The Australian Building Codes Board (ABCB) is seeking comment on proposed amendments to energy efficiency and condensation technical provisions, for possible inclusion in National Construction Code (NCC) 2022.

To help reduce the burden on stakeholders, feedback on NCC 2022 is being sought via two separate consultation stages. Stage 1 was held between 10 May and 11 July 2021 and is now closed.

Some of the more significant amendments proposed in this second and final stage of consultation include a stringency increase in the thermal performance of homes from the current level, equivalent to 6-stars NatHERS, to the equivalent of 7 stars.

Another amendment is enhanced condensation management provisions, including additional ventilation and wall vapour permeability requirements.

There is also a new provision designed to allow easy retrofit of on-site renewables and electric vehicle charging equipment for class two to class nine buildings.

Consultation ends 17 October, 2021 and the final RIS will be publicly released mid-2022.
