No Meeting May 29 – Memorial Day Holiday

NEXT MEETING June 5 - "Geothermal Heat Pump Systems in the Tennessee Valley" - David Dinse, Tennessee Valley Authority

The presentation will touch on the conceptual basics, challenges, economics, and practical hands-on experiences of geothermal heat pump systems. Conditioned space in the Tennessee Valley is growing to over 10 million square feet. A recent study by the U.S. Environmental Protection Agency showed that geothermal heat pumps (geoexchange) generally have the lowest life-cycle cost and the lowest impact on our environment. Consumers rank their comfort and satisfaction with geoexchange systems higher than all others. While a higher initial investment is required, the investment is paid back through low energy bills (enhancing resale value), excellent family safety, and real comfort. (www.geoexchange.org)

David Dinse is Project Manager of Emerging Technologies in Tennessee Valley Authority's Research and Technology Applications. He is also Past President of Tennessee Valley Chapter of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

Location: The Tallan Cellar Restaurant, in the basement of Regions Bank building on the corner of M. L. King and Carter Sts, Chattanooga, TN 37402
