The Vermont Residential Building Energy Standard (RBES) - 30 V.S.A. § 51 affects all new homes built after July 1, 1998.

New RBES revisions took effect March 1, 2015 and apply to construction commenced on and after the effective date. RBES applies to all new residential construction, including additions, alterations, renovations, and repairs.

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.

Code Trainings


Blower Door Testing

The new Residential Stretch Code set to go into effect December 1, 2015 will require air leakage testing for those homes needing to meet Residential Stretch Code through the Act 250 process or in towns where Stretch Code is adopted as the base energy code standard. The requirement of  <3 air changes per hour at 50 Pascals (ACH50) must be measured through blower door testing. RESNET or BPI certified contractors can conduct the blower door test, and the Vermont Public Service Department is offering blower door certification trainings to builders interested in conducting this test on their own.  This training will cover the basics of obtaining a blower door measurement in new construction, but does not include the full range of air tightness diagnostics for existing homes. There is no fee to participate in this training.


The 4-hour training will include:

  • Process for preparing the home for safe and effective blower door testing
  • Hands-on demonstration of blower door equipment (set-up, fan, manometer, hoses)
  • Written certification test

Current dates include:

We are currently trying to schedule a training in northeastern Vermont and will post that date & location when available.
