THE RELATIONSHIP BETWEEN THE SHAPE AND ALLOCATION OF BUILDINGS AND THE ILLUMINANCE ON THEIR EXTERIOR WALLS BY DAYLIGHTING

The purpose of this paper is to study the relationship between the shape and allocation of buildings and the performance of daylighting environment in urban building districts, to verify quantitatively the effect of the Height and Bulk Controls in the Zoning Code under the Building Standard Law. First, we simulated exterior wall illuminance on several urban building district models. Then, we got some technical findings about the relationship between the shape and allocation of buildings and exterior wall illuminance. Secondly, we analyzed the performance standard of exterior wall illuminance by daylighting to satisfy the needs of interior horizontal illuminance. Finally, we examined how the Height and Bulk Controls actually provide daylighting environment in urban building districts.
