Air leakage type "unit total"

[joseph-robertson]

Pull Request Description

Update options_lookup and ResStockArguments to use unit total air leakage type instead of the current unit exterior only type w/ infiltration adjustment approach. Update BuildExistingModel to register adjusted total infiltration ACH50 value. Some related plots in: https://github.com/NREL/resstock/issues/728

Checklist

Not all may apply:

• [ ] ~Tests (and test files) have been updated~
• [x] Documentation has been updated
  • [x] If related to resstock-estimation, checklist includes data dictionary, source report, options saturation, options_lookup.
• [ ] Add to the changelog_dev.rst file
• [x] openstudio tasks.rb update_measures has been run
• [ ] No unexpected regression test changes on CI (checked comparison artifacts)

Next steps here are, in order:

• [ ] look at energy impacts (especially heating, cooling)
• [ ] compare our distributions to ResDB
• [x] replace the new cost multiplier approach with, e.g,, build_existing_model.air_infiltration_leakage_to_outside_xxx

Questions from meeting:

• How do we compare new ResStock distributions to what we have available on ResDB? Qualitative comparison?
• Convert from Normalized leakage (NL) to ACH50?
