provides the expected solar heat gain for 1/8 in clear float glass at different latitudes, orientations, and times, which can be multiplied by the shading coefficient to correct for differences in radiation properties.The value of the shading coefficient ranges from 0 to 1. The lower the rating, the less solar heat is transmitted through the glass, and the greater its shading ability.

In addition to glass properties, shading devices integrated into the window assembly are also included in the SC calculation. Such devices can reduce the
