Following up on my post dated November 15, 2012, as of July 1, 2014, the International Energy Conservation Code (“IECC”) 2012 went into effect, replacing the former baseline building energy code regulations. The Commonwealth’s adoption of the updated code is meant to improve energy efficiency by 20% above the IECC 2009 and to bring communities that have not adopted the stretch energy code roughly up to the level of the communities that have adopted the stretch code’s more energy efficient regulations. The new regulations have no impact on communities that have adopted the stretch code, which was modeled after the IECC 2009. However, all building permits for non-stretch communities will be required to comply with the new baseline regulations going forward.
Among the changes are heightened standards for insulation and fenestration, eave restrictions, pipe insulation, and increased Heating Energy Rating System (“HERS”) requirements. The revisions will affect all phases of the building process, including design, construction and inspection. Responsibility for determining compliance with the new code provisions will remain with the municipal building inspectors.
The response thus far from the building community has been mixed. Here is a take from Guy Webb, the Executive Director of the Home Builders & Remodelers Association of Central Massachusetts:
While nobody is opposed to the increased energy efficiency that comes with the 2012 IECC, there are some negative aspects to the new code. First, the cost of compliance for an average size single family home is approximately $11,000, driving the already expensive price of a new home even higher. Second, the challenge that any new code poses to the building community exists with this code, with some additional challenges. Chief among them is that houses will now have to meet a much tougher standard of air tightness – down to 3 air changes per hour from 7 in the previous code. Another concern for builders is the rapidity in which the energy code changes in Massachusetts. There is a learning curve that both builders and building officials must conquer before things start to go smoothly. For the coming months we expect there to be occasional issues in the permitting and inspection processes. And then, once everyone is safely over the learning curve, we will be faced with the 2015 IECC.
