Massachusetts has some of the most stringent energy efficiency requirements in the country. With the state continually pushing for a reduction in energy consumption and carbon emissions, building projects need to meet these tough standards. The HERS Rating helps to gauge a home’s efficiency and ensures it complies with local energy codes.
Home Energy Efficiency Consultants HERS Rating offers comprehensive services for homeowners, builders, and developers in Boston, MA, ensuring their properties meet these high standards while maximizing energy performance. We are a team of RESNET-certified HERS Raters, meaning we have received specialized training and accreditation to provide accurate, reliable HERS ratings that are widely recognized in the industry.
Our certified HERS Raters assist in every phase of your project—starting from the design phase to the final construction. With our involvement, you can be confident that your building will not only meet energy efficiency standards but also save you money in the long run through better energy usage and available rebates.
The HERS Rating System evaluates a home’s energy use by considering several factors that contribute to overall energy efficiency. A HERS Rater will assess each of these elements:
After evaluating these factors, the HERS Rater will assign a score based on the home’s energy efficiency. The lower the score, the more energy-efficient the home is. A home that achieves a score near 0 is considered to be highly energy-efficient, with minimal energy consumption, often incorporating solar power or other renewable energy sources.

A Home Energy Rating System (HERS) Rating measures a home’s energy efficiency. The lower the score, the more efficient the home.
Standard new home: ~100 HERS
Energy-efficient new construction: 50–70 HERS
Net Zero Energy home: 0 HERS
