There are some reasons for establishing the proper building tightness:
A blower door is a device used to measure the exact air-tightness of a home. In the 2015 and 2012-IECC, a maximum air leakage rate is defined and each home must meet this tightness level verified with a blower door test.
A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings these tests determine the air infiltration rate of a building. Blower doors consists of a frame and flexible or hard panels that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow.
Blower door testing is typically performed at the end of construction, once the house is completely dried in, all penetrations sealed, lighting trim kits installed - basically anything that would be an unwanted leak needs to be sealed. When we do blower door testing, we won't just pass or fail a home - if the home doesn't meet the air leakage requirements, we will help to determine where the key leakage areas are using infra-red (IR) camera technology and/or theatrical smoke.
Take the following steps to prepare your home for a blower door test:
If you heat with wood, be sure all fires are completely out - not even coals - before the auditor arrives. Remove any ashes from open fireplaces.
Plan to do a walk-through of your home with the auditor. Be prepared to point out areas that you know are drafty or difficult to condition comfortably.
Expect the auditor to request access to all areas of your home including closets, built-in cabinets, attics, crawl spaces, and any unused rooms.
The auditor will need to close all exterior doors and windows, open all interior doors, and close any fireplace dampers, doors, and woodstove air inlets.
Expect the auditor to set controls on all atmospheric fossil fuel appliances to ensure that they do not fire during the test. The auditor should return them to the original position after the test.
Expect the test to take up to an hour or more, depending on the complexity of your home.
