| The calculated daily gain for each window bay could then be used to calculate the total daily solar heat gains for the entire building during summer. This was simply a matter of counting the number of bays for each orientation, multiplying this amount by their respective heat gains, and then adding the results together.
North = 3 South = 8 East = 2 West = 5 (see graph) Compared with the unshaded condition, the shading devices as a whole reduce solar heat gains by 18%. |
