Cost information is reported for the solar space heating and cooling project at the Mount Rushmore National Memorial Visitors' Center in Keystone, South Dakota. The retrofit solar energy system provides space heating for the entire visitors' center building and space cooling for the center observation room. The system utilizes six (6) banks of solar collectors with a net area of 1,725 square feet, mounted facing south on the east sloping roof in a sawtooth configuration. The collectors are double glazed and have copper absorber plates with a selective surface. Storage capacity is 3,000 gallons and is provided by a steel storage tank with fiberglass insulation. Solar space heating is accomplished by a solar coil in the air handling unit. Solar space cooling is provided by 3 three-ton absorption chillers and a coil in the air handling unit. The absorption chillers and storage tank are located in a solar mechanical room retrofit against the existing building. The construction costs of this solar space heating and cooling project are presented in this report. Category costs are listed by materials, labor, and subcontract cost. The installed cost of the system was $112,925, in 1977 dollars, not including general contractor and construction manager's overhead and profit, engineering fees, and general and administrative costs.
