The file is AirflowNetwork_Simple_House.idf which is an EnergyPlus 9.0.1 example file. Importing the idf into openstudio 2.8.0 and clicking the geometry tab displays some of the walls colored white instead of the usual tan. My OS is Windows 10.

There is a similar post here, but that post is from 2014 and has to do with modifying the geometry using sketchup, which I have not done.

Post Script
The white walls also stay opaque when turning off displaying the walls.

I figured it out. There is a case sensitive problem. The surfaces that are white were "WALL" and when I changed them to "Wall" it worked. This is also true for "FLOOR" and "Floor" if you look at the bottom of the house, but "ROOF" vs "Roof" and "CEILING" vs "Ceiling" didn't seem to matter.

@mldichter what version of OpenStudio are you using, what is the IDF file version (is it in sync with the OS version) and what platform are you on?

I can't reproduce this in mac with OpenStudio 2.8.0 and an EnergyPlus 9.0.1 file.

@David Goldwasser I upgraded from openstudio 2.7.0 to 2.8.0. I refetched the AirflowNetwork_Simple_House.idf energyplus 9.0.1 examples directory in case I modified at some point. The walls are still white. I also noticed that the white walls are still opaque when turning off the display walls check box.

@mldichter ah, I see I was in SketchUp but you are in OS app geometry tab. I can reproduce what you see there. Let me ping @macumber
