[TRNSYS-users] external shading factor (multizone building)

[Joke De Beuckelaer]

Dear trnsys-users,

I've a question about how to calculate the external shading factor (multizone building). Is the following correct?

Suppose I've a window with a g-value of 0,37 and a g-value of 0,23 (external shading device + window).
The external shading factor becomes then: 1 - (gwindow+shadingdevice/ gwindow) = 1- (0.23/0.37) = 0.38


Kind regards,
