Many studies have been done to study the advantage of using window shading devices as a means of controlling solar penetration into the building. Shading devices like blinds have been proved to have a significant effect on the heating and cooling load of the building. As it is easier and less costly to change blinds than changing the window system in a building, using blinds is a very effective way of improving building performance. Although many studies have been done, mostly the study focuses on window that is oriented towards the south. As it is obvious that in a real building windows can be facing any direction, in this study the effect of blinds on heating and cooling loads of a building has been done, when the design of blind is either horizontal or vertical, when it is placed either inside or outside and when the slat angle automatically changes based on either solar energy received on vertical wall or on horizontal surface (roof).
