Appendices of an appraisal for the use of geothermal energy in state-owned buildings in Colorado. Section A. Alamosa
Two state-owned building complexes have been evaluated within the city of Alamosa: Adams State College and the State Highway Department Buildings. The resource assessment in dicates that 150/sup 0/F may be available at flow rates of 1000 gpm per well, depths of 4000 feet, and possibly under Artesian pressure. Two building retrofit engineering options are evaluated for Adams State College, both of which assume only partial replacement (approximately 50%) of the existing natural-gas-fired steam-boiler system. The two retrofit options for goethermal heating include (1) a high performance central heat pump for boosting the circulating heat water to 200/sup 0/F for space heating and (2) a central heat exchanger for delivery of heating water at 145/sup 0/F. The first option provides for continued usage of the existing hot water heating units in the campus buildings, with the exception of retrofit of the steam units in College Center. The second option provides for the addition of terminal hot water heating units in all of the buildings in order to adapt to 145/sup 0/F heating water. Retrofit engineering for the State Highway Department Buildings provides for the use of a central heat exchanger and the distribution of 140/sup 0/F heating water to all building areas that are presently heated.
