The heat gain through the glass window with blind in the shortwave part of radiation (solar heat gain coefficient in the shortwave part of radiation (ShW SHGC)) is analyzed.
It is found that the ShW SHGC is mainly affected by the slat properties, slat angle and solar profile angle.
The glass window using blind with a lower value of slat reflectance, will have a smaller value of ShW SHGC.
The slat distance also affects the ShW SHGC.
The glass window using blind with a lower value of slat distance has a lower value of ShW SHGC.
The effect of the slat curvature on the ShW SHGC is small when compared to the effect of other parameters.
The effects of the investigated parameters on the ShW SHGC for diffuse radiation are similar to the effects on the ShW SHGC for direct radiation.
