Upscaling the use of wood products in new buildings and renovation can contribute to transform the built
environment into a large-scale carbon sink and help to unlock the low-carbon, circular economy. This case study
describes the co-design of a residential wood building in a new school complex in rural southern France. The
purpose was to maximise the use of wood in the building design, in response to green public procurement (GPP)
criteria set by the regional authority. The 4-years project was carried out by a large consortium of research
centres, architects, engineers, manufacturers, construction companies and public bodies.
A series of innovative wood-based products and system solutions were designed, tested, and manufactured for
integration in the building, including: i) a main industrial prefabricated glulam structural timber, ii) a façade system
using biocomposite profiles, and iii) a structural insulation panel for roof components and interior partitions.
Additional innovations included: iv) a pulp-based insulation foam, v) thermoplastic composite materials, and
vi) coatings with less harmful biobased agents. A digital twin model of the value chain was developed and LCA
addressed the environmental benefits. The NEB Compass assessment of the co-design highlights the role of the
coordination team to steer all phases, including the formal approval procedures of innovative solutions for use in
the public building. Thorough planning and follow-up with all parties was essential to ensure that all components
fulfilled the required performance levels and could be correctly installed by the contractor. The transdisciplinary
team made it possible to address all technical, budgetary, and managerial challenges of the complex design and
construction process. The final demo building represents a successful showcase for the New European Bauhaus
(NEB) movement on how wood innovation can bring together all relevant stakeholders to co-create beautiful,
sustainable, and inclusive solutions for the big green transformation (European_Commission, 2023).
