The Effect of Geometric Relation between the Window and the Sun on the Interior Illuminance Distributions using a Physical Scale Model

The existing building code regulates the minimum distance between buildings and the minimum required sunshine hours for winter solstice to ensure the right to light. Especially, the minimum sunshine hours have been guaranteed by the constitution after the right for the people to live in a healthy and comfortable environment was established. However, the existing regulation on the sunshine hours only considers the duration of sunshine hours, but ignores the minimum amount of sunlight. Therefore, the calculated sunshine hours are not coincident with the hours occupants actually feel. Therefore, the purpose of this study is to investigate the effect of solar incident angle on interior illuminance distribution, which will be used to propose a new code on the minimum sunshine hours and levels.
