Patent
CA 2327648
A multifunction window blind is disclosed which can be strategically used to improve the efficiency of solar energy collection by a window of a dwelling for heating purposes during winter, as well as to improve efficiency of rejection of the sun's incoming radiation for cooling purposes, during summer or in a hot climate. Heat transfer properties of the blind can be conveniently switched from energy collection mode to rejection mode, depending on the time of day or weather conditions. The same blind can be used for selectively enhancing retention or dissipation of heat during the night according to the exterior weather conditions. The disclosed structure includes a window blind with slats with different energy-absorption and energy- rejection properties of the surfaces on their opposite sides. The disclosed multifunction blinds can be used in place of conventional blinds with minimal or no modification to the existing windows.
