summary	The project Knitectonics aims at exploring digital fabrication systems that facilitate optimized, adaptive and specific integrated architectural solutions (Male-Alemany 2010). It is inspired by the beauty of nature systems with their inherent efficiency and performance. The research explored on-site fabrication of monocoques shells, integrating skin and structure along with services and infrastructure, using a simple household technique. It thus embodies a self organized micro system of textures and a macro system of structures. This paper elaborates how the numeric aspects of a textile technique were used, first to digitally imitate the process of assembly and further exploited to develop and visualize a novel fabrication system, based on material research and technical experimentation.

summary	This paper presents a framework of study of an iterative evolution of a modular component designed in an attempt to simulate material constraints and motional response with the perspective to be multiplied into a dynamic system. The main scope of this project was to investigate the process that maps a territory of possibilities, among which lies the potential architectural solution. In order to explore this field a parametric model has been developed. The simulation of the materials nature has been embedded in the algorithm on a geometry constraint basis in an attempt to simulate the behavior of the system comprised by elements in tension and torsion. A multiplication process of the module was introduced at a following stage of the research focusing on regular tessellations and circle packing on the plane. Responsive performance has been studied on a selected specimen of the evolution given a hypothetic context scenario according to which the scale of the design was set at a façade component level. The resulting responsive permeable skin was presented as a potential design solution among the successive approximations of this algorithm. Along the course of the research the parametric tools were used not only as a medium of synchronous output visualization but also as a mechanism to simulate material properties, structural constrains, environmental data, and worked as stimuli of inspiration driving the overall design process.

title	Behavior-based Computational Design Methodologies: Integrative processes for force defined material structures
doi	https://doi.org/10.52842/conf.acadia.2011.082
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 82-89
summary	With the introduction of physics-based algorithms and modeling environments, design processes have been shifting from the representation of materiality to the simulation of approximate material descriptions. Such computational processes are based upon enacting physical and material behavior, such as gravity, drag, tension, bending, and inflation, within a generative modeling environment. What is often lacking from this strategy is an overall understanding of computational design; that information of increasing value and precision is generated through the development and iterative execution of specific principles and integrative mechanisms. The value of a physics-based modeling method as an information engine is often overlooked, though, as they are primarily utilized for developing representational diagrams or static geometry – inevitably translated to function outside of the physical bounds and parameters defined with the modeling process. The definition of computational design provides a link between process and a larger approach towards architecture – an integrative behavior-based process which develops dynamic specific architectural systems interrelated in their material, spatial, and environmental nature. This paper, focusing on material integration, describes the relation of a computational design approach and the technical framework for a behavior-based integrative process. The application is in the development of complex tension-active architectural systems. The material behavior of tensile meshes and surfaces is integrated and algorithmically calibrated to allow for complex geometries to be materialized as physical systems. Ultimately, this research proposes a computational structure by which material and other sorts of spatial or structural behaviors can be activated within a generative design environment.

title	La cámara en la animación de arquitectura. Reconsiderando “la mirada” y el régimen de mostración en el cine [The Camera in Architectural Animation. Reconsidering “The Gaze” and The Registration Regime in the Cinema]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 432-435
summary	Even though inspired by cinema, architecture animations often oversimplify filmic space, and conflate two distinct concepts: gaze, and vision. Such misinterpretation leads to overuse camera movement to present spaces as if the change of point of view would lead to communicate lived space. This article introduces such discussion in the context of the tableau vivant, a living picture, explores the use of the shot sequence and the use of non-narrative scenes.

title	Last train to trancentral: From infrastructure to ‘info’structure: a case study of embedding digital technology into existing public transport infrastructures
doi	https://doi.org/10.52842/conf.caadria.2011.335
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 335-344
summary	The research presented in this paper is an investigation into how ubiquitous computing technologies can contribute to improving the quality of existing public transport environments through the integration of responsive technologies. The paper argues that given the significant challenges associated with transport infrastructure expansion including cost, disruption, energy use, and implementation periods augmenting existing transport environments offers alternate measures to manage demand and improve the user experience. The paper proposes improving transport environments by integrating smart, or responsive, digital information into the existing physical fabric in a coherent architectural and spatial context. This approach offers an opportunity to shift away from the static nature of public transport infrastructure to the dynamic notion of public transport ‘info’structure. The research uses an architecture graduate studio as a foundation to investigate the objectives. The contribution of this paper is an investigation of ways in which digital technologies and networked communications can transform and augment public transport infrastructure, allowing new forms of intelligent, adaptive, interactive and self-aware architecture to be developed.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Sustainable Conceptual Building Design using a Cognitive System
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. 297-314.
summary	A cognitive system for conceptual building design is presented. It is based on an adaptive multi-objective evolutionary algorithm. The adaptive approach is novel and, in contrast with conventional multi-objective evolutionary algorithms, it explores the solution space effectively, while maintaining diversity among the solutions. The suitability of the approach for conceptual design of a multi-purpose building complex is demonstrated in an application. In the application, the goal of maximizing sustainability is treated by means of a model, which is established using neural computations. The approach is found to be suitable for treating the soft nature of the sustainability concept. Also, the capability of the approach to compare the performance of alternative solutions from an unbiased viewpoint, i.e. without committing a-priori to a relative importance among the performance aspects, is demonstrated.

title	Tropism-oriented generative design: Analogical models for heterogeneous goal integration
source	Master of Philosophy (MPhil) Thesis. Faculty of Architecture, Building and Planning, The University of Melbourne.
summary	Architecture often requires integration between heterogeneous objectives. Both empirical requirements and speculative aspirations inform design in ways that resist ready formalization under computerizable logic. This thesis explores the possibilities of tropism-analogy as strategy for tackling some of these diverse objectives in a generative system. The feasibility of addressing heterogeneous goals with a computerizable design system is established by reviewing the role of rule-based strategies in vernacular tradition and the possibilities of analogies in recent generative methods. Then, the concept of tropism is analysed in depth, starting from its origins to its manifestation in a broad range of disciplines. This analysis leads to the definition of tropism as a ‘process of turn’ that enables purposeful connections between a system and its environment, an invariant property that may result in different levels of adaptation. These generalized conditions are used as conceptual foundation to explore analogical connections between divergent dimensions of architectural problems, and to define a feedback-enabled generative system that uses tropism-inspired rules in tackling contrasting design objectives. This system is implemented as a proof-of-concept for the Chilean social housing program, where is used to generate façade prototypes that respond simultaneously to thermal comfort and formal expression criteria. The outcomes of this thesis suggest that tropism-analogy can be used in tackling heterogeneous façade objectives and, therefore, to define novel design methods to explore goal-integration in computer-based generative architecture systems.

title	Navigating Complex Models in Collaborative Work for (Sustainably) Integrated Design
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. 619-636.
summary	Increasingly intensive use of computational techniques such as parametric-associative modeling, algorithmic design, performance simulations and generative design in architecture, engineering and construction are leading to increasingly large and complex 3D building models which in turn require increasingly powerful techniques in order to be manipulated and interpreted effectively. Further complexities are of course due also to the multi-disciplinary nature of building projects, in which there can be significant variation and even conflict among the aims of architects, engineers and builders, as well as owners, occupants and other stakeholders in the process. Effective use of model information depends to a large extent on sense-making, which can in some ways be helped but also hindered by schemes for organizing the information contained. Common techniques such as layering, labeling (aka ‚Äòtagging‚Äô) and assignment of various other attributes to model objects have significant limitations ‚Äì especially those arising from general problems of language, ontology and standardization, as well as but distinct from issues of interoperability ‚Äì both with respect to locating the desired items in a 3D building model and also with respect to displaying the objects in informative ways which effectively assist collaborative design and decision-making. Sustainable design in particular is an area generally requiring a high level of inter-disciplinary collaboration to achieve highly integrated designs which make multiple use of the elements and systems incorporated (though integrated design may also be pursued without explicit aims of sustainability). The proposed paper describes ongoing research concerning alternatives to the currently common techniques for locating and displaying information in 3D building models in support of sense-making to promote collaborative and integrated design. These alternatives comprise on the one hand interactive geometric-content-based methods for search and classification of model objects ‚Äì as an alternative or complement to common assigned-attribute-based methods ‚Äì and on the other hand visual analytic techniques ‚Äì in contrast to existing, relatively static tabular and "physical" views ‚Äì which can help to increase the informativeness of the geometric data within the model, as well as the non-geometric data that is attached to geometric objects (e.g. as in the cases of BIM and various types of CAE performance simulations). Tests undertaken with architects and engineers in practice and academia to evaluate the proposed methods are also described. Finally conclusions are drawn regarding these methods‚Äô positive present performance and some of their shortcomings, as well as indicating directions for future research concerning the methods‚Äô refinement and extension to help 3D building models become more effective components of the design process than they are at present, both with respect to these models‚Äô present levels of complexity and especially with respect to their anticipated increasing complexity in future.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
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. 539-556.
summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

title	A study of variation of normal of polygons created by point cloud data for architectural renovation field
doi	https://doi.org/10.52842/conf.caadria.2011.321
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 321-330
summary	Acquiring current 3D space data of cities, buildings, and rooms rapidly and in detail has become indispensable. When the point cloud data of an object or space scanned by a 3D laser scanner is converted into polygons, it is an accumulation of small polygons. When object or space is a closed flat plane, it is necessary to merge small polygons to reduce the volume of data, and to convert them into one polygon. When an object or space is a closed flat plane, each normal vector of small polygons theoretically has the same angle. However, in practise, these angles are not the same. Therefore, the purpose of this study is to clarify the variation of the angle of a small polygon group that should become one polygon based on actual data. As a result of experimentation, no small polygons are converted by the point cloud data scanned with the 3D laser scanner even if the group of small polygons is a closed flat plane lying in the same plane. When the standard deviation of the extracted number of polygons is assumed to be less than 100, the variation of the angle of the normal vector is roughly 7 degrees.

title	Packing the “Chinese box”: A strategy to manage knowledge using architectural digital models
doi	https://doi.org/10.52842/conf.caadria.2011.717
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 717-726
summary	The architectural design activity has been transformed due to technological advances in building knowledge management. The research proposed is based on a three years long Ph.D. work on 3D models intended as graphical informative systems, layered according to the “Chinese box” paradigm and destined to professionals and researchers in architecture. The applied case study is referred to San Vitale’s church in Ravenna, Italy: the monument was investigated through nested digital models produced by different computer programs. Passing through evolutionary steps identified as synthesis, reduction and projection, the resulting archive lowered its Complication Ratio, a numerical value inspired by fractal’s auto-similarity, indicating a recursive modification in morphologies and contents. Models so conceived are qualified as progressive knowledge-based catalogues easily interchangeable and useful to understand how new or existing architectures work. As a result of this approach, representations obtained with surveys, historical chronicles, light analysis and acoustic simulations were composed following gradual refinements: technical data were collected running parallel to bibliographic research, enriching interactive virtual models sprung from a recursive criterion destined to increase the information enclosed into an undivided, lossless, digital archive.

summary	Design collaboration relies on cognitive tools such as analog media and digital peripheral devices, and shows the characteristics of distributed cognition. It is a social and complex activity involving multiple agents communicating and using external cognitive tools to encode, decode, and share information in the process of collaborative task completion. The systems supporting this activity should meet the ’principle of least collaboration effort’ [4] that proposes that agents in collaboration minimize their effort in presentation and acceptance of information. Yet, current collaboration systems are dispersed mixed media that is often overloaded with representations and functionality, thus preventing seam- less information sharing. Designers are required to spend extra effort collecting information using peripheral devices and in system management when sharing information. The goal of this study is to understand these overheads in infor- mation collection and sharing using peripheral devices, and to provide designers with a supportive platform to enhance collaboration using both analog and digital media. In this paper, we first review available peripheral devices such as smart pens, digital cameras, and voice recorders, as well as existing collaboration sup- porting software systems for their benefits and deficiencies in collaboration. We then present ’DiNa’, a collaboration platform that is envisioned to improve pro- ductivity and reduce redundant work by integrating peripheral devices into the collaboration workflow. We demonstrate a possible workflow using this system through several scenarios where designers collaborate in performing a series of design tasks. We hope to bring attention to the importance least collaborative effort in designing systems to support real-world collaboration.

title	Aviva Stadium: A case study in integrated parametric design
source	International Journal of Architectural Computing vol. 9 - no. 2, 187-204
summary	The nature of large complex buildings requires specialized skills across a multi-disciplinary team and high levels of collaboration and communication. By taking a parametric approach to design and construction, high quality results can be delivered on budget on time. This type of approach facilitates the opportunity for design teams to work in an iterative manner.A parametric model reduces the time associated with complex design changes while providing a centralized method for coordinating communication. In this paper the recently completed Aviva Stadium is used to illustrate the ways in which these benefits manifest themselves on built work.The authors identify the moments in the design and construction process that truly justify the effort in implementing a parametric approach. By approaching design in this way a “design conversation” can take place between parties involved, resulting in a better building.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
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. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

summary	In contrast to such structurally pure models, the power of computation has opened possibilities for at once muddying and synthesizing geometry, structure and material performance. Where the earlier twentieth century experiments employed a more or less uniform tectonic based on symmetrical structural diagrams, contemporary analysis and design techniques can efficiently adapt a material system to address variable, localized, and non-symmetrical loading conditions. This has resulted in projects characterized by non-optimized structural forms that register the impacts of geometry on material behavior with a deviated tectonic system.

summary	Over the decade of the aughts, architectural discourse has charted a new course, and in the wake of the digital effect on mainstream architectural thinking, we find ourselves in a great age of exploration. Research in digital fabrication has moved from the general to the specific, in that it aims to focus efforts related to technological impact on particular cases and variable parameters which contribute to even larger ideas, such as manufacturing, the social impact, sustainable practices, etc. Specific work on building components, coupled with a pragmatic rigor about durability, strength, and production have provided concrete examples of work that spin out of these design-through-production investigations. To be certain, each new design-through-production project explores unique territory and contributes to the knowledge map by adding to a matrix of possible applications. Still, we align our work with the age-old discipline of architectural thinking, while privileging “Making, Materials, Performance, Form, and Function.” Indeed, form is informed by performance! The principles that govern the human decision-making, in light of this new kind of digitally generated work have yet to be clearly articulated, but techniques and methods have expanded to create new opportunities for making architecture. In fact, research has tended to be less about framing the new principles for making digital architecture and more about adding specific cases to the knowledge base, as each new project helps to define the collective body.

title	Irregular Vertex Editing and Pattern Design on Mesh
doi	https://doi.org/10.52842/conf.acadia.2011.278
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 278-283
summary	This paper introduces an innovative computational design tool used to edit architectural geometry by addressing the problem of irregular vertices. An irregular vertex is a special kind of vertex which is connected with fewer or greater less or more edges than regular vertices on a mesh object. Irregular vertices create problems with further surface rationalization, as well as structural analysis and constructability of the surface. Geometry created using other tools can also be remeshed upon import. Using the developed tool, the user is able to identify irregular vertices, interactively change the type, and then move or remove these irregular vertices. Additionally, a computational tool to make various design patterns on the mesh after the topology has been edited is also developed. The workflow is illustrated step by step in the pipeline. The advantages and disadvantages of editing mesh topology on architectural geometry design including the limitations are discussed at the end.

summary	Concepts such as integrated practice and integrated design are increasingly seen in architecture as promising paradigms for a much needed (and long overdue) change in the building industry. What is usually meant by these terms is a multidisciplinary, collaborative approach to design in which various participants from the building industry – architects, engineers, contractors, and fabricators – participate jointly from the earliest stages of design, fluidly crossing the conventional disciplinary and professional boundaries to deliver an innovative or simply better and less costly product at the end.

title	A is B, displacement: Exploring linking patterns within metaphor in the design process
doi	https://doi.org/10.52842/conf.caadria.2011.663

summary	Design educators often apply metaphor as a teaching tool to help novice designers in their design process. Richards(1936) defines metaphor as the form “A is B”. The most important operation in metaphor is displacement—the linking process of moving A to B. Linking ideas is the key mechanism in the design process. By linking ideas, a graph-like knowledge represents the individual memories with the nodes and arcs that are the ideas and the links between ideas respectively. Such linking knowledge provides an interesting way to understand the operation of displacement within metaphor. This research applies a computational tool (called DIM) to produce a graph-like knowledge. Protocol analysis is then used to understand how designers organize ideas. The objective of this research was to explore the linking patterns of idea displacement within metaphor in the design process.
