1. Residential Weatherization and Ventilation Subcommittee: Infiltration Impact Research Plan Presentation to the Regional Technical Forum February 14, 2012

2. Residential WX Subcommittee Research Plan Review Process Committee meetings: – January 12 – January 26 Draft reviewed by evaluators Final reviewed by RTF Contractor and Staff

3. Research Plan Subcommittee Participants Warren Cook Crispin Wong Eli Caudill Adam Zielinski Jim Dolan David Hutchins Mark Johnson David Baylon Jim Maunder Subcommittee: Residential Weatherization and Ventilation Specifications 3 David Hales Mark Jerome Amanda Ayoud Bruce Manclark Ed Impala Mark Kendall Adam Hadley

4. Research Plan Context Air Sealing & Testing New section – Prescriptive and Whole House Defined accessible/non-accessible locations Provided Air Sealing Checklist with required sealing locations Specified testing protocol and CAZ test procedure Subcommittee: Residential Weatherization and Ventilation Specifications 4

5. RTF Research Plan Advise Subcommittee: Residential Weatherization and Ventilation Specifications 5 “The RTF advises that the region undertake an evaluation of the impact of the non-whole house air sealing weatherization measures through pre and post blower door tests with the RTF establishing a subcommittee to develop an evaluation design”

6. Purpose of Research Assess impact of prescriptive air sealing on blower door CFM 50 changes and ventilation Air sealing combined with: – Attic Insulation – Wall Insulation – Floor Insulation – Window Replacement Does NOT include: – Whole House Air Sealing – PTCS Duct Sealing

7. Research Plan Overview Purpose Data collection requirements Sampling Data Analysis and Reporting

8. Research Plan Analysis and Reporting Clean, well-defined data set Data quality and management Data analysis – Change in blower door CFM 50 test results – ASHRAE 62.2 ventilation change analysis Reporting to the RTF with – Data – Conclusions – Recommendations Subcommittee: Residential Weatherization and Ventilation Specifications 8

9. Utilities Expressing Interest EWEB – at least 20 sites, to RTF Spec Snohomish – at least 20 sites, to RTF Spec Callam – at least 20 sites, to RTF Spec Flathead – Like to participate, need more resources Tacoma - to a limited extent Energy Trust of Oregon – measure spec differs

10. Estimated Budget Minimum of 80 sites with data collected As many as six service territories interested Initial training and orientation expected $98,000 over all cost – $48,000 utility in-kind – $36,000 estimated orientation and training – $14,000 RTF Staff data analysis and reporting

11. RTF Proposed Motion: “I ____________move that the RTF adopt the Residential Weatherization Research Data Collection Plan for Determining the Impact of Prescriptive Air Sealing on Ventilation and Infiltration Resulting from the Implementation of the RTF Residential Weatherization Measure Specifications.”
