The purpose of this study is to reconsider the optimal lighting conditions in office buildings with respect to both the occupants' visual comfort and reduced energy use. This paper reports on how the lighting in office buildings in Japan changed after the events that followed the Great East Japan Earthquake in March 2011. For the first step, a survey of facility managers in office buildings was conducted nationwide. The survey focused on specific measures taken to reduce power consumption. Additionally, the occupants of each office building filled out a questionnaire about the lighting conditions in their working areas.The results showed that for about half or more buildings, saving measures for lighting and air-conditioning during the summer months were taken. With regards to lighting, the number of illuminated lamps was reduced (partial lighting) and ceiling luminaires were turned off automatically at a preset time in order to avoid forgetting to turn them off when unnecessary, such as lunch-time or at the end of working hours. It could be supposed that the desktop illuminance of the most of the office buildings shifted from 750-1000 lx to 300-500 lx due to electricity-saving measures.
