The purpose of this study is to determine the optimum slat angle of the venetian blind which was applied at an outer skin of a curtain-wall system. The evaluation of the blind slat angle was performed in terms of the comfortable visual environment and decreased energy consumption. The office building prototype was considered for the analysis and simulation variables include application of blind, blind slat angle and dimming control of lighting. The annual energy consumption and incidence rate of discomfort glare were analyzed using EnergyPlus which is developed by the U. S. Department of Energy for the detailed building energy simulation. As a result, it turns out that when the blind (reflectance: 0.5) was installed, the annual energy consumption was greater than the base model. However, when the dimming control was applied, the maximum energy saving of 16.3% could be achieved at a slat angle of 0°. In addition, in case of the base model, the incidence rate of discomfort glare was 84%, while the case of the blind with the slat angle of 0° showed that the incidence rate of discomfort glare was 42.4%. Consequently, the results showed that the slat angle of 55° with dimming control was the optimum strategy for the comfortable visual environment and decreased energy consumption. |
