212 W 105th Street, New York, NY

Taitem led a heat-pump conversion project at 212 W. 105th Street, an affordable HDFC co-op building. We believe this is the first such steam-to-heat pump conversion project that was fully monitored, providing post-installation data analysis to validate energy savings.

This building is a 5-story, 10-unit walkup, with 9,690 sqft, of which 10% is common area (vestibule, corridors). The pre-retrofit steam boiler provided both space heating and DHW, with window air-conditioning units providing cooling.

Taitem services included pre-design, design, construction, and post-construction services. Pre-design services included creating a calibrated eQUEST energy model to simulate pre- and post-retrofit performance. , coordinating with Daikin, which donated equipment for the retrofit, and working with Cornell University’s department of mechanical engineering to involve students in an innovative real-world project.
