Further Development, Holistic Evaluation and Monitoring of “Hybrid Wood – Natural Fibre Composite Building System”

Further Development, Holistic Evaluation and Monitoring of “Hybrid Wood – Natural Fibre Composite Building System” – 2nd Phase

The “HNFVBauSys” feasibility study resulted in the development of a novel construction system, which for the first time integrates natural fibre systems and timber elements into a hybrid building system. The proposed project builds upon this foundation, with the objective of further developing the building system and investigating its application in a broad spectrum of contexts within Baden-Württemberg, Germany. In the current research project, the performance of the HNFVBauSys is being tested using an initial implementation in the form of a pavilion for the Landesgartenschau in Wangen im Allgäu.

The components consist of a combination of wooden elements and coreless wound natural fibre composite elements, which significantly reduce the material consumption and the dead weight of the components. The structural and design optimisation enables the efficient use of fibre composite and wood. Integrated fibre-optic sensors are employed to analyse force ratios and force distribution within the components. Furthermore, the life cycle assessment (LCA) of the construction project is determined, taking into account potential subsequent uses or end-of-life scenarios, and compared with conventional construction systems.

The data is analysed in order to extract findings and causal relationships, which are then implemented in existing methods and workflows. The development of a database of the fibre crop sector in Baden-Württemberg and the expansion of the bioeconomy sector model BIORESEM will enable a holistic evaluation of the potential expansion of the HNFV construction method. Interdisciplinary scenarios will be implemented in the model to determine the effects of an increased demand for fibre plants from the construction sector on agricultural markets, food security and land use in Baden-Württemberg.

In conclusion, the project contributes to the further development of the HNFV-BauSys and its application as an HNFV construction method in a broad spectrum. The results provide important insights for the construction industry and make a significant contribution to sustainability and efficiency in the construction sector.
