| Abstract |
The purpose of this study is to evaluate the performance of visual environment for the installation of venetian blinds in residential space. RADIANCE program and various indicators are used to evaluate. Daylight factor and uniformity ratio derived from the BREEAM 2008 Multi-Residential tool are used to evaluate the indoor visual environment. Daylight glare was evaluated using the DGI and the DGP obtained from RADIANCE based evaluation tool “evalglare". Direct sunlight entering the room caused high daylight factor, low uniformity ratio and serious glare if there are no blinds. Venetian blinds of slat angle 0° are installed to control the direct sunlight and have less daylight, high uniformity ratio and suppress the glare. As a result, the case of installed venetian blinds at slat angle 0° has better indoor visual environment quality. And we have to control the blind slat angle to accept the reflective light to enhance the daylight factor. |
