Spotlight on Geothermal

Lipscomb University

Geothermal heat pumps for the university's Burton School of Pharmacy building, three new dorms, and the Ezell Center will save the school more than 15% on their total utility costs.

To maximize space, Lipscomb installed the series of pipes, called a loop, under a new softball field.  The vertical installation consisted of 144 boreholes drilled to a depth of 300 feet.  The boreholes were buried 25 feet apart to minimize ground warming and increase the longevity of the system.

"Using geothermal as an energy source is not only a sound long-term investment, but also a decision that exemplifies environmental responsibility, which sends an important message to our students," says Don Johnson, David Lipscomb director of facilities.

Despite the higher upfront costs, geothermal heat pumps use less electricity and are much more environmentally friendly than regular heating and cooling systems.  Lack of both year-round sun and constant wind makes geothermal a practical method of alternative energy in Middle Tennessee.
