ME Building Energy Code

 

The Maine Office of the State Fire Marshal and the Maine Uniform Building Energy Code (MUBEC) Board is nearing completion of updates to the state's energy code. Maine’s new statewide base energy code, the 2015 IECC, will go into effect on July 1, 2021 for all new home and building construction statewide. Maine builders and contractors can still use the previous edition of the energy code, the 2009 IECC, until July 1, at which point all new construction must comply with the 2015 IECC. Few amendments were made to the energy code - you can view the model code online here.

The Office of the State Fire Marshal and MUBEC Board have also adopted a statewide stretch code: an additional, optional alternative to the 2015 IECC. Municipalities in Maine can instead decide to adopt the 2021 IECC stretch code as their energy code, which is ~15% more energy efficient than the 2015 IECC and includes options for achieving zero energy homes and buildings. Maine is offering these two codes so that municipalities who want to improve the energy efficiency, carbon footprint, and cost-effectiveness of their building stock beyond the levels of the state's base energy code can do so using a state-approved stretch energy code. Annual utility bills are one of the highest costs for home owners and renters, while Maine's homes and buildings produce nearly one-third of the state's annual carbon emissions. The stretch code provides communities the opportunity to save Mainers money on utility bills and lower carbon emissions, helping the state to achieve its climate goals at little to no extra cost. The stretch code is still undergoing rulemaking but will be available on or before July 1, 2021.
