I am modeling a warehouse that is a single space but needs to be broken into multiple thermal zones. I have created the space and zones and have downloaded the Air Wall Zone Mixing measure from the BCL. When I go to apply the measure from the apply measure now window, the modeler description and input fields are empty. Is this an issue with the new version of OpenStudio? I am using OpenStudio Application version 1.1.0 and openstudio SDK version 3.1.0. The measure says its compatible with OS versions 2.8 and later.

Sorry you are having problems with the copy on BCL, I did just test the GitHub copy and that appears to work and can be found here https://github.com/NREL/openstudio-common-measures-gem/tree/develop/lib/measures/air_wall_zone_mixing

Here is screenshot image description

You could also consider the new Air Boundary Construction object in OpenStudio, which supports new EnergyPlus air wall capability. That is shown below. image description

I did just get it updated on BCL so it should match GitHub. So you can try to update your local BCL copy instead of using GitHub.

Thanks! I am able to apply the measure now, however after applying the measure and running the simulation I get severe errors saying that "'Surface xxx' uses Construction:AirBoundary in a non-interzone surface" for each surface that separates my zones. Also, where can I find more information on the air boundary construction object? I do not see information in the Input output reference.

Thanks for your assistance.
