A home energy audit helps you learn how much energy your home uses and identifies ways to improve its efficiency. If you answer yes to any of these questions, an energy audit could help.
- Are your energy bills excessive?
- Are the floors cold in the winter?
- Is there moisture on the windows?
- Does the heating and cooling system run constantly?
- Are there drafty rooms or variable temperatures throughout the house?
- Is your home uncomfortable during hot and cold seasons?
- Do you have excessive dust?
Other times to consider an energy audit is before making a significant home improvement, such as replacing a furnace. Addressing air leaks ahead of time will increase the efficiency of your new HVAC system.
Planning a remodel? Having an audit completed before starting a remodel will help you plan and incorporate energy saving upgrades into your project.
A thorough inspection will provide you with a good understanding of your home’s energy efficiency, recommended improvements, and an idea of estimated costs and potential annual savings in energy bills. A professional audit can cost upwards of $400 or more but when used wisely can pay for itself in a short amount of time.
A professional auditor uses a variety of techniques and equipment to determine the energy efficiency of your home. A thorough audit will include:
- Blower Door Test (used to de-pressurize the home and expose air leaks)
- Infrared Camera Scan (reveals air infiltration and missing insulation)
- Combustion Safety Testing (detects carbon monoxide leaks)
- Complete Basement to Attic Inspection
- Survey of Appliances & Lighting Systems
The video Energy 101: Home Energy Assessment provided by the Department of Energy explains each of these steps in detail.
A Home Energy Auditor should be certified through either the Building Performance Institute (BPI) or Residential Energy Services Network (RESNET). Both BPI and RESNET have set standards for home energy professionals and are recognized by the Department of Energy and Environmental Protection Agency. Find a certified BPI accredited contractor near you.
If you are not ready to commit to a professional audit, there are things you can do on your own, such as caulk and weather strip around doors and windows, or wrap exposed water pipes. You can also conduct your own energy assessment. It won’t be as thorough as a professional audit, but it will help identify some of the more accessible areas and remedies.
Do-it-yourself audits are a good start but are no substitute for a professional home inspection. A home energy audit is an investment to help you determine the best steps to increase your home’s efficiency.
