Single Family Performance Path transition to REM/Rate™ Version 15.7.1
Beginning on March 1, 2019, the Utility Incentive V2 – Single Family Performance Path program in AXIS will accept REM/Rate files created in version 15.7.1. Our teams worked extensively with Energy Trust of Oregon, Bonneville Power Administration, and the Regional Technical Forum to review and agree on the shift in REM/Rate versions.
There will be a six-month transition period, beginning on March 1 and ending on September 30, during which REM/Rate version 15.3 and 15.7.1 will be accepted in Performance Path. Homes with version 15.3 must be submitted for QA and certification in AXIS by September 30; QA and any corrections with version 15.3 will continue through October. Starting on October 1, only homes submitted with REM/Rate version 15.7.1 will be accepted.
Action items for raters/verifiers submitting Performance Path homes:
- Download the updated Modeling Requirements document and version 15.7.1 User Defined Reference Homes (UDRH) for REM/Rate from the BetterBuiltNW website. The website will maintain resources for both REM/Rate versions until the transition period ends.
- Connect REM/Rate 15.7.1 to AXIS. Review this Support Portal resource or reach out to the AXIS support team for assistance. Version 15.7.1 will use the same UDRH Export function to send files from REM/Rate to AXIS.
- In-progress homes will not be locked into using the older REM/Rate version 15.3. The REM/Rate file may be switched from 15.3 to 15.7.1 with rater discretion.
We understand national programs, like HERS, tend to require the most recent version of REM/Rate. Our regional utility programs must adhere to versions of REM/Rate that are vetted and approved by regional stakeholders. Reach out to Noresco or the REM/Rate Google Group for assistance on managing multiple versions on your computer.
