“…This will be achieved by minimizing life cycle impacts and capturing and disposing of emission rates [8]. 4 The proto-typological design of the green responsive system Heisel and Hebel introduce the concept of proto-typology [9], a significant paradigm shift in the use and innovation of construction materials. This term, a blend of "prototype" and "typology," signifies the application of full-scale models to enhance sustainability and resource efficiency in construction.…”

In being aware of certain factors as the increasing of the pollution levels, the effects of the Urban Heat Island, or all the extreme climate events attributable to the constant increasing of CO2 emissions. This paper intends to propose an innovative approach to design systems and components that allow to adapt the built environment and mitigate the effects of the Climate Change in the urban Mediterranean areas. An experimental investigation at the building scale was conducted to study the environmental aspects in the early design phase that incorporate circular and ecological materials. The physical interactions between the built and the natural environment is enhanced with the upcycling design of the “Liminal Space” through the prototypological model for the “Green Responsive System”. The focus on the LS needs to push the technological definition beyond the concept of building envelope, just as the element of internal/external separation. The LS is where the “Advanced Circular Design” model can improve with the design of the GRS all the technological elements of adiabatic nature. The proposed framework enables the GRS to have a dynamic and systemic answer to the extreme change of the climatic situation in order to have a strong impact on the performance related to the environmental aspects. The parametric tools in the ACD model offers an important digital interface that can include all the regenerative requirements of the entire building considering the embodied CO2 emissions, the production and the energy consumption during the operational phase, and at the same time to control and improve the recyclability of all its components. The structure of the paper is presented as a succession of digital and physical design processes that identify all the phases for the definition of the GRS when it works on the LS. This becomes a central node in the development of the methodological framework for the upcycling design and the digital control of the responsiveness in the technological systems used for the integration of the physical aspects and the digital devices by using circular materials.

“…The most common approach has been to create mycelium building blocks that are assembled into larger structures. However, this application often relies on substructures, and is geometrically quite limiting due to the inherent properties of mycelium that only allows for structures in compression [ 7 , 16 ]. Studies have also been carried out on monolithic mycelium constructions, but these systems require either large scaffolds or extensive reinforcement systems that in most cases take over the structural functions and reduce the mycelium to a surface finishing, rather than a load-bearing material [ 17 ].…”

The demand for building materials has been constantly increasing, which leads to excessive energy consumption for their provision. The looming environmental consequences have triggered the search for sustainable alternatives. Mycelium, as a rapidly renewable, low-carbon natural material that can withstand compressive forces and has inherent acoustic and fire-resistance properties, could be a potential solution to this problem. However, due to its low tensile, flexural and shear strength, mycelium is not currently widely used commercially in the construction industry. Therefore, this research focuses on improving the structural performance of mycelium composites for interior use through custom robotic additive manufacturing processes that integrate continuous wood fibers into the mycelial matrix as reinforcement. This creates a novel, 100% bio-based, wood-veneer-reinforced mycelium composite. As base materials, Ganoderma lucidum and hemp hurds for mycelium growth and maple veneer for reinforcement were pre-selected for this study. Compression, pull-out, and three-point bending tests comparing the unreinforced samples to the veneer-reinforced samples were performed, revealing improvements on the bending resistance of the reinforced samples. Additionally, the tensile strength of the reinforcement joints was examined and proved to be stronger than the material itself. The paper presents preliminary experiment results showing the effect of veneer reinforcements on increasing bending resistance, discusses the potential benefits of combining wood veneer and mycelium’s distinct material properties, and highlights methods for the design and production of architectural components.

“…Thus, the structure can bear the load without sub-structures. In 2019, Mycotree 2.0, a smaller structure made with the same material and technique, was shown in Shaping the Future exhibition in Berlin (Heisel and Hebel 2019). Regarding the complexity of the components, Mycotree is an exemplary project.…”

Mycelium-based composites (MBC) are biomaterials presenting renewable and bio-degradable alternatives for a wide range of design and manufacturing processes, including the building industry. MBC result from the incomplete growth of mycelium, fibrous root systems of fungi. They can turn urban and agricultural waste into high-end products. Existing research shows that MBC can reduce fossil fuels’ reliance and embodied energy and decrease building waste. Architects recently designed and built a wide range of experimental projects with MBC. In parallel, there is a growing body of work on MBC by scholars from different disciplines, such as mycology, material science, and mechanical engineering, focusing on assessing and enhancing the material properties of MBC for various applications. In this paper, we first provide essential knowledge on the cultivation of MBC for architectural applications. Next, we analyze some of the prominent architectural prototypes with MBC to exemplify the architectural potentials of MBC and uncover the constraints and affordances of this biomaterial when used in an architectural context. Finally, we review and synthesize the existing literature on MBC from different disciplines providing a guide for architects to cultivate and enhance the material properties of MBC for architectural goals.
