Building Energy Standards

On December 5, Vermont finalized an update to its Residential and Commercial Building Energy Standards (RBES and CBES), thereby becoming the first state in the country to adopt* a building energy code based on the 2015 International Energy Conservation Code (2015 IECC). The 2015 IECC is the newest and most efficient version of the IECC, a model code used by the vast majority of the country (including every state in NEEP’s region).
