At e3 Power, we are offering the scoring tool at no additional cost to the homeowner if an infrared energy audit is completed for their home.  The total cost of the audit is $385.00.  The homeowner pays $185 at the time of the audit if you are an Excel Energy customer and meet certain other qualifications. (Most homeowners meet these qualifications).  We collect the remaining $200 directly from Xcel Energy through an assignment of rebate.  This scoring tool does not take the place of a comprehensive energy audit or a HERS Score.  

Home Energy Score (HES) - Explanation of the Score by the DOE

The Home Energy Score (HES) was developed by the Department of Energy to assess a home’s envelope and major energy systems.  It allows comparison between homes regardless of location the US.  The HES estimates the energy efficiency of a home based on a simple scale from 1 to 10, with 10 being the most efficient. It also provides an estimate utility bill savings and improved score if all recommendations are installed.

The homeowner receives

(1)    An Asset Score:  The score is a numerical score of  for the house on a scale of 1 to 10 with 10 being the most efficient

(2)    Home Facts: The square footage of the home, direction of the front door, insulation levels of the walls, ceiling and roof, foundation, window size and type and HVAC equipment

(3)    Improvement Recommendations: Customized recommendations based on the data entry for the house.

How is the score calculated?

·        The tools estimates total energy use for the home based on the assessor inputs and assuming certain standard conditions, such as thermostat settings  number of people and other factors

Does the scale adjust depending upon house size?

·        No. The 10 point scale is not adjusted for size, so, if all things are the same, a large house will score worse than a small one.


Does the score take into account weather?

·        Yes, a house in San Diego CA that scores a 5 will not use the same amount of energy as a house in Bangor, ME that also scores a 5.

Does the score take into account how much energy the current homeowner uses or recent utility bills?

·        No.  It does not account for the behavior of the home’s occupants.  Thermostat settings are standardized and baseloads such as lights, appliances and laundry are based on house size or the number of bedrooms.

How are the dollar savings estimated?

·        The tool calculates what a typical homeowner living in this house will save on their utility bills annually if all the recommendations are implemented.  The cost savings are based on state average utility rates.
