Most of domestic building generally don't have fixed shading devices considering of appearance and aesthetic issues. In this study is suggested that tilt window simultaneously has a role of shading and blocking solar radiation. The tilt window thermal performance is investigated by relationship between inclination and heatingㆍcooling road. As comparing vertical window with 5° and 7° of tilt window respectively, the heating load is increased by 3.6% and cooling load is reduced by 8.1% on 5° tilt window and the heating load is increased by 5.3% and cooling load is reduced by 11.5%on 5° tilt window. Especially, the total load of alternative tilt window is showed the reduction rate 2.6% and 3.6% compared of vertical window. Therefore, the tilt window is possible to role of shading of solar radiation and reduction of heating and cooling load.
