- Biomaterials represent a potential means for the construction industry to reduce its negative ecological impact. These materials require substantially different approaches from conventional construction materials to maximise their potential. In this paper we have outlined four principles of biological design that we argue are central for the successful implementation of a new construction paradigm through biodesign. These principles are: Diversity, complexity and specificity (of form), durability through resilience, and feedback and adaptation. Diversity of material is necessary to maintain the sustainability of biomaterials when scaled up to construction industry volumes. Complexity and specificity of form enable high performativity of the built environments when using low-impact materials. Durability through resilience allows designers to work with materials that would otherwise be considered too weak. Finally, feedback and adaptation are core principles of biological design that allow plants and animals to constantly evolve in response to changing conditions, across multiple time scales, and to manage design in complex systems. In conclusion we have argued that many of these principles are found in vernacular architectural traditions, but that emerging design and fabrication technologies can enable broader implementation that can combine the benefits of modern and vernacular buildings practice.

- Biological design is able to achieve remarkable functionality, resilience and adaptability without relying on centralized coordination or resource-intense materials. Agent based construction seeks to emulate these advantages, but the two common approaches - swarm robotics and fully virtual agent simulations - are held back by limitations that are difficult to overcome in isolation. Here we demonstrate initial steps towards the application of biological design principles, particularly the so called Bernard Machine. 3D printing is used to materialize the actions of virtual agents in a physical environment. Such an arena requires a shift from monolithic printing processes to interactive ones: assemblage printing. We demonstrate an alternative to conventional slicer-controlled printing that is discrete and to an extent nonsequential and which forms the foundation for assemblage printing. In its extension it allows for the exploration of a fully agent based construction process.

Termite-inspired metamaterials for flow-active building envelopes
- 2023

Ingår i: Frontiers in Materials. - 2296-8016. ; 10

Tidskriftsartikel (refereegranskat)abstract
- In this article we investigate the performative potential of reticulated tunnel networks to act as drivers for selective airflows in building envelopes and thereby facilitate semi-passive climate regulation. We explore whether such transient flow can be used to create functionally graded metamaterials in bio-inspired, additively fabricated buildings. The tunnel networks are modelled on the egress complex found in the mound of certain macrotermite species. The hypothesis we explore is that oscillating airflow of low amplitude can be used to generate large scale turbulence within the network and thereby increase the mass transfer rates across the network. The hypothesis is tested through a series of 3-dimensional and 2-dimensional experiments where various geometries are exposed to a forced oscillation of the air or water column. The results are evaluated in the 3-dimesional experiments through tracer gas measurements, and in the 2-dimenstional experiments through visual qualitative assessment using fluorescein dye. We find that the oscillating fluid gives rise to large scale turbulence that causes a net mass transport across the tunnel network, and that this turbulence occurs when certain combinations of amplitude, frequency, and network geometry are achieved. Furthermore, we conclude that the net mass transfer is large enough to be functionally useful in a building envelope as a method to regulate either building interior climate or the envelope’s own microclimate.

- Meristem Wall is a prototype for a 3D-printed building envelope, featuring a dynamically controllable network of integrated air channels that allow a fl uid and adaptive relationship between inside and outside. The wall integrates functional lighting and electricity, windows, and a custom CNC-knitted textile interior. It is fabricated through binder-jet sand 3D printing and points towards a climatically performative architecture inclusive of nonhuman life in urban contexts.

Transcalar Design : An Approach to Biodesign in the Built Environment

Tidskriftsartikel (refereegranskat)abstract
- Biodesign holds the potential for radically increasing the sustainability of the built environment and our material culture but comes with new challenges. One of these is the bridging of the vast differences of scale between microbiological processes and architecture. We propose that a transcalar design approach, which weaves together nonlinear dependencies using computational design tools and design methodologies through the biological generation of architectural components, is a way towards successful design implementations. Such design processes were explored in a laboratory-based fabrication and study of a column element. This column, named Protomycokion, serves to illustrate how design methodologies, particularly through the use of a demonstrator artefact, can serve to navigate the multiple scales, disciplines, and experiments that are necessary to engage the complexities of biodesign. Transcalar design processes embrace the adaptability, variability and inter-dependence of biological organisms and show possible gains with regard to material sustainability and increased performativity.
