HVAC Replacement Engine Bug #87

Open fishbaugher opened 3 months ago

fishbaugher commented 3 months ago

I was looking into #86 to see why the HVAC replacement had such a low SIR and discovered an engine error in HVAC replacement calculations. In audit 1125, both a furnace and AC Window replacement are called for:

VERY unlikely that the AC replacement has exactly the heating savings as the furnace replacement...

thank you for noting. This looks like the first pass (non-interacted), and no heating savings is shown for the AC in the report.

I question the "Priority CRITICAL (If not fixed, WAweb in not usable!)" label, as there is as yet no indication that it has any impact on the final measure selection and economics.

Sorry, I did not show the final pass impact on SIR which is first order. The Window AC replacement has SIR 2.59 which is off by a large factor due to the large heating energy dollar savings.

I'm not seeing the "off by a large factor due to the large heating energy dollar savings". The report energy savings, dollar savings, and SIR for Window AC Replacement in Audit #1125 appear to be appropriate.

No heating savings is shown, nor appears to be included in the economic calculations.

I continue to fail to see the "Priority Critical" label as appropriate.

Please provide one (or more) example(s) where this causes an actual miscalculation in energy savings, dollar savings, and/or measure SIR as reported on the Recommended Measures Report.

If none can be provided, then it does not appear to impact measure selection nor economic calculations and the "Priority Critical" label is inappropriate and should be removed.
