The various shading systems were set up in office buildings, and the height of them can be controlled by user or timer. But generally users don't control the shading systems. It can't take an advantage of daylight such as improvement of work efficiency, reduction of energy, and so on. This study conducted experiments on daylight distribution for different height of the roller shade and the venetian blind at Lawrence Berkeley National Laboratory. The roller shading system was installed at one room, the venetian blind was installed at the other room, and another room had not any shading system. And conditions of experiment was 0%, 40%, 60%, and 80% of a height of the window for height of the shading system. This study investigated an analysis and comparison to illumination and distribution of illumination at the indoor. And this study can be used for development of shading systems that take advantage of available daylight in space.
