title	Glass Cast: A Reconfigurable Tooling System for Free-Form Glass Manufacturing
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. 287-294

summary	Despite glass’s ubiquity in the modern built environment it is rarely applied in applications requiring complex curvature. The high temperatures and complexity of techniques utilized in forming curved glass panels are typically very expensive to employ, requiring dedicated hard-tooling which ultimately limits the formal variation that can be achieved. This combination of economic and manufacturing barriers limits both the formal possibilities and potentially the overall envelope-performance characteristics of the glazing system. This research investigates a methodology for utilizing reconfigurable tooling to form glass into doubly curved geometries, offering the potential for improved structural and environmental performance in a material that has remained largely unchanged since the advent of its industrial manufacturing. A custom built forming kiln has been developed and tested, integrated through a parametric modeling workflow to provide manufacturing constraint feedback directly into the design process. The research also investigates the post-form trimming of glass utilizing robotic abrasive waterjet cutting, allowing for the output of machine control data directly from the digital model. The potentials of the methodologies developed in this process are shown through the fabrication of a full-scale installation. By integrating material, fabrication, and design constraints into a streamlined computational methodology, the process also serves as a model for a more intuitive production workflow, expanding the understanding of glass as a material with wide-ranging possibilities for a more performative architecture.

title	Functionally Graded Aggregate Structures: Digital Additive Manufacturing With Designed Granulates
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. 295-304

summary	In recent years, loose granulates have come to be investigated as architectural systems in their own right. They are defined as large numbers of elements in loose contact, which continuously reconfigure into variant stable states. In nature they are observed in systems like sand or snow. In architecture, however, they were previously known only from rare vernacular examples and geoengineering projects, and are only now being researched for their innate material potentials. Their relevance for architecture lies in being entirely reconfigurable and in allowing for structures that are functionally graded on a macro level. Hence they are a very relevant yet unexplored field within architectural design. The research presented here is focused on the potential of working with designed granulates, which are aggregates where the individual particles are designed to accomplish a specific architectural effect. Combining these with the use of a computer-controlled emitter-head, the process of pouring these aggregate structures can function as an alternative form of 3D printing or digital additive manufacturing, which allows both for instant solidification, consequent reconfiguration, and graded material properties. In its first part, the paper introduces the field of research into aggregate architectures. In its second part, the focus is laid on designed aggregates, and an analytical design tool for the individual grains is discussed. The third part presents research conducted into the process of additive manufacturing with designed granulates. To conclude, further areas of investigation are outlined especially with regard to the development of the additive manufacturing of functionally graded architectural structures. The potentials of the methodologies developed in this process are shown through the fabrication of a full-scale installation. By integrating material, fabrication, and design constraints into a streamlined computational methodology, the process also serves as a model for a more intuitive production workflow, expanding the understanding of glass as a material with wide-ranging possibilities for a more performative architecture.

summary	In the fabrication of organic free-form shapes in architecture one is constantly faced with specifi c planning and design challenges. This paper examines these problems as well as possible solutions for the design of a completed and built prototype using the example of an organically shaped pavilion made of glass fi bre reinforced plastic modules. The paper describes which adjustments to the original design were required to take the step from “digital physicality” to “physical digitality” to realize a constructive and economically successful implementation. The solutions discussed combine modern digital software methods such as parametric design with innovative 3D modelling principles.

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.

summary	From the beginning of digital revolution, structural surfaces drew significant attention as a realm that interweaves formal explorations, form-finding and structural optimization. However, after successful experimentation in the virtual domain, it became evident that some of the main challenges lay on how to translate these structural forms into architectural assemblies at the scale of buildings. The development of digital fabrication is crucial in this task, as means to overcome traditional constraints such as need for modular pieces, scaffolding and optimal assembly sequences.This research focuses on digital workflows that combine form finding with robotic fabrication, surface tessellation and panelization. In the past years, the use of digital tools to assemble identical modules into complex formations has achieved significant results for loadbearing walls. Expanding this line of research, the proposed fabrication system carries these experiments on additive fabrication into the production of structural surfaces. The assembly sequence involves a two-step fabrication: off-site panel manufacturing and on-site assembly. The main components of the system consist of two triangular ceramic pieces that provide structural resistance, refined surface finish, and formwork for thin reinforced-concrete layer. Panelization strategies reduce the requirements on-site work and formwork.The paper describes background research, concept, construction process, methodology, results and conclusions.

summary	Digital Vernacular investigates the potential of the process of depositing a paste like material with precision using a CNC device which has produced an innovative system for design and fabrication of environmentally responsive housing. Architectural practice has been greatly impacted by technical innovations in the past, usually new building types emerge as part of new ideologies. Yet the current revolution in computer-aided design and fabrication has architecture focusing on form – without questioning what these new processes can bring for the masses. The research project 'Digital Vernacular' has investigated the potential of using CNC technology for the production of housing. It has focused on the design of the machinic devices as well as computational design tools, and revolves around the concept of fabrication on site. Using an additive and layered manufacturing process and locally available material, the project proposes a revolutionary new digital design and fabrication system that is based on one of the oldest and most sustainable construction methods in the world. The main potentials of this method are not to create complex forms for the sake of design, but to use parametric control to adapt each design to the specificities of its site. Using geometrical rules found during many research experiments with real material behaviour, a new architectural language is created that merges several environmental functionalities into a single integrated design.

summary	Why use the terms synthetic and ecology in the context of a conference dedicated to the field of digital architecture, computation and fabrication? How do we begin to unpack the synthetic union of diverse elements, processes, collaborators, and code underlying any single contemporary design or research project? What could our field gain by interrogating these diverse ecologies? What are the relationships and interactions between our design processes, including our various tools and techniques, and the multiple environments with which we routinely work, collaborate and make? It is these questions and more that we hope to address at this year’s “Synthetic Digital Ecologies” conference. A quick scan of the papers and projects that will be presented at ACADIA reveals an extraordinary ecology of experimental research that emerged by working between messy labs, studios, workshops, hacker spaces and the like. In many ways today’s so-called “digital architects” do not feel compelled to distinguish between what is digitally designed and what is not. They are leading the way through a promiscuous and synthetic mixing of skill sets, of pens and paper, hardware and software, electronics and g-code. In a single research project these designers might collaborate with a computer scientist, a robotics expert and a glass blower, and in many cases they might even attempt to do all of these things themselves. It was with this in mind that we put forth an international call inviting, “… architects, fabricators, engineers, media artists, technologists, software developers, hackers and others in related fields of inquiry …” to submit papers and projects for this year’s conference. This year the proceedings have been organized into twelve synthetic categories based around the potential for diverse research topics to inform new and unexpected conversations. Instead of organizing peer-reviewed papers and projects through their formal characteristics, we were interested in forming new synthetic categories by curating unexpected juxtapositions. This ecology of ideas and research was meant to provoke and inspire new ways of thinking, making, building and collaborating.

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.

title	Building Thailand's tallest Ganesh: CAD/CAM integration in conventional metal fabrication
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 337–346
doi	https://doi.org/10.52842/conf.caadria.2012.337
summary	Ganesh (Ganesa or Ganesha) is a Hindi god well known for his distinguishable elephant head and widely revered as the god of success or remover of obstacles. Patrons in Thailand have worshipped Ganesh and respected him by means of erecting statues of Ganesh in various poses and sizes throughout the country. In late 2008, the people of Chacheongsao, a province located East of Bangkok, decided to create Thailand’s tallest standing Ganesh statue made with bronze reaching heights up to 39 meters and situated on the Bangpakong river bank overseeing the city and its people. The author and design team was approached by representatives from Chacheongsao and commissioned to advise the process from conception to construction. The challenge started with seeking appropriate computer-aided design and manufacturing technologies and innovative processes to guide the design team throughout the production. The 0.60-meter bronze cast sculpture of the Ganesh was scanned using a 3D optical scanner to generate a solid model of the statue. A surface model was then extracted from the 3D model to firstly determine the most efficient structural support within the statue and secondly to generate surface strips for the foundry to create actual bronze casts. The construction of the project began early 2009 and the statue has since been erected from its base to currently its head. During construction, the author and design team has encountered several problems translating pixels to parts. Several errors have occurred during the mould and cast production process as well as construction errors on site causing mismatches of the structure and surface, misalignments, and protruding structural supports and joints. The lessons learned from this project is documented and analysed with hopes to create a more effective process for future projects with similar requirements.

summary	In the context of a wider inquiry on the integration of material properties and construction processes in computational models, this paper proposes a digital model for fabric formwork panels. Plaster cast in different types of fabric can produce a significant variation of resulting forms. The aim is to investigate whether data retrieved from physical models with 3D scanning techniques can improve the accuracy and efficiency of a simulation based on geometric principles, and better predict the behaviour of cast material in relation to the type of fabric. Setting up the computational model and choosing its parameters and constraints is based on the physical construction process, highlighting the relationship between material and form. As part of the cyclical exchange, evaluation of the digital model with physical testing demonstrates that the simulation can actually be trained by reducing the physical/ digital discrepancies.

title	Progress Towards Multi-Criteria Design Optimisation Using Designscript With Smart Form, Robot Structural Analysis and Ecotect Building Performance Analysis"
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. 47-56
doi	https://doi.org/10.52842/conf.acadia.2012.047
summary	Important progress towards the development of a system that enables multi-criteria design optimisation has recently been demonstrated during a research collaboration between Autodesk’s DesignScript development team, the University of Bath and the engineering consultancy Buro Happold. This involved integrating aspects of the Robot Structural Analysis application, aspects of the Ecotect building performance application and a specialist form finding solver called SMART Form (developed by Buro Happold) with DesignScript to create a single computation environment. This environment is intended for the generation and evaluation of building designs against both structural and building performance criteria, with the aim of expediently supporting computational optimisation and decision making processes that integrate across multiple design and engineering disciplines. A framework was developed to enable the integration of modeling environments with analysis and process control, based on the authors’ case studies and experience of applied performance driven design in practice. This more generalised approach (implemented in DesignScript) enables different designers and engineers to selectively configure geometry definition, form finding, analysis and simulation tools in an open-ended system without enforcing any predefined workflows or anticipating specific design strategies and allows for a full range of optimisation and decision making processes to be explored. This system has been demonstrated to practitioners during the Design Modeling Symposium, Berlin in 2011 and feedback from this has suggested further development.

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	This paper presents a concept of origami as a form-generator for a structural system that allows deployability for structures with large spans. The presented approach studies the embedded kinetic possibilities of folded structures and focuses on a parametric modelling process that allows evaluating the structural performance of different types of the same origami family in order to optimize the geometry for a given scenario. The workfl ow between scripting based form generation – within Rhinoceros and Excel – and LS-DYNA is presented in detail. In addition to that the question of scalability from a thin microstructure to a thickened roof structure is discussed in the context of an architectural project.

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.

summary	This paper explores the sonic characteristics of urban spaces, with the application of apprehending acoustic space and form theory. The theory defines auditory spaces as acoustical arenas, which are spaces defi ned and delineated by sonic events. Historically, cities were built around a soundmark, for example, the resonance of a church bell or propagation of a calling for prayer, or a factory horn. Anyone living beyond the horizon of this soundmark was not considered citizens of that town. Furthermore, the volume of urban sonic arenas depends on natural. Digital simulation is necessary to visualize the ephemeral and temporal nature of sound, within a dynamic immersive environment like urban spaces. This paper digitally analyses the different morphologies of old cities and forms of growth in relation to the sound propagation and ecological effects. An experiment is conducted with the aid of an ancient North-African city model, exposed to a point cloud agent system. By analysing how the sound propagates from the known soundmark through the urban fabric, with the wind pressure interference; the paper compares the theoretical concept of soundmarks and the known perimeter of the ancient city

title	Generation of Energy-Efficient Patio Houses with GENE_ARCH: Combining an Evolutionary Generative Design System with a Shape Grammar

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.

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.
