Assessing Circularity Initiatives for Lowering Embodied Carbon in Australian Houses
摘要
As the global focus intensifies on emissions reduction and transitioning towards a circular economy, it becomes essential for housing practices to adapt, integrating considerations for long-term environmental sustainability. However, within the housing context, research on this critical subject remains sparse. This study represents an effort to explore the impacts of practical, context-specific circularity solutions aimed at reducing embodied carbon emissions in housing projects, based on real-life data from a case project in Australia, a common residential house. The methods involve the creation of a base building using Carbon Designer 3D from One Click LCA and analyzing it based on Life Cycle Assessment (LCA). Findings illuminate the effects of various context-specific viable circularity approaches and establish their potential to mitigate emissions. Findings show that targeting individual materials with sporadic ‘R’ imperatives reduces embodied carbon by 1–6%, while combined scenarios of C1, C2, and C3 applying multiple ‘R’ imperatives achieve reductions up to 39%. This indicates that a comprehensive and multifaceted approach to circular economy principles is essential to achieve significant reductions in emissions in typical Australian housing projects.
