Energy efficiency is a core focus of the ABCB and forms part of the Australian, state and territory governments’ strategies to improve energy productivity and reduce greenhouse gas emissions.

NCC 2022 Energy Efficiency

This project was initiated by the Council of Australian Governments (COAG) Energy Council’s National Energy Productivity Plan and Trajectory for Low Energy Buildings.

After focussing on commercial building energy efficiency in NCC 2019, the emphasis of the NCC 2022 energy efficiency work will be on residential buildings. This will involve the development of enhanced energy efficiency provisions for residential buildings, including a possible increase in the level of thermal comfort and a whole-of-house-energy use budget. For commercial buildings, initial investigations will be carried out to support possible future changes in NCC 2025.

A scoping study, titled Energy Efficiency Scoping Study: NCC 2022 and beyond, was released for public comment in August/September 2019 to seek initial views on the proposed approach and scope of future changes to the NCC energy efficiency provisions particularly in 2022.

The below table lists energy efficiency resources. 

Condensation in Buildings

This project involves investigating the role of the NCC in mitigating the risk of condensation in residential buildings. It is being carried out in response to feedback from industry and building regulators. After introducing initial condensation provisions in NCC 2019, consideration will be given to further opportunities for addressing the risk of condensation. This work will be undertaken in conjunction with the energy efficiency changes for residential buildings planned for NCC 2022.

Updated guidance material is also available to assist with minimising condensation in buildings.
