Description

In this study we investigated the lighting environment in train stations in the Metropolitan area after electricity saving measures have been implemented in the aftermath of the Great East Japan Earthquake. We found that even though Level A stations have higher recommended values for maintained illuminance in station concourses, illuminance of Level A and Level B stations had similar cumulative frequencies. During the interim period after electricity use restrictions were lifted, lighting rate was higher than during the summer period when the restrictions were being imposed, approaching nearly pre-earthquake conditions. In the future, the challenge is to propose methods for reducing lighting without reducing the quality of the lighting environment on the basis of the results of this study.
