What is the meaning of air infiltration?
Infiltration is the unintentional or accidental introduction of outside air into a building, typically through cracks in the building envelope and through use of doors for passage.
Infiltration is sometimes called air leakage.
The leakage of room air out of a building, intentionally or not, is called exfiltration.
How is air infiltration measured?
Air infiltration ratings have an average industry rating of ≤ . 30 cfm/sf (cubic feet per minute per square foot) against a 25-mph wind speed.
This rating is calculated by how many cubic feet of air can pass through a window in a matter of a minute's time.
That number is then divided by the total area of the window.
What is the rate of air changes per hour infiltration?
The rate of air infiltration into a building is often expressed as air changes per hour with typical values of ¼, ½ or 1 air change per hour.
The heating and cooling systems in buildings are sized to cater for the loads imposed by air infiltration under design external and internal conditions.
Infiltration or air leakage is uncontrolled ventilation whereby air is introduced into a building from outside.
Infiltration occurs through gaps of cracks in the building fabric as well as around poorly sealed windows and doors.

The building airtightness (air leaks in the building envelope) affects the infiltration and can be described by n50 parameter, indicating the volume of air being exchanged through the building envelope during one hour at a pressure difference of 50 Pa between indoor and outdoor environments.
