Low-carbon construction is expected to grow significantly in the future. This offers a significant opportunity for forest-dominated South Savo to strengthen expertise in the field, specialised research and development, and to promote new business based on sustainable and innovative utilisation of materials. One important opportunity to promote low carbon is to use wood in construction. In addition to wood, various composite materials such as the innovative joint use of wood, concrete and steel in large-scale construction create new testing and innovation needs. The project designs and implements a test infrastructure for the physical and environmental testing of large-scale wood and composite structures as part of the Xamk development activities of the Southeastern Finland University of Applied Sciences as part of the Savonlinna Technology Park. The equipment is widely used by industry, research and higher education. As a result of the project, regional expertise and technical infrastructure will be strengthened. Provincial actors play an important role in exploiting the future potential of low-carbon construction in Europe. In cooperation with the companies involved in the project, pilot testing of demanding wooden structures will be carried out with the equipment developed.
