Energy 101: Home Energy Assessment

A home energy checkup helps owners determine where their house is losing energy and money - and how such problems can be corrected to make the home more energy efficient.

A home energy audit, also known as a home energy assessment, can help you understand the whole picture of your home's energy use. An audit can help you determine how much energy your home uses, where your home is losing energy, and which problem areas and fixes you should prioritize to make your home more efficient and comfortable. A home energy audit should be your first step before making energy-saving home improvements, as well as before adding a renewable energy system to your home.

Professional Home Energy Audits

A professional home energy audit will provide a thorough assessment of your home's energy use. In addition to a room-by-room examination of the home, an auditor may employ equipment such as blower doors, infrared cameras, and (rarely) PerFluorocarbon tracer gas.

Do-It-Yourself Home Energy Audits

While a professional energy audit provides the most complete picture of your home's energy use, a diligent self-assessment can help you pinpoint problem areas and prioritize your energy efficiency upgrades.
