Subscribe to our RSS Feed How a Home Energy Audit Can Lead to a More Efficient Chicago Area Home

Monday, March 17, 2014

One of the best investments you can make for your home is an energy audit. These audits are performed by licensed energy auditors or HVAC professionals to find all the places inside your home where you're losing energy. As a result, you can quickly make your money back since your subsequent energy savings will cover the cost of an audit many times over. One major source of energy loss is caused by substantial air leakage that can account for significantly higher energy bills in a home.

What Is An Energy Audit?

A home energy audit leads to the discovery of air leaks and inadequate insulation, which greatly affect energy efficiency. Professionals generally use a blower door and thermographic equipment to discover air infiltration and thermal differences around your home. The blower door fits inside an exterior door frame and adjusts to form a tight seal. It has a large fan inside it, along with air pressure gauges.

How Does the Energy Audit Work?

The audit team readies your home for the home energy audit and then turns the blower on. Blowing outward, it pulls the air from your home and as it does, the pressure gauges fall. A home that has a lot of air leaks will regain pressure quickly, as air from outside quickly finds its way inside through cracks and openings in the walls and around doors and windows. If the home regains pressure slowly, it means that your home is closer to being airtight. 

While the fan is running, the technicians will walk through your home using the thermographic equipment that indicates temperature differences between the incoming air and that of your home. If outdoor temperatures are approximately the same as indoors, the team may use a different technique, like a harmless smoke pencil to show air movement. On the thermographic scan, areas in your home with inadequate insulation will show up as a different color, revealing where insulation needs to be added or upgraded.

Energy Audit Findings

Likely spots for air leaks in your home occur around window and exterior door frames, places where building materials meet, as well as in the attic and basement. Anyplace where pipes or wires exit your home, air can be leaking. Recessed lights that protrude into the attic can also result in air leaks. Fireplaces, dryers, vent stacks and chimneys may be sources of air leakage, too.
