Energy Conservation Regulation
Energy Conservation & Efficiency Regulation
Section J of the Building Code of Australia (BCA) details energy efficiency measures for various classes of building to ensure that energy is conserved and consumed in a sustainable manner to reduce greenhouse gas emissions.
Section J3.4.C. Specifies various draft-proofing measures for windows and doors and requires that a seal is fitted to restrict air infiltration for doors forming part of the envelope of a conditioned space, or the external fabric of a habitable room or a public area in climate zones 4, 5, 6, 7 or 8. It should be noted that fire doors, smoke doors and windows complying with AS2047 are exempt from these requirements and that States & Territories also enact their own energy efficiency regulation to cater for regional climates - so it is recommended to check local requirements with authorities having jurisdiction.
