Innovative Timber Upcycling: Digital Strategies for Prolonging Timber Lifespan and Promoting Reuse.

Abstract This paper explores the intersection of digital and ecological transitions, crucial for achieving the European Green Deal’s sustainability targets. The construction sector, traditionally reliant on a linear “take-make-dispose” model, is gradually integrating timber, favored for its lower environmental impact compared to steel and concrete. Our research enhances the reuse of timber from demolition sites, leveraging digital technologies to extend the lifespan of timber elements and improve its carbon sequestration capabilities. This research is part of a broader initiative, the DeDa research, at the School of Architecture and Design, University of Camerino, focusing on sustainable material management in post-disaster areas. These areas, seen as ‘material banks,’ pose unique challenges due to the abundance of materials that are difficult to manage. The research comprises three integrated phases: establishing a digital material bank of timber elements, design optimization with available elements and their automated assembly. This system is underpinned by an ecosystem of digital technologies, including photogrammetric surveying, computational design, and robotic manufacturing. Considering the currently low technological level of conventional building processes, this work maintains a highly experimental character. However, presenting this research provides an opportunity to explore how digital technologies might promote circular-based building processes and encourage a shift in perspective and practices within the building industry.
