Interior wall as Air wall

edit

Choose the "Air Wall" construction for the two matched interior surfaces that you to change. Just as a note, the "Air Wall" construction is intended for modelers who plan to use the Radiance measure for daylighting. The "Air Wall" acts as a thermal zone boundary for EnergyPlus, but is ignored by Radiance.

I think this question is already answered here [https://unmethours.com/question/13094...] Did you take a look at this?

If you are looking at changing specific surfaces, you can change the Construction type to Air wall for the specific surface. In OS, you can access this from the Spaces tab > Surfaces > Construction. The easier way would be to change the construction name in the SketchUp OS model, by selecting the surface and manually assigning the Construction Name from the OpenStudio Inspector tool.
