In 2018-2019, the former COAG Energy Council provided funding to pilot a national version of the Victorian Residential Efficiency Scorecard (Scorecard) tool in capital cities (Adelaide, Brisbane, Canberra, Hobart, Perth and Sydney). 

A customised version of the Scorecard was developed for tropical climate zones across northern Australia. It was adjusted to include key features that are important to tropical housing design, such as ventilation, shading, roof colour and ceiling fans.

The Report for Achieving Low Energy Existing Homes sets out practical options that informed the Trajectory Addendum for achieving zero energy (and carbon) ready existing homes.

The Addendum to the Trajectory for Low Energy Buildings—Existing Buildings is the former COAG Energy Council-agreed workstream to take existing buildings to being net zero energy ready.

The International Partnership for Energy Efficiency Cooperation (IPEEC) has 10 task groups, which includes the Buildings Energy Efficiency Taskgroup (BEET) co-chaired by Australia and the USA. BEET is a collaborative platform for countries to research, inform and support the development and implementation of effective building energy efficiency policies, with a core focus on building rating systems and building codes.

The ‘Achieving Low Energy Existing Commercial Buildings in Australia’ Report was commissioned to consider policy options for the COAG Energy Council’s Trajectory for Low Energy Buildings.
