A comprehensive home energy audit is a service provided by a professional auditor
who will use a variety of diagnostic tools and industry standard tests to determine
the energy efficiency of your home. Along with an analysis of past utility bills,
the following are some of the tools and room by room examination services a professional
auditor can provide:
- A blower door which measures the extent of leaks in your building
- An infrared camera which shows heating and cooling problems caused by missing or
poorly functioning insulation, difficult to detect air leaks and other sources of
hot or cold air finding its way in and out of your home.
- A duct blaster which tests the level of leakage in your HVAC duct system (a significant
percentage of your heated or cooled air can be lost to the outside in this way.)
- A flow hood which tests whether enough air is traveling through room vents.
Once all testing is completed, the auditor will provide a detailed report outlining
specific, prioritized recommendations for the building based on energy savings and
cost of any recommended work. See the Energy Star or Energy Saver websites for more detailed information.
There are a number of organizations that certify and/or train home energy auditors,
including the Building Performance Institute (BPI), California Building Performance
Contractors Association (CBPCA), CalCERTS or RESNET. Listings of BPI or HERS certified
energy auditors and contractors are available from these websites:
