Abstract

Windows are the only part in buildings that can directly penetrate the solar radiation into the space and thus the shading devices are needed to control the solar penetration. In this study, optimized slat angle control strategies of venetian blinds are suggested. In the development process of the slat angle control strategy, annual cooling, heating, lighting energy and Daylight Glare Index performances are evaluated for each slat angle in the first hand, and then those comprehensive performances are categorized under different window solar radiation regions with the increment of 100 W/m2. After deriving the optimum slat angle showing the lowest total energy for cooling, heating and lighting in each solar radiation region, the slat angle showing the DGI greater than 22 is excluded. As a result, 29.2% of energy saving could be achieved and at the same time the chance of glare was only 0.1%.
