ABSTRACT:
A comprehensive method, and apparatus implementing the method, for providing beam daylighting to a room by one or more reflectors positioned in a window wall of the room. The method involves a mathematical analysis of solar and reflected beam vectors and in determining the optimum orientation of a vector normal to the reflecting surface to provide the best combination of depth of penetration of light into the room while keeping glare to an acceptable level. Arrays of both stationary and moveable reflectors implementing the method are disclosed. In the case of stationary arrays, preferably two are provided in each installation which respectively optimize performance of reflections during periods when the solar beam vector is on the easterly ana westerly sides of a line perpendicular to the window wall. All reflectors are positioned with the vector normal thereto oriented with three nonzero components in a rectangular coordinate system related to the plane of the window wall and taking into consideration the site latitude.
