[Radiance-general] material properties of ancient window panes?

[Lars O. Grobe]

Hi John,

of course I watched your thread. In my model, the situation is a bit 
different. I don't care about exterior appearance, the windows are 
mainly light sources. However, as I am working on a model of a real 
building, I don't want to create a glass material just by guessing, and 
I am currently searching for e.g. measured data of glasses as used in 
that time. However... as almost all the light goes through these 
windows, the values of transmissivity and color will only change the 
numeric results, not the perceived appearance, right? So it is not that 
dangerous ;-)

Thank you + CU, Lars.
