Geoexchange systems, also known as low-temperature or shallow geothermal systems, utilize the constant temperature just below the earth's surface to heat and cool buildings. These types of systems use mature, proven technologies and have been successfully used around the world for years. They are extremely efficient, providing three to four units of free energy for every one unit of energy consumed. Geoexchange systems can be used in residential, commercial and industrial buildings and have many technical, environmental and economic benefits.

This fact sheet, the third in the Making Renewable Energy a Priority series, introduces the reader to the different types and configurations geoexchange systems, and the technical and economic benefits of using this free energy resource from the earth.
