DOI:https://doi.org/10.2172/6660351· OSTI ID:6660351

The Kalwall Corporation is a commercial warehouse located in Manchester, New Hampshire. The direct-gain passive solar energy system was designed to supply approximately 50% of the annual space heating demand. The addition of roof insulation has resulted in system performance which exceeds these design projections. The structure is equipped with 1750 ft/sup 2/ of vertical south-facing glazing and 850 ft/sup 2/ of vertical east-facing glazing. The storage system consists of 817,000 pounds of dark-colored concrete in the eight-inch floor slab. Additional storage is in the materials stored in the warehouse. Auxiliary space heating is provided by two liquid-to-air heat exchangers supplied by the building boiler.
