Australia: NCC 2022 set to lift home energy efficiency

WOBO notes the home energy efficiency measures proposed by Australia.

Building Ministers have agreed to lift the energy standards of new homes through the National Construction Code (NCC).

As of NCC 2022, new homes and apartments will need to achieve the equivalent of “7 stars” NatHERS thermal performance.

A new annual energy use budget has been introduced for the first time.  The budget will apply to the home’s major appliances such as heating and cooling equipment, hot water systems, lighting, swimming pool pumps, and onsite renewable energy systems.

This is a significant step towards achieving zero energy and zero carbon buildings in Australia.

What’s next?

We’ll be releasing a preview of the new energy efficiency requirements on
1 September 2022.

NCC 2022 will be published in full on 1 October 2022 on NCC online.

The States and Territories will bring NCC 2022 into effect from 1 May 2023.

There will also be transition periods for specific requirement, including the:

  • New livable housing requirements; and new energy efficiency and condensation mitigation requirements – 1 October 2023
  • New low lead in plumbing product requirements – 1 September 2025.
