How Is A Blower Door Test Conducted?

In blower door test in Clinton township, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.
