This Standard provides measurement of the air permeability of buildings or parts of buildings in the field to validate the designed thermal performance. It specifies the use of mechanical pressurization or depressurization of a building or part of a building.
It describes the measurement of the resulting air flow rates over a range of indoor-outdoor static pressure differences. This Standard also provides measurement of the air leakage of building envelopes of single-zone buildings.
