title	Bio-shell (Biodegradable vacuum-formed modularized shelter)
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	This poster demonstrates how digitally fabricated vacuum-formed components can provide a new type of lightweight construction applicable to architecture. Surface-active systems such as a thin-shell concrete domes are some of the most material-efficient structures. Despite their efficiency few have been constructed recently due to necessary extensive labor cost. However, the growing concern for a worldwide shortage of natural resources and rising material costs, suggests that we reconsider the use of efficient structures, such as surface-active systems. Vacuum formed plastics mainly used in industrial design have strong merit based on their fast and low-cost mass production. Together with the recent emergence of digital fabrication technologies, the vacuum forming process is becoming an attractive fabrication technique for new and innovative lightweight structures.

title	Using Virtual Worlds as Collaborative Environments for Innovation and Design: Lessons Learned and Observations from Case Studies in Architectural Projects
doi	https://doi.org/10.52842/conf.ecaade.2009.523
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 523-532
summary	In this paper we discuss observations and lessons learned in conducting architectural design projects in virtual worlds. By integrating a community of users in virtual worlds into a collaborative architectural design process, organisations can tap the community’s creativity and intelligence through immersive technology. The paper provides an overview of the latest advances of information and communication technologies in immersive virtual environments and discusses some of the observations and lessons learned which should be taken into account in developing collaboration models for such activities. Here we propose four modes of collaboration, based on the choices for degree of openness and governance structure, which are illustrated by four case studies.

title	Beyond Representation: Real Time Form Finding of Tensegrity Structures with 3d ‘Compressed’ Components
doi	https://doi.org/10.52842/conf.ecaade.2009.021
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 21-30
summary	Tensegrity structures are of interest to architecture and engineering as a practical means to explore lightweight and rapidly deployable modular structures that have a high degree of geometric freedom and formal potency. The notion of tensegrity structures with 3D ‘compressed’ components is introduced and their feasibility is demonstrated through selected physical models. Attempts to further explore the architectural potential of tensegrity structures within a computational environment have proven difficult, as they are statically indeterminate and require form finding procedures to “find a geometry compatible with a self-stress state” (Motro 2002). An overview of tensegrity ‘capable’ software that can be used for architectural design is followed by a discussion that introduces an additional computational method based on particle-spring systems. This approach enables real time manipulation of tensegrity networks. Two projects that utilize this unique tool are described.

title	Cognition Model in Conceptual Designing
doi	https://doi.org/10.52842/conf.caadria.2009.771
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 771-780
summary	Both design researchers and cognitive scientists have developed various process models to study human creative behaviour in design. The models developed are often based on observations of design processes and analysis of design protocols. This research paper reports the-stateof- the-art in the area of cognition models that present design activities in conceptual designing. The research paper investigates the approaches of these cognition models. A new approach of a cognition activity model in conceptual designing is proposed. The new approach used in the introduced model takes into the account factors and activities that are related to the external environment of design (design medium). The external environment has an important role in the cognition activities and the evaluation process in a way that can hardly be ignored or neglected. The presented model of cognition activities in conceptual designing highlights two main factors employed in all the iteration loops of the model, namely: media use and representation. Case studies of architecture students’ designs have been analyzed. The analysis of these case studies helped in forming the proposed model. Various results have been concluded and reported.

summary	The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

title	Architectural Abstraction and Representation: The embodied familiarity of digital space
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 305-321
summary	This paper argues that familiarity is the tool that enables the understanding of space abstraction and representation. Familiarity in this context is independent from embodied interaction, and is crudely based on the connection between the various similar images of space; in this particular case, virtual space. Our investigation into the nature of human interaction with space, its abstraction and its representation is based on the critical contrast between the outcomes of interaction with two virtual versions of a physical reality; the first version is a non-linear interactive graphical abstraction of the space where no assertions or indicators are given as to whether or not there is a relationship between the abstraction and its physical reality, whereas the second is a none-linear interactive 3D virtual environment clearly representing the physical space in question. The paper utilises qualitative methods of investigation in order to gain an insight into human embodied experience in space, its abstraction and representation.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The paper describes exploratory work in the design, construction, and habitation of a virtual structure (VS) nested within an Internet-based multi-user environment and serving a geographically distributed collective of architecture students and faculty. In addition to a discourse on the design and implementation parameters that were used, the paper seeks to provide findings that make reference to the quality of teaching/learning experience of users and the effectiveness of the interaction among users while working on a common architectural design project. This experience will further contribute to the knowledge base that will be needed in the design of virtual architecture.

title	Gis in Architectural Education: Design as a place-making process
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 393-407
summary	Responsiveness to site conditions and environment is one of the axioms of architectural design. However, most students’ design is made in a non-geo-coordinated cyberspace through CAAD design and thus leading to “flying” proposals” that are not attached to the context. GIS teaches students in architecture to initially refer to real locations as the space in which they design is geo-coordinated and provides the wider context of the project. Along the design process, the project surroundings from macro scale; that is the globe, to the micro-scale that is reflected in the existing buildings, the road network and the topography are constantly present. At the end stage, the project is seen not as a free standing building but rather as an integral part in a real place on Earth. The 3-D urban visualization gives the possibility of evaluating the degree of success of place-making and the fitness of the project to its context. The aim of the paper is to present how a GIS course can support CAAD and improve the architectural design process as well as the quality of the design output towards a contextual architecture. The paper is based on the experience of the author who is architects and urban planner, in teaching design studios and Urban Planning based on GIS as an elective course to graduating students in architecture at the University of Bahrain. It presents an alternative method that is called Permanent Presence of the Real World PPRW.

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.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 314-327
summary	This paper explores an interdisciplinary design approach for coupling semi-automated applications with tangible user interfaces. It describes communication methods based on parameters and diagrams, between computer scientists and urban, architectural professionals and the matching abilities to give meaning to the various parts and elements of the system. By means of the development of two rule based applications it exploits different degrees of automation and kinds of feedback possibilities and its impact on discourse and decision making. It discusses design methods for interactive urban planning applications, which integrate the different requirements and benefits from both disciplines.

source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 285-294
summary	Schools and teachers increasingly apply Online Learning Environments for teaching and course management. In many cases, an existing platform is used to support the curriculum. At the K.U. Leuven in Belgium a campus-wide platform is provided, using a commercial Content Management System. At the same time, the Design and Building Methodology research group at the Department of Architecture, Urbanism and Planning developed a custom portal to organize Computer Aided Architectural Design courses and seminars. Integration of this portal into the university system was rather disappointing, since much of the flexibility and customizability was lost, without any chance of filling in the gaps. This article discusses the possibilities and limitations of existing web-based systems to support Computer Aided Architectural Design teaching and reports on our own experiences from the last decade. A comparison of selected systems is juxtaposed with the requirements derived from these experiences.

title	Digital Materiality: emergent computational fabrication
source	Performative Ecologies in the Built Environment: Sustainability Research Accross Disciplines: 43rd Annual Conference of the Australian and New Zealand Architectural Science Association
summary	Fundamentally architecture is a material-based practice that implies that making and the close engagement of materiality is intrinsic to design process. With the rapid uptake of new computational tools and fabrication techniques by the architectural profession there is potential for the connection between architecture and materiality to be diminished. Innovative digital technologies are redefining the relationship between design and construction encoding in the process new ways of thinking about architecture. A new archetype of sustainable architectural process is emerging, often cited as Digital Materialism. Advanced computational processes are moving digital toolsets away from a representational mode towards being integral to the design process. These methods are allowing complex design variables (material, fabrication, environment, etc.) to be interplayed within the design process, allowing an active relationship between performative criteria and design sustainability to be embedded within design methodology.

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	Algorithmic Form Generation of a Radiolarian Pavilion
source	International Journal of Architectural Computing vol. 7 - no. 4, 677-688
summary	This paper describes the design stage of an on-going research project for the construction of a pavilion that mimics the bone structures of Radiolarians. In the process, several constructive and generative algorithms are developed, together with geometric and trigonometric functions, all implemented in RhinoScript and a math plug-in for the NURBS modeler Rhinoceros. There has been considerable emphasis on the generation of the Radiolarian cell that is tessellated along a stereographic surface with a honeycomb-based algorithm. It combines design strategies from biomimetics, mathematical functions, generative scripting, process automation and versioning, all integrated into an algorithmic methodology for creating a non-standard structure, capable of being manufactured with CNC technology, and doing so, setting a precedent in the academic and professional environment in which it will be located.

summary	Process/product complexity is at present an unavoidable component of present building design approach that affects building product’s quality. To overcome this problem, effective collaboration is required among all the actors involved in the design process. Data and information exchange is not sufficient to guarantee mutual understanding; to support effective collaboration among actors; it is required a proper knowledge formalization and management. This paper reports on an innovative structure for knowledge modeling in cross-disciplinary building design, that has been formalized in a general template. The proposed Knowledge Model has been, at present, implemented by means of available ontology editors and is going to be used into teaching courses to check its efficiency in collaborative building design classes.

summary	The present research is an exploratory study about medium-range 3D-scanning technologies for architectural applications. Its purpose was to gather information that will subside the future acquisition of a 3D-scanning equipment for the Laboratory for Automation and Prototyping for Architecture and Construction, LAPAC, at the University of Campinas (UNICAMP). In order to test some of these technologies, some experiments were carried out. Museum sculptures were digitized and the results were 3D-printed. Preliminary results show that accurate technologies are still very expensive, but there are some alternative, more accessible technologies, based on photogrammetry, which can lead to fairly good results.

source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 567-576
summary	Design is an iterative exploration process that will invoke many fragmented information with continuous iteration. While fragmented, implicit information lay among these fragmented pieces has shown more potential to achieve some goals that we might skip during the decisionmaking. These potential design goals named implicit intended solution are the problem spaces we want to explore in this research. Therefore, the continuous thinking/operation process cross these fragmented design decision might show some insights for discovering implicit intended solutions. This is a two-fold problem, without exploration and its continuous iteration characteristics, these solutions might not even be found or possible found. Therefore, in this paper we have conducted a research based on visualizing these implicit intended solutions as well the exploration process for finding them.

summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

summary	Pedestrian’s movements and spatial cognition in urban environments are main issues for urban designers in urban spatial planning and analysis. This paper aims to study interactions between a behavioural model of pedestrians and urban spaces. The pedestrians can be represented by an agent program, and behavioural reactions of walking agents under different stimulus can be further simulated. Thus, this study suggests that, a correlation study on pedestrian behaviours and spatial environments become the criterion for urban designers in order to help them create better flows.
