summary	In the last two decades, CAD/CAM technologies have opened new conceptual and material opportunities in architecture. By combining computational design and digital fabrication technologies, architects have embraced a higher level of geometric complexity and variability in their solutions. Such non-standard possibilities were expanded with the recent introduction of robotic technologies in the discipline, which have allowed moving beyond the fabrication of building components to reach the construction of building parts. As a result of this digital condition, traditional materials have known innovative applications in architecture. In this context, this paper presents cork, which is a natural and recyclable material. By describing its unique set of properties and features, it argues about its relevance for the building construction in the present times. With this underlying motivation, this paper defines the current state of the research in architecture on the use of robotic fabrication with cork. It does so by describing and illustrating a set of different experiments conducted by the authors in their academic institutions. The results unveil a set of innovative applications of cork in building construction, and, at the same time, contribute to show how robotic technologies can be used to rethink and update traditional and old materials in architecture.

summary	This study focuses on developing three-dimensional solar panels, as an alternative to traditional flat Photovoltaic (PV) surfaces in Building Integrated Photovoltaic (BIPV). We propose to increase the energy efficiency of buildings by using the entire envelope for energy production as well as by increasing the efficiency of solar energy output in orientations which were traditionally considered as non-ideal. The panels are constructed from Polycarbonate with integrated flexible photovoltaic film, solar paint or dye. The methodology included digital algorithm-based tools for achieving optimized variable three-dimensional surfaces according to local orientation and location, computational climatic simulations and comparative field tests. In addition, the structural, mechanical and thermal properties of the integration between flexible PV sheets and hard plastic curved panels were studied. Interim results demonstrate a potential improvement of 50-80% in energy production per building unit resulting from geometric variations per-se. The dependence of energy production by surface geometry was revealed and an optimized method for solar material distribution on the surface was proposed. A parametric digital tool for automatic generation of optimized three-dimensional panels was developed together with a database and material models of the optimized panels system.

title	Digital Fabrication Methods of Composite Architectural Panels for Complex Shaped Buildings
doi	https://doi.org/10.52842/conf.caadria.2015.703
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 703-712
summary	Composite materials have been explored in architecture for their high performance characteristics that allow customization of functional properties of lightness, strength, stiffness and fracture toughness. Particularly, engineering advancements and better understanding of fiber composites have resulted in growing applications for architectural structures and envelopes. As most developments started outside the realm of architecture such as automobile and aeronautical industries, there is need to advance knowledge in architectural design to take advantage of this new technology. In this paper, the authors introduce preliminary results of new digitally driven fabrication methods for fiber-reinforced composite sandwich panels for complex shaped buildings. This research examined the material properties, manufacturing methods and fabrication techniques needed to develop a proof of concept system using off-the-shelf production technology that ultimately can be packaged into a containerized facility for on-site panel production. Experiments focused on developing a digitally controlled deformable mold to create composite relief structures for highly customized geometrical façade components. Research findings of production materials, methods, assembly techniques, are discussed to offer insights into novel opportunities for architectural composite panel fabrication and commercialization.

summary	This paper presents part of CORK’EWS, a research work developed within the framework of the Digital Architecture Advanced Program 2012/13 at ISCTE-IUL. The main goal of this investigation was to develop a parametric, customizable and adaptive wall system designed for environmental performance. Moreover, the system is based on standard industrial products: expanded cork blocks produced by Amorim Insulation industries. CAD/CAM resources were the essential tools of the research process, where fundamental and practical knowledge is integrated to understand the microstructure morphological properties of the raw material – cork – and its derivate – natural expanded cork. These properties were upscale and adapted to create a wall with an optimized solar control environmental performance. The result is a digitally fabricated prototype of a new customizable industrial product, adaptable to specific environmental conditions and installation setups being therefore easily commercialized. From microstructural morphology to macroscale construction, the research explores new application possibilities through morphogenesis and opens new possible markets for these customizable products.

title	Generative Processes in Tower Design: Simultaneous Integration of Tower Subsystems Through Biomimetic Analogies
doi	https://doi.org/10.52842/conf.acadia.2015.173
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 173-184
summary	The research presented in the paper formulates part of the methodological approach of a recently completed PhD thesis. The principle aim of the thesis is to achieve simultaneous integration of tower subsystems which can coherently adapt to their internal and external context during the initial phases of the design process. In this framework, the tower subsystems are grouped as the structural system, floor system, vertical circulation system, facade system, and environmental system. The paper focuses on the implementation of the specific biomimetic analogies towards the integration of tower subsystems through computationally generated dynamic systems. The biomimetic analogies are the mechanical and organizational properties of branched constructions, the mechanical properties of the bamboo stem, and the micro-structure of the porcupine quill/ hedgehog spine. Each biomimetic analogy is described in relation to the design domain. Methods of employing the mathematical and geometrical principles of the biomimetic analogies during design explorations are elaborated. Outcomes of the design output are outlined and discussed with a concentration on achieving tower subsystem integration, differentiation, and co-adaptation properties.

title	Form Follows Flow: A Material-Driven Computational Workflow for Digital Fabrication of Large-Scale Hierarchically Structured Objects
doi	https://doi.org/10.52842/conf.acadia.2015.185
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 185-193
summary	In the natural world, biological matter is structured through growth and adaptation, resulting in hierarchically structured forms with tunable material computation. Conventional digital design tools and processes, by contrast, prioritize shape over matter, lacking integration between modeling, analysis, and fabrication. We present a novel computational environment and workflow for the design and additive manufacturing of large-scale hierarchically structured objects. The system, composed by custom multi-barrel deposition attached to robotic positioning, integrates material properties, fabrication constraints and environmental forces to design and construct full-scale architectural components. Such components are physically form-found by digitally extruding natural polymers with functionally graded mechanical and optical properties informed by desired functionality and executed through flow-based fabrication. In this approach, properties such as viscosity, velocity, and pressure embed information in two-dimensional printing patterns and induce three-dimensional shape formation of the fabricated part. As a result, the workflow associates physical material and fabrication constraints to virtual design tools for modeling and analysis, challenging traditional design workflows and prioritizing flow over form.

title	C-Lith: Carbon Fiber Architectural Units
doi	https://doi.org/10.52842/conf.acadia.2015.069
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 69-79
summary	C-LITH is the reconsideration of the architectural building unit through the exploration of new composite techniques and materials. Our project develops individual compo- nents that exploit the strength, lightness, and variability possible with carbon ber laments when paired with computation, digital fabrication, and hand assembly. Traditionally, architectural units made of brick or concrete are small and multiple, heavy, dif cult to vary, and are much better in compression than tension. Using carbon ber laments to create variable units allows for larger individual units that can vary in both shape and structural performance as needed. Our units, developed through winding pre-preg carbon ber tow around disposable molds, bene t structurally from the quasi-isotropic properties that are developed through the winding patterns. The specific structural capacities of the units remain to be understood through further testing and analysis, which falls outside the scope of this current research. At this junction, structural capacities have been determined empirically, i.e. will it stand? Most importantly, as a formal study, our units address the use of carbon ber at the scale of architectural production. A majority of the effort involved in materializing C-LITH was the development of a two-fold prototypical manufacturing process that produces the components and assembly. For this we invented a method to quickly and cheaply construct variable cardboard molds that could withstand the wound casting and baking steps, but could also be easily weakened through water immersion to be removed. For the assembly we developed a rigid dummy-jig system to hold the joint plates in position with a high level of precision but could also incrementally absorb the adjustment errors unavoidable in hand assembly systems. Using a simple pin connection the resultant structures can be easily disassembled for transportation and reassembly elsewhere.

title	Expanding the Material Possibilities of Lightweight Prefabrication in Concrete Through Robotic Hot-Wire Cutting - Form, Texture and Composition
doi	https://doi.org/10.52842/conf.ecaade.2015.2.341

summary	In recent years, digital fabrication technologies have enabled renewed explorations into traditional materials, with innovative results. This paper focuses on concrete and on the potentials of a specific technology: robotic hot-wire cutting for the production of expanded polystyrene (EPS) formwork. Academia and industry have explored this process recently but the number of works built with this technology is reduced and the general concrete prefabrication industry has been slow to adopt it. In this context, this paper analyzes the use of EPS in the production of concrete formwork by reviewing its application in contemporary examples. In order to develop a clear assessment of the possibilities of expanding prefabrication in concrete using robotic hot-wire cutting, this paper also documents a set of practical experiments developed in the laboratory, addressing three material challenges: form; texture and composition. This research involved the design, formwork production and casting of concrete elements to explore the limits and characterize the process of robotic hot-wire fabrication in the context of concrete prefabrication. By recognizing the different approaches present in contemporary examples and in the explored practical experiments, we point out the advantages and limitations of using hot-wire cutting, and develop the reasons behind its limited application in practice.

summary	The research presented in this paper revolves around the experimental development of the morpho-structural potential of folded architectural structures made of wood. The aims are to develop an innovative system for timber used in sustainable construction and to increase the inventory of wood architectural tectonics. Laminated timber panels associated with "digital production line" approach have opened up new perspectives for the building industry in creating prefabricated wooden structures. This article provides a characterization of the digital chain associated to the development of non-standard folded structures which consist of wood panels by way of a full-scale experimental pavilion. The purpose is the study of architectural design process from parametric modeling (through CNC machining) and assembly operations to production. Towards the completion of the pavilion, a number of analytical experiments have been performed.

title	Alternative Fabrication Process for Free-Form FRP Architectural Elements Relying on Fabric Materiality Towards Freedom from Molds and Surface Articulation
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 397-410.
summary	FRP (fiber reinforced polymers) is a family of composite materials combining fibers and polymers to offer exceptional mechanical properties. Its unique material properties have led to its wide application across industries. Although we witness a growing interest in the material in the architectural field in recent years, a significant barrier to its application lies in the need for a mold. The paper describes a new alternative fabrication process for architectural FRP elements that relies on fabric materiality. It suggests a mold free process, combining form finding and garment making techniques, to allow for complex morphologies, surface articulation and variation. The paper describes both the fabrication process through physical experiments, as well as the design process through the use of two design software tools. It demonstrates the potential for sustainable variation of large component facade system.

title	Phototropism of Tensile Façade System through Material Agency
doi	https://doi.org/10.52842/conf.caadria.2015.127
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 127-136
summary	This paper researches material agencies, mechanical systems and façade designs that are able to respond to environmental changes through local interactions, inspired by biological systems. These are based on a model of distributed intelligence founded on plants and animal collectives, from which intelligent behavior emerges through simple local associations. Biological collective systems integrate material form and responsiveness and have the potential to inform new architectural and engineering strategies. The design approach of this research is based on a data-driven methodology spanning from design inception to simulation and physical modeling. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. The driving concepts are three types of evolutionary adaptation: flexibility, acclimation, and learning. The proposed façade system is a responsive textile shading structure which uses integrated actuators that moderate their local environments through simple interactions with their immediate neighbors. Computational techniques coupled to material logics create an integral design framework leading to heterogeneous environmental and structural conditions, producing local responses to environmental stimuli and ultimately effective performance of the whole system.

summary	The construction and building sector is now widely known to be one of the biggest energy consumers, carbon emitters, and creators of waste. Some architectural agendas for sustainability focus on energy efficiency of buildings that minimize their energy intake during their lifetime - through the use of more efficient mechanical systems or more insulative wall systems. One issue with these sustainability models is that they often ignore the hierarchy of energy within architectural design. The focus on the efficiency is but one aspect or system of the building assembly, when compared to the effectiveness of the whole, which often leads to ad-hoc ecology and results in the all too familiar “law of unintended consequences” (Merton, 1936). As soon as adhesive is used to connect two materials, a piece of trash is created. If designers treat material as energy, and want to use energy responsibly, they can prolong the lifetime of building material by designing for disassembly. By changing the nature of the physical relationship between materials, buildings can be reconfigured and repurposed all the while keeping materials out of a landfill. The use of smart joinery to create building assemblies which can be disassembled, has a milieu of new possibilities created through the use of digital manufacturing equipment. These tools afford designers and manufacturers the ability to create individual joints of a variety of types, which perform as well or better than conventional systems. The concept of design for disassembly is a recognizable goal of industrial design and manufacturing, but for Architecture it remains a novel approach. A classic example is Kieran Timberlake's Loblolly House, which employed material assemblies “that are detailed for on-site assembly as well as future disassembly and redeployment” (Flat, Inc, 2008). The use of nearly ubiquitous digital manufacturing tools helps designers create highly functional, precise and effective methods of connection which afford a building to be taken apart and reused or reassembled into alternative configurations or for alternative uses. This paper will survey alternative energy strategies made available through joinery using digital manufacturing and design methods, and will evaluate these strategies in their ability to create diassemblable materials which therefore use less energy - or minimize the entropy of energy over the life-cycle of the material.

summary	Research investigating water-driven passive actuation demonstrates the potential to transform how buildings interact with their environment while avoiding the complications of conventionally powered actuation. Previous experiments evidence the possibilities of bi-layer materials (Reichert, Menges, and Correa 2015; Correa et al. 2015) and mechanical assemblies with discretely connected actuating members (Gupta et al. 2019). By leveraging changes in weather to power actuated building components these projects explore the use of smart biomaterials and responsive building systems. Though promising the implementation of these technologies requires deep engagement into material synthesis and fabrication. This paper presents the design and prototyping of a rain responsive faÃ§ade system using chitosan hygroscopic films as actuators counterbalanced by programmed compliant mechanisms. Building on previous work into chitosan film assemblies this research focuses on the development of compliant mechanisms as a means of controlling movement without over-complicated rotating parts.

title	Generating Schematic Diagrams of MEP Systems from 3D Building Information Models for Use in Conservation

summary	In this paper, we propose a method of generating schematic diagrams from 3D models of mechanical, electrical and plumbing (MEP) systems in order to represent this information in a more traditional, user-friendly format. It can be difficult to grasp the relationships between various MEP elements in building information models (BIM) because they are represented in a visually complex, three-dimensional manner. On the other hand, the relationships between building elements can be easily understood when using traditional schematic diagrams. First, sets of connected elements are extracted from a 3D model of MEP elements using their connection properties. Next, various elements of these systems are identified as nodes and their connections are represented as edges. Finally, these systems are displayed as a schematic diagram using element attribute information.

summary	The thermal categories established by Reyner Banham are useful for identifying historical points at which structure is "liberated" from the task of being the prime controller of the environment, as well as identifying the impact on design culture, which given the freedom to invest structure with a high degree of sculptural plasticity, exaggerated the disconnect between form and thermal performance, resulting in a situation in which form is inherently viewed as incapable of performing work equivalent to mechanical systems.

title	Computational and Physical Modeling for Multi-Cellular Pneumatic Envelope Assemblies
source	International Journal of Architectural Computing vol. 13 - no. 2, 143-169
summary	This article describes recent research on the performative, formal and aesthetic potentials of multicellular pneumatic foil-based envelope systems for lightweight, responsive building skins able to control thermal insulation and air exchange with minimal amounts of energy and mechanical components. The prototype-based research involves the use of principles from biological examples of pneus, which inform the design of physical analogue models at an architectural scale. The process entails physical-computational feedback loops wherein physical performance findings are fed into computational design models for pneumatics and membranes, as well as modified energy models, in order to advance the predictive design capacities of simulation tools in designing such systems. In this process, material agency allies with computational agency to develop novel possibilities for dynamic pneumatic envelopes.

title	From material to material with new abilities. Performative Skin: an unfinished product derived through the organizational logic as developed through research on ‘movement’
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 631-636.
summary	This paper presents the process and products from research on ‘a movement behavior’, transforming the initial surface from one state to other states. The study developed an initial model of material organization inspired by nature: the adaptable exoskeleton of the armadillium vulgare. Through geometric analysis of functional variation in the exoskeleton’s unit shape, and physical model making, the underlying principle is translated into design & production rules. The generative model of ‘an adaptable segmented system’ is constructed through a geometric abstraction of the exoskeleton, achieving diverse functions such as variability in form, volume, porosity, flexibility and strength, through a distribution of ‘material geometry’ with the folding technique. The potentiality of this parametric physical model (based on simple systematicity) is questioned in relation to diverse situations that result in complex surface adaptations. This research shows the formulation of a design intention.

summary	Reticular systems are in many aspects a distinct taxonomy of volumetric geometries. In comparison with the conventional embodiment of a ‘volume’ that encapsulates a certain quantity of space with a shell reticular geometries emerge from the accumulation of micro elements to define a gradient of space. Observed in biological systems, such structures result from their material properties and formation processes as well as often ‘simple’ axioms that produce complex results. In micro or macro levels, from forest tree canopies to plant cell walls these porous volumes are not shaped to have a singular ‘solution’ for a purpose; they provide the fundamental geometric characteristics of a ‘line cloud’ that is simultaneously flexible in response to its environment, porous to other systems (light, air, liquids) and less susceptible to critical damage. The porosity of such systems and their volumetric depth also result in kinetic spatial qualities in a 4D architectural space. Built upon a ‘weaving’ organization and the high performance material properties of carbon fiber composite, this research focuses on a formal grammar that initiates the complex system of a reticular volume. A finite ‘lexical’ axiom is consisted of the basic characters of H, M and L responding to the anchor points on the highest, medium and lower levels of the extruding loom. The genome thus produces a string of data that in the second phase of programming are assigned to 624 points on the loom. The code aims to distribute the nodes across the flat line cloud and organize the sequence for the purpose of overlapping the tensioned strings. The virtually infinite results are then assessed through an evolutionary solver for confining an array of favorable results that can be then selected from by the designer. This research focuses on an approximate control over the fundamental geometric characteristics of a reticular system such as node density and directionality. The proposal frames the favorable result of the weave to be three-dimensional and volumetric – avoiding distinctly linear or surface formations.

title	Toward a Behavioral Design System: An Agent-Based Approach for Polygonal Surfaces Structures

summary	The following research investigates the development of an agent-based design method as an integrative design tool for polygonal surface structures. The aim of this research is to develop a computational tool that self-organizes the emergence of polygonal surface structures from interaction between its constitutive lattices. This research focuses on the ethological level of morphogenesis that is relevant to the animal or insect societies, whereby agents mediate the material organizations with environmental aspects. Meanwhile, behavior-based approaches are investigated as a bottom-up system to develop a computational framework in which the lower-level features constantly interact. The lower-level features such as material properties (e.g., geometric descriptions) are abstracted into building blocks or agents to construct the agent’s morphology. The abstracted principles, which define the agent’s morphology, are aggregated into a generative tool to explore the emergent complexities. This exploration coupled with the generative constraint mechanisms steers the collective agents system toward the cloud of solutions; hence, the collective behaviors of agents constitute the polygonal surface structures. This polygonal system is a bottom up approach of developing the complex surface that emerges through topological and topographical interaction between cells and their surrounding environment. Subsequently, the integrative system is developed through agent-based parametric modelling, in which the knowledge-based system as a top-down approach is substituted with the agent system together with its morphological features and significant behaviors.
