| Abstract |
It has recently been concerned about cooling loads due to solar radiation through windows for commercial buildings. External shadings can be used to effectively reduce the direct and global solar radiation on windows. This paper analyzed the direct and global solar radiation facing on a vertical window according to the projection factors(PF) of external horizontal and vertical shadings in its orientation for a clear day in Summer and then proposed Solar Heat Gain Coefficient(SHGC) multipliers for such external horizontal and vertical shadings. |
