Book excerpt: This feasibility study and preliminary conceptual design effort assesses the conversion of Colorado School District 50 facilities - a high school and gym, and a middle school building - at Pagosa Springs, Colorado to geothermal space heating. A preliminary cost-benefit assessment made on the basis of estimated costs for conversion, system maintenance, debt service, resource development, electricity to power pumps, and savings from reduced natural gas consumption concluded that an economic conversion depended on development of an adequate geothermal resource (approximately 150°F, 400 gpm). Material selection assumed that the geothermal water to the main supply system was isolated to minimize effects of corrosion and deposition, and that system-compatible components would be used for the building modifications. Asbestos-cement distribution pipe, a stainless steel heat exchanger, and stainless steel lined valves were recommended for the supply, heat transfer, and disposal mechanisms, respectively. A comparison of the calculated average gas consumption cost, escalated at 10% per year, with conversion project cost, both in 1977 dollars, showed that the project could be amortized over less than 20 years at current interest rates. In view of the favorable economics and the uncertain future availability and escalating cost of natural gas, the conversion appears economicaly feasible and desirable.

This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This conceptual engineering study has examined the feasibility of implementing geothermal space and water heating systems at the high school and elemetary school facilities (Surprise Valley School District) in Cedarville, California. The two geothermal wells, which would serve as the energy source for the project, have more than sufficient productive capacity of fluids at temperatures to efficiently heat both school complexes. The wells produce fluids in the temperature range l20-126°F. Peak flow requirements are 66 gpm at the high school and 43 gpm at the elementary school. Average flow requirements are about 25 and 17 gpm, respectively. The fluids are exceptionally clean, at about 178 TDS. Seven engineering design approaches were examined for their technical and economic merit for the proposed application (four for the high school building and three for the elementary school building). The optimum design for the high school is based on the direct use of geothermal fluids in cabinet heaters and unit heaters. The system would displace the schools current reliance on 8-10,000 gallons of fuel oil annually. The optimum design for the elementary school would involve the direct use of geothermal fluids in existing hot water slab systems and the addition of water coils in electrical resistance equipment in the north classroom annex. The geothermal heating system would replace the schools current reliance on about 4200 gallons of fuel oil and 42,885 KWH of electric resistance heating annually. At both installations, existing boiler systems would be retained for backup and infrequent peaking requirements. The cleanliness of the geothermal fluids will permit surface discharge at both project locations. A 25-year life cycle cost-benefit analysis was completed for each school system and the project as a whole. At the elementary school, the savings stream has a Net Present Value (10% DF) of $107,612 on capital expenditures of $73,991 and a 12-year simple payback. At the high school, the savings stream has a Net Present Value of $94,595 on capital expenditures of $118,894 and a simple payback of 22 years. The economic performance of the combined project has a discounted savings stream of $202,207 on capital expenditures of $192,885 and a simple payback of 13-16 years, depending on how closely actual current fuel oil consumption corresponds with predicted heat loads and fuel consumption.

Book excerpt: This project which was funded by the California Energy Commission called for the construction of a geothermal well. Construction of the geothermal well was for the purpose of space heating portions of facilities owned by the school district. The down hole heat exchange method was for utilization of the natural heat to be produced by the well and retrofitting the existing heating system to the down hole heat exchanger.
