Abstract
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.
Claims19
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.
An apparatus for admitting sunlight and air into the interior of 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 being positioned between said members and forming a portion of the exterior surface of said apparatus;
- a second sheet of material through which sunlight can pass, said second sheet of material being positioned between said members and being spaced apart from and parallel to said first sheet so as to form an air space between said first and second sheets;
- a third sheet of material through which sunlight can pass, said third sheet of material being positioned between said members and being spaced apart from and parallel to said second sheet, said second sheet forming a portion of the interior surface of said apparatus;
- first and second window jams positioned between said first and third 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 light passing through said skylight;
- and
- ventilation means for directing air through said air flow channel, said ventilation means comprising a fan mounted at one end of said air flow channel adjacent the ends of said second and third sheets of material, and said ventilation means further comprising a first exhaust aperture connecting said air flow channel with the interior of said building and a second exhaust aperture connecting said air flow channel with the exterior of the building, and an inlet aperature connecting said air flow channel with the interior of the building together with 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.
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, and first and second window panes positioned between said head and sill members and spaced from one another and first and second window jams positioned between said window panes and extending from said head member to said sill member so as to form an essentially enclosed air flow channel between said window panes, and said window panes permitting entry of sunlight into said building:
- means, positioned in said air flow channel, for regulating the amount of sunlight admitted through said window panes;
- ventilation means for controlling the direction of air flow through said air flow channel comprising a plurality of aperatures 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;
- and
- forced air means, mounted in one of said head and sill members, for forcing said air flow through said air flow chamber whereby said forced air means cooperates with said ventilation means such that 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 chamber and back to the inside of said building and (d) from the outside of said building through said air chamber and back to the outside of said building.
