PR Author

• Make sure the PR branch is up to date with main branch at the time of the PR submission
• Craft a succinct title that effectively encapsulates the essence of the pull request, providing a general overview of the proposed changes.
• Label the PR with at least one of the following: New Measure, Bug, or Feature.
• Provide a concise description of the measure, bug, or feature. Submit one PR per measure.
• For a new measure, attach a workbook named DEER_EnergyPlus_Modelkit_Measure_list_working.xlsx, containing only rows used for post-processing the measure.
• Add comments in the code when necessary to facilitate the review process.
• Add a comment before the added code, including the author's full name, company, and specifying if it's a bug fix, new measure, or feature.
• For a new feature or bug, demonstrate the impact on energy consumption for selected cases with justification using plots and descriptions.
• For a new measure, add a summary table showing total energy consumption per simulated case.

PR Reviewer

• Conduct a thorough code review.
• If the branch is behind the main, merge the branch locally to check for potential conflicts.
• If a bug, locally reproduce it and compare energy consumptions before and after.
• Explore creative ways to stress-test the code.
• Locally check the error file and other outputs.

@yagi-solaris, could you remove the rows in the DEER_EnergyPlus_Modelkit_Measure_list_SWHC044.xlsx file that are not related to this measure package?

[behzadsalimian]

@yagi-solaris, if you generate simdata file, locate the query file that you used along with the result2.py here residential measures
/SWHC044-08 Ductless HVAC Fuel Sub and update the README file and add any explanation needed for post-processing/running the simulation.

[behzadsalimian]

@yagi-solaris, can you add an explanation in the README file on when we should use this file and why this file has been created?

[yagi-solaris]

Added explanations to README file/addressed all comments.

[behzadsalimian]

@yagi-solaris, are you using this query file to generate the simdata file? I see you mentioned in the README file that you are using this command: cd C:/.../SWHC044-08 Ductless HVAC Fuel Sub Generate 'simdata.csv' using result2.py and query_default.txt. Is that correct?

[yagi-solaris]

Actually that was not the one I was using for result2.py, that was for result.py. I just corrected to the right query file and updated the README accordingly.

[yagi-solaris]

@behzadsalimian All done with discussed changes.

Yasemin added this bullet point for clarification: Revised AC baseline efficiency from 11.0 EER to 13.1 EER to align with the new federal minimum as of May 26, 2026. She modified the techID name in the case file to have the right EER and updated the cooling COP accordingly.

[behzadsalimian]

I verified that the measure list workbook is aligned with the TechIDs and measure offerings table in eTRM.
