The Residential Building Energy Code (RBES for short):

Since 2009, the State of Vermont has had an Energy Code in place. It is applicable to all new and renovated homes (conditioned spaces). If you are building a new home or renovating an existing home you are required, by law, to follow the minimum R-value guidelines set forth in the RBES law (as summarized in the Handbook). You are also required to submit a completed RBES Certificate or a Vermont Owner/Builder Disclosure Statement with the Town or City where the project is located before you can obtain a Certificate of Occupancy.

The REBES is based upon the IEEC Code and is updated every three years. We are currently using the 2015 version.
