Energy efficient window and skylight assemblies having self-contained ventilating systems. Two sheets of a transparent or translucent material are spaced apart in parallel relationship so as to form an air flow channel between the sheets. An adjustable shade is positioned in the air flow channel to regulate the amount of sunlight passing through the window and skylight assemblies. A fan in the top or bottom of the assembly causes air to be drawn into the assembly and passed through the air flow channel where it absorbs heat from the shade and sides of the assembly. This air is then directed into the building to provide heat or is vented to the outside to decrease the heat gain in the building.

A totally self-contained apparatus for use as a window or skylight assembly, and adapted for simultaneously controlling the amount of both sunlight and air admitted into a building, said apparatus comprising: a head member and a sill member; a first sheet of material through which sunlight can pass, said first sheet of material forming a major portion of the exterior surface of said apparatus and being mounted between said head and sill members; a second sheet of material through which sunlight can pass, said second sheet of material being spaced from said first sheet of material said second sheet of material forming a major portion of the interior surface of said window apparatus and being mounted between said head and sill members; first and second window jams positioned between said first and second sheets of material and extending from said head member to said sill member so as to form an essentially enclosed air flow channel; means, positioned in said air flow channel, for regulating the amount of sunlight passing through said apparatus; and ventilation means for directing air through said air flow channel, and comprising a motor-driven fan mounted within said air flow channel at one end thereof so as to circulate air through said air flow channel together with a plurality of apertures disposed in said head and sill members for placing said air flow channel in communication with the interior and exterior of said building and means for selectively opening and closing said apertures whereby air may selectively flow from one of (a) the outside to the inside of said building, (b) from the inside to the outside of said building, (c) from the inside of said building through said air flow channel and back to the inside of said building and (d) from the outside of said building through said air flow channel and back to the outside of said building.
