I'm having trouble deciphering my simulation error. It appears isolated to an envelope error but I am a rookie at this.

Running Openstudio 2.3.0

  Result: Success
  Initial Condition: Gathering data from EnergyPlus SQL file and OSM model.
  Final Condition: Generated report with 20 sections to ./report.html.
  Warn: Envelope section failed and was skipped because: Optional not initialized. Detail on error follows.

I removed all measures which included Openstudio Results and the Add Output Diagnostics measure. It seems to have eliminated the error, however, I would like to use the Openstudio Results measure. Any thoughts on how to correct this?

@Inigo Montoya, Are you running this in the OpenStudio Application, PAT, or through command line or ruby?

I'm a little confused. On the version of the measure on BCL line 1628 of the resource file is this.

if ext_const_base.include? surface.construction.get

The EnergyPlus simulation should have failed if a surface didn't have a construction, and the reporting measure should run when EnergyPlus fails. Do you have the EnergyPlus html output, and do you have any spaces in your model that are not assigned to a thermal zone? And do you have any issues with other sections of the measure?

This is in Openstudio. There is an attic space that is not assigned to a thermal zone, maybe that's the issue. No other issues I've found though though.

I do have the html output. I'm not sure the best way to upload the info. Link to it is here: https://drive.google.com/file/d/1Pgwx...

Having a space in the model that isn't assigned to a thermal zone would do this, at least if a surface in the space didn't have a construction assigned. It is an edge case I didn't consider because typically the simulation would fail because a surface in space "a" in the model would be matched to a surface in space "b" that isn't in the model.

We also have a check for the building area that OpenStudio reports vs. EnergyPlus that will throw a warning, which would also normally catch this, but my guess is the attic is set not to be included in the building area.

I can add a note to update the measure to add a warning, probably in the Building Summary table if there are space in the model that are not assigned to thermal zones.

You're correct. The attic is set to not be included in the building area. I will start looking into that space and see what I can find. Thanks.
