Edgerton Hospital and Health Services, built as a green building in 2011, installed a vertical bore geothermal system that uses the earth’s temperature to heat and cool the 60,000 square-foot complex. With an incentive from Focus on Energy and after five years of operation and savings on natural gas bills from $14,000 to $450 per month, the $850,000 geothermal system was paid off. The hospital is the first hospital in Wisconsin, and the first Critical Access hospital in the nation, to use geothermal heating and cooling. Focus on Energy
