who is on the subcommittee

All members of the Residential Subcommittee are automatically volunteered to review the WX and Ventilation Specifications. Current members are:

Who is on the Subcommittee?

Subcommittee: Residential Weatherization and Ventilation Specifications

where we are

Ongoing review of Residential Weatherization Specifications

  • Last revision 2006, three year cycle is goal
  • Current Specifications reviewed and changes submitted
  • Including a comprehensive revision from BPA
  • Ventilation Standards tied to house tightening
    • Subcomm determined disclosure path best, with reference to ASHRAE or Nat’l Standard
  • Parallel Evolution
  • National Workforce Guidelines US DOE
  • IAQ Protocol from US EPA

Where we are

Subcommittee: Residential Weatherization and Ventilation Specifications

revisions to 2006 specifications

Changes:

Clarification of applicable codes and requirements – language clean-up

Clarification of approved materials, more reference to codes and manufacturer’s compliance

Revisions to 2006 Specifications

Subcommittee: Residential Weatherization and Ventilation Specifications

revisions to 2006 specifications1

Attics

      • Pre-sealing brought in from air seal separate measure
  • Kneewalls detailed
  • Hatches and Doors detailed
  • Extend exhaust fans to outdoors
  • Installer Certificate

Windows

Safety glass requirements deferred to Code, “protective bar in lieu” allowance deleted

NFRC U-Value remains at .30, .35 for patio doors

Language cleanup on frame assembly, durability

next steps recommendations

Weatherization

Merge and reformat 2006 Weatherization Specifications with BPA new proposed document format

Take out all “shoulds” and “recommendeds” and practices

Keep at a basic specification to achieve intended installation or measures

Suggest development of a Best Practices or Workforce Guide

And look at DOE document for opportunities to not re-create

Suggest development of a Field Guide for Compliance with Program Standards

in progress

Subcommittee has BPA proposed format, DOE and EPA documents to review and compare. Ventilation remains a hot topic.

The parallel evolution of other documents is an opportunity to mesh with a national effort and not reinvent – but only when it makes sense to do so.

Lots of talk around inspections, enforcement and training.

Tailor specifications to markets with differing workforce skill sets – i.e. prescriptive air sealing only where no Home Performance contractors serve.

Look toward whole-house / Home Performance-style measure bundles.
