Determination of the airtightness of building envelopes by the fan depressurization method
Scope
This is a standard method of tests (SMOTs) for the determination of the airtightness of building envelopes. This
standard contains three test options, two types of assessments and, for attached zones, two pressure boundary
set-ups. The test options are the multi-point test, the two-point test and the single-point test. The types of assessments
are as-operated and closed-up. The pressure…
