The evaluation of distributed multiple-light arrangement in the daytime and nighttime using brightness image

摘要

As to the evaluation for combination of daylight and electric light, the the integration of the quality and the energy conservation is difficult. To evaluate lighted environmen by combination of daylight and electric light in the daytime, the reasonable method of analyzing brightness distribution that can be suitable fot the both daylighting and electric lighting based on the consideration of luminance distribution is needed. Therefore, in this study, we carried out the examination in the actual living-dining room from the morning till the evening (in the daytime and nighttime) , and analyzing the relationship between brightness image based on the luminance distribution as a new tool to evaluate lighting quality and energy conservation for one-day lighted situations of the distributed multiple light arrangement.
