2. 2 | Program Name or Ancillary Texteere.energy.gov Weatherization Program Notice 01-4: What states should be submitting in an audit package and why How Project Officers can verify the state is using the correct tool, priority list Triggers that the agencies may need audit training (and fast) Q/A Agenda

4. 4 | Program Name or Ancillary Texteere.energy.gov Using latest version of DOE-approved audit tool? Straightforward review of how the software has been used on the sample audits submitted –States list the measures typically enabled –States provide input data, assumptions, and audit results (recommended measures) for sample dwelling units –Model runs reviewed to ensure building characteristics are input properly climate data is appropriate measure costs and effective lives are accurate all appropriate measures are being considered Audit Review #1

5. 5 | Program Name or Ancillary Texteere.energy.gov Older version of DOE-approved audit tool or previously un-reviewed software? More detailed review: –Older models of approved software often over- or under-predict savings. Older models evaluated by Comparing its results to those predicted by the latest versions Checking to ensure the specific measures and interactions are calculated correctly –Unapproved software review still more complicated. Need to check: Appropriateness of heat transfer model How climate data is input and used Whether and how accurately building characteristics can be input Whether it can use energy bills and perform a utility bill analysis Whether measure interaction/cost effectiveness accurately considered Whether all appropriate measures are being considered. Audit Review #2

6. 6 | Program Name or Ancillary Texteere.energy.gov Additional reviews of older software – previously DOE-approved or unapproved software: Can it handle changes to related programs? Software might have been designed when LIHEAP paid for furnaces but no longer pays Software might have been designed to include non-WAP measures. Does this version exclude those? Audit Review #3

7. 7 | Program Name or Ancillary Texteere.energy.gov Energy audit procedures and field protocols must comply with regulations The following are evaluated along with the state audit procedures to verify compliance: Priority lists Measures installed General heat waste reduction lists Health and safety Energy audit procedures required for each building type Audit Procedures/Field Protocols #1

10. 10 | Program Name or Ancillary Texteere.energy.gov Priority List Evaluation #1 10 Number of Priority Lists Requested: Single-Family Housing Stock Number of Sample Audits Required to Document Each Priority List 140 220 312 49 57 65 74 8-103 11 or more2

11. 11 | Program Name or Ancillary Texteere.energy.gov Priority List Evaluation #2 Priority lists are reviewed to ensure they have been developed accurately and are consistent with regulations: Each list is compared to a list independently generated by the reviewers Comparison priority list uses State inputs, representative building shells and appropriate insulation levels, equipment efficiencies, climactic conditions and energy prices. Sensitivity analysis used to determine threshold R- values and equipment efficiencies. Mechanical measures reviewed to ensure adequate load sizing is performed and sizing includes compensating for measures higher on priority list 11

12. 12 | Program Name or Ancillary Texteere.energy.gov Priority List Evaluation #3 Measures that aren’t handled well by energy modeling tools? (solar water heaters, room air conditioners, refrigerators…) –Methodology is reviewed to ensure consistency with Weatherization methods and protocols. Reviewed for general heat waste reduction measures: low flow showerheads and faucets, caulking, door sweeps, pipe insulation, DHW insulation, filters –Contains all appropriate measures –Installation costs are reasonable Reviewed for H&S measures and testing –Contains all appropriate measures –Installation costs are reasonable –Good guidance for when measures are installed and for when 12
