1.0 EXECUTIVE SUMMARY An investment grade energy audit (IGEA) was conducted for 3 public housing properties operated by Saratoga Springs Housing Authority. This report provides a description of the existing site conditions, the baseline energy consumption, a utility benchmarking analysis, and Facility Improvement Measures (FIMs) that will be implemented through this energy performance contract (EPC). A summary of proposed FIMs by site is shown in Table 1. Table 1. List of Measures by Site Common Area & Apt Lighting Boiler Upgrades Heating System Re Piping & Control DHW Pipe Insulation Buildingenvelope Low Flow Aerators Low Flow Shower Heads Stonequist X X X X X X X Jefferson X X X X Vanderbilt X X X X X X Low Flow Water Closets A summary of the energy savings, cost savings, and simple payback period for each ECM by site based on current utility rates is shown in Table 2. The proposed FIMs are expected to result in an annual energy savings of 464,924 kwh of electricity, 80,084 therms of natural gas, and 584,867 CF of water. At current utility rates, the total annual cost savings associated with the FIMs are $141,659. With guaranteed savings at 93% of total savings, the guaranteed saving are $131,743 per year. The construction costs for this project are estimated at $1,515,019 with an additional $592,787 for project soft costs and ESCO profit for a total project cost of $2,107,806. A cash flow for the project is provided in Table 3. The cash flow is based on a repayment term of 20 years, a construction period of 15 months, and a 3.1% interest rate. Cost savings are based on the current utility rates and are escalated annually based on historical utility rates data from the BLS, EIA, and the local water and sewer provider. Annual escalation rates for electric, natural gas, and water are 2%, 0.5%, and 3% respectively. The cash flow also considers annual M&V fees as well as replacement reserve costs for savings generating equipment such as lighting, showerheads, aerators, and refrigerators that will require replacements during the EPC incentive term. Overall, the cash flow is net positive for each year of the EPC term and the percentage of guaranteed savings to project costs over the repayment period is 98.7%.

3.0 UTILITY BASELINES, ALLOWANCES, AND BENCHMARKING 3.1 Baseline Utility Consumption & Adjustments 3.1.1 Baseline Utility Consumption The utility consumption baselines are based on the 3 year rolling baseline in place at the time of submission of the EPC for HUD approval with appropriate adjustments. The utility baselines are established for all utilities that are paid by the Authority, and a summary by site is provided in Table 8, Table 9, and Table 10. The detailed data to support these values is provided in Attachment A. Table 8.

3.1.2 Baseline adjustments Baseline adjustments are necessary for water, electricity, and natural gas for AMP 2 Stonequist Apartments. The adjustment for water is necessary because the existing water meter has been providing faulty (low) readings for the duration of the baseline period and the meter will be replaced with a new, properly calibrated water meter as part of this project. The water consumption registered by the new water meter will be higher than the baseline consumption. The magnitude of the adjustment will be based on a comparison of meter readings from the existing water meter and an ultrasonic flow meter placed in series with it. The difference between the meter readings shall establish a correction factor multiplier that will be applied to the baseline data to establish the adjusted consumption over the baseline period. Based on the data collected at the time of this report the meter correction factor is 6.8, meaning that the ultrasonic flow meter measured usage 6.8 times greater than what was registered by the utility water meter. The multiplier leads to an adjustment of 965,385 CF to be added to the 3 year average consumption. The raw data and the calculations to determine the adjusted baseline consumption are provided in Attachment B. A second adjustment is needed to account for increased electric and natural gas consumption at Stonequist due to 12 rooftop exhaust fans being brought back online. The building has a total of 14 rooftop exhaust fans and 12 of them have been offline for the duration of the baseline period. Bringing the fans back online will result in increased electric consumption to drive the fan motors, and increased natural gas consumption to heat a larger volume of makeup air during the heating season. The cfm flow rates and motor horsepower ratings for the new exhaust fans to be installed are the basis for the baseline adjustment. The calculations and assumptions used to determine the baseline adjustments are provided in Attachment B. A summary of the baseline adjustments to be applied to each utility are provided below in Table 11. Table 11.

The sites for which utility allowance are provided include Jefferson Terrace and Vanderbilt Terrace. At Jefferson Terrace both natural gas and electric service are resident paid. At Vanderbilt Terrace only electric service is resident paid. All other utility services at these properties are Authority paid. All utilities at Stonequist Apartments are Authority paid and there are no utility allowances for that site. The existing allowances in place are as follows in Table 17. Table 17.

3.3 Benchmarking Analysis Benchmarking provides information to improve decisions regarding where to focus investment by comparing annual electric, natural gas, and water consumption baseline data among the sites. The baseline period for benchmarking is July 2010 through June 2013. 3.3.1 Energy and Water Usage Intensities Electric, natural gas, and total energy usage were compared across the sites by converting to common energy units (kbtu) and normalizing on a per square foot basis. The usage intensities (kbtu/sf) include both metered consumption from Authority Paid utilities as well as stipulated resident paid allowance consumption values. The usage intensities are broken out for the preretrofit condition, the adjusted pre retrofit condition (which accounts for the baseline adjustments as described in Section 3.1.2), and the projected post retrofit condition (adjusted pre retrofit minus the projected savings shown in Table 2). Figure 1 shows the analysis for the electric usage. The highest electric usage intensity is at Jefferson, however it should be noted that the water heaters at that site operate on electricity while other sites have natural gas fired water heaters. Figure 1. Annual Electric Energy Usage Intensity Figure 2 shows the normalized comparison of the gas usage. Vanderbilt has the highest gas per square foot. Saratoga Springs Housing Authority IGEA Report - Page 16 of 84

Figure 2. Annual Natural Gas Energy Usage Intensity Figure 3 shows the combined total energy usage intensity for electric and natural gas. Figure 3. Total Annual Energy Usage Intensity Water usage intensity was compared across sites by converting to gallons and normalizing on a per person per day basis (GPPD). Figure 4 shows a normalized comparison of the water usage. The baseline adjustment multiplier of 6.8 (as discussed in Section 3.1.2) is included in this benchmarking analysis to account for the known metering issue at Stonequist Apartments. Saratoga Springs Housing Authority IGEA Report - Page 17 of 84

Figure 4. Total Annual Water Usage Intensity The energy used for domestic hot water at Stonequist is estimated based on disaggregated utility bill data and short term measurements of hot water usage. Energy consumption estimates for domestic hot water at Jefferson and Vanderbilt Terrace are based on assumed annual hot water usage and end use temperatures. Because domestic hot water is provided by gas at Stonequist and Vanderbilt, but by electric at Jefferson, the energy usage for water heating was converted to common energy units before being normalized on a per person basis. Figure 5 shows a normalized comparison of the domestic hot water energy usage at each site. Figure 5.

3.3.2 Utility Metering Existing utility metering at Stonequist Apartments, Jefferson, and Vanderbilt Terrace was assessed. Stonequist has master meters for electric, gas, and water. Apartments and common areas at Jefferson Terrace are individually retail metered for gas and electric. Gas and electric service is resident paid for apartments and Authority paid for common areas. Water service at Jefferson Terrace is master metered. Electric service at Vanderbilt is individually retail metered for apartments and common areas. Apartment accounts are resident paid while common area accounts are Authority paid. Natural gas and water service at Vanderbilt are both master metered. A matrix showing the metering configurations of each utility by site is provided in Table 18. Table 18.

Measures where savings will be captured through a utility allowance reduction use the current marginal utility rates while measures captured through frozen base or add on subsidy use the current average rate. A summary of the utility rates used for analysis are provided in Table 19 below. A detailed buildup of the current marginal rates and the current average rates are provided in Attachment C. Table 19.

4.0 ENERGY AND WATER CONSERVATION The following is a discussion of each FIM that will be implemented at SSHA s properties. These measures are outlined in more detail with savings, cost, and payback estimates summarized in Attachment D. 4.1 Lighting Retrofits FIM #1, 3, 5, 10, 11, & 12 Apartment and Common Area Lighting The retrofits for lighting upgrades at each site will include apartments, common areas, and the exterior. The existing interior lighting at all sites consists of a combination of linear fluorescent, incandescent, and CFL lamps. Existing linear fluorescent fixtures will be retrofitted with new LED lamps. In most cases, the retrofit kits will utilize the existing fixtures and replace the existing fluorescent components with lower wattage linear LED lamps. Existing screw in CFL and incandescent lamps can be replaced with new high efficiency screw in LED lamps. This project will also include installing occupancy based lighting controls to turn lights on and off automatically in common areas. Smaller spaces such as offices and restroom will receive dual technology (passive IR and ultrasonic) switch mounted sensors. Larger spaces will receive ceiling mounted dual technology sensors. The sensors will effectively reduce energy consumption by turning off the light when human presence is not detected in the space, thereby reducing the operating hours and extending the life of the lamps while also reducing energy consumption. A detailed lighting survey showing existing and proposed fixtures and locations for lighting controls for each area is provided in the lighting analysis in Attachment D. 4.2 Mechanical System Upgrades Boiler upgrades are proposed at two sites where natural gas usage is master metered. The retrofits are intended to replace aging infrastructure that is near the end of its useful life. SSHA can achieve operational savings by upgrading these units with more efficient condensing models. Although not included in the savings analysis, additional savings may be possible from reduced maintenance needs of the new units. Saratoga Springs Housing Authority IGEA Report - Page 20 of 84

FIM #7 Stonequist Apartments Boiler & DHW Upgrades Existing System Description The Stonequist high rise contains a space heating and domestic hot water plant on the 8 th floor. The space occupies the center location on the west side of the building and extends two stories, 8 th and 9 th floor. Combustion air for the boilers is brought in through louvers on the west wall and flue gasses are routed directly up through the roof. Primary fuel is natural gas. The plant and equipment is mostly original, dating back to 1971. At the heart of the plant are four (4) Peerless atmospheric hot water boilers fired with natural gas. The boilers are model number 210 11 W S and are identical, each with an input rating of 2,100,000 BTU per hour and an output rating of 1,680,000 BTU per hour. Each boiler has ten (10) cast iron sections and capable of turndown to 840,000 BTU per hour, or half fire. The boilers provide both heating hot water (HHW) and heat for DHW through a common header. Heating hot water is drawn off the header by a set of three main circulation pumps operated as East, West and standby. Only two pumps are in operation when the boiler plant is enabled with the third pump in stand by, ready to back up either of the others. Therefore the building is served by two separate HHW supplies identified as East and West. Each supply loop contains a three way mixing valve that should operate according to a hot water reset schedule, mixing return water with boiler supply water to attain a supply water set point as a function of outdoor air temperature. The mixing valves and hot water reset system are under pneumatic control and original. Pneumatic Mixing Valve Existing Heating Hot Water Reset Controls Saratoga Springs Housing Authority IGEA Report - Page 21 of 84

The domestic hot water is generated by pumping boiler water through tube bundles of two DHW storage tanks. A temperature sensor on each tank controls a pump that circulated heating hot water from the boiler plant header through a tube bundle in the tank. When tank temperature reaches set point, the pump shuts off. At least one of the main boilers must remain enabled throughout the summer to provide heating hot water to the header and subsequently the DHW tanks as required. DHW Tank Temperature Sensor Switch Existing DHW Tank Existing Conditions The heating plant is showing its age. The boilers are at their end of useful life. Pipe insulation has degraded in many spots and is missing from sections of heating and DHW piping. Circulation pumps and pump motors have received maintenance and high efficiency motors have been installed. The pumps and motors appear to be in good working order. Manual gate valves and check valves are un insulated, mainly because they require periodic maintenance and removing permanent insulation is inconvenient. Excessive heat is lost from these valves due to the lack of insulation, particularly with the inoperative condition of the hot water reset functions. Controls are original pneumatic and function was observed to be limited. On a day when outdoor air temperature was 36 F, the HHW circulation temperature to the building was 170 F indicating lack of hot water reset function. Saratoga Springs Housing Authority IGEA Report - Page 22 of 84

The boilers do not have primary circulation pumps but rely on the building circulation pumps to maintain flow. If the building pumps are not in operation, there is no forced flow through the boiler line up and whatever flow does exist is the result of thermosiphoning. Domestic water heating in the summer relies on thermosiphoning to heat the boiler supply header since the main building circulation pumps are off during the non space heating season. Proposed Solution Provide a heating hot water plant with full range outdoor air reset capability using high efficiency equipment. Design heating conditions shall be met using two (2) non condensing natural gas fired boilers capable of HHW reset from 140 ⁰F to 220 ⁰F and one (1) condensing boiler capable of HHW reset from 110 ⁰F to 190 ⁰F. A new digital control system shall monitor outdoor air temperature and provide a HHW set point to the boiler control panel based on a pre set hot water reset schedule residing within the building controller. The boiler control panel shall supervise which boiler(s) operate to meet supply water temperature requirements. The new building controller shall also enable boiler plant and associated building circulation pumps automatically based on outdoor air temperature. In conjunction with the proposed solution described for FIM #9, the building secondary pumps will be variable speed and driven by variable frequency drives (VFDs) Building DHW shall be separated from the space heating plant and shall be a tankless system using high efficiency natural gas condensing equipment. There shall be two (2) dedicated DHW boilers for redundancy. DHW storage tanks will no longer be needed and will be bypassed. A description of the savings analysis is provided in Attachment E. FIM #8 Vanderbilt Terrace Boiler Upgrades Existing System Description Each of the Vanderbilt Terrace buildings has one standard efficiency gas fired hot water boiler which provides heating to all of the residences in that building via baseboard fin tube radiators with non limiting radiator control valves. These boilers have all been replaced recently, with the exception of one (Building #15) which is nearing the end of its useful life. Saratoga Springs Housing Authority IGEA Report - Page 23 of 84

Proposed Solution The existing boiler at Building #15 will be replaced with a new condensing hot water boiler. The new condensing boiler will be significantly more efficient than the existing boiler, particularly during low load conditions and when operating at lower temperatures. The new boiler will use OA reset controls. A description of the savings analysis is provided in Attachment D. FIM #9 Stonequist Heating System Controls Existing System Description The original design is a constant volume, free flow system originally implemented with pneumatic HHW reset at the boiler room. There are two HHW circulation loops with each loop designed for a flow rate of 200 gallons per minute. One loop serves the east side of the building and the other serves the west. Under design heating conditions and a temperature drop of 20 degrees Fahrenheit across the supply and return for both loops, the building heating load is calculated to be 4,000,000 BTU per hour or roughly the capacity of two of the four boilers. To compensate for the free flow of HHW, hot water reset was implemented separately for each side of the building through the use of three way valves which mix return water with supply water to obtain programmed supply water temperature. There are no other temperature controls in the apartments, which basically contain fin tube and shut off valves. Pictures of a three way valve and the HHW reset controls are shown under the FIM 7 write up. Existing Conditions The lack of adequate HHW reset and the original free flow design leads to constant overheating in the apartment units. Temperature logging has indicated that the spaces are maintained at approximately 80 ⁰F with no way to control the temperature in individual apartments other than opening windows, installing fans, or running mechanical cooling during the winter. The constant volume (constant motor speed) HHW pumping is in use throughout the heating season, because it is controlled solely by outdoor air temperature, irrespective of space temperature. Proposed Solution Saratoga Springs Housing Authority IGEA Report - Page 24 of 84

Implement apartment level temperature controls through the use of two way temperature control valves that modulate HHW flowrate in each section of fin radiation in accordance with room space temperature. A description of the savings analysis is provided in Attachment D. FIM #13 Vanderbilt Pipe & Valve Insulation There are significant areas of uninsulated piping and accessories in the basements at Vanderbilt Terrace. Adding thermal insulation to the piping and valves at these buildings will reduce the losses of the heating system and save boiler energy. A detailed analysis including a list of observed sections of uninsulated pipes is provided in Attachment D. 4.3 Building Envelope Improvements At all sites, building envelope improvement will be performed to reduce unintentional air infiltration and the corresponding heating energy. FIM #14 Stonequist Apartments Building Envelope At Stonequist Apartments, specific air sealing activities will include sealing building openings and piping penetrations, installing weatherstripping and sweeps on exterior doors, sealing roof ventilators, and sealing piping penetrations among other areas. A detailed analysis showing the areas and quantities to be sealed are provided in Attachment D. FIM #15 Jefferson Terrace Building Envelope Thermal imaging performed at Jefferson Terrace revealed that the exposed above ground portion of the basement walls and the perimeters around exterior doors were major sources of heat loss. The basement block walls currently have no insulation and the band joist areas are minimally insulated at the front and rear with fiberglass insulation. The band joist areas at the ends of the buildings are not insulated. The building envelope improvements that will be performed will include insulating basement wall and band joists and installing weatherstripping and replacing worn door sweeps on exterior doors. The basement wall and band joist insulation will use 2 thick rigid board insulation secured in place with spray foam to reduce heat loss and infiltration. The insulation will extend from the top of the basement band joist down to two feet below grade. Door sweeps and weatherstripping will be installed on all exterior doors to reduce infiltration. The savings calculation and assumptions are provided in Attachment D. Saratoga Springs Housing Authority IGEA Report - Page 25 of 84

4.4 Low Flow Plumbing Fixture Upgrades Existing plumbing fixtures (aerators, showerheads, and water closets) installed throughout all three sites were found to be standard high flow models. By replacing these with new low flow models the SSHA will result in significant water and energy savings. The analysis of savings for installing low flow plumbing fixtures is discussed in the following FIMs. FIM #17, 20, & 23 Stonequist Aerators, Showerheads, and Water Closets Plumbing fixtures in Stonequist Apartments have rated flows of 1.5, 2.0 or 2.2 gpm for kitchen and bathroom faucet aerators and 2.0 or 2.5 gpm for showerheads. Most showerheads at Stonequist apartments have been replaced with handheld models by tenants. Water closets observed at Stonequist Apartments were either original to the building from 1970 or had been replaced with 1.6 gallon per flush (gpf) models. The average water usage of water closet per flush is 3.5 gpf based on a sample of measurements. All plumbing fixtures at the site will be replaced with new low flow models: 1.5 gpm aerators for kitchen faucets, 1.0 gpm aerators for bathroom faucets, 1.5 gpm handheld showerheads, and 1.28 or 1.0 gpf water closets. In addition to water savings, this measure will reduce domestic hot water consumption and natural gas usage. The analysis of savings and fixture quantities are provided in the detailed analysis in Attachment D. FIM #18 & 21 Jefferson Terrace Aerators and Showerheads Plumbing fixtures at Jefferson Terrace have rated flows of 2.0 or 2.2 gpm for kitchen and bathroom faucet aerators and 2.5 gpm for showerheads. Water closets observed at the site were 1.6 gpf models. The high flow aerators and showerheads will be replaced with new low flow models: 1.5 gpm aerators for kitchen faucets, 1.0 gpm aerators for bathroom faucets, 1.5 gpm showerheads. The existing water closets will not be replaced as part of this project. In addition to water savings, this measure will reduce electric usage for domestic hot water. The analysis of savings and fixture quantities are provided in the detailed analysis in Attachment D. FIM #19, 22, & 25 Vanderbilt Aerators, Showerheads, and Water Closets Plumbing fixtures at Vanderbilt Terrace have rated flows of 2.0 gpm for kitchen and bathroom faucet aerators and 2.5 gpm for showerheads. Water closets observed at the site were either 1.6 or new 1.28 gpf models. The high flow fixtures at the site can be replaced with new low flow models: 1.5 gpm aerators for kitchen faucets, 1.0 gpm aerators for bathroom faucets, 1.5 gpm showerheads, and 1.0 gpf water closets. In addition to water savings, this measure will reduce domestic hot water consumption and natural gas usage.
