Rymark I, Rymark II, and Rymark III, Frederick, Maryland solar-energy-system performance evaluation, May 1981 through March 1982

Technical Report ·
OSTI ID:6951827

The Rymark I, Rymark II, and Rymark III sites are single family Maryland residences whose respective passive solar energy systems are designed to supply 16%, 28%, and 42% of their heating loads. Each is equipped with a 24,000-Btu heat pump for auxiliary heating. Rymark I is equipped with 92 square feet of south-facing double-glazed windows. Rymark II is equipped with 150 square feet of south-facing triple-pane windows. Rymark III is equipped with 227 square feet of south-facing triple-pane windows with blinds and 560 square feet of phase-change ceiling tile system. The actual solar fractions achieved by the Rymark I, II, and III systems are 14%, 17%, and 20%, respectively. Monthly performance data are tabulated and compared for the overall system of each house, and for the collector, space heating, and storage subsystems. For each house and for each month, the insolation, ambient air and building temperatures, and auxiliary energy used are graphed vs. day of the month. These data are also graphed vs. hour of the day for a typical day. Monthly data are also tabulated for the environment in the passive systems, energy savings, and weather conditions. (LEW)
