Frequently Asked Questions
HERS Ratings & Blower Door Testing in Massachusetts
What is a HERS rating?
A HERS (Home Energy Rating System) rating is a standardized measurement of a home's energy efficiency. A certified rater evaluates insulation, air sealing, windows, HVAC, and other factors, then assigns a score. A lower score means a more energy-efficient home, and the rating is often required for code compliance and rebate programs in Massachusetts.
What is a blower door test and why do I need one?
A blower door test measures how much air leaks through a building's envelope using a calibrated fan installed in an exterior doorway. The result, reported in ACH50, shows how airtight the building is. In Massachusetts, blower door testing is commonly required for new construction, additions, and renovations to demonstrate energy code compliance and to pass final inspection.
Do I need a HERS rating to comply with the Massachusetts Stretch Energy Code?
Many projects following the Massachusetts Stretch Energy Code use a HERS rating as part of the performance compliance path. The required approach depends on your project type, municipality, and chosen compliance pathway. We help you confirm what is needed before you order equipment or schedule your final inspection.
Can blower door testing help me qualify for Mass Save rebates?
Yes. Blower door results and HERS ratings are often used to document building performance for projects tied to Mass Save and other energy-efficiency incentives. Because programs vary by utility and project year, it is best to coordinate testing with your overall compliance and rebate strategy early in the project.
