i modeled my project in Revit and export to Openstudio and Energy plus , but while simulation this is severe error Severe * SetupEnclosuresAndAirBoundaries: 8 surfaces use Construction: AirBoundary in non-interzone surfaces. * ~~~ ** For explicit details on each use, use Output:Diagnostics,DisplayExtraWarnings;

I don't know to fix it revit about AirBoundary. thanks
