Abstract

The subject of this study is both determining the effect of location on earth and evaluating the effect of interior height to the position & dimension of light shelf used in natural lighting according to latitudes. After detecting the most suitable condition & dimension of light shelf for related latitude (0 degrees) & interior height (300 cm) in CIE* standard overcast sky, the effects of the light shelf is evaluated in CIE standard clear sky on different directions in this paper. Calculations will be done for every determined latitudes and for different office heights. This study aims to guide the right light shelf application for different latitudes on earth.
