A quick examination of the graphs for the calculated summer solar heat gains indicates that the highest rates of heat gain occur in the morning on the east orientation, and in the evening on the west orientation. These results support the hypothesis that the east and west orientations are less effective at excluding solar heat gain. To analyze the actual performance of the sunshade, it is important to compare the calculated gains with the shading device to an unshaded condition.

(Due to the symmetrical nature of the sun’s path, the east and west graphs are mirror images of each other. For clarity, only the east graph is presented here.)

These graphs indicate that the shading devices do have an effect on the pattern of daily solar gains for each orientation. The total gains on the south orientation are reduced by 25% from the unshaded condition. The total gains on the east and west orientation are reduced by 19% from the unshaded condition.
