New York Studies First U.S. Subway Heat Network at 96F Station

3 articles · Updated · nyc.gov · Jun 29

Summary

  • New York City, New York state and the MTA will study a thermal energy network at the Brooklyn Bridge-City Hall and Chambers Street complex, a first for a U.S. transit system aimed at cooling overheated platforms.
  • 96 Fahrenheit average summer temperatures at Brooklyn Bridge-City Hall in 2025 helped drive the plan, which would capture excess subway heat and reuse it to warm nearby municipal buildings in winter.
  • Radiant cooling panels and geothermal boreholes beneath Chambers Street's abandoned center platform would absorb, store and redirect heat, with officials saying the setup could cut delays tied to extreme platform heat.
  • The feasibility contract is expected this fall, with design work starting in early 2027 if geothermal conditions check out; the Chambers Street renewal itself is funded through congestion pricing.
  • Radiant cooling can be 25% to 35% more efficient than traditional air conditioning, making the project part of a broader city-MTA push to harden transit against worsening climate-driven heat.
