Ground Source Heat Pumps

Also commonly called ‘geothermal’ heat pumps, ground source heat pumps use the relatively stable temperature of the earth to serve as a heat sink for the rejection of heat in the summer and the supply of heat in the winter. These systems can dramatically reduce a building’s energy use and carbon footprint. The LEED Gold certified Graduate Housing at Columbia Theological Seminary makes use of this largely invisible energy-saving technology. This technology was a key energy efficiency measure contributing to the project’s projected 50 percent reduction in energy use.
