Abstract

See full text

Optical elements and systems are disclosed that can be incorporated into buildings to prevent beam sunlight from entering through apertures of the building while allowing diffuse skylight to enter the building through the apertures. The optical system comprises optical elements configured to admit diffuse skylight through an aperture in the building envelope, while reflecting away the beam sunlight incident on the aperture in the building envelope. The apertures can be, for example, windows in walls or skylights in roofs of the building envelope. The optical system works for both windows in the walls and skylights in the roof, with somewhat different configurations for those two parts of the building envelope.
