title	The Greenhouse & Cabinet of Future Fossils: Interfacing Nature in the Built Environment
doi	https://doi.org/10.52842/conf.acadia.2012.259

summary	The Greenhouse and Cabinet of Future Fossils was commissioned by the American Philosophical Society Museum, funded by Heritage Philadelphia Program, a program of The Pew Center for Arts & Heritage. The Greenhouse and Cabinet of Future Fossils attempts to gather, digest, and disseminate information about nature while also incorporating cutting-edge design and fabrication techniques to ultimately produce a greenhouse of the future. The pavilion structure is populated with cold frame modules and futuristic ceramic and 3D printed curiosities, prefabricated and assembled in the Jefferson Garden, Philadelphia. Taking inspiration from the artifacts in the exhibition, Of Elephants and Roses: Encounters with French Natural History, 1790–1830, the greenhouse revisits 19th-century thematic issues related to nature, culture, and the city to offer new interpretations of greenhouse architecture as urban hybrid ecosystems whose nonstandard form features new material and fabrication logics that inspire a shift away from a technical approach to sustainable architecture to one rooted in design and the built environment. The pavilion mobilizes concepts of event as the public is invited to actively participate in the planting of the cold frames, thus contributing to the actual secondary structure of the greenhouse, and then disassembling the structure at the end of the installation period and disseminating the planted materials. As a conceptual and provocative backdrop to this project, references are made to important contributions recently made by a small group of accomplished scientists, architects, and researchers at a university symposium whose central theme was to discuss next steps for sustaining sustainability.

title	Architecture of an Active Context
doi	https://doi.org/10.52842/conf.acadia.2012.269

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	Designing the Negative was the title of a Master Studio that took place at the Institute of Architecture and Media of Graz University of Technology during the summer semester of 2012. Students designed and fabricated prototypes of customized concrete formwork as part of their studio assignment. The studio theme forced students to think about digital fabrication with parametric tools in a hands-on fashion. Using robotic technology and hot-wire cutting, students worked with the robot’s constraints (size of the robot’s arm, robot’s axis and tool’s restrictions) to design complex curved elements that could serve as formwork (the negative) for cast concrete elements (the positive). The students were asked to design a production strategy for their cast concrete elements as well as the application of said elements in an architectural scheme. The student projects confirmed the value of a pedagogy that takes on research-relevant questions in an interdisciplinary studio setting and engages students in a process that is best described as digital crafting: it simultaneously addressed the conceptual and technical as well as the material and tactile aspects of digital fabrication and design.

title	Emergent Reefs
doi	https://doi.org/10.52842/conf.acadia.2012.139
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. 139-148
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	The composite photoreceptive field of the human eye receives photons emitted from a source and converts this energy into image information within the brain. The internal mechanisms of the contemporary camera imaging technologies represent yet another in a long history of attempts to technically replicate this procedure. The critical difference between the capacity of the human eye to receive quanta events or photons and that of a camera transmitting to a digital display device, rests in how much of the original signal can be recovered. This paper aims to show how the ‘information deficit’ associated with this technological conversion can be enhanced by the deliberate exploitation and re-arrangement of the camera’s image sensor mechanism. The paper will discuss how the mapping of pixel grid geometries and colour filter array patterns at the vastly increased scale of building façades, imparts a materiality to urban form that modifies the visibility and performance of the corresponding virtual screen image. The exploration of the material adaptation of pixel geometries leads to a new technique that extends the working gamut of pixel-based RGB colour space and both establishes an index to develop material performance criteria and modifies the limitations of traditional viewing technologies.

title	Directed Deposition: Exploring the Roles of Simulation and Design in Erosion and Landslide Processes

summary	Working with and against environmental processes, such as the movement of water, earth, and rock, and terrain, has been a perpetual challenge since the dawn of civilisation. While it has been possible to gradually tame many landscapes to perform in a predictable manner, there are many circumstances where we are forced to live with and around such processes in everyday life. This research is primarily interested in the potential of design to interact with such processes. Specifically, we are interested in the designed redirection of erosion and landslide processes already observable in nature, taking the urbanised hillsides of the Alps as test case scenario. The research specialisation continues a research and design focus specialised on processes material deposition of river and flood systems, further down the water catchment chain (REF: ANON 2012). This specific alpine research is compelling in the context of Anthropocene processes, we are specifically focussed in the appraisal, harnessing and redirection of existing environmental phenomena, given what can be understood as our inevitable interaction with these processes (Sijmons 2015). Within this broader research, which has ecological, cultural, and formal potential, this paper shall explore the practical aspects of connecting design, and the designer, with the potential for understanding and designing these evolving mountain landscapes. There is a long history behind the development of landscape elements which control avalanches, mud, rock, and landslides. The cultural, functional and aesthetic role of such elements in the landscape is relatively undiscussed, epitomising an approach that is primarily pragmatic in both engineering and expense. It is perhaps no surprise that these elements have a dominant physical and visual presence in the contemporary landscape. Through the investigation of synergies with other systems, interests, and design potential for such landscape elements, it is proposed that new potential can be found in their implementation. This research proposes that the intuitive linking of common design software to direct landslide simulation, design of and cultural use can interact with these natural processes. This paper shall demonstrate methods to within which design can enter the process of landscape management, linking the modelling processes of the landscape designer with the simulation capabilities of the specialised engineer.

title	Crowdsourcing Architecture: A Disruptive Model in Architectural Practice
doi	https://doi.org/10.52842/conf.acadia.2012.439

summary	This paper discusses the use of crowdsourcing as a new approach for architectural design acquisition. We will give an overview of the concept of crowdsourcing, and elaborate on its particular application in architecture via concrete projects executed on Arcbazar, a firstof- its-kind crowdsourcing platform for architectural design services. We argue that online crowdsourcing platforms can have an immense impact on smaller-scale design challenges, e.g., home remodeling projects and landscape and interior design challenges, and can potentially carry these often neglected projects into the architectural design sphere. In this paper we will discuss the methods and techniques of architectural crowdsourcing and illustrate the processes and outcomes through a series of projects: a remodeling project for a closet; an interior design challenge for a dining space; and a layout problem for an apartment complex. We will then evaluate the protocol and outcome of architectural crowdsourcing, and convey the professional and popular media response to this new method of architectural design acquisition.

summary	The working hypothesis of this research focuses on the potential of utilizing a digital toolset to engage information within a surrounding context for the purpose of creating a more intelligent pre-cast concrete panel system. The Parametric Pre-Cast Concrete Panel System is a research project attempting to parametrically define geometry for the purpose of producing formwork based on quantitative information related to issues such as environmental control systems, sound abatement, as well as qualitative information like non-standard variation paneling, and aesthetic composition.

title	CAD Scripting and Visual Programming Languages for Implementing Computational Design Concepts: A Comparison from a Pedagogical Point of View
source	International Journal of Architectural Computing vol. 10 - no. 1, 121-138
summary	This paper compares the use of scripting languages and visual programming languages for teaching computational design concepts to novice and advanced architecture students. Both systems are described and discussed in terms of the representation methods they use. With novice students better results were obtained with the visual programming language. However, the generative strategies used were restricted to parametric variation and the use of randomness. Scripting, on the other hand, was used by advanced students to implement rule-based generative systems. It is possible to conclude that visual languages can be very useful for making architecture students understand general programming concepts, but scripting languages are fundamental for implementing generative design systems. The paper also discusses the importance of the ability to shift between different representation methods, from more concrete to more abstract, as part of the architectural education.

summary	This paper is part of an ongoing research that analyzes the housing projects of the Dutch office MVRDV through their theoretical research and design processes. The text focuses on the use of parametric software according to two key aspects that qualify their production: research and conceptual creative potential. Since the late 1990s, the architects are positioning their practice under a strategy that combines collection, processing and interpretation of large amounts of data, what means the conversion of statistical information into concrete and inventive form. With this demand the office developed parametric software as Regionmaker, the case study presented here.

title	An Integral Approach to Structural Optimization and Fabrication
doi	https://doi.org/10.52842/conf.acadia.2012.491
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. 491-497
summary	Abstract Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure. A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase, the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive. This paper reports ongoing research efforts on the development of a cost effective methodology for the realization of TO concrete structures using HWC.

summary	Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC) (Mcgee 2011). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure (Sondergaard & Dombernowsky 2011). A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase (Xie 2010), the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive.

title	Tectonic Tessellations: A Digital Approach to Ceramic Structural Surfaces
doi	https://doi.org/10.52842/conf.acadia.2012.315

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.

title	Fabricating Sustainable Concrete Elements: A Physical Instantiation of the Marching Cubes Algorithm

summary	This paper explores how an algorithm designed to represent form can be made physical, and how this physical instantiation can be made to respond to a set of design imperatives. Specifically, the paper demonstrates how Marching Cubes (Lorensen and Cline 1987), an algorithm that extracts a polygonal mesh from a scalar field, can be used to initiate the design for a system of modular concrete armature elements that permit a large degree of variability using a small number of discrete parts. The design of these elements was developed in response to a close examination of Frank Lloyd Wright's Usonian Automatic system, an architecturally pertinent historical precedent. The fabricated results positively satisfy contemporary design criteria, including maximal formal freedom, optimal environmental performance, and minimal life-cycle costs.

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	Robotic Construction by Contour Crafting: The Case of Lunar Construction
source	International Journal of Architectural Computing vol. 10 - no. 3, 423-438
summary	Contour Crafting is a digitally controlled construction process invented by Professor Behrokh Khoshnevis that fabricates components directly from computer models, using layered fabrication technology. By obviating the need for formwork used in traditional concrete construction, CC can reduce costs and construction times significantly. The technique has great potential as a robotic form of construction reliant on relatively minimal human labor as a form of construction in relatively hazardous environments, such as the Moon with its radiation levels that can prove highly damaging. Current research funded by NASA has been exploring the potential for using CC on the Moon to build structures making use of readily available regolith that is found in great abundance on the surface of the Moon. This article offers an overview of this research and evaluates the merits of using CC on the Moon.

summary	In this work we address the fast and economical realization of complex formwork for concrete with the advantage of industrial robot arm. Under economical realization we mean reduction of production time and material effi ciency. The complex form of individual formwork parts can be in our case double curved surface of complex mesh geometry. We propose the fabrication of the formwork by straight or shaped hot wire. We illustrate on several projects different approaches to mould production, where the proposed process demonstrates itself effective. In our approach we deal with the special kinds of modularity and specific symmetry of the formwork.

title	A modelagem paramétrica e o ensino de geometria descritiva – as superfícies de Felix Candela [Parametric modeling and descriptive geometry education in architecture - Felix Candela’s surfaces]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 216-218
summary	This paper aims to discuss the possible contributions that parametric modeling environments can bring to descriptive geometry teaching process in architecture courses. The paper shows a method where models developed in Grasshopper are used to illustrate how is possible to combine computing concepts, shape generation and design references during descriptive geometry classes. In this work is used as design precedent, solutions created by the Mexican architect and mathematician Felix Candela. His concrete shells developed from hyperbolic paraboloids are recognized as important references in architecture. As was said, during the research was developed a set of models in Grasshopper. This models were created in a way to show to the students the concepts required to build an hyperbolic paraboloid.

summary	Cast Thicket is a prototypical instillation that furthers earlier research into tensile concrete molds through the use of plastic formwork and a layered structural network. Leveraging the fluid materiality of concrete and the machinability of polypropylene, Cast Thicket creates a lacy network of thin members that disperse and coalesce to address structural and spatial needs. Proposed as an application for tall concrete buildings, the research responds to the 2012 APPLIED: Research through Fabrication competition.
