Howard, B. D.

Spearfish High School in South Dakota contains 43,000 square feet of conditioned space. Its active solar energy system is designed to supply 57% of the space heating and 50% of the hot water demand. The system is equipped with 8034 square feet of flat plate collectors, 4017 cubic feet of rock bin sensible heat storage, and auxiliary equipment including 8 heat pumps, 6 of which are solar supplied and instrumented, air conditioning units, and natural-gas-fired boilers. Performance data are given for the system including the solar fraction, solar savings ratio, conventional fuel savings, system performance factor and solar system coefficient of performance. Insolation, solar energy utilization and operation data are also given. The performance of the collector, storage, domestic hot water and space heating subsystems, the operating energy, energy savings, and weather conditions are also evaluated. Appended are a system description, performance evaluation techniques and equations, site history, long-term weather data, sensor technology, and typical monthly data. (LEW)
