title Foundations for a Constraint-Based Floor Plan Layout Support in Participatory Planning of Low-Income Housing
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 283-287
summary We introduce the foundations of a novel approach that deals with constraint-based design methods to supporting participatory planning processes of low-income dwellings. We examine the space allocation problem inside the architectural domain on the basis of graph theory and combinatorics, providing a concise mathematical background for an implementation strategy called FLS (Floor plan Layout Support), which is analyzed here for the first time regarding this particular context of application. The philosophy underlying a design method that is mainly driven by the formulation of distinct constraints suggests to avoid the traditional procedure of first to create a yet not necessarily valid instance of the eventual design solution by directly choosing specific parameter values of its shape, and later on to evaluate its validity by confronting the designed model to a set of applicable constraints. Instead, constraint-based design poses a search procedure that operates in a space of planning-relevant constraint sets. The FLS methodology integrates some few principles of constraint-based automated reasoning with high user interactivity, into a design environment where as much dwellers as planners can collaboratively work in solving spatial organization problems of housing projects. The FLS model of application makes use of a combination of dweller-specified constraints, planning and zoning regulations, and a small library of modular space units. Constraint-based design ! methods are particularly capable of supplying efficient support for the collaborative involvement of dwellers into the architectural programming process of her/his own home. Mainly, because dwellers themselves tend to describe their space need and design intentions as a set of constraints on room quantity, space utilization, circulation system, allocation of available furniture, available budget, construction time, and so forth. The goal is to achieve an integrated tool for finding and modelling topologically valid solutions for floor plan layout alternatives, by combining user-driven interactive procedures with automatic search and generative processes. Thus, several design alternatives can be explored in less time and with less effort than using mainstream procedures of architectural practice. A FLS implementation will constitute one system module of a larger integrated system model called Esther. A FLS tool shall interact with other functional modules, like e.g. the BDS (Building Bulk Design Support), which also uses constraint-based design methods. A preliminary procedural model for the FLS was tested on Chile’s official social housing standards (Chilean Building Code – OGUC. Art. 6.4.1) which are very similar to most Latin American housing programs currently in operation.

summary Representational approaches have always played an important role in the design-driven development of built environments, the analytical study of architectural compositions and their effects. With the introduction – and successive steady development – of computer-based platforms of visualization, the professional and intellectual palette of designers, as well as researchers, have expanded considerably. Nonetheless, in recent years the opportunities for systematic scrutiny and understanding of the expressive qualities of design proposals and artefacts have all too frequently been overshadowed by high-flying conceptual developments and seductive representation modes. It is time that the objective description and unravelling of architectural compositions – so to speak the discipline of Ekphrasis in design practice, education and research – is once again given more prominence in architectural discourse and debate. The central idea behind this contribution is that, by linking instruments of design with the methods of formal composition and decomposition, renewed opportunities for representation-driven study in a scholarly context, focusing upon elusive compositional attributes and their workings, may be given a new impulse. The project that is presented here concerns a case-based explorative study into the domains of aesthetic convention and invention, making use of a variety of virtual and physical representation techniques. These include digital as well as tangible modelling and sketching approaches (separately and in combination), in conjunction with computer-based image manipulation techniques, making use of systematic data identification and denotation. The opportunities, merits and shortcomings of the computer-based and physical visualization approaches, which were applied and tested, are discussed on the basis of results and findings from the ongoing AA Variations project.

title Approach to Design Behavioural Models for Traffic Network Users - Choice of transport mode

summary Our research work concerns the development of a multimodal urban traffic simulator designed to be a tool of decision-making aid similar to a game wherein the user-player can test different scenarios by immersion in a 3D virtual city. Our approach is based on the activity-based model and the multi-agent technology. The implemented result is a hybrid simulator connecting numerical simulation and behavioural aspects coming from real data. This paper is focused on two points: firstly, we introduce how a final user (the traffic regulator) instantiates and assembles components so as to model a city and its urban traffic network; secondly, we present the use of Dempster-Shafer theory in the context of discrete choice modelling. Our approach manipulates input variables in order to test realistic representations of behaviours of agent categories in a decision-making process. The traffic modelling is based on a questionnaire elaborated from standard arrays of Taguchi. The significant variables and interactions are determined with the analysis of variance which suggests a reduced model describing the behaviour of a particular social category. The belief theory is used to take into account the doubt of some respondents as well as for the preferences redistribution if the number of alternatives changes. The effects of external traffic conditions are also quantified to choose a 'robust' alternative and to use the agents' memory.

title CNC Timber Framing – Innovative Applications of Digital Wood Fabrication Technology
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 304-307
summary The discourse on depleting natural resources and compromised environments have led to extended research on sustainable designs methods, building practices and materials. Beyond the actual performance of building products and components, research on sustainable building increasingly focuses on the long-term effects of the production, application and life cycle of building materials on the natural environment, human inhabitation and quality of life. Computer aided manufacturing technologies play a significant role not only in the transformation of design and building methods, but also in an extended discourse on cultural development. Globally available technologies connect the design and building process to a broad range of long-term ecological factors by creating a correlation between "the emergent political, economical and social processes and … architectural techniques, geometries and organization." Through this interrelationship to economy and culture, technology and its applications are also directly related to notions of place and territory as well as to fundamental ideas of ecology. The collaborative research and design study for an outdoor theater roof structure at the University of British Columbia Malcolm Knapp Research Forest at Maple Ridge, B.C., Canada, focuses on the use of digital media in prefabrication and material optimization. By utilizing small square section timber and minimizing the use of alienating connectors the research on the wood roof structure illustrates the potential of a design culture that seeks innovation in a broader understanding of ecology routed in regional culture, environmental conditions, economy and tradition. Labor intensive manufacturing techniques are redefined aided by computer controlled machines and virtual modeling of complex geometries is translated into simple operations. The result is a more sensible and accurate response to the place’s demands. In order to generate innovative design interventions that make a constructive long-term contribution to the preservation, maintenance and evolution of the environment, design needs to be based on a comprehensive understanding of its context and the distinctive qualities of the materials used. Following the example of the outdoor roof structure, this paper aims to define innovative design as work that resonates at the intersection of the fields of technology, material science, manufacturing processes, techniques of assembly and context that constitute the expanded context or complex ecology that projects need to engage. It is in design research studies like for the outdoor theater roof structure with focus on CNC wood fabrication technologies that the common design and building discourse is put to question, boundaries are explored and expanded and the collective understanding is improved towards ecological design.

title Sensitive Voxel - A reactive tangible surface
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. 525-538.
summary Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ευ = good and άπτω = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner – potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique “touch” for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

title Digital Storytelling: "Memory….. Sarajevo, my personal story"
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 337-340
summary “It was a fresh summer night, sky deprived of stars, and hardly any signs of life. After hours of waiting, well passed midnight, they finally allowed us to enter. I couldn’t see or hear much, except movements of those in front of me, but judging by intense scent of mildew and worm-like smell of earth, I realized my mile long underground adventure had begun. There was no looking back, only the brave steps ahead into my new, and hopefully, safe and fruitful future.” [ from diary95 ] Just like many teens around the world, I too kept a journal. It began with playful thoughts of a teenage girl, living in Sarajevo, enjoying life. On my fifteenth birthday, those carefree moments were soon replaced with brutal facts of life under siege: Sarajevo and its citizens had been surrounded by the Serbs who took over all the roads leading in and out of the city. Three years later, I was weeks away from graduating high school, and instead of getting excited, I wondered about my future…”Yesterday was awesome -- we had both electricity and water for eight straight hours…hooray!! You could see the lights miles away…the entire city was awake, making pies and bread, washing clothes, watching movies.” [ from diary93 ] Was I going to spend the rest of my life anticipating the restricted electric and water timetable? Would I wake up the next day to see all my family alive? Would I ever have a chance to fulfill my dreams? This project captures the process of [re]tracing steps of my personal journey of leaving Sarajevo to come to the United States and [re]constructing memories as a sequence of spatial events using the artifacts and the text from my war journals. The intent of my project is to define that line between the old and the new, and intertwine and merge its current condition with the facts and memories from the past. Although there was never a permanent “Berlin-wall-like” divider, the natural contours of the river and invisible screens of the snipers served as impermeable walls and divided the city for four years. The implied boundary seemed to be more powerful than the massiveness of the concrete barricades. Is it possible to re-condition something [building, space, soul] to be and feel the same when it had been destroyed and deeply scarred on the inside? Instead of placing banal memorials engraved with the bare facts, how can we make a tribute to a series of events—a time period that changed the fabric of the city—in a more three-dimensional experience? How can we integrate digital phenomenon in the process of the post-war reconstruction to re-trace the past while creating necessary advanced improvements for the new contemporary society? The impact that social conditions have on architecture, art, culture, and ultimately, people can be told in a universal language – digital storytelling, containing pieces of history and personal memories to create representations of time and space of the past, present or future.

title Musing Heideggerian Cyberspace
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary Where we do we make our “being?” Since our existence [being-there = Dasein] is the original place of intelligibility, fundamental ontology must clarify the conditions of having any understanding which itself belongs to the entity called Dasein. Today Dasein in increasing becoming more and more digital, in fact all activity is digital or becoming digital in one mode or another, it’s ubiquitous! On the pragmatic side corporate architecture as well as its daily interaction and transaction are all digital. With the advent of games as well as webmasters using VRML or some equivalent of it posses the questions and concerns as who will design the digital domains, graphic artists, IT personnel, game developers and where will we make our being? As architects and designers where will our “digital gesamtkunstwerk” be? Making places for human inhabitation in a nonphysical space raises interesting questions concerning presence, authenticity, adaptability, orientation, and suspension of disbelief. What kind of activities can be supported by nonphysical spaces? What will it take to support them in a socially and psychologically appropriate manner? And WHO will design them? On the applied side this ontological view is demonstrated in an Interior Design Corporate Office Design Studio that has been taught for a decade wherein students are required to develop an ECommerce, a business deemed to succeed including the Corporate Office, facility program, space planning, corporate image, interiors, graphics, webpage, and logo. The semester project has one unique design stipulation: The one major design requirement is that the “feel” of the reception has the same “feel” as the website. A phenomenological sameness…all work is accomplished with a plethora of digital media. This design process is still in its infancy.

title Road hierarchy and speed limits in Brasília/Brazil
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary This paper addresses communication during the design process and the mutations it may undergo depending on the medium of design. Three experimental observations were held with students in the context of architectural digital design studios. Each of them was performed when the students were working on a design problem, in groups of two or three, with different design mediums: cardboard mock-up or modeling software with one or two mice used for interaction with the computer. The methodology used for analysing the recorded video and graphical data is based on previous research work in the domains of collaborative communication as well as in the domain of design. It combines purely qualitative interpretation with graphical linkographic analysis. A software prototype was developed in order to allow for an interactive category assignment, exploration and interaction. Gesture, verbal language and design space are studied in order to determine their dependence on the medium and the eventual impact this might have either on the design process or on the object being designed.

summary The conceptual design of virtual spaces is creating new places in which to live and work. In consequence, new opportunities for work and employment are opening up for architects as well as for architectural educators. In response to this challenge, VIPA, a transnational virtual campus is currently being developed; it contains an e-learning and research platform for European architectural schools with a focus on virtual space design. The virtual campus integrates administrative, curricular, and communicative infrastructures, interactive, multimedia 3-D contents, and pedagogical considerations in respect of the aims, content and technologies employed. Virtual campuses are already established at most universities in the European Community, yet surprisingly e-learning is not yet widespread in architectural schools in Europe. E-learning is arguably still in an initial research phase; although there are best practice examples where e-learning is already replacing traditional study forms in other teaching disciplines. However, it has been found that although all the universities involved in the VIPA project have been involved in e-learning projects for many years, there is a considerable resistance to e-learning as being equally effective as traditional face-to-face studio teaching. Given the new virtual conditions of space design however, new contexts for learning are increasingly relevant. University curricula have developed out of local competencies, networks of teachers and researchers. These local factors need to be woven into the fabric of a transnational VIPA curriculum and supported with organizational layout, platform, user interfaces and their features. Participants will offer existing courses in virtual space design, as well as developing new ones. This offers the option for both present and future participants to adjust the VIPA courseware to suit local curricula demands, while offering a large range of courses and knowledge. An additional feature of VIPA is thus as a platform for curricula development in virtual space design. The paper reports on the VIPA project’s aims, pedagogical problems, solutions, course content and methods; it will describe prototype results from participating universities and include perspectives on its future application.

summary This paper documents a study done considering Virtual Reality (VR) as a spatial representational context which supports communication. It aims to identify whether VR could be considered as a communication medium, a tool that could be used for the successful transmission of information and messages, as well as the future form, content and use of it. That is, how does communication occur in a Virtual Environment (VE), by taking into account its visual properties and spatial parameters and under which conditions communication messages are conducted via VR systems, deriving from the one part (sender) and concluding to the other (receiver). The methods selected for this study involve observation and use of questionnaires at the end of each session. An already existing Internet-based online multi-user virtual environment has been chosen as the context where this survey will be carried out, that is the site Active Worlds, http://www.activeworlds.com, which can be accessed very easy to any computer user, in a desktop form. Firstly, we investigated the time needed, depending on the complexity per case, for a user of the VR application to get acquainted with the system. We were interested to know if the meaning that we would like to communicate had either remained the same through all the time of the experience or had been “modified” in a certain way and if so, for what reason. Another issue that was examined was the way in which the spatial context in a specific VE affects the way communication occurs. The framework of the application may influence the way the person receives a message, for example by making assumptions and references that he would not have made in a different environment- outside VR. After the end of the experience, the user was invited to describe his/ her impressions, with the communication factor being stressed, that is to mean if and at what extent VR can be characterized as a communication medium, as it is mentioned above, even for limited information and messages in general.

title A Constraint-Based Building Bulk Design Support
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
summary We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

summary The perception of space, geometry, material and the influence of light is one of the core items of undergraduate courses in architecture. In Bochum we developed and still practise a consequent system of integrating drawing and photography as analytic tools of perception and sketching, descriptive geometry, computer aided design, digital visualisation and animation as synthetic items. The versatile use of digital media in the further studies is of essential significance - especially the synthesis between architectural photography (with all its special features concerning geometrical depicting) and CAD / visualisation / animation. Special emphasis is given to techniques for simulation and immersion such as digital panorama photography, combined with computer-based vr-modelling e.g. vrml as well as using online-cad-modeling and arial photography in processes of citizen participation.

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.

summary With recent developments in communication and information technology there has been increasing research into the role and the impact of computer media in collaborative design. This paper presents a case study that compares two designers collaborating in three different types of virtual environments with face to face (FTF) collaboration. The aim of the study is to identify similarities and differences between remote locations in order to have a better understanding of the impact of different virtual environments on design collaboration. Our results show that the architects had different designing behaviour depending on the type of external representation: they developed more design concepts, and had more design iterations through analysis-synthesis-evaluation while designing FTF and in a remote sketching environment; while the same architects focused on one design concept and making the design when designing in 3D virtual worlds.

summary Structural zoning is the recognition of forms in spatial designs. It can be used by a structural designer to develop a structural system. This paper will start with the presentation of a proof that neither user action nor a two-dimensional approach -two existing approaches of zoning- are able to recognize all possibilities for the application of a structural design to a spatial design. Only full three-dimensional structural zoning is considered to be an appropriate instrument to give useful solutions. Two new concepts will be presented to overcome problems for three-dimensional zoning: (1) Geometrically Related Reducers and (2) Matrix Coupling. These concepts are first defined in a general form and thereafter the definitions are condensed into a practically applicable format. Both concepts are demonstrated when finding rectangular zones in spatial designs up to 44 separate spatial entities. They are programmed procedurally using the C++ computer language and are used for a comparison between structural designers and computer performance.

title Revitalization of Existing Buildings through Sustainable Non-Destructive Floor Space Relocation

summary The revitalization of existing buildings is gaining importance. We are facing a development where, in many cases, there is no need to design new buildings because an increasing number of existing buildings are not used anymore. The most ecological procedure to revitalize these buildings would be through a continued usage and by making few or no alterations to the stock. Thus, the modus operandi could be called a “non-destructive” approach.From the architect’s point of view, non-destructive redesign of existing buildings is time-consuming and complex. The methodology we developed to aid architects in solving such tasks is based on exchanging or swapping utilization of specific rooms in order to reach a design solution. With the aid of mathematical rules, which will be executed by the use of a computer, solutions to floor space relocation problems will be generated. Provided that “design” is in principle a combinatorial problem, i.e., a constraint-based search for an overall optimal solution of a problem, an exemplary method will be described to solve such problems.The design of the model developed is related to problems in logistics (e.g., the loading in trans-shipment centers). The model does not alter geometric proportions or locations of rooms, but solely changes their occupancy such that a new usage could be applied to the building. From our point of view, non-destructive models can play an important role in floor space relocation processes. Our examinations demonstrate that new patterns of utilization could be found through the use of this model.

summary Putting a camera close to a scale-model requires deliberately chosen abstractions and refinements in order to communicate the required architectural insights. Depending on what aspects exactly have to be evaluated (e.g. the visualisation of urban space, building blocks, façade structures, urban furniture, traffic, day and night situations, general atmosphere of a place etc.) different choices can be made for level of detail and materialisation of the scale-models. Specific computer controlled tools can be employed to gain high-precision control over model making. In this conference contribution an overview is provided of possibilities from our newly established Computer-Aided- Modelling-lab (CAM-lab). A selection of applications, made by students and researchers, will be presented. Specific choices can make or break the quality of the final presentation. Insight and knowledge of many available techniques, using the right tools and materials, can bring appropriate scenes before the camera. The input from unbiased and freely experimenting students can give happy surprises and new insights. While looking at the broad range of possibilities, inspired by innovative experiments of students in the workshop we work towards a set of best practices. Especially the integration of different digital and traditional techniques remains interesting.

summary The finding of a functional program for any kind of building involves a great amount of knowledge about the behavior of future building users. This knowledge can be gathered by looking at relevant building literature (Adler, 1999; Neufert and Neufert, 2000) or by investigating the actual processes taking place in similar environments, the latter being demonstrated e.g. by (Schütte-Lihotzky, 2004) or new functionalist approaches of the MVRDV group (Costanzo, 2006)). Both techniques have the disadvantage that the architect might assume a behavior which is seldom experienced in real life (either through lack of information or by failing to meet the building user’s expectations). What is needed is a verification step in which the design is tested on real users. We have devised a game-like environment (Figure 1a) in which it is possible to capture the behavior of future building users in order to verify the relevance of the design even at a very early stage. As result of applying our approach, we can find previously overlooked usage situations, which may be used to further adapt the design to the user’s needs.

summary Computer-Aided Design (CAD) / Computer-Aided Manufacturing (CAM) related research has been discussed since the 1960's (Ryder, G. et al, 2002, Mark Burry, 2002). Indeed, both Frank O. Gehry and Toyo Ito utilized CAD/CAM to create rich architectural form and in so doing gave birth to a new type of aesthetics. The visualization and liberalization of form space is the single most important characteristic attributable to the use of computers as a design tool. By the 1980's, Laser cutting and Rapid Prototyping techniques developed from CAM, became important new digital tools when researchers and designers discussed the development of form in architecture.
