What is a home energy audit?

Washington Energy | 09/17/2015 | Posted in Home energy audit

Have you ever wondered what it's like to have a home energy audit?

Come along as we follow a home energy specialist as he audits this Seattle home, originally built in the early 20th century. The house has had some upgrades since then, but the owner knew there was much more that could be done.


Enter Will Martinez – Home Performance Extraordinaire!

Will begins his Home Performance Audit

The audit begins with a test for leaks throughout the home including at the meter.

A lot of energy loss can be attributed to under-code insulation in the attic.

Attic Inspection Inspecting insulation levels

The great part for the homeowner is that you can explore your attic and crawlspace along with the auditor – without ever suiting up or leaving your seat. This live GoPro video feed allows the customer to ask their own questions about what’s going on in these areas of the home.

In addition to the outside meter, the water tank and the combustion system is checked for wasteful and potentially harmful gas leaks.

An area where homes lose efficiency (and homeowners lose a lot of money) is via leaky ductwork. Here, Will finds many opportunities for improvement. A well-sealed duct will not only prevent your conditioned air from escaping into unused spaces, but it will keep your system from working harder than it needs to.

Our infrared camera will find hot or cool spots in your home – opportunities to seal or insulate better. Combined with our blower door test (below) you can see in real time heat or cold air (depending on the season) escaping your home where you don’t want it to.

Using the IR camera

A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings.

Will and the homeowner are able to see the air coming in using a smoke pencil and by using an infrared camera.

Once Will collects all of the data he needs, he’ll head back to the home office and create a detailed 16-page report. The report provides the data collected during the audit and adds professional recommendations to make your home more efficient.
