Welcome to REM/Rate™

REM NEWS

• REM/Design™ has been decommissioned and will no longer be supported or authorized for use.

• It is being 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 support for pricing information.

• CRITICAL Change. Due to 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

2023 HotFix 2017 April 2025

• CRITICAL - fixed an issue occuring on some machines where Energy Star 3.2 will fail. The failure appears to be related to Windows security preventing REM/Rate from reading certain files. It now ignores reading those files.
• Fixed an issue with RESNET registry for airPlus.
