The purpose of 780 CMR 115, Appendix AA, is to provide a more
energy efficient alternative to the Base Energy Code applicable to
the relevant sections of the Building Code for new buildings.
INTERNATIONAL ENERGY CONSERVATION CODE (IECC)
The International Energy Conservation Code (IECC) is a building
energy code created by the International Code Council. It is a model
code adopted by many state and municipal governments in the United
States for the establishment of minimum design and construction requirements
for energy efficiency and is updated on a three-year cycle. The baseline
energy conservation requirements of the Massachusetts State Building
Code are the IECC with Massachusetts amendments, as approved by the
Board of Building Regulations and Standards.
STRETCH ENERGY CODE
Codified by the Board of Building Regulations and Standards
as 780 CMR 115, Appendix AA, of the Massachusetts Building Code, the
Stretch Energy Code is an appendix to the Massachusetts Building Code,
based on further amendments to the International Energy Conservation
Code (IECC) to improve the energy efficiency of buildings built to
this code.
This code applies to residential and commercial buildings. Buildings
not included in this scope shall comply with 780 CMR 115, Appendix
AA, as indicated.
A municipality seeking to ensure that construction within its
boundaries is designed and built above the energy efficiency requirements
of 780 CMR may mandate adherence to this appendix. 780 CMR 115; Appendix
AA, may be adopted or rescinded by any municipality in the commonwealth
in the manner prescribed by law.
The Stretch Code, as codified by the Board of Building Regulations and Standards as 780 CMR 115, Appendix AA, including any future editions, amendments or modifications, is herein incorporated by reference into the Code of the Town of Nantucket under the General Bylaws, Chapter
141, of the Town Code. The Stretch Code is enforceable by the Building Inspector and effective as of September 1, 2019.
