Building Energy Standards Update

Vermont Building Energy Code Public Stakeholder Meetings

The Public Service Department is beginning the next update to the building energy codes (Residential Building Energy Standards, or RBES, and Commercial Building Energy Standards, or CBES) with the target effective date of fall or winter of 2023. The code update process will include multiple opportunities to provide input and feedback.

The Vermont Building Energy Code Public Stakeholder Meetings are part of that process. The public stakeholder meetings will serve to gather input and feedback from a range of stakeholders in the process of updating the codes.

There will be two RBES public stakeholder meetings and two CBES public stakeholder meetings. The first set of meetings will present the proposed changes and gather input from the public for the development of the draft 2023 RBES and CBES. The second set of meetings will present the final draft of the proposed 2023 RBES and CBES codes and solicit feedback. These meetings will take place in April and late May and will be held remotely. 

Please join us for the second set of public stakeholder meetings the week of May 23. Below are the dates and times of the meetings.
RBES Public Stakeholder Meeting #2: Tuesday, May 24 from 2-4 pm
CBES Public Stakeholder Meeting #2: Thursday, May 26 from 2-4 pm

If you are interested in attending either or both of these meetings, please register. Click here to register for the RBES meeting. Click here to register for the CBES meeting.

Background

The most current versions of the Residential (RBES) and Commercial (CBES) Building Energy Standards became effective September 1, 2020. The current Residential Standards were based on the International Energy Conservation Code (IECC), 2015 with additional language from the International Energy Conservation Code (IECC), 2018 and International Energy Conservation Code (IECC), 2021. The Commercial Standards were based on the International Energy Conservation Code (IECC), 2018 with additional language from the International Energy Conservation Code (IECC), 2021. Vermont statutes require that revisions be made promptly after the issuance of updated standards. 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. 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.Adopted Rule Documents
