Abstract
Windows are account for the majority of the heat gain in buildings, and to reduce the heat gain, exterior shutters are commonly installed in residential buildings in hot climates. The shutter is typically incompletely close during the daytime to have indoor natural lighting, which potentially reducing the thermal effectiveness of the shutter. Since there is temperature difference between the window glass and shutter, natural convection flow in induced in the space between the window and shutter. Experimental measurements are employed to study the effect of the shatter on the heat gain through the window during the month of June. The results indicate that when the shutter is incompletely closed, the heat gain through window can be increased by 44.5%, depending on the shutter opening distance.
