Global Policy Review on Embodied Flows: Recommendations for Australian Construction Sector

Abstract

There has been a call for the construction industry to become more energy efficient in its planning and activities, to reduce greenhouse gas emissions to help combat climate change. The Australian Building Codes Board has implemented ‘Energy Efficiency’ standards through the National Construction Codes to direct the industry towards net zero emissions goals. However, the Board has maintained a focus on operational flows considerations despite this only being a part of the total expenditure in a building lifecycle. Embodied flows, the energy output, and emissions from harvesting, manufacturing, transporting, and manufacturing materials for a building have not been included as a part of the current standards despite their growing share in the outputs of construction. A qualitative document analysis using data from academic articles and industry publications was performed to identify the context in embodied policy development. Findings reveal an abundance of different legislations and initiatives globally, recommending techniques that may effectively achieve embodied flow reductions. The results highlighted that Australia needs to capitalize on the potential reductions in overall energy and emissions from construction. Other regions have provided a strategic and legislative basis for the industry to emulate.
