Think geothermal can’t work for an urban site? The Center for Architecture, located in the Greenwich Village neighborhood of Manhattan, proves a loop field can hide beneath a busy borough.
Installed in 2003 during a renovation, a geothermal heat pump system draws groundwater from two 1,260-foot-deep wells that were drilled through the sidewalk at the headquarters of the AIA New York Chapter. It provides heating and cooling for the 15,000-square-foot building, which is comprised of offices and open spaces.
The geothermal system itself cost $100,000, which was largely offset by a grant from NYSERDA, and had a payback period of three years. It is one of the first installations in New York City.
