Seminar Covers Geothermal GeoExchange Systems

Owners and operators of large businesses, institutions, schools and other government buildings can save large amounts of money on heating and cooling costs by taking advantage of the energy available in the ground, according to the coordinators of an upcoming seminar on geoexchange systems.

Grand Junction, Colorado – February 25, 2004 [] The first commercial/institutional “GeoExchange” seminar held in Grand Junction, “Greening Your Bottom Line with GeoExchange,” this Friday, 2/27, at the Two Rivers Convention Center, brings this news in the midst of a cold winter and significantly higher prices for natural gas. “We’re pleased to bring some of the top GeoExchange experts in the state and country to Grand Junction for this event,” said Rose Dowdy of Enlink Geoenergy Services, coordinator of the seminar. Speakers include Thomas Fernandez, Energy Manager of Colorado Springs School District 11, a pioneering institution which has seen GeoExchange cut energy bills by 52% in the first building in which it was installed. Also scheduled to speak is Jon Shonder of the U.S. Department of Energy’s Oak Ridge National Lab. The “GeoExchange” principle has been used for decades and there are more than half a million buildings in the U.S. now using the environmentally friendly technology. With Geoexchange systems, there’s no need to create heat, hence no need for chemical combustion. Instead, the Earth’s natural heat is collected in winter through a series of pipes, called a loop, installed below the surface of the ground. Fluid circulating in the loop carries this heat to the building. Electrically-driven compressors and heat exchangers–the same systems used in your home’s refrigerator– concentrate the Earth’s heat and release it inside the building at a higher temperature. In typical systems, duct fans distribute the heat to various rooms. In summer, the process is reversed in order to cool the building. Excess heat is expelled to the loop, and absorbed by the Earth. Geoexchange systems provide cooling in the same way that a refrigerator keeps its contents cool–by drawing heat from the interior, not by injecting cold air. “In addition to saving energy and money, the GeoExchange systems substantially reduce pollution and can save hundreds of thousands of gallons of water used for cooling in the summer, an increasingly important benefit to Colorado,” Dowdy said. Ward Huffman of the U.S. Department of Energy’s Denver Regional Office, explained other features GeoExchange systems offer business owners “The efficiencies achieved by these (GeoExchange) systems are impressive and allow commercial users to save up to 50 percent over conventional heating and cooling systems, plus they reduce maintenance costs,” said Huffman. The event is free, made possible by the sponsorship of the Colorado Coalition for New Energy Technologies, the Colorado Governor’s Office of Energy Management & Conservation, the Colorado Renewable Energy Association, the Colorado Rural Electric Association, DMEA, EnLink Geoenergy Services, Inc., InterMountain Energy, the National Renewable Energy Lab (NREL), San Miguel Power Association, Tri-State Generation & Transmission, Inc., the U.S. Department of Energy, and the Western Area Power Administration (WAPA). Registration at the Two Rivers Convention Center is at 9:00 a.m., with the seminar running from 9:30 a.m. through 1 p.m., with lunch provided. Additional technical training is available after lunch.
