In Case You Missed It

Every month this section features must-read content from past newsletters – just in case you missed it.

EPSTM Quick Reference Guides Feature

Energy Trust of Oregon’s EPS New Construction offering recently released four quick reference guides on air sealing, duct sealing, ventilation, and insulation. The guides feature content in English and Spanish. Builders constructing homes to EPS standards can share the guides with their design installation teams to ensure that EPS requirements are met.

Energy Trust recommends including the guides in project plan sets and displaying them in highly visible areas on job sites. Visit Energy Trust’s Insider page to download PDFs of the four guides. To request physical copies of the guides to post on job sites, email

Programs in the News

Every month BetterBuiltNW highlights different programs in the news to keep builders and Raters/Verifiers informed about key updates, program changes, and features. This month’s Programs in the News features the following updates:

  • Northwest Modeling Requirements Update
  • Training Resources for New Codes in Idaho, Montana, Oregon, and Washington

Northwest Modeling Requirements Update

The BetterBuiltNW team recently updated the Northwest Modeling Requirements. This V21.0 guide provides raters with technical guidance on modeling homes in REM/Rate™v15.7.1 to generate Northwest utility approved savings estimates. Utilities can then use these savings estimates to meet conservation goals and issue incentives for qualified projects. These requirements also provide information about how data is uploaded to the regional new homes database (AXIS), and where supporting files are located. Version updates also include helpful guidance on modeling complex HVAC configurations.

This version is effective for participating utility programs in Idaho, Oregon, and Washington as follows:

  • Idaho: August 9, 2021
  • Oregon: October 1, 2021
  • Washington: October 1, 2021
