- Heat Gain The following graphs show the typical heat gain, in BTU per hour per square foot, for windows one with plain glass and one that is triple glazed in Pittsburgh in June, one facing east and one facing south. The horizontal axis gives the time of the day. Estimate the total heat gain per square foot by summing the areas of rectangle. Use rectangles with widths of 2hours, and let the function value at the midpoint of the subinterval give the height of rectangle. Source: Sustainable by Design. a.
