Abstract

The sky glow in Tokyo is considered to be caused not only by excessive upward light output from outdoor lighting. The purpose of this study is to determine the influence of the light from windows of office buildings on the sky glow in Tokyo. In order to identify the actual conditions of the spill light from office windows, field measurements were conducted in a park and, based on the results, the upward luminous flux from office windows was compared to that from out door lighting investigated by Illuminating Engineering Institute of Japan (IEIJ). Our research proves that it is necessary to consider not only the outdoor lighting but also the light spilled from the inside of buildings.
