Abstract

This study aims at making basic investigation for the future standard and regulation of building shape considering the quality of daylight around the building. Firstly, we simulated sky factor and relative illuminance in cloudy condition. Comparing their levels, it was found that sky factor could be representative index of the brightness in urban open space. Secondly, the relative solar energy in sunny condition and sunshine duration were calculated. Although the distribution of sunshine duration has wider spread toward east and west, these impacts spread to north intensively in the distribution of relative solar energy.
