To minimize that waste, products can be recycled or reused. The best end of life scenario for products is reusing them, as does not consume any additional energy as they are not recycled. Another way to create less waste is to integrate renewable materials in construction solutions. Prefabricated façade solutions are a great alternative to traditional façade systems as they require less human resources and are more time-efficient on-site. This work focused on the possibility to integrate a mycelium core to sandwich panels made out of two steel facings and a PIR core. A life cycle analysis was performed on a hypothetical sandwich panel with a mycelium core and PIR sandwich panels. The feasibility of the façade leasing developed by Azcarate-Aguerre, Klein & den Heijer at TU Delft was also explored by applying this concept to a real prefabricated façade system solution. The mycelium analysis realized through an empirical method indicated that mycelium could have the mechanical properties that would allow it to be used into a sandwich panel. However, the lack of information in the literature about this material makes it unusable as a metal sandwich panel core, at the moment. The life cycle analysis showed that the production of mycelium sandwich panels had a greater impact on the environment than the production of PIR sandwich panel, which is mostly due to the drying phase of the mycelium. The LCA allowed highlighting the fact that the mycelium emits CO2, which is something that is rarely mentioned in the literature and needs to be investigated further. This work showed that the mycelium cannot be used in a sandwich panel at the moment. The application of the façade leasing concept to a real module allowed to show that it is totally achievable as long as the manufacturing and implementation process are reversible. ER -
