Solar project description for J. D. Evans, Inc. , House B, single family residence, Columbia, Maryland

Technical Report ·
OSTI ID:6427626

J.D. Evans, Inc., House B, is an instrumented single-family residence in Columbia, Maryland with approximately 2250 square feet of conditioned space. The solar energy system has an array of flat-plate collectors with a gross area of 350 ft/sup 2/. Solar energy is stored in the basement in a 1000-gallon steel storage tank. Incoming city water is preheated in a liquid-to-liquid heat exchanger located in the storage tank and then flows into a conventional 40-gallon DHW tank. A heat exchanger within a heat pump and an electrical heating element in the air-distribution duct provide auxiliary energy for space heating. Similarly, an electrical heating element in the DHW tank provides auxiliary energy for water heating. The dwelling has been fully instrumented for performance evaluation since February 1977 and the data is integrated into the National Solar Data Network. Original cost estimates for provisioning and installation of the solar system are given.
