Hi everyone,

I'd like to apply the outside boundary condition "GroundSlabPreprocessorAverage" to a floor surface in OpenStudio (OS 1.10.5 and E+ V8.5). But the simulation fails, and I get this message in eplusout.err :

* Severe * BuildingSurface:Detailed="SURFACE 1", invalid Outside Boundary Condition="GROUNDSLABPREPROCESSORAVERAGE". * ~~~ * The ExpandObjects program has not been run or is not in your EnergyPlus.exe folder.

I tried to scan for tools but it didn't solve the problem. Any idea ?

Thanks a lot, Tristan
