DUCT AIR LEKAGE
Why is ventilation compliance not being met across the industry, and what is contributing to this non-compliance?
It is Not a matter of compliance. The right question is more like, “Why the systems are not performing as designed?” The NCC does not demand any proof of performance by empirical test (the test is prescribed in AS4254.2 2012 but that section of AS is subsequently excluded from the NCC requirements in 2015 – in the explanatory note, so it is technically a grey area as the explanatory note is NOT enforceable). Traditionally, the compliance issue has always been dault with using deem to satisfied methods. As long as the duct manufacturers and installers only have to follow the prescribed methods and procedures for compliance. In the past, only special buildings may prescribe pressure testing of ductworks by the mechanical consultants.
