Circular by nature: Framing the need for design for circularity in mass timber structures

Abstract

Circular construction is increasingly touted as a more sustainable approach aimed at decoupling construction activities from the depletion of virgin materials and minimizing the environmental impact of the construction industry. To support this, numerous design strategies have been developed under the collective term 'Design for Circularity' (DfC). In line with circular possibilities, wood-based construction products, such as mass timber, are gaining attention in recent scientific literature. However, due to its novelty, the full benefits of integrating MTS within DfC remain little explored. To address this gap, the present study aimed to conduct a comprehensive analysis, mapping the benefits of DfC and exploring its significance for MTS. A narrative review was employed as the methodological approach to achieve the research objectives. The study provides an integrative overview that bridges environmental, economic, and social perspectives. This analysis advances academic discourse through a critical evaluation. Adopting this holistic perspective can prevent misunderstandings and misapplications of the concept, which could otherwise result in unintended consequences, such as a false sense of effectiveness. Recognizing these interconnections promotes a more thoughtful approach to circularity, comprehensively considering the building's complex relationships with the environment, the economy, and society.
