The HERS (Home Energy Rating System) Rating is the national standard for measuring residential energy efficiency.


It involves a complete measuring and computer modeling of your home's energy features, resulting in a score between 0-250.  The lower the score, the better.  A score of zero means you buy no energy 


If the goal of the rating is increased energy efficiency, we provide a prioritized list of simple energy efficiency improvements.  After improvements are made, a second rating can measure the effectiveness of the improvements and gives your home a final, certified HERS Score, the only nationally recognized score for your home's energy efficiency.  [see HERS Score in Building Science.]


The HERS Rating is also an integral part of certifying new homes for ...

  • ENERGY STAR New Homes

  • Code Compliance - 2012, 2015, 2018 International Energy Conservation Code

  • Energy Efficiency Tax Credit 

  • Enterprise Green Communities


The HERS Rating process involves visual inspection, diagnostic testing, and computer modeling of your home’s energy features - and a report of findings and improvement recommendations.


The Home Energy Rating  (HERS)  …

  • Reveals conditions in your home that are wasting energy.

  • Gives you the knowledge and specific steps to improve your energy efficiency.

  • Quantifies the energy impact and approximate cost of each suggested improvement, so you understand the “bang-for-the-buck” of each.   

  • Provides specifications for improvement work, to give you clarity when dealing with contractors.

  • Saves you money every month on reduced utility bills and longer equipment life.

  • Benefits you when you sell your home, as energy efficient homes with nationally recognized HERS Scores have higher resale values.

  • A HERS Rating is required in some cities in order to sell a house or even get a building permit.

  • It is required for a builder to get a $2,000 Energy Efficiency Tax Credit.
