Pull request overview

Pull Request Author

Add to this list or remove from it as applicable. This is a simple templated set of guidelines.

  • Title of PR should be user-synopsis style (clearly understandable in a standalone changelog context)
  • Label the PR with at least one of: Defect, Refactoring, NewFeature, Performance, and/or DoNoPublish
  • Pull requests that impact EnergyPlus code must also include unit tests to cover enhancement or defect repair
  • Author should provide a "walkthrough" of relevant code changes using a GitHub code review comment process
  • If any diffs are expected, author must demonstrate they are justified using plots and descriptions
  • If changes fix a defect, the fix should be demonstrated in plots and descriptions
  • If any defect files are updated to a more recent version, upload new versions here or on DevSupport
  • If IDD requires transition, transition source, rules, ExpandObjects, and IDFs must be updated, and add IDDChange label
  • If structural output changes, add to output rules file and add OutputChange label
  • If adding/removing any LaTeX docs or figures, update that document's CMakeLists file dependencies

Reviewer

This will not be exhaustively relevant to every PR.

  • Perform a Code Review on GitHub
  • If branch is behind develop, merge develop and build locally to check for side effects of the merge
  • If defect, verify by running develop branch and reproducing defect, then running PR and reproducing fix
  • If feature, test running new feature, try creative ways to break it
  • CI status: all green or justified
  • Check that performance is not impacted (CI Linux results include performance check)
  • Run Unit Test(s) locally
  • Check any new function arguments for performance impacts
  • Verify IDF naming conventions and styles, memos and notes and defaults
  • If new idf included, locally check the err file and other outputs

Naive try at fixing incorrect ExpandObjects warning

An extra field was added for Boiler:HotWater in #9925

```shell
$ /Applications/EnergyPlus-23-2-0/energyplus -D -d out -x /Applications/EnergyPlus-23-2-0/ExampleFiles/VAVSingleDuctConstFlowBoiler.idf

$ cat out/eplusout.experr
ExpandObjects: SEVERE: Too many fields were found for the object: Boiler:HotWater, Number expected=[17], Number found=[18]

I'm not sure whether I need to bump 17 to 18 here or not.

Also not sure if I need to do CALL AddToObjStr('Off Cycle Parasitic Fuel Load {W}','0') after https://github.com/NREL/EnergyPlus/blob/d07d7ad64207285b241ab79b67b66ed98e2db594/src/ExpandObjects/epfilter.f90#L26185

The End Use Subcategory isn't being explicitly written. But the Off Cycle does not have a default (though it defaults to 0.0 W in the C++ code... I wish the E+.idd did have an explicit \default 0.0
