SPONSORED CONTENT Condominium Residents Save Money, Lower Carbon Footprint, and Increase Energy Security with CHP uilt in 1964, the St. Tropez holds the unique distinction of being the first condominium building in Manhattan, New York. Despite that distinction, in 2013, the 301-unit and 34-story building was in need of a comprehensive energy upgrade to improve its overall efficiency, sustainability, and energy resiliency in response to occupant environmental concerns and concerns over power outages. After several engineering studies by H.L. Zimmerman Architects the building’s board and facility management firm, FirstService Residential, had a clear picture of the needed updates, which included replacing the building’s boilers and absorption chillers. Among several potential solutions identified by the architect and facility manager, the board’s unanimous decision was to install two Tecogen InVerde 100 kW Combined Heat and Power (CHP) units and a new absorption chiller. The decision was made based on the demonstrable environmental impact, quick ROI, and resiliency the upgrades would yield. In 2015, the two Tecogen InVerde units went online and began B to deliver reliable, clean electricity and hot water at over 80% efficiency. Since then, during winter months, heat generated by the system has been recovered for domestic hot water and space heating. During summer, the same heat now powers absorption chillers to provide cooling to residents. The 200 kW system has the added benefit of being able to power the building during outages. Environmentally, the ultra-clean InVerde units have eliminated 634 tons of CO2 emissions from the environment—a 47% reduc-tion annually, which is equivalent to removing 120 cars from the road or planting 26k trees annually. With a proprietary technology, the natural-gas burning InVerde units have extremely low emissions, exceeding the nation’s most stringent California Air Resources Board regulations. Financially, the CHP units save residents approximately $155,000 annually. While the total project cost was over $930k, the building qualified for over $450,000 in New York State Energy Research & Development (NYSEDRA) incentives, which has helped defray the cost and improve the project ROI to less than 3 years.
