At a Glance
Weatherization involves a number of individual measures aimed at improving the insulation levels, and efficiency of a building, in this case a single-family home. For this measure it refers to installation of envelope improvements that include attic insulation, wall insulation, floor insulation, prime window replacement, window efficiency upgrades, and infiltration reduction.

Decision details
Approved Measure Changes
Decision DetailsAdopt the updates to the Residential Single Family and Manufactured Homes Weatherization UES Measures as presented and:
- Add Gas Furnace measure identifiers
- Adjust assumed AFUEs based on data collected in both RBSAI and RBSAII
- For the Gas Furnace measure identifiers, set the Categories to
- Proven for all SF measure applications, except Windows
- Planning for all SF Window measure applications
- Small Saver for all MH measure applications
- Change the Statuses to Active
- Adopt the Research Strategy as presented
- Leave the Sunset Dates unchanged.
Approved Measure Changes
Decision DetailsAdopt the updates to the Residential SF Weatherization Measures as presented and:
- Set the Category to Planning
- Set the Status to Under Review
- Set the Sunset Date to Oct. 31, 2022
- Review, and if needed update, ASHP sizing assumptions based on BPA CC&S data set
Extend Sunset Dates
Decision DetailsExtend the sunset date for the Floating Head Pressure Controls UES to September 2019
Extend the sunset date for the following measures to November 2019:
- ASPH upgrades SF
- CC&S SF
- ASHP Upgrades and Conversions MH
- CC&S MH
- MH Weatherization (Heat Pumps)
- DHP in Zonal Electric Resistance Homes SF
- DHP in Zonal Electric Resistance Homes MH
- SF Weatherization
Approve measure update
Decision DetailsApprove the measure specification, savings*, cost, and measure life for the Residential Low-e Storm Windows UES measures (except Wood frame, Double-Pane and NFRC-rated 0.30 u-factor applications) as presented and: Set the status to Active; Set the category to Proven; Set the sunset date to September 2019. * Savings methodology and inputs are being approved here. Savings values will change after removing the cooling savings, adding infiltration reduction, and making the 93/96 adjustment as discussed today; staff will bring back the final results in a Management Update presentation.
Approve measure update
Decision DetailsAdopt the delivery verification guidance, and related specification changes, as presented and with a 30 day review period, for the following measures:Residential Weatherization (SF and MH); Residential Performance Based Duct Sealing (SF and MH); Residential Commissioning Controls and Sizing (SF and MH).
Approve measure update
Decision DetailsFor Residential Weatherization (for houses with heat pumps) UES measures; Adopt the Research Strategy that was previously adopted for CC&S UES measure, change the category from ‘Proven’ to ‘Planning’, keep the status as ‘Active’ and keep the sunset date at September 2019.
Approve measure update
Decision DetailsApprove a measure life of 45 years for the Existing Single Family Window UES measures.
Allocate resources to measure development
Decision DetailsAllocate RTF Staff resources towards developing:A Residential Low E Storm Windows UES measure, and A Residential Duct Insulation UES mesure, and A Residential Prescriptive Air Sealing UES measure, and A Non-Residential Lighting Code Compliant Standard Protocol, and A Next Step Homes measure.
Approve Measure Update
Decision DetailsApprove a measure life of 15 years for the Existing Single Family Infiltration Reduction (Air Sealing) UES measures.
Sunset date extension
Decision DetailsSet the sunset date for SF Weatherization UES measures to September 30, 2019.
Approve measure update
Decision DetailsAdopt the updated savings and costs for Single Family Weatherization UES measures as proposed and set measure status and category as follows: Attic Insulation:Status = Active, Category = Proven; Wall Insulation: Status = Active, Category = Proven; Floor Insulation: Status = Active, Category = Proven; Window Retrofit: Status = Active, Category = ProvenWindow Upgrades: Status = Active, Category = Proven; Infiltration Reduction:Status = Active, Category = Proven
Direction for further analysis
Decision DetailsUse Option 3 in estimating the savings for residential heating system and weatherization measures, and that the RTF delegate a decision on the definition of the “full measure package” to a subcommittee.
Direction for SEEM calibration
Decision DetailsApprove SEEM 94 as calibrated for single family houses (using model A in today's presentation). The validity of the calibration should be reviewed by May 31, 2016 with any new data that become available.
Approve measure update with direction for subcommittee
Decision DetailsApprove SF and MH Residential Weatherization Infiltration Reduction. Change measure status to Active. (Infiltration measures to "Under Review" status).
RTF staff to work with subcommittee to come up with a proposal to estimate savings and costs. Infiltration Reduction measures do not account for the increased mechanical ventilation requirements required by the measure. Savings are too high, costs are too low.
Direction for further analysis
Decision DetailsThe RTF adopted 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.”
Approve measure update with direction for subcommittee
Decision DetailsThe RTF approved the Residential Weatherization Inspector Examination and method developed by the Residential Weatherization Specification Subcommittee.
Res WX subcommittee to complete air tightness evaluation plan.
Approval of measure specifications
Decision DetailsApprove the Residential Weatherization Specifications developed by the Residential Weatherization Specification Subcommittee dated August 31, pending development of an inspection test with a sunset date of three years from the date of adoption of the inspector test.
Develop inspector tests; Identify any increase in cost for measure implementation
Direction for further analysis
Decision DetailsThe 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.
Approve measure update
Decision DetailsApproved UES values and costs for single family residential weatherization measures. This is approved as an active measure.
Direction for subcommittee
Decision DetailsAdvised the Residential Weatherization Subcommittee to base its ventilation requirements on the 2010 ASHRAE 62.2.
Approve measure update
Decision DetailsThe RTF accepted the deemed measure updates for existing single family homes.
