| Outline of Final Research Achievements |
As energy saving measures for lighting, daylight utilization is expected to be highly effective, so it is required to be able to evaluate its effect appropriately. However, in the current calculation of annual daylight utilization effect, quality of indoor visual environment is insufficiently satisfied since glare from the window and spatial brightness by daylight utilization are not considered. Therefore, in this research, to development of annual calculation method of lighting energy saving effect which satisfied the quality of indoor visual environment of the daylight utilization using various shading devices, the subjective experiment with scale models and luminance analysis from annual daylight simulations were carried out. As a result, we showed the possibility of average luminance evaluation as index of spatial brightness, the possibility of existing index DGP as glare evaluation, and the calculation method for reduction effect of lighting consumption using them.
