NCC 2022 Software Transitional Arrangements

The National Construction Code (NCC) 2022 came into effect on 1 May 2023. Some states and territories have opted to delay adoption of the updated energy efficiency requirements or set an extended transition period. 

The Australian Building Codes Board (ABCB) has a useful table referencing adoption dates across states and territories.

NatHERS software guidance

To help streamline requests during the extended transition to NCC 2022, there will be a blanket, coordinated approach permitting the use of 2019 software versions for NatHERS assessments.

Both the CSIRO and software providers have confirmed they can provide and operate NatHERS 2019 and 2022 software versions simultaneously.

Further information on this arrangement is available in this NatHERS statement.

You can visit the NatHERS software updates page for the latest information on accredited software tools, as well as how to comply with the different software versions. 

Retiring NCC 2019 software

NatHERS NCC 2019 software has been ‘retired’ in all jurisdictions that have mandated the new NCC 2022 energy efficiency requirements. 

If an assessor feels their project meets jurisdictional transition arrangements to be modelled against NCC 2019 requirements the following protocols should be followed:

  1. Get a copy of the relevant jurisdictional statement in writing (confirming 2019 software can be used).
  2. Attach the written statement to the design documents.
  3. Reference this written statement in the additional notes of the certificate.

The table below provides a list of NCC 2022 transition dates, links to building authorities and information on the NatHERS NCC 2022 software transition process. 

Contact your relevant jurisdiction for more information on the use of 2019 software.
