[EnergyPlus_Support] Glare index
Dear all,
I have a question about Glare Index.
First, I simulate an office with a single big window. The width and the height of the window is 1.8m, There are interior blinds for this window, the angle is 45 deg. Through simulation, I got a glare index in every hour.
Then, I divided the big window into 3 small windows (each is 1.8 (width)*0.6(height) by defining three objects (all of them are windows) in FenestrationSurface:Details. And each small window has the same binds angle and width as the above one.
The problem is when I ran the two simulation, I found the difference of glare index in these simulations (only the number of window is different) is nearly 10%. I am confused with this phenomenon.
Could you explain the reason? I thought the result should be quite close since the total area of the window is the same.
Thank you.
JH
