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	Interactive Form-Finding for Biomimetic Fibre Structures: Development of a Computational Design Tool and Physical Fabrication Technique Based on the Biological Structure of the Lichen

summary	This contribution shows a biomimetic approach to design and produce fibrous structural elements derived from the morphology of the biologic archetype ‘the lichen’. The physical form fi nding strategy allows for a novel self-organised reinforcement for fibrous composite systems. A computational design tool has been developed, based on the fi ndings of various physical models. The digital device allows for shape control and therefore an interaction to and manipulation of the fabrication process. Since the form fi nding algorithms of the tool are based on physical experiments,every geometry is derived through the program and has its counterpart in production. For example: the fibre density in the model can be adjusted which leads to different geometries. In production the chosen denseness is utilised, thus, the production yields automatically to the desired load-optimized geometry found in the form-finding tool.

title	Virtual Mock-up Simulation of Building Skins for Design to Fabrication Integration
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 467-470
summary	With the growing demand for mock-up integration into late design and pre-construction phases, there is an increasing gap between the virtual design model of the building and the construction model. The gap is reinforced by lack of strong iterative exchanges between design and fabrication and consequently the construction of the building skin systems. This paper will discuss the research being conducted using virtual mock-ups as an earlier insertion of fabrication parameters into design process and presents a solution to bridge this gap. Studies of model integration will be introduced using component-based 3D-CAD modeling to link front and end user scenarios.

title	Gramáticas da forma e modelagem paramétrica – uma aplicação na área da arquitetura paisagística [Shape grammars and parametric modeling – an application in the field of landscape design]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 397-400
summary	The objective of the present paper is to propose a design solution database to help students learn basic landscape design concepts and help them apply this new knowledge by using examples developed by an experienced designer. The system is based on an ontology that contains classes of design concepts and design instances. Beyond the structure to search for design concepts and precedents, it’s also proposed an interactive module implemented in a parametric design tool. This module allows students generate and insert automatically different parametric components, such as a group of trees, bushes, sculptures, in a digital model. The system efficacy was verified in a workshop performed with undergraduate students.

summary	The emergence of quasi-periodic tiling theories in mathematics and material science is revealing a new class of symmetry, which had never been accessible before. Because of their astounding visual and structural properties, quasi-periodic symmetries can be ideally suited for many applications in art and architecture; providing a rich source of ideas for articulating form, pattern, surface and structure. However, since their discovery, the unique long-range order of quasi-periodic symmetries, is still posing a perplexing puzzle. As rule-based systems, the ability to algorithmically generate these complicated symmetries can be instrumental in understanding and manipulating their geometry. Recently, the discovery of quasi-periodic patterns in ancient Islamic architecture is providing a unique example of how ancient mathematics can inform our understanding of some basic theories in modern science. The recent investigation into these complex and chaotic formations is providing evidence to show that ancient designers, by using the most primitive tools (a compass and a straightedge) were able to resolve the complicated long-range principles of ten-fold quasi-periodic formations. Derived from these ancient principles, this paper presents a computational model for describing the long-range order of octagon-based quasi-periodic formations. The objective of the study is to design an algorithm for constructing large patches of octagon-based quasi-crystalline formations. The proposed algorithm is proven to be successful in producing an infinite and defect-free covering of the two-dimensional plane.

title	Agent-Based Social Pedestrian Simulation for the Validation of Urban Planning Recommendations
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 332-336
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	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	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.

summary	Contemporary explorations within the evolutionary computational domain have been heavily instrumental in exploring biological processes of adaptation, growth and mutation. On the other hand a plethora of designers owing to the increasing sophistication in computer aided design software are equally enthused by the formal aspects of biological organisms and are thus meticulously involved in form driven design developments. This focus on top-down appearance and surface condition based design development under the banner of organic architecture in essence contributes to the growing misuse of bio-inspired design and the inherent meaning associated with the terminology. HyperCell, a bio-inspired information design framework for real-time adaptive spatial components, is an ongoing research, at Hyperbody, TU Delft, which focuses on extrapolating bottom-up generative design and real-time interaction based adaptive spatial re-use logics by understanding processes of adaptation, multi-performance and self sustenance in natural systems. Evolutionary developmental biology is considered as a theoretical basis for this research.

title	Three Dimensional Reconstitution of an Old Town from Historical Documents: Case of the Medina of Jijel in Algeria
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. 191; 285-303
summary	The three-dimensional reconstitution of cities and urban tissues was the subject of several studies and researches. In order to obtain the acquisition of the geometry of architectural or urban sets, some studies are based on Photogrammetric or on computer vision. Others have focused on the development of tools of acquisition from a laser providing a 3D scatter plot. Some of them yet focused towards the development of CAD software. The automatic generation for morphological 3D representation based on the exploitation of the architectural knowledge basis is also an option. This type of work becomes more relevant and legitimate when it concerns old cities in state of ruin or more simply missing whose remains only prints or literary descriptions similar to our case study; the old town of Jijel that many people ignore its existence. The aim of this work is to achieve a 3D reconstitution of buildings of this town based on historical documents, mostly prints, digitized old maps and plans, as well as literary texts (tales of travelers, military records, and history books). The method developed can solve and generate possible urban volumes in the most frequent cases. The 3D model obtained, despite its geometric simplicity, can view the city from different angles and open new opportunities for research in history, architecture and town planning.

summary	This article refl ects on the digital reconstruction of the Vinohrady Synagogue in Prague, which was demolished in 1951. Based on an international collaboration through the Erasmus program, expertise derived from other Viennese synagogue reconstructions at TU Vienna was combined with a resource organization methodology developed at KU Leuven. The reconstruction process is carried out using BIM software, which poses some particular attention on the software methodology and model structure, but at the same time illustrates the added value of a BIM approach, when comparing with more traditional CAD modelling systematics. Of particular interest is the approach for modelling complex geometry, integrating with more traditional 2D documents and for visualizing reconstruction assumptions within the 3D model representation.

summary	This paper develops a methodological approach for use in design practice which combines an external simulation tool (EnergyPlus™) with an evo-lutionary optimisation strategy for the form-finding of complex fenestra-tion systems. On one hand, based on previous research, it presents a novel approach for the shape morphogenesis that exploits a generative algorithm technique to control a limited set of parameters whilst on the other hand it facilitates the integration of a simulation tool capable of handling increasing levels of complexity with greater data interoperabil-ity. In doing so it will argue the heuristic potential of the proposed meth-od in aiding the designers’ decision making whilst increasing the formal possibilities of their final design solutions.

title	Shading With Folded Surfaces: Designing With Material, Visual and Digital Considerations

summary	This paper analyses a hybrid design approach; how physical and digital processes can inform each other in a multivalent design cycle. It describes the design of origami-inspired window shades, part of the Shaping Light project that explores how adjustable surface structures can modulate light levels and heat gain in response to the changing seasons. The screen uses sloped surfaces to diffuse light and create apertures that close when the screen is stretched and open when the screen is folded. The project complements digital methods for pattern proportioning and kinetic simulation with manual manipulation to generate 3D folding motifs and refi ne assemblies. Physical prototypes can shape digital refi nement by revealing visual and structural characteristics of materials, along with joint and production considerations. Physical models for simulating sunny and cloudy daylighting conditions provide a direct connection between spatial confi guration and visual effects. The paper concludes with guidelines for material-based digital-analog creation.

title	Some advice for migrating to IFC
doi	https://doi.org/10.52842/conf.caadria.2012.265
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 265–274
summary	Nowadays, the BIM (Building Information Modelling) paradigm is a central topic in the CAAD community. Next to the commercial solutions, the IFC (Industry Foundation Classes) have emerged as the best open standard candidate for BIM interoperability. Despite the efforts of the community for promoting IFC over the last 15 years, it seems that its practical adoption in real-life projects has been very limited. The goal of this article is to explore how useful IFC can be today and to provide the reader with some advice for an effective adoption of IFC. Over the last year, we have conducted a project aiming at acquiring a sound understanding of IFC. It was made of two complementary investigations. On one hand, we have focused on the commercial modelling tools and the IFC support they were offering. On the other hand, we have focused on the IFC-based software developments. We have developed a tool converting IFC files into a dedicated thermal assessment based model. We will summarise the experience we have acquired in this project into some advice for users migrating to IFC. Our goal is to confront the practical aspects of the IFC developments, with both the theoretical ambitions and the commercial support currently available.

summary	This paper discusses the potential of emerging digital representations of built environments coupled with agent-based modelling (ABM). A new set of urban transportation data is provided as an input which is the electric vehicles (EVs) population of one of the UK metropolitan areas. The study is a part of a PhD research that focuses on investigating computer-aided software to develop a virtual route for electric mobility in the North Sea Region. An overview of agent-based simulation platforms is discussed. Electric mobility system has particular paradigms that differ from conventional urban transport systems; a comparison is presented followed by the recommended approach of integrating the two techniques (visualization and simulation). Finally, the architecture of agents’ algorithm within the EVs network is presented through a case study of virtual Newcastle-Gateshead model.

summary	This article focuses on the use of both shape grammar and space syntax as tools to identify and encode the principles and rules behind the adaptation of existing houses to new requirements. The idea is to use such rules as part of a transformation grammar-based methodology for the rehabilitation of existing dwellings. The developed grammar is a specifi c grammar to inform the rehabilitation of a particular type of building in Portugal – “rabo-de-bacalhau”. In this article the goal is to explore how the “rabo-the-bacalhau” transformation grammar can be transformed in a general rehabilitation grammar in order to inform the rehabilitation of various types of housing buildings.

title	Creative Design Between Representation and Simulation
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. 11-12
summary	Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

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	Physics-Based Modelling can be considered as an alternative approach to geometrical constrain-based modelling for form-active material systems such as gridshells. Here we explain a vector-based method that works in R2 and R3 to determine momentum forces at the node level, which can easily be implemented into (existing) particle systems and - together with the simulation of tension and compression forces - can be used to model the behavior of such material systems.
