The building scored a 38/100 on the EnergyStar benchmark. Altanova inspected the typical residential units and documented existing conditions including: installed electrical appliances, flow rates of plumbing fixtures (both hot and cold water), windows, radiators, air conditioners, lighting, smoke and CO2 detectors, ambient temperature, air quality and humidity. Audit recommendations, implemented scope of work, and reasons for selecting specific energy and water efficiency measures: Adding a Panorama (8 Mil hilite 70) window film on the south windows will reduce total solar energy coming into the building by 55% and eliminate 99% of UV rays. The film allows the visible light through and will not change the appearance of the building from either inside or out. The window film can achieve a savings of 10%.

4 Replace the common area Annon RTU (EER of 11.7) with a more energy efficient unit that has an EER of 18. This would provide a savings of 40% Add a VFD to the primary water loop, providing a savings of 50%. Add electronic descaling to the primary loop, providing a savings of 10%, and also reducing maintenance costs and time. Replace the current halogen bulbs with a more energy efficient bulb that would provide the same amount and quality of light. This will not change any of the lighting characteristics, and will reduce the amount of energy consumed by the bulb and increase the life of the blub from 2,500 hours to 6,000 hours and reduce the wattage by watts depending on the selection Install infrared sensors in the bathrooms to control the exhaust fans to save energy and also reduce the noise pollution created by these fans. This can achieve a savings of 79% in energy Place the elevator motor on a VFD, which will insure energy reduction and insure a smooth ride this will achieve a savings of 50% Conformance to originally proposed schedule and budget: Please select which of the following best describes the nature of the efficiency work: Standalone energy and/or water efficiency upgrade Energy and/or water efficiency improvements as part of comprehensive capital work Pre-Retrofit Savings Projection vs. Actual Savings Metric Projected (Pre-retrofit) Actual (Post-retrofit) Total building $ $ savings % reduction 30 % reduction 25 Electric savings $ $ % reduction 32 % reduction 26 Fuel savings $ 9220 $ % reduction 10 % reduction 3 HDC NYCEEC Energy Retrofit Loan Program 4

7 Number of buildings: 1 Gross square footage: Number of units: 116 Number of floors: 11 Year constructed: 1969 Retrofit date (start to completion): Please select one for each of the following: Heating Fuel Natural Gas Other (please specify): Heating Distribution Hot water Other (please specify): Electric Metering Master-metered Other (please specify): Please select all that apply: Market Mitchell Rate Affordable Lama Rental Condo Co-op Project Information Firm's role: A Level 3 audit was conducted. Building energy use was modeled using TREAT. The recommended measures were projected to save an estimated 35,000 therms per year of natural gas and 52,000 kwh per year of electricity. The projected savings of $50,800 represented a 16% reduction in annual energy costs for a simple payback period of 12.9 years. After adjusting for the difference between the list of recommendations and the measures that were actually implemented, projected savings were adjusted to 35,000 therms per year of natural gas and kwh of electricity (i.e., a kwh per year increase in electricity), for a total of $31,000 per year, a 10% reduction in annual energy costs. Audit recommendations, implemented scope of work, and reasons for selecting specific energy and water efficiency measures: The recommended measures included replacement of an old, inefficient absorption chiller with a high efficiency air-cooled chiller, replacement of old steam boilers with hydronic condensing boilers, a new furnace and overhead door for the maintenance area, a swimming pool cover and heat recovery ventilation for the swimming pool area, top-loading clothes washers, and lighting improvements. Conformance to originally proposed schedule and budget: NYSERDA contracted with Taitem to evaluate the energy savings resulting from implementation of energy conservation measures. The energy conservation measures from the audit that were installed were: Replace steam boilers with condensing hydronic boilers, replace absorption chiller with high efficiency electric chiller, install swimming pool cover, new overhead door for maintenance area. HDC NYCEEC Energy Retrofit Loan Program 7

8 The recommended lighting improvements, top-loading washers, and new furnace for maintenance area were not implemented, and the swimming pool cover was used only briefly because the operating mechanism was awkward for tenants to use. In addition to the recommended measures that were implemented, the building's original double-glazed windows were replaced with new double-glazed windows. Window replacement had an SIR<1 and was therefore not recommended in the audit. The projected savings below have been adjusted to remove the savings projected for recommended measures that were not installed. The actual savings reported below have been adjusted to remove savings attributable to the window replacement.

The 1969 steam-powered absorption chiller was oversized, inefficient, and past the end of its anticipated life. Projecting savings was complicated by the need to adjust for historic breakdowns and steam leaks from the HDC NYCEEC Energy Retrofit Loan Program 8

9 chiller. We expected gas usage to decrease and electric use to increase when the recommended measures were implemented. Gas usage decreased as predicted. Use of electricity also decreased, because during the design phase it was determined that the original circulation pumps were oversized. Replacing them with smaller pumps saved significant pumping energy. HDC NYCEEC Energy Retrofit Loan Program 9
