Vermont regulators who are rewriting the state’s building energy codes have adopted a revolutionary and progressive approach, providing new evidence that Vermonters are at the cutting edge of building code development and climate change action. This news is evidence that sometimes, small states can lead the way.

That said, the proposed changes will make the Vermont version so different from the IECC that it’s almost a new code.
At the Better Buildings by Design conference in Burlington, Vermont, on February 7, 2019, two energy code specialists (Richard Faesy and David Keefe) gave a presentation on the code revision process. “Vermont has a comprehensive energy plan requiring designing for net zero by 2030,” Faesy told the audience. “That’s one of the goalposts we are striving for, so we’re asking, ‘What will we have to do each step of the way to get there?’”
