Two independent systems are described - a direct gain passive solar space heating system and an active domestic hot water preheating system. Large south-facing windows and a clerestory skylight permit direct winter sun to enter the house. Solar energy thermal storage is provided by both water filled tubes and the concrete slab floor. Movable shutters and insulating curtains provide capability to reduce night heat losses. Summer overheat protection is provided by roof overhangs and by natural ventilation. A natural gas furnace and wood stove provide auxiliary space heat. The domestic hot water system has an array of liquid flat plate collector with a gross area of 53 square feet. Freeze protection is by drain-down. An 82-gallon solar preheat tank supplies water to a conventional 20-gallon domestic hot water tank. The collector, storage, heating load, and auxiliary loads subsystems and modes of operation are described for both systems. The house is instrumented for thermal performance evaluation. Original cost estimates for provisioning and installation of the solar system are given. (LEW)
