shading coefficient

[10.5.8.3]

NOTE: This definition was changed in RP-16-17 Addendum 2. Deletions have a strike-through. New text is bold.

The ratio of solar heat gain through a glazing system under a specific set of conditions to the solar gain through a single layer (3.2 mm [1/8 inch]) of double-strength sheet glass under the same conditions.

This term has been deprecated. It has been replaced by solar heat gain coefficient, which is defined differently.
