Climate correction

[hagento]

Purpose of this PR

This PR applies climate correction factors to the final energy (FE) and useful energy (UE) demand calculations for buildings in the reportFE function. This is specifically necessary if cm_climateCorrection == on in REMIND (see PR ...).

Changes

• Reads pm_climateCorrection parameter from GDX file (exists if cm_climateCorrection == on, otherwise returns NULL)
• Applies climate correction to buildings FE demand by:
  • Removing offset quantities from raw CES inputs
  • Multiplying by climate correction factor
  • Re-adding offset quantities
• Uses climate-corrected FE values for calculating UE demand with efficiency factors

Impact

Buildings FE and UE reporting now properly reflects climate-adjusted energy demand, ensuring that reported values match the actual energy demand calculated in the model (vm_demFeSector) which includes climate corrections.

You can find a reporting comparing SSP2-NPi2025 with and without climate correction here: /p/tmp/hagento/dev/REMIND/climateCorrection/remind/compScen-climateCorrection-2026-06-09_13.41.26-H12.pdf

Checklist:

I checked the tests when running buildLibrary and made sure that my changes

• do not create new complaints about summation checks.
• do not create new complaints about missing variables that are expected in the piamInterfaces package. (If needed, adjust piamInterfaces mappings based on the README.md. In case of complaints unrelated to your changes that you are unable to fix, please open an issue in piamInterfaces.)
