320 Boreholes Below Brooklyn: How Geothermal Replaces Fossil Fuels in Cities

* Sign-up for Johnson Controls Webinar: Evolving Building Codes *

The largest geothermal residential building in New York City just opened in Greenpoint, Brooklyn. 834 apartments. 320 boreholes drilled hundreds of feet underground — enough to heat and cool every unit in the building. Even the rooftop pool.

Geosource Energy drilled it. This conversation is about how they did it, and what it takes to build geoexchange systems at scale in dense cities, where there's already a city's worth of infrastructure below: water, gas, electric, telecom, subways, and foundations.

Geoexchange is simple to explain and hard to execute. No combustion. No fuel. Fully electric. The physics are straightforward. The delivery is not.

Building owners choose geoexchange for the operating savings. And for every dollar saved at the building level, the grid saves eight or nine — because geoexchange cuts peak demand when electricity is most expensive and most scarce.

That's a true decarbonization driver. And why cities from Toronto to Boston to New York are leaning in with more to follow.
Geosource has completed more than 400 projects. The infrastructure they install is designed to outlast the buildings it serves. Stan calls it 500-year pipe. He's seen a building come down and the borefield stay put, ready for the next one.
