title A Web-Based Virtual Reality Model for Preliminary Estimates of Hi-Rise Building Projects
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Cost estimating of a construction project at its early stage is considered to be very important task since it will be used as a base to commit or otherwise not to commit funds to that project. Preparation of a reliableand realistic preliminary estimate to aid the decision makers to commit funds for a specific project is a complicated assignment. Traditional methods and operations produced unsatisfactory aid due to lack ofaccuracy especially in the pre-design stage of a project. This participates in the increase of percentage of bankruptcy in the construction industry, which has dramatically climbed up and ranked as 15 percent of thewhole bankruptcies claimed in Canada (Statistic Canada 1998). This paper presents a methodology for developing and a Web-based model to automate preliminary cost estimates for hi-rise buildings. This is achieved by integrating a database with design drawings in a Virtual Reality (VR) environment. The model will automatically generate preliminary estimates after modifying a 3D CAD drawing. It provides the user the option to visualize and simulate the drawing and its cost data through VR environment. Having done that, it will allow owners, architects and cost engineers to view a constructed building project, change its geometric objects and shapes, and accordingly generate a new conceptual cost estimate.

title Can Doors and Windows Become Design Team Players?
source Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 3-22
summary In an architectural design session, suppose design objects such as doors, windows and rooms can look after themselves, what kind of recommendations would a designer get? What is the nature of a design environment that facilitates such interactions? Where would a design object acquire the knowledge that allows it to interact intelligently? How would such localized recommendations be aggregated to support global design decisions made by the designer? This paper investigates these questions through the notion of objects as agents in design.

title Urban Sprawl Modelling: Combining Models to Make Decision
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary Urban sprawl is frequently associated with the idea of an unsuitable development, leading to increasing economic, social and environmental problems. Moreover, its control is difficult because multiple patterns (concerning numerous traditional urban planning fields) overlap. In order to understand the sprawl process and to manage its consequences, it must be simplified. The construction of a decision making tool appears then interesting. The GIS-based tool presented here is being developed incollaboration between the urban planning agency of Belfort and the laboratory of geography of Strasbourg. It requires three steps: 1. quantification of the sprawl (how much areas are involved in theurban sprawl process?); 2. location of the sprawl (where are the areas defined in the first step?); 3. differentiation of the sprawl (what are the areas located in the second step?). Of course, the successionof the three stages makes the use of the complete model more complex. So, a global ergonomic user interface is being developed within the GIS, allowing to modify each parameter and to play easily numerous simulations.

summary The cyberPRINT is a fully immersive, interactive virtual environment that is being generated in rea-timebased on physiological data readings of a human body. In other words, the cyberPRINT is based oncreating interfaces between physical and digital spaces and between biology and informationtechnologies. The cyberPRINT is also an event, wherein a performer is connected to the cyberPRINTgenerator to create a self-sustaining feedback mechanism. Although using the body to electronicallydrive music and media events is not new, most of these works have paid little or no attention to thepotential of interactive 3D virtual environments. Nor have they been so technologically advanced,interdisciplinary intensive (involving architecture, choreography, modern dance, music, bioengineering,medicine and computer science), or architecturally focused as the cyberPRINT.This project covers a wide and fertile territory that goes from the very technical and design oriented tothe very theoretical and interdisciplinary. This paper is intended to (1) expand what has been alreadypublished about this project (Bermudez et al 2000a) and (2) establish potential areas for discussionbefore and after the performance

title Evaluating the Use of a Web-Based Collaborative Interactive Digital Model (CollABITA) in Supporting the Urban Design Approval Process1
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, III.1-III.15
summary This research, after analyzing the Urban Development Approval Process in its functionalities and methodologies, is showing the key points at which the process might be supported by new computer technologies, and it establishes a web-based Collaborative Interactive Digital Model (CollABITA Model) that relates and facilitates the graphical representation of the urban design process with some elements of the methodological approach. The CollABITA Model will dramatically facilitate the idea of broadening public participation, and indirectly by this, also collaboration. This new web-based support tool, is focusing on how new Informative Computer Technologies can be used in order to have a more co-operative design process. By utilizing the enormous potential of Internet for informing the process, and software for visualizing its products, the Model will provide an effective support, which will be able to deliver information in various forms to the Designers, Developers, Decision Makers, Agencies and the final user (the Citizens). The Model is concerned with the big challenge of supporting the urban design approval process itself, by exploring different kind of visualizations and communication tools, rather than producing a guide for carrying out the design. CollABITA Model is based on the existent framework structure of the extranet tool already available. Then, more then those, CollABITA Model will try to solve, by adding technical and collaborative functionalities, those issues that are characteristics in the urban design process and that are not jet solved by using one of the software .

title Digital Design - Research and Practice
source Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1 / Tainan (Taiwan) 13–15 October 2003, 464 p.
summary The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title Generative Design: Rule-Based Reasoning in Design Process
source International Conference on Generative Art
summary As emphasized by Professor Soddu’s series of pioneer works on generative design, the fundamental theoretical base can be generallyconsidered as a design process that generates design by the initiation, developing and manipulation with designers’ objectives as well as theirassociated set of rules. This process is, in a broad sense, a reasoning process that follows the rules being set forth. In many cases, the rules arecommon logic that governs our reasoning, while in others they are more special rules that restrict the generating process to a confined space.Computer assisted generative design has made impressive progress over the past decade, along with the rapid growing capacity and speed ofcomputers as well as development and discovery of rules, rule setting and effective manipulating schemes and algorithms. After manyimpressive progress and remarkable results has demonstrated from time to time, however, theoretical foundation of such design approach, orthe significance of awareness of such approach has not been thoroughly treated, recognized and discussed, not to mention clearly understood.

title CyberQuest Prospector (CQP):A Guide for the Evolutionary Discovery Process
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary CyberQuest Prospector (CQP) is a tool to guide an individual or team through the evolutionary process of finding better approaches to a particular problem, project, program, plan, or design. This prospectingprocess can involve, for example, new definitions, different data, altered evaluation techniques and new ideas and actions on many other topics. CQP involves a five step process. At step zero all the requisite historical background knowledge is entered. This knowledge is divided into topical areas or statements. In step one the team updates the various knowledge statements in the system and then assigns a "maturity" to them. The team then adds any new statements (step two). Next, (step three) the team makes decisions on actions to be undertaken and also on the external factors likely to be "in play" in the upcoming time period. After that period (step four) the team records the results and rates the "success" achieved. CQP subsequently changes the associated knowledge statement confidences. In the last step the clock is advanced. The ultimate result is a set of definitions, data, relationships, experimental techniques, issues,implications, and even personality traits in which some degree of confidence has evolved. The CQP process is demonstrated here with an urban transportation planning example involving such diverse topics asplanning/analysis techniques, data collection methods, and procedures for working with advocacy coalition networks.

title New Expectations: City Modeling in the Internet Age
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 97-100
summary The first part of this paper tries to give an overview over the different aspects of city modeling. After a short history on city models the paper starts with a categorization of the different “types” of city models. We try to explain the various aspects involved in the creation of a city model and the problem of maintaining a city model. Then the paper shows the example of two computer models of parts of the same European city which have been created in two different ways. The first version of this computer model tries to use as many automatic or semi automatic procedures as possible to create the model. In the paper examples of these differentprocedures are given - from the automatic creation of the buildings itself, its roofs, and the surrounding terrain to the automatic cleaning of texture photos of the façade. The second version shows a model, which has been done with just a few automatic procedures and a lot of human effort (mainly students). The paper describes the limitation of both techniques and tries to give an outlook towards the combination of these methods. We will also show the importance of internet techniques in the use and presentation of computer city models.

title The Glass Chair - Competence Building for Innovation

doi https://doi.org/10.52842/conf.ecaade.2002.180
summary This paper tells the strange tale of a glass chair. Creating a glass chair might seem a perverse – maybe impossible – enterprise. After all, chairs are normally held together by moment connections, such as those joining the legs to the seat. Glass is a notoriously bad material for forming moment connections; it is brittle, and quickly snaps if you subject it to bending. But there are advantages to such startling formulations of design problems. They force you to challenge conventional wisdom, to ignore standard prototypes, and to ask interesting new questions. How might you design a chair without moment connections? How might you do so without making the result impossibly heavy? How would you built it? And what interesting qualities might such a chair have? These were questions investigated in the design project pursued jointly by students at an American and a Portuguese school, in collaboration with glass and molding fabricators. The students explored many possibilities, and in doing so learned a great deal about chairs and about the properties and potentials of glass. The final project is a particularly elegant outcome of their investigations. It is created from just two curved pieces of glass, which held together by metal tie-rods. In the end, the finished glass chair looked just like the initial computer visualizations.

title Fabrication with Residual Wood through Scanning Optimization and Robotic Milling

doi https://doi.org/10.52842/conf.ecaade.2024.1.025
summary The project deals with the use of residual wood of tree stumps and roots through scanning, optimization and robotic milling. Wood logging residue makes up to 50 percent of the trees harvested biomass. (Hakkila and Parikka 2002). Among prevailing strategies is leaving residue on site, and recovering residue for bioenergy. (Perlack and others 2005). The project explores the third strategy, using parts of the logging residue for fabrication, which may reduce the overall amount of wood logging volume. Furthermore approach aims for applying residue in its natural form and taking advantage of specific local characteristics of wood (Desch and Dinwoodie 1996). The project applies the strategy on working with stump and roots of an oak tree. Due to considerations of scale, available milling technics and available resources, chosen goal of the approach is to create a functioning chair prototype. Among the problems of the approach is the complex shape of the residue, uneven quality of wood, varying humidity and contamination with soil. After cleaning and drying, the stump is scanned and a 3D model is created. The 3D model od a stump is confronted with a 3D modelled limits of the goal typology (height, width, length, sitting surface area and overal volume of a chair) and topological optimization algorithm is used to iteratively reach the desired geometry. Unlike in established topological optimization proces, which aims for a minimal volume, the project attempts to achieve required qualities with removing minimal amount of wood. Due to geometric complexity of both stump and goal object, milling with an 6axis industrial robotic arm and a rotary table was chosen as a fabrication method. The object was clamped to the board (then connected to a rotary table) in order to provide precise location and orientation in 3D space. The milling of the object was divided in two parts, with the seating area milled in higher detail. Overall process of working with a residual wood that has potential to be both effective and present aesthetic quality based on individual characteristics of wood. Further development can integrate a generative tool which would streamline the design and fabrication proces further.

summary After more than a century of domination by neo-Darwinian theory, biological thought is beginning to giveincreasing recognition to developmental theory. Amongst other reasons, this recent widening ofperspective is grounded on the incompleteness of the neo-Darwinian perspective in providing modelsfor the invention of novel forms or species and individual development. Evolutionary design theory hasdrawn much of its inspiration from evolutionary biology and consequently shows analogous flaws. Thispaper demonstrates an adoption of biological developmental theory to the field of design theory in orderto fill the corresponding gap. As natural developmental processes are based on the development ofcellular units, which form composite structures, this paper employs the cellular model as a means for thedevelopment of a corresponding design and construction theory. The discussion of this approachincludes possible linkages between morphologic and behavioral attributes of tissues with implicationsfor self-assembly, growth, healing and self-reproduction of man-made structures.

summary During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi-EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary On a number of occasions after telling people about Corporate Design Foundation and what we do, their reaction is “well, business now understands the importance of design, right?” The answer is yes and no. There is, as they say, good news and bad news. A growing number of senior business executives do understand the possibilities of design. But many still do not. Unfortunately, the majority of mid-level managers do not. While there has been an increasing amount written about design in the business press, there has also been an equal amount in the general press which is misleading or just wrong. There is a great deal more to do.

summary Membrane packaging has been the main feature of the earliest prototypes of transformablearchitecture. Similar concepts of spatial transformation are encountered in the origami art where aplanar paper surface, after folding, transforms to a 3-dimentional object. The geometric configuration ofcreases on a sheet of paper before folding, as well as the topological properties of 3D origami papermodels, have been recently addressed, and can be used as a guide for the design of new forms.Because membranes in general can be considered surfaces of minimal thickness, principles of theorigami art and math can find applications in the conception and design of transformable membranestructures for architecture. This paper discusses how computer visualization can be used to explorethe potential application of ideas borrowed from the origami art in the conceptual design oftransformable structures. A two-case study that shows how origami math is integrated in the computervisualization of a potential architectural application is included. The same study also shows thatanimated simulations of the transformation process during folding can identify problems in the initialgeometric conception of an origami type structure, and can be used for further morphologicalexplorations.

title Use of Cadastral Data for the Development of Spatial Decision Support Systemsfor Coping with the Consequences of Natural Disasters
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary This paper investigates the potential usefulness of cadastral data to form the core part of databases of Spatial Decision Support Systems [SDSS] that are capable to support decision-makers in dealing with emergency situations, such as earthquakes, floods and fires. Particular emphasis is given on how those data can be used to generate information that is necessary to planners and decision-makers when they cope with natural disasters at every stage of the development of the disaster: before the occurrence (planning and preventive measures), immediately after occurrence (short term measures), and well-after occurrence (medium and long term measures). This investigation is conducted using the Municipality of Magoula, Attica, Greece, as a case study area. This municipality is situated in the greater Athens area and was struck by the earthquake that occurred there in September 1999. Within the scope of the project, wehave used cadastral data about the study area and data recorded by the inspection teams in order to set-up a prototype SDSS database that could facilitate planning and decision-making in such a situation. Then, we have used that prototype to generate scenarios and information about typical tasks that are performed during emergency situations. The advantages that are realized from the integration of such data and information technologies are described and assessed, particularly, in comparison with the traditional approaches that are used in such situations.

summary This paper deals with the use and evaluation of daylighting simulation tools in relation to a complex urban environment. The environment concerned is one commonly found in city centre areas where the proximity of buildings leads to the creation of ‘urban canyons’; the result of this is that assessment and simulation of daylight requires a more sophisticated approach than for other situations. In urban areas building layout is the most important factor effecting daylight, sunlight and solar heat gain reaching a building. It also affects sunlight in open spaces, ventilation, shelter and the dispersal of pollutants. In order to produce a more realistic understanding of the dynamic effects of daylight, there is a need not only for the research and development of advanced CAD and lighting simulation tools, but also of the study of possible alternative methods in their application. In the work reported in this paper, an attempt has been made to move the focus of lighting and daylighting simulation from the scale of a room to that of a whole building; the building itself being surrounded by its specific urban environment (including its microclimate). The study evaluates if there is sufficient evidence that it is possible with such complexity to reach reliable computation results after executing the simulation. The case study presented uses a 4D model of an urban canyon to investigate the sensitivity of such a complex simulation system. It can also be used to find ways to analyse and predict how daylight is reflected, refracted, scattered, diffused, polarised, diffracted and absorbed as it traverses an urban environment.

title ACADIA 2002 [Conference Proceedings]

summary The 2002 ACADIA conference finds digital tec_nology ubiquitous as the Association for Computer Aided Design in Architecture moves into its third decade. The organization of ACADIA is on the threshold of restating its mission. After 20 years, many of the organization’s initial objectives have been achieved. ACADIA members have been instrumental in the development of design software, and in bringing computers and digital technology into architectural practice and design school curriculum. At first, ACADIAns faced the debate over the appropriateness and utility of digital technology in the disciplines of architecture, planning and building science. Today the use of computers and information technology is widely accepted by architects and CAAD and digital technology have brought profound change to design practice. The debate in ACADIA has long since moved from "should we use this technology" to "how", "for what" and "why". Now that many practitioners, learning institutions and professional organizations have taken up the call, ACADIA must restate its mission, if it wishes to remain “distinct”. This does not mean that the work of ACADIA is complete. Much remains to be done and much more needs to be improved. ACADIA’s Mission Statement places particular focus on “education and the software, hardware and pedagogy involved in education.” And “(t)he organization is also committed to the research and development of computer aides that enhance design creativity, and that aim at contributing to the construction of humane physical environments.” These are the areas that continue to evolve, grow and provide for ACADIA’s continued relevance. The ACADIA 2002 conference theme reflects the state of digital technology’s application to the discipline, as much as it refers to ACADIA’s future. With the general acceptance of digital technology and CAAD, we have arrived at a place where the work of great interest and relevance lies in the space between what is digital and what is analog. The environments of real space and cyberspace have in a very short time become so intertwined that the space between real and virtual (not to be confused with reality and fantasy) is becoming indistinguishable. You cannot eat, travel, use public utilities, bank, shop, vacation or recreate without at the very least coming into contact with or passing through information space. The landscape between these two environments has become a cultural phenomenon for those societies with access to the Internet and information networks. And while the computer and World Wide Web have empowered individuals, the collective impact of the technology holds all the potential and problems that similarly emerged in other technology induced landscapes. Consider this last point in the context of ACADIA’s stated mission to “enhance design creativity while contributing to the construction of humane physical environments.” And you can see why many of the 260 initial submissions to this conference were in the area of design artifacts and design methodology, providing evidence that ACADIA’s mission remains relevant and in accord with the trends of research and professional creative activity.
