Toplighting strategies provide daylight through rooftop apertures. These strategies can provide uniform daylight distribution to the entire top floor area if the entire top floor uses rooftop apertures distributed across the roof area. Large single level floor areas and the top floor of multi-story buildings can benefit from toplighting.
Sawtooth roofs employ a series of either vertical or sloped glasses, which are separated by sloped roof elements. Sawtooth roof can be used to uniformly illuminate a large floor area while minimizing impacts on building’s overall height. The orientation of the glazing can be selected so as to maximize daylight level while reducing direct solar radiation and heat gain.
