This study is performed by method for the influx of natural light in underground space. to solve the several negative underground issues make the covered courtyard and high reflected wall toward the adjacent space. for illuminance level test of sunken garden space, the adjacent space size is 15M × 9M × 12M sunken Garden with space to install the ceiling on the size of the companion light performance analysis, and seasonal changes derived by the light of changes in performance. In addition, increase the distance of the wall and the adjacent space and estimate the average at true time P.M12. The resulting data indicate that the road was an average lux DESKTOP RADIANCE of the modeling and analysis was conducted.

The angles of blinds' slat would change the light environment, so it is necessary to figure out the exact role of the slat adjustment in terms of building energy. As the results of using Radiance and eQUEST program, the angles of blinds' slat for optimal light environment of inside are 30 to 40 degrees in March, 0 degrees in June and 20 degrees in December. In addition, seasonal energy loads of each angles that show the best light environment and the points of energy savings are -20 to 0 degrees in summer and 20 to 40 in winter. However, in the case of 20 to 40 degrees, the opportunity of good view may decrease, compared to when the angle is 0 degrees, and the effect of brightness which stems from slat's surfaces must be considered.

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.
