Submit Blower Door Tests
Tests must include:
Calculations of envelope area (calculations of volume are additionally helpful but not required). Calculations of at least one building must be measured manually on-site (not from plans). Envelope calculations of other two buildings may be either manual or off building plans.
Test results must be expressed in units of permeability, airflow at 50 Pascals per unit of building envelope surface area (i.e. m3·hr-1·m-2 @ 50Pa). Calculations of air change rate (e.g. ACH50 or n50) are optional but not required.
Tests must meet the requirements of standard AS/NZS ISO 9972:2015 or equivalent for this review.
These tests and calculations must be conducted on buildings not already in the Lodgement database.
Guidance on calculating envelope areas is available from ATTMA TSL1, TSL2, or TSL4, available from the ATTMA website.
