ABSTRACT
This chapter discusses the ways of preventing solar radiation entering the building, and methods for solar shading design. It focuses on the design of overhang geometry and louvre geometry and on testing designs using a dynamic simulation models (DSMs) sun-casting facility. In many instances it is not practical to design an overhang that is sufficiently long to shade the entire glazed surface. This is especially the case with full-height glazing. In such case a combination of an overhang and a louvre can provide a suitable solution. A common design problem occurs when the solar shading needs to be designed for a range of dates and times, so that direct solar gain is completely eliminated in that period. The chapter demonstrates this using the calculations for single solar altitude angles. It shows the case of a south-facing building.
