Delivering heating and cooling using ground sourced heat pumps has been around a long time. Traditionally they have utilized geothermal loops installed within expensive purpose made boreholes drilled to 500 ft (150 m) or laid horizontally and located in areas surrounding the site that effectively sterilizes the site from being used for future buildings. Geothermal loops can also be installed in lakes, rivers and even in the very foundations that support a building. The latter solution provides multiple benefits. It not only makes for a lower install cost but also provides an important additional use for the foundations. Also, an energy foundation solution provides a very valuable long-term energy source that helps deliver a low to zero carbon Geothermal loops installed within foundations Modular rooftop heat pumps connected to energy foundations DEEP FOUNDATIONS * NOV/DEC 2022 * 83
