The Crown Realty I site is a small office building in Colorado. Its active solar space heating system is equipped with 907 square feet of liquid flat-plate collectors, 2500-gallon water storage tank, and several solar-assisted heat pumps with electric resistance strip auxiliary heating. Solar system performance data given include the solar fraction, solar savings ratio, conventional fuel savings, system performance factor and coefficient of performance. Although the solar fraction was 29%, the solar savings ratio reflects a 9% penalty due to operating energy expense. Monthly system performance data are tabulated, as well as performance data for each subsystem - the collector, storage, and space heating subsystems. Monthly solar operating energy, energy savings, and weather conditions data are also tabulated. Typical system operation data are also graphed and discussed, as is solar energy utilization. Among the appendices are a system description, performance evaluation techniques, typical monthly data, long-term weather data, and a brief discussion of the sensor technology. (LEW)
