The Zero Carbon Australia (ZCA) Buildings Plan demonstrates that there are no technical barriers to zero emissions buildings in Australia. This is achieved through a planned energy efficiency retrofit of the existing building stock onsite renewable energy generation, and electrifying current gas appliances. (For an explanation of why we’re recommending the removal discontinuation of the use of gas, please see our fact sheet)
This report does not aim to make individual buildings energy self-sufficient (i.e. zero net energy consumption) as each building is planned to be connect to a 100% renewable energy grid as outlined in the ZCA Stationary Energy Plan. However, it identifies the maximum feasible contribution from distributed onsite electricity generation using solar photovoltaic technology and some small wind turbines.
The Buildings Plan comprises of the following components:
- The most comprehensive compilation and assessment of all categories of Australia’s existing building stock across all climate zones.
- Review of multiple case studies of successful building retrofits and characterise energy savings, cost and efficacy of each method applied.
- Review and judgement of commercially available technologies and methods for achieving energy efficiencies and for onsite heat and electricity generation.
- Proposed viable blueprint for energy efficient retrofits on each building sub-category in each climate zone.
- Quantification of required resources to implement plan and capacity to roll out process, including timeline.
- Estimated investment costs and expected savings from implementing the Buildings Plan.
The report is a collaboration between individuals, relevant businesses, industry bodies, all levels of government, and academic institutions to draw upon existing knowledge, experience, research, and data. The ZCA Buildings Plan has, to date, received generous support from over 80 volunteers. It was also received pro-bono assistance from a range of organisations and companies including: WSP Built Ecology; Energy Efficient Strategies; Sustainability Victoria; Entura; GHD; Melbourne University’s Department of Building, Planning and Architecture; Solem Consulting; Investa; and VIPAC, just to name a few.
