Abstract: This paper proposes an optimal bland automatic control strategy, which is to set the optimal slat angle to block direct solar radiation and let maximum diffused daylight enter room for sunny day and set the optimal slat angle to let maximum daylight enter room for cloudy day. For the purpose of verifying the energy saving effect of the proposed control strategy, the outdoor and indoor solar radiation and illuminance at different blind slat angles are measured on a typical cloudy day and a sunny day. The measured data are used to calculate the cooling and lighting energy consumptions and compare with two common blind cases, which are fully opened bind (similar to no blind) case and fully closed blind case. The comparison results show that the optimal blind slat angle control can save cooling and lighting energy by about 60% comparing with the fully opened blind case, which is the largest energy consumption case. Comparing with the blind fully closed case, the optimal blind slat angle control can save cooling and lighting energy by about 50%.
