A study is done on an Iraqi building to estimate and show how the use ofover hang reduces the cooling load. The study shows how the effectiveness ofover hang is affected by the orientation and the area (height) of the windows.This study shows that limit width of over hang on south window reduces thecooling load by (9%), and when using the over hang on the east or westwindow we need a large width over hang to reduce the cooling load by thesame percentage. Also this study shows that using over hang and increasingthe area of south windows allow us to receive a wide range of solar radiationin winter and use it in heating and lighting and the cooling load does notincrease by the same percentage when using west or east windows. The resultsshow that the using of over hang in Iraq is important especially for southwindows.
