summary	Physical Digitality is the second volume of the conference proceedings of the 30th eCAADe conference, held from 12-14 september 2012 in Prague at the Faculty of Architecture of Czech Technical University in Prague. The companion volume is called Digital Physicality. Together, both volumes contain 154 papers that were submitted to this conference. Digitality is the condition of living in a world where ubiquitous information and communication technology is embedded in the physical world. Although it is possible to point out what is “digital” and what is “real,” the distinction has become pointless, and it has no more explanatory power for our environment, buildings, and behaviour. Material objects are invested with communication possibilities, teams are communicating even when not together, and buildings can sense and respond to the environment, each other, and to inhabitants. Digital is no longer an add-on, extra, or separate software. Reality is partly digital and partly physical. The implication of this condition is not clear however, and it is necessary to investigate its potential. New strategies are necessary that acknowledge the synergetic qualities of the physical and the digital. This is not limited to our designs but it also infl uences the process, methods, and what or how we teach. The subdivision of papers in these volumes follow the distinction made in the conference theme. The papers in Physical Digitality have their orientation mainly in the physical realm, and reach towards the digital part. It has to be granted that this distinction is rather crude, because working from two extremes (digital versus physical) tends to ignore the arguably most interesting middle ground.

summary	Digital Physicality is the first volume of the conference proceedings of the 30th eCAADe conference, held from 12-14 september 2012 in Prague at the Faculty of Architecture of Czech Technical University in Prague. The companion volume is called Physical Digitality. Together, both volumes contain 154 papers that were submitted to this conference.Physicality means that digital models increasingly incorporate information and knowledge of the world. This extends beyond material and component databases of building materials, but involves time, construction knowledge, material properties, space logic, people behaviour, and so on. Digital models therefore, are as much about our understanding of the world as they are about design support. Physical is no longer the opposite part of digital models. Models and reality are partly digital and partly physical. The implication of this condition is not clear however, and it is necessary to investigate its potential. New strategies are necessary that acknowledge the synergetic qualities of the physical and the digital. This is not limited to our designs but it also influences the process, methods, and what or how we teach.The subdivision of papers in these volumes follow the distinction made in the conference theme. The papers in Digital Physicality have their orientation mainly in the digital realm, and reach towards the physical part.

title	Aggregates: Digital design for design
doi	https://doi.org/10.52842/conf.caadria.2012.607
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 607–616
summary	This paper discusses an educational design methodology for undergraduate studio instruction, which uses a systematic and research based design approach. Based on Lars Spuybroek’s methodology that was originally developed as a one-year graduate and postgraduate studio, a new method for undergraduate teaching has been developed. The paper will discuss Spuybroek’s methodology, as developed for the graduate and postgraduate program, and explain its adaption for undergraduate studio instruction. Spuybroek’s approach is based on a model that starts with research in systems in general that is them tuned to a certain set of architectural questions and developed into parametric buildings in a stepwise procedure by delaying the specifics of site and program.

title	Simulando a dinâmica da segregação urbana: dos autômatos celulares aos modelos baseados em agentes [Simulating urban segregation dynamics: from cellular automata to agent based models]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 453-457
summary	As a consequence of the emergence of models based on the notions of disequilibrium and uncertainty, cities have being seen as intrinsically complex nonlinear systems subject to sociospatial changes that occur, simutaneously, in many scales. The present paper analyzes three models to simulate urban segregation dynamics. Schelling’s model shows how can emerge unexpected highly segregated global patterns from local preferences to live close to each other. Epstein and Axtell’s model reveals its pedagogic role through the manipulation of specific parameters. Portugali’s model emphasizes the cognition and learning capabilities of agents to recognize patterns and change their behaviour accordingly.

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	Numerical Simulation of Effect of Urban Geometry Layouts on Wind and Natural Ventilation Under Mediterranean Climate
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 195-202
summary	The use of the method "simulation" of the microclimate for an urban site presents much of interest; because this can serve as us observation and analysis of the consequences of various scenarios relating to the existence and the importance of the constituent elements in urban space. Wind in outdoor urban space is among the most difficult parameters to identify and control field given its instability. Currently, in the field of the ventilation, there are some outdoor spaces simulation tools, used to assess the flow of the wind at different spatial scales. The aim of this research is to demonstrate the effect of the urban geometry of the layout on the wind movement and the outdoor natural ventilation. However, this study investigated the effect on outdoor thermal comfort of a building layouts in a planned residential area situated in the city of Jijel humid Mediterranean region of Algeria. In order to improve outside comfort in this open space, a 3D numerical simulation tool ENVI-met 3.1 beta 4 was used to simulate the urban thermal climate taking into account various scenarios. Thus, simulation’s results are discussed in this paper

title	Generation of Energy-Efficient Patio Houses with GENE_ARCH: Combining an Evolutionary Generative Design System with a Shape Grammar
doi	https://doi.org/10.52842/conf.ecaade.2012.1.459
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. 459-470
summary	GENE_ARCH is a Generative Design System that combines Pareto Genetic Algorithms with an advanced building energy simulation engine. This work explores its integration with a Shape Grammar, acting as GENE_ARCH’s shape generation module. The urban patio house typology is readdressed in a contemporary context, both by improving its energy-effi ciency standards, and by rethinking its role in the genesis of high-density urban areas, while respecting its specifi c spatial organization and cultural grounding. Field work was carried out in Marrakesh, surveying a number of patio houses which became the Corpus of Design, from where a Shape Grammar was extracted. The computational implementation of the patio house grammar was done within GENE_ARCH. The resulting program was able to generate new, alternative patio houses designs that were more energy effi cient, while respecting the traditional rules captured from the analysis of existing houses. After the computational system was fully implemented, it was possible to complete different sets of experiments. The first experiments kept more restrained rules, thus generating new designs that closer resembled the existing ones. The progressive relaxation of rules and constraints allowed for a larger number of variations to emerge. Analysis of energy results provide insight into the main patterns resulting from the evolutionary search processes, namely in terms of form factors of generated solutions, and urban densities achieved.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 522-526
summary	This article aims to discuss the importance of freehand drawings in the architectural projective process in the context of the digital age, through the use of tablets. It is intended to identify how these drawings, using tablets, keep the perception and the personal dash of each one. This research aims not only to review and update the drawing´s disciplines in the architecture courses - its practices and procedures - but also to discuss the actual role of representation - analogical or digital - and its interaction with others disciplines. The first research, done in 2011, indicated possibilities of interface with CAD, Revit and Sketch-up. The second part, in course in this year, 2012, is trying to experiment the use of tablets in three others disciplines: History of Architecture and Urbanism I, Landscaping and Project I, in the Instituto de Arquitetura e Urbanismo da USP, São Carlos, Brasil.

summary	The Emergent Reefs project thrives on the potential that emerge from a coherent utilization of the environment’s inherent ecological structure for its own transformation and evolution, using an approach based on digitally simulated ecosystems and sparkled by the possibilities and potential of large-scale 3D printing technology. Considering tourism as an inevitable vector of environmental change, the project aims to direct its potential and economic resources towards a positive transformation, providing a material substrate for the human-marine ecosystem integration with the realization of spaces for an underwater sculpture exhibition. Such structures will also provide a pattern of cavities which, expanding the gradient of microenvironmental conditions, break the existing homogeneity in favor of systemic heterogeneity, providing the spatial and material preconditions for the repopulation of marine biodiversity. Starting from a digital simulation of a synthetic local ecosystem, a generative technique based on multi-agent systems and continuous cellular automata (put into practice from the theoretical premises in Alan Turing’s paper “The Chemical basis of Morphogenesis” through reaction-diffusion simulation) is implemented in a voxel field at several scales giving the project a twofold quality: the implementation of reaction diffusion generative strategy within a non-isotropic 3-dimensional field and integration with the large-scale 3D printing fabrication system patented by D-Shape®. Out of these assumptions and in the intent of exploiting the expressive and tectonic potential of such technology, the project has been tackled exploring voxel-based generative strategies. Working with a discrete lattice eases the simulation of complex systems and processes across multiple scales (including non-linear simulations such as Computational Fluid-Dynamics) starting from local interactions using, for instance, algorithms based on cellular automata, which then can be translated directly to the physical production system. The purpose of Emergent-Reefs is to establish, through strategies based on computational design tools and machine-based fabrication, seamless relationships between three different aspects of the architectural process: generation, simulation and construction, which in the case of the used technology can be specified as guided growth.

summary	In this paper we present a PhD research that aims to develop a design methodology that, using computational tools can generate livable spaces that allow the design of user centered architecture. We propose that a “corporeal architecture” might be able to work in a prophylactic or therapeutic way that can face some adversities generated by the contemporary impact of technology in the human body. We are using motion as the basis the tool to simulate the body’s motion as a spatial generator. We hope to understand how an embodied space, generated by motions that refl ect emotions, can create a sense of attunement with its dwellers. We also wish to achieve the holistic stimuli of the human body in a naturally immersive environment, with the induction of the body’s motions in space by the physical properties of the architecture.

title	Sense of Place in Virtual Heritage Environment: A Review
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 181-189
summary	The use of computer technology is becoming a necessity to many organizations particularly as a means of representation and visualization. In the context of culture and heritage it is often developed in the form of virtual heritage. This is due to the fact that some of these intangible values are faded or even lost in museums they are placed, or buried in its physical remains and ruins. The concept of portraying the richness of sense of place via the use of virtual reality (VR) technology is seen to be of great potential to give value to the heritage sites. Thus, VR allows a unique representation of the intangible heritage elements while evoking the user’s senses, emotions, memories, meanings and interpretations, though these are arguably complex to accomplish. This paper reviews literatures on factors that influence the character of place and sense of place, and the use of VR technology and virtual world design to suggest presence for virtual heritage development.

title	Constructing computational associations between ornamental designs

source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 37–46
summary	This paper presents the application of a computational model of association to the domain of real-world ornamental designs. The driving principle of the model, interpretation-driven association, is discussed with respect to its suitability to design applications. An implementation of the model is presented, in which associations are constructed based on topological and typological relationships within each design's structure, rather than based on literal similarities. Results are presented which demonstrate that the implementation and the model from which it was derived are capable of associating between real-world design objects.

summary	2D GIS has shown its limitations in many situations, especially when it’s applied in urban design. Many studies have been carried out to deal with the problem. Some attempted to link 3D visualisation to data stored within 2D GIS, and others tried to combine GIS, CAD and visualisation together. They all aim to meliorate current GIS for 3D applications. The authors of this paper developed a preliminary prototype of a 3D urban space information system based on Google Earth Plugin. It sets up a server to store and offer specific urban space information. With the desktop application that embeds Google Earth Plugin, user can upload and download models on the server, view them in the virtual 3D environment of Google earth, and make models directly in the 3D environment. A server-side database plays the role of managing information. This paper introduces the key ideas and methods of the system development, including system structure, set-up of the serve, server side information management, and interactive modelling functions.

title	Digital system of tools for public participation and education in urban design: Exploring 3D ICC

summary	This article is a starting point for the development of experiential urban co-design interfaces to enhance public participation in local urban projects and to be also used as a communication and collaboration tool in urban design. It is based on the previous research involving 3D city models utilized as understandable design interfaces for the non-technical public (Jutraz, Zupancic, 2011), where we have already explored different views (pedestrian, intermediate and bird’s-eye view), as well as the means by which the information obtained from these different views may be combined by shifting between viewpoints. Previous work was conducted in the “street lab” as well as the Urban Experimental Lab, which was developed specifi cally for the public’s participation in urban planning (Voigt, Kieferle, Wössner, 2009). Presented in this article is the next step that explores the immersive collaboration environment 3D ICC [1], formerly known as Teleplace. The environment was developed for effi cient collaboration and remote communication and shifts the research focus towards questions regarding how to employ both labs as interfaces between the non-technical public and design professionals. As we are facing the lack of digital systems for public participation and education in urban design, different digital tools for communication and collaboration should be combined into a new holistic platform for design. A digital system of tools needs to be developed that supports the urban design decision-making process and focuses on improved final solutions and increased satisfaction amongst all participants. In this article the system of digital tools for public participation, which include communication, collaboration and education, will be also defi ned, with its basic characteristics and its elements.

summary	The paper presents the current development of an ongoing research project about the integration of robotic fabrication strategies in computational design through morphological and functional principles derived from natural systems. Initially, a developed plate structure material system based on robotically fabricated fi nger joints is being informed by biomimetic principles from the sea urchin Clypeasteroida in order to be able to adapt effi ciently to its building environment. Consequently, the paper’s main focus lies on translating the biomimetic design principles into a computational design tool, also integrating fabrication parameters as well as structural and architectural demands. The design tool’s capability to integrate these parameters is shown by the design, development and realization of a full-scale research pavilion. The paper concludes with discussing the performative capacity of the developed material system and the introduced methodology.

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	A Method for the Realization of Complex Concrete Gridshell Structures in Pre-Cast Concrete
doi	https://doi.org/10.52842/conf.acadia.2012.209

summary	This paper describes a method for the design and fabrication of complex funicular structures fromdiscrete precast concrete elements. The research proposes that through the integration of digitalform-finding techniques, computational file-to-fabrication workflows, and innovative sustainableconcrete casting techniques, complex funicular structures can be constructed using prefabricatedelements in a practical, affordable, and materially efficient manner.A recent case study is examined, in which the methodology has been used to construct a pavilion.Custom-written dynamic relaxation software was used to define the overall form and successivealgorithms; it then defined each component’s unique geometry, unrolled into flat shapes, andnested all parts into cut-files. PETG plastic sheets were two-dimensionally laser cut and folded toproduce the unique casting molds. The case study was carried out in collaboration between theAarhus School of Architecture and the University of Technology, Sydney (UTS). Basic research incasting techniques defined the framework for the design process, and a custom-written dynamicrelaxation software application became the primary form-generating tool in the design process ofa constructed pavilion. Fabrication and construction constraints were embedded within the designof both the overall structure and its components. Finite element analysis [FEA] was completed inorder to verify the form-finding results, to ensure structural stability, and to direct adjustments ofthe structure during the design process.The constructed pavilion case study, constructed in a very short time, for low cost and with relativelyunskilled labor, demonstrates that the integration of algorithmic form-finding techniques, CNCfabrication workflows, and the use of innovative PETG folded-mold techniques enables thepractical realization of freeform funicular structures in precast concrete.
