According to the recent report, the lighting energy consumption of commercial buildings reaches to 30%¢¦40% of the total energy consumption. It is more than that of cooling & heating energy consumption and it is the major target of energy-saving strategy. It is obvious that they are interested in Daylighting device such as Light-shelf for the purpose of raising the lighting energy-saving efficiency. In most of highly developed countries, a thorough study on Light-shelf makes it possible to propose a practical plan ,while at home there leaves much to be desired to study a guiding principle of optimum plan in spite of its efficiency based on experiments using the scaled model and analysis of simulation.??Aiming at making an optimum plan of Light-shelf suitable for the domestic situation, this study is worked by experiments using light-shelf and analysis of variables??using illumination program. The result of this study is summarized as follows. 1. Concerning the presence of light-shelf itself, the ratio of??the maximum to the minimum inner illuminance and the proportion of inner daylight decrease 3.5 times as much as that, whereas a distribution of inner illuminance is uniformed |
