New York’s Subway Heat Turned into Winter Warmth: The City’s First Transit Thermal Energy Network Pilot Turning platform heat into usable energy — what the Chambers Street and Brooklyn Bridge–City Hall pilot means for urban energy systems New York City has launched a study to design and test a Thermal Energy Network (TEN) that would capture excess heat from two of Lower Manhattan’s hottest subway stations and reuse it to heat nearby municipal buildings. The proposed pilot, centered on the Brooklyn Bridge–City Hall 4/5/6 complex and the Chambers Street J/Z station, is notable for being the first time TENs are being considered inside a U.S. transit system. The plan pairs radiant cooling on platforms with geothermal borehole storage under an abandoned center platform at Chambers Street, converting otherwise wasted heat into a supply that can be stored seasonally and delivered to surrounding municipal facilities during colder months. This initiative sits at the intersection of urban heat r...
