What Is the Massachusetts Stretch Energy Code?

The Massachusetts Stretch Energy Code is an optional appendix to the base Massachusetts energy code that sets higher performance standards for buildings. Since its adoption, the Stretch Code has become mandatory in most Massachusetts communities — including Lunenburg — and is based on IECC 2021 with Massachusetts amendments.

The Stretch Code requires third-party verification by a certified HERS rater for all new residential construction. Key requirements include: maximum air leakage of 3.0 ACH50, duct leakage limits, minimum HERS Index scores, and mandatory blower door and duct leakage testing.
