Abstract
A heat-protective building cladding unit in which a frame carries two spaced apart transparent sheets. One or more movable members are arranged in the space between the transparent sheets for selective movement. The movable member may thus be moved selectively to permit or prevent solar radiation from passing between the two transparent sheets. The unit is mounted to enclose a selected area of a building wall onto which a selective absorbing layer has been applied. Heat is conducted from the selective layer to the building interior by heat pipes or a circulating fluid.
Claims13
A solar heated, thermally protective building cladding comprising:
- a building having an outer wall;
- a portion of an outer surface of the wall being covered by a selective absorbing layer;
- a plurality of heat pipes disposed in the wall in thermal communication with the selective absorbing layer, the pipes extending between the layer and the interior of the building;
- a frame carrying two spaced-apart transparent sheets having in the space therebetween one or more movable members arranged for movement to selectively permit or prevent solar radiation from passing between said sheets;
- and
- the frame being mounted upon the outer wall of the building enclosing the layer so as to form an air space between the layer and the innermost of said transparent sheets.
