The units are used to collect and distribute solar energy into a building for heating purposes. The units consist of a multilayer construction, with a perforated sheet on the outer surface, a small void then a standard roof or wall system. The air within the void is heated and then distributed either naturally or with the assistance of a fan to the occupied space. These systems can be engineered to work in reverse and provide passive cooling and natural ventilation during warm periods.
