This report provides detailed cost information for the solar space heating project at the Concord Light Plant in Concord, Massachusetts. The system utilizes 92 flat-plate air collectors, manufactured by Sunworks, having a net area of 1737 square feet. Solar energy is stored in a rock thermal storage bin of 1210 cubic feet which is located in a corner of the garage. Auxiliary energy is provided by electrical resistance heaters. Category costs are listed for the Town of Concord, General Contractor's materials, General Contractor's labor, and subcontract costs. The subcontract costs include materials, labor, overhead and profit costs for the steelwork in the collector support system, the flashing and caulking, the storage bin masonry, the electrical power wiring, the controls (system), and the roofing. A further breakdown of these costs was obtained for the steelwork subcontract. The construction cost for this project was $99,350 not including general contractor overhead and profit and general and administrative costs. (MOW)
