VT Building Energy Standards Update;

Residential (RBES) & Commercial (CBES)


Vermont law requires that the residential energy code (RBES) and the commercial energy code (CBES) be updated on appropriate schedules, the next update is currently underway and is expected to continue through 2014. This page shall be updated with all relevant information on the code update process including stakeholder meetings and drafts of the proposed updates.



On June 17, 2013, the Vermont legislature adopted Act 89, which clarifies the applicability of Vermont’s residential and commercial building energy codes to mixed-use buildings and includes various amendments to promote compliance with those codes, such as using existing State and local permit processes to encourage compliance.


Vermont’s First Stretch Code

Act 89 also amends the RBES statute to authorize the Vermont Public Service Department to adopt a “stretch” code for residential buildings to achieve greater energy savings than the baseline RBES. Once a stretch code is adopted, residential buildings will gain a presumption of compliance with the energy conservation criterion of Act 250 by complying with the stretch code. Additionally, the Vermont Public Service Department (PSD) is developing a “stretch” code for commercial buildings to achieve greater energy savings than the baseline CBES. Municipalities will have the option to adopt either or both stretch codes as part of their land use bylaws.


More Information

Four public meetings (in-person and via teleconference) will be held between February and June 2014. The first meetings will solicit feedback from interested stakeholders on the potential changes. Then a draft version of the updated Vermont RBES, CBES and stretch codes will be developed and presented at the later meetings for further comment.
