Abstract :
[en] The evolving landscape of environmental and economic challenges in the construction sector underscores the
need for innovative material solutions. Wood is increasingly considered a viable alternative, offering a potential
path forward. With its renewable nature, carbon sequestration potential, and favourable mechanical properties
for its relatively low weight, wood differentiates itself from conventional materials. However, environmental
crises and evolving climate conditions threaten the long-term stability of wood resources, underscoring the need
for proactive and diversified strategies in resource management. To address these challenges, this study presents
TUP4C (Timber Utilisation Potential for Construction), a decision-support approach designed to assist multiple
stakeholders in selecting suitable wood species for construction. The tool integrates economic, environmental,
social and technical criteria within a holistic, multi-criteria decision-making framework. Its adaptable design
allows for customisation to various stakeholder profiles, aligning with their priorities, targeted product categories,
and strategic timeframes. In the preliminary phase of a project, the tool reveals diversification opportunities
by considering new wood species aligned with a defined product and vision. An application in Wallonia
(Belgium) demonstrates its ability to highlight lesser-known hardwoods while confirming spruce’s industrial
predominance for structural and exterior joinery applications. By promoting the use of diversified wood species,
TUP4C contributes to a more resilient and adaptive forestry-wood-construction sector, fostering sustainable
resource management and strategic decision-making.
