Instead of burning fossil fuel for heating and air conditioning, GeoExchange systems utilize ground temperature and electric technology for its “two-for-one” system.

“This highly efficient technology makes sense for educational institutions for a number of reasons,” said Ed Mayberry, president of PEPCO, an energy services subsidiary of Potomac Electric Power Co.

“The system provides a high comfort level and is the most efficient way to heat and cool buildings with a single system. Maintenance is easy and low-cost due to fewer moving parts, and the underground portion of the system has a life expectancy of more than 50 years.”

Citing the need to look for alternative energy sources, Catawba College is considering adding the system to other campus buildings.
