title	Toward New Wall Systems: Lighter, Stronger, Versatile

summary	Recent developments in digital technologies and smart materials have created new opportunities and are suggesting significant changes in the way we design and build architecture. Traditionally, however, there has always been a gap between the new technologies and their applications into other areas. Even though, most technological innovations hold the promise to transform the building industry and the architecture within, and although, there have been some limited attempts in this area recently; to date architecture has failed to utilize the vast amount of accumulated technological knowledge and innovations to significantly transform the industry. Consequently, the applications of new technologies to architecture remain remote and inadequate. One of the main reasons of this problem is economical. Architecture is still seen and operated as a sub-service to the Construction industry and it does not seem to be feasible to apply recent innovations in Building Technology area. Another reason lies at the heart of architectural education. Architectural education does not follow technological innovations (Watson 1997), and that “design and technology issues are trivialized by their segregation from one another” (Fernandez 2004). The final reason is practicality and this one is partially related to the previous reasons. The history of architecture is full of visions for revolutionizing building technology, ideas that failed to achieve commercial practicality. Although, there have been some adaptations in this area recently, the improvements in architecture reflect only incremental progress, not the significant discoveries needed to transform the industry. However, architectural innovations and movements have often been generated by the advances of building materials, such as the impact of steel in the last and reinforced concrete in this century. There have been some scattered attempts of the creation of new materials and systems but currently they are mainly used for limited remote applications and mostly for aesthetic purposes. We believe a new architectural material class is needed which will merge digital and material technologies, embedded in architectural spaces and play a significant role in the way we use and experience architecture. As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the architectural space. This paper presents an ongoing research project about the development of new class of architectural wall system by incorporating distributed sensors and macroelectronics directly into the building environment. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	Between Mediation and Making CIMSp: A Technoètic Modus Operandi
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 435-442

summary	The following paper describes an ongoing research project whose goal is to define a scalable, hybrid production and deployment protocol (CIMSp) for the creation of virtual environments (VE). Ultimately, the aim is to establish a creative workflow and infrastructure that embodies architectural and urban design activity as practiced by the research unit. The objective of the present paper is to schematically outline the current state of the research and its practical and theoretical context for further development. A theoretical position will be stated which assumes that the content, tool, epistemological, and speculative realms are consubstantial (technoèsis). The practical endeavour is to create the informational and embodied temporal--spatial condition of possibility for the imaginative production of cultural artifacts. It must accommodate varying individual and collaborative forms and styles of making and no presumption of a self-enclosed and referential system is made. A critical position is particularly compelling when this production is immersed in technological modalities of making where information and embodiment are inextricably intertwined. CIMSp is based on the workflow from acquisition and creation to output and storage. The work environment is comprised of a select set of software applications and visualization technologies. Secondly, an XML-based content and information management system is under construction to ensure project quality control, rigorous documentation practices, and bi-directional knowledge feedback procedures to enable an effective and resource-full workflow. Lastly, scalability of output modalities for use in the design process and for final presentation from WWW deployment to a high-resolution collaborative work environment (CWE) is being developed. The protocol is a multiuser mode of creation and production that aims to transform the technologies and their interrelation, thus dramatically impacting the creative process and intended content. It is a digital production workflow that embodies intensive visualization criteria demanded by the end users. The theoretical and practical intention of CIMSp is to provisionally structure the collaborative creative process and enable a choreographed movement between the realms of the technologically mediated and made in the pursuit of significant digital content creation.

summary	Gehry Partners’ (GP) sculptural approach to tectonic form, with its dramatic curves, complex geometry, and idiosyncratic application of materials, seems to have redefined the limits of architecture. The development of a strong formal vocabulary has been achieved by advanced use of information technologies, including CATIA, which allows translation among various tectonic representations, both in physical and digital forms. In addition, the nature of the office has much to do with other changes in the project delivery system, such as the relationships with associate architect, manufacturers, and subcontractors. This paper discusses how new technology changes the design and fabrication process, which has evolved from GP’s milestone project, Guggenheim Museum Bilbao, and how organizational efforts to involve the industry in the design process facilitate the project. Unlike at Bilbao, in the newly-completed Stata Center GP produced all the construction documents. This shift coincided with a gradual change in which GP was becoming involved in the technical aspects of their projects much earlier in the design process. Therefore they had to invest in new working relationships with the construction team, including fabricators, manufacturers, and contractors. The approach of Gehry and his team suggests that architectural practice can be liberated from its conventional arrangements. Although it is still evolving, Gehry has achieved a holistically integrated organizational system where the architect has far more direct interaction with all aspects of design and fabrication.

title	MATHEMATICS FORMATION AND CREATIVE DESIGN
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 225-229.
summary	One of the earliest human beings desires has been to inhabit a place that may assemble beauty and functionality. Architecture and Design have been the disciplines in charge to formalize it. Their study, as well as the way they are taught have been adapted to fit the needs; and the velocity of their transformation is even greater as well as the link between design, art and technology. Creativity, in it basic generic entity, is the capability to solve appropriately and originally phrased architectural problems which involves not only space, act, environment and semiotics but with everything related to make the project able to be constructed and inhabitable. New technologies are based on complex algorithms which, by the use of simulators, achieve to produce complexity works that would have been unbelievable twenty year ago. These algorithms have a strong mathematical basis and allow to generate other working methods so as to create wonderful geometrical objects. The study of this New Geometry requires to explore and expand this field of knowledge in the Architecture studies. In order to analyze and use complex design systems to generate non linear experimental models, it is necessary the Mathematical contribution, not only at the University education stage but also at the professional life. This New Mathematics adequately focused, is able and must be an essential ally to creative design which is born with an exercised imagination in the formation stage; therefore it must aid to establish a space where knowledge and ability for architectural work can be created, synthesized and experimented. This work tries to encourage students and in relation to Geometry promotes the following aspects: (i) Inspection of new architectural spaces, (ii)Comprehension of the geometrical structure, (iii) Originality and common sense, (iv) Relation between Geometry and design of construction constitutive elements,(v) Insertion of man in the space, (vi) Conditioning of design to human body dimensions, (vii) Fractal geometries. According to what has been expressed, this proposition acquires a fundamental significance to develop a spatial vision of geometrical shapes in students, in order to stimulate the understanding of the existing relation between abstract geometrical elements and their real applications in Architecture, Geometry and Design and Art. Besides, the purpose of this work has the aim to approach knowledge at the architectural design process and to the study of shapes and mathematical models that such designs sustain , and ultimately demonstrate the importance of an academic organization that involve teachers from different disciplines.

title	Towards a Multi Agent System for the Support of Collaborative Design
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 269-280
summary	In this paper we are drafting the outline of a framework for a Multi Agent System (MAS) for the support of Collaborative Design in the architectural domain. The system we are proposing makes use of Machine Learning (ML) techniques to infer personalized knowledge from observing a users’ action in a generic working environment using standard tools such as CAD packages. We introduce and discuss possible strategies to combine Concept Modelling (CM)-based approaches using existing ontologies with statistical analysis of action sequences within a domain specific application. In a later step, Agent technologies will be used to gather additional related information from external resources such as examples of similar problems on the users hard disk, from corresponding work of team-members within an intranet or from advises of expert from different knowledge domains, themselves represented by agents. As users deny or reward resulting proposals offered by the agent(s) through an interface the system will be enhanced over time using methods like Reinforced Learning.

source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 396-403
doi	https://doi.org/10.52842/conf.ecaade.2004.396
summary	Electronic sensors, controllers, displays and actuators can significantly enhance the value of physical models as processes of use, interaction and transformation take center stage in various fields of design. These technologies allow the development of novel computer interfaces for new kinds of interaction with virtual models, and in the future they will allow new types of active building components and materials for automated construction and dynamic runtime adaptations of inhabitable environments. However, embedding programmed logic into physical objects seems to confront designers and model makers with a steep learning curve outside the domains of their traditional expertise. The variety of alternative technologies and development tools in this area has a particularly disorienting effect on novices. Some early experiences however suggest that mastery of this learning curve is easily within reach, given some basic introduction, guidance and support. It is the purpose of this paper to provide designers with a starting point for explorations into this area, to give orientation and to demonstrate some possible development approaches and results.

title	Something 's gotta give' architectural animations
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	Architectural animations are like Harry Langer, a fifty-something entertainment mogul played by best actor nominee Jack Nicholson in the film Something.s Gotta Give. They.ve been surrounded by plenty of pathetic spiritless gimmicks. And, like Harry in the film, they have suffered a heart attack. Harry did not die. Architectural animations are still around, barely. Something.s wrong with them. When Harry begins to recover, he.s surprised to find himself growing fond of a woman his own age (played by best actress nominee Dianne Keaton). This is precisely what should happen to architectural animations. They need to come to terms with more mature attitudes and approaches. This paper presents a new and different approach to architectural animations. In ninety nine percent of the cases, architectural animations have been produced at the end of the design process, just when architects or architecture students are ready to present their schemes to an audience or client group. All design decisions have been made. All aspects of the architectural solutions have been set. Tectonic qualities, lighting schemes, construction approaches, everything has been cast in stone. The animation is simply shown as a public relations gesture to broadcast to the audience that the design team is digitally savvy and uses the latest technologies. The proposition contained herein is that animations be used throughout the design process, that is, from beginning to end.

title	STUDY ON COMPUTER-AIDED DESIGN SUPPORT OF TRADITIONAL ARCHITECTURAL THEORIES
source	Technische Universität München
summary	The research presented in this thesis describes a computer-aided design support of traditional architectural theories. Traditional architectural theories in western architecture have been considered as a basis for answering the fundamental questions of architecture: proportion, symmetry, colour, harmony and so on. In particular, the aesthetic aspect of these theories has been one of many important architectural aspects, and which is concerned with the field of architecture in determining the beauty of architectural form. The most significant role of the traditional theories in architecture is to maintain unity, to avoid chaos and then to achieve harmony in a design, using some specific design principles. However, current technology-guided constructions tend to neglect often the importance of these theories due to the standardization of building elements, due to mechanically-prepared construction and the reducing completion costs, etc. Thus, this research proposes a design support system as a design assistant that gives an intelligent advice on architectural design, using analytical design- and ordering- principles of traditional theories for the optimization of the architectural design from the aesthetic perspective. To evaluate the aesthetic quality of an architectural design, this system is implemented in the AutoCAD environment, using the AutoLISP. It is applied so as to explain and develop aesthetic qualities of a design. Designs proposed by this system include optimum designs, which are based on the traditional architectural theories, and new ones which can be in future connected to information models. To do this, the definition of information about building elements is accomplished by using the neutral format EXPRESS and EXPRESS-G for such application systems. The results of the application system are presented, such as the easily generating and quickly conceptualising of an object model, the checking of the aesthetic value of the design during the various design phases, the helping to find direction during rational searching for a solution. The user can easily appreciate the usefulness of the proposed system as a set of tools for searching for rational architectural aesthetics and formal solutions at different design-stages. It is to be hoped that a new "traditional" fundamental of architecture, such as the proposed system, incorporating CAAD systems, will find its place among new technological methods in the AEC industry and so help to bridge the gap between the value of traditional architecture and CAAD systems.

title	A Computer-Aided System for Site Selection of Major Capital Investments
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	Site selection for capital investments is a crucial complex decision for owners and analysts. Difficulties are caused by the inclusion of the numerous possible sites that may qualify, multiple objectives that could also contradict each other, intangible objectives that are difficult to quantify, diversity of interest groups, uncertainties regarding external factors such as government legislations, uncertainties regarding the timing required for permitting the sites in question, and unknown construction challenges for the different sites. As such, these exercises are multi-facetted and necessitate the employment of analysts who possess in-depth knowledge in a number of fields. More importantly, a solution must satisfy a number of physical suitability criteria, as well as, meeting a number of social, economical, environmental and political requirements. Consequently, a number of specialized tools is frequently utilized to ensure reaching an optimal decision. This paper presents a new system that integrates Analytic Hierarchy Process (AHP) operations within a Geographic Information System (GIS) application to determine the optimum site for a specified facility. The system was validated through a facility for a selected metropolitan area.

summary	The course Alternatives of Design is part of an integral viewpoint that aims to prepare architects from the Master Studies Department in Computing in Architecture (LUZ), in two ways: first, by expanding their perspective about potentialities of using new digital technologies in architecture, and second, by qualifying them to apply this acquired theoretical knowledge in their professional environment. The objectives of this paper are to describe the program of this course and to show products (2003), from the introductory to the final presentation of Virtual Museums of Interactive Sculptures, orientated and supervised both at site and at a distance through the Internet. As a result of this experience, a sample was obtained of virtual museums. design and modelling that illustrates what could be understood as virtual architecture with high degree of interaction, looking for the evolution, motivation and teamwork to incorporate virtual reality non-inmersive technologies in this new architectonic approach.

title	Integrating Design and Construction with Wearable Computers
source	International Journal of Architectural Computing vol. 2 - no. 2
summary	Wearable computers can help bridge the gap betweendesign and construction. They can integrate thesetraditionally separate cultures by improving the flowof information between them. Using a wearablecomputer, design and construction personnel can nowexchange design information quickly and continuouslybetween the point of work on the construction siteand the remote design office. The improved iterationbetween design and construction and much strongerconnection between design personnel andconstruction site afforded by wearable computers maypoint the way to a new kind of integratedarchitectural process. In this study, the goal was todetermine the value of wearable computers inintegrating design and construction by measuringspecific performance characteristics.The resultsinclude findings on productivity, rework andcommunication quality. They reveal that wearablecomputers can improve communication quality andreduce rework, but may have an initially negativeimpact on productivity. These findings suggest thatwearable computers may play a key role in futurebuilding projects, helping to bridge the current dividebetween design and construction.

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. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

source	International Journal of Architectural Computing vol. 2 - no. 2
summary	This paper summarizes the major advantages ofcomponent-based design as a paradigm for handling alldesign and construction information about a buildingat every stage of design. The paper reviews some ofthe current issues that plague the building design andconstruction industry. The component-based paradigmis reviewed as a model that reunites the fragmentedbuilding industry and as a solution for dealing withvast amounts of information that accretes during thedesign-construction process. Based on interviews witharchitects, engineers, contractors and fabricators aswell as on-site documentation of construction wefeature the design and construction of the main stairin the Rosenthal Center for Contemporary Artdesigned by Zaha Hadid as a specific case study toillustrate the viability of component-based design andto highlight the obstacles challenging itsimplementation.

summary	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.

title	A FRAMEWORK FOR COMPUTER-SUPPORTED COLLABORATION IN ARCHITECTURAL DESIGN
source	University of Michigan
summary	The development of appropriate research frameworks and guidelines for the construction of software aids in the area of architectural design can lead to a better understanding of designing and computer support for designing (Gero and Maher 1997). The field of research and development in computer-supported collaborative architectural design reflects that of the early period in the development of the field of computersupported cooperative work (CSCW). In the early 1990s, the field of CSCW relied on unsystematic attempts to generate software that increases the productivity of people working together (Robinson 1992). Furthermore, a shift is taking place by which researchers in the field of architecture are increasingly becoming consumers of rather than innovators of technology (Gero and Maher . In particular, the field of architecture is rapidly becoming dependent on commercial software implementations that are slow to respond to new research or to user demands. Additionally, these commercial systems force a particular view of the domain they serve and as such might hinder rather than help its development. The aim of this dissertation is to provide information to architects and others to help them build their own tools or, at a minimum, be critical of commercial solutions.
