Abstract
As lighting energy consumption in buildings occupies high ratio, technical researches to solve it have been constantly carried out. However, basic studies on light environment performance evaluation is actually deficient and only at a level of a simple illumination monitoring. Thus, this study has suggest a light environment energy performance evaluation based on actual residence environments to allow setting lighting interoperation and user required illumination. Conclusions from the study are as follows: 1) As the performance evaluation suggested by this study has not only derived lighting energy usage as well as monitored simple indoor illumination distribution, it is quantitative and allows derivation of visual results. 2) The performance evaluation suggested by this study allows inputs of user required illumination through the performance evaluation server, which is able to support for performance evaluations for various works and users. 3) This study has verified validity of the performance evaluation method by analyzing results of lighting energy reduction by executing performance evaluation on changes of light shelf that is a natural lighting system through the suggested performance evaluation method. This study is significant from a viewpoint that it has suggested a quantitative performance evaluation method on the basis of actual residence environments. Those researches concerned on the energy performance evaluation should be constantly progressed from an aspect that they are another solution of the energy problems.
