Defining glazing properties

Full disclosure - I am a newbie working through Rendering With Radiance and having a lot of fun. One question, is it possible to import or define the spectral characteristics of glazing systems in Radiance? For example, if I define a glazing system with Window 7, is there a way to enter those properties in Radiance for daylighting analysis?

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. (?)

Yes, that's great. My intro to Radiance was SPOTPro. I am now pursuing the csh shell approach.

I am familiar with Optics although I haven't used it in quite a few years.

I will report back.

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.

Cool, thanks for this summary, Reinier!
