Normalized Leakage Area (NLA)
The NLA is calculated by dividing the Equivalent Leakage Area (ELA) from a fan test by the area of the exterior envelope of the house. The ratio of the equivalent leakage area at 10 pascals (ELA@ 10 Pa) to the area of the building envelope, where the area of the building envelope is defined as all floors, walls (including doors and windows) and ceilings (flat or sloping) that are corresponding below, above, and adjacent to unheated spaces and spaces heated to less than 10 C, and are based on interior dimensions; express in cm^2/m^2 (sq. in/sq.ft).
