The Forest City Dillon solar energy system is the Fort Lincoln Senior Village apartment complex in Washngton, DC. The active solar energy system is designed to supply 59% of the hot water, and consists of 2592 square feet of flat plate collectors, 3200-gallon storage tank, and an auxiliary oil-fired boiler. Performance data are given for each month of 1981 for the system overall and for the collector, storage and hot water subsystems. The solar fraction was 28%, far short of the expected 59%. Solar energy saved 3218 gallons of fuel oil at the expense of 4986 kWh of electricity for an overall saving of $3870.00. Other data given include the solar savings ratio, system performance factor, solar system coefficient of performance, auxiliary energy and operating energy used, weather data, system operation sequence, and typical array and storage temperatures. The site and the performance evaluation techniques and equations are described. (LEW)
