New York’s largest geothermal residential project has topped out on the Greenpoint waterfront. Located at 1 Java Street, the two-tower development features 834 rental units, a climate-resilient shoreline, and 13,000 square feet of retail space. Slated for completion in 2026, the all-electric project’s sustainable features are expected to reduce annual carbon emissions from heating and cooling by 53 percent compared to traditional residential systems.
Designed by Marvel, the two towers, measuring 37 and 20 stories, are situated along a full city block facing the East River. The towers are connected by a mid-rise podium with frontages on India, Java, and West Streets.
A new public waterfront esplanade will seamlessly integrate the development with the surrounding area. This includes direct access to the India Street Pier, which was revitalized as part of the project and is serviced by the East River Ferry. Additionally, a “living shoreline” will be installed to protect the site from future flooding events.”
By utilizing a “vertical closed-loop geo-exchange system,” the all-electric building will eliminate the carbon emissions associated with natural gas use. The project is targeting LEED Gold certification, WEDG Waterfront Certification, Fitwel Certification, and Energy Star Certification, according to Lendlease.
Lendlease acquired $4 million in funding from the state’s Energy Research and Development Authority to build the geo-exchange system at 1 Java Street.
“We are proud to reach this significant milestone of structural completion for a project that establishes a new model of equitable and sustainable urban development,” Meg Spriggs, managing director of Development, Americas at Lendlease, said. “1 Java Street aligns with Lendlease’s long-term investment strategy in the Americas, focused on properties that improve the vibrancy of the surrounding community while also delivering value to investors.”
When it opens, 1 Java Street will become the city’s largest multi-family geothermal project, surpassing the previous record held by 1515 Surf Avenue in Coney Island, which topped out in May 2023. Developed by LCOR and designed by STUDIO V Architecture, the 16-story building’s geothermal system uses the Earth to heat and cool the property and power its water systems.

Where are the geo-exchange bores located? Are they under the building – any issues with the building foundations? Are they in a designated well field? What is the total tonnage of the building? What is the typical tonnage of each residential unit? Do they supplemental boilers or cooling towers/condenser for heat load balance between summer cooling and winter heating?
