Detention facilities present so many design challenges (especially in the area of security), that achieving LEED certification has rarely been considered. Now that paradigm is changing. The U.S. Army Corps of Engineers is working to incorporate more energy-efficient technology in their facilities, including geothermal heat pumps. The Ft. Leavenworth project has been designed to achieve LEED certification.

The Architect performed a life cycle analysis for several HVAC systems and determined that geothermal would provide the greatest cost efficiency. Meline Engineering was hired by the Architect to design the geothermal field loop. Meline also collaborated with the Architect on the on the design of the mechanical system, distribution, controls, and integration with the ground loop. Even the large walk-in coolers were connected to the ground loop with water-cooled refrigeration equipment instead of conventional air-cooled rooftop equipment.
