Abstract |
Recently, various daylighting systems have been developed and applied to buildings. However, existing daylighting systems are of no practical use due to a high initial cost and difficulties in maintenance. In addition, there is a main problem of securing sufficient additional space for collecting daylight and to be available in the overcast sky. A wall-integrated daylighting system, which is the subject of this study and doesn't need additional space for collecting daylight, is a very useful daylighting system, because it can substitute for a vertical wall of a building. The purpose of this study was to evaluate the daylighting performance of the wall-integrated daylighting system using two mock-up models. The performance of the general windows were compared with that of the wall-integrated daylighting system placed on the windows in terms of illuminance distribution on the work plane at the height of 75cm and luminance distribution on the south wall. Also. The purpose of this study is to find methods to minimize glare problems of a newly developed wall- integrated daylighting system. |
