title	Zero-Waste, Flat-Packed, Tri-Chord Truss: Continued Investigations of Structural Expression in Parametric Design"
doi	https://doi.org/10.52842/conf.acadia.2012.199
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 199-208
summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models. This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes. This paper will expand (greatly) upon previous research into bi-chord truss designs, developing a tri-chord truss, which is parametrically linked to its structural moment diagram. The cross section of each truss is formed based on the loading condition for each beam. This truss design has been developed through a thorough series of analytical models and tests performed digitally, to scale and in full scale. The tri-chord truss is capable of resisting rotational failures well beyond the capacity of the bi-chord designs previously developed. The results are complex, and elegant expressions of structural logics embodied in a tightly constrained functional design.

title	Architecture of an Active Context

summary	As we stand with our feet on earth’s outermost surface we build an architecture today that is much like it was several thousand years earlier, in an attempt to extend that outer shell with one of our own making. Artificial masses are built from a refinement of this existing geologic layer into materials of stone, steel, concrete, and glass that assemble to produce new pockets of space through the buildings they create. However, the sixth century BC writer Thales of Miletus put a different perspective on this: he insisted that we live, in reality, not on the summit of a solid earth but at the bottom of an ocean of air (Holmyard 1931). And so, as architecture continues to build up the outermost layer of earth’s surface through a mimicking, embellishing, and enhancing of the materials which it comes from, it raises the question of why we have not brought a similar relationship to the materialities at the bottom of this “ocean” of air to create the spaces we call architecture. If you were looking to level a complaint with the architectural profession, stating that it has not been ambitious enough in scope would not be one. Architects have never shied away from the opportunity to design everything from the building’s shell to the teaspoon used to stir your sugar in its matching cup. But it would seem that the profession has developed a rather large blind spot in terms of what it sees as a malleable material with which to engage. Architects have made assumptions as to what is beyond our scope of action, refraining from engaging a range of material variables due to a belief that the task would be too great or simply beyond our physical control. So even though we are enveloped by them continuously, both on the exterior as well as the interior of our buildings, it must be assumed that the particles, waves, and frequencies of energy that move around us are thought by architects to be too faint and shaky to unload upon them any heavy obligations, that they are too unwieldy for us to control to create the physical boundaries of separation, security, and movement required of architecture. This has resulted in a cultivated set of blinders that essentially defines architecture as a set of mediation devices (surfaces, walls, and inert masses) for tempering the environmental context it is situated in from the individuals and activities within. The spaces we inhabit are defined by their ability to decide what gets in and what stays out (sunlight, precipitation, winds). We place our organizational demands and aesthetic opinions on the surfaces that mediate these variables rather than seeing them as available for manipulation as a building material on their own. The intention here is to recalibrate the materialities that make up that environmental context to build architecture. The starting point is a rather naive question: can we design the energy systems that course in and around us daily as an architectural material so as to take on the needs of activities, securities, and lifestyles associated with architecture? Can the variables that we would normally mediate against instead be heightened and amplified so as to become the architecture itself? That which many would incorrectly dismiss as simply “air” today—thought to be homogeneous, scale-less, and vacant due in part to the limits of our human sensory system to perceive more fully otherwise—might tomorrow be further articulated, populated, and layered so as to become a materiality that will build spatial boundaries, define activities of individuals and movement, and act as architectural space. Our environmental context consists of a diverse range of materials (particles and waves of energy, spectrum of light, sound waves, and chemical particles) that can be manipulated and formed to meet our needs. The opportunity before us today is to embrace the needs of organizational structures and aesthetics by designing the active context that surrounds us through the material energies that define it.

title	Robotic reticulations: A method for the integration of multi-axis fabrication processes with algorithmic form-finding techniques
doi	https://doi.org/10.52842/conf.caadria.2012.295
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 295–304
summary	This paper addresses the design and fabrication of non-uniform structural shell systems. Structural shells, particularly gridshells, have a long history but due to their complexity and the accompanying high cost of construction, their application has been limited. The research proposes a method for integrating the design and fabrication processes such that complex double curved reticulated frames can be constructed efficiently, from prefabricated components, requiring significantly less formwork than is typical. A significant aspect of the method has been the development of software tools that allow for both algorithmic form-finding and the direct control of robotic fabrication equipment from within the same modelling package. A recent case-study is examined where the methodology has been applied to construct a reticulated shell structure in the form of a partial vault. Components were prefabricated using 6-axis robotic fabrication equipment. Individual parts are designed such that the assembly of components guides the form of the vault, requiring no centring to create the desired shape. Algorithmically generated machine instructions controlled a sequence of three tool changes for each part, using a single modular fixture, greatly increasing accuracy. The complete integration of computational design techniques and fabrication methodologies now enables the economical deployment of non-uniform structurally optimised reticulated frames.

title	Application of Fuzzy Logic for Optimizing Foldable Freeform Geometries: An example of a practical application – a foldable window shade
doi	https://doi.org/10.52842/conf.ecaade.2012.1.709
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 709-717.
summary	This paper concerns the current discourse on computer-aided design tools for architectural design. There are drawbacks of purely analytic design tools which hinder a system-level, end-effect oriented ideation. For instance, most freeform quadrilateral meshes are fully constrained and therefore not capable of folding. They can only fold under special circumstances – when their geometry satisfi es the conditions of over-constrained kinematics. However, such intent of folding cannot be captured using simple modeling based on parameters and constraints. Furthermore, algorithmization of mesh kinematics using formulas is infl exible, it cannot handle topological variations, and it inhibits the interactive control of the model. In this paper, a fuzzy logic algorithm which uses a goal-oriented, human-like reasoning to control the parametric model is proposed. The algorithm applies easily observable behaviors of the geometry to adjust the selected patches until the entire shell can be folded. The algorithm relies on designer-observable characteristics of motion rather than on formulaic representations. Such approach directs the designers’ focus on the desired outcome while avoiding the drawbacks of analytic modeling of complex kinematics.

title	A System for Collaborative Design on Timber Gridshells
doi	https://doi.org/10.52842/conf.caadria.2014.441
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 441–450
summary	The bent timber laths of the Sound Bites gridshell create two types of performance space over an area of almost 100 m2. Such postformed gridshells are a wellestablished design solution for creating curved forms from linear elements. Extending principles developed since the 1970s, contemporary digital tools have been utilised to drive a renewed interest in them, primarily through so-called form-finding techniques which connect digital and material models through a simulation of shape under bending loads (Nettlebladt, 2013) and the definition of efficient structural geometry acting under compression loads only (Hernandez et. al., 2012). This paper describes the workflow conceived and implemented for the Sound Bites structure. A central challenge of the research was for such a workflow to allow for the principles of gridshell design to be engaged in parallel to other tight constraints and design drivers. As such it needed to facilitate close collaboration between architectural, engineering and fabrication experts. This workflow was tested in the design and realisation of the full-scale structure within a six-week period. The gridshell design was developed through the manipulation of the shape of two edge profiles and the shell form spanning between these. Architectural and fabrication constraints were met and the workflow allowed for a sufficient level of structural analysis to be fed back to inform the design.

summary	The goal of this project is a deeper understanding of the mechanisms that shape a city with a focus on pedestrian flow. Pedestrian flow reveals the use of space, the capacity and use of transportation and has an impact on the health of people. Movement patterns of pedestrians are a topic in many related fields like transportation planning, computer graphics and sociology. This project augments the simulation of pedestrian decision processes by taking into account the preferences for surrounding factors like additional points of interests and how pedestrians interact along their path with other pedestrians in a social manner. The goal of this project is to analyse urban planning configurations and to give designers and decision makers a tool to measure the amount of people walking and therefore define the health of a society, finding places of social interaction and improving social coherence in neighbourhoods.

summary	Pedagogical tradition is to focus its curriculums in studies that encourage the students in mental mechanisms which are favorable to the acquisition of a thought supported in the visual language and in the workshop. Current information technologies have produced a displacement in the ways the young people know, operate and relate to the world. A definitively cognitive shift has been provoked from the traditional written semantic decoding to visual semantic decoding, different operational skills have acquired, and a shift of intersubjetive communications from the personal experiential space to the virtual space.

title	Edible Infrastructures: Emergent Organizational Patterns for the Productive City
doi	https://doi.org/10.52842/conf.acadia.2012.511
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 511-526
summary	Edible Infrastructures is an investigation into a projective mode of urbanism which considers food as an integral part of a city's metabolic infrastructure. Working with algorithms as design tools, we explore the generative potential of such a system to create an urban ecology that: provides for its residents via local, multi-scalar, distributed food production, reconnects urbanites with their food sources, and de-couples food costs from fossil fuels by limiting transportation at all levels, from source to table. The research is conducted through the building up of a sequence of algorithms, beginning with the ‘Settlement Simulation’, which couples consumers to productive surface area within a cellular automata type computational model. Topological analysis informs generative operations, as each stage builds on the output of the last. In this way we explore the hierarchical components for a new Productive City, including: the structure and programming of the urban circulatory network, an emergent urban morphology based around productive urban blocks, and opportunities for new architectural typologies. The resulting prototypical Productive City questions the underlying mechanisms that shape modern urban space and demonstrates the architectural potential of mathematical modeling and simulation in addressing complex urban spatial and programmatic challenges.

title	“Divide et Impera” to dramatically and consciously simplify design: The mental/instance path - How reasoning among spaces, components and goals
doi	https://doi.org/10.52842/conf.ecaade.2012.1.269
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 269-278
summary	In our times, in a complex and universal village where problems are intertwined and pervasive beyond our imagination, we need new approaches to deal with them – appropriately. In a previous work we highlighted the importance to reason ontologies: a ‘world’ f.i. a building – as a mental image – is not a Linnaeus’s classifi cation (structured set of entities) but a system (goals oriented set of classes) able to reasoning upon selectively chosen entities belonging to different Realms (ontology universes) (Fioravanti et al., 2011a). The general aim of our research– to be an effective aid to design – is to simulate wo/man as designer and user of designed spaces, hence how mental skill can be computably included in new tools able to tackle these problems. This paper is focused on the fi rst role: how actor-designers approach design problems and how the inference mechanism can help them and affect the design process. A ‘Building Object’ - the dual system of Spaces and Technology elements – is inferred in several ways according to different goals and the inference mechanism can, simulating human mental shortcuts, optimize thinking.

summary	Presenting a hard-to-predict typography-varying system predicated on Nazi-era cryptography, this paper illustrates conditions under which unrepeatable phenomena can arise, even from straight-forward mechanisms. Such conditions arise where systems are observed from outside of boundaries that arise through their observation, and where such systems refer to themselves in a circular fashion. This illustration aims to show the dilemma of scientific design research: Objective outsiders are mystified while those subjectively involved understand.

summary	The general thematic of our work tackles the question of the generative design tool efficiency to stimulate a creative architectural conception in the context of sustainable development. We focus our point of view on the conceptual research phases. We would like to characterise the human creative mechanisms in a situation of generative assistance where digital tool reveals some degree of autonomy and incorporates environmental constraints. Thus, we implement an evolutionary design tool in which energetic performances of the analogon are used in order to orient the evolution. Our tool is based on an interactive genetic algorithm that ensures both a broad exploration of the solutions space and the subjective user preferences accounting. Users groups were confronted to the tool in a conception situation and creativity was evaluated and characterized.

summary	The composite photoreceptive field of the human eye receives photons emitted from a source and converts this energy into image information within the brain. The internal mechanisms of the contemporary camera imaging technologies represent yet another in a long history of attempts to technically replicate this procedure. The critical difference between the capacity of the human eye to receive quanta events or photons and that of a camera transmitting to a digital display device, rests in how much of the original signal can be recovered. This paper aims to show how the ‘information deficit’ associated with this technological conversion can be enhanced by the deliberate exploitation and re-arrangement of the camera’s image sensor mechanism. The paper will discuss how the mapping of pixel grid geometries and colour filter array patterns at the vastly increased scale of building façades, imparts a materiality to urban form that modifies the visibility and performance of the corresponding virtual screen image. The exploration of the material adaptation of pixel geometries leads to a new technique that extends the working gamut of pixel-based RGB colour space and both establishes an index to develop material performance criteria and modifies the limitations of traditional viewing technologies.

summary	We present an evaluation model to analyze ambient information systems, based on attentional mechanisms. Taking Weiser and Brown (1996) concepts of Ubiquitous Computing and Calm Technology as a starting point, we delimit ambient information systems as those that can be monitored without requiring the focus of our attention. Using the theoretical framework from Cognitive Psychology, we propose an evaluation model to analyze ambient information systems, considering the attentional mechanisms involved in their use. As a conclusion, we outline a set of parameters to be considered during the design of ambient information systems.

title	On Shape Grammars, Color Grammars and Sortal Grammars: A sortal grammar interpreter for varying shape grammar formalisms

source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp .479-487
summary	Grammar formalisms for design come in a large variety, requiring different representations of the entities being generated, and different interpretative mechanisms for this generation. Most examples of shape grammars rely on labeled shapes, a combination of line segments and labeled points. Color grammars extend the shape grammar formalism to allow for a variety of qualitative aspects of design, such as color, to be integrated in the rules of a shape grammar. Sortal grammars consider a compositional approach to the representational structures underlying (augmented) shape grammars, allowing for a variety of grammar formalism to be defi ned and explored. In this paper, we revisit and explore an exemplar shape grammar from literature to illustrate the use of different grammar formalisms and consider the implementation of rule application within a sortal grammar interpreter.
