Information on how much daylighting can reduce the electricity used in illumination is useful for designing green buildings. In this paper, concepts of “daylight area” are reviewed considering several guidelines. Daylighting potential in an area was investigated with a metric known as Daylight Autonomy using a dynamic daylighting simulation software. In the investigated cases, the direction of windows had little influence. In addition, although a simple analysis using daylight factor and diffuse horizontal illuminance is not sufficient to simulate sequential daylighting, it may be useful to predict Daylight Autonomy under the climatic conditions in Japan.
