NYCHA Eastchester and Jackson Houses Geothermal DHW and Heating Upgrade Recognized with Dual Honors
The $65-million pilot project introduced a groundbreaking geothermal system tailored for dense, multifamily urban housing, setting a new standard in sustainable residential infrastructure. The existing traditional fossil-fuel-based domestic hot water systems were replaced with high-efficiency, closed-loop vertical geothermal heat pumps that will supply year-round hot water to 1,745 apartments across 17 multifamily buildings.
Each building required boreholes drilled 500 ft into bedrock to serve as renewable thermal sources. In partnership with a geothermal systems manufacturer, the project team developed an innovative 30-ton dual-compressor heat pump capable of producing domestic hot water at more than 140°F. This design resulted in increased efficiency and stable high-temperature output with a coefficient of performance (COP) of approximately 4—double the typical results at that temperature.
The system’s advanced liquid injection method and double-walled heat exchangers meet stringent health codes and industry performance standards. High-efficiency storage tanks and instant-response mixing valves ensure minimal water waste while meeting critical temperature standards.
Once construction was underway, leaks in legacy piping systems were addressed swiftly through targeted inspections and emergency repairs. Advanced leak detection tools and coordinated scheduling helped maintain project momentum. Despite these and other hurdles, the team delivered the project ahead of schedule and within budget. By switching the apartment complex from gas/oil to geothermal, the project avoids direct greenhouse gas emissions, contributing to long-term environmental resilience. It also protects vulnerable populations from utility price volatility while providing reliable, efficient hot water.
2425 Pacific St, Brooklyn, NY
The new construction 10-story, 254,000 sqf building will house 236 supportive and affordable residential units with ample amenities. 2425 Pacific Street is developed in partnership by Alembic Community Development, Brooklyn Community Housing & Services and Love Fellowship Tabernacle. The residential mix includes 71 units for chronically homeless single adults with a Serious Mental Illness (SMI), a Substance Use Disorder (SUD) or co-occurring SMI and SUD; 71 units for chronically homeless families with children where the head of household has a SMI, a SUD or co-occuring SMI and SUD; and 93 units for individuals and families earning between 30% and 80% of AMI.
Brooklyn Community Housing & Services will provide on-site social services and the ground floor features 6,950 square feet of commercial space to be used for either retail or community programming. The site requires environmental remediation and has entered the NYS DEC Brownfield Cleanup Program.
Financing
NYS Housing Finance Agency; NYC Department of Housing Preservation and Development; 4% Low-Income Housing Tax Credits; Federal Energy Tax Credits and NYS Brownfield Cleanup Program Tax Credits syndicated by Hudson Housing Capital; NYC City Council Resolution A funds from local elected officials; Con Edison Clean Heat Program and NYSERDA.
It is currently the only multifamily building in NYS operating without antifreeze in the closed ground loop, in order to enhance loop field performance, and to further significantly reduce pumping power.
(DHW) loads. System operates without any fossil fuel or electric backup, fully electrified, without any gas lines entering the building.
Funded partially by New York State DHP, the geothermal system sets a new benchmark for energy efficiency. Nominal System Capacity is 220 tons for Heating and Cooling, and 60 tons for DHW.
Loop field consists of 62 Vertical Boreholes spaced 20ft apart and 420ft deep. There are 343 ducted GEO Heat Pumps, and 2 DHW Heat Pumps, all manufactured by Waterfurnace and Climatemaster.
The Pumps for Geothermal Source Water are Wilo MAXO Stratos 3x3-52 ECM, setup in Lead-Standby configuration, consume on average 12 watts per Ton of Capacity.
The Bloomberg Center, NY, NY
Located on Cornell’s new applied tech campus in New York City is one of the largest aspiring net-zero energy buildings in the United States. The Ground Source Heat Pump system consists of 80 boreholes spaced 20 ft. apart, drilled to a depth of 400 ft. It provides the majority of the heating and cooling load for the building. This system, the first of its kind in the US, uses a unique annulus system to increase the efficiency of the ground loop. It takes advantage of river water penetration through the local bedrock which occurs at a major water-bearing fracture at between 300-380 ft., to accelerate thermal dissipation. Endurant seamlessly integrated with the General Contractor on the site, effortlessly managing the logistical complications that arise from working in a city-center location.
St. Vincent Health Sciences Center on the campus of St. John’s University
The newly constructed energy-efficient building that features active learning classrooms, laboratories, simulation facilities, office space, collaborative spaces, and outdoor terraces. It was constructed with environmentally friendly, sustainability features that include geothermal heating and cooling, rooftop solar panels, and high-performance windows designed to reduce thermal loss.
The new building features a holistic and scalable approach to sustainability. It accommodates a series of both campus and New York City sustainability initiatives and contributes to the carbon reduction efforts of the entire University.
