Abstract

As a horizontal shading and reflecting device, the light-shelf is simple and powerful to improve the uniformity of daylighting illuminance. Also, it is possible to apply photovoltaic modules on the reflection plate of light-shelf. Therefore, the light-shelf is suitable for the comfort indoor visual environment and sustainable energy application. This study aims to evaluate the sunlighting and energy performance of the photovoltaic light-shelf for suggesting the efficient design. For the study, computer simulations are carried on Radiance, Solar-Pro and Energy-Plus programs. As, results, the sunlighting and unformity ratio are analyzed on the installation conditions. Also, the peek power was shown on 12:30. In this time, the volts are 12.6(V) to 13.9(V) and the currents are 1.3(A) to 2.4(A). the accumulate powers are 207.5(Kw) to 228.3(Kw) between 10:00(am) to 15:00(pm). And the immediate powers were 2.0(W) to 25.3(W).
