Geothermal Heat Pumps
The Rankin Technology Building features a geothermal heat pump to help heat and cool the building, that was implemented in 2009. The 265 kW vertical system has over 40 drops that go 400 feet into the ground which saves approximately 2,300 MWh annually. It uses the earth as a heat source in the winter and a heat sink in the summer. This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems.
