HERS Rating vs ENERGY STAR: Which Do Massachusetts Builders Need?
Many Massachusetts builders ask: do I need a HERS Rating, ENERGY STAR certification, or both? This guide clarifies the difference and when each is required for new construction in Massachusetts.
What is a HERS Rating?
A HERS Rating is a numeric score (lower = more efficient) required for new construction energy code compliance in Massachusetts. It is mandatory in all MA Stretch Code municipalities. A RESNET-certified rater like HERS Rating Company performs the rating, including blower door and duct leakage tests.
What is ENERGY STAR for New Homes?
ENERGY STAR for New Homes is a voluntary certification program administered by the EPA. Homes must achieve a HERS score of 57 or below (v3.2) and meet additional requirements. ENERGY STAR certification is not required by Massachusetts code but can qualify for Mass Save rebates and is a marketing differentiator for builders.
Do I Need Both in Massachusetts?
Most Massachusetts builders need only a HERS Rating for code compliance. ENERGY STAR is optional but valuable for marketing and additional rebates. HERS Rating Company can help with both — our HERS Rating process naturally positions most homes for ENERGY STAR certification. Call 617-584-1809 for a free consultation.
