An authorized Home Energy Assessor from Community Energy Project will come to your home and will take about sixty minutes to assess its energy use. The length of the assessment could vary based on the size of the building.

Your Assessor will visually inspect and ask questions about your home’s foundation, insulation, walls and windows as well as heating, cooling and hot water systems. They will not ask you questions about your personal energy use.

As the Home Energy Assessor conducts your assessment, they will enter the information they gather into the U.S. Department of Energy’s Home Energy Score software to score your home. This software analyzes your home’s energy use and produces a score based on criteria established by the Department of Energy, not by Community Energy Project or any third party. This ensures that all homes’ energy use can be compared fairly and objectively.

Your house’s energy use will be ranked on a scale of one to ten, in which five represents an average rate of home energy use and ten represents the most energy efficient home.

In addition to a numerical score, you will also get:

  • Information about your home’s energy profile based on the physical characteristics of your house, not your personal habits or preferences
  • An estimate of annual energy costs
  • Recommendations of how to improve the house’s energy efficiency

When your assessment is complete, CEP will provide you a copy of your report, which will also be available online at the Green Building Registry. You and your realtor can work together to incorporate your score into all home sale listings and ads.
