Openstudio Envelope Section Error

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.
