Trajectory for low energy homes

Australian governments are advancing the energy performance of residential and commercial buildings through the development of a Trajectory for Low Energy Buildings (the Trajectory). The Trajectory identifies cost effective opportunities for energy efficiency improvements throughout the building system, from thermal performance to appliance energy usage and potentially renewable energy generation.

Cost effective improvements to Australia’s building stock could significantly improve Australia’s energy productivity and reduce running costs for consumers. Preliminary analysis indicates that changes to the NCC in 2022 could deliver household bill savings of over $650 each year in colder or tropical climates, such as Canberra, Townsville and Darwin, and around $170 each year in temperate climates, such as Sydney, Melbourne and Adelaide.

The Trajectory has been developed cooperatively between Commonwealth, State and Territory Governments, and through extensive consultations with representatives from a range of sectors including: building and property, appliance and technology, energy supply and distribution, environmental, energy consumers, energy efficiency, and academia.

The proposed Trajectory and changes to the NCC in 2022 are expected to be considered by the COAG Energy Council in December 2018. If agreed, approval will then be sought from the Building Ministers’ Forum in early 2019 for the ABCB to commence a formal NCC change process.
