Michigan's largest geothermal system cuts HVAC costs by 35%

摘要

Sag-inaw Valley State University (SVSU) here is home to the largest closed-loop geothermal pond system in the state of Michigan. Built into a 6.75 acre, 2.2-million gal. retention pond with an average depth of 13-ft., the geothermal system will heat and cool the university's Crystal M. Lange Health and Human Services building, scheduled to be completed this summer, and is expected to cut total building energy costs by approximately 35% per year - an estimated $63,000 per year in energy savings.
