SWHC005 Update following 2025 Title 24 codes file update

Pull Request (PR) Description

This pull request includes commits from and supersedes #72. Cumulative setup description:

• Measure setup for water cooled chillers in measure folder "commercial measures/SWHC020-05 Air Cooled Chiller"

Initial work (2024)

• Added water-cooled chiller performance curve definitions from Energy Solutions research and from EnergyPlus library file "chiller.idf".
• Added new parameter (chw_)wc_option to allow switching water-cooled chiller object type from Chiller:Electric:ReformulatedEIR to Chiller:Electric:EIR (in the chw.pxt template).
• Added new parameter (chw_)chiller_eir_fplr_type to support Lift type EIR curve as a function of PLR. Initially, we do not propose linking this to chiller_model (in chw.pxt).
• Introduced query file for collecting data for IPLV and chiller cooling capacity (query_wcc.txt).
• Measure setup for chillers reflects distinct offerings varying by chiller type, capacity, and tier since code requirements vary by chiller type and capacity.

Revisions (2025)

• Apply 2025 Title 24 updates to SWHC005.
• Tech runs for screw type chiller are defined but skipped for simulation.

Performance curves proposed to add to chw.pxt

Measure case performance curve candidates

• "Model 9 WC Chiller" (ReformEIRChiller type, EIR_fPLR curve type = Lift, curves provided by email Energy Solutions)
• "Model 7 WC Chiller" (ReformEIRChiller type, EIR_fPLR curve type = Lift, curves provided by email Energy Solutions)
  Base case performance curve candidates from EnergyPlus dataset chillers.idf
• Added "WC Cent Carrier 19XR 1234kW/5.39COP/VSD" (ElectricEIRChiller type)
• Added "WC Trane RTHB 1051kW/5.05COP/Valve" (ElectricEIRChiller type)
• Added "ReformEIRChiller WC Cent Carrier 19XR 1234kW/5.39COP/VSD" (ReformEIRChiller type)
• Added "ReformEIRChiller Screw WC Carrier 23XL 1062kW/5.50COP/Valve" (ReformEIRChiller type)

PR Review Checklist

PR Owner

• Label the PR with at least one of the following: New Measure, Bug, or Feature.
  • New Measure
• Assign a reviewer.

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.
• 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.
  • See eTRM
• For a new measure, add a summary table showing total energy consumption per simulated case.
  • See eTRM

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.
