Outline of Final Research Achievements

Development and promulgation of energy-efficient design methods are important today because the energy efficiency of buildings is expected to be further improved. The visual comfort of the indoor environment must also be ensured at the same time. In this study, we developed a new evaluation method of space brightness as the index of visual comfort. For non-uniform light environment, average luminance distribution, weighted by its vertical and horizontal direction respectively, was proved to be efficient for estimating space brightness. To diffuse the evaluation method, we also developed a light distribution measurement tool that uses a commercially available digital single-lens reflex camera.
