Solar energy system performance evaluation: Summerwood Associates, House G, Old Saybrook, Connecticut, June 1980-May 1981
Summerwood Associates, House G is a rowhouse condominium in Connecticut. The active solar energy system is designed to supply 62% of the space heating and 100% of the hot water. It is equipped with flat plate collectors with pyramidal optics reflectors, a 600-gallon concrete storage tank, and an auxiliary system consisting of a dual-source heat pump with electrical resistance heater. The solar fraction of space and water heating were 36%, substantially less than was expected, due to less solar energy being collected than was calculated. The solar savings ratio, conventional fuel savings, system performance factor, and solar system coefficient of performance are also given as well as outdoor temperature, heating degree-days, and daily insolation. The performance of the total system and of the collector, storage, hot water and space heating subsystems is analyzed, and the system operating energy, energy savings, and weather conditions are reported. The system is described and the sensors used are discussed. (LEW)
