Perspective Chapter: Expert Opinions on Data-Driven LCA-Based Frameworks for Modular Façade Systems

This study explores the potential, challenges, and perspectives of data-driven frameworks to enhance environmental impact assessment and promote circular economy practices across the life cycle of modular façade systems. Building on prior research and innovation efforts in the field, semi-structured interviews were conducted with stakeholders representing diverse backgrounds to ensure a wide range of perspectives, including health, safety, and environment (HSE) managers, façade engineers, and software developers. The methodology was organised into three main phases. It began with a preparation phase, followed by the conduct of interviews. During these interviews, previous research findings were presented, leading to a discussion centred on the perceived potential, challenges, and perspectives related to these technologies. Finally, a thematic analysis was conducted to identify the common insights that emerged. The findings emphasise the importance of standardised data models, interoperability between systems, and the role of value chain networking and collaboration in advancing circular economy practices. While not exhaustive, the study provides valuable insights into the evolving landscape of sustainable façade construction and offers recommendations for future developments in LCA-based Frameworks for circular economy integration.
