Since July 1, 2010, the energy conservation requirements of the MA State Building Code default to IECC 2009 with MA amendments. The amendments can be found at: Building Code/BBRS .

Stretch Energy Code

For communities that legally adopt the "Stretch Energy Code" (see 8 th Edition Building Code, Appendix 115.AA), the BBRS has set policy for implementation of this advanced energy code, as follows:

  • Training of Building Officials on Stretch Energy Code provisions prior to implementation,
  • Effective dates of either January 1 or July 1 of any given year, and
  • A "6 month concurrency period" requirement (as described above) beginning on the effective date.

In those communities that adopt the Stretch Energy Code, and after the 6 month concurrency period has elapsed, the Stretch Energy Code becomes the sole energy code in effect.
