Energy code does not only apply to new homes. Additions and major renovations in Massachusetts often trigger compliance requirements too.
When Code Applies
Adding conditioned space or substantially altering the building envelope typically brings a project under energy code. The scope of work determines which requirements apply.
Testing Considerations
Depending on the project, +blower door testing or other verification may be required for the affected areas. Connecting new and existing construction carefully helps maintain a continuous air barrier.
Common Challenges
Tying into older, leakier construction can be tricky. A thoughtful approach to insulation and air sealing at the transition points protects performance and avoids moisture issues.
