In July 2016 Massachusetts amended its current building codes to include the 2015 IECC / ASHRAE 2013, which will become fully effective on January 2, 2016. The update includes state amendments for the base energy code (residential and commercial), as well as an updated stretch energy code.
Further amendments not incorporated for this current (Eighth) edition of the state building code, such as the renewable energy readiness provisions, will be reconsidered when Massachusetts later adopts the entire 2015 I-code package as its Ninth edition. UPDATE: Public hearings regarding adoption of the Ninth edition will be held on March 7, 2017 in Boston and March 14, 2017 in Springfield, each starting at 10am. Written comments are also being accepted. The public comment draft language includes language on solar ready roofs and EV charger ready wiring but otherwise does not change the adopted energy code.
NEW: Senate Bill 1771 would establish a zero net energy building standard for new residential construction by 2020 and for new commercial construction by 2030.
