Abstract
A window/light shelf system enhances the daylight illumination with no glare. The air space between the double panes of the window is enlarged, and a mini blind-like, light reflective or absorbing, low transparent glass plates unit is integrated in the middle to control the daylighting and to eliminate the glare. With the light reflective unit open and closed per solar/climate conditions, the system serves as a window, a light shelf with no glare, a solar heating source in the winter, and a solar heat reflector in the summer.
Claims4
