| Abstract |
The shading system is a system that applies PV module to the shading device. Shading system can maximize benefits of daylight in the point of occupant comfort and energy savings. This study was to analyze characteristics of daylight distributions and evaluate the economic impact. In this study, shading system was simulated using Radiance of lighting simulation software for comparing daylight distributions. Economic evaluation using payback period was calculated by RETScreen of economic evaluation software. In calculating the payback period, the factors like initial cost, government support money, electricity charge rate, and others are included. The purpose of this study is to verify the applicability of shading system. |
