summary The combination of new materials and digital design has a transformative potential, providing building products and architecture tailored specifically to the clients’ needs and site requirements. This is the essence of the architecture of mass costumisation or personalised production. How can one demonstrate this physically when in essence the product is significantly ahead of current production capabilities? This was the dilemma faced by architects James Timberlake and Stephen Kieran of KieranTimberlake Associates, when asked to design a pavilion for the Cooper-Hewitt National Design Museum in the autumn of 2003. Their response is the SmartWrap Pavilion. The SmartWrap concept will deliver shelter, climate control, lighting, information display and power with a printed and layered polymer composite. The aluminium-framed pavilion is clad in a printed skin based on a combination of polyester and its derivative polyethylene terephthalate (PET), which was developed with DuPont. The pavilion was designed using a single project model, and all the aluminium extrusions of the frame were barcoded. This coding defined their structural and construction properties.

summary Since 2003, we have been developing a pedagogic proposal and didactic material for teaching Light and Optics to kindergarden children that enhances the construction of the first scientific thinking schemes. The design (industrial and graphic) applied to this project has generated an educational product composed of 44 objects. These materials allow teaching concepts such as: combination of colors, light indispensable to see, formation of shadows and images are not objects. These have been developed as inciters of curiosity, capable to awake the innate restlessness of children, achieving to stimulate their creativity. The purpose is to explore knowledge and construct their own ideas; enrich their experiences and inquire a reality that was drawn grey and tedious, generating a process of manipulation-action and then representation-conceptualization. This product has been successfully used as a pilot test in a kindergarden, reflecting significant gains in students’ science learning. [Full paper in Spanish]

summary A significant quantum of all buildings constructed in modern times is designed for residential purpose. A tremendous amount of money is being spent every year for construction of residential buildings. Therefore, optimization of design becomes very important. In a country like India most people in urban area live in houses having constrained area. A significant part of residential units comes under mass housing either as high-rise building blocks or as plotted developments. In any of such schemes there are large number of housing units for a group of families of whom general characteristics are known but characteristics of individual families are not known at the time of designing. This situation is, however, suitable for scientific investigation and analysis based on statistical surveys. Broadly speaking, this paper suggests approach to deal with this situation of finding optimum layout of rooms of a housing unit for any target group of families when the covered area is so constrained that freedom of using different criteria like aesthetics, structural systems, materials and methods of construction in varieties of ways is drastically reduced. In such constrained area for housing units rooms are generally found rectangular within overall rectangular outline of each unit. Method shown here is valid under this restriction. It is also assumed that number of rooms will be restricted to such number that exhaustive search for design is practically possible within a reasonable time with present day capabilities of normally available PCs.

summary IMLAB (Interdisciplinary Modular Learning System for Architecture and Building Science) is a project, startet by three schools of architecture in Germany: a modular, digital and online-based system, which has the aim to collect and improve teaching elements from architectural schools around the world. The development of digital teaching materials at every single university is very expensive - so the idea is to motivate schools all over the world to contribute their teaching materials and teaching moduls. It could work like an architectural ""napster"". The initial development of this kind of teaching community was funded by the German Federal Ministry of Research as a research project. The momentary state of work is documentated on the following website: www.imlab.de. Unfortunately all the information is in German up to now - we will develop the english version as soon as possible. We do have interactive workshops and design-projects beetween different universities up to now (in Germany) and several contacts to international partners. We would like to use eCAADe 2003 as a platform for multiplying this idea and finding more partners from all over the World.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London.

source Scientific Bulletin, Faculty of Engineering, Ain Shams University, Vol. 38, No. 2, June 2003 - pp. 297-310
summary Expert systems are computer systems developed to preserve the human expertise about specific domains in a well-structured form suitable for retrieval and manipulation by computers. They have been used in many fields of applications and proved to be beneficial. This paper addresses the role of Knowledge-based expert systems in building construction; particularly in the diagnostics and assessment of buildings' cracks. The paper presents BUIL-D-EX; a prototype for a Buildings’ Diagnostics Expert system intended to assist architects, structural engineers, contractors and even building owners in identifying and suggesting remedies to concrete and masonry surfaces' defects. The system identifies the kind of crack, states its most probable causes and its degree of danger, suggests a technical remedy and finally suggests several commercial names for materials to be used for curing the defect, and how to apply them. BUIL-D-EX offers complete explanations for all its questions to the users, as well as justifications for all its decisions and answers whenever needed.

summary For many years, CAD software depended on entity objects that were manipulated and interpreted by the user as meaningful symbols. These entities only represented the geometrical aspect of the design, but never had knowledge of what they are, or how to behave. With the new CAD systems, this concept has changed into the smart CAD objects. The smart objects will automatically provide all the data related to it: geometry, materials, specifications, price, as well as manufacturers and theoretically any related data. Creating new objects is not an easy straightforward job, and requires more programming skills than previously needed. Taking into consideration the relative difficulties in learning to modify and create new CAD objects, this might lead to a new branch of learning, as the architecture students might not only need to learn how to use the CAD packages but also how to program it in a way that makes them capable of doing what they want rather than doing what the package allow them to do.

title Cellular Texture Generator for Architectural Models
source University of Texas at Arlington, Department of Computer Science and Engineering
summary Cellular materials are used extensively in architectural settings. These materials usually have well defined geometry such as brick, stone and tiles. Patterns created with cellular materials are mostly the product of an intuitive design process that goes through cycles of synthesis and reflection until reaching final solution. Therefore interactivity is critical to intuitive designs. This paper presents a system that enables interactive creation of 3D cellular textures. It recognizes critical design areas that can have special design consideration such as edges. The system makes use of existing graphic engines and provides an intuitive interface to create patterns interactively. Rendering time is also considered through defining multiple levels of details for cells so it looks convincing in different scales. The paper presents results with an implementation of cellular texture generation system. It also shows some examples of brick walls generated with this implementation.

title Prêt-à-Construire – An Educational Inquiry into Computer Aided Fabrication
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 162-165
summary This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

title Materials in Architectural Design Education Software: A Case Study
source International Journal of Architectural Computing vol. 1 - no. 1
summary Most CAAD software in use for architectural education relies heavily on abstract geometry manipulation to create architectural form. Building materials are usually applied as finishing textures to complement the visual effect of the geometry. This paper investigates the limitations of commonly used CAAD software in terms of encouraging an intuitive thinking about the physical characteristics of building materials in the context of the educational design studio. The importance of the link between representation and creativity is noted. In order to sample the current functionality of typical software used in architectural education a case study involving 80 first year architecture students is presented.These outcomes are discussed and the possibility for new or extended software features are suggested. The paper concludes with an argument for design software that redresses the balance between geometry and materials in architectural design education.

summary Means of expression have always affected our ways of thinking. Designers, who have to interpret signs, languages, and evolution in order to translate into an organised “form” the recurring problems and values of mankind, have left thoughts, projects and wishes to the study of representational techniques. In this way, they have also disclosed a unique view of reality and at the same time a “way of being” towards the meaning of design itself. In the relationship between architecture and representational techniques, Brunelleschi said that “perspicere” was no longer just the science of optics, but also the science that contained the lines of research on geometry and shape that he was the first to exploit in design. Centuries later, in the axonometric representation advocated by De Stijl and intended for factories and industries, the object, shown in all its parts, easy to reconstruct even in the space to which it referred, revealed with extreme clarity the mass-production building and assembly materials and systems. Digital representational media make a great entrance in the heuristic process, invalidate all signs, and promote its quality. The result is an ever-changing, computerised architecture, dominated by curvilinear, wavy shapes that flow from a generative process made of the deformations, additions, and interference of different volumes.

Design education is sustained in conceptual instrumentation; it implies to recognize problematics that surpass the possibilities of an isolated or self-sufficient discipline; transdiscipline becomes essential for the understanding of the subjects.The porpuse is to generate new instruments for perception of space, combined with new visualization technologies. Anyway we must speak of all the design areas. The use of computer science has a specificity applications that are proper to each area. New technologies and the role of the new graphs in the design process, generate a new aesthetic.

summary The proposal of "Urbamedia" is to undertake the development of 3D virtual and interactive models of historical areas of Latin-American cities. The selected zone is the "Mayo Avenue" including the "Mayo Square", an historical place of the city of Buenos Aires, Argentina; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting the first experimental model of the "Mayo Square" that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. combined with a system analysis of urban activities using the “Atlas.ti” CAQDAS software.This particular use of the “Atlas.ti” software is under experimental applications to this type of urban analysis procedures; allowed us the possibility to analysed a set of activities by means of graph theory as result of a series of interviews to the people working in the area. We are also looking to include historical areas of three cities: Mar del Plata, Rosario and Santa Fe (Argentina) and eventually other cities from Latin América as Rio de Janeiro and Habana.Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulations of the environmental parameters.

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 IDEATION: METAPHORICAL EXPLORATIONS AND DIGITAL MEDIA

summary Metaphor in architecture involves two distinct paradigms of ideation and visualization: architecture as a virtual metaphor of an idea and virtual models of architecture as metaphors of an architectural intention or vision. Digital media is a powerful vehicle for the generation and expression of both paradigms. The dominant applications of digital media in architecture are drafting and computer simulations as virtual constructs of an architectural intention. This paper will focus on the us e of digital media and ideation, a design process which uses metaphor to link idea and form early in the design process.

title Virtual Menus on VRML
source International Journal of Architectural Computing vol. 1 - no. 3
summary The Virtual Reality Modeling Language (VRML) has allowed the expansion of resources and possibilities for architectural applications. In order to take even more advantage of VRML, we developed an application of virtual menus within VRML using Java Script as a first step to the creation of a Synthetic Environment Laboratory for architectural design. This paper briefly presents the criteria used to define the menus, the utilization of Visual Basic programming to allow the addition of said virtual menus to any file with extension *. wrl, specific examples of applicability of the menus developed, and how they were inserted in a methodological model of architectural design.

title A NEW APPROACH TO VIRTUAL DESIGN FOR SPATIAL CONFIGURATION PROBLEMS,
source 7th IEEE International Information Visualisation Conference, London, UK, 16-17 July 2003. http://www.graphicslink.demon.co.uk/IV03/
summary In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of Intelligent Virtual Environment, we propose an intelligent configuration system based on constraint logic programming (CLP), integrated in a real-time 3D graphic environment. This type of integration facilitates the expression of design knowledge in the VE and enables the user to interactively solve and/or refine a spatial configuration problem. In the system described in this paper, the user can visually explore configurations, but his interaction with objects of the configuration problem triggers new cycles of constraint propagation from the modified configuration to produce a new compatible solution.
