Solar heat gain thru glass,Btu/(hr)-(sq ft)

Case 1; With Storage factor

Multiplying of "Peak solar heat gain thru ordinary glass" (at the selected month , location ,exposure) and " Storage load factors of solar heat gain".

( Table 6, 9 for Peak solar heat gain thru ordinary glass and Table 7,8,9,10 or 11 ,Page 30-34 for Storage load factors of solar heat gain thruglass) :

Example : The peak solar heat gain for a west exposure

in July at 40 north Latitude = 164 Btu/hr-sqft (Tbl.6) and the

Storage load factor with internal shade = 0.66 for a west exposure at 4 pm ,the weight ~ 100 lb/sq ft. So, the

Solar heat gain thru glass for a west = 164x0.66 =

108.24 Btu/hr

Case 2 ;Without Storage factor
