title The Use of the Smart Geometry through Various Design Processes: Using the programming platform (parametric features) and generative components
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. 297-304
summary The emergence of parametric generative design tools and prototyping manufacturing technology led to radical changes in architectural morphologies. This change increased the opportunity to develop innovative smart geometries. Integrating these algorithms in the parametric softwares led to variations in building design concepts increasing alternatives and decreasing the repetitive work previously needed in conventional CAD software. The chosen software in this research is Generative Components (GC). It is a software design tool for an associative and parametric design platform. It is tested for using Global Variables with associative functions during the concept creation and form GC comprises features. The results presented in this research may be considered an introduction to the smart geometry revolution. It deals with the generative design which applied in the design process from conceptual design phase, defining the problem, exploring design solutions, then how to develop the design phases. Office building is a building type which encourages new forms that needs computational processes to deal with repetitive functions and modular spaces and enclosed in a flexible creative structural skin. Generative design helps the office buildings to be arranged, analysed, and optimized using parameters in early stages in design process. By the end of the research, the use of the smart geometry in a high rise office building is defined and explained. The research is divided into three parts, first a summary of the basic theories of office buildings design and the sustainable requirements that affect it, and should be integrated. Secondly, the previous experiences in generating office buildings by Norman foster and Sergio Araya. At last, a case study is proposed to test and evaluate the use of the parametric generative methodology in designing an office building with specific emphasis on the function, environmental aspects and form generation using Generative Components (GC) Software.

summary Recent advances in architectural and engineering technology have opened the door for complex architectural expression in today’s built environment. When pushing the envelope on geometric complexity, architects and engineers must begin a dialogue early on in the design process and communicate effectively throughout. Using digital models for communication, visualization, and analysis creates additional digital information that may need to be shared. Middleware provides interoperability between different software packages and facilitates the exchange of information. However, this does not exempt the partners from maintaining traditional lines of open communication. This paper will discuss the importance of open communication and demonstrate a strategy for sharing digital information. The case studies that will be presented are taken from design projects whose geometric complexity required close partnership between design team members. Effective communication will first be discussed in the context of three sculptural concept designs. Second, the interoperability of digital models will be discussed through a case study of a complex, faceted super-tall high-rise tower.

summary 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.

summary In recent years a number of projects have been emerged, in which the new possibilities of the computer as a design tool, have been used. Through the digital chain from design to manufacturing the efficiency has increased and allows the implementation of complex architectural structures. With all these new opportunities, also new challenges arise in the teaching and the educational concepts. The paper describes the detailed course concept and the didactic strategy using the example of a parametric designed roof structure, we designed, planed and build up in scale 1:1 within the main course. „Wendepunkt|e im Bauen“ (Turning point|s of building) is the name of an exhibition at the “Pinakothek der Moderne” in Spring 2010. In addition to contributions of the industrialization in the building industry from 1850 to the present day, the exhibition also serves as a platform, to demonstrate new possibilities of computer-aided parametric design and the closely related computer aided manufacturing (CAM). In this context, we took the chance to build a sculpture in Scale 1:1 to show the potential of a constant digital workflow and the digital fabrication. Through the digital chain from design to manufacturing, the efficiency has been increased by the computer and allows the implementation of new complex architectural structures. But the efficiency of the high-degree-automation through the use of computerized machines usually ends in the production of the components. Because this coincidence of the elements in the assembly often proves cost and time, the aim of the project was to optimize both, the production of components and their assembly as well. As part of the wintercourse 2009/2010 different aspects of automation have been reviewed and new solutions have been analyzed. Together with 15 students of the Faculty of Architecture the complete digital chain started with the first design ideas, about parametric programming through production and assembly had been researched, implemented and brought to reality. In the first steps, the students had to learn about the potential, but also about the problems coming with the digital-design and the attached digital-production. There for the course took part at our computerlab. In weekly workshops, all ideas have been implemented and tested directly in the 3-dimensional parametric model. And thanks to the interdisciplinary work with the Department of Structural Design also static factors had been considered, to optimize the form. Parallel to the digital form-finding process, the first prototypes have been produced by the students. By using the chairs 3D-CNC-Mills we were able to check the programmed connection detail in reality and apply the so learned lessons to the further development. After nearly 3 month of research, designing, planning and programming, we were able to produce the over 1000 different parts in only 4 days. By developing a special pre-stressed structure and connection detail it was also possible, to assemble the whole structure (13.5m x 4.5m x 4m) in only one day. The close connection between digital design (CAD) and digital manufacturing (CAM) is an important point of our doctrine. By the fact, that the students operate the machines themselves, but also implement projects on a scale of 1:1, they learn to independently evaluate these new tools and to use them in a meaningful way.

title Social Experiments in Design Technology
source Computation: The New Realm of Architectural Design [27th eCAADe Conference] Istanbul (Turkey) 16-19 September 2009
doi https://doi.org/10.52842/conf.ecaade.2009.x.f4d
summary The delivery of a successful project demands high levels of collaboration across an expanded design team, which now includes consultants, fabricators and contractors as well as architects and engineers. The pace of development in design technology has been very rapid during the last few years and there are now many software products which offer high levels of sophistication. Most provide associative and parametric modelling strategies, which can be further enhanced and extended by the use of scripting languages. Designers are becoming tool-builders while fabricators are becoming digital craftsmen. With the advent of fast efficient drawing extraction the industry is at last making determined steps towards a model-driven process. However there is no integrated platform which supports the free exchange of ideas, combined with the evaluation of performance, experimentation with production techniques and the evolution of project-specific workflows. In education the design schools have been quick to recognise the potential of the new design technology. This has led to a rapid expansion in course curricula that now offer many new specialisations, most of which also need to be under-pinned by a good grounding in descriptive geometry, mathematics and physics. The architect as a generalist, who coordinates the work of specialists, is being challenged by an increasing breadth of technical studies that require more than just a superficial depth of understanding. In practice the gulf is widening even more rapidly. New graduates, who often have spectacular expertise in modelling and fluency in scripting languages, do not yet have the design and construction experience necessary to direct their efforts to best effect. On the other hand people running project teams do not have the technical background to understand the potential of the skills and resources that are available. Today there is no longer the continuity that used to derive from apprenticeship. As we experiment we find that tools based on new ideas and techniques can radically change workflow – but fear of the unknown can provoke resistance. So the problems we face in harnessing the new technology are as much social and cultural as they are technical. The presentation will focus on developing attitudes towards tool-building with the aim of integrating design, analysis and production. This is part of a continual and quite gradual process, which requires the ability to play interpretive roles that help to bring about cultural change. Examples will be shown from the work of the Specialist Modelling Group at Foster+Partners who now have tenyears experience in deploying design technology in an environment where research is intensely project driven.

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 “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ 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’s 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 Building Thailand's tallest Ganesh: CAD/CAM integration in conventional metal fabrication
source Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 337–346
doi https://doi.org/10.52842/conf.caadria.2012.337
summary Ganesh (Ganesa or Ganesha) is a Hindi god well known for his distinguishable elephant head and widely revered as the god of success or remover of obstacles. Patrons in Thailand have worshipped Ganesh and respected him by means of erecting statues of Ganesh in various poses and sizes throughout the country. In late 2008, the people of Chacheongsao, a province located East of Bangkok, decided to create Thailand’s tallest standing Ganesh statue made with bronze reaching heights up to 39 meters and situated on the Bangpakong river bank overseeing the city and its people. The author and design team was approached by representatives from Chacheongsao and commissioned to advise the process from conception to construction. The challenge started with seeking appropriate computer-aided design and manufacturing technologies and innovative processes to guide the design team throughout the production. The 0.60-meter bronze cast sculpture of the Ganesh was scanned using a 3D optical scanner to generate a solid model of the statue. A surface model was then extracted from the 3D model to firstly determine the most efficient structural support within the statue and secondly to generate surface strips for the foundry to create actual bronze casts. The construction of the project began early 2009 and the statue has since been erected from its base to currently its head. During construction, the author and design team has encountered several problems translating pixels to parts. Several errors have occurred during the mould and cast production process as well as construction errors on site causing mismatches of the structure and surface, misalignments, and protruding structural supports and joints. The lessons learned from this project is documented and analysed with hopes to create a more effective process for future projects with similar requirements.

summary The main objective of this research is to determine through the use of a CAD-BIM system, the emission of CO2 in the pre-operational phase of construction. Based on a case study in quantitative analysis of materials and the BIM system, it was possible to quantify the amount of CO2 emitted during the pre-operational life cycle of a building. By using this feature you can provide, before the begining of construction, the total CO2 that will released to the environment, and other analysis.

title Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) 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. 451-476.
summary The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building’s Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 435-450.
summary Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

title Digital Design of High-Rise Buildings with Tessellation and Mapping

summary A new high-rise building, when inserted in an existing urban environment, cannot have all the floor plans identical since the visual and environmental constraints change from floor to floor due to the interference of neighboring buildings, sun light, prevailing wind and noise. So how can we design a building that takes into consideration all this variables? How can digital design tools help? (DELPINO, 2014). We believe that a building like that can be designed constructing facade maps which allow a floor by floor analysis considering visual, wind, noise and sun light constraints. We believe that facade maps analysis and their superposition provide clues of how each floor plan can be built to provide comfort and to take most advantage of the view. (DELPINO, 2014). We believe that variation techniques such as tessellation and morphing can provide the formal bases for such design. We believe that digital design tools are vital both for analysis as well as for designing this type of building. (IWAMOTO, 2009, p. 35-59; MOUSSAVI, 2009, p. 42-216).

title Thermal Simulation In Residential Building Within Computer Aided Architectural Design: Integrated model
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. 235-243
summary Nowadays, the architectural profession is seeking a better energy saving in the design of buildings. The fear of energy shortage in the very near future, together with the rapid rise in energy prices, put pressure on researchers on this field to develop buildings with more efficient heating systems and energy systems. This work is concerned mainly with the development of a software program analyzing comfort in buildings integrated in CAD architectural systems. The problem of presenting the computer with information concerning the building itself has been overcome through integration of thermal analysis with the building capabilities of CAD system. Mainly, such experience concerns the rules for calculating heat loss and heat gain of buildings in Algeria, The program has been developed in order to demonstrate the importance of the innovation of the computer aided-architectural-design field (CAAD) in the technology of buildings such as the three dimensional modeling offering environmental thermal analysis. CAAD is an integrated architectural design system which can be used to carry out many tasks such as working drawings, perspectives and thermal studies, etc., all from the same data. Results are obtained in tabular form or in graphical output on the visual display. The principle of this program is that all input data should be readily available to the designer at the early stages of the design before the user starts to run the integrated model. Particular attention is given to the analysis of thermal aspects including solar radiation gains. Average monthly energy requirement predictions have been estimated depending on the building design aspect. So, this integrated model (CAAD and simulation comfort) is supposed to help architects to decide on the best options for improving the design of buildings. Some of these options may be included at the early design stages analysis. Indications may also be given on how to improve the design. The model stored on CAAD system provides a valuable data base for all sort analytical programs to be integrated into the system. The amount of time and expertise required to use complex analytical methods in architectural practice can be successfully overcome by integration with CAAD system.

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 “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title Un « collaboratoire » comme nouveau contexte pour la transformation des pratiques via la technologie; A "collaboratory" as a new context for transforming practices through technology
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 37-50
summary 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.

summary The paper highlights a built example of a human-scale spatial environment composed of discrete collaborative modules. The primary goals were to develop and understand strategies that can be applied to interactive architecture. The design and construction were carried out in an academic context that was displayed to a public audience of approximately 200,000 people over the course of three days. In addressing the performance parameters of the prototype, the concept focused on several key strategies: 1) geometry 2) movement 3) connections 4) scale and 5) computational control, and human interaction. The final objective of the approach was to create an innovative design that was a minimally functional spatial environment with the capability for evolving additional multi-functionality. Heavy emphasis was placed on creating a full-scale environment that a person could walk through, interact with, and experience spatially.
