WEATHERIZATION ASSISTANCE PROGRAM

1. WEATHERIZATION ASSISTANCE PROGRAM Glen Salas SMS gsalas@sms-results.com (301) 628-2033 Audits 201

2. Agenda • 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

3. Required Submittals 7. Measures installed 8. Priority lists 9. General heat waste reduction lists 10. Health and safety 11. Energy audit procedures required for each building type served 1. Energy estimating methodology 2. Measure interaction 3. Cost-effectiveness requirements 4. Measures considered 5. Sample audits 6. Audit procedures and field protocols

4. Audit Review #1 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

5. Audit Review #2 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.

6. Audit Review #3 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?

7. Audit Procedures/Field Protocols #1 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

8. Types of Priority Lists #1

9. Types of Priority Lists #2

10. Priority List Evaluation #1

11. 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

12. 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

18. Comparing Audit/Actual

19. Agency Needs Training! • The auditor can’t explain how the audit operates • Onsite observed installed measures frequently don’t match audit recommendations • Audit reports are obviously being filled in after the work is done • Clients tell you the auditor promised certain measures at initial audit assessment • When agency repeatedly installs low priority measures over higher priority ones – installing numerous windows and doors but never air sealing attics – and audit reports back doing so.  (suspect “gaming”) • NEAT: When you find critical or high priority measures “turned off”

26. Health and Safety Related Subspace Repairs Were health and safety repairs performed and documented? Photo Source: U.S. Department of Energy Crimped flex vent at the back of a dryer should be replaced with smooth metal vent and terminated outdoors Photo courtesy of U.S. Department of Energy

27. Sunscreens/Films Recommended for: • South-, west- and east-facing windows not shaded during summer months • When solar gain overheats room causing increase in A/C use Photo Source: U.S. Department of Energy This window is already shaded by a nearby tree. Evaluate cooling-season exposure to determine cost effectiveness of window shades or solar films.
