Trajectory for Low Energy Buildings

Publication date: Friday, 22nd November 2019.

On 1 February 2019 Energy Ministers agreed the Trajectory for Low Energy Buildings, a national plan that sets a trajectory towards zero energy (and carbon) ready buildings for Australia.

The Trajectory identifies opportunities for the building sector in the context of a broader trajectory for the sector, and in summary proposes:

  • Setting a trajectory towards zero energy (and carbon) ready buildings
  • Implementing cost effective increases to the energy efficiency provisions in the National Construction Code (NCC) for residential and commercial buildings from 2022
  • Considering options for improving existing buildings in late 2019.

The Trajectory, and its underlying reports, seek to inform the future activities of the Building Ministers' Forum and the Australian Building Codes Board when developing and implementing updates to the NCC, and to inform further Energy Council activities around building policy measures.


On 22 November 2019 Energy Ministers agreed to the Addendum to the Trajectory for Low Energy Buildings – Existing Buildings.

The Trajectory Addendum is the second stage of the national plan for a trajectory towards zero energy (and carbon) ready buildings for Australia. It provides a suite of initiatives to improve the energy efficiency of existing buildings in Australia, and in summary proposes:

  • Developing information, training and energy rating tools for households and businesses to enable greater understanding of energy efficiency options and applications.
  • Developing and expanding targeted building policies, including disclosure of energy performance, minimum energy efficiency standards for rental properties, renovations and refurbishments, improving heating, ventilation and cooling, and energy productivity in government operations.
  • Identifying and developing supporting measures, including specific measures for strata titled buildings, financial initiatives, appliance standards and labelling, specific measures for vulnerable households, a national dataset and collection process for existing homes, and other targeted initiatives.

The Trajectory and the Trajectory Addendum were developed closely with stakeholders to outline policies that deliver cost effective energy efficiency improvements to homes and businesses that lower energy bills, improve comfort and reduce pressure on the electricity grid.


On 28 October 2020, Common Capital Pty Ltd prepared advice on Financial Incentives for Energy Efficiency Upgrades to Existing Commercial Buildings. This report was commissioned by the Commonwealth on behalf of all States and Territories.

• The report presents the findings of research and analysis undertaken to support the Trajectory Addendum commitment to investigate government provision of financial incentives.

• The report proposes a set of policy options to help businesses transition to greater energy efficiency, focusing primarily on the energy use of existing commercial buildings, specifically office, retail, hotel, aged care, and warehouse buildings.
