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 construct the Home Energy Assessment program in order to encourage people to save energy and reduce their carbon footprint. Every room in your home is assessed and assigned a number during an energy survey; 10 is the highest efficiency. An energy audit typically receives a rating of about 5. This analysis takes into account both the anticipated cost of energy and the amount of energy utilized in your home. The score can be completed in ten years or less and offers citizens a list of options to think about. Additionally, each project can be ranked according to the costs property owners will bear by using Home Energy Assessments.

Home energy auditors, who are professionals certified by the DOE, will conduct an energy survey of your residence. Certified contractors, home inspectors, and experts in the field of providing energy audits to clients are examples of home energy auditors. As they conduct an energy assessment of your home, these energy consultants gather a lot of information.

What is inspected as part of the Home Energy Assessment in Tiburon, CA?

The HES includes the following tasks:

  • Calculating the house’s and the foundation’s square footage
  • Evaluating the size and effectiveness of the energy systems you now use, such as your hot water heater, space heater, and air conditioner
  • Counting the number of windows and their thickness
  • The thickness of the insulation in the crawlspace, walls, and attic
  • Examining the electrical panel
  • Examining 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%).
  • Check if your home’s air quality has changed in an hour by using the Blower Door Test. Existing air leaks can be severely exacerbated by leaks that regularly occur in locations such as electrical outlets, above stoves, fireplaces, and even windows. In a residential setting, two air changes per hour is optimal; typically, five to ten occur.
