Construction concerns: Infiltration
from Fire Engineering
An air leak from outside that enters a building through cracks, doors, and other designed or undesigned openings is called "infiltration." It is one of the parameters used in designing heating, ventilating, and air-conditioning (HVAC) systems. The more resistant a building envelope is to the passage of unwanted, unconditioned outdoor air, the more energy efficient it will be.
