Exploring effective criteria for raw aluminium reduction in facade industry components: a Life Cycle Assessment approach

This paper delves into the critical realm of sustainable façade design, specifically targeting brackets and components in the tall-building industry, with a primary focus on the reduction of raw aluminium consumption within the construction sector. Employing a rigorous Life Cycle Assessment (LCA) approach, this study investigates effective criteria aimed at minimizing the environmental footprint associated with aluminium usage in façade systems, encompassing factors such as energy consumption, recyclable content, and regional transportation. Drawing upon real-life applications and case studies, including previous research conducted by the authors on the design of aluminium façade brackets, wherein a notable weight reduction of 35-45% was achieved through post-elastic properties, the potential for increased sustainability and reduced environmental impact is examined. The investigation culminates in the identification and analysis of effective criteria for reducing raw aluminium consumption, shedding light on pivotal factors such as material efficiency, recycling rates, and alternative material selection. Furthermore, through comprehensive analysis and discussion of LCA results, this paper unveils insights into the intricate interplay between aesthetic considerations and environmental sustainability in façade design. Ultimately, the findings provide valuable guidance for architects, engineers, and policymakers aiming to integrate sustainable principles into the design and construction of building façades, thereby paving the way toward greener horizons in the construction industry.
