RESOURCE-EFFICIENT AND CIRCULAR TIMBER BUILDING SYSTEM FOR NEW CONSTRUCTION AND EXISTING BUILDING STOCK EXTENSION
The project advances the multi-storey timber building system developed in the first funding period of the IntCDC Cluster of Excellence towards circularity, material agency, and regional specificity by integrating secondary timber. In the context of this research, secondary timber refers to all wood resources that are currently not utilised for engineered wood products and are usually not addressed within existing building codes and normative frameworks. This includes damaged timber, fabrication offcuts, reused and reclaimed timber, a wider range of wood species, and consideration of low-grade structural wood across all the above-mentioned categories. The project focuses on developing feature-specific assessment, design and engineering methods, and on enabling variable base materials to reduce emissions and extend the life cycle of existing timber resources. At the same time, extending the design space of timber structures through adaptive design and engineering methods for resilient timber architecture remains a key goal.
