The lightshelf system reduces intense illumination levels of indoor from direct sun light and reflect to lead a diffused light into indoor deeply. This study aims to design a curved-light shelf by the ray tracing method and evaluate the daylighting performance of window integrated with a curved-lightshelf by computer simulations. For this purpose, evaluation test model (1m*2m*1m) was designed for the experiments to validate the simulation model, and the curved-lightshelf was designed by the ray tracing method using Ecotect. The weather data for analyzing statistical data in each season was constructed. After the office model was designed using 3D simulation, the average indoor illuminance, luminance and distribution of illuminance were evaluated by simulation(Lighting Analysis of 3D Max Design) under four different cases (case 1; no lightshelf, case 2; Flat board, case 3; tilted at 30ºangle, case 4; the curved-lightshelf). As results, it turns out that case 1 showed higher average illuminance and was more uniformly distributed than case 3 and case 4, In addition average luminance of case 1 was also lower. indicating that the curved-lightshelf would reduce the possibility of the glare, while maintaining the sufficient daylight level. |
