Ground Source Heat Pumps CXS

The mission of the Ground Source Heat Pumps (GSHP) Center of Expertise in Sustainability (CXS) is to provide knowledge sharing for geothermal technology, most specifically but not limited to ground source heat pumps. The GSHP CXS functions to support project development teams from the concept generation phase through the installation phase of their ground source heat pump projects. The GSHP CXS also assists with troubleshooting design and installation deficiencies in the ground loop and building loop for ground source heat pump projects.



A geothermal wellfield was sized for 100% of the building load for the Sustainment Brigade Administrative Facility, Fort Campbell, KY. The wellfield consists of 69 boreholes, each with a depth of 415 feet. The facility is 30,900 square feet with air handlers and variable air volume (VAV) boxes with hot water reheat served by water-to-water heat pumps. The project is designed for 36.97% energy cost savings from ASHRAE 90.1-2007 baseline and 49.68% energy consumption savings from ASHRAE 90.1-2007 baseline without process loads. The facility is designed to achieve LEED Gold Certification.
