[EnergyPlus_Support] reflective metal medallions on the facade

["marziasedino" <marziasedino@xxxxxxxx>]

Hi,

I am trying to calculate the glare index for a building which has got 
zig-zag curtain walls on all sides with reflective metal medallions.
The medallions are some sort of mirros on the outside of the facades 
and should reflect solar rays inside the building. So I am expecting 
big glare index inside.
my question is how to model reflective surface in E+.  

I tried to assign them as opaque surfaces but I couldn't really change 
their reflectivity. 
So i tried to simulate them as single windows with high reflectivity 
(0.9) and no trasmittance but still the glare index seems to low...

for the solar distribution I used both Fullexterior and 
Fullexteriorwithreflections.

Thanks a lot

Marzia
