Energy consumption in the building sector accounts for about 35% of the South Korea’s total, and several policies and new technologies, products for carbon reduction are being introduced into the market. Slat controlled blinds are a type of technology that can actively respond to solar radiation blocking and lighting load reduction by controlling the angle of the slats installed on the windows of the building. In this study, a conventional-type blinds and slat controlled blinds were installed in two actual rooms, and valid data for 74 days including illumination control were operated to determine the effectiveness of performance by control. The indoor illuminance range of the conventional chamber was about 800~3,400 lux, but the slat controlled blinds chamber was formed at 500~1,400 lux, so the illuminance was stably changed, and as a result, it was confirmed that lighting energy was reduced by 81.5%. In addition, due to the effect of blocking solar radiation by slat control, the cooling energy consumption ratio was reduced by 24.3% during the same period.
