Adjustable, passive vents by means of Home windows or walls could be put in to introduce fresh air rather then count on leaks during the developing envelope.
For household structures, which largely count on infiltration for meeting their ventilation requires, a standard ventilation fee measure will be the air change level (or air improvements for each hour): the hourly ventilation price divided by the quantity on the Area (I or ACH; models of 1/h).
