Title: Performance evaluation of the Shenandoah Community Solar Recreational Center for the year 1980. Final report

Abstract

The Shenandoah Solar Recreational Center, when completed in early 1977, was the largest building to have most of its heating, air conditioning, and hot water needs met by solar energy. Principal components of the building solar energy system are a 1121 sq-m array of modularized flat plate collectors with 2300 sq-m of aluminum foreground reflectors integrated into a sawtooth wood truss roof, a 15.1 cu-m collector loop buffer tank, a 56.8 cu-m hot water storage tank, two 113.6 cu-m chilled water storage tanks, and a nominal 100 ton single stage absorption chiller. The system is interconnected by means of primary-secondary loops and was designed for simultaneous operation of all subsystems in either the heating or cooling modes. Control is by means of conventional HVAC pneumatic and electric control equipment. Transient thermal simulation studies were used to design the solar energy system. The collector array size was fixed so as to provide a significant fraction of the building annual thermal load, and the hot and chilled water storage volumes and other system functions were sized to maximize economic benefit. On this basis the predicted solar fractions were 95% space heating, 64% space cooling and 50% hot water. The building operation wasmore » monitored for a period on one year (February 1980 through February 1981) using a calculator-based data acquisition system with 80 sensors located throughout the building. This report presents an analysis of this data and an evaluation of the building performance over the year. The annual collector efficiency was found to be 19% and the overall annual solar fraction (combined thermal loads met from solar) was determined to be 39%. It is felt that this level of performance for a demonstration system is quite acceptable.« less
