Vermont Building Energy Standards Update
Residential (RBES) & Commercial (CBES)
The Public Service Department (PSD) would like to thank all of those who participated in the energy code update meetings and provided valuable feedback to the drafts of the Residential Building Energy Standard (RBES) and the Commercial Building Energy Standard (CBES). We made numerous changes to the energy codes due to the feedback we received and believe the codes are much improved because of it.
The PSD has now adopted the final version of the energy codes and set the effective dates as follows:
- Residential Building Energy Standard Base - March 1, 2015
- Residential Building Energy Standard Stretch - December 1, 2015
- Commercial Building Energy Standard Base - March 1, 2015
Building Energy Standards, Draft Versions
These "Draft" versions represents the final code language as adopted by Vermont. The PSD is currently working with the ICC to complete the official formatted versions of RBES and CBES. The only changes that will be made between these final "Drafts" and the official copies will be to formatting, typos, numerical errors and internal references. We will make the final version available as soon as it is completed. Hardcopies of these draft codes can be provided upon request.

Code Historical Development Documents
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.
