Chapter 11 Fundamentals of Thermal Radiation 11-74 A building at 40º N latitude has double pane heat absorbing type windows that are equipped with light colored venetian blinds. The total solar heat gains of the building through the south windows at solar noon in April for the cases of with and without the blinds are to be determined. Assumptions The calculations are performed for an “average” day in April, and may vary from location to location. Properties The shading coefficient of a double pane heat absorbing type windows is SC = 0.58 (Table 11- 5). It is given to be SC = 0.30 in the case of blinds. The solar radiation incident at a South-facing surface at 12:00 noon in April is 559 W/m 2 (Table 11-4). Analysis The solar heat gain coefficient (SHGC) of the windows without the blinds is determined from
