Hi Chris, This thread is now in three locations. =) Yes, eplus_adduvf is merely to compute view factors; it's your job to take those and fold them into an EnergyPlus simulation or whatever. The issue with eplus_adduvf on Windows in the NREL installers is being looked at.

Hi ~~Chris,~~ Chris,

~~This thread is now in three locations. =) Yes, eplus_adduvf is merely to compute view factors; it's your job to take those~~

Regarding the Radiance executables and ~~fold them into an EnergyPlus simulation or whatever. The issue with eplus_adduvf on Windows in the~~ NREL installers issue: OK so the issue there is ~~being looked at.~~ that when you install OpenStudio, you get a copy of Radiance (installers and libraries) in [path_to_openstudio]\Radiance, but that installer does not modify your environment. We probably should, but we don't. The only piece of OpenStudio that uses Radiance is the Radiance Daylighting Measure, which sets up the proper environment variables from within the measure, so any Radiance bits called from the measure automagically work.

When you installed Radiance with the Radiance installer, that installer copied the very same executables to C:\Radiance (or wherever), AND set up PATH and RAYPATH to point to stuff in .\bin and .\lib respectively, and so it worked.

I'd recommend you install Radiance AND OpenStudio if you wish to use Radiance outside of the OpenStudio radiance measure context.

Regarding the eplus_adduvf operational issues, I'd suggest reaching out to Tianzhen Hong or @macumber here, as they worked on the development of this utility (four years ago).
