외부 차양의 광 기능 성능에 관한 기초연구

In there last years, opening of the building had made a lot of constraints because of the structural problems. On the other hand, the developments of modern materials and structural engineering are free to make a plan of the building elevation and the influx of daylight can be done easily made thesedays. However, the amount of solar radiation entering into the building depend on the lighting conditions, external environment, location and orientation. The excessive daylight can rise the cooling load in the building and cause the discomfort visual environment for residents, so it is needed to find the alternatives. In this paper, the investigation was carried out via the use of Desktop Radiance for daylighting simulation and analyzed the typical Venetian blind, the shading device in the current research and the external shading device as known as a horizontal louver's performance with the illumination comparatively. the shading device in the current research is not simply a shading device of two-dimensional form, and three-dimensional form. besides, it has the merit of external shading devices.
