The 2022 version of the National Construction Code (NCC) is now available online.
The major changes are the lifting of the minimum energy efficiency requirements for new homes from 6 to 7 NatHERS stars, and a new annual energy-use budget applicable to major appliances such as space conditioning, hot water, lighting, pool and spa pumps, offset by any onsite renewable energy generation.
The NCC also uses a new structure and clause referencing system intended to improve useability.
NCC 2022 will be adopted on May 1, 2023, with transitional arrangements for some specific areas. New energy-efficiency and condensation mitigation requirements will begin on October 1, 2023. The same start date will apply to requirements for livable (accessible) housing.
In line with this, the changeover date for new testing requirements for passive fire protection systems has been pushed back to May 1, 2023. Previously, as of September 1, 2022, these systems were to be tested to the latest version of AS 1530.4.
Finally, new lead-free plumbing product requirements will begin on September 1, 2025.
Until these adoption dates, NCC 2019 Amendment 1 remains in force, though developers can start using the new code now. The Australian Building Codes Board (ABCB) has prepared information about using NCC 2022 before the adoption date, highlighting areas where special attention is required.
The ABCB plans to release more resources throughout the year, including in-depth articles on key changes, videos and webinars, updated guides to the NCC, supporting tools and calculators.
NCC 2022 can be accessed through the National Construction Code website.
