GHPs, on the other hand, use the thermal energy stored in the upper portion of the earth’s crust to heat or cool a building, replacing conventional boilers and air-conditioning systems.

They tap into these reserves of heat and use them to produce steam, which then drives a turbine, thus producing electricity. Geothermal power plants-known in the industry as hot rock geothermal-are large installations built (in this country) mostly around the Rocky Mountains and the Sierra Nevada range, where extremely high temperatures from the Earth’s mantle can be found relatively close to the surface. The first thing that any expert on the technology will tell you is that geothermal systems for buildings, also known as geothermal heat pumps or ground-source heat pumps (GHPs), are not the same thing as geothermal power plants. While significant strides have been made to change this picture by designing more efficient mechanical systems, increasing thermal performance, and developing on-site generation of renewable energy-all important and admirable advances-perhaps the most promising resource available to architecture may be found within the very terra firma upon which structures sit, in the form of geothermal systems. Whether they draw on the electric grid to beat the heat during summer or burn fossil fuels on site to fight the cold of winter, buildings, on the whole, make SUVs look environmentally friendly. Department of Energy estimates that roughly 40 percent of the nation’s overall power consumption goes toward heating and cooling our homes, offices, and institutions. In the war to cut down on our energy usage, a frontline has been drawn in the field of temperature control.
