The Cathedral Square solar site is a 10-story multi-unit apartment building in Vermont whose active solar energy system is designed to supply 51% of the hot water load. The system consists of 1798 square feet of flat plate collectors, a 2699 gallon water tank, and two auxiliary natural gas boilers that supply hot water to immersed heat exchanger in the auxiliary storage tank. The portion of the hot water load supplied was only 26%. The discrepancy is due to the fact that hot water consumption was less than expected. Performance data are tabulated for the system overall, the collector subsystem, and the domestic hot water subsystem for each month. Typical operation is illustrated by graphs of the temperatures at various parts of the system vs. time for a typical 24-hour period. The system operating sequence and solar energy utilization and losses are also graphed. (LEW)
