The Oakmead Industries solar energy site is a commercial office/manufacturing building in California whose solar energy system is designed to supply 85% of the space heating load and 90% of the hot water load. The system is equipped with 2622 square feet of liquid flat plate collectors, 1675 square feet of Trombe wall, and 6500-gallon steel storage tank. Auxiliary space heating is via two gas-fired heating units, and auxiliary domestic hot water is via electric resistance type water heater. The system was found to have supplied only 50% of the space heating and 47% of the hot water heating load. Also given for the reporting period are the solar savings ratio, conventional fuel savings, system performance factor, and solar system coefficient of performance. Monthly performance data are tabulated for the system overall and for the liquid collector, storage, domestic hot water, space heating subsystems. Typical system operation is illustrated by graphs of temperatures at the collector inlet and outlet and in storage for a typical day, and the system operating sequence and solar energy utilization and losses are graphed.
