Going Underground on Campus features examples from more than 160 campuses in 42 states, examining ground-source heat pumps, direct geothermal, aquifer and lake-based, geothermal electricity, and earth-sheltered buildings.

This guide finds that energy savings over conventional heating and cooling systems on campus range from 50 to 75 percent for ground-source heat pumps, 30 to 40 percent for earth-sheltered buildings, and even more for direct use geothermal (which can also cover electricity). Going Underground on Campus is produced by National Wildlife Federation in partnership with the Geothermal Energy Association, GEOExchange: The Geothermal Heat Pump Consortium, and APPA: Leadership in Educational Facilities.
