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:

NCC 2019 Energy Efficiency

This project stems from Measure 31 of Council of Australian Government’s National Energy Productivity Plan, where the ABCB has been requested to consider changes to the energy efficiency provisions for NCC 2019.

For commercial buildings (common areas of Class 2 buildings, Class 3 buildings and Class 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 buildings, the sole-occupancy units of Class 2 buildings and a Class 4 part of a building), the ABCB is to establish a foundation for a possible future stringency increase, as well as making improvements to facilitate greater compliance.

More details are available on the NCC 2019 Energy Efficiency Project; including the stakeholders involved, relevant resources and project news.

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.

In the meantime, there is guidance materials available to assist with minimising condensation in buildings.
