Overview

The Vermont Residential Building Energy Standard (RBES) - 30 V.S.A. § 51 affects all new homes built after July 1, 1998. It is the energy code for all residential buildings 3 stories or less above grade in Vermont.

The new 2020 RBES took effect on September 1, 2020, and applies to construction commenced on or after the effective date. RBES applies to all new residential construction, including additions, alterations, renovations, and repairs.  This effective date applies to both the RBES Base code and the RBES Stretch code. The RBES Stretch code is used to satisfy criterion 9(f) of all Act 250 projects.
