HERS energy ratings are a crucial tool for homeowners and builders in Massachusetts. These ratings tell you exactly how energy-efficient a home is compared to a reference home. Understanding this rating is vital because it directly impacts your potential energy savings, property value, and comfort levels throughout the harsh New England seasons. In this blog, we will discuss what goes into an energy score, why it matters for your property, and how Heat Loss Management can help with energy assessments for your building.
What Exactly Is a HERS Energy Rating?
A HERS energy rating is a standardized scoring system established by the Residential Energy Services Network (RESNET) to measure a home's energy performance. The lower the score, the more energy-efficient the home is. For instance, a standard new home is typically assigned a score of 100, so a home with a score of 70 is 30% more efficient than that standard home. This assessment gives you a concrete number to reference rather than vague promises about energy efficiency.
To calculate this score, a certified rater performs a comprehensive energy assessment. They look at various factors that contribute to heat loss:
Air leakage: How much air escapes through cracks and gaps.
Insulation quality: The effectiveness of insulation in walls, ceilings, and floors.
Window efficiency: How well windows prevent heat transfer.
HVAC performance: The efficiency of heating, cooling, and water heating systems.
Why Should You Get an Energy Assessment?
Scheduling an energy assessment to obtain a HERS rating provides a clear roadmap for improving your home's performance. Many older homes in Massachusetts suffer from significant drafts and outdated insulation, leading to skyrocketing utility bills. By identifying these specific weaknesses, you can prioritize the renovations that offer the best return on investment.
Knowing your score empowers you to make smarter decisions about your property. Whether you are looking to sell your home or simply want to reduce your monthly expenses, an assessment clarifies the "invisible" costs of homeownership.

Do HERS Ratings Affect Property Value?
Yes, a favorable HERS energy rating can significantly boost the market value and appeal of a home. In today's real estate market, buyers are increasingly conscious of long-term operating costs. A home with a documented low HERS score proves to potential buyers that the property is affordable to heat in the winter and cool in the summer. It serves as a verified badge of quality that sets a listing apart from others in the neighborhood.
Beyond immediate resale value, energy-efficient homes often qualify for better financing options. By investing in improvements that lower your HERS score now, you are building equity and attractiveness into your property for the future.
