Prescriptive Duct Sealing Measure Proposal Presentation to the Regional Technical Forum August 20, 2013
Presentation Outline • Measure Overview • UES Analysis and Results • Research Plan • RTF Staff Review and Guidance • Proposed Decision
Measure Properties • Review the Measure Properties section on the “Summary” tab of the proposed measure workbook. • Planning Assumption: Measure properties & savings are equivalent to PTCS duct sealing.
Unit Energy Savings • Current UES values taken from existing RTF PTCS SF and MH duct sealing measures • The current UES values are calculated using SEEM with inputs from PTCS test data • Values taken for each heating zone, average of heating systems • The current MH UES values include a 12% reduction in savings to account for measure implementations where no savings result. • The current SF UES values do not include this savings reduction factor. For this measure, the reduction factor is included in the new SF UES.
Research Plan • Proposed UES estimation method is Calibrated Engineering Analysis • As per Guidelines, billing analysis is not recommended to develop savings for UES measures with significant interactive effects. • Billing regression analysis provides percentage savings, that is a key input for the Calibrated Engineering Analysis. • Recommended method will comply with last-measure-in. • Pre/post analysis for both a treatment and control group. • Treatment group will be the first cohort of participants • Control group will be a later cohort • Use the same pre and post period for both groups
RTF Staff Review and Guidance • RTF staff recommendation on research plan: • Research plan incorporates R&E Review Group feedback • Staff agrees with the plan but acknowledges the uncertainties associated with billing analysis • Estimates of expected confidence and precision based on CV observed in RBSA data. • RTF staff recommendation on the UES estimate: • Planning estimate reviewed by subcommittee. • Measure specifications reviewed and edited by subcommittee and staff • Staff recommends de-rating savings to account for lack of testing equipment-guided sealing (e.g. 25% less savings)
RTF Proposed Motion: “I _________ move that the RTF approve the UES measure Prescriptive Duct Sealing to the Planning category with Active status and a sunset date of December 31, 2015.”
