Energy Retrofit Loan Program Service Provider Profile General Firm Information Steven Winter Associates, Inc.(SWA) 307 Seventh Avenue, Suite 1701, New York, NY, 10001 Primary Contact: Marc Zuluaga, mzuluaga@swinter.com (212-564-5800 x114) Secondary Contact: Erica Brabon, ebrabon@swinter.com (212-564-5800 x118) Website: www.swinter.com Year established: Number of employees:80 1972 Firm Experience Our success stems from a 40-year track record of staying at the forefront of an industry that has recently become crowded with newly-formed energy start-ups and older firms that have recently become green. We take pride in the experience of our highly-trained staff and their ability to plan and execute successful projects customized to the needs and goals of our clients. In the last five years, SWA has conducted building evaluations of 30M square feet of existing multifamily buildings with facilities ranging from under 5 units to 17,000 units. While many energy audting firms do not even have licensed engineers on staff, SWA has a dedicated group of PE's that specialize in translating energy audit recommendations into reality. Upon completion of our audits, we provide turnkey Mechanical, Electrical and Plumbing design, third-party construction oversight, commissioning, training and long term performance monitoring services, customized to meet the needs of our clients and their projects. And since many of the most cost-effective and sensible opportunities in buildings involve fine tuning existing systems, we have extensive experience retrocommissioning to optimize building operations. Our unique and comprehensive approach to a wide-range of challenges has led SWA to receive the following industry recognitions: - The only multifamily auditing firm selected for the (post-sandy) NYC Building Resileincy Task Force convened by Mayor Bloomberg to develop standards to improve building performance after exteme events. - The only NYC energy auditing firm selected by the Urban Green Council for a prestigous "EBie" award for exemplary energy savings in a retrofit project. - Recipient of multiple research grants from NYSERDA & HUD to pilot and then refine a practical approach to fix ventilation systems in NYC multifamily buildings. - Selected by NYSERDA to develop a "Multicogen" screening tool for the assesment of Combined Heat and Power (CHP) savings potential in NYSERDA Multifamily Perofrmance Program projects - Selected by Deutsche Bank to lead a groundbreaking study measuring actuall energy HDC NYCEEC Energy Retrofit Loan Program 1

As part of an energy audit, SWA identified the toilet and kitchen ventilation system that was drawing excessive amounts of air out of the building as the key culprit to the high bills. A conventional energy audit recommendation would have been to turn off the fans in the middle of the night at the expense of indoor air quality. Instead, SWA HDC NYCEEC Energy Retrofit Loan Program 3
recommended recommended a novel approach to rebalancing the ventilation system to both reduce energy use and improve air quality. SWA provided turnkey design specification and commissioning services to support the succesful execution of this project. The results realized at Carlyle Towers have spurred this project to be replicated in dozens of other NYC metro area buildings over the past few years over which time SWA has worked with a range of contractors to continually improve and refine the ventilation retrofit process. This projected was recognized for innovation with an "EBIE" award by the Urban Green Council and informed the development of an owners guide for Improving Ventilation in existing multifamily buildings written by SWA and pubblished by the National Center for Healthy Homes: www.practitionerresources.org/showdoc.html?id=67355&topic=weatherization&doctype =Spreadsheet The kitchen and bathroom exhaust ventilation system was upgraded with Constant Airflow Regulators (CARs) to balance ventilation flows and the AEROSEAL system to reduce shaft leakage. AEROSEAL works by sealing holes from the inside with a polymer based sealing agent. As a result of the retrofit, balancing from floor to floor at Carylyle Towers was dramatically improved and 90% of the existing duct leakage was sealed. Pre and post balancing results for this retrofit were evaluated as part of a HUD study: www.toolbase.org/pdf/fieldevaluations/car-fieldeval-final.pdf The innovative shaft upgrade also allowed SWA to specify 24 new downsized roof fans; lowering roof fan electricity use by over 50% and reducing maintenance requirements. Despite being the first building in the country to implement this ventilation retrofit, this project met original budget and schedule goals in large part because of the strong partnership and working relationship between Legow and SWA.

It is always a good sign if, after competing energy upgrades at a building, the utility sends someone to investigate a meter for "tampering" due to unusally low readings. This is exactly what happened at Williamsburg Court after a succesful retrofit. SWA provided comprehensive services to St. Nick's Alliance including energy audit, mechanical design of the new boiler plant and commisisoning of all energy retrofit. Prior to the upgrade work, heating and domestic hot water was provided by a eight atmospheric gas boilers which are very common in NYC even though they result in huge "standby" lossess when boilers are off. SWA recommended replacing the existing boilers with sealed combustion boilers to meet the space heating and hot water needs of the building. This new boiler plant was selected to be compatible with the existing chimney to minimize costs. The new controls were chosen to optimize energy performance while at the same time being simple and useful to the on site mainteance staff. An electronic mixing valve was specified to tightly control the temperature of domestic hot water supplied to the kitchens and bath taps. To compliment the boilers and provide residents with an additional level of comfort control, thermostatic radiator valves were installed in all apartments. Additional energy measures including air sealing, new windows, toilet and kitchen ventilation system balancing, bilevel lighting in corridors and stairwells and ENERGY STAR refrigerators. The active engagement of SWA's design engineering group in the audit process resulted in practical and effective recommendations which allowed the project to come in on schedule and on budget.

While many energy auditors, focus attention on new fancy boiler control panels, SWA worked with the co-op to attack the heart of the problem by fixing the distribution of steam throughout the building. SWA conducted an HDC NYCEEC Energy Retrofit Loan Program 7
energy audit and provided design and commissioning services to support the heating system upgrade that significantly reduced fuel use while also improving comfort and reducing mainteance costs. The heating system upgrades included adding orifices plates and air vents to improve the steam distribution, inserting radiant barriers behind every radiator to reflect more of the heat into the building, and installing a new boiler control that responds to the interior apartment temperatures as well as the outdoor temperature. Orifice plates eliminated the need for steam traps in 90% of apartments, reducing future maintenance costs and headaches. SWA projected these upgrades would save the building 19% of their heating fuel usage, or approximately $10,000 at the then current oil prices. SWA analyzed 250 Cabrini s utility bills for the postretrofit winter and found that the building actually saved 21% of their heating fuel usage, even more than projected. In the same time frame, the building s cost for oil rose by 50%, which makes the improvement worth even more to the coop, dropping the simple payback period from a projected 5.7 years down to 4.5 years. This project came in on time and on budget. Heating system upgrade specifications were developed by SWA that clearly communicated project requirements and incorproated important performance based specifications that protected the interests of the owner. These specifications allowed plumbers that the building was familiar with and plumbers that SWA had succesfully worked with in the past to bid on the work.
