Energy Efficiency

Energy efficiency is currently a core focus of the ABCB, with a variety of initiatives related to updating the NCC energy efficiency requirements in 2019. Some of these initiatives include:

Energy Efficiency for NCC 2019

Under Measure 31 of Council of Australian Government’s National Energy Productivity Plan (NEPP), the ABCB has been requested to consider changes to the energy efficiency provisions for NCC 2019. For commercial buildings (Class 3 and 5 to 9 buildings), consideration is to be given to an economically feasible stringency increase and other improvements to facilitate greater compliance.

For residential buildings (Class 1, 2 and 4 buildings), the ABCB is to establish a foundation for a possible future stringency increase, as well as making improvements to facilitate greater compliance.

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.  Consideration will be given to potential changes for NCC 2019 and/or supporting guidance material.
