How Was the Home Energy Score Created?

The U.S. Department of Energy’s formula for estimating a home’s energy consumption was used to create the energy report program. Every room in your home is measured and assigned a number during an energy audit, with 10 being the maximum efficiency. An energy audit typically receives a rating of about 5. This analysis takes into account both the estimated cost of energy and the quantity of energy utilized in your home. The score offers residents a list of solutions that they can choose to pursue and that they can complete in ten years or less. Assessments can also be used to rate projects according to associated expenses for homeowners.

Professionals certified by the Department of Energy, known as home energy auditors, will conduct an energy audit at your home. Certified contractors, home inspectors, or experts in the field of providing energy audits to customers are some examples of home energy auditors. In order to score your property based on its energy efficiency, these experts go about your home while doing an energy report, gathering a lot of data along the way.

What is inspected as part of the Home Energy Audit?

The HES includes the following tasks:

  • Calculating the house’s and the foundation’s square footage
  • Examining the size and effectiveness of the energy systems you presently use, such as your space heater, hot water heater, and air conditioner
  • Figuring out how many windows there are and their thickness
  • The thickness of insulation in the crawlspace, walls, and attic
  • Examining the electrical panel
  • Checking the air sealing around penetrations and seams
  • The state of the air ducts

These items are optional:

  • Checking for leaks in your space heating system with a duct blaster (most ducts leak up to 30%)
  • In an hour, utilize the Blower Door Test to see how the air in your home has changed. Air leaks can be greatly exacerbated by leaks that commonly occur in locations such as electrical outlets, above stoves, fireplaces, and even windows. In a house, two air changes per hour is the ideal number; however, five to ten typically occur.

Furthermore, details such as an approximation of the overall energy usage contingent on the type of fuel, operational parameters, and occupant conduct will be provided.

What Do They Do With the Information from Home Energy Audits?

After this assessment, these experts in home energy audits will be able to present you with a personalized list of excellent recommendations for affordable home repairs, an estimate of the annual savings, a return on investment, and an efficiency score ranging from 1 to 10. You will be aware of the energy efficiency of your home and any upgrades you can make to your current appliances and new equipment (such as a high-efficiency furnace or air conditioner) that can increase your home’s energy efficiency rating.

Home energy auditors can also provide property owners a sneak peek at their potential Home Energy Score based on the results of the audit, should they choose to implement the suggested solutions for energy waste. Performing the high-quality, energy-efficient modifications that the test recommends might raise your home’s score from a current 3 to a 7.
