title	Exploring Weaire-Phelan through Cellular Automata: A proposal for a structural variance-producing engine
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.710-714
summary	Complex forms and structures have always been highly valued in architecture, even much before the development of computers. Many architects and engineers have strived to develop structures that look very complex but at the same time are relatively simple to understand, calculate and build. A good example of this approach is the Beijing National Aquatics Centre design for the 2008 Olympic Games, also known as the Water Cube. This paper presents a proposal for a structural variance-producing engine using cellular automata (CA) techniques to produce complex structures based on Weaire-Phelan geometry. In other words, this research evaluates how generative and parametric design can be integrated with structural performance in order to enhance design flexibility and control in different stages of the design process. The method we propose was built in three groups of procedures: 1) we developed a method to generate several fits for the two Weaire-Phelan polyhedrons using CA computation techniques; 2) through the finite elements method, we codify the structural analysis outcomes to use them as inputs for the CA algorithm; 3) evaluation: we propose a framework to compare how the final outcomes deviate for the good solutions in terms of structural performance and rationalization of components. We are interested in knowing how the combination of the procedures could contribute to produce complex structures that are at the same time certain rational. The system developed allows the structural analysis of structured automatically generated by a generative system. However, some efficient solutions from the structural performance point of view do not necessarily represent a rational solution from the feasibility aspects.

summary	Robots are gaining popularity in architecture. Snøhetta has recently purchased their own industrial robot, becoming one of the first architectural offices to adopt robot technology. As more and more architects are exposed to robotic fabrication, the need for easy interoperability, integration into architectural design tools and general accessibility will increase. Architects are discovering that industrial robots are much more than kinematic machines for stacking bricks, welding or milling - they are highly multifunctional and can be used for a huge variety of tasks. However, industry standard software does not provide easy solutions for allowing direct robot control right from CAAD (Computer Aided Architectural Design) systems. In this paper we will discuss existing methods of programming industrial robots, published architectural results (Gramazio and Kohler 2008) and the design of a new user interface that allows intuitive control of parametric designs and customized robotic mass production, by integrating CAM (Computer Aided Manufacturing) functions into CAAD.

summary	The term "Parametricism" widespread mainly by Patrick Schumacher (Schumacher, 2008) is worthy of study. Developing the concept of Human Oriented Parametric Architecture, the need of implementing time as the lost parameter in current adaptive design techniques will be discussed. Morphogenetic processes ideas will be discussed through the principle of an adaptable membrane as a case study. A model implementing a unique Arduino[i] on the façade will control its patterns performance through an Artificial Neural Network that will understand the kind of scenario the building is in, activating a Genetic Algorithm that will optimize the insulation performance of the ETFE pillows. The system will work with a global behavior for façade pattern performance and with a local one for each pillow, giving the option of individual sun-shading control. Machine learning implementation will give the façade the possibility to learn from the efficacy of its decisions through time, eliminating the need of a general on-off behavior.

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

summary	The paper discusses mathematical form generation as an academic methodology to develop new approaches to architectural design. The academic design studio ‘Math objects’ investigates the relationship between complex 3d-surfaces and mathematics in order to expand the formal repertoire of architecture. It claims that the process of form generation can be seen as an autonomous entity, which is independent from an overall strategy or any a priori meaning. Architecture has always originated from a concept, eventually progressing towards a certain form. This methodology has been reversed. The paper discusses two studios undertaken in the last year, led by Daniel Baerlecken and Olaf Kobiella at the TU Braunschweig, Germany.

title	Gridshell Tectonics: Material Values Digital Parameters
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 118-125
doi	https://doi.org/10.52842/conf.acadia.2008.118
summary	This paper begins with a simple proposition: rather than mimicking the geometric structures found in nature, perhaps the most effective modes of sustainable fabrication can be found through understanding the nature of materials themselves. Material becomes a design parameter through the constraints of fabrication tools, limitations of material size, and most importantly the productive capacity of material resistance—a given material’s capacity and tendencies to take shape, rather than cutting shape out of material. ¶ Gridshell structures provide an intriguing case study to pursue this proposition. Not only is there clear precedent in the form-finding experiments of Frei Otto and the Institute for Lightweight Structures, but also the very NURBS based tools of current design practices developed from the ability of wood to bend. Taking the bent wood spline quite literally, gridshells provide a means that is at once formally expressive, structurally optimized, materially efficient, and quite simply a delight to experience. The larger motivation of this work anticipates a parametric system linking the intrinsic material values of the gridshell tectonic with extrinsic criteria such as programmatic needs and environmental response. ¶ Through an applied case study of gridshells, the play between form and material is tested out through the author’s own experimentation with gridshells and the pedagogical results of two gridshell studios. The goal of this research is to establish a give-and-take relationship between top-down formal emphasis and a bottom-up material influence.

summary	This paper presents an experience of collective digital fabrication and parametric modeling of furniture made with recycled plastic waste, inspired by natural elements of the Brazilian northeast. In addition to conventional joinery techniques, we highlight the technologies of rapid prototyping (PR) and digital fabrication (FD) (Volpato, 2007, Pupo, 2008; Pupo, 2009); as tools that promote a paradigm shift, both in the design process and in production and materialization (Kolarevic, 2005), allowing recycled plastic to have new applications. We started with a brief review of digital fabrication processes in Brazil, emphasizing collaboration in design and execution. Then, we contain the recycling of plastic and the need for actions for its best destination. Finally, we present a sustainable and collaborative design experience: the modeling and digital fabrication of furniture, entirely produced from recycled plastic, called “Banco Cabaça”.

title	CeramiSKIN: Biophilic Topological Potentials for Microscopic and Macroscopic Data in Ceramic Cladding
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 65-76
summary	CeramiSKIN is an inter-disciplinary investigation examining recursive patterns found in organic matter. Through the use of digital capture and translation techniques, these biophilic systems may serve as topological generators for structural and ornamental consequences well-suited to mass-customizable ceramic cladding systems for architecture. Digital information is acquired through laser scanning and confocal electron microscopy, then deformed using particle physics engines and parametric transformations to create a range of effects promulgated through digital fabrication techniques. This inquiry is primarily concerned with two questions: Is it possible that natural systems may be digitally captured and translated into biophilic structural forms and/or ornamental effects that may foster beneficial responses in humans? / Since natural orders eschew rigid manifold geometries in favor of compound plastic shapes, is it possible to fabricate mass-customized, large-scale biophilic ceramic cladding from organic digital data?

title	Designing (tools (for designing (tools for ...))))
source	RMIT University, Melbourne
summary	Outcomes of innovative designing are frequently described as enabling us in achieving more desirable futures. How can we design and innovate so as to enable future processes of design and innovation? To investigate this question, this thesis probes the conditions, possibilities and limitations of toolmaking for novelty and knowledge generation, or in other words, it examines designing for designing. The focus of this thesis is on the development of digital design tools that support the reconciliation of conflicting criteria centred on architectural geometry. Of particular interest are the roles of methodological approaches and of biological analogies as guides in toolmaking for design, as well as the possibility of generalising design tools beyond the contexts from which they originate. The presented investigation consists of an applied toolmaking study and a subsequent reflective analysis using second- order cybernetics as a theoretical framework. Observations made during the toolmaking study suggest that biological analogies can, in informal ways, inspire designing, including the designing of design tools. Design tools seem to enable the generation of novelty and knowledge beyond the contexts in and for which they are developed only if their users apply them in ways unanticipated by the toolmaker. Abstract The reflective analysis offers theoretical explanations for these observations based on aspects of second-order cybernetics. These aspects include the modelling of designing as a conversation, different relationships between observers (such as designers) and systems (such as designers engaged in their projects), the distinction between coded and uncoded knowledge, as well as processes underlying the production and the restriction of meaning. Initially aimed at the development of generally applicable, prescriptive digital tools for designing, the presented work results in a personal descriptive model of novelty and knowledge generation in science and design. This shift indicates a perspective change from a positivist to a relativist outlook on designing, which was accomplished over the course of the study. Investigating theory and practice of designing and of science, this study establishes an epistemological model of designing that accommodates and extends a number of theoretical concepts others have previously proposed. According to this model, both design and science generate and encode new knowledge through conversational processes, in which open-minded perception appears to be of greater innovative power than efforts to exercise control. The presented work substantiates and exemplifies radical constructivist theory of knowledge and novelty production, establishes correspondences between systems theory and design research theory and implies that mainstream scientific theories and practices are insufficient to account for and to guide innovation.

title	Information-matter hybrids: Prototypes engaging immediacy as architectural quality
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 105-110
summary	‘Immediate Architecture’ is an exploratory investigation into possibilities of immediate interactive and constructive interaction with the built environment supported by digital technologies. Aim is to realize interactive reconfigurable architectural objects that support their informational and material reconfiguration in real-time. The outcome is intended to become a synergetic amalgam of interactive architecture, parametric design environment, automated component fabrication and assembly. To this end, computational and material strategies are developed to approach the condition of immediate architecture and applied in real-world prototypes. A series of developed techniques are presented, ranging from realtime volumetric modeling, behavioral programming and meta-application protocol to streaming fabrication and dynamic components for interactive architecture.

title	Computing Different Projections of a Polyhedral Scene from a Single 2D Sketch
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 195-200
doi	https://doi.org/10.52842/conf.ecaade.2008.195
summary	This paper presents the development of a tool which is capable of compute several projections of a polyhedral scene from a single axonometric or perspective projection. This projection is hand-drawn and may be incomplete. This sketch can be rotated with a kind of trackball and the tool computes in real-time new projections. In that way the designer can choose another view from which he is able to control and complete the sketch and carry on designing. So this tool can be useful for exploring architectural forms in the early phases of the design process. Unlike others freehand sketching interfaces, the system does not operate any reconstruction in 3D. Everything is computed in a 2D world.

title	Hydrauli_City: Urban Design, Infrastructure, Ecology

doi	https://doi.org/10.52842/conf.acadia.2008.158
summary	The Hydrauli_city project was commissioned by the Harris County Flood Control District, Brays Bayou Partnership and the Rice School of Architecture to research the transformation of one of the 21 main Bayous in Houston. The project seems perfectly aligned with the theme of the issue because it examines the relationship between infrastructure, risk and urban design, and does so by attempting to leverage diverse time scales and scales of intervention into the maintenance of this infrastructure, rethinking the legacy of its top-down 20th century planning logics. Moreover, it raises key questions about new agencies and sites that may be available to architects that seek to engage the political ecologies of the contemporary metropolis. Through research on the hydraulic urbanism of Houston and through three speculative design proposals, Hydrauli_city presents research about transforming Brays Bayou. The project attempts to provide a figure for and foster the new forms of collectives and networks required to transform the urban condition of Houston without resorting to unrealistic top-down planning infrastructures. We located several scales and time-frames of operations, from micro-scaled interventions derived from ongoing maintenance of the bayous to larger scale transformations now possible due to the programs to reduce the risk of flooding in the bayou’s watershed. Hydrauli_city maps the confluences of interests and agencies invested in Brays Bayou at this crucial moment in its history, and offers proposals of bold new civic spaces for the Green Century. The project will be disseminated via an interactive website and a series of public presentations to raise awareness and spark conversation. Flood risk management is a hybrid phenomenon, at once the object of scientific knowledge, engineering practice, and political and economic forces, positioning the architect in a prime-position to intervene.

summary	This paper presents an approach for familiarizing architecture students with concepts of environmental performance in the early design stages. A design studio was run at the University of Technology Sydney by Leena Thomas and the author where students were applying building performance analysis to inform their design process from the very beginning of the semester. Students were using parametric design and evolutionary structural optimization in conjunction with environmental performance optimization. Michael Hensel and Defne Sunguroglu (Ocean North) joined the studio at half time for a workshop to investigate how processes occurring in nature can be mapped to inform the morphological design process. In spite the multitude of challenges put to the students during the semester in regard to their design methodology and techniques, they were able to produce highly performative and aesthetically pleasing design outcomes.

summary	This paper is aimed at the development of a theoretical framework that addresses practical applications of parametric design that have been observed in architectural practice. Existing theoretical frameworks are not aimed at addressing this specific use of parametric tools but do provide a set of key themes. Based on these themes a simplified structure is presented here as a means for tackling architectural design development tasks. This is then used in order to examine a case study; the parametric design tasks involved in the design development and documentation of the new Lansdowne Road Stadium in Dublin Ireland. This project was undertaken in collaboration with HOK Sport Architects. The findings from this examination are used to discuss proposals and implications for a practical framework for parametric design in architecture.

title	Knowledge Acquisition in Parametric Model Development
source	International Journal of Architectural Computing vol. 6 - no. 4, 435-451
summary	This paper addresses the development of parametric models in contemporary architectural practice. A parametric model can be regarded as a representation of a solution space and in order to structure this, a description of the problem is required. Architectural design tasks are typically ill structured, the goals may not be defined and the means unknown. Moving from an incomplete problem description to a functional parametric model is a difficult task. This paper aims to demonstrate that through a combination of knowledge acquisition and capture a parametric model can develop from an incomplete problem description. This demonstration draws on existing strands of design theory which are then used to outline a theoretical framework. This framework is then used to examine a case study of a live project and practical examples of the described theory in action are given. The practical observations are the result of a case study involving the author as a participant and observer working with HOK Sport to develop a cladding geometry solution for Lansdowne Road Stadium in Dublin.

doi	https://doi.org/10.52842/conf.caadria.2008.143
summary	The decision support system developed in this research is aimed to the conceptual scheme of project focusing on infrastructure planning and open space design in the architectural context for housing project. Alternative design sets are provided within the limitations, and possibilities to be further evaluated appropriately. This system helps architects and developers to analyze relationships of physical environment, architectural requirements and the overall of project-related factors with real-time cost estimation. Factors for cost estimation derived from the beginning to the end of project will be manipulated simultaneously. Architects and developers can use this design simulation to address the physical data with real-time cost estimation, provide alternative results, and design evaluation for overall project’s feasibility. The software of our research is not just a tool for design & planning automation in feasibility analysis. It will be an interactive decision support system for both developers and planners aspects. The system was developed by SketchUp Ruby Application Programming Interface. The results will be presented into two ways. Firstly, 2D and 3D modeling will be used for interactive visualization in design and planning of the beginning process. Subsequently, numbers and additional factors in details will be used to show relationship between architectural environment and feasibility-based information to help architects and developers collaboratively analyze the land use planning and open space design for housing project. In evaluation process, the developed software is tested with the project preceding and the future project of Bangkok area under constraints and regulations of Building Control Act of Thailand. In conclusion, this system will make effectiveness in design process and management of the construction knowledge. The decision support systems should be designed to makes explicit use of both planning analysis aspect and knowledge-based decision making.

summary	“Why do we have to change? We’ve been building buildings for years without CATIA?” Roger Norfleet, a practicing architect in his thirties poses this question to Tim Quix, a generation older and an expert in CATIA, a computer-aided design tool developed by Dassault Systemes in the early 1980’s for use by aerospace engineers. It is 2005 and CATIA has just come into use at Paul Morris Associates, the thirty-person architecture firm where Norfleet works; he is struggling with what it will mean for him, for his firm, for his profession. Computer-aided design is about creativity, but also about jurisdiction, about who controls the design process. In Architecture: The Story of Practice, Architectural theorist Dana Cuff writes that each generation of architects is educated to understand what constitutes a creative act and who in the system of their profession is empowered to use it and at what time. Creativity is socially constructed and Norfleet is coming of age as an architect in a time of technological but also social transition. He must come to terms with the increasingly complex computeraided design tools that have changed both creativity and the rules by which it can operate. In today’s practices, architects use computer-aided design software to produce threedimensional geometric models. Sometimes they use off-the-shelf commercial software like CATIA, sometimes they customize this software through plug-ins and macros, sometimes they work with software that they have themselves programmed. And yet, conforming to Larson’s ideas that they claim the higher ground by identifying with art and not with science, contemporary architects do not often use the term “simulation.” Rather, they have held onto traditional terms such as “modeling” to describe the buzz of new activity with digital technology. But whether or not they use the term, simulation is creating new architectural identities and transforming relationships among a range of design collaborators: masters and apprentices, students and teachers, technical experts and virtuoso programmers. These days, constructing an identity as an architect requires that one define oneself in relation to simulation. Case studies, primarily from two architectural firms, illustrate the transformation of traditional relationships, in particular that of master and apprentice, and the emergence of new roles, including a new professional identity, “keeper of the geometry,” defined by the fusion of person and machine. Like any profession, architecture may be seen as a system in flux. However, with their new roles and relationships, architects are learning that the fight for professional jurisdiction is increasingly for jurisdiction over simulation. Computer-aided design is changing professional patterns of production in architecture, the very way in which professionals compete with each other by making new claims to knowledge. Even today, employees at Paul Morris squabble about the role that simulation software should play in the office. Among other things, they fight about the role it should play in promotion and firm hierarchy. They bicker about the selection of new simulation software, knowing that choosing software implies greater power for those who are expert in it. Architects and their collaborators are in a continual struggle to define the creative roles that can bring them professional acceptance and greater control over design. New technologies for computer-aided design do not change this reality, they become players in it.

summary	This paper reports on the use of animation to enhance the observable range of choices in parametric rapid prototyping. Animation extends parametric rapid prototyping in three ways. First, it is used to reveal dynamically a set of possible forms from which to pick out one that may best serve a particular design project. That is, by animating the parameters that drive the geometrical model, we can visualize the continuum of alternatives that lie between specific key-framed settings of an architectural form. Second, animation can be used to pre-visualize a series of geometrical constructions for transforming a relatively raw three-dimensional form into one that satisfies the demands of a completed architectural project. Third, animation can be used to pre-visualize transformations of a given structure based on parameters set to adapt to varied conditions. In each case study, physical models were assembled through CNC fabrication.

title	Progressions in Defining the Digital Ground for Component Making
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 57-64
summary	Terms digital and computation, once accepted as emergent understandings in design, became commonly known and used in recent years. Transformation of techniques from analog to digital created a shift in the understandings as well as products of design. Digital design exploration enabled the designers’ exposure to variety and richness. Increasing number of digital tools became easily-accessible. Thus design thinking in both practice and academia was transformed. Computation, via increasing power and speed of processing, offers mass information execution. Once this power was utilized to inform the discrete pieces of design, “component making” quickly became one of the trends in architectural design. Idea of components transformed the enclosing forms of architecture into subdivision surfaces which act as fields for components to aggregate on. While there has been a great interest in creating variety via manipulation of components as individual members, the characteristics of the surfaces became overlooked via common use of parametric (UV) subdivision. This paper, with a critical look at the current component field generation techniques, focuses on alternative methods of transforming a surface into a digital ground for component aggregation. Series of studies address and deal with various pitfalls of component design and application on software-dictated UV subdivision surfaces. Studies aim to release the component design logic from being software-specific by creation and use of customized digital tools and scripts.
