SWWH014-09: Workaround for NR and NC permutations sharing the same load shape

As a Measure Developer, I want a supported way to use the same modeled load shape data across Existing and New vintages, so that CET can successfully run impact profiles where the modeled energy results are intentionally the same across vintages.

Sophiya reported an issue with SWWH014-09 Heat Pump Water Heater, Residential. The CET run failed because an Impact Profile ID was not available for the New vintage for some measures.

Following further clarification, the issue is not that the base and measure case use the same load shape.

For SWWH014-09:

• Normal Replacement (NR / Existing) and New Construction (NC / New) have the same modeled savings and load shapes.

• eTRM permutations include both Existing (Ex) and New (New) vintages, resulting in expected Load Shape / Impact Profile IDs for both.

• The underlying modeling was only run for the NR / Existing building configuration. The NR energy results were then also used for the NC permutations in eTRM because the water heating measure was not expected to be affected by differences between the building vintages.

• As a result, the generated 8760 files only contain Load Shape IDs associated with the Existing (Ex) vintage.

• The corresponding New (New) vintage Load Shape IDs are therefore not included in the uploaded load shape files.

• CET fails when processing the NC permutations because the expected New vintage Impact Profiles cannot be generated from the uploaded data.

Note we have a ticket in the backlog to Allow measure packages to share load shapes
