The purpose of the Specialized Energy Code at 225 CMR 22.00
and 23.00, including Appendices RC and CC, is to provide a more energy
efficient and low greenhouse gas emissions alternative to the Stretch
Energy Code or the baseline Massachusetts Energy Code, applicable
to the relevant sections of the building code for both new construction
and existing buildings.
INTERNATIONAL ENERGY CONSERVATION CODE (IECC)
The International Energy Conservation Code (IECC), a building
energy code created by the International Code Council. The baseline
energy conservation requirements of the MA State Building Code are
the IECC with Massachusetts amendments, as approved by the Board of
Building Regulations and Standards and published in state regulations
as part of 780 CMR.
SPECIALIZED ENERGY CODE
The energy code codified by the entirety of 225 CMR 22 and
23 including Appendices RC and CC, including the residential and commercial
appendices added to the Massachusetts Stretch Energy Code, based on
amendments to the respective net-zero appendices of the IECC to incorporate
the energy efficiency of the Stretch Energy Code.
STRETCH ENERGY CODE
The energy code codified by the combination of 225 CMR 22
and 23 not including Appendices RC and CC.
