Do I Need an Energy Audit?

If you are still not sure if an energy audit is for you, answer the following questions:

  1. Are you remodeling?
  2. Do you want to “go green”?
  3. Do you have high utility bills?
  4. Are you interested in energy efficiency?

What Exactly is an Energy Audits

An energy audit is an inspection and analysis of your property. The main purpose of this type of inspection is to determine the efficiency of your home. This may involve a room-by-room examination of your home. It also involves the analysis of several characteristics of your home, including the windows, ceiling, floors, doors, and more.

Many professional assessments will include the following methods:

  • blower door test
  • thermographic scan

A “blower door” is a machine used to physically locate air leaks. The blower door fan is temporarily sealed into an exterior doorway using the door panel system. All the interior doors are opened, exterior doors are closed, and some other preparations are made. Once ready, the blower door fan blows air into or out of the home, creating either a positive or negative pressure differential that can be measured. It can also be used to test ductwork airtightness and measure airflow between zones.

A thermographic inspection makes use of an infrared scanning device to detect temperature variations on the interior or exterior of your property. The images collected by this device will help to determine whether or not insulation is required in certain areas.

Once testing has been completed, a written report estimating the energy efficiency of your home will be completed by the professional who did the audit. The report will take into consideration factors such as the local climate criteria, roof overhang, as well as solar orientation.

The auditor will also take other factors into consideration such as:

  • How many people live in the home?
  • Is anyone home during working hours?
  • Are there any areas not being used?
  • What are the average thermostat settings for summer and winter?

How To Find The Best Auditor

It’s extremely important that you find a licensed professional to do the energy audit for you. Luckily, there are several options available if you would like to have an energy audit performed on your property.

Your state or local government should be able to assist you with a list of certified professionals who should be able to assist you. You can also consult The Residential Energy Services Network. This directory will be able to put you in touch with a local professional.

However, be sure to compare at least 3 estimates to ensure you get a feel for the current pricing trends in your region. Always keep in mind when you do this, however, that not every person who is willing to quote you may be a licensed professional. You should always check references before you go ahead and do business with anyone.


Remember, the only way to ensure that an energy audit is going to save you money is by having done right, the first time. By taking some time to select the right professional for your audit you will be saving yourself more money down the line.

  • clear space for access to crawl space, knee wall, or other access hatches

Make a list of all the issues you may be experiencing. This may include things like drafty rooms or areas where condensation is a problem. Also be sure to have copies of your monthly utility bills on hand for the auditor to scrutinize.
