| Abstract |
Recognizing the economical value and conservation benefits of a renewable energy source, the College of Southern Idaho has taken steps to tap a known geothermal aquifer below its campus. In 1978, a well was drilled on campus which can provide 100°F water. Using 100°F water as a heat source, electric heat pumps can significantly reduce space heating costs by replacing the existing electric boilers. In addition, the geothermal resource can be used directly for preheating domestic hot water; swimming pool heating; and secondary uses such as green houses, warm water fish ponds, tree nurseries, alternative energy demonstration projects, and others. A new campus building is now being designed to use the 100°F water directly in space heating coils without any temperature boosting. Additional wells can be drilled to provide sufficient energy for present and future campus facilities. Relatively low cost additions to an initial distribution system can provide extremely low cost heating for future campus facilities which well be designed to directly utilize the geothermal resource. |
