Massachusetts is leading the charge in energy efficiency, and a big part of that is the evolving Home Energy Rating System (HERS) index. This system is a crucial tool for measuring and improving the energy performance of homes. But what exactly does it mean for you? Whether you’re a homeowner, builder, or just someone interested in sustainability? Let’s break it down.
What is a HERS Rating?
A HERS rating is a number typically between 0-100 that represents a home’s energy efficiency. The lower the number, the more energy-efficient the home. In 2022, the score required for new homes was 55, in 2023 it dropped to 52, and as of July 1, 2024 you need a score of 42 to pass.
Why is Massachusetts tightening HERS standards?
The Bay State has set ambitious goals to reduce greenhouse gas emissions and promote energy independence. By implementing stricter HERS requirements, Massachusetts is encouraging builders to construct homes that are more energy-efficient, comfortable, and cost-effective to operate. These new standards will mainly affect new constructions.
How does the new HERS rating impact you?
- Homeowners: Older, unimproved homes will often have HERS scores over 100. If you’re looking to resell your home with a high HERS score, you won’t be required to bring the score down first. However, if you do you could raise its value, because this information can be used by appraisers. Requirements aside, you should aim to score lower than 100 simply to save yourself some money in energy bills. Contact a certified Home Energy Rater in your area if you’d like to know your score.
- Builders: While there may be higher upfront costs associated with building to higher energy standards, the long-term benefits include increased market value for your homes and the satisfaction of building sustainable properties.
- Environment: By adopting stricter HERS standards, Massachusetts is taking a significant step towards reducing its carbon footprint and protecting the environment.
What a future with these HERS requirements will look like
With these requirements, Massachusetts aims for a shift away from fossil fuels and gas to more electric homes. This will be a major change to the way most homeowners heat and cool their houses. It also means:
- Electric stoves instead of gas
- Electric heat pump water heaters
- More air-source heat pumps and proper HVAC installations for central air in homes
- Energy Star appliances, windows, and doors eventually becoming the norm
Being home to some of the oldest houses in the country, you can probably see why the state would be interested in reducing its carbon footprint. According to census data on mass.gov, more than 80% of MA homes are heated by gas, oil, or other fuel, with only 18% using electric or solar powered heat.
Massachusetts’ commitment to energy efficiency is setting a strong example for the rest of the country. By understanding and embracing the new HERS rating system, we can all contribute to a greener and more sustainable future.
