What is a Blower Door Test?
Professional energy auditors will use a blower door test to help determine a home's air tightness.  Following the test, you will then be able to figure where to concentrate your efforts to make your home more energy efficient. Closing up the cracks and gaps can reduce energy consumption due to air leakage, stop moisture condensation problems, stop uncomfortable drafts caused by cold or hot air leaking in from the outdoors, and make sure the home's air quality isn't too contaminated by indoor air pollution.


How Does a Blower Door Work?


There are two types of blower doors: calibrated and uncalibrated. It is important that auditors use a calibrated door, which has several gauges that measure the amount of air pulled out of the house by the fan. Uncalibrated blower doors can only locate leaks in homes and provide no method for determining the overall tightness of a building. The calibrated blower door's data allows the auditor to quantify the amount of air leakage and the effectiveness of any air-sealing job.
