(none)Measures without a Category have not been approved by the RTF, but they are listed here because they have been considered by the RTF.
PlanningUpon request, the RTF will consider the proposed planning measure and formulate a consensus opinion on the likely UES values. This process is intended to promote consistent treatment of these measures throughout the region. The RTF will also review and comment on any proposed research design for collecting data needed to support Provisional or Proven UES values. The review will only be provided if the section 3.2.1 UES quality criteria for Planning measures are satisfied. Measure specifications (section 2) and the information described in the Guidleines for UES measures must be provided before this review can commence.
ProvenMeasures can obtain approval for Proven status if the section 3.2.3 UES quality criteria for Proven measures are satisfied. Sunset criteria will be assigned by the RTF along with a plan for data collection and analysis that allows the UES estimate to be reviewed and updated in a timely fashion.
ProvisionalMeasures can obtain Provisional approval if the section 3.2.2 UES quality criteria for Provisional measures are satisfied. In addition, it must be possible during the provisional period to obtain the data and analyses needed to meet the Proven quality criteria (3.2.3). The data and analyses may come from programs delivering the measure or from other studies. The plan for completing the necessary data collection and analyses must be approved along with the provisional UES estimates. In addition, sunset criteria must be adopted that are consistent with the plan. For measures that require long periods to collect and analyze baseline and efficient case data, the plan should include staged analyses so that early experience with deployment, baseline conditions, and measure performance can be used to adjust the sunset criteria.
Small SaverThe RTF may determine that the likely savings from a measure are too small to warrant the resources needed to meet the section 3.2 UES quality criteria for Provisional or Proven status. In making this determination, the RTF will consider the size of the regional end use that is affected by the measure or the magnitude of the likely savings. Measure specifications (section 2) and the information described above for the proposed stage is required for small savers and must be provided before the RTF can designate a measure as a small saver. For small savers, the RTF may choose to convene an expert panel to consider the proposed measure and to formulate a consensus opinion on the likely UES values. This process is intended to promote consistent treatment of these measures throughout the region.
(none)The RTF has not set a status for these measures either because they have not been assigned a category or because they were deactivated prior to receiving a status.
(Under review for compliance w/ RTF Guidelines)These measures' energy savings were "deemed" by the RTF prior to operating under the new RTF Guidelines. The RTF plans to review these measures under the Guidelines by the end of 2012. During this transition period, the RTF intends for these measures to continue to be considered "RTF-approved."
ActiveThese measures have received approval by the RTF and have no other associated review pending.
DeactivatedIf the sunset criteria are met, and the new or revised UES estimates have not been approved, the RTF will deactivate the measure. This means that the UES estimates are no longer approved by the RTF. The RTF may decide to deactivate a measure before the sunset criteria is satisfied based on unanticipated factors, such as the adoption of new energy codes or the release of study results with findings that invalidate the UES values or the procedures for estimating those values.
Out-of-complianceThe RTF may determine that measures approved prior to the adoption of these guidelines do not comply with one or more requirements of these guidelines. The UES estimates for these measures will continue to be “RTF-Approved” if a plan for bringing the measure into compliance is approved by the RTF within one year following the RTF determination that the measure is out-of-compliance. If no plan is approved within one year, the measure will be de-activated. The RTF intends that all out-of-compliance measures will be reclassified, i.e., become a standard protocol or be placed in one of the UES measure development stages of small saver, planning, provisional, de-activated or active, as soon as possible, but no later than five years following the adoption of these guidelines.
Under ReviewAt any time prior to the sunset criteria being met, the RTF may decide to place a measure under review. This may be the result of a review of the UES savings estimation procedure or the availability of new sources of information for baseline or efficient-case consumption. The UES values will remain “RTF-Approved” while the measure is under review. As a result of the review, the UES values may be re-estimated and the measure sunset criteria revised.

RTF decisions

Decision (show decision details)

Approve SF and MH Residential Weatherization Infiltration Reduction. Change measure status to Active. (Infiltration measures to "Under Review" status).

Measure category unchanged

Measure status changed: Previous status - Active; New approved status - Active (Infiltration Reduction Measures: Under Review).

Energy savings unchanged

Cost effectiveness unchanged

Specifications/Eligibility unchanged

Planned future work: 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.


The 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.”

(No changes to status, energy savings, cost effectiveness or specifications.)


The RTF approved the Residential Weatherization Inspector Examination and method developed by the Residential Weatherization Specification Subcommittee.

Measure category unchanged

Measure status unchanged

Energy savings unchanged

Cost effectiveness unchanged: Inspection requirements may increase cost.

Specifications/Eligibility changed: Inspector exam approval initiates Residential Weatherization Specifications approved October 4, 2011. These specifications now apply to MF, MH, and SF Weatherization measures.

Planned future work: Res WX subcommittee to complete air tightness evaluation plan.


Approve 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.

Measure category unchanged

Measure status changed

Energy savings changed: To be determined

Cost effectiveness changed: Yes, cost of implementation estimated to rise

Specifications/Eligibility changed: Specifications more specific and requirements are better detailed

Planned future work: Develop inspector tests; Identify any increase in cost for measure implementation


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.

Measure category unchanged

Measure status unchanged

Energy savings unchanged
