[EnergyPlus_Support] Exterior Natural Vented Cavity

[<giorgia.ferlazzo@xxxxxxxxx>]

Hi there!

I'm studying an hospital facade with an exterior natural vented cavity.

I wrote the exterior wall construction (aluminium - air gap - insulation - brick - gypsum).

In BuildingSurface:Detailed I put:

Outside Boundary Condition: OtherSideConditionsModel

Outside Boundary Condition Object: the GapConvectionRadiation I created in SurfaceProperty:OtherSideConditionsModel

In SurfaceProperty:ExteriorNaturalVentedCavity I created the vented cavity.



Energy Plus terminates with this error:



   ** Severe  ** SurfaceProperty:ExteriorNaturalVentedCavity="FACCIATA VENTILATA", invalid .

   **   ~~~   ** ...because Plenum gap must be greater than Zero=[0.00].

   **  Fatal  ** GetSurfaceData: Errors discovered, program terminates.





Where can I modify this Plenum gap?



Thank you!



Giorgia
