SMUD JRT review

BKi will review all elements of the JRT to determine if revisions or clarifications are needed before the rebate is processed. Below is a list of the elements that will be reviewed on HPP project submissions:

  • Job Reporting Template review
    • Most recent version of JRT is used
    • All relevant fields of the Job Reporting Template are completed
      • All applicable checkboxes are selected on the Menu tab
      • All customer and assessment information reported on the JobInfo tab
      • Based on the upgrade measures selected, all relevant pre-retrofit, proposed, and post-retrofit conditions are reported on the JobInfo tab
    • The home qualifies for the upgrade measures selected, based on the pre-retrofit and proposed/post-retrofit conditions reported
    • The home’s proposed/post-retrofit meet these requirements:
      • Attic insulation R-38 or better
      • Air infiltration at or below 130% ASHRAE 62.2 mechanical ventilation standard
      • Duct leakage 8% or less
    • Upgrade achieves at least 10 savings units (as calculated on the Savings tab of the JRT)
  • Required photographs are provided
    • If existing attic insulation will be/was re-used, photographs documenting the condition of the old insulation
    • If HVAC or DHW equipment is replaced, photographs of data plates of that equipment
    • If deep buried ducts rebate is claimed, photographs of ducts according to the Deep Buried Ducts Protocol
  • The test-out PG&E Test Measurement Form has been completed correctly (if home has natural gas or propane service)
  • SMUD Rebate Application
    • ALL information on the SMUD Rebate Application (including accountholder name/address/account number, payee address, and rebate amount) must be correct and must match the information provided in the JRT
    • All required signatures from both customer and contractor have been acquired

Note for partially inaccessible ducts

If a significant portion of a home’s ducts are inaccessible, it may not be possible to achieve an overall duct leakage of 8% (6% for new ducts) if only the accessible ducts are sealed to 8%. In this instance, we can perform a weighted average of the test-in duct leakage and target duct leakage according to what percent of the ducts are accessible. This formula calculates the maximum allowable post-upgrade duct leakage for partially inaccessible duct systems:

[test-in leakage %] X [inaccessible duct %] + [target leakage] X [accessible duct %]

Example

Test-in duct leakage: 38%
Duct sealing measure leakage target: 8%
Accessible ducts: 90%
Inaccessible ducts: 10%

Maximum allowable total duct leakage =
0.38 X 0.10 + 0.08 X 0.90
0.038 + 0.072
0.11 (11%)
