What is a HERS score and why does it matter? (HOME ENERGY RATING SYSTEM)

Updated: Jul 14


Home Energy Rating System HERS scale

What does HERS mean?

  • HERS is an acronym for “Home Energy Rating System” It is designed to measure your new homes energy efficiency as it compares to industry standards.

  • Here is an example: a HERS score of 100 would be the average score for a new home built to code in the USA, the lower the number goes the more efficient the home is in comparison to the same home built to code.

  • Each 1-point decrease in the HERS Index corresponds to a 1% reduction in energy consumption.

  • Minnesota builders in general do very well at building an energy efficient home and come in at an average HERS score of 58.

What score does S&S average at?

  • Style & Structure is proud to say we have an average closer to 48 which makes us 52% more efficient than our national peers and 10% more efficient our local competitors.

  • Style & Structure is also a "Designated Green Path Builder" which means in addition to city inspections, we hire a third party inspection at framing completion to inspect the building envelope, another at insulation completion, and a "blower door test" at the end of construction to test the home for possible air leakage and vulnerable areas of energy loss.


What do they look for when scoring for HERS?

The HERS score takes into consideration many things:

  • The R-value of the walls and ceilings

  • energy efficiency of appliances

  • energy efficiency of lights bulbs

  • energy efficiency of windows

  • energy efficiency of mechanical systems.
