Sherman Hospital


Sherman Hospital's 645,000 square foot, 255-bed facility features a 2400-ton lake coupled closed loop system, and is one of the world's largest lake-coupled systems.


After the completion of complete and comprehensive energy analyses and lake loop heat exchanger design for the 15-acre, 18-foot deep lake, the geothermal system utilizes 176 heat exchanger grids and more than one million feet of polyethylene pipe to provide 30% to 40% in energy savings of $1 million annually.
