The Wood Road School Solar Project of the Ballston Spa Central School District is a 216,000 square foot (136,510 square feet of solar conditioned space) combined elementary and middle school located in New York. The solar energy system was designed to supply 64% of the space heating and 88% of the hot water. The system is equipped with 15,389 square feet of one type of flat-plate collector panels and 6650 square feet of another type. Storage is in two 15,000-gallon storage tanks, and auxiliary heating is by electric resistance strip heaters. Monthly performance data are tabulated for the overall system and for each type of collector, storage, domestic hot water, and space heating subsystems. Also tabulated monthly are weather conditions, energy savings, operating energy, and coefficients of performance. Also provided are graphs of collector array efficiency vs the difference between the fluid inlet temperature and ambient temperature divided by insolation. System operation is illustrated by graphs of collector array inlet/outlet temperatures and ambient temperature and typical building loop temperatures vs time for a typical day. Also graphed are the system operating sequence and the solar energy utilization and energy losses. (LEW)
