What is 'air leakage' 🧑‍🔧

In this article, I'd like to discuss "What is 'air leakage'". Let's look at what it is and how to respond to some frequently asked questions.

A quick answer is…

In ductwork, air which escapes from a joint, coupling, and such. Also: The undesired leakage or uncontrolled passage of air from a ventilation system.

’Air leakage’ is uncontrolled, accidental (due to poor design or maintenance) and is never needed.

’Air leakage’ can occur in any part of the condensing system which operates near or below atmospheric pressure, and is often caused by failure of joints, at flanges, and also by weld and material failures.

Do you know what makes people curious? Here are a few questions and answers:

Air leakage

Is your commercial building designed to reduce air leakage...

As building codes and owner expectations evolve, more commercial buildings across the United States are being designed to meet standards that reduce air leakage through the building enclosure. Some states are adding air tightness and testing requires to their building codes.

How does air leakage occur...

Air leakage happens when outside air enters and exits a building in an uncontrolled way. The main culprit is openings and cracks in the building roof and walls. When air exits a building through cracks in this way, we call it exfiltration. Infiltration is the opposite, the flow of atmospheric air into a building.
