I downloaded the "Add Output Diagnostics" as a measure off of the BCL while in OpenStudio then dragged the measure file to the "Energy Plus Measures". I then ran the model and did not receive any additional output information in the eplusout.err file.

After downloading the "add Output DIagnostics" I am still getting this output in my eplusout.err file:

** Warning ** GetSurfaceData: There are 4 coincident/collinear vertices; These have been deleted unless the deletion would bring the number of surface sides < 3.
   **   ~~~   ** **For explicit details on each problem surface, use Output:Diagnostics,DisplayExtraWarnings;**
   ** Severe  ** GetSurfaceData: There are 1 degenerate surfaces; Degenerate surfaces are those with number of sides < 3.
   **   ~~~   ** These surfaces should be deleted.
   **   ~~~   ** For explicit details on each problem surface, use Output:Diagnostics,DisplayExtraWarnings;
   **  Fatal  ** GetSurfaceData: Errors discovered, program terminates.

@Valentina Rappa could you post a link to your model?

Do you see an uploaded file now? This is my first time using Unmet Hours. I selected the attach button to attach the file to my post and it seems like the file should now be attached but I don't see it attached on my end. I checked my rights and it says that I have the right to upload files now so I am not sure why it would not upload.

@Valentina Rappa You cant do that. Upload is for short text or pictures and I think that you can start using it only with 20 points of Karma. Use one of the cloud storage service such as Dropbox and post a link.

I see, thank you. I have just added the link at the bottom of my post.

You are correct that after using the measure it is not more obvious what the severe warnings are about. (It might be a bug). Anyway if you will not use the measure the error log is much clearer:

 ** Warning ** GetSurfaceData: Very small surface area[1.26107E-004], Surface=SURFACE 149
   ** Warning ** GetSurfaceData: WindowProperty:ShadingControl: "SHADING CONTROL 1" is not referenced by any window.
   ** Warning ** CalcSurfaceCentroid: 249 Surfaces have the Z coordinate < 0.
   **   ~~~   ** ...in any calculations, Wind Speed will be 0.0 for these surfaces.
   **   ~~~   ** ...in any calculations, Outside temperatures will be the outside temperature + 9.750E-003 for these surfaces.
   **   ~~~   ** ...that is, these surfaces will have conditions as though at ground level.
   ** Warning ** GetSurfaceData: There are 4 coincident/collinear vertices; These have been deleted unless the deletion would bring the number of surface sides < 3.
   **   ~~~   ** For explicit details on each problem surface, use Output:Diagnostics,DisplayExtraWarnings;
   ** Severe  ** GetSurfaceData: There are 1 degenerate surfaces; Degenerate surfaces are those with number of sides < 3.
   **   ~~~   ** These surfaces should be deleted.
   **   ~~~   ** For explicit details on each problem surface, use Output:Diagnostics,DisplayExtraWarnings;
   **  Fatal  ** GetSurfaceData: Errors discovered, program terminates.

You can see that the problematic surface is Surface 149 (to small) actually it is only a line or so, that is why E+ says: image description There are 4 coincident/collinear vertices and When it tries to autocorrect it it creates the warning you asked about ( degenerate surfaces). I could spot it by using Sketchup OS plugin and searching for that surface:

Since I peeked into your model: Most of the severe warnings are about surfaces with constructions of a window. If you intended to simulate a glass faced I think you should first create a wall and then create subsurface over the most but not all of it ( again OS shortcome) for the windows.

Also I could see that in many cases you specified wrong type surface Roof/Ceiling instead of floor and vice versa. Again this is easily spotted in Sketchup:

Thank you very much Avi! So as of now it looks like surface 149 is the only one that is a degenerate, correct?

Best, Valentina

@Valentina Rappa that is correct

Thank you. I will go in and edit that surface and see if my model is able to run.
