Blower Door testing code Requirements

If you need Blower Door Testing in Jacksonville, Florida…call Misteraire! 
As per Florida Building Code sections R402.4.1.2 and R104.5, a mandatory blower door test must be performed by either individuals as defined in Section 553.993(5) or (7), F.S. or individuals licensed as set forth in Section 489.105(3)(f), (g), or (i) or an approved third party.

Each building must have 7 air changes per hour (7 ACH50) or less in order to successfully pass the Blower Door test.

Blower Door tests simulate the wind blowing against a building at 20 miles per hour, in which case the total volume of air within the house would be exchanged with outside air 7 times.  The 20mph wind is equivalent to 50 Pascals (Pa) of pressure difference.  A Blower Door Fan simulates these conditions during a test.

All buildings are tested at 50 Pa pressure difference to allow for comparisons to be made between homes/structures, no matter the size or plan type.  In the State of Florida, buildings which comprise of 3 stories or less must follow the building code with respect to these tests.

What is a blower door test?

Blower doors are used to measure the “air-tightness” of a home. In the 2015 and 2012-IECC, a maximum air leakage rate was defined and every home must meet set requirements with a blower door test performed by a certified professional.

How does a blower door test work?

The blower door is a powerful fan that mounts on the frame of an exterior door. The fan pulls air out of the house, lowering the overall air pressure inside. The higher outside air pressure is then allowed to flow in through any unsealed cracks and openings. These tests are used to determine the overall air “infiltration rate” of a building.

When do you perform a blower door test?

Blower door tests are usually performed at the end of construction projects, after basically anything that would be an unwanted leak needs to be sealed.

When our company performs blower door testing, rather than simply issuing a pass or fail, we will help to determine where the leaks are coming from.
