Outline of Final Research Achievements

This study was conducted in order to find adequate settings to control office lighting which is dimmed in accordance with the occupation of workers nearby. With several experiments, we studied how workers perceive the change of indoor lighting environment with several factors such as level of the illuminance before and after the change, speed of the change, position of the changing luminaire, and color of the light and interior. We also studied physiological effect of changing illuminance and the effect of changing illuminance with several settings on energy saving.
