Consultation is open for the ABCB energy efficiency scoping study and new materials are now available for download to support the NCC Volume One energy efficiency provisions.

NCC 2022 and beyond… Scoping study

Public consultation is currently open for the energy efficiency scoping study. The ABCB has released the Energy Efficiency – NCC 2022 and beyond scoping study to seek initial views on the proposed approach and scope of the NCC energy efficiency provisions, with a focus on residential buildings in NCC 2022.

This work will be carried out in consideration of the Council of Australian Governments (COAG) Energy Council’s Trajectory for Low Energy Buildings (The Trajectory), which proposes incremental changes to the NCC to reduce the operational energy use and associated greenhouse gas emissions of buildings.

Providing comment

Responses to questions on the scoping study, outlined in the consultation form, are invited until 11.59pm AEST Sunday 8 September 2019. Only comments submitted using the online form will be considered.

Volume One handbook

This non-mandatory handbook provides information to support the energy efficiency provisions in Volume One of NCC 2019. It aims to provide practitioners with sufficient knowledge to successfully apply the energy efficiency provisions for multi-residential, commercial and public buildings.

The handbook has a practical focus, and is intended to provide an understanding of the policy objectives and the technical basis of the NCC provisions. This will assist practitioners in dealing with a range of situations where different design and assessment tools are needed.


A suite of four Volume One energy efficiency calculators have been released for beta testing. The calculators assist users with understanding and applying the NCC’s Volume One Deemed-to-Satisfy (DTS) energy efficiency provisions for facades, fans, pumps and lighting.

NCC Volume Two calculators for residential energy efficiency are currently undergoing minor changes to align with NCC 2019 and will be released shortly. These calculators will retain their functionality, but will have a fresh look and feel.

Providing feedback

Users are invited to provide feedback on the beta testing calculators by submitting an online enquiry. Feedback is open until Sunday 3 November 2019.

Additional support

Additional supporting materials for the new Volume One energy efficiency provisions will be released soon. Ensure that you have registered your interest in commercial energy efficiency for notification of their availability.
