Scattergood School is located near Westbranch, IA, approximately 35 miles southeast of Cedar Rapids. Its solar-energy system is designed to supply approximately 75% of the average annual energy requirements for space heating the gymnasium and for heating hot-water for an adjacent locker room. Solar-heating is also available for a grain-drying silo retrofitted at the site. The site has an array of flat-plate collectors with a gross area of 2496 square feet that faces south at an angle of 50 degrees from the horizontal. Air is the medium used for transferring energy from the collector array to storage or directly to the gymnasium. Energy is stored in a bin containing 130,000 pounds of rocks and in two 120-gallon water preheating tanks. When solar energy is insufficient, propane gas heaters furnish auxiliary energy for space heating. Auxiliary heating for hot water is provided by standard electric immersion heaters in the 52-gallon domestic hot-water heater. The system, shown schematically, has five modes of solar operation, which are described. The Scattergood solar energy system satisfied 99% of the combined space heating and hot water demand of 3.8 million Btu. The operation of the solar energy system resulted in a savings of 6.1 million Btu of fossil energy at an expense of 0.49 million Btu of electrical energy. The solar energy system was operated in the summer mode during the month.
