Pathways Towards Life Cycle Net-Zero Emissions in Australian Residential Buildings

The residential building sector is responsible for substantial amounts of energy use and greenhouse gas (GHG) emissions in Australia. To support a net-zero built environment, it is critical to evaluate both energy and financial requirements of energy-saving solutions and provide effective strategies for stakeholders of the built environment. The specific objectives of this project are: (a) identify and summarise the energy reduction strategies for residential buildings; (b) conduct a comprehensive life cycle energy and cost analysis of these strategies; and (c) provide the energy-efficient and cost-effective strategies for various decision-makers (e.g., building designers, contractors, occupants, urban planners, and policymakers). The expected outcomes will include detailed insights into the effectiveness of different energy reduction measures, balancing both environmental and economic considerations. This research will provide pathways to help Australian Residential buildings to achieve the life cycle net-zero emissions.
