title	Analysis model for incremental precision along design stages
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. 19-18

summary	With current energy analysis tools, architects and engineers cannot rely on the results of energy analyses because they do not report their level of precision. In addition, current tools also do not deliver feedback in real time. Thus, this research addresses the challenge of obtaining feedback in real-time while gradually increasing precision along design stages. For this purpose, this study merges parametric modelling (PM) technologies and the performance-based design (PBD) paradigm into a general design model. The model is based on a parametric and an energy analysis model that share the parameters of a building. The modular architecture of the model involves four main function types: an input processor, optional analysis functions embedding different calculation methods, a decision-maker, and a report generator function. For every step of the design evolution, the decisionmaker function generates a specific tree of analysis functions.

summary	Architectural contexts present both resources and restrictions from local spatial environment, such as factors of sunlight, landscape, line of sight, terrain and etc. They play important roles in architectural design. Following the traditional methods, it takes the architects lots of time to analyse the relative relationships. This paper takes terrain and sunlight into consideration to illustrate how to employ generative methods at the early stage of architectural design.

title	Using 3D Design Software, BIM and Game Engines for Architectural Historical Reconstruction
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. 493-509.
summary	The use of digital tools has become a tremendous aid in the creation of digital, historical reconstructions of architectural projects. Regular visualization techniques have been used for quite some time and they still pose interesting approaches, such as following cinematic techniques [1]. While common visualizations focus on pre-rendered graphics, it is possible to apply Game Engines [2] for real-time architectural visualization, as witnessed by [3] and [4]. In the course of our teaching and research efforts, we have collected experience with several visualization and modeling techniques, including the use of gaming engines. While the modeling of qualitative geometry for use in regular visualization already poses an elaborate effort, the preparation of models for different uses is often not trivial. Most modeling systems only support the creation of models for a single amount of detail, whereas an optimized model for a real-time system will have fairly different constraints when compared to non-real-time models for photorealistic rendering and animation. The use of parametric methods is one usable approach to tackle this complexity, as illustrated in [4]. One of the major advantages of using parametric approaches lies precisely in the possibility of using a single model to generate different geometry with control over the amount of detail. We explicitly tackle this in a Building Information Modeling (BIM) context, as to support much more than purely 3D geometry and visualization purposes. An integrated approach allows the same model to be used for technical drawings in 2D and an optimized 3D model in varying levels of detail for different visualization purposes. However, while most Building Information Modeling applications are targeted to current architectural practice, they seldom provide sufficient content for the recreation of historical models. This thus requires an extensive library of parametric, custom objects to be used and re-used for historically accurate models, which can serve multiple purposes. Finally, the approach towards the historical resources also poses interpretation problems, which we tackled using a reasonably straightforward set up of an information database, collecting facts and accuracies. This helps in the visualization of color-coded 3D models, depicting the accuracy of the model, which is a valuable graphical approach to discuss and communicate information about the historical study in an appealing format. This article will present the results of different reconstruction case studies, using a variety of design applications and discuss the inherent complexity and limitations in the process of translating an active, evolving model into an environment suitable for use in a real-time system. Especially workflow issues are identified, as the translation of the model into the game engine should be repeated several times, when the model is further refined and adapted. This used to involve a large amount of repetitive work, but the current crop of game engines have much better approaches to manage the updating of the geometry.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

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 Swell Project: Between Parametrics and Fabrication
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
doi	https://doi.org/10.52842/conf.acadia.2011.x.r0r
summary	As a case study, Swell serves as: 1) an investigation into architectural ornamentation using a contemporary framework, as directed through specific modes of research, 2) a study in fabrication materials and methods, especially through the realization of form, and 3) as a pedagogical tool, loosely assembled through real and virtual space. This essay will focus mainly on the fabrication methods in terms of why and the pedagogical research initiatives and reactions that went into the design of Swell. The project was conceived through a summer studio which was formed to investigate tools and methods available at the Texas A&M Architecture Ranch and to further the local pedagogical direction toward fabrication in architectural design at Texas A&M University as a whole. That is to say, there was no specific agenda toward parametrics, form, research, technology, or the like. At the same time, as the research continued, certain decisions were cast in terms of technology, sensibility, site, etc. informed by research, iterative processes, or parametric evaluation that ultimately formed the project as it exists today.

As a case study the ICD/ITKE research pavilion’s information modeling process is depicted: how form-finding experiments guided the development of various models that synthesize data for design, simulation, analysis and fabrication. The paper explains the integration of relevant material information into generative computational design processes and concludes by comparing the resultant data models with a scan of the built prototype.

title	Digital Materiallurgy: On the productive force of deep codes and vital matter
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. 90-97
doi	https://doi.org/10.52842/conf.acadia.2011.090
summary	This paper expands the discourse surrounding digital forms of making by scrutinizing the role of materials within computation, ultimately proposing a speculative working model that charts new territory. The growing importance of materials within technological research makes this an appropriate time to consider the nuance of their role within it. Currently, material innovation is happening along two central tracks: the customized cutting, sculpting, and forming of conventional materials with Computer Numerically Controlled (CNC) fabrication equipment and the development of new materials through innovations in material science. Both tracks rely on a limited set of material protocols which enable process-based control and eliminate the intrusion of any unpredictable material variable. Although efficient, such an approach limits architecture’s ability to procure novel material engagements. A few designers are developing an alternative model where computational codes are coupled with eccentric materials to produce unusual results. Digital materiallurgy, as I have called it, is part technique and part attitude; it relies on intentionally ceding limited design control to unpredictable matter—thus capitalizing on matter’s innate ability to produce unexpected formal and material complexity. Digital materiallurgy identifies the intersection of computation and eccentric materiality as a departure point for architectural innovation. By purposefully inserting material heterogeneity and inconsistency into computational means and methods, this work pries apart the apparently seamless relationship between digital design and physical production. By blurring the distinction between physical material and digital form, this work offers an integrated aesthetic experience, one that fetishizes neither the virtual nor the vintage but fuses both into a richer, wilder present.

summary	The paper presents performance oriented approaches to digital form finding which stems from the lines of research on performance and morphogenesis in architectural design. The main contribution to the earlier research is threefold; it examines the potential of the presented design processes to integrate interdisciplinary approach based on the use of simulation tools by architects or direct data exchange between simulation tools and design. Secondly, it explores new methods to generate initial architectural form based on performance information that apply to both building scale and urban scale, and lastly, it develops the theoretical framework on the ramifications of employing simulation technology and techniques in architectural design.

title	Architecture = Computer‚ from Computational to Computing Environments
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. 217-232.
summary	Drawing on architecture, urban digital media, engineering, IT and interaction design, the research presented in this paper outlines a possible shift from architecture designed through computation (any type of process, algorithm or measurement done in a computational matter) towards architecture capable of computing (developing, using and improving computer technology, computer hardware and software as a space-defining element). The research is driven by recent developments in four fields, as follows: (a) Architecture in its recent development has shifted from a planar box, as was the ideal in the modernist movement, towards complex and non-standard forms. (b) The design concepts of non-standard surfaces have been adopted into media facades and media architecture by liberating the pixel from its planar position on a screen [1]. (c) Advancements in pervasive computing applications are now able both to receive information from the environment in which they are used and to detect other devices that enter this environment [2]. (d) Developments in advanced autonomous systems such as Human Computer Interaction (HCI) or Human Robot Interaction (HRI), have produced intelligent systems capable of observing human cues and using these cues as the basis for intelligent decision-making [3]. Media fa_ßade developments work in the direction of the above-mentioned four fields, but often come with limitations in architectural integration; they need additional components to interact with their environment and their interactions are both often limited to visual interactions and require the user to act first. The researched system, Polymedia Pixel [4] discussed in this paper, can overcome these limitations and fulfil the need for a space-defining material capable of computing, thus enabling a shift from architecture designed by computation towards architecture capable of active computing. The Polymedia Pixel architecture merges digital technology with ubiquitous computing. This allows the built environment and its relation with digital technology to develop from (a) architecture being represented by computer to (b) computation being used to develop architecture and then further to where (c) architecture and the space-defining objects have computing attributes. Hence the study presented aims to consider and answer this key question: ‚ÄòWhen building components with computing capacity can define space and function as a computer at the same time, what are the constraints for the building components and what are the possible advantages for the built environment?‚Äô The conceptual framework, design and methods used in this research combine three fields: (a) hardware (architecture and design, electronic engineering) (b) software (content design and IT) and (c) interaction design (HCI and HRI). Architecture and urban design determinates the field of application. Media architecture and computer science provide the technological foundation, while the field of interaction design defines the methodology to link space and computing [5]. The conceptual starting point is to rethink the application of computers in architecture and, if architecture is capable of computing, what kind of methodology and structure would find an answer to the above core research question, and what are the implications of the question itself? The case study discusses opportunities for applying the Polymedia Pixel as an architectural component by testing it on: (a) constraint testing ‚Äì applying computational design methodologies to design space (b) singular testing - discussing the advantages for an individual building, and (c) plural testing ‚Äì investigating the potential for an urban context. The research aims to contribute to the field of knowledge through presenting first steps of a System < - > System mode where buildings can possibly watch and monitor each other, additional to the four primary interactive modes of operation. This investigation, its proposed hypothesis, methodology, implications, significance and evaluation are presented in the paper.

title	Tree facades: Generative modelling with an axial branch rewriting system
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. 175-184
doi	https://doi.org/10.52842/conf.caadria.2011.175
summary	The methods and algorithms of generative modelling can be improved when representing organic structures by the study of computational models of natural processes and their application to architectural design. In this paper, we present a study of the generation of branching structures and their application to the development of façade support systems. We investigate two types of branching structures, a recursive bifurcation model and an axial tree based L-system for the generation of façades. The aim of the paper is to capture not only the form but also the underlying principles of biomimicry found in branching. This is then tested, by their application to develop experimental façade support systems. The developed algorithms implement parametric variations for façade generation based on natural tree-like branching. The benefits of such a model are: ease of structural optimization, variations of support and digital fabrication of façade components.

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.

summary	Borne from the complex negotiation between liquid mass and tensile constraint, flexible formwork castings are resonant with material energy. Hard as stone, yet visually supple and fluid, the pre-cast architectural assemblies produced using flexible formwork techniques suggest integrative design strategies that acknowledge the intricate associations between form, fabrication, and material behavior. This tripartite synthesis between geometry, making, and performance has emerged as one of the central themes of contemporary architecture and engineering. Borrowing ideas of morphology from biology and physics, 20th century architectural innovators such as Antoni Gaudi and Frei Otto built a legacy of material practice that incorporated methods of making with material and geometric logics. The emergent effects (and affects) produced through these highly integrative practices serve as the basis of much of the research and design at Matsys. Building on the flexible formwork research of Miguel Fisac in the 1970s, the P_Wall series by Matsys explores the use of digital tools in the generation and fabrication of these bodies in formation.

title	Visualisation of Uncertainty in Archaeological Reconstructions
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 45-52
summary	Archaeological research begins with historical remains and ends with hypotheses that base on analogies and probabilities. Well conserved remains allow a more fundamental reconstruction even in three dimensions whereas sometimes there are only vague contours. Therefore the visualisation of e.g. an ancient city only partly relies on research, other parts can be entirely hypothetic. Static models are incapable of representing both at the same time: the hypothesis and the uncertainty implied. In most cases the uncertainty varies within a hypothesis, parts of a city or building are more likely than others, some hypotheses even contradict each other. Grades of uncertainty require an adequate visual reprentation in order to visually explain hypothesis and uncertainty. In the field of archaeology an adequate method has not been established yet. In this work we explore the application of methods of architectural visualisation in order to express scientific uncertainty gradually between reconstruction and hypothesis. During the last two years we worked on several archaeological sites with emphasis on the ancient Pergamon.

title	Parametric materiality: Material properties as catalyst for design
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. 165-174

summary	Sustainability issues are increasingly taking more prominent positions in the hierarchy of design decisions. The combination of linked digital analysis and parametric design has emerged as an integrated method of assimilating performative characteristics into design. As these “informed design” methods evolve there is an increasing ability for architectural geometry to be rationalized, whether this is for reasons of constructive optimization, or environmental and economic justification. But the macro scale approach to geometry in design is only one mediator of the designs impact in its surroundings. This paper discusses what happens when designers fundamentally question the role of materials in design, and specifically what happens when “new” materials and their performative characteristics can be modelled and implemented into the digital design decision process. These approaches are showcased in “proof of concept” projects that have been developed using digital design and production technologies, in collaboration with material scientists and industry.

title	BIM: configurações e desdobramentos para implementação prática e ensino de arquitetura [BIM: configurations and unfoldings for implementation in practice and architectural education]

summary	This paper reports on the initial findings of a long term case study. It focuses on the BIM implementation efforts for Brazilian public firms that are responsible for the design, construction and management of buildings, infrastructure and urban spaces. It was postulated that BIM implementation could bring to Brazilian public institutions benefits similar to the ones achieved in the US, yet at a different cost structure. Research follows a mixed methods approach using focus groups and quasi experiments. Results describe obstacles encountered, benefits realized, and process changes expected that result from Brazilian socio-cultural context applied to public institutions.

title	Computational landscape design with the seed scattering system: A case study in the Sony forest project
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. 49-58
summary	This paper proposes a computational landscape design method, called the seeds scattering system (SS system), which enables us to manage various environmental parameters in design processes, to create the ‘natural forest’ in urban environments. First, this paper discusses the drawbacks of the conventional methods for landscape design. Second, the paper outlines the components of the SS system together with the design process of the SONY forest project in Tokyo, and shows its advantages, including broad applicability to conceptual design, and capability of environmental simulations and spatial optimizations. Last, the paper summarizes the effectiveness of the SS system. By managing fundamental rules behind geometries in forest growth processes, the SS system showed us capability for constructing interactive relationships between design and their surrounding environments to produce design inherent in its site.

title	Data flow and processing in the computational fractal analysis method
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. 493-502

summary	One of the few quantitative methods available for the consistent analysis of architectural form is the ‘box-counting’ approach to determining the approximate fractal dimension of a plan or elevation. In its computational form this method has been used to analyze the plans and facades of a wide range of buildings. The data points produced are synthesized by the software into a series of fractal dimension (D) values that are in turn compiled in various ways to produce a series of composite results describing a complete building. Once this process is complete the data may be coded with additional information producing a set of mathematical results that describe the form of a building. This paper offers the first complete description of this important analytical process from the point of view of information flow, algorithmic operations, review options and data magnitude. No previous paper has detailed the full scope of the data used in the computational method, or the way in which various stages produce different types of outcomes. The purpose of this paper is to elucidate the way in which this particular computational method, drawing its inspiration from the complexity in natural systems, may be used to process different types of information and produce various forms of quantitative data to support architectural design and analysis.

title	Usability as a Key Quality Characteristic for Developing CAAD Tools and Environments
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.269-278

summary	In this paper, we will stress the importance of usability as a key quality characteristic for the Computer Aided Architectural Design (CAAD) software prototypes. We claim that usability evaluation practices can assist the integration of human factors and the accommodation of local differences. These practices are not solely limited to interface tests, but they can also provide valuable information on the possible added values of CAAD software prototypes, increase the overall product quality and thus contribute to the sustainable development of the CAAD research field. In this context, we aim to initiate a constructive discussion on this topic by reviewing various usability frameworks and highlighting possible opportunities and challenges of applicable evaluation methods. Consequent to this discussion, we will elaborate on our recent findings relating to the reliability and effectiveness of particular evaluation methods applied to a web-based geographic virtual environment prototype. In conclusion, we will introduce a new “design usability” framework that is suitable for CAAD software development; which suggests a variety of design usability quality characteristics, cost-effective evaluation methods and possible influence factors in the evaluation process.
