Announcing immediate availability of REM/Rate™ 2025

REM/Rate™ 2025 has been released and has the following new features:

• The latest NREL engine using ANSI/RESNET/ICC 301-2022 standard
• CFIS input improvements
• UEF added to DHW
• Adjustments to eaves impact on insulation on buildings with a vented attic
• Documents and photos can be attached to the building file, including rater checklists, Energy Star required photos, QA reports, etc.
• Numerous internal fixes that improve stability and allow for planned enhancements within the REM/Rate™ 2025 life cycle. IECC 2024, Energy Star 3.3 and ZERH2 will use this new framework with ZERH2 near completion.

REM/Rate™ 2023 is in maintenance mode

• Only critical bug fixes and crashes will be fixed.

REM/Rate™ 16.3.4 is end of life

• The installer for 16.3.4 has been removed from the remrate.com website. It can still be requested by contacting REM Support.

REM/Design™ has been decomissioned

• It is no longer supported or authorized for use
• It has been replaced by REM/Rate™ Lite. This ensures a single code base that implements all the code standards and bug fixes for a more consistent product. Contact REM Support for pricing information.

CRITICAL: New binding guidance from DOE and EPA

• Due to new guidance from DOE and EPA, REM/Rate™ Lite will no longer support the Energy Star Single-Family New Homes program and U.S. DOE Zero Energy Ready Homes program. For a home to be certified to these programs, the third-party verifier must be overseen by a Home Certification Organization (HCO). Because REM/ Rate™ Lite does not have the capability to track whether third-party verifiers are operating under an HCO , the ability to generate reports, labels, and certificates for these programs has been removed. Third-party verifiers working under RESNET’s HCO and REM/Rate™ may continue to use the full version of REM/Rate™ to certify homes to these programs.
• Both Energy Star and ZERH reports will be either disabled or rendered NO PRINT in REM/Rate™ Lite depending on the version. All other reports and standards will continue to be supported.

HotFixes

The Navigation control can be used to get to the corresponding building screen by simply clicking on any of the entries. It also contains related information between screens. For example, AGWalls contain the windows and doors attached to them. Additionally, each entry not only contains the screen values but the library values. These values are automatically synced with the page value. Other Navigation features include the ability to right-click to expand, collapse, print, and save the navigation control. This gives a complete view of the building without going through screens.
