The Energy Rating Index (ERI) is new to the 2018 Building Code. It will allow builders to use a HERS Index Score to demonstrate a home’s compliance with the residential building code. So long as you meet or exceed the HERS Score for your climate zone, you’ll be allowed to use trade-offs from the prescriptive code. All homes permitted on or after July 1st, 2018 are eligible to use the new ERI option.
We think that builders will find the new ERI option to be an easier and more cost-effective alternative to the REScheck moving forward. Click here to read our full breakdown of the new ERI option
