Shading Coefficient VS G-Value
Shading Coefficient VS G-Value
(OP)
Hi,
I am not really sure whether this is the place to put this query into but here goes anyway.
I have a question regarding the difference between the shading coefficient and the G-value of the glass. I have looked into some documents and their interpretations vary quite significantly (in my view anyway). I basically want the basic definition of how you define each term.
Please shed some light on this matter. Thanks!

RE: Shading Coefficient VS G-Value
The Solar heat gain coefficient is the fraction of incident solar radiation that actually gets through a window as heat gain (transmitted radiation + absorbed and re-radiated energy). To convert a Shading Coefficent to SHGC, mutliply the SH by 1.15.
SHGC is the equivalent for the European G value. The only difference between the numbers is that SHGC uses an air mass of 1.5 and the g value uses an air mass of 1.0.
