The measure installs a strip of flexible material at the bottom of an exterior door to reduce air infiltration. This saves energy by reducing heating/cooling losses by air sealing the gap under the door. Gap height has a significant impact on savings but is a substantial source of uncertainty because there are no sources for the 'average' door gap size. There are also no known sources on effective useful life, another source of uncertainty. To address this uncertainty the RTF adopted a research strategy aimed at collecting data on the existing door gap area. The strategy proposes doing this across housing types (multifamily, single family and manufactured homes) and across deliver channels (leave-behind, mail-by-request, and direct install) with specific focus on ensuring the door sweep is installed correctly.

Decided 
December 07, 2021
RTF Meeting: December 7-8, 2021

Adopt New Measure

Decision Details

Adopt the Residential Door Sweeps UES and associated Research Strategy as presented and:

  • Modify the MH door size to 32" in the analysis
  • Modify the measure specification to include 'doors that open to unconditioned spaces' instead of 'exterior'
  • Apply an install rate of 50% for mail-by-request measures
  • Assume an EUL of 5 years
  • Reduce the gap size from 1/2" to 1/4" in the analysis
  • Set the category to Planning
  • Set the status to Active
  • Set the sunset date to December 31, 2024. 
Decided 
December 17, 2019
RTF Meeting: December 17, 2019

Allocate Resources to New Measure Development

Decision Details

The RTF to allocate resources to the following measures:

  • Residential Door Sweeps
  • Commercial Heat Pump Water Heaters
  • ENERGY STAR Commercial Ice Makers and Storage Bins
  • ENERGY STAR Commercial Vending Machine
  • Lodging - Guest Room Controls
  • Variable Volume Lab Hood
  • Water Cooler Timer
  • Irrigation - Pressure Reduction
  • Compressed Air - additional applications
  • Chillers

Have CAT and staff work with the Implementer's Group to prioritize these measures.
