Solar Shading Calculations and Design of Overhangs

Description:

Architectural projections, known as overhangs when they are horizontal or side fins when vertical, are commonly used in the building envelope to prevent or control the irradiation of a surface (typically a window). The shading device is usually designed to exclude solar radiation in summer when it contributes to a reduction in cooling loads and to admit it in winter when it contributes to a pleasant indoor environment and  a reduction of heating requirements.
