Background

The most current versions of the Residential (RBES) and Commercial (CBES) Building Energy Standards became effective March 1, 2015. The current Standards were based on the International Energy Conservation Code (IECC), 2015. The IECC released updated standards earlier in 2018. Vermont statutes require that revisions be made promptly after the issuance of updated standards for residential construction under the IECC. In 2013, the Vermont legislature in Act 89 required the adoption of a stretch code for residential buildings to achieve greater energy savings than the baseline RBES. The Department, in partnership with the Natural Resources Board (NRB), also developed stretch guidelines for commercial buildings. Residential or commercial buildings that comply with the stretch code or guidelines, respectively, are presumed to comply with the energy conservation criterion 9(F) of Act 250. Municipalities have the option to adopt and include the stretch language for either residential or commercial buildings, or both, in the municipality’s land use bylaws.
