title	Additive Manufacture of Cellulose Based Bio-Material on Architectural Scale
source	Proceedings of the 2021 DigitalFUTURES The 3rd International Conference on Computational Design and Robotic Fabrication (CDRF 2021)

summary	There are severe environmental and ecological issues once we evaluate the architecture industry with LCA (Life Cycle Assessment), such as emission of CO2 caused by necessary high temperature for producing cement and significant amounts of Construction Demolition Waste (CDW) in deteriorated and obsolete buildings. One of the ways to solve these problems is Bio-Material. CELLULOSE and CHITON is the 1st and 2nd abundant substance in nature (Duro-Royo, J.: Aguahoja_ProgrammableWater-based Biocomposites for Digital Design and Fabrication across Scales. MIT, pp. 1–3 (2019)), which means significantly potential for architectural dimension production. Meanwhile, renewability and biodegradability make it more conducive to the current problem of construction pollution. The purpose of this study is to explore Cellulose Based Biomaterial and bring it into architectural scale additive manufacture that engages with performance in the material development, with respect to time of solidification and control of shrinkage, as well as offering mechanical strength. At present, the experiments have proved the possibility of developing a cellulose-chitosan- based composite into 3D-Printing Construction Material (Sanandiya, N.D., Vijay, Y., Dimopoulou, M., Dritsas, S., Fernandez, J.G.: Large-scale additive manufacturing with bioinspired cellulosic materials. Sci. Rep. 8(1), 1–5 (2018)). Moreover, The research shows that the characteristics (Such as waterproof, bending, compression, tensile, transparency) of the composite can be enhanced by different additives (such as xanthan gum, paper fiber, flour), which means it can be customized into various architectural components based on Performance Directional Optimization. This solution has a positive effect on environmental impact reduction and is of great significance in putting the architectural construction industry into a more environment-friendly and smart state.

summary	This project emerged from collaborative trans-disciplinary research between architecture, engineering, biology, and materials science to generate novel applications in micro-scale 3D printed ceramics. Specifically, PolyBrick H2.0 adapts internal bone-based hydraulic networks through controlled water flow from 3D printed micro-textures and surface chemistry. Engagement across disciplines produced the PolyBrick series at the Sabin Lab (Sabin, Miller, and Cassab 2014) . The series is a manifestation of novel digital fabrication techniques, bioinspired design, materials inquiry, and contemporary evolutions of building materials. A new purpose for the brick is explored that is not solely focused on the mechanical constraints necessary for built masonry structures. PolyBrick H2.0 interweaves the intricacies of living systems (beings and environments combined) to create a more responsive and interactive material system. The PolyBrick 2.0 series looks at human bone as a design model for foundational research. PolyBrick H2.0 merges the cortical bone hydraulic network with new functionalities as a water filtration and collection system for self-preservation and conservation as well as passive cooling solutions. It also pushes the ability of 3D printing techniques to the microscale. These functionalities are investigated under context for a better construction material, but its use may extend further.

title	Unprintable Forms
source	ACADIA 19:UBIQUITY AND AUTONOMY [Proceedings of the 39th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-59179-7] (The University of Texas at Austin School of Architecture, Austin, Texas 21-26 October, 2019) pp.168-177

summary	This paper presents a 3D Concrete Printing (3DCP) experiment at the full scale of virtualarchitectural bodies developed through a computational technique based on the use of Cellular Automata (CA). The theoretical concept behind this technique is the decoding of errors in form generation and the invention of a process that would recreate the errors as a response to optimization (Adilenidou 2015). The generative design process established a family of structural and formal elements whose proliferation is guided through sets of differential grids (multi-grids) leading to the build-up of large span structures and edifices, for example, a cathedral. This tooling system is capable of producing, with specific inputs, a large number of outcomes in different scales. However, the resulting virtual surfaces could be considered as "unprintable" either due to their need of extra support or due to the presence of many cavities in the surface topology. The above characteristics could be categorized as errors, malfunctions, or undesired details in the geometry of a form that would need to be eliminated to prepare it for printing. This research project attempts to transform these "fabrication imprecisions" through new 3DCP techniques into factors of robustness of the resulting structure. The process includes the elimination of the detail / "errors" of the surface and their later reinsertion as structural folds that would strengthen the assembly. Through this process, the tangible outputs achieved fulfill design and functional requirements without compromising their structural integrity due to the manufacturing constraints.

title	A Holistic Approach to Feature-based Structural Mapping in Cross Laminated Timber Buildings

summary	Mass Engineered Timber products provide a unique opportunity in configuring panelized building systems that are suitable for both prefabrication and onsite customization. The structural nature of these large section elements also brings about the need for a coordinated design-fabrication-assembly workflow. These products can assume different geometric configurations and their behaviour can be approximated globally by simplifying framing schemas. Current BIM Interoperability standards such as STEP or IFC already acknowledge and support the interconnected nature of component properties, yet these Data Models are component focused. Expanding on the relationships between components and using sets to define part to whole, or exteriority relationships could yield a more flexible and agile querying of building information.This would be a framework fit for automated feature derivation and rule based design applications. To this end Graph structures and Graph Databases, alongside existing ontology authoring tools are studied to probe new cognitive possibilities in collaborative AEC workflows

title	Experimental Biocomposite Pavilion

summary	Excessive use of aggregate materials and metals in construction should be balanced by increasing use of construction materials from annually renewable resources based on natural lignocellulosic fibers. Parametric design tools gave here a possibility of using an alternative newly developed biocomposite material, for realization of complex geometries. Contemporary digital fabrication tools have enabled precise manufacturing possibilities and sophisticated geometry-making to take place that helped in obtaining high structural behavior of the overall global geometry of the discussed project. This paper presents a process of realizing an experimental structure made from Natural Fiber-Reinforced Polymers (NFRP)- also referred to as biocomposites, which were synthesized from lignocellulosic flexible core reinforced by 3D-veneer layers in a closed-moulding vacuum-assisted process. The biocomposite sandwich panels parameters were developed and defined before the final properties were imbedded in the parametric model. This paper showcases the multi-disciplinarity work between architects, structural engineers and material developers. It allowed the architects to work on the material development themselves and enabled to apply a new created design philosophy by the first author, namely applying ‘Materials as a Design-Tool’. The erected biocomposite segmented shell construction allowed a 1:1 validation for the whole design process, material development and the digital fabrication processes applied. The whole development has been reached after merging an ongoing industrial research project results with academic education at the school of architecture in Stuttgart-Germany.

doi	https://doi.org/10.52842/conf.acadia.2019.140
summary	This research showcases the integrated design process and development of an ultra-light-weight, composite dome structure as a case study for the investigation of high-performance, long-span, fibre-reinforced-polymer (FRP) based building systems. Particular emphasis is given to the exploration of design strategies and the exposure of multidirectional flows of information across different fields under the premise of going beyond preliminary investigations on a demonstrator level, towards full scale architectural applications. Building upon previous research in the realm of lightweight fiber composites conducted at the University of Stuttgart, novel design strategies and fabrication methods are discussed. Based on the design and development of the Buga Fibre Pavilion for the Heilbronn Bundesgartenschau 2019, previously prototypically tested processes are further developed and implemented at a larger scale which attempt to reduce the necessary formwork to a minimum while achieving a flexible and scalable building system.

title	Blockchain Grammars - Designing with DAOs - The blockchain as a design platform for shape grammarists' decentralised collaboration
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 293-302
doi	https://doi.org/10.52842/conf.caadria.2019.2.293
summary	This paper presents an application of Decentralised Autonomous Organisation (DAO) in the field of design and AEC industry. The model is applied in the realm of shape grammar proposing the possibility of allowing multiple grammarists to collaborate in the definition of a new grammar within a Blockchain environment that acts as a distributed ledger. DAOs systems and Blockchain are introduced as well as shape grammar and its fundamental rules. The collaborative nature of a DAO with the inner logic of shape grammar, which bases its principle and rules in multiple variations and combinations of simple initial shapes, brings to the problem of recording and validating changes and improvements in the design chain. For this reason, a voting system to govern the process is introduced, based on both quantitative values, i.e. number of votes, and qualitative power, i.e. the reputation of who votes, applying a factor that scales the vote according to the expertise of the voter. An example is provided showing a possible scenario in a design environment along with validation criteria, and predicting future stages applied in an always more BIM-oriented practice.

doi	https://doi.org/10.52842/conf.ecaade.2019.2.655
summary	This paper aims to link human's emotions and cognition to the built environment to improve the user's mental health and well-being. It focuses on cyber-physical adaptive spaces that can respond to the user's physiological and psychological needs based on their biological and neurological data. Through artificial intelligence and affective computing, this paper seeks to create user-oriented spaces that can learn from occupant's behavioral patterns in real-time, reduce user's anxiety and depression, enhance environmental quality, and promote more flexible human-centered designs for people with mental/physical disabilities. To achieve its objectives, this research integrates tangible computing devices/interfaces, robotic self-adjusting structures, interactive systems of control, programmable materials, human behavior, and a sensory network. Through embedded responsiveness and material intelligence, the goal is to blur the lines between the physical, digital, and biological spheres and create cyber-physical spaces that can "feel" and be controlled by the user's mind and feelings.

title	Semi-flexible Additive Manufacturing Materials for Modularization Purposes - A modular assembly proposal for a foam edge-based spatial framework
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 463-470
doi	https://doi.org/10.52842/conf.ecaade.2019.1.463
summary	This paper introduces a series of design and fabrication tests directed towards the use of bendable 3D printing materials in order to simplify a foam bubble-based geometry as a frame structure for modular assembly. The aspiration to reference a spittlebug's bubble cocoon in nature for a light installation in the urban context was integrated into a computational workflow conditioning light-weight, material-, and cost savings along with assembly-simplicity. Firstly, before elaborating on the project motivation and background in foam structures and applications of 3D-printed thermoplastic polyurethane (TPU) material, this paper describes the physical nature of bubble foams in its relevant aspects. Subsequently this is implemented into the parametric design process for an optimized foam structure with Grasshopper clarifying the need for flexible materials to enhance modular feasibility. Following, the additive manufacturing iterations of the digitally designed node components with TPU are presented and evaluated. Finally, after the test assembly of both components is depicted, this paper assesses the divergence between natural foams and the case study structure with respect to self-organizing behavior.

doi	https://doi.org/10.52842/conf.acadia.2019.654
summary	The aim of this research is to challenge the prevalent separation between (digital) design and (physical) operation processes of adaptive and interactive architectural systems. The linearity of these processes implies predetermined material or kinetic behaviors, limiting performances to those that are predictable and safe. This is particularly restricting with regard to compliant or flexible material systems, which exhibit significant kinetic and thus adaptive potential, but behave in ways that are difficult to fully predict in advance. In this paper we present a hybrid approach: a real-time, interactive design and operation process that enables the (material) system to be self-aware, fully utilizing and exploring its kinetic design space for adaptive purposes. The proposed approach is based on the interaction of compliant materials with embedded robotic agents, at the interface between digital and physical. This is demonstrated in the form of a room-scale spatial architectural robot, comprising networks of linear elastic components augmented with robotic joints capable of sensing and two axis actuation. The system features both a physical instance and a corresponding digital twin that continuously augments physical performances based on simulation feedback informed by sensor data from the robotic joints. With this setup, spatial adaptation and reconfiguration can be designed in real-time, based on an openended and cyber-physical negotiation between numerical, robotic, material, and human behaviors, in the context of a physically deployed structure and its occupants.

doi	https://doi.org/10.52842/conf.ecaade.2019.2.837
summary	This paper presents our findings on knowledge work environment usage behaviour through a combined automated mobile indoor positioning system and self-reports collected from the environment's inhabitants. Contemporary work environments are increasingly flexible multi-occupant environments as opposed to cellular offices. Understanding persons' task-related and situation-related environmental needs is critical to improve the design of future knowledge work environments. This study is conducted in a team office environment prior to and following an intervention in which the office layout was re-organized. The combined methodological approach described in this paper provides a new tool for architecture researchers aiming to understand the use of workspaces. Importantly, combining self-reports with context-aware location data collection provides researchers an efficient in situ tool to access participants experiences and decision-making process in choosing their workstation or workspace.

summary	Most cities is becoming densely populated in unstable society. Demand for single-person households is increasing and also the demand for collective housing is increasing. In this situation, urban housing should be open and flexible and should move toward increasing opportunities for social exchange and satisfaction of resident. In this paper, development of new collective housing was explored to enable flexible and efficient communication and sharing by utilizing branch structure through Constructal theory on efficient flow in system. The methodology was proposed for future collective housing design through parametric design model with tree diagram that show the flow of shared spaces. This could be a solution to future social sustainability as a proposal to increase the shareability and respond to the demand for new building shapes.

summary	This thesis research deals with the architectural project from an interdisciplinary point of view, integrating biomimetics, additive fabrication, computer vision, and robotics. The work focuses on the feedback interaction loop among robotic additive fabrication, a stigmergic agent-based system and the self-organizing properties of the material. The aim is to explore the morphological, constructive and expressive potentials generated by the mutual influence of computational design, construction behavioral rules, and physical material behavior (whose complexity exceeds current simulation capacity).The proposed approach leads to the creation of surface-based tectonics, enhanced with a fiberglass-coated dendritic ridge formation that integrates functional, ornamental and structural performances. The process can be extended to larger architectural scales with the creation of bespoke EPS molds via robotic hot wire cutting; the presented case study leverages the aforementioned process on ruled surfaces for the generation of translucent delimiters, used to create heterogeneous spatial organization.

summary	This paper explores the use of smart technologies like physical computing with a sensor and an actuator, to create a prototype of a wearable technology, which augments our interaction with the environment, and people. The initial design idea was based on an empirical study of varying body heat signature patterns corresponding to emotions. However, we are interested to expand the discussion beyond technical issues in the design process, to reflect on the broader relationship of the human body with space and people. The study raises some important questions vis-?-vis current mobility and scalar reduction of Technology today: What is the relationship between architecture and the human body? Can a wearable technology be used to indicate, and express a fluctuating emotion? How would a traditional garment element evolve to respond to a new requirement or program? What are the appropriate scales we should refer in order to design our surrounding space? What sort of expertise is required to shift in design scales?

title	Design, Analysis and Robotic Fabrication of a Bending-Active Shell Structure with Thin Sheets Based on Curved-Crease-Folding Technique
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 1, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 63-72
doi	https://doi.org/10.52842/conf.caadria.2019.1.063
summary	This paper shows a design and building application of an innovative structure concept which is developed by the authors. The long-span shell structure (8m10m2.5m) built with 1.5mm thin aluminum sheets demonstrates the possibility to apply bending-active structures with flexible thin sheet material in shell structures to enhance the global and local stiffness. The structure is mainly originated from the curved-crease-folding technique which enhances the structural stiffness by introducing curvature to the surfaces. The Y-shape structural elements define the basic geometrical rules and find its global double-curved geometry via the folding of the three lateral ribs. The full-scale prototype and its design and fabrication techniques show a design framework of the structure from its form-finding, surface optimization, robotic simulated fabrication to the final full-scale assembly. As a pioneer pavilion in a research workshop, students' design with diverse forms also show the widely possible application of this structural concept.

doi	https://doi.org/10.52842/conf.caadria.2019.1.073
summary	This paper presents the design and construction of a 3D-printed thin bending-active formwork for shell. In order to use less scaffolding and make a dome with flexible material,3-D print is applied to the formwork. First step is form-finding . Two single -curved surfaces are used to fit the form found by Kanagaroo and then unroll them .Principle stress lines are also printed on the unrolled formwork to enhance it. However, the formwork with stress lines is hard to bend. So, bending-active simulation made by ABAQUS is also applied to find the best mesh pattern to bend. Bend the basic pattern first on the framework and then print Principle stress lines onto it. Karamba is used to simulate the deformation of the shell under gravity load. It is proved that grid made up of stress lines have the best performance The full scale prototype is made up of two pieces shell bent and tied together can stand steadily. Spring-back test shows that the second layer printed on the shell can help to provide deformation.

summary	Evolutionary computation is a population-based problem solver that is characterized by a stochastic optimization in order to solve both a single objective and multiple objectives. Previous evolutionary computational researches provided various design options and improved optimization through being evolved with fitness criteria, especially when multiple design objectives conflict with one another. In this paper, a rule-based algorithm was combined with the evolutionary computational process to propose an assembly logic of the modules and to improve an architectural building design in order to adapt to environmental changes. Two algorithms - a rule based and generative algorithm- proceeded simultaneously and provided various options as well as optimization in real time. For the experiment set-up, existing buildings were divided into each module; the modules were reinterpreted and reassembled with the logic driven by Evolutionary Developmental Biology. The conclusion is that when a rule based logic is combined with a developmental algorithm with a modular system, it is more efficient for the design process to be analyzed, evaluated, and optimized. The ultimate outcome provides various options in a short amount of time.

title	The Effect of Hygroscopic Design Parameters on the Programmability of Laminated Wood Composites for Adaptive Façades
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, p. 435
summary	Typical adaptive façades respond to external conditions to enhance indoor spaces based on complex mechanical actuators and programmable functions. Hygroscopic embedded properties of wood, as low-cost low-tech programmable material, have been utilized to induce passive motion mechanisms. Wood as anisotropic material allows for different passive programmable motion configurations that relies on several hygroscopic design parameters. This paper explores the effect of these parameters on programmability of laminated wood composites through physical experiments in controlled humidity environment. The paper studies variety of laminated configurations involving different grain orientations, and their effect on maximum angle of deflection and its durability. Angle of deflection is measured using image analysis software that is used for continuous tracking of deflection in relation to time. Durability is studied as the number of complete programmable cycles that wood could withstand before reaching point of failure. Results revealed that samples with highest deflection angle have least programmability durability.

title	A proposal for the use of fractal geometry algorithmically in tiling design
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, pp. 438-453
summary	The design inspired by nature is an ongoing issue from the past to the present. There are many design examples inspired from nature. Fractal geometry formation, which is focused on this study, is a system seen in nature. A model based on fractal growth principle was proposed for tile design. In this proposal made with using Visual Programming Language, a tiling design experiment placed in a hexagonal grid system was carried out. Thus, a base was created for tile designs to be made using the fractal principle. The results of the case study were evaluated and potential future studies were discussed.
