Forgues, Daniel, and Yoann Eugenie. "A "collaboratory" as a new context for transforming practices through technology." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 37-50. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Building design is today a major social, economic and environmental challenge. Design is also a source of innovation and an important economic driving force that requires the collaboration of professionals from various fields of expertise. But the traditional linear approach in design has shown its limits, and it often leads to non optimal design solutions and buildings with inadequate performances. This paper aims to validate a computer supported collaborative workspace that facilitates the participation, in an integrated approach, of the various members of a construction project team. The goal of the research is to be part of the evolution of work practices in design.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 786-799. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. The use of a design tool materializing the performative design concept is presented. The association of parametric design with lighting intentions leads to a light-based parametric design approach. This approach have been implemented through an inverse natural lighting model which is intended to aid the daylight design (windows, shading devices or others) in the early stages of architectural design. We show this model can be used in a performative design approach to define the transparency property through a case study: the dome of the Louvre Abu Dhabi museum by Ateliers Jean Nouvel.
Moloney, Jules. "A morphology of pattern for kinetic facades." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 200-213. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Kinetic facades offer new compositional opportunities based on the design of patterns of movement. There is the capacity for novel form, but minimal knowledge in the design of kinetics. As a way forward, this research addresses two questions ? what is the range of kinetic patterns, and what nomenclature may robustly describe pattern range? Results from a series of scripted animations utilizing a range of techniques are analyzed, and from this a set of terms for describing the morphology of kinetic pattern is developed. Kinetics is conceived as state change: the terms used to describe states are wave, fold, and field, a full range of patterns can be described as variants of these three simple states, or as intermediate or compound state transitions.
Thorpe, Graham, and Sam Kashuk. "A Syncretization of Architecture, Engineering and Science:The use of CAD technology as a pedagogical tool in the teaching of environmentally sustainable design." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Energy consumption in buildings is responsible for about 40% of Australiais greenhouse gas emissions. It is quite feasible that the energy consumption in buildings can be halved, but energy performance analysis must be integral to the entire design process. This imperative has led the authors to propose that architecture, engineering and science should be syncretized in the design process. This syncretization shares some features of the rhizomatic approach introduced by Deleuze and Guattari (2007). In rhizomatic systems all points can be, and should be connected. A rhizome can be considered as a space that develops, not from a point but from milieux. In the expansion of a rhizome, elements of the system do not follow tracings of other elements but they form a map of new vistas. Likewise, a syncretic approach is oblivious to the traditional boundaries between architecture, engineering and science. Syncretization has the potential to enrich the intellectual lives of architects, scientists and engineers, and it would have profoundly beneficial performative benefits. 
Chen, Chiung-Hui. "An agent-based street simulator." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 833-846. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper aims to study interactions between a behavioural model of pedestrians and urban spaces, and regards micro-scale urban spaces as its target. This paper suggests constructing and analyzing a pedestrian behavioural model using the “Attention Theory” and introducing the rules and attributes of agent behaviour oriented simulation. Based on the validation of actual street cases, the findings show that the pedestrians can be represented by an agent program, and behavioural reactions of walking agents under different stimulus can be further simulated.
Janssen, Patrick. "An evolutionary system for design exploration." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 259-272. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper reports on the development of a multi-objective evolutionary developmental design environment, called EDDE. The goal of the system is to make it easier for designers to use evolutionary techniques to explore design possibilities. The system consists of a generic evolutionary core into which a set of design specific scripts need to be plugged in. The system uses a web based client-server architecture that can either be run on a single computer or on multiple computers in parallel. Initial experiments have shown the system to be effective in evolving designs.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 273-287. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009.

This paper presents a pilot study to analyze the role of problem solving expertise (PSE) and computational tool proficiency (CTP) of expert and novice architects in the ideation process within a distributed cognition environment. To analyze PSE, we studied the frequency of occurrence of unique problem solving tasks per limited commitment mode (LCM) revisit. We also devised a quantitative measure for analyzing CTP based on the frequency of unique and normally distributed modelling activities per design process flows for a parametric modelling tool. In our study that involved freehand sketching and parametric modelling as two external representations used in the ideation process, we concluded that expert architects have higher levels of both PSE and CTP than novices.

"Architectural design analysis, historical reconstruction and structured archival using 3D models: Techniques, methodology and long term preservation of digital models." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 119-132. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. With the increased usage of 3D modelling, visualization, simulation and Building Information Modelling, architects produce 3D models, both for new designs and for historic reconstructions. However, these models are seldom shared to transfer structured information about the project. Even if they are exchanged, they are often not usable outside of their original design application. Additionally, digital archives with architectural content can not easily provide structured information about these 3D models, limiting their usefulness. This article discusses an approach to provide better structured models, using a combination of a sound methodology, the application of open file formats and additional metadata creation.
Wikberg, Fredrik, and Ekholm Anders. "Architectural objects and systems building." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 515-529. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. In this paper we explore the concept of “architectural objecti as a representation of a real “situationi involving people, behaviour, experience and environment. The purpose is to define a selection of possible configurable architectural objects that reflect the variability of situations possible to achieve using an industrialized building system. The paper presents a theoretical foundation for organizing architectural objects in a level order of design in different levels. It is applied to configure building projects in a company with off site production of volume elements, and proposes how these objects could be developed into architectural objects.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 875-886. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. In this paper we present a new parametric approach based on environmental constraints, in order to generate digital models of architectural shape, directly within a three dimensional geo-referenced environment. Those constraints may be regarded as force fields with a specific spatial dimension. The system allows user, through implementation of specific generative procedures, to manage interactive architectural design processes. The designer is able to explore all possible infinite scenarios and the various possible design alternatives, by changing the parameters values and verifying in real time the results of the changes. Two experiments are presented.

"Barcode housing system: Integrating floor plan layout generation processes within an open and collaborative system to design and build customized housing." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 656-670. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. The goal of the project has been to design and implement an ICT environment which facilitates the interaction of the different actors (architects, builders, manufacturers, occupants) involved in the design, construction and use of affordable housing built with industrialized methods. The interwoven working environments which form the structure of the system enable the actors to carry out their activities in a synchronous and asynchronous manner. As well as providing a structure that supports collaboration, the system automatically generates housing units and buildings.
Sanguinetti, Paola. "BIM in academia: Shifting our attention from product to process." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 395-409. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper proposes changes in architectural education to respond to BIM technology and the resulting complexity in the design concept. We examine the interoperability issues between design and analysis in professional practice. We present the results of a case study mapping the activities of two interdisciplinary student teams in the early design phases of a BIM-enabled project. Results show the problems associated with building simulation tools, core knowledge lacking in architectural education, and the relationship between information management, team process, and the types of tools used. A flexible curricular structure is proposed in architectural education, expanding our professional roles.
Okuda, Shinya. "Bio-shell (Biodegradable vacuum-formed modularized shelter) ." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. 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.
Dillenburger, Benjamin, Markus Braach, and Ludger Hovestadt. "Building design as individual compromise between qualities and costs: a general approach for automated building generation under permanent cost and quality control." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 458-471. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. We introduce an evolutionary design approach for the automatic arrangement of a predefined space program on a given site. The design goal is to distribute floor spaces while ensuring the essential building performance and usage. The presented evolutionary strategy is applied to acquire optimal design solutions considering both environmental conditions and inner organization under diversified fitness functions. The evaluation process consists of the direct analysis of the spatial network and the physical factors in an adequate accuracy. The method provides a fast generation of qualified volumetric studies. The resulting buildings become a manifested compromise between qualities and cost.
Yue, Kui, Ramesh Krishnamurti, and François Grobler. "Computation-friendly shape grammars: Detailed by a sub-framework over parametric 2D rectangular shapes." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 757-770. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. NP-hardness of parametric subshape recognition for an arbitrary number of open terms is proven. Guided by this understanding of the complexity of subshape recognition, a framework for computation-friendly parametric shape grammar interpreters is proposed, which is further detailed by a sub-framework over parametric two-dimensional rectangular shapes. As both the proof of NP-hardness and rectangular sub-framework invoke elements in graph theory, the relationship between shape and graph grammars is also explored.
Mueller, Volker. "Concept design tool requirements: Developing a Framework for Concept Design Tool Specifications." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Early design phases generate high project value with relatively little effort. However, digital tools supporting integrated concept design at a high knowledge level are scarce. Research has focused on specific aspects of design tools yielding focused and disjoint insights. An actionable requirements framework will allow assembly of research results into a meaningful, comprehensive concept design tool set and will reveal gaps which will help identify further research opportunities.
Chen, Tzu-Hao. "Construction Improvements for the Making of Free-Form Glass Surfaces." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. The development of computer technology and new media in architecture has given new rise to the creativity of designers and lead architecture to new break through in construction. The making of CAD/CAM free-form structures, can be divided into the making of curved surfaces and the skeleton.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 487-500. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. There is an increasing awareness of formal ontologies in knowledge-intense problem domains in the AEC industry. This paper analyzes the general use of ontologies, points to the importance of context-dependent ontology descriptions in AEC, and describes the use and management of multiple (external) ontologies as knowledge management tools within a complex information model of a building performance assessment tool CLIP (Computational support for Lifecycle Integral Performance assessment), previously developed by the authors. The paper provides a discussion of our approach, analysis of the benefits and limitations of external ontologies, suggestions for further development and research areas for the integration of multiple AEC knowledge representations.
Oxman, Rivka. "DDNET: the conceptual structure of digital design Emerging body of concepts of digital architecture." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 601-613. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. The ability to define novel body of concepts related to digital design media is becoming a central issue in the attempt to establish the theoretical foundations of Digital Architecture. The aim of this research is to identify and map the design concepts and relevant methodologies of digital design in architecture. In making the survey, analysis and the categorization of relevant concepts and emerging precedents we formulize a theoretical basis for the conceptual mapping of this field which is termed DDNET: Digital Design Network. The DDNET is a semantic system divided into 4 levels: key-concepts, sub-concepts, system level and precedent level.
Oh, Yeonjoo, Ellen Yi- Luen Do, Mark Gross, and Suguru Ishizaki. "Delivery Types and Communication Modalities in the Flat-Pack Furniture Design Critic." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. A computer-based design critiquing system analyzes a proposed solution and offers critiques (Robbins 1998). Critiques help designers identify problems as well as opportunities to improve their designs. Compared with human critics, todayis computer-based critiquing systems deliver feedback in quite restricted manner. Most systems provide only negative evaluations in text, whereas studio teachers critique by interpreting the studentis design, introducing new ideas, demonstrating and giving examples, and offering evaluations (Bailey 2004, Uluoglu 2000) using speech, writing, and drawing to communicate (Anthony 1991, Schön 1983). This article presents a computer-based critiquing system, Flat-pack Furniture Design Critic (FFDC). This system supports multiple delivery types and modalities, adapting the typical system architecture of constraint-based intelligent tutors (Mitrovic et al. 2007).

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 65-79. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper presents the results of a comparative study between traditional analogue tools (sketches and physical models), a CAD software (digital) and a hybrid tool (digital and analogue) that allows immersive freehand sketching and model making (the Hybrid Ideation Space), in order to assess their respective abilities to support collaborative ideation. By comparing these tools, we were able to better understand the relationship between the activity of collaborative ideation, the tools that support it and the experience of the designer in order to provide principles for the development of collaborative tools in design.

"Design with space syntax analysis based on building information model: Towards an interactive application of building information model in early design process." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 501-514. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper introduces a new framework to enable user-friendly space syntax analysis during the initial design stage. It assists designers, without in-depth knowledge on space syntax, to evaluate and compare design outcomes rapidly. The framework is realized by integration between space syntax and building information model in which space topology is autonomously retrieved. A BIM modeler so called “ArchiSpace” has been developed to demonstrate the applicability of the framework to design practice. Our experiment shows that designers can use the modeler to analyze their design alternatives instantly at any moment during the initial design stage. Therefore, users can generate and evaluate their design alternatives simultaneously without distraction and tedious work on the space syntax analysis in detail.
Rosenberg, Daniel. "Designing for the unpredictable: Novel model for the design of emergence through real-world behavior." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 847-860. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Most current approaches to unpredictability, within architectural discourse, lie either in the design of unbuildable emergent shapes or in performance simulations to test already designed outcomes. Even though some recent explorations have enabled the construction of emergent shapes, the unpredictability of real-world behaviours as the rulesi source for the unpredictability of shape generation remains unexplored. This paper proposes a novel model for the design of unpredictable buildable shapes, based on real-world behaviours. Initially, current methodologies are studied in order to find how they deal with the unpredictability of shape generation and real-world behaviours. Finally, a comprehensive novel model is proposed and tested through an empirical experiment, to show how it can be applied in architecture.

CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Do designers mentally capture the image in the design process? If so, to what degree can these mental images be transformed and interpreted into useful design information? This article discusses the “characteristics of designers” mental activities and proposes the use of mental images to generate design diagrams.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 800-814. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. We present an example of parametric modelling of a large span roof and discuss a parametric approach to integrating performance oriented design in the conceptual phase of the design process. In the case study shown here, architectural geometry is related to structural morphology, as part of a larger process, its parameterization aims at supporting further performance related investigations, including thermal aspects, by meaning of both the large scale investigation and a more detailed level of design.
Guité, Manon, Ivanka Iordanova, Giovanni De Paoli, Temy Tidafi, and Jacques Lachapelle. "Digital environment for learning and designing architecture." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 369-382. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This research aims at stimulating the exploration process in architectural design through the conception and the creation of a computational environment centered on a library of referents. Based on a specific way of describing the referents, as well as on the energizing role we wanted the library to play in the design process, we could draw the characteristics of such an environment. The representation of the referents is seen as a combination of descriptions in different format. Offered to students, it allows for new interpretations, for interaction with their content, and finally, for the integration of knowledge during the process of architectural exploration.
Tamke, Martin, and Mette Ramsgard Thomsen. "Digital wood craft." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 673-686. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. In 1995, Robin Evans points out in his book The Projective Cast how the development of techniques changed architecture and the space inhabited in times of Gothic and early Renaissance. We see a parallel phenomenon today, where the interplay of technology and tool gives shape to new design (Kolarevic 2005). Yet in opposition to the interwoven fields of design and craft of the late Gothic, todayis building sector is enormously diversified, and a growing complexity in the building process and number of used materials can be observed. This gives an opposite point of departure into a more integrated field of design and innovation in architectural design and building industry.
Ciblac, Thierry. "Dimensional analysis as support toward optimization in architectural conception phase: applications to structural cases." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 472-486. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. One of the research ways carried out in the ARIAM-LAREA laboratory aims at giving to architects computing tools for early evaluation of structures. A particular approach uses dimensional analysis and similitude properties in order to define parameter variation laws. Such laws are illustrated by analytical cases using the theory of strength of materials. For complex structures, a heuristic is proposed to give indications of parameter variation influence on mechanical behaviour. Some applications are presented for early determination of structural size and limit values, using computations by finite element method.
Meagher, Mark, David Van der Maas, Christian Abegg, and Jeffrey Huang. "Dynamic ornament: Climatically responsive surfaces in architectural design." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 353-366. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. In recent years, sensors and sensor networks have been broadly employed in buildings to monitor diverse aspects of the built environment. Sensors are commonly used to track indoor and outdoor climatic variables such as humidity, temperature, and solar radiation, and to recognize patterns in the activity of people. We propose that in addition to this common instrumental role, data gathered from sensors could also play an important aesthetic and cultural role in the design of engaging architectural spaces. We describe a design study that explores the use of sensor data as a means to qualitatively differen-tiate between spaces within the building, a role traditionally performed by architectural ornament.
De Vries, B., Joran Jessurun, and Gaby Sadowski-Rasters. "Dynamic plan modelling and visualization: Converting an urban development plan into a transition scenario." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 727-739. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Application of 3D models in urban planning practice is still limited to visualization of existing or newly designed situations. Municipalities are looking for possibilities to communicate the transition process of the urban development area with the citizens. A prototype system was developed to investigate what the technical requirements are of such a tool and what the organizational consequences will be. As an example, screenshots are shown of a district in Eindhoven at different moments in time. Finally, recommendations are given on what is needed to turn the prototype into a professional tool.
Ireland, Tim. "Emergent space diagrams: the application of swarm intelligence to the problem of automatic plan generation." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 245-258. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This work investigates how diagrams of architectural space might self-organize relative to specific associational parameters to generate diagrams of spatial organization. The premise is that buildings are systems of spatial relations defined by the dynamic interactions of various autonomous spatially discrete entities. Looking to swarm intelligence, the focus here is on the problem of circulation and explicit spatial arrangement. The paper reports an investigation of emergent route formation and spatial connectivity based on simple agent and pheromone interaction. An array of ant colonies defines the system. A colonyis nest represents a specific space. Space-agents transmit information throughout the space-colony population, defining an emergent communication network.
Din, Edouard, and Athanassios Economou. "Emergent symmetries: visual computations - a group theoretical analysis of the Smith House by Richard Meier." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 173-187. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This work proposes the use of partial order lattices along with represent-ational schemes to account for patterns of ambiguity and emergence in the description of designs. The complexity of such designs is viewed as an aggregation of spatial layers that can all be decomposed by the subgroup relations of the symmetry of the configuration. At the end, this methodology points to a combinatorial approach that generates visual prototypes for future use in design synthesis. Here, Meier's work is just a case study that validates the group theoretical approach.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 314-327. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. 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.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 51-64. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009.

3D virtual worlds for collaborative design learning have been widely recognized and practised, nevertheless there is a general lack of formal evaluation with empirical evidence for the performance of virtual worlds, and their roles in developing studentsi teamwork skills. In bridging these gaps, this paper provides a critical discussion of the effectiveness of virtual worlds for collaborative design learning, supported by a comprehensive analysis on the results of an inclusive questionnaire completed by architectural students. The paper provides insight into the application of virtual worlds in both technical and procedural experiences, and discusses the benefits and shortcomings of virtual worlds on design education.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 159-172. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This work focuses on the development of a tool capable of assisting and supporting architectural design activity. We propose an evolutionary mechanism through the use of a genetic algorithm. Environmental parameters are convoked to drive the evolution. The solar passive qualities of the object under study allow the energizing evaluation. This paper deals with the interaction between verbal thinking and visual thinking through the use of this generative tool.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 105-118. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper deals with 3D modelling of complex architectural elements for virtual 3D scene reconstruction based on images or point clouds. It presents a new method at the opposite of classical photogrammetry and lasergrammetry techniques: parametric components are created and then adapted to the measured data. We have conceived and developed a parametric shape generator tool for virtual 3D reconstruction of cultural heritage monuments. We present the geometrical study on the cupola shapes with all their diversity. It is illustrated with the Suleymaniyé Mosque in Turkey. The results are promising. The modelling time is greatly reduced.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 443-457. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This study is interested in the attribution of technological properties to geometrical elements in a 3D architectural modeler. We propose an original method based on the principle of semantic groupings of faces by geometrical requests. We describe the method and the results of interviews led with architects to identify the relevant groupings, then we list the simple geometrical requests developed within the modeler for the selection of these groupings and we report the efficiency of the method on a case. We conclude by the benefits and limits of our method.
Beirão, José, José Duarte, and Stouffs Rudi. "Grammars of designs and grammars for designing - grammar-based patterns for urban design." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Analytical work has demonstrated the potential of shape grammars for capturing rules embedded in existing design styles, and generating designs within such styles that match given design contexts. However, the creation of grammars for new design styles, from exploratory rules to design synthesis, remains elusive. The combined use of patterns and discursive grammars is here proposed as a way of encoding the semantics behind recurrent urban design operations and enable the development of a tool to support the creation of new grammars. The idea is that by exploring the combination of generative patterns designers may arrive at new grammars.
Hung, Pei-Chien. "How do media influence one s thinking? the “habit media” in design thinking." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 614-625. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper presents a preliminary observation of the digital media as “habit media” in designing act. The digital media has become a costumed vehicle for designers for a long time. The author investigated the supports of different media for how a specific media conditioned the design thinking and the reasons behind the behaviours of choice-use of designers choice. The results showed that designers using “habit mediai could do most part of things they wanted to do, when the media are “habit mediai,  its inherent restrictions do not limit useris accomplishment. Once a digital medium is habitually practiced, it can support the functions and characteristics that this medium does not ever possess.
Chen, Qunli, and B. De Vries. "Human visual perceptions in built environment: Applying image-based approach for architectural cue recognition." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 328-341. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper first presents a review on visual perception in the built environment and human vision simulation. Followed by the description of the Standard Feature Model of visual cortex (SFM), an architectural cue recognition model is proposed using SFM-based features. Based on the findings of the experiments it can be concluded that the visual differences between architectural cues are too subtle to realistically simulate human vision for the SFM model.
Hsu, Yin-Cheng. "Lego Free-Form? Towards a Modularized Free-Form Construction." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Design Media is the tool designers use for concept realization (Schon and Wiggins, 1992, Liu, 1996). Design thinking of designers is deeply effected by the media they tend to use (Zevi, 1981, Liu, 1996, Lim, 2003). Historically, architecture is influenced by the design media that were available within that era (Liu, 1996, Porter and Neale, 2000, Smith, 2004). From the 2D plans first used in ancient egypt, to the 3D physical models that came about during the Renaissance period, architecture reflects the media used for design. When breakthroughs in CAD/CAM technologies were brought to the world in the twentieth century, new possibilities opened up for architects.
Charbonneau, Nathalie, and Pierre Grussenmeyer. "Making use of 3D programming to document and enhance an architectural vocabulary: Case study dealing with artefacts of the Canadian built heritage." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 133-142. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper examines the objectives and describes the methodology of an ongoing research project concerned with the built heritage of Montreal, Canada, more precisely, with the openings (doors, windows, bow-windows, dormers, etc.) in residential buildings. Within the framework of this project, we aim to implement digital environments to document and enhance the architectural vocabulary of openings. We adopt 3D programming to describe the way in which the artefacts are assembled from different components. The aim of this process is to enable the introduction of variations into the principles governing the composition of the artefacts, so as to generate new configurations.
Aksamija, Ajla, and Ivanka Iordanova. "Multimodal representations of architectural design knowledge: Interaction between visual and ontological models." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 642-655. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper presents multimodal representation of architectural design knowledge, where explicit and implicit information are linked. The aim is to develop computational environment that combines several modes of representation. Integration of interactive digital-models library and ontological model of architectural design factors is investigated.
Shih, Shen-Guan, Yen-Hung Chen, Shan-Ching Hu, and Ching-Yuan Lin. "On the simulation of pedestrian behavior: a stochastic model based on Markov chain and information space." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 861-874. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Pedestrians move according to their internal states and the spatial information that they perceive at their locations. We use Markov chain to define the state transition of a pedestrian as a stochastic process, and the concept of cellular automata to simulate the way information disseminates in space. We have implemented an agent-based computer program to observe some emergent behaviours from the interactions between pedestrians and the information space they are surrounded. It is expected that the representational model can be used to assist designers in analyzing the relation between building plan and the circulation pattern.
Chung, Daniel, Steven Zhiying, Jayashree Karlekar, Miriam Schneider, and Weiquan Lu. "Outdoor mobile augmented reality for past and future on-site architectural visualizations." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 557-571. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Mobile devices have become widely used in outdoors on-the-move applications. Our research aims at developing a system which allows users to visualize the virtual buildings, streets, historic sites, landscapes or cityscapes (in the past or future) which are rendered seamlessly with the current actual scene captured by the camera (called Augmented Reality), and interactively exploring the virtual scene in real-time while the user is moving. We use the camera PDA, the GPS receiver and the gyroscope to track the mobile deviceis position and orientation for virtual scene rendering. This article documents the issues regarding accurate alignment, tracking, errors and limitations with mobile devices and presents our solutions generated so far for the research in progress.

"Parametric methods of exploration and creativity during architectural design: a Case study in the design studio." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 423-439. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Parametric methods from different modelling paradigms were proposed to students in a design studio. The influence of these methods on creativity was studied using qualitative methodology. “Generation” was found to stimulate “abundance” of ideas and to lead to different evolution and flexibility, as well as to higher “engagement” in the design process.
Tahrani, Souha, and Guillaume Moreau. "Perception of urban space through virtual reality." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 533-546. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009.

Urban environment is a “sensiblei space, it can manifest itself to our senses through the process of perception. The comprehension of the relation between man and his environment requires a study of spatial perception and its modes of interpretation. This paper proposes to study the perception by using the Virtual Reality (VR) technologies as a tool of qualitative analysis. The study presents an exploratory analysis of visual perception in a real urban path and its virtual modelling. It shows the potentials of virtual environments in the qualitative assessment of urban spaces.

Attar, Ramtin, Robert Aish, Jos Stam, Duncan Brinsmead, Alex Tessier, Michael Glueck, and Azam Khan. "Physics-based generative design." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 231-244. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. We present a physics-based generative design approach to interactive form-finding. While form as a product of dynamic simulation has been explored previously, individual projects have been developed as singleton solutions. By identifying categories of computational characteristics, we present a novel unified model that generalizes existing simulations through a constraint-based approach. The potential of interactive form finding simulation is explored through exemplary studies: a conceptual approach to a fixed form that acts as a visualization of interacting forces, and a constraint-based model of the fabrication logic for a panelization system are examined. Implications of constraint-based simulation on future directions are discussed.
Tan, Beng-Kiang, and Stephen Yee. "Place-Making in Online Virtual Envionment: the Case of Second Life." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. With Internet bandwidth becoming better and more affordable, coupled with rapid advancement in web technology, multiuser online 3D virtual environments have become a reality and increasingly popular. One such world, Second Life (launched in 2003), has 2.3 million “residentsi living in their virtual platform as of January 2007. The residents “live”, work and play there. They also socialize in public spaces inside this virtual environment. 
LaBelle, Guillaume, Julien Nembrini, and Jeffrey Huang. "Programming framework for architectural design ANAR+: Object oriented geometry." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 771-785. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The presented research explores the use of programming as explorative and reflexive medium (Schin, 1983) through the development of a programming framework for architectural design. Based on Java, the ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depend on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations.
Sommer, Bernhard, and Norbert Palz. "Prototyping dynamic architecture: Material properties as design parameters." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 687-699. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper documents an ongoing research that combines recent developments in the field of Rapid Prototyping Technology for a materialisation of composite pneumatic models. The ability to create three dimensional prints with varying surface materials has the potential to assign the RP model a different role in the design process. The implementation of material performance, configured through CAD driven geometry, allows for an emergence of dynamical models that are freed from conventional representational function.
Abdelhameed, Wael. "Reciprocal relationship of conceptualization and design problem definition: a proposed approach for an architectural design studio." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 410-422. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009.

This research paper proposes an approach to be applied in the design studio. The proposed approach highlights the reciprocal relationship between concept articulation and design problem definition in a design method that exposes different design activities related to this relationship. The design method was applied in a design studio of an intermediate level. The study reports the analysis of student designs in terms of the deign method employed. Moreover, a survey was carried out in order to measure the responses of students and instructors regarding the design method and its approach. The main structure of the design method proposed can be described as follows: although the relationship of concept articulation and design-problem definition are reciprocal, the influence of one direction can be distinguished more than of the other direction on different design activities. The research using qualitative and quantitative methodologies analyzes the results and outputs of the theoretical investigations, the practical application in the design studio, and the questionnaire responses through different methodological tools.

Lee, Juhyun, Jeong Song, and Kunsoo Oh. "RFID applications in a building project." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 700-712. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. As a new paradigm for construction in the ubiquitous era, IT Technology like RFID is an emerging issue in the building industry. For the purpose of RFID technology application in the building industry, this research suggests the Information Lifecycle Management using RFID technology in apartment building project and deals with the context-aware scenario for RFID technology application. The final objective of the research intends to develop the RFID application for the construction industry. From the tagging nodes at the material manufacture stage to the reading nodes at the end stage of the construction process, the flow of the RFID information deals with the synthetic application connecting physical construction material with electronic RFID information for the management. Furthermore, we suggest how to systematize, distribute and manage the construction material with the Information Lifecycle Management.
Lin, Chieh-Jen. "Smart topological geometry: an interactive tool for coordination of spatial topology and geometry." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 342-352. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper describes a prototype of an interactive tool named Smart Topology Geometry (STG) for coordination between spatial topology and geometry in the early design phase. STG focuses on the manipulations of virtual spaces and can manipulate the topological relations among them by instantly modifying the geometric properties of spaces so as to comply with the topological relation defined by the user.
Ireland, Tim. "Sniffing space II: the use of artificial ant colonies to generate circulation patterns in buildings." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 214-227. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This model uses agents, which lay and respond to alternative pheromone trails to define circulation routes between specific locations. There is no a priori knowledge embedded in the model. The communication network generated between the colonies represents a routing structure, which is emergent and dynamic. The intended application is for building types that are specifically defined by complex circulation parameters, such as airports, hospitals and schools. Proposed here, is a generative process in which the circulation patterns between specific destinations and the spatial arrangement emerges in a process of mutual compatibility.
Nembrini, Julien, Guillaume LaBelle, Nathaniel Zuelzke, Mark Meagher, and Jeffrey Huang. "Source Studio: Teaching Programming for Architectural Design." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. The architectural studio framework presented here is based on the use of programming as central form generation reflexive medium (Schön, 1983). Its aim is to teach architectural design while introducing a different approach toward computer tools by enabling students to fully explore variations in their designs through the use of coding for form definition. It proposes the students to reflect on their design process through its confrontation to algorithmic formalization (Mitchell 1990). This results in exercising the synthetic re-thinking of their initial sketch intents to comply with the difficult task of fitting the language syntax. With the proliferation and constant replacement of computer tools among the architectural practice, a shift appears in the attitude towards introducing students to different tools: studio teaching is branded by specific software platforms advocated by the teaching team. A lack of generalized view, independent of commercial CAD software, is problematic for the definition of new teaching tools suited for this constantly evolving situation (Terzidis, 2006).
Wang, Wie, Xiangyu Wang, ( Irene), and Rui Chen. "Spatial Faithful Display Groupware for Remote Design Collaboration." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Traditional remote collaboration technologies and platforms are found restrained and cumbersome for supporting geographically dispersed design activities. Based on Single Display Groupware (SDG) (Stewart, Bederson, and Druin, 1999) and Mixed Presence Groupware (MPG) (Tang, Boyle, Greenberg, 2004), a Spatial Faithful Groupware is presented in this paper to address some issues in remote collaboration. This paper discusses some of these limitations and argues how these limitations could possibly impair efficient communication among designers.
Crotch, Joanna, Robert Mantho, and Martyn Horner. "SPATIALGENESIS: Event based digital space making." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 188-199. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Digital technologies and processes have been used to generate architectural form for over two decades, now the recent advances in digital technologies have allowed virtual digital environments to be constructed from physical movement. But can a bridge that connects the physical and virtual realms be developed? Can this currently arbitrary form making be grounded in human activity and subsequently be integrated in to real time, space and place.
Chen, Irene, and Xiangyu Wang. "Tangible augmented reality: a new design instructional technology." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 572-584. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper discusses the proposed idea of using Tangible Augmented Reality to gain design knowledge since information sharing has been limited by one way receiving knowledge without enough response and interaction in the learning process. The new instructional technology is not only available through visual cues, but also opens up multi channels from different cues. It describes some guidelines for space utilizing between buildings and followed by a scenario. The proposed system offers three levels of information which affects aspects of individuals experience of space as they move the digital contents in the real environment.
Eshaq, Ahmad Rafi Moham, Avijit Paul, Siti Noraishah, and Mohd Nazri. "Techniques on heritage preservation using lighting computation virtual environment." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 95-104. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This research presents the results of experiments of techniques on heritage preservation using lighting computation in virtual environment. In this research, three traditional houses built in the early 1900s were re-constructed based on the captured data that included texturing and lighting. A thorough study on the lighting solution and its impact to the design aspects of photorealism and issues discovered in processing the digital data will be emphasized. This includes complexity of the modelling, rendering and reality, and real-time lighting techniques. This research will suggest effective lighting techniques for re-construction of heritage preservation in virtual environment for architectural purposes.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 303-313. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Improved adherence to hand hygiene (hand washing or use of alcohol-based hand rubs) can significantly reduce the transmission of multi-drug resistant organisms and prevent many healthcare associated infections. This paper describes a technological intervention with sensing and reminding mechanisms for hand hygiene adherence in a smart patient room.
Kalay, Yehuda. "The impact of information technology on architectural design in the 21st century." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 21-34. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Architecture uses technology to achieve certain functional, cultural, social, economic, and other goals. In turn, technology transforms the discipline. Information technologies promise to change design processes, practices, and products. The first uses of computing in the service of architecture have been rather timid, mimicking older practices. This is changing rapidly: new design and evaluation tools allow architects to imagine new building forms, more responsive (and environmentally more responsible) buildings, even radically new types of environments that blend physical with virtual space. Understanding and shaping this transformation are the basis of architectural design research and education in the 21st century.
Ashraf, Mohamed-Ahmed, and Pierre Cóté. "The Impact of Three Cognitive Functions on Digital Media Aided Architectural Ideation: a Proposed Investigation." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. From a cognitivist perspective the architectural design seen as an iterative process of search for an “acceptable” solution from initial design assumptions (Simon 1974) requires representation. These representation which may be internal (mental/cognitive activities) and external (sketches 3D models) are essential to any creative act and in all phases of the design process since they constitute a projection of the architectis thought and know-how.
Wang, Chung-yang. "The Modular Units of CAD/CAM Fabrication." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. After Frank OiGehryis completion of the fish sculpture in Barcelona, the technique of CAD/CAM fabrication has gradually matured. Designers could use computer to acquire the freedom of form without most restrictions. Typical CAD/CAM fabrication can precisely capture the sections of 3D (three-dimensional) freeform and output those contours into 2D (two-dimensional) structures by computer assistance (Kolarevic 2001, Groover and Emory 1984). In the procedure, due to the accurate output of frameworks, designers could realize the outlines of complicated forms in a low error way. After making frames, architects have to attach suitable skins on the structures according to different situations of form (Lim 2006). It is a traditional CAD/CAM fabrication which has established for a long time.
Bourbonnais, Sébastien. "The possible invention of digital architectures. Use of images: from a model to the construction." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 288-300. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Computer-Aided Design (CAD) has become more and more part of the common architectural practice. Some designers have explored (in the past) different aspects, especially formal ones, allowed by these new information technologies. This paperis goal is to explore the invention that would be specific to this new architectural practice. The hypothesis is to go back to the specificity of the image and to examine its evolution. This analysis will be done with reference to the « cycle of images » of the French philosopher Gilbert Simondon, described by means of stages and levels. This particular way of thinking will allow us, besides an overview of all those images in a genetic diagram, to reveal what can enable the passage from one level to another. We call this: “invention”.
Kwee, Verdy. "The Secret Garden via CAD education: Online digital architectural information presentation." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 383-394. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Could information presentation on the digital platform aide knowledge formation to the extent that it changes the discourse of the overall architectural discipline? This paper discusses issues and possibilities related to architectural information presentations - how tradition has shaped our position and thinking today, and how architecture students could possibly redefine digital information presentation and its conventions tomorrow. The paper highlights an experimental approach to a CAD course reintroducing digital presentation where visual explanations in architectural presenta-tions were emphasized while the strengths and indispensability of other abstractions acknowledged. The paper also discusses the process, challenges, caveats and outcomes of the course.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 626-641. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009.

This paper is concerned with the ongoing changes and the evolution of CAAD using machine-assisted techniques. It is feasible to create a hypothesis of the identity of the discipline depicted in the archived published output, and semantically link it to the data cloud. This allows for expansion of the meanings embodied in the research and inference about what CAAD is, and to trace back how the field progressed. We present several case-studies showing how this inference is done and finally, observations are elaborated and an outlook on further work is discussed.


Cet article traite des changements actuels et de l’évolution du CAAD basé sur des techniques ayant recours à des machines. Il est possible de poser une hypothèse quant à l’identité de la discipline représentée par la production publiée archivée et de la lier sémantiquement à un nuage de données. Cela permet de développer la signification au cœur de la recherche, d’inférer ce que le CAAD est, et de retracer comment ce domaine a progressé. Nous présentons quelques études de cas démontrant comment nous procédons à cette induction. Finalement, nous faisons part de nos observations et traçons des pistes de recherche.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 83-94. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. The research results presented in this article propose, with the aid of Information and Communication Technologies and 3D digital modelling, the creation of a communications platform to promote the acquisition of knowledge and to support the management of “sustainable developmenti. These initiatives are essential if sustainable development practices want to make significant progress. The digital environment proposed, which is by nature multidisciplinary, allows for an efficient collaboration between different disciplines concerned with heritage challenges. The purpose of this study is to understand, communicate, manage and envisage heritage within the optic of sustainable development.
Kendir, Elif, and Tim Schork. "Tools for conviviality: Transcribing design." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 740-753. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper presents the outcomes and findings of a semester long trans-disciplinary design studio recently taught at RMIT University, involving students from the disciplines of architecture, industrial design and landscape design. The focus of the studio was to investigate the creation and appropriation of tools for innovative design processes. Drawing on craft theory and theories of design and computation, this paper illustrates how tools can transgress disciplinary boundaries and investigates how an understanding of the intricate relationship between tools, techniques, the media they operate in and the design outcome is the premise of a more informed design approach.
Do, Ellen Yi- Luen. "Towards a Smart Living Environment: Happy Healthy Living with Ambient Intelligence and Technology." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Achieving wellness is a Grand Challenge. We are concerned about the quality of life for ourselves and for our society. As human beings we want to develop and cultivate our untapped potential for a happy, healthy, creative and fulfilling life. Technological innovation may be just the key to unlock human potential for the Holy Grail of wellness. Wellness has multiple dimensions: physical, emotional, occupational, social, intellectual and spiritual (Hettler 1976). Below we briefly describe interesting design computing projects employing technological innovations to contribute toward a smart living environment for wellness.

In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This investigation arises from the need to include the systems of environmental natural conditioning and the architectural project in the ecology of the desert dry-climate. In this research, it is proposed to investigate the main features and techniques used in Southern Peru as an answer to build in a desert environment with high levels of sunlight and very few rain days. Identifying the historic processes of the vernacular architecture, in which we recognize evolved coherent forms, making possible to define the strategies with which to recreate architecture responsive to the ecology of the desert dry- climate.
Swarts, Matthew, and Hugo Sheward. "Using multi-level virtual environments as a medium for conducting design review through a shared IFC dataset." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 585-597. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. For a long time the Architecture-Engineering-Construction (AEC) community has had difficulty in communicating the content of their work, not only the various specialties involved, but also to their clients. Studies (Doorst and Cross 2001, Bakhtin 1994) suggest the importance of multi-role collaborative environments in supporting design processes. We are developing a Multi Level Design Review Tool for the AEC industry which allows multiple actors to congregate and interact as agents around a central Building Model. It merges real-time virtual 3D visualization technologies with Industry Foundation Classes (IFC) to support both high levels of semantic content and seamless interoperability.
Tan, Beng-Kiang, and Hafizur Rahaman. "Virtual heritage: Reality and criticism." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 143-156. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Virtual environments which are culturally embedded are often categorized as “virtual heritagei. Emerging media and digital tools offer us the possibility to experience 3D virtually reconstructed historic sites as visitors, travelers or even as resident. Many critics have identified different issues that often inhibit widespread distribution and use of virtual heritage. However, these present criticisms are mostly focused on either the “process” or the “producti but do not consider “user”, i.e. the people using it. This paper attempts to identify and categorize various constraints through investigating present discourse of literature and presents “useri as another inevitable factor to be considered for developing any virtual heritage environment.
Boeykens, Stefan, and Herman Neuckermans. "Visual Programming in Architecture: Should Architects Be Trained as Programmers?" In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. Most commercial CAAD applications have online communities of end users, through blogs, discussion forums and learning portals. On many occasions, questions lead to the conclusion that the software can only provide the desired functionality using scripting or programming, to fill in the gaps of the software feature set. However, more than once, people suggest that architects are not programmers and that they should not be responsible for adding this functionality. Similarly, when guiding students through some of their technical design studio problems, a comparable reaction is noticed. This is especially remarkable, considering the fact that these students had prior programming courses, as part of their Bachelor of Architecture curriculum.
Erhan, Halil, Robert F. Woodbury, and Nahal Salmasi. "Visual sensitivity analysis of parametric design models: Improving agility in design." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 815-829. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. The advances of generative and parametric CAD tools have enabled designers to create designs representations that are responsive, adoptable and flexible. However, the complexity of the models and limitation of human-visual systems posed challenges in effectively utilizing them for sensitivity analysis. In this prototyping study, we propose a method that aims at reduction of these challenges. The method proposes to improve visually analysing sensitivity of a design model to changes. It adapts Model-View-Controller approach in software design to decouple control and visualization features from the design model while providing interfaces between them through parametric associations. The case studies is presented to demonstrate applicability and limitation of the method.

"World8: International working group for new virtual reality applications in architecture." In Joining Languages, Cultures and Visions: Proceedings of the 13th International CAAD Futures Conference, 547-556. CAAD Futures. Montréal, Canada: Les Presses de lUniversité de Montréal, 2009. This paper introduces the activities of World8, an international working group on virtual reality, and demonstrates the groupis developed VR applications in architecture. Group members come from eight universities around the world, including the United States, the United Kingdom, Japan, Chile, Canada, Egypt, and the United Arab Emirates. The main objective is to develop a research framework for collaboration between architectural schools and a software developing company. Specifically, the group is looking to create new applications for VR visualizations of urban settings with dynamic agents such as human and vehicular traffic. Models developed by these members are explained, and the project is reviewed based on survey results.
