title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	Conjoint measurement in virtual environment: a framework
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Conjoint analysis (also called stated preference analysis) involves the use of designed hypothetical choice situations to measure individuals' preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives (product profiles) are generated and presented to respondents, who are requested to express their degree of preference for these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of product profiles. This paper describes a framework for a conjoint analysis system in a virtual environment. Product profiles are generated in a virtual environment and respondents are requested to choose in that virtual environment the product profile they prefer. Advantages of a virtual environment in this area of research include 3D presentation, improved experience and the possibility to include measurable attributes such as time and sound. This framework is a first attempt to explore the possibilities of virtual reality systems in conjoint analysis.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	Computer-Mediated Cooperative Spatial Planning
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Decision making on spatial planning problems has to integrate recent advancements on geographical information systems with a framework that supports fair, rational and efficient decision making procedures. Such a framework will assist government and businesses with the retrieval, use and reuse of information in cooperative, distributed planning procedures requiring access to spatial data. This paper gives an overview of a computer-mediated group decision support system for the World Wide Web, namely ZENO. The target is to provide intelligent assistance to human mediators and other kinds cf "trusted third parties" during the above procedures. The role of the system is to remain neutral and help assure that the interests and goals of all members of a group, regardless of their status, are respected and appreciated. In this paper, the system's features are illustrated with a retrospective model of a real urban planning example, concerning the allocation of a new technology park in the area of the city of Bonn, where more than eighty communities, local and federal authorities, and other organizations have been requested to submit their suggestions, objections and comments on a spatial planning problem.

title	Bi-directional Inference in Thermal Design
source	Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 133-143
doi	https://doi.org/10.52842/conf.acadia.1996.133
summary	This paper demonstrates a computational bi-directional energy modeling approach for building design development. Conventional simulation tools may be labeled as mono-directional in that they require a more or Iess complete design definition in order to derive performance indicators. However, in certain circumstances, it may be desirable to reverse this process: a bi-directional (or "open") inference mechanism would allow for the identification of those changes in the design variables that would accommodate a desired change in a performance indicator. The performance-to-design mapping process is an ambiguous one: the same performance (e.g. energy use of a building, temperature variations in a space) may be achieved by different design configurations (various wall and window dimensions/properties, building orientation/massing, etc.). As a result, the actual implementation of a bi-directional inference tool is a rather difficult task. The development described in this paper utilizes a preference-based approach that involves the formalization of various external or internal constraints and preferences (such as code and standard requirements, results of post-occupancy studies, individual priorities of designers and their clients, etc.) in terms of normalized numeric scales. After a brief review of the underlying technology for the implementation of the inference engine, the paper demonstrates an actual design session using a bi-directional thermal simulation tool. Specifically, a use-scenario is described in which the designer explores the tradeoffs between various design variables (glazing area, glazing type, and floor mass) in view of the resulting energy performance of a typical residential building. The paper concludes with a discussion of the potential and limitations of the bi-directional approach toward active convergence support for performance-oriented design development.

title	Integrating Shadow Casting Methodology and Thermal Simulation
source	Proceedings of the Solar ‘96 Conference. Asheville, North Carolina: American Solar Energy Society, 1996, pp. 271-276
summary	This paper describes an experiment that integrates shadow casting methodology and thermal simulation algorithms developed by the authors. The 3D shadow procedures use a polyhedral representation of solids within a Cartesian space that allows for accurate casting of shadows. The algorithm is also capable of calculating surface areas of polygonal shadows of any arbitrary shape and size. The thermal simulation algorithms – using the Transfer Function Method (TFM) – incorporate the shaded area calculations to better predict solar heat gain from glazing based on transmitted, absorbed, and conducted cooling loads. The paper describes the use of a 3D computer model to illustrate the impact of the pattern and area of shading on the visual and thermal properties of building apertures. The paper discusses the objectives of this experiment, the algorithms used, and their integration. Conclusions and findings are drawn.

summary	Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

summary	The project multimedia training "Designing Randstad" (MTDR) is an experimental attempt to introduce multimedia in education at the Faculty of Architecture in Delft. It intends to develope teachware which will learn the students the basics of Geographic Informational Systems (GIS) implementation in land use evaluation appropriate for physical planning purposes. Interaction between students and the system will enable students to learn about GIS, to design a model of the spatial development of Randstad area and to evaluate their own designs, to produce immediate graphic visualisation of the evaluation and to compare it with the evaluations of the fellow students. The project will be applied in the first year curriculum, in the course "Region" of the Department of Urban planning of the Faculty of Architecture, in the first half of the year 1997.

title	Bringing Design to Software
source	New York, NY:ACM Press and Reading, MA:Addison-Welsley
summary	In this landmark book, Terry Winograd shows how to improve the practice of software design, by applying lessons from other areas of design to the creation of software. The goal is to create software that works---really works---in being appropriate and effective for people who live in the world that the software creates. The book contains essays contributed by prominent software and design professionals, interviews with experts, and profiles of successful projects and products. These elements are woven together to illuminate what design is, to identify the common core of practices in every design field, and to show how software builders can apply these common practices to produce software that is more effective, more appropriate, and more satisfying for users. The initial chapters view software from the user's perspective, featuring the insights of a experienced software designers and developers, including Mitch Kapor, David Liddle, John Rheinfrank, Peter Denning, and John Seely Brown. Subsequent chapters turn to the designer and the design process, with contributions from designers and design experts, including David Kelley, Donald Schön, and Donald Norman. Profiles discussing Mosaic, Quicken, Macintosh Interface Guidelines, Microsoft Bob, and other successful applications and projects are included to highlight key points in the chapters. This book is for the broad community of people who conceive, develop, market, evaluate, and use software. It is foremost, of course, for the software designer, and particularly for the reflective designer---someone who is driven by practical concerns, but who is also able to step back for a moment and reflect on what works, what doesn't work, and why. At the same time, it reveals new directions and new possibilities for programmers who build software, and for product managers who bring software to market. Software users will also find the book valuable in expanding their understanding of what good software design encompasses, which will help them in evaluating, integrating, and productively using computer applications.

title	Chaos, Databases and Fractal Dimension of Regional Architecture
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 267-270
doi	https://doi.org/10.52842/conf.ecaade.1998.267
summary	Modern research on chaos started in the 60's from an incredible finding that simple mathematical equations can model systems as complicated as waterfalls. In the 70's some scientists in the USA and in Europe started to find their way through the chaos. They were dealing with different spheres of science: mathematics, physics, biology, chemistry, physiology, ecology, economy. In the next 10 years? time the term 'chaos' has become generally known in science. Scientists gather in research groups according to their interests as to chaos and secondly according to their scientific specialities. (Gleick 1996) Objects that described chaos were irregular in shape, ripped. In 1975 Benoit Mandelbrot called them fractals. Fractal dimension that described fractal objects was also his invention. Fractal dimension is a way to measure quality: the degree of harshness, uneveness, irregularity of a given object. Carl Bovill (1996) showed how one can use fractal geometry in architecture and designing. This very fact made me try to use fractal geometry to deal with regional architecture. What or who is the degree of regionality of a given object to be for? A specially qualified person is able to state it nearly automatically. However, regionality is in some sense an unmeasurable feature. While dealing with data basis or checking particular projects, creation of procedures of automatic acquiring information concerning regionality is becoming a necessity.

title	A knowledge-based model for developing location strategies in a DSS for retail planning
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Most DSS for retail planning are based on impact assessment models to support the evaluation of plan scenario's. This paper introduces a complementary knowledge-based model to support also the earlier stage of formulating plan scenario's. An analysis of the retail planning problem reveals the main lines of the strategies adopted by most Dutch planners and retailers to achieve their goals. A basic strategy that seems to be appropriate in most problem contexts is formulated in the form of a set of decision tables. Each decision table or system of decision tables specifies for a problem area decision rules to identify and analyse problems and to formulate possible actions. The model is implemented in a DSS where it is used in combination with quantitative impact assessment models. A case study in the area of daily good facilities demonstrates the approach. The major conclusion is that the knowledge-based approach and in particular the decision table technique provides interesting possibilities to implement planning task structures in a DSS environment.

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.

title	Spatial Knowledge Acquisition from Maps and Virtual Environments in Complex Architectural Space
source	Proc. 16 th Applied Behavioral Sciences Symposium, 22-23 April, U.S. Airforce Academy, Colorado Springs, CO., 1996, 6-10
summary	It has often been suggested that due to its inherent spatial nature, a virtual environment (VE) might be a powerful tool for spatial knowledge acquisition of a real environment, as opposed to the use of maps or some other two-dimensional, symbolic medium. While interesting from a psychological point of view, a study of the use of a VE in lieu of a map seems nonsensical from a practical point of view. Why would the use of a VE preclude the use of a map? The more interesting investigation would be of the value added of the VE when used with a map. If the VE could be shown to substantially improve navigation performance, then there might be a case for its use as a training tool. If not, then we have to assume that maps continue to be the best spatial knowledge acquisition tool available. An experiment was conducted at the Naval Postgraduate School to determine if the use of an interactive, three-dimensional virtual environment would enhance spatial knowledge acquisition of a complex architectural space when used in conjunction with floor plan diagrams. There has been significant interest in this research area of late. Witmer, Bailey, and Knerr (1995) showed that a VE was useful in acquiring route knowledge of a complex building. Route knowledge is defined as the procedural knowledge required to successfully traverse paths between distant locations (Golledge, 1991). Configurational (or survey) knowledge is the highest level of spatial knowledge and represents a map-like internal encoding of the environment (Thorndyke, 1980). The Witmer study could not confirm if configurational knowledge was being acquired. Also, no comparison was made to a map-only condition, which we felt is the most obvious alternative. Comparisons were made only to a real world condition and a symbolic condition where the route is presented verbally.

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	Open Design Environment (ODE), the concept of which was proposed in 1991, is a platform on computers to support synthetic to proceed design. We have applied ODE in practical use of design, design review and presentation to make collaboration by using CG in design participants. Recent linkage between LAN and Wide Area Network, just as the Internet, gave ODE a new progress to make wide area collaboration. It leads to generate the concept of Network ODE (NODE). However, we have found some problems on system to proceed the wide area collaboration by using ODE’s Design Tools. Since they are developed on the specific computer system, they can not correspond to the wide area collaboration on various network environments. As a result, the re-arrangement of design environment and the development of Design Tools are needed, which are rather flexible and general purpose, i.e. independent of machine sort and network adaptive. In this paper, to proceed collaboration in a designer group, how to create the system of NODE is demonstrated with the new Key Technologies of network and CG.

title	Methods to assist the design of road surfaces with a reservoir structure: To improve flood risk management
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Reservoir road surfaces can be seen as equipment of the future, in that they have two functions in the same structure (circulation and hydraulic functions). They can thus be laid without immobilising land, which is very expensive and prized in urban areas. Furthermore, they enable the limitation of the flow or volumes of running water, and thus help control rainwater, resulting in better flood risk management. The questions asked by drainage designers are how can we design these structures in the best way? How are they going to work for different types of rain (rain from storms, prolonged winter rain ....)? As for the public administrators, they wonder how a series of areas equipped with this type of technique (total flow management) would work. By solving this latter problem, we could really arouse interest in flood risk management. Given the diversity of structures possible for reservoir road surfaces (regulated, non-regulated, draining surface, dispersion surface...), we suggest comparing design and simulation methods, taking into account the measurement and total flow management problems mentioned above. So as to validate these comparisons and to give some directions concerning the use of one or the other methods, we use flow-metre measures on two different sites in Lyons. One of these sites is a car- park on a tertiary activity zone on the La Doua campus in Villeurbanne, the other a refuse dump in the Greater Lyons area in the town of Craponne. They are both interesting as they have different features. The first is non-regulated downstream and is used on a car-park for light motor-vehicles. The other is regulated and the traffic on it is made up of lorries. These sites will be described in this article.

source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 371-380
doi	https://doi.org/10.52842/conf.ecaade.1996.371
summary	This paper presents some of the results of my work in the area of architectural education and color application. "Constructive Learning" techniques are the framework within which a course in color theory and application has been developed for architectural students and professionals. Constructive learning theory designates three main learning phases: introductory, advanced and experienced; each of which has a unique set of requirements that must be addressed by those seeking to teach or develop meaningful tools for a given task. The introductory level is represented by those who posses little if any prior skills or knowledge in the subject area. Here it is advantageous to carefully guide the knowledge acquisition process in order to help build a knowledge foundation upon which a personalized learning process can take place. Advanced students are those that are ready, through a more focused, context related approach, to expand their capabilities. Finally, experienced learners can be defined as those capable of critically applying and innovatively using the knowledge, skills and tools that they have obtained through the introductory and advanced phases of the learning process. Because computers introduce the issue of color at a much earlier stage of design than might previously have been the case, a new set of skills and tools are needed. The proposed course seeks to define an appropriate learning methodology for designers that can provide them with not only knowledge of the subject area being covered, but also skills with which to approach it.

title	EFFECTIVENESS OF MODELS
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	Architects use many types of models to simulate space either in their design process or as final specifications for building them. These models have been proved useful or effective for specific purposes. This paper evaluates architectural models in terms of five effectiveness components: time of development, cost, complexity, variables simulated and ecological validity. This series of models, used regularly in architecture, are analysed to finally produce a matrix that shows the effectiveness of the different models for specific purposes in architectural design, research and education. Special emphasis is given to three specific models: 1/10 scale, full-scale and computer generated.

summary	There are many of us trying to make place for CAAD in a natural way in the Curriculum of the Architect school. We would like to make CAAD useful to the students already during their studies. Even if we have the support of our collegues for running courses there is very often no space in the timetable. And even if we have all the entusiasm of our students it is hard to practice your CAAD knowledge on projects where it is not asked for. The education of architects in the use of computers has lead me to try to find "the roots of education of architects" in general. A collegue of mine in a bookshelf of course litterature in Informatics found and put into my hands "Educating the reflective practitioner" by Donald Schön. It lead to an interesting process of personal reflection and discussion within our CAAD team. We think by the way that the theme of the conference points to the heart of the message in Donald Schöns book and we are inviting him as a key note speaker at the Conference.

summary	The existing system of architectural education ( including computer ) as has shown practice has appeared not absolutly perfect. It not capable to dynamic changes, active introduction of a new engineering and computer technologies, to realization about of the inquiries of a modern time. It suggest of a way of search of new models of computer training. The computer education is represented by us as certain a universal system, which permits to solve the problem of arcitectural education at a higher level. The opportunities of computers and computer technologies at such approach are used as means of increase of efficiency teaching and training. The orientation goes on final result: a opportunity to generate of the creative decisions by learnees, based on attraction of received knowledge and use for their realization of arsenal of practical skills and skills. The system represents not only certain set of experiences elements, necessary and final result sufficient for achievement, but also quite certain interrelation between them. It means, that the knowledge from a initial rate " The Introduction in computer training" must be secured and transformed for utilization in special rates and through them- in practice. The functional nucleus of the software package of such universal system is under construction as opened, apparatus an independent system. A central part of a system is a database, the structure of which is uniform for all other modules and side of enclosures. The conceptual model of a system is under construction on principles structure idea, visualization, multimedia. The listed principles are realized in model so that to encourage the user to independent creative work.
