In late 2018 the Council of Australian Governments (COAG) Energy Council will consider a trajectory for low energy homes, including potential energy efficiency changes for the 2022 update of the NCC. The Trajectory is a collaborative project of the Commonwealth, State and Territory Governments.
Should the COAG Energy Council agree to NCC changes, the Building Ministers Forum (BMF) will be asked to task the ABCB with implementing potential changes through its NCC 2022 update process, including conducting a Regulatory Impact Statement (RIS).
On 27 April 2018 the Building Ministers Forum announced that the ABCB 2018-19 work plan will include the development of energy efficiency measures for residential buildings.
The Trajectory for Low Energy Homes forms part of Measure 31 of the COAG Energy Council’s National Energy Productivity Plan 2015-2030 (NEPP). The NEPP provides a framework and an initial economy-wide work plan designed to accelerate action to deliver a 40% improvement in Australia’s energy productivity by 2030.
Stage 1 and 2 of the Trajectory involved a research project in collaboration with AECOM, which considered a ‘whole of house’ approach to achieving net zero energy/carbon buildings for new and existing dwellings. The research project analysed existing residential building typologies (built form, appliances and energy use) and new residential building stocks in each jurisdiction, using modelling by the CSIRO developed AusZEH software. This work found that zero energy/carbon detached homes are cost effective to build today, while further consideration is needed on cost effectively lowering apartment energy usage.
Stage 3 of the Trajectory is now using this analysis to inform more detailed policy development and cost benefit analysis, to develop a trajectory for future residential building energy efficiency reforms, including potentially through the NCC.
A Stakeholder Reference Group (SRG), with over 170 participants, has been established to inform the Trajectory. The SRG has met regularly since December 2017 via teleconferences and workshops in Canberra, Sydney and Melbourne. The next SRG workshops will be held in July.
