimum pressure is adjusted or reset at regular intervals to only be as high as needed to satisfy the zone of highest airflow demand. Fan speed is adjusted to meet this lower pressure set point. This reduction in pressure is proportional to the reduction in fan horsepower required. Thus, reduction in the pressure set point reduces the fan speed, and subsequently fan energy consumption.

The Augusta Municipal building has dedicated ventilation units that provide outside air for each floor. These units’ pre-condition the outside air and blow it into the return-air plenums for each floor. To ensure that the ventilation air is properly de- humidified, the ventilation units cool all the air to a dew point of 54F. However, to avoid potential condensation in the fresh air ductwork and the return air plenum, the air is then reheated to 65F. This is likely more reheat than is needed to prevent condensation. Trane is proposing to reduce the reheat setpoint to 62F. This is a small change, but it will have a large impact on energy consumption. This change will be made on fresh air units at the Municipal Building. Existing and Proposed Values Savings were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For the airflow/ventilation measure, the key variables to be changed were the occupied versus unoccupied schedules for ventilation. The table below shows the key values that were modified to calculate the energy savings for this measure. Table 55: Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Municipal Building AHU-2, Chamber, FCUs Available 100% Occupied 7a – 6p: 100% Unoccupied: 6p – 7a: 0% Augusta Municipal Building Dedicated OA heating setpoint 65F 62F Fan Cycling Optimization (Fan coils at the Municipal Building) This measure applies to the Augusta Municipal Building only. There are many fan coil units (FCUs) throughout the entire building. Air handling units and fan coil units help regulate temperature of one or more spaces by circulating air with a fan. These units currently do not cycle the fan off, meaning the fan is constantly running, regardless of building operation. This is done to ensure fresh air is brought into the building. However, for the municipal building, a separate fan powered system brings fresh air into the plenum and the fans could cycle some and still provide this to the spaces effectively. This strategy here is to cycle the non-ventilation system fans based on whether there is a call for cooling or heating in the space. An override will also be programmed into the fan coil controllers ensuring the systems cycle on at least 30 minutes every occupied hour for ventilation purposes. Fans coil fans will cycle off at night and only come on if spaces drift beyond setback temperatures, For dedicated OA fans(ventilation and exhaust air), the fans will be set to run only when the building is occupied, but will run constantly. This strategy will reduce fan energy consumption, especially during shoulder months when the heating and cooling loads are lower.

This will include taking control of the chiller, economizer loop, chilled water pumps, tower fans, condenser water pumps, changeover valves, and plant actuators. As part of this measure, the new system will support the all-variable chilled water flow ECM. Trane will accomplish this through all new Trane controls, reprogramming the entire plant for Variable Flow operations, along with Trane’s patented ‘Tower Optimization’ programming sequence. The Trane systems approach to minimization of cooling tower chiller subsystem energy use is unique. It uses a powerful algorithm to model the interaction of the cooling tower and chiller using real-time ambient conditions and chiller loading to calculate the optimal setpoint. Other systems use a broad assumption concerning the best method for determining the optimal setpoint to operate a cooling tower. The Trane strategy determines the cooling tower setpoint that minimizes the system energy usage. Trane will also program the system to utilize the existing piping and valve arrangement for free cooling /economizer during the cooler parts of the year, in support of the re-commissioning of the Water-side economizer ECM. This will be programmed as a building changeover system, controlling the existing valve actuators and tower water temperature to achieve this during colder outside temperatures. This new plant configuration will correlate into substantial energy savings, and improved tenant comfort. Existing and Proposed Values Savings for the Municipal Building were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For the condenser water reset measure, the key variables to be changed are the minimum condenser water temperature and the cooling tower equipment type. The table below shows the key values that were modified to calculate the energy savings for this measure. Table 57: Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Municipal Building Chiller Minimum Condenser Water Temperature 79°F 60°F Cooling Tower Equipment Type Cooling Tower (DOE) Optimized Tower (DOE) Savings for the Judicial Center were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For this measure, the only direct savings claimed for this measure was reducing the chiller and primary pump run times from always-on to only on when needed. This was done by removing a small false load on the plant so the plant always remained on. The table below shows the key values that were modified to calculate the energy savings for this measure.

Reprogram AHU K Factors (Judicial Center) Currently, the AHUs have many overridden values that don’t allow the programming to determine the best way to operate their heating sequences. Changing these so the programming figures out the optimum way to operate would allow the program to figure out what is best for each space. This would allow for lower minimum airflow values, which would save energy on fan power, cooling energy, and heating energy used. 260 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Existing and Proposed Values Savings were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For the reprogram AHU K factors measure, the key variable to be changed was the VAV minimum speed.

Through previous trending of the building systems, Trane personnel were able to identify VAV boxes scattered through the building that appear to be having operation problems. This includes bad controllers, air valves, and other potential issues. To ensure that the final building solution will be working to the high quality, Trane will replace these older boxes with new VAVs optimized for the new control system. Under the scope of this project, Trane will be providing Augusta-Richmond County with their Tracer® Concierge™ control system for HVAC equipment in numerous locations. Tracer Concierge uses Trane® Air-Fi™ wireless technology to communicate between devices, eliminating the need for wired components. Utilizing wireless technology makes installation of the system simpler and less time consuming, with less disruption to the facility and its occupants. As a bundled controls system of Trane components, Concierge comes with a range of built-in functions to maximize building performance including overrides, temperature setpoint changes, and daily monitoring. A single intuitive interface is used to control multiple systems, allowing for you to see and control everything from a single location. The control system is also web-enabled so that the controls can be accessed on a mobile device if desired for quicker access by maintenance personnel. Tracer Concierge is built on a platform that supports open standards and is flexible enough to work with new and existing equipment, whether or not it is from Trane. This allows for easily adding new systems and components as they are integrated into the building. Existing manual and local programmable thermostats will be replaced with new wireless thermostats. A new local interface will be installed for each building to control all of that building’s new thermostats. New thermostats will be programmed with the facility and space-specific occupancy schedules for each HVAC unit. HVAC systems will enter unoccupied mode, with setback temperatures, during typically unoccupied times, only to be energized when space temperature drifts past the unoccupied setback. The new thermostats will have override buttons to allow the system to be returned to occupied setpoint for a fixed period in the case of off-hour occupancy. Typically, this period is preset between 1 and 3 hours. The new Trane controls systems will generate energy savings by applying the following measures: 6.4.2 Air-Fi Trane Concierge Building Controls 261 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only  HVAC Scheduling and unoccupied Setback  Optimized thermostat temperature setpoints Affected Equipment Unoccupied Time Period HVAC setback will affect all equipment at all locations listed in the table below except the following.

Using occupancy sensors, the mechanical 6.4.3 Demand Control Ventilation 268 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only systems detects the level of occupancy in the room at that time and this feeds back to space controls. Dampers and fan speeds then adjust appropriately. This will not only improve occupant comfort and air quality but generate energy savings as well. Using the occupancy sensors, dampers and fan speeds are adjusted by modulating the ventilation rate to match the specific use and occupancy. Typical building ventilation systems operate at constant or pre- determined ventilation rates. This measure allows fans speeds to backdown during periods of low occupancy, reducing energy consumption by motors and fans. It also reduces the amount of outside air being brought in, reducing the overall cooling load on the building while still ensuring fresh air requirement and comfort standards are met.

Multiple spreadsheets use the methodology below to calculate savings associated with reducing the amount of outside air being brought in by a space, such as the Controls Retrofit Plus and the Kitchen DCV spreadsheet. The methodology below explains how savings were estimated for each of these scenarios. Air Handler Airflow The current total CFM (Current CFM) for each hour was calculated using the following equation. This is either constant reduced airflow in variable volume systems or the average of a cycled unit’s airflow with constant volume systems: The “Heating/Cooling coefficient” is 1 for Cooling, and the “Maximum heating CFM %” input if the system is in heating mode. The above equation was used for constant volume systems where the unit fans cycled. Otherwise the unit maintains a constant volume and its CFM is always the full load value. For VAV systems, the same equation is used, but the spreadsheet makes sure it never falls below the VAV minimum airflow. Existing Outside Air CFM 269 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only The current outside air CFM for each hour was calculated from the “Current CFM” value. For constant volume systems, the following formula was used. If the building has outside air dampers that closed at night, this value was zeroed for unoccupied times. For variable volume systems, the outside air CFM was assumed to be constant, as most VAV systems can use damper control to adjust the total airflow CFM, while maintaining constant code minimum outside air. If the building has outside air dampers that closed at night, this value was zeroed for unoccupied times as well. New Outside Air CFM with DCV Outside air CFM with DCV was calculated by multiplying the current outside air CFM by the assumed outside air reduction gained by DCV. This reduction is different if it’s in occupied or unoccupied mode. The assumption section lists the reduction percentages used for each building. It should be noted that an economizer lockout function was used to eliminate DCV operation when the systems are in cooling mode and the outside air has less enthalpy than the return air. Outside Air Conditioning Energy Savings The energy required to cool the outside air during cooling hours is calculated by the following equation, where Δh is enthalpy difference from the return air and outside air: For heating energy, the following formula was used, where Δt is temperature differential between return air and outside air: The differences between energy required to condition the outside air with and without DCV was calculated for every hour and summed up to determine to total yearly savings. Existing and Proposed Values Savings were calculated based on changing key inputs and assumptions from an existing value to a proposed value. For the demand control ventilation measure, the key variable to be changed was the schedule of outside air. The table below shows the key values that were modified to calculate the energy savings for this measure. Table 90: Existing and Proposed Values Building Name Input Name Existing Value Proposed Value Augusta Richmond County Judicial Center Outside Air Schedule Constant Varies with Occupancy 270 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Kitchen demand control ventilation uses the same concept as general demand control ventilation but focuses on kitchen equipment. The sensors are typically located in the exhaust hood above industrial kitchen equipment, such as range stove and oven, and detect cooking activity under the hood. This allows the exhaust fans to back down the amount of exhausted air during periods of low or no cooking activity. A substantial amount of air passes through the hood during normal operation, and this exhausted air must be made up via makeup air units. Thus, backing down the amount of exhausted air also allows the makeup air unit fan to back down as well. Makeup air that replaces exhausted air is often supplied by the building HVAC system. Thus, lowing the kitchen ventilation equipment in turn reduces the heating and cooling usage. Not only is occupant comfort improved through this system, but energy consumption by exhaust and makeup fan motors is decreased in addition to savings from reduced cooling and heating loads. This measure is similar to the demand control ventilation ECM above, but instead of adjusting ventilation rates based on occupancy sensors, this method uses sensors that detect cooking activity under the exhaust hood above kitchen equipment. Periods of reduced cooking activity allow the air flow of the exhaust hood to be decreased, allowing exhaust and makeup fan motors to be used less intensely and less often, resulting in energy and cost savings. This also in turn reduced the amount of air being exhausted and makeup air required, reducing HVAC heating and/or cooling usage.

For the kitchen demand control ventilation measure, the key variable to be changed was the supply and exhaust fans minimum speed during operation and allowing it to shutoff at night.

For detailed information regarding the audit, refer to the water audit appendix. Given the low water rate in Augusta and that facilities outside of the Detention Center do not pay for sewer service, water conservations measures were only financially feasible at this location. Table 93: Water and Sewer Conservation Facilities Affected Building Name Water Efficiency Retrofit Cooling Tower Credit Flush Valve Control Ozone Laundry Charles B Webster Detention Center X X X X This measure proposes to replace existing plumbing fixtures, such as toilets, urinals, sinks, and showers, with low-flow fixtures. Toilets and urinals are rated based on the amount of water per flush, while showers and sinks are rated on their flow rate during use. Over time, building codes have changed to mandate lower flow fixtures than were previously allowed. Advances in technology allow for new low-flow fixtures to provide similar performance while using a fraction of the water. The existing fixtures will be replaced, including all wear parts, with new low-flow equivalents. Replacing wear components puts the entire assembly back to its original condition and eliminates any potential for existing degradation to affect the new fixtures. While existing low flow fixtures may be excluded from this measure, including the replacement of their wear components will lead to standardized parts as well as resetting the expected lifespan of the fixtures, both of which reduce maintenance costs. Detailed information regarding the water retrofit can be found in Appendix 2. Often when water gets billed from a utility company to the customer, it is assumed that all water that is used by the customer is going to make its way to the sewer, so the total amount of water delivered is also assumed to be the same amount of water for the purposes of sewer charges. While this is true of many processes that use water, in the case of cooling towers this assumption is not true. Cooling towers use water evaporation to cool down the condenser water loop, and hence there’s no sewage produced by cooling towers. As a result, this project proposes to put a water meter on the cooling tower make-up water 6.5.1 Water Efficiency Retrofit 6.5.2 Cooling Tower Credit 272 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only line and getting a sewage credit for that water that is used by the cooling tower make-up water, hence only being charged for the water being delivered to the cooling towers and not the sewage charge. Often in detention centers, water closets can get abused and used way more by the inmates for various purposes, such as trying to eradicate evidence of contraband or just repeatedly flushing the toilet for no reason. This project proposes to install a Flush Valve Control system that helps reduce the number of times that inmates can flush the toilet in a short period of time. This allows remote access of parameters, and can set how many times inmates can flush the toilet in a certain amount of time. It is also capable of locking out flushing for a period of time if it detects abuse. This can greatly reduce the amount of water consumption used by the Detention Center. This measure proposes installing an Ozone Laundry System at the Detention Center. The oxidation of the ozone sterilizes the fabrics with a 99%+ bacterial and viral kill count, reducing risk of spreading pathogens throughout the prison. Other benefits included reduced hot water usage. This can reduce hot water usage up to 80% depending on local groundwater temperatures. Fabric drying times are also shorter, as the ozone helps release moisture in the dryer, reducing drying times by up to 20% in most cases. This furthers energy savings by reducing energy consumption by the dryers. 6.6 PV SOLAR SCOPE AND ECMS This measure proposes to install a solar photovoltaic assembly to convert solar radiation into electrical energy for use in the building. Only the Municipal Building and Diamond Lakes Library/Robert Howard Community Center are in scope for this measure. Electricity is typically provided by the utility company, who sets the tariff schedule and associated costs. Depending on the utility profile, there may be separate charges for consumption and demand. Utilizing a source of free energy such as solar radiation can offset significant utility energy costs. Additionally, it is more environmentally friendly than purchasing electricity from the utility provider, as there are no grid distribution losses and uses a 100% renewable energy source. A solar photovoltaic assembly, consisting of panels with semiconductor materials, will be installed in an area that receives large amounts of sunlight throughout the day. When sunlight contacts the panels, electrons are knocked free from the semiconductor material. Electric fields within the panels push the electrons to conducting plates which transfer the electrons to wire, creating electricity for use in the building. The image below shows how the photovoltaic cells work to produce an electrical current. 6.5.3 Flush Valve Control 6.5.4 Ozone Laundry 273 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Figure 3: Photovoltaic Cell Below is a list of buildings that are in scope for energy savings associated with building envelope improvements. For detailed information regarding the PV solar upgrade, refer to Appendix 11. Table 94: PV Solar Facilities Affected Building Name Peak kW Annual kWh Augusta Municipal Building 108 kW 209,796 kWh Diamond Lakes Library and Robert Howard Community Center 100 kW 186,642 kWh 6.7 BUILDING ENVELOPE SCOPE AND ECMS This measure primarily focuses on improving the architectural envelope of buildings. This is accomplished by adding insulation to the building envelope to reduce heat transfer and sealing cracks, gaps, and holes in the building envelope to reduce the amount of infiltration into the building. Heat is transferred through opaque surfaces by thermal conduction, where thermal energy excites the molecules causing collisions which transfer heat. Heat transfer typically occurs through different layers of composite structures with differing thermal properties, with some conducting heat much more rapidly than others. While some components of the building envelope are included for structural or other needs, building insulation is required by current energy codes to reduce the amount of heat transfer and improve thermal comfort. Older buildings may have never had portions of their envelope insulated, or the insulation may have deteriorated over time or been removed. New insulation will be added to the building envelope to improve thermal comfort and reduce energy usage by the HVAC systems. When properly insulated, the heat transfer through the building envelope is reduced and the HVAC systems do not have to work as hard 274 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only to maintain temperature setpoints. A properly insulated building will also reduce hot and cold spots, allowing for a more uniform temperature distribution throughout the space. “Weatherization” involves reducing unwanted infiltration through small openings in the building envelope that can form over time due to degrading door and window seals, building settling, general wear and tear, or from bad repairs. These gaps in the envelope allow air infiltration and exfiltration, which is uncontrolled air passing into and out of the building. Infiltration air is unconditioned, which can result in humidity problems and must eventually be conditioned by HVAC systems, which increases energy consumption. Cracks and holes in the envelope can sometimes be detected with the naked eye but are often detected using infrared thermal imaging and smoke testing. Existing cracks, gaps, and holes will be sealed to reduce building infiltration and exfiltration. By reducing the air transfer through the building envelope, less outside air will need to be conditioned, which reduces the amount of energy expended by the HVAC systems. Because excess infiltration can result in drafts and humidity problems, this measure will also improve thermal comfort and allow the HVAC systems to better maintain their comfort setpoints. Trane has identified five categories of building envelope improvements for Augusta-Richmond County. A description of each building envelope improvement is below as well as a matrix showing which improvement types are applicable to each building.  Air Leakage/Penetrations – Usually occur where building envelope elements are connected, where penetrations exist, or where cracks have developed over time. Various techniques will be used to seal these openings including insulation, drywall, polyurethane spray foam, and urethanized elastomeric sealants.  Air Leakage/Windows – Occurs where the window frames are attached to the walls. These areas will be caulked with a premium urethanized elastomeric sealant.  Conduction/Insulation – Heat transfer occurs in attic and plenum spaces where there is insufficient insulation. In these areas, polyurethane spray foam, standard batt insulation, or blown-in insulation will be applied.  Weatherstripping/Exterior Doors – Weatherstripping, door sweeps, and vertical door sweeps on exterior doors and even roll-up doors gets old, brittle, or cracked and allows air infiltration.  Compartmentalization – When not properly sealed (or compartmentalized), pipe chases and other vertical shafts can allow stack effects to exist. This creates air infiltration/exfiltration and drafty conditions within a building. These areas will be properly sealed to eliminate the stack effects. Affected Locations and Scope Below is a list of buildings that are in scope for energy savings associated with building envelope improvements. For detailed information regarding the building envelope audit, refer to the building envelope appendix.

In most instances, maintenance costs will also be reduced due to a reduction in equipment operating hours and/or loads imposed on equipment. Replacing old equipment nearing the end of its useful life will also reduce maintenance costs. New system designs often improve system diagnostics, detecting, and repairing problems before building occupants are aware they exist. Lighting system retrofits often improve space lighting level and HVAC measures often result in improved space comfort conditions and indoor air quality. Spaces are more pleasant to occupants, which often results in an increase in productivity. The operational savings benefits Trane identified during the Detailed Energy Audit for the City of Birmingham are detailed below. The lighting material deferment savings apply to the energy conservation measure involving the retrofit of various T8, T12, Incandescent Task, Exit Signs, Metal Halide high bay and other lighting fixtures located in certain buildings in Augusta-Richmond County. The room for room lighting audit in Appendix 1 details the number of fixtures to be retrofitted. Based on the detailed audit of the lighting systems and industry standard methodology the average failure rates for new lamps and ballasts are calculated. Material Savings Calculations: Lamps The first step is to calculate the Existing Average Annual Lamp Burn Outs (EAALB). This is the annual percentage of burned out lamps expected each year. It is calculated by dividing the annual hours of operation by the manufacturers stated lamp life, then multiplying by the number of lamps in each fixture. See Eq.1.

Next, for each specific lamp type, the EAALB percentage is multiplied by the Existing Estimated Lamp Replacement Labor (EELRL) which is multiplied by the Labor Cost per Hour (LCpH), giving us the Existing Estimated Lamp Replacement Labor Cost (EELRLC). The lamp replacement labor and labor cost per hour is assumed based on historical data. See Eq.10.

Next, for each specific ballast type, the EAABB percentage is multiplied by the Existing Estimated Ballast Replacement Labor (EEBRL) which is multiplied by the Labor Cost per Hour (LCpH), giving us the Existing Estimated Ballast Replacement Labor Cost (EEBRLC). The ballast replacement labor and labor cost per hour is assumed based on historical data. See Eq.13.

The difference between the Existing Total Ballast Replacement Labor Cost and the Proposed Total Ballast Replacement Labor Cost will yield the Total Ballast Labor Savings (TBLS). This procedure is performed for each specific type of ballast and fixture configuration. See Eq.15. Eq.15 𝐸𝑥𝑖𝑠𝑖𝑛𝑔 𝑇𝐵𝑅𝐿𝐶−𝑃𝑟𝑜𝑝𝑜𝑠𝑒𝑑 𝑇𝐵𝑅𝐿𝐶=𝐵𝑎𝑙𝑙𝑎𝑠𝑡 𝐿𝑎𝑏𝑜𝑟 𝑆𝑎𝑣𝑖𝑛𝑔𝑠 The savings for each of the 4 categories listed above are then added together to yield the Total Lighting Operational Savings (TLOS).

Implementation of new HVAC equipment as part of proposed Services Trane will furnish will reduce the need for the City to procure replacement HVAC equipment in many of the City’s buildings over the course of Guarantee Term.

M&V METHODOLOGY Trane is proposing a Measurement and Verification (M&V) plan that will provide Augusta Richmond County with verification of project guaranteed savings while balancing costs incurred during the M&V process. This section provides an overview of the M&V process, guidelines for the M&V approach, and details on how each ECM will be handled. Trane’s team have selected both Option A and Option C methodologies for different ECMs and locations 7.1 OVERVIEW During the Project Development phase, we strive for the ideal balance between conservative savings projections and sufficient scope to maximize your benefits from the improvements. The following process is followed during the Performance Period phase of a contract to document actual energy savings compared to the guaranteed amount. Our team will invest significant time proactively planning and scheduling data collection, analysis, and reporting activities in conjunction with your needs and availability. Collaboration Data Collection Data Analysis Reporting Resolution 284 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Collaboration: Our Performance Period process is collaborative and transparent. We’re focused on providing deliverables that communicate actual results in a manner that is easily grasped by all stakeholders. Data Collection: We will automate data collection wherever possible through leveraging the existing Trane digital controls systems and any data acquisition software from metering improvements, utility bill auditing, and renewable energy measures. This will minimize the cost of multi-year data collection and maximize value to Augusta-Richmond County. Data Analysis and As-Built Energy Savings: We will aggregate and evaluate all energy data to quantify performance and savings for each ECM. Reporting: Trane will reconcile savings and report to Augusta-Richmond County on a mutually agreed upon frequency. At the end of each guarantee year, a reconciliation report will be presented to your team for review. Resolution of Potential Issues: Trane has a long-standing history of excellence in fulfilling our promises. More than 99% of our performance contracting projects generate more savings than are guaranteed. In the event of a savings shortfall, we will stand behind our commitments and either provide Augusta-Richmond County a check for the difference or provide products or services equal to the shortfall amount (at your discretion). It is that simple. Trane adheres to the well-established International Performance Measurement and Verification Protocol (IPMVP) for confirming the benefits of the installed ECMs. The four IPMVP methods are summarized below. Together, we will select whichever Option proves to be the most prudent for each individual ECM after the project is fully developed. IPMVP Protocol Typical Uses for this Option Retrofit Isolation: Key Parameter Measurements Option A is applied to ECMs where there is one specific and key variable that best indicates the potential for energy savings. Retrofit Isolation: All Parameter Measurements Verification techniques for Option B are designed for projects where long-term continuous measurement of performance is desired. Whole Facility Verification techniques for Option C determine savings by studying overall energy use in a facility and identifying the effects of energy projects from changes in overall energy use patterns. Calibrated Simulation Option D is intended for energy retrofits where calibrated simulation of baseline energy use and calibrated simulations of post-installation energy consumption are used to measure savings from the retrofit. 7.1.1 IPMVP Protocol 285 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only The ongoing effort (e.g., predominately labor) required to monitor the performance of a project carries a cost over the life of the M&V term. Hence, it is an expense and typically must be shown separate from asset expenditures. At a minimum, each M&V Option should be considered within the context of the:  Absolute magnitude of the savings  Relative magnitude of savings compared to the total energy consumption of the facility  Complexity of the ECM(s) implemented Trane’s team have selected both Option A and Option C methodologies for different ECMs and locations Option A Costs This option is typically applied to lighting, water and building envelope retrofits. In the case of lighting, for example, the reduction in power consumption by replacing an inefficient lamp with a more efficient lamp is well understood. Therefore, if the hours of operation can be agreed upon (and therefore stipulated), then the amount of savings is easily determined. If the size of the building/retrofit was small, then it would not make sense to erode savings by paying for an ongoing reconciliation of the energy consumption via a more expensive M&V option. Even in a large building/retrofit, if the magnitude of lighting savings was small compared to the total energy consumption, then the natural fluctuation of the building’s energy consumption may obscure the lighting reduction. Option C Costs Typically applied when multiple ECMs are implemented within a facility and there is no need to measure and verify the performance of each ECM independently. Also, the aggregate of the savings should be significant enough that normal building energy fluctuations will not obscure the ability to see the savings at the whole building utility meter(s). This method compares the monthly utility bills with calibrated computer models, and is routinely adjusted for weather conditions, production conditions, etc. that may materially affect the tuning of the computer models. 7.2 M&V ECM TABLE The following table details the proposed M&V methodology, by IPMVP Option category, for each proposed ECM.

Currently, a wide variety of fluorescent, incandescent, metal halide, and other types of lighting technologies exist throughout Augusta-Richmond County facilities. As stated in the scope exhibit Trane will retrofit/upgrade certain fixtures with LED technology. Measured power draw (watts) for a statistically valid sample of the lamp/ballast combinations have already been measured by Trane and its partners. This added up to 180 individual measurements across numerous facilities. This represents the data set for the projects’ pre-retrofit measurement. These same locations will also receive Post-Retrofit testing in order to verify the avoided energy consumption (savings). The average burn hours for these lamps are determined from the occupancy schedules and light sensing data logging during the survey phase. These burn hours will be agreed upon by Trane and Augusta Richmond County as fact and would not be otherwise measured or confirmed. For this project, energy consumption reduction will be the only measured cost reduction. the measured kW difference is multiplied by the agreed upon burn hours to obtain kWh savings. The kWh multiplied by the rate schedule kWh charges will be the avoided costs. This ECM will only be validated one time, occurring during the installation period; and those same results will be reported as fact in all future reports without any future measurements. Currently, the Charles B Webster Detention Center has a variety of water fixtures. Many of them are of the older high flow variety. Trane will retrofit/upgrade the older, high flow fixtures with modern low flow fixtures. A statistically valid sample of the toilets, urinals, shower, faucets, etc. would receive Pre & Post-Retrofit testing in order to determine the avoided water consumption per usage. The average number of uses per year for a given fixture type in a given type of occupancy is published in many engineering manuals such as ASHRAE and by associations such as AWWA. The avoided (saved) water usage would be multiplied by the published rate schedule to determine the annual savings. 7.3.1 Lighting 7.3.2 Water Fixtures 288 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only For the flush valve controls, the avoided water usage comes from a reduction in occupant use of the fixture. To avoid interaction with occupants or equipment having to be installed in occupant areas, this reduction in use will be stipulated and agreed upon by both Trane and Augusta Richmond County. Trane will inspect and verify proper operation of the flush valve controls after installation. Two measures included in this scope will be fully stipulated. These are the ozone laundry system and upgrades to the ice machines. These two measures make up less than 23% of the total savings, most of which is energy savings instead of water savings. It will be stipulated and reported as fact on an annual basis and will not otherwise be measured or confirmed for the life of the contract. As with lighting, this ECM will only be validated one time, occurring during the installation period; and those same results will be reported as fact in all future reports without any future measurements. Currently, many of the Augusta Richmond County buildings have holes/cracks in the walls, soffit/fascia failures, insulation deficiencies, window frame deficiencies, etc. These issues impose excessive HVAC loads on the buildings as well as create comfort issues for the occupants. Trane will seal the openings and add insulation (as outlined in the scope exhibit) to reduce the factors leading to the inefficiency. The ECMs basically consists of sealing cracks and holes by various means and adding insulation where needed. The savings are developed using common engineering equations & techniques with the appropriate factors applied. On the 50 buildings where this ECM is proposed, the savings represents around 13% of the total project savings. For the Pre-Retrofit measurement Trane measured the size of each opening and the existing amounts of insulation. The Post-Retrofit measurement is to measure the size of the opening after it has been repaired. Since in this project the openings are to be completely sealed, then effectively, all this means is that a visual inspection can be made confirming that the work was completed. Similarly, for the insulation a visual inspection can be made that the work was completed. This ECM will only be validated one time, occurring during the installation period; and those same results will be reported as fact in all future reports without any future measurements. Currently, domestic city water is used as makeup water for the cooling towers at the Charles B Webster Detention Center and sewage charges are applied even though most of this water never enters the sewage system. New water meters will be installed on the cooling towers to record the water consumption. This data will be reported to or read by the water utility which will issue a credit back to the Detention Center. The sewer cost savings for submetering cooling tower makeup water and blowdown were calculated using the industry standard engineering equations and techniques. Trane will verify the proper installation and operation of the proposed Cooling Tower Submeters and that the submeters are communicating with the Customer’s BAS to facilitate Customer submission of sewer credit request documentation to the sewer authority. Due to the dynamic operation of cooling towers and their dependence on the weather, this estimated avoided consumption is agreed upon by Trane and the Augusta Richmond County. It will be stipulated and reported as fact on an annual basis and will not otherwise be measured or confirmed for the life of the contract. Currently, Augusta Richmond County has a large number of pieces of HVAC equipment that is at or near the end of its useful life. As outlined in the scope exhibit, Trane will replace certain DX equipment and chillers, as well as adding VFDs to pumps and cooling tower fans. For the DX equipment, Trane will select a representative sample of the equipment and perform Pre-Retrofit testing on the selected existing 7.3.3 Building Envelope ECM 7.3.4 Cooling Tower Water Submetering 7.3.5 HVAC Equipment ECMs 289 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only equipment. Trane will use manufacturer data to determine Post-Retrofit performance on the related new equipment to determine the avoided energy consumption. The Pre & Post measurements will be applied across all DX equipment to calculate the total avoided energy consumption. For the chillers, and VFDs, there are only a few locations that use Option A, so all equipment will be measured. Chillers (Webster Detention Center) The location for this measure is the Charles B Webster Detention Center old chiller plant. Trane utilized TRACETM 700 energy models to simulate energy consumption of the Detention Center and calibrated the model against historical energy consumption data. Trane will measure chilled water supply temperature, chilled water return temperature, chilled water flow rate, and chiller input power (kW) at multiple chiller load points and ambient temperature conditions in order to compute chiller operating efficiency, kW/Ton, for each chiller for the Pre-Retrofit and Post-Retrofit cases. The Pre & Post measurements will be used as inputs to the applicable TRACETM 700 energy model. The model will be recalibrated and then rerun to calculate avoided energy consumption. This ECM will only be validated one time, occurring during the installation period; and those same results will be reported as fact in all future reports without any future measurements. HVAC: DX Rooftop Units and Split Systems Trane utilized a spreadsheet energy model to simulate building energy consumption of the existing AC systems. Known parameters such as local weather data, occupancy data, utility costs, percent outside air, etc., were all utilized in modeling of the systems. The accuracy of the pre-retrofit energy use is partially validated by its correlation to the actual utility data for the buildings under consideration. Trane will also measure energy consumption and cooling output for a representative sample of the units being replaced. This will include units from a variety of locations. For these locations one-time measurements of the unit efficiency will be performed, by measuring unit power draw, air temperatures, and unit air flow. Trane will use manufacturer’s energy performance data for the new AC systems that will be installed during the Installation period to compute energy performance for these new AC systems. During the Installation Period, Trane will use equipment cutsheet data to confirm that the correct units have been procured and properly installed to ensure that the new AC system energy performance meets or exceeds what was used to compute AC system energy performance as part of the Investment Grade Audit. Confirmation of new AC system energy performance rating data will be conducted one time only, during the Installation Period Trane will apply the Pre-Retrofit and Post-Retrofit AC system energy performance data as input to the applicable spreadsheet energy models. This measured AC system energy performance data was used as input to the spreadsheet energy model or software energy model, as applicable, which was used to calculate AC system energy performance and resultant energy savings. All-Variable Chilled Water Pumping (Webster Detention Center) Savings for this measure were calculated in Trane Trace 700. The majority of the savings will be achieved by a reduction in pumping energy. The energy consumption of the current pumps can be defined as the power draw of the pump times the number of annual operating hours total for all pumps. For the Pre-retrofit performance, an amp and voltmeter will be used to measure the power draw of the existing pumps. Hours of operation will be an agreed upon parameter, based on the run-time calculated in the Trane Trace 700 energy model. For the Post retrofit performance, Trane will trend operation of the chilled water system over a range of operating points during normal operation. Trane will compare the chiller load and pump speed to determine a relative average pump power draw of typical operation ranges. The measured power draw based on the VFD readings will be multiplied by the agreed upon run hours to get Post retrofit energy consumption. 290 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Cooling Tower Retrofit & New VFD (Webster Detention Center) This measure will include replacement of the old plant cooling tower and the addition of VFD for the new tower fan. Operation of this equipment will be directed by the newly installed chiller plant optimization sequencing. Trane will fully commission the new tower and controls system and ensure the equipment is operating properly. Avoided energy consumption for this measure was calculated in a Trane Trace 700 energy model. It will be stipulated and reported as fact on an annual basis and will not otherwise be measured or confirmed for the life of the contract. For the buildings where currently the HVAC equipment runs 24/7 without any unoccupied (generally nights & weekends) temperature setbacks, schedules will be implemented to allow the equipment to run at reduced levels during unoccupied time periods. Trane utilized either spreadsheet calculations or Trane TRACETM 700 building energy models to simulate the energy consumption of the buildings. Known parameters such as local weather data, occupancy data, utility costs, percent outside air, etc., were all utilized in modeling the systems. The accuracy of the pre-retrofit energy use was validated by its correlation to the actual utility data for the buildings under consideration. Trane proposes to confirm on a periodic basis that the schedules are still in effect. If the schedule is active then the savings will be deemed to have been obtained. Although, this is in the Option A M&V category, the confirmations would be throughout the life of the project as opposed to just a one-time M&V as on the other ECMs. Performing this confirmation periodically helps to ensure that the savings will persist over the life of the project. The applicable spreadsheet calculations and TRACETM 700 model consumption savings are multiplied by the project agreed utility rates for each location. Therefore, the spreadsheet or model can calculate the appropriate energy units saved as well as dollars saved. If the schedule is in effect, then the applicable spreadsheet/model will serve to determine the savings. If the schedules are modified, then the appropriate edits will be made to the applicable spreadsheet or model for recalculation. The updated calculations will be used to make baseline adjustments to the savings calculations. This applies to the Diamond Lakes Library and Robert Howard Community Center. The savings here have been calculated using the PV Watts, based on typical local weather and solar data, and design peak output of the PV system. The weather and solar data for the site will be stipulated and not measured. After the installation of this system, Trane will use installed metering equipment to monitor and measure the peak kW output of the system. The measured peak output will be re-input into the PV watts program to calculate the annual savings. This measurement will be taken on once. 7.4 IPMVP OPTION C ECMs The energy savings at the Municipal Building and the Judicial Center will be measured and verified according to IPMVP Option C guidelines. This option determines savings by measuring the energy use of the whole building by collecting, monitoring, and comparing utility bills for the Baseline Year (2018-2019) and the Performance Period. All energy (electricity and gas) savings for these locations will fall under Option C. Calculations will follow the below framework: Avoided Energy Consumption/Cost (i.e. – Savings) = Energy That Would Have Been Consumed (had the ECMs not been installed) – Actual Energy Consumption (from the current bills) for the reporting period. Utility bill cycles spanning the middle of a month to the middle of the next month must be adjusted to match the guarantee term which begins with the first day of a month. 7.3.6 HVAC Controls Set Back ECMs 7.3.7 Solar PV ECM 291 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only Trane proposes performing the IPMVP “Option C – Whole Facility” method on two buildings: Augusta Municipal Building Augusta Richmond County Judicial Center These buildings constitute about 22.5% of the total program square footage and about 28% of the total energy savings. Option C M&V consists of gathering several pieces of data each month. This data consists of the Electrical and Natural Gas utility bills, local weather data, and any changes in building usage. The data is then keypunched into an energy accounting/analysis software called Metrix and the adjusted baseline energy consumption is calculated. This value is then compared to the actual energy consumption for the same time period to determine the level of avoided consumption. The respective savings/deficit amounts are multiplied by the proper utility rate schedule to determine the value of the dollar savings. 292 © 2020 Trane - All rights reserved Detailed Energy Audit Report – Augusta-Richmond County Savings Figures are Projections Only 8. TRANE SERVICE Trane plans to provide two types of on-going service once the proposed energy performance contract is implemented and commissioned.

(REF 18-164) Background:Many of Augusta, Georgia facilities and buildings are not energy efficient, in accordance with today’s standards and would benefit from upgrades with more energy efficient equipment and methods available on the market today. A facility assessment, of this nature, has never been completed and information derived from this assessment would prove valuable while planning for our capital improvements of the present and future. On May 7, 2019 Trane, Inc. was approved to complete a Phase I Investment Grade facility audit on 89 Augusta, Georgia owned facilities. Phase II requires Augusta to enter into a Performance Contract, project source funding details will be returned once bids have been evaluated. Analysis:Trane, Inc. has worked intimately in Augusta’s facilities to assess our energy efficiency and equipment performance in comparison to industry standards. The recommendations provided, if implemented, will allow Augusta to capitalize on savings generated from lowered energy consumption to finance the upgrades recommended through a performance contract, while reaping the benefits of savings. 1. Proposals for the performance contract financing ($24.5M) will be obtained and returned for Commission approval. Customer Capital ($4.5M) funded through SPLOST 8. 2.

POLICY: Timely and appropriate acquisition and maintenance of fleet resources is essential in this Governments mission to provide services to the Citizens of Augusta. This Governments fleet is nothing more than a tool for the provision of services to the general public by government employees. To facilitate budgeting and planning of resources this regulation establishes "Life Expectancies" for fleet equipment. The Life Expectancies are used as planning parameters and identify potential candidates for replacement. Actual replacement criteria is established using a point system which considers; age, mileslhours, reliability, maintenance and repair costs and overall condition. The criteria will identify specific units requiring replacement. Vehicles and equipment purchased with government funds represent a valuable resource and as such will be preserved and maintained to legal and established standards published in this policy. The replacement criteria published in this regulation are not absolute and are contingent on available funds and overall condition of equipment within the "window" of replacement. 2. PURPOSE: The timely replacement of fleet vehicles and equipment is necessary to encourage and maintain a safe, efficient, reliable and cost effective fleet. This policy establishes acceptable replacement criteria for replacement consideration of existing fleet assets. In addition, it establishes minimum safety and mechanical standards of equipment that are not replaced due to budgetary constraints. The overall goal of this policy is to reduce overall equipment life cycle costs (procurement, maintenance, and disposal). It is the intent of this policy to replace vehicles and equipment when owning and operating them cost more than owning and operating their replacements. 3. ECONOMIC CONCEPT: All vehicles and equipment within the fleet will eventually wear out. As they age they become increasingly more expensive to operate and maintain and less reliable and safe to use. In order to minimize total vehicle or equipment cost, replacement should be made when the operating cost (maintenance, repair and fuel) exceeds the value of the vehicle over time. 4.

DEFINITIONS: 5.1 Life Cycle Cost- those costs associated with ownership, operating expenses throughout the working life of equipment. 5.2 Life Expectancy: The expected number of years a vehicle or piece of equipment is expected to provide economical, cost effective service in the performance of its primary intended use. 6. GENERAL: 6.1 In establishing the Fleet Replacement Policy, tbe Augusta Commission will establish a life expectancy for each vehicle and piece of fleet equipment, (Appendix I). The life expectancy will be expressed in age, miles, or hours of operation. 6.2 The life expectancy of any new type equipment or vehicle, not currently in the inventory, will be established and presented as part of the agenda item presented to the Commission for the approval to purchase the item. 6.3 The life expectancy allows for the timely planning of replacements of fleet assets for the purpose of annual budget submission. It has a direct affect on the annual Capital Outlay program as well as the "Non-Contract" maintenance budget. 6.4 The life expectancy is a primary factor, but not sole factor, in consideration of potential replacements and is used for budget planning. 6.5 Replacement criteria is an evaluative process whereby potential replacements, identified from the Life Expectancy evaluation, are graded individually to determine the necessity of replacement and assist in prioritizing replacements. Each vehicle will be evaluated according to the matrix at Appendix II. 6.6 Vehicle replacement is contingent on available funding. 7. PROCESS of REPLACEMENT: 7.1 Fleet Management will maintain an inventory of all fleet assets, the department/division assigned to, the date acquired and the replacement date. This infomlation will be provided to each department at the beginning of each annual budget process. 7.2 Department Heads will review their inventories to detelmine those items that require replacement and establish a priority of need for their depmiment. The information will be displayed on the Budget Form C, Capital Equipment/Budget Request (Appendix IV). 7.3 A copy of this form will be forwarded to the Fleet Manager with the original being submitted with the requested budget to Finance. 7.4 Fleet Management will consolidate all capital outlay requests, by major fund, and formulate a recommendation of replacement, through the Finance Director to the Administrator. 8. Replacement Criteria: (See Appendix II) 8.1 Consideration for replacement will be based on several factors: life expectancy, actual age, operating cost (maintenance and fue!), annual mileage/utilization, reliability, and resale value. Each vehicle or piece of equipment (capital expenditure) will be evaluated by Fleet Management using the form at Appendix II to determine if replacement is required. 8.2 Should the vehicle meet the replacement requirements and funding is available, the information will from the evaluation will be transposed to the Replacement Criteria Foml, Appendix IV) and submitted with the Agenda for purchase approval. 8.2 Vehicles which have been classified as totaled will have priority in the replacement process in the next fiscal year. 9. Vehicles Retained Beyond Life Expectancy. 9.1 A number of Public Safety, pursuit vehicles are replaced in order to ensure reliability. 9.2 Public Safety vehicles taken out of public safety service will be assessed by Fleet Management to determine the possibility of continued use in an administrative capacity. 9.3 Vehicles retained beyond their life expectancy will be maintained to a level which meets the legal requirements of safety established by Georgia Law (O.c.G.A. Chapter 8, Section 40) Appendix V. 10. ANNUAL FLEET REVIEW: At the end of each calendar year, Fleet Management will calculate the annual mileage for each vehicle within the fleet. Vehicles which have been driven 5,000 miles or less in the year will be identified and a list published to the Finance Director and Administrator. Each Department Director will be provided a list of vehicles within their department with 5,000 miles or less (miles driven in a year). Directors must justify the retention of these vehicles in their active fleet. Fleet Management will consolidate the individual justifications and provide a recommendation through the Director of Finance to the Administrator for approval to retain or recommendation to turn the vehicle in. 11. FUNDING: 11.1 General Fund: Departments funded by the General Fund will submit capital asset requirements each year as part of the budget process. Fleet Management will consolidate all capital outlay requests and provide a General Fund Capital Outlay replacement plan for that calendar year. The recommendation will be forwarded through the Director of Finance to the Administrator. 11.2 Enterprise Funds - Each Department funded as an Enterprise Fund will submit capital asset requirements as part ofthe budget process. Fleet Management will review all requirements to ensure they are consistent with this policy. 11.3 Grant Funds - Departments which have access to grants are responsible for the application and administration required to obtain the grant. Fleet Management will provide any necessary vehicle/equipment specifications and appropriate purchasing processing including proposals in accordance with purchasing requirements). 11.4 Seizure Funds - (applicable to Sheriff and District Attorney) - These funds are awarded based on a court order and are under the control of the respective elected official. They may be used by the receiving agency, have no affect on the General Fund and may be used for vehicle and/or equipment purchases and/or used in compliance with the Court Order. Fleet Management will assist with the processing of necessary administration associated with the purchase of vehicles or equipment. 11.5 Special One Cent Sales Tax (SPLOST) - The purchase of vehicles or equipment using SPLOST funds will be closely monitored to ensure that any expenditures are consistent with the approved referendum. 12. PROPONENT: The proponent agency for this policy is: Finance Department, Attention: Fleet Management Division. Any suggestions for improvement or comments should be addressed to Finance Department, Attention: Fleet Management Division. 13. This policy supercedes the Augusta-Richmond County Vehicle and Equipment Replacement Criteria, dated 1 September 1998.

Siddall, Fleet Manager DATE:August 17,1998 SUBJECT: criteria. Motion to approve the Augusta-Richmond County vehicle and equipment replacement CAPTION: criteria. Motion to approve the Augusta-Richmond County vehicle and equipment replacement BACKGROUND: In performance of the duties of the Fleet Management Department, the section requires the need to determine when equipment should be replaced. To effectively determine this, a replacement limitation criteria has to be established as a point ofreference for the determination. The current Fleet Maintenance Contract, Section 5.2 - Limitations, contains language stipulating that the replacement guidelines will be established and that all repair cost for equipment that has exceeded it's life will be charged non-contract cost. ANALYSIS: Common fleet practices require a vehicle replacement criteria be established, in order to determine if maintenance funds should be spent to repair a unit, or ifthe unit should be salvaged. FINANCIAL IMPACT: Funding currently established for contracted services would be reduced as equipment becomes overage p.nd the funds would then be transferred to non-contract funds. Approved repairs, as authorized by the Fleet Manager, would be funded with the non-contract revenues. ALTERNATIVES: I. Approve the replacement criteria for Augusta-Richmond. 2. Do not approve the request and hamper the effectiveness ofall of the City/County Departments. RECOMMENDATION: Approve the replacement criteria.
