Performance



Without sunscreens, 100% of the sun’s thermal and visible energy may enter the building.


Sunscreens reduce the sun’s direct visible light while diffusing it, thus interior spaces are more evely day lighted and artificial lighting fixture usage may be reduced.


During summer months when the sun’s angle is steep, sunscreens reduce the sun’s thermal energy enterting the structure allowing to reduce the cooling costs.


During summer months when the sun’s angle is low, sunscreens allow the sun’s thermal energy into the structure allowing for a reduction in heating costs.

Shaded area as a percentage of area covered by sunshade (other than shading from window setback)
