How Is A Blower Door Test Conducted?

A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.
