What Happens During a Home Energy Audit?

Depending on the size of the home, professional energy audits can take anywhere from 30 minutes to four hours to perform.

FREMONT, CA: An energy audit is a house assessment that looks at current energy consumption and then recommends energy efficiency improvements one may implement to make the home more efficient. An energy auditor can determine where the home is wasting the most energy and give recommendations for energy-saving measures that will help save money on the electricity bills.

Depending on the size of the home, professional energy audits can take anywhere from 30 minutes to four hours to perform. These experienced auditors utilize a range of instruments to identify problem areas in the home and provide one with a list of recommended steps and actions that they need to take to make it more energy-efficient.

A typical energy audit in the home might look like this:

• From the exterior, an energy auditor will examine the structure. They will look at a range of components, including windows, walls, and eaves, to discover if any serious problems are causing leaks into or out of the property.
• The auditor will search into the attic (if owners have one) and examine a few items. Most importantly, they will examine the insulation to ensure that it is properly fitted and uniformly distributed between the walls. They will also check the holes where electrical wires run to see if they are adequately sealed or if they are a leakage source.
• The auditor will examine the furnace and water heater. If either is on the older side, it is probably time to upgrade. They will probably also inspect the furnace filter to make sure it does not need to be replaced. Further, they will inspect connections in the basement's ductwork for any probable leaks that could be causing you to lose heat and energy.
• A blower door test is usually included in professional audits. This is a device that helps them find air leaks in the house. All the windows and doors are closed during a blower door test, and they utilize a blower door machine to depressurize the house. The auditor then uses an infrared camera to determine where chilly air is entering the home.
• Finally, most audits involve a visual assessment of the home's lighting. If one is still using ordinary incandescent light bulbs, upgrading to light-emitting diodes (LEDs) or compact fluorescent lamps (CFLs) can help save money.
