Building regulations and associated standards
Building regulations exist to ensure the safety and comfort of building users. In Australia’s States and Territories, this is regulated via the provisions outlined in the Building Code of Australia (BCA).
The BCA recognises the need to reduce greenhouse gases and use energy in a more sustainable manner. It includes several sections directly relating to the Conservation of Energy and Weather Exclusion.
Section J Part J3.4.c provides guidance on energy-efficiency measures – and specifically the draft-proofing treatment for doors that form part of a building envelope or a conditioned space or public area in climate zones 4, 5, 6, 7 and 8.
It should be noted that the BCA sets out specific guidelines for energy efficiency in buildings – however, large climatic variances mean that Australian States and Territories apply their own Building Control Acts. These frequently specify regional energy efficiency schemes and requirements, so please check with your local regulatory authority about regulations for your location.
