title	The Forbidden Symmetries

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.

summary	Architecture today has come to its most complex form. There are lots of criteria such as fi re safety, structure, sustainability etc… which must be controlled by the designers. To improve the performance and accessibility of buildings, governing bodies publish different codes for each of the different criteria. Buildings must comply with these codes to get a permit for construction. The checking of the buildings according the codes is done manually by code offi cials. This process is time consuming, high in cost and prone to errors. To remedy this problem by using the tools like BIM and AI, systems that can automatically check the code compliance of projects are being developed. In this paper we provide an overview of the structures and capabilities of these systems and present the automated code compliance checking system that we develop for checking building models against some parts of the Turkish Fire Codes.

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	Running Interference: Complex Systems Intervention as Design Process
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 183–192
doi	https://doi.org/10.52842/conf.caadria.2012.183
summary	This paper presents a case study problem statement tested in the design studio with the intent of teaching methods for engaging systematic thinking as a process for deriving solutions to parametric design problems. The intent is to address the simulation environment developed through complex systems and interject a curve ball, or unexpected constraint delimiting the solution as part of the design process. This method was tested through the submittal of the projects to international design competitions. The students were asked to manipulate the competition criteria by appealing not only to the design criteria but also to the juries desire (whether conscious or unconscious) for novel sustainable processes of material usage and program. This material ecology is developed as a method for linking parametric modelling, not as a process for the application of a construction technique, but as a way to pre-rationalise material constraints and discover how program and form can operate within those constraints. In the first year of the studio two of six teams were selected as finalists and in the second year of the studio five of seven of the teams were selected as finalists.

title	Sphere mapping: A method for a responsive surface design
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 527–536
doi	https://doi.org/10.52842/conf.caadria.2012.527
summary	The method proposed in this project addresses the parametric manipulation of a given pattern to respond directly to a pre-defined surface. Continuing the research of Kevin Rotheroe, Yale University and founder of FreeForm Design. Rotheroe has developed a series of studies in material and surface properties. By utilising a proven pattern, the proposed method sets parameters derived from the formal properties of the original pattern and produces a new pattern that is responsive to the curvature of a complex surface. The workflow developed in this research consists of a complex blending of tools in Grasshopper and Gehry Technologies Digital Project. The intent is to achieve the aesthetics and structure offered by Rotheroe’s original research and to add a responsive precision that provides an accurate adaptation of the pattern based on curvature of a specific computationally defined surface.

title	Resilient Rules - Culture and Computation in Traditional Built Environments
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. 211-221
summary	This study explores the influence of the socio-cultural rules, based upon Islamic jurisprudence (fiqh), on the complexity of the traditional built environment. This system of rules organized the societal activities, including decisions and activities related to design and construction in the Arab-Islamic city. Considering the city as a complex system, the study will try to show how this rules system made the Arab-Islamic city resilient and adaptive. Complex Adaptive Systems (CAS) are non-linear, self-organizing systems that have the ability to adapt to changing conditions through changing the rules that organize the random autonomous interactions between agents in the environment. This adaptation takes place through gradual gained experience that is reflected in the behavior of agents. This study attempts to interrelate different bodies of literature (Complexity/Chaos theory and built environment studies) in a single framework that aims to show that the socio-cultural rules system based on fiqh was a major factor in the resilience of the traditional built environment. These interrelations are illustrated using a graph called Computational Rules Graph (CRG). The CRG relates the traditional rules system to attributes of complex systems in a graph that can be modeled computationally. Traditional rules (codes of conduct) are proscriptive (non-deterministic), defining what is prohibited, thereby producing autonomous environments where agents had control over their immediate environment. In comparison, contemporary rules of the built environment (building codes) are prescriptive (deterministic), subscribing definite actions that need to take place by the stake-holder (agent) neglecting user needs and preferences. The application of these traditional rules system increased the agent’s autonomy and freedom of action. It also helped establish stronger social networks among agents, which resulted in a resilient environment.

title	Edible Infrastructures: Emergent Organizational Patterns for the Productive City
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
doi	https://doi.org/10.52842/conf.acadia.2012.511
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	Digital and Physical Tools for Industrial Robots in Architecture: Robotic Interaction and Interfaces
source	International Journal of Architectural Computing vol. 10 - no. 4, 541-554
summary	The development of digital and physical tools is highly dependent on interfaces, which define the terms of interaction both between humans and machines, as well as between machines and other machines.This research explores how new, advanced human machine interfaces, that are built upon concepts established by entertainment electronics can enhance the interaction between users and complex, kinematic machines. Similarly, physical computing greatly innovates machine-machine interaction, as it allows designers to easily customize microcontroller boards and to embed them into complex systems, where they drive actuators and interact with other machines such as industrial robots.These approaches are especially relevant in the creative industry, where customized soft- and hardware is now enabling innovative and highly effective fabrication strategies that have the potential to compete with high-tech industry applications.

doi	https://doi.org/10.52842/conf.acadia.2012.479
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.

summary	The research topic of this paper exemplifies design optimization techniques of a hotel/office tower in Central China (Nanjing city), which faces subtropical humid climate throughout the year. The main intent of the project is to fi nd optimized design solution with the aid of parametric design tools and Visual Basic Scripting techniques (in Rhino Script & Grasshopper) combined with intuitive design process. In any urban context, we firmly believe that architectural design is a responsive phenomenon, which faces diverse interaction with the user & the local climate. The building design of the proposed tower acknowledges these responsive factors of the design with the environment along with building users or residents. Consequently, we strive to develop a sustainable design solution, which is ecologically efficient and psychologically conducive to the wellbeing of the user. We developed our intuitive design product with complex computational design toolsets to leverage design and energy efficiency. In this procedure, we draw major design concepts and geometrical typologies from natural systems in the form of bio mimicry or biologically inspired design process. Overall, this research paper outlines the significance and relevant benefi ts of the combination of intuitive design (from experience, expertise and architects skills) with parametric scripting tools.

source	In Petruschat and Adenauer (eds), Neue Formen des Prototypings in Gestaltungsprozessen, Form+Zweck, Berlin, 2012
summary	Architects by profession, Christian Derix and Asmund Gamlesæter are interested in expanding the capabilities of digital technology to inform, support and enrich the design process in architecture and spatial planning. The computational prototypes they develop range from form studies to visualization of complex processes in spatial planning such as movement behaviors of people in a city. They work analytically as well as generatively and the approach is deeply affected by the understanding that computing systems should not define solutions but offer creative freedom and create a symbiosis between the designer and the algorithmic intelligence. They are rather designed to help the designer view the design problem and consequences of decisions from different perspectives. Encouraging the designer to play through different narratives. They are rather tools for thinking through multiple solutions and allow the designer to play with the possibilities. The generation of the final design is inspired and validated by the tools but remains in the hands of the designer.

title	Computational Design of a Bio Inspired Responsive Architectural Façade System
source	International Journal of Architectural Computing vol. 10 - no. 4, 613-633
summary	This research intends to illustrate a nonlinear relationship that could be drawn between the fundamental processes in living systems and architectural design of responsive surface.The research focuses on deriving a set of parametric relationships from the phenomenon in cell biology and generating an architectural expression of a responsive fac_ade system.The research methods primarily investigates the cell – to – cell connection in mammary epithelial cell system and review the evident relay of communication across the entire system of cells .This thorough investigation unfolds the logical parameters of the biological system that delineates the dynamic feedback mechanism and changes in the cell surface conditions initiated from the changes in the extra - cellular environment (ECM).The research findings of this complex mechanism are further translated though parametric modeling tool (in this case Generative Components) to model the causalities of the changes in cell environment and surface condition changes. In the next phase of our research we have explored the architectural utility of this hybridized model operating in a user defined controlled environ, and not just a mere response to biological stimulus.

summary	With the invention of computers, Architecture and other Engineering disciplines have undergone revolutionary developments offering new opportunities for improving efficiency and opening new frontiers for creativity. For example in architecture and urban planning, the discussions have been extended from conventional writings to cover cyberspace, virtual architecture and digital city. Moreover, computers have helped in the realization of many complex projects that would be inconceivable with traditional drawing techniques. This is clearly demonstrated in the works of Frank Gehry's, Zaha Hadid, Daniel Libeskind and many others. In deed, digital techniques have changed the design creative process and how the architects think. Traditionally the structured development architectural ideas from 2D drawings (plans, sections, elevations) towards 3D resolution has been replaced by more interactive approach of 2D & 3D. The changes that digital techniques have brought to the field of Architecture; including practice and education, can obviously be viewed from different angles and incite many discussions and questions. However, the purpose of this presentation is to discuss the role of digital techniques within the overall framework of project management in Gulf Housing Engineering. It starts the discussion with a brief on architecture and digital techniques in the Gulf Region, especially during the “boom period”; a period characterized by rapid production of buildings relying heavily on virtual images. It is against this background, the role of digital techniques is evaluated from a practice point of view. In fact in GHE, digital means are integral parts of the holistic project delivery process starting form initiation, to various design stages to construction ending with project completion. In this process emphasis is paid to the inter-relationships between IT Systems and Quality Control which in turn facilitate measuring, monitoring and reporting on various managerial, technical and design and budgetary aspects of the project. The presentation is supported by real case studies of GHE portfolio. It emphasizes that digital techniques should be an integral part of an overall process and should be seen as means to enhance efficiency and creativity; and should contribute to the betterment of the built environment

doi	https://doi.org/10.52842/conf.acadia.2012.139
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	This article aims to promote the discussion about how the adoption of Building Information Modeling systems in management processes and three-dimensional geometric modeling can interfere in the design process and construction of complex shapes in architecture. To that end, we assembled a theoretical-practical referential about the use of non-Euclidean forms in contemporary architecture and BIM tools, illustrated with iconic design processes developed by Frank Gehry and Zaha Hadid. Finally, there was the importance of BIM tools to a new understanding of architecture, by enabling the construction of complex shapes.

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
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.

summary	This paper will demonstrate two effective facade rationalisation patterns developed at Gehry Technologies for mitigating the tradeoffs between project constructability constraints vs. project aesthetic constraints. The two Case-Studies will present, fi rstly a method for dealing with large amounts of component instantiations and second with the economical delivery of complex project geometry through panelling. Both projects use design technology as a strategy for the integration of specialized knowledge and trades, through an effective use of information technology. The Case Studies will present the development of the Gridshell Digital Mock-Up of the Yas Island Marina Hotel in Abu Dhabi designed by Asymptote Architects and secondly the Museo Soumaya facade system in Mexico City designed by Fernando Romero LAR. This document will report the development process for obtaining relevant construction information, essential for the assembly of the facade systems by a third-party sub-contractor in support of the facade system coordination. The report concludes on the implementations of bespoke tools in support of the coordination and geometry description tasks. The tailored tool making process extends the parametric modelling system Digital Project™ in the design support role of obtaining aesthetically pleasing decompositions of the buildings Master Design Surface MDS into feasible constructible components.

summary	This paper explores the potential of smart, moveable building components to achieve customized shading, variable privacy properties, and introduce complex visual qualities. The research combines performative design strategies and sustainable design principles, with parametric modelling and digital fabrication, within the contemporary theoretical and cultural context. The focus of this research is on architecture where physical movement is an integral part of the primary functional and formal nature of the building component. With embedded computing using input and output devices, the systems are no longer static but dynamically move and respond. The paper presents several case studies of working prototypes.

summary	Exploring problems through multiple alternatives is a key aspect of design. In this paper, we present a prototype system as an extension to existing parametric CAD tools that enables parallel generation and editing of design alternatives. The system is built on two fundamental ideas. First, use of subjunctive dependency graphs enables simultaneous work on multiple design variations. These graphs capture and reveal complex data flow across alternative parametric CAD models. Second, prototype-based modeling provides a weak notion of inheritance enabling incremental description of differences between alternatives. The system is intended to be general enough to be used in different CAD platforms and other systems using graph-based modeling. The three basic system functions are definition of alternatives (variations) using prototype-based modeling, structural and parametric divergences of the prototypes, and interactive comparison. The goal of this research is consistent with the general qualities expected from any creativity support tools: enabling exploration and simultaneous development of variations.
