Overhang and fins are traditional and popular shading designs in the world to block direct solar radiation through windows. Since external shadings block out unwanted radiant heat gain, this reduces the cooling load of the air-conditioning system. Use of overhang/fins alter the effective SHGC of window and this is known as called equivalent SHGC. An online tool has been developed to calculate equivalent SHGC for given inputs related to shading devices and glass parameters.
