Questions regarding changes described in scope
- Can you confirm my assumption that the VarFan variations were added only for TechIDs that appear as a base case?
- We should confirm that measure case techIDs are at least efficient as base case. If this cannot be confirm by reviewing inputs, then confirm via energy savings before we approve the pull request. If measure case is less efficient because base case has variable speed fan, consider upgrading measure case requirements to include variable speed fan as well.
General QC comments
- Remove unused file to avoid confusion: "commercial measures\SWHC046-04 Pkg HP AC Com\SWHC046-04 Pkg HP AC Com_Ex\cases\Htl&0&cDXHP&Ex&dxHP_equip__pkgEER.csv"
- "commercial measures\SWHC046-04 Pkg HP AC Com\SWHC046-04 Pkg HP AC Com_Htl_Ex\climates.csv" should point to T24_weight_averaged_ex_Htl.csv
- "commercial measures\SWHC046-04 Pkg HP AC Com\SWHC046-04 Pkg HP AC Com_Htl_Ex\cases\Htl&0&cDXHP&Ex&dxHP_equip__pkgEER.csv" needs sizing factor update
- for efficient editing we have a file "cDXHP.csv" to make edits to TechIDs and parameters. Please update this file first, then use 'create_hvac_copies.cmd' to automatically copy changes to other cohorts. If we need more than one variation of parameter input file, create a second template such as "cDXHP_without_VarFan.csv"There should not be a need to directly edit individual building types.

(Just to demonstrate, we can use a pull request review comment to highlight a change in the pull request conversation tab.) I see the updated sizing factors of 1.25 for heating and 1.15 for cooling in this cases file. No action required.

Confirming that I see the new techIDs with main_fan_speed = VARIABLE, and all other parameters matching the original, in the following cohorts:

Yes, VarFan variations were added only for TechIDs that are base cases in applicable building types:
I will confirm this via energy savings after running the simulations. All general QC comments have been addressed in the revision. |

See comments on two files. Also:
- Standard query files for the measure do not match the reference standard query (commercial measures\SWXX000-00 Measure Name\SWXX000-00 Measure Name_Ex\query.txt). This must match for compatibility with Com.py.
- commercial measures\SWHC046-04 Pkg HP AC Com\SWHC046-04 Pkg HP AC Com_Ex\query.txt
- commercial measures\SWHC046-04 Pkg HP AC Com\SWHC046-04 Pkg HP AC Com_Htl_Ex\query.txt
- This branch is one commit behind main branch, specifically the updated T24 new vintage codes files. This does not impact our simulations because we use existing vintage codes (T24_weight_averaged_ex.csv).

During data gathering of cooling capacity, I noticed that the query file in subfolder for vintage "Ex" has queries for heating capacity and air flow rate, but not for cooling capacity. Additional tasks:
- We should update the query files in subfolders to include cooling capacity and match between Ex and Htl_Ex
- Update the README.md to describe the process for coil list and cooling capacity calculation (similar to SWHC027)

Didn't see any activity to address my comments, so I addressed the outstanding comments about README and query files. |
