What Can You Expect With an Energy Audit? Part 2

The second step is the actual audit.

First, we review the homeowner’s goals and objectives.

Next, we tour the home and put it into winter mode. We close all of the windows and turn on all exhaust fans. The goal of this step is to depressurize the combustion zone, thereby setting up a worst case scenario before testing for CO (carbon monoxide) spillage.

Then, we set up a blower door and measure the rate of infiltration. When this is compared to the calculated rate, it can be determined just how much air sealing is needed.

If there are ducts, then a Duct Blaster is used to determine the amount of duct leakage. Using the Blower Door and Duct Blaster together enables us to measure the amount of leakage going outside of the conditioned space.

The data is then reviewed with the homeowner and qualitative recommendations are made.
