Calculate the following for a 3 ft 4 ft window with the label to the right. The summer design conditions for peak cooling load are 70 and 60% RH inside; 90 and 90% outside; and a peak direct solar radiation through the window of 1 80 2. Assume density = 0.075 3. Calculate the contribution to peak cooling load ( ) due to solar radiation. SHGC = 0.3
