From Airports to Elementary Schools, New Examples of Geothermal Heating & Cooling Sites Emerge - CleanTechnica

The U.S. Department of Energy (DOE) Office of Geothermal has expanded its Geothermal Heat Pump (GHP) Case Study Yearbook with five new examples of geothermal heating and cooling systems across the United States. These case studies, developed by the National Laboratory of the Rockies in collaboration with the respective sites, highlight diverse applications of GHP technology in residential communities, schools, airports, colleges, and grocery stores. The updated database now features over 20 documented locations demonstrating the effectiveness of GHPs in leveraging stable subsurface temperatures to reduce energy consumption for heating and cooling. Key new case studies include The Town at Trilith in Georgia, one of the largest geothermal residential communities with 750 homes using individual GHP systems, and Spring Mills Primary School in West Virginia, part of a district-wide upgrade that cut energy use by 75%. At Louisville Muhammad Ali International Airport, geothermal wells beneath the airfield support heating and cooling for the terminal, projected to save $400,000 annually. Central
