[Radiance-general] Defining glazing properties

[Reinier Zeldenrust]

Hi Chris, Rob,

There is actually a way to extract BSDFs XMLs from Window, but it requires a bit of a roundabout way.

To extract the BSDF XML file from window:

1. Create the window system. Do initial calculation (F9). 

2. Enable Radiance calculations (under preferences). 

3. Run radiance calculations. This will not work for all materials, some don't have the right information to generate XMLs. If there is an issue saying Radiance is not installed, follow this solution: https://windows.lbl.gov/software/window/7/w7_faq.html#RadianceINI

4. Go to this location C:\Users\Public\LBNL\WINDOW7.3\BSDFs  (might be slightly different if you use a different version) to retrieve the XML BSDF file. 

5. Use in Radiance as a BSDF file. 

Hope this is helpful.

Welcome! As far as I know, you can't export to Radiance from Window, but you can from Optics. You end up with a simple "glass" definition, and a front and back material def using the BRTDfunc. Hopefully that's useful to you. (?)
