Mass Save Energy Code Technical Support

The Massachusetts Stretch Energy Code, also known as the "Stretch Code", was made available for municipalities to adopt in 2009 as Appendix 110.aa and later as 115.aa within the building code found in 780 CMR. In 2021, new legislation was passed by the Massachusetts legislature, transferring the responsibility for updating the Stretch Code to the Department of Energy Resources and 225 CMR.

Starting from January 1, 2023, the Residential provisions of this code went into effect. The Commercial provisions went into effect on July 1, 2023. This code is intended to align with the upcoming 10th edition of the Massachusetts building code, which is established under 780 CMR.

The Massachusetts Stretch Energy Code 2023 is an amended version of the 2021 International Energy Conservation Code (IECC 2021).
