What is a HERS Index?

There are plenty of ways to make your home more energy-efficient. As homeowners, you know that with every scheduled maintenance and every home purchase, there are ways to save energy, money, and have a more sustainable household. 

With all of the options available, it can be overwhelming to sort through what will help your home run more efficiently, and what isn’t necessary. That is where the HERS Index can help.

What is the HERS Index?

The Home Energy Rating System (HERS) Index is the nationally recognized system to assess a home’s energy performance. 

HERS scores are designed to calculate the energy efficiency of new or remodeled homes. If you are in the market to buy a brand new home, the HERS score will give you an idea of the energy costs for the house.

How do you find out the HERS Index Score?

A certified HERS Rater can determine the HERS Index Score of your home. They will complete an onsite energy rating of the home, and then compare the data to a reference home. The reference home is an analysis tool designed to resemble the actual house in size, shape, style, environment, and climate. 

What does the score mean?

The HERS Index ranges from 0 to 150, with 0 being a home that produces or conserves as much energy as it uses. While a score of 0 is unlikely, the lower the score, the more energy-efficient the home.

The standard new home typically has a rating of 100, while the typical resale home has a score of 130. Using these scores as reference points, you can get an idea of how efficient your home is. 

How can I improve my home’s HERS Index Score?

The greatest energy expenses in a house are for heating and cooling. Whether you are remodeling your entire home or just looking for a way to save on energy costs, you can get a programmable thermostat, upgrade your HVAC system, or simply get an annual tune-up to make sure it is working properly. 

Other energy-saving tips include: sealing all air leaks, add insulation, upgrade to ENERGY STAR appliances, and consider installing solar panels

A HERS index rating can help you determine what type of fixes will be most beneficial for your home.
