title	Using a Spatial Microsimulation Decision Support System for Policy Scenario Analysis
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 177-191
summary	This paper discusses the potential of a spatial microsimulation-based decision support system for policy analysis. The system can be used to describe current conditions and issues in neighbourhoods, predict future trends in the composition and health of neighbourhoods and conduct modelling and predictive analysis to measure the likely impact of policy interventions at the local level. A large dynamic spatial micro-simulation model is being constructed for the population of Leeds (approximately 715,000 individuals) based on spatial microsimulation techniques in conjunction with a range of data, including 2001 Census data for Output Areas and sample data from the British Household Panel Survey. The project has three main aims as follows: (i) to develop a static microsimulation model to describe current conditions in Leeds; (ii) to enable the performance of ‘What if?’ analysis on a range of policy scenarios; and (iii) to develop a dynamic microsimulation model to predict future conditions in Leeds under different policy scenarios. The paper reports progress in meeting the above aims and outlines the associated difficulties and data issues. One of the significant advantages of the spatial microsimulation approach adopted by this project is that it enables the user to query any combination of variables that is deemed desirable for policy analysis. The paper will illustrate the software tool being developed in the context of this project that is capable of carrying out queries of this type and of mapping their results. The decision support tool is being developed to support policy-makers concerned with urban regeneration and neighbourhood renewal.

title	FABRICATION: EXAMINING THE DIGITAL PRACTICE OF ARCHITECTURE
doi	https://doi.org/10.52842/conf.acadia.2004
source	Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 09696665-2-7] Cambridge (Ontario) 8-14 November, 2004.
summary	We are presenting design ideas, technical innovation, and fabrication expertise that address crucial issues. Authors investigate how to effectively design and practice architecture with automated prototyping and manufacturing. We want to understand where this might lead, and how it might change the nature of architecture itself. We are just beginning to discover the opportunities to be found in integrating automated fabrication within the practice of architecture. At the same time, the new century has brought very mixed perspectives on confident Modern progress. A cautious scrutiny of 'innovation' is needed. Fabrication is an old word with the straightforward meaning, to make. The roots of the word lead to the origins of architecture. Making has been considered a virtue by ancient writers and modern politicians alike. Fabrication (and homo faber, 'one who makes') have served as fundamental terms that constitutions and contract laws have been built upon. Shaping and working with materials is at the core of Western civilization. However at a point in human history where nature is steadily being replaced by human artifice, the consequences of making are far from simple. Whether for good or ill, our new fabricated environment is transforming the world.

title	Visual Knowledge Transfer between Planners and Business Decision Makers
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 193-208
summary	The transfer of knowledge between planners and business decision makers can be improved when planners combine traditional visualizations with business knowledge visualizations. Today architects and urban planners use visualization methods such as sketches, diagrams, drawings, renderings, models and animations to illustrate their projects. While spending an enormous amount of time to illustrate a project, almost no time is used to illustrate business relevant information that decision makers need (i.e., revenue models, risks, return on investments, project phases). Consequences are information overload, misinterpretation or even misuse of information. Juxtaposing the visualizations that planners and decision makers use reveals a major gap: Both groups use different visualization types and are not familiar with the visualization types of each other. This paper stresses the importance to expand the visualization types of planners with business knowledge visualizations. First, it discusses the functioning of visual representations for the transfer of knowledge. Second, it introduces a general knowledge visualization framework. Third, it illustrates examples from an innovative office that improved knowledge transfer with decision makers in urban planning projects. We found that combining traditional visualizations with business knowledge visualizations reduces the information overload, prevents misinterpretation, increases the information quality, improves communication and as a consequence improves decision making. We found that decision makers pay extra for these visualization types, which therefore is a new source of income for planners. The results have implications for the education of future architects.

title	Mindful Spaces: Computational Geometry and the Conceptual Spaces in which Designers Operate
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 611-624
summary	Combinatorial computational geometry, while dealing with geometric objects as discrete entities, provides the means both to analyse and to construct relationships between these objects and relate them to other non-geometrical entities. This paper explores some ways in which this may be used in design through a review of six, one-semester-long design explorations by undergraduate and postgraduate students in the Flexible Modeling for Design and Prototyping course between 2004 and 2007. The course focuses on using computational geometry firstly to construct topologically defined design models based on graphs of relationships between objects (parametric design,) and concurrently to output physical prototypes from these "flexible models"(an application of numerical computational geometry). It supports students to make early design explorations. Many have built flexible models to explore design iterations for a static spatial outcome. Some have built models of real time responsive dynamic systems. In this educational context, computational geometry has enabled a range of design iterations that would have been challenging to uncover through physical analogue means alone. It has, perhaps more significantly, extended the students' own concept of the space in which they design.

title	Creating and Using Virtual Cities
doi	https://doi.org/10.52842/conf.ecaade.2004.580
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 580-585
summary	City modelling is a topic which has been on the agenda for a long time and two main approaches from different angles in this field can be identified. GIS experts have attempted over the years (in collaboration with programmers) to build information systems for cities by means of combining graphical information with related metadata. Architects also started to get involved in this field. However, they were mainly interested in the spatial aspects of a city model and created their own “city models” for different purposes. Today crucial questions concerning the creation itself are resolved, the vision of implementation into daily work becomes more and more important. In other words: “what to do” with the accumulated data. This paper intends to identify the core role of the architect in the field of 3D-city modelling.

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This proposal addresses the following topic of a doctoral thesis in progress: The Evolution and Development of Digitized Processes for the Research and Maintenance of Small Town Patrimonies, School and Architecture and Urban Design, University of Buenos Aires, co-directed by architects A. Montagu and R. Gutierrez. The research has been based on the town of Mercedes, Province of Buenos Aires, Argentina, symbols of Buenos Aires.s cultural heritage. At this stage, we are looking for alternative methods to support a project of patrimonial preservation that would help define future landscapes of small towns, and, at the same time, would have minimal or positive environmental impact. This analysis proposes reflexive studies of the paradigms affecting the environment and the feasibility of the project, with the intention of utilizing the concept of .ecoproject.. Therefore, the crucial assistance of specific digital systems, from which evolution is analyzed, supports and enhances the efficiency of the proposed goal. New and broad research opportunities are opening up in this field.

title	What’s Happening to Architectural Sketching? - Interviewing architects about transformation from traditional to digital architectural sketching as a communicational tool with clients
doi	https://doi.org/10.52842/conf.ecaade.2022.1.389
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 389–398
summary	The paper discusses 23 interviewed architects in practice about the role of traditional and digital sketching (human-computer interaction) in communication with the client. They were selected from 1995 to 2018 (the interval of graduation) from three different countries: the Czech Republic (CR), Slovakia (SR), Netherland (NR). To realize three blending areas that impact the approach to sketching: (I) Traditional hand and physical model studies (1995-2003). (II)Transition form - designing by hand and PC (2004–2017). (III) Mainly digital and remote forms of designing (2018–now). Interviews helped transform 31 “parameters of tools use” from the previous theoretical framework narrowed down into six main areas: (1) Implementation; (2)Affordability; (3)Timesaving; (4) Drawing support; (5) Representativeness; (6) Transportability. Paper discusses findings from interviewees: (A) Implementation issues are above time and price. (B) Strongly different understanding of what digital sketching is. From drawing in Google Slides by mouse to sketching in Metaverse. (C) Substantial reduction of traditional sketching (down to a total of 3% of the time) at the expense of growing responsibilities. (D) 80% of respondents do not recommend sketching in front of the client. Also, other interesting findings are further described in the discussion.

title	Diagram as media of design speculation. The productive ambiguity of Voronoi diagram.
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 394-399
summary	In contrast to the traditional models of design processes based on the abstract manipulation of objects, the new digital media arena provides to architecture an interesting territory of experimentation characterized by non-linear design processes capable to articulate spatial requirements and social organizations on time. In this sense, the speculation through a diagrammatic system proposes a change focused on design as a network of processes. According to this, this paper purpose is to investigate the validity of these arguments through the use of Voronoi Diagram as design tool into the context of Create_Space research agenda of the AAD[R]L 2004-2005.

summary	The educative proposal was based on the summary attained through experiences piled up during the 2 last semester courses, 2/2006-1/2007. This proposal corresponds to a mix of methodology (by personal attendance / by internet). Founding on the Theory of the Game (Eric Berne 1960) and on different theories such as: Multiple intelligences (Haward Gardner 1983), Emotional Intelligence (Peter Salowey and John Mayer 1990, Goleman 1998), Social Intelligence (Goleman 2006), the Triarchy of Intelligence (Stemberg, R.J. 1985, 1997), “the hand of the human power”, it´s established that the power of the voice, that of the imagination, the reward, the commitment and association produce a significant increase of the productivity (Rosabeth Moss Kanter 2000), aside from the constructive processes of the knowledge (new pedagogical concepts constructivista of Ormrod J.E. 2003 and Tim O´Reilly 2004).

source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 47-54.
summary	We consider the problem of automating the recoloring of designs whose “originals” are defined using color look-up tables. Given a digital image , we assume for each pixel of there exists an integer index such that . If is a color look-up table of size , we say image is colored by if each pixel is assigned color . Given a map from to itself, we recolor by assigning to each pixel the color . We are able to evolve the recoloring maps by representing them as -tuples. We automate their evolution by applying multi-objective optimization. Examples of recolorings of designs that were originally in color and originally in black and white are given. Keywords. Color look-up table, image recoloring, genetic algorithm, evolutionary multiobjective optimization.

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

title	Computer Visualizations in Planning
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	A wide range of visualizations have been developed and implemented as tools for urban simulations and visual impact assessment. These include: plans, diagrams, elevations, perspective sketches, renderings, modified photographs (photo renderings and photomontages), slide projections, scale models, movies, videotapes and computer graphics. In the last decade, graphical computer applications have proven to be an increasingly supportive tool in visualization and manipulation of graphical material. This study presents the state of the art of computer visualization in planning. More specifically, the use of web-based computerized visualizations for landscape visual simulation, with the aim to develop a system of visualization techniques as an aid to communicating planning and design scenarios for historically important landscapes and urban places, with particular attention to the city of Nablus in Palestine. This has led to the evaluation of possibilities and potentials of computer use in this field, and to the definition of the visual problems and challenges of the city of Nablus. This study will argue what extra one can draw from computerized visualizations, what is likely to be its impact on future planning and design research, and what this visualization experience really means for historical important locations as in Nablus. The study demonstrates that computerized visualizations can be a powerful tool in representing a cityscape in three-dimensions from different angels. Visualizations will allow better understanding of the components of the city, its landscapes, city features and the process of change. In this way it may provide new and better platforms for public participation in planning.

summary	During the event Cultural Market Days on 23 and 24 August 2003 at Noerrebro Park in Copenhagen, visitors could also enter the marketplace from their home via the Internet, as a digital 3D model had been constructed that showed the marketplace with all its information booths and activities. This virtual marketplace functioned as an extension of the urban space, allowing you to take part in the flow of information, activities and experiences that were offered in the marketplace. And this just by a click on the Internet address: http://www.e-kvarter.dk. Furthermore at certain times of the day you could chat with people from some of the many working groups of the urban regeneration project in Noerrebro. The digital 3D model is similar to the marketplace, but it creates its own universe in the green surroundings of Noerrebro Park. And now, when the Cultural Market Days are finished and the booths and people have gone, the Electronic Marketplace still remains on the Internet, with a potential for developing a new public space for information, dialogue and cooperation between the actors of the urban regeneration project. This paper presents the results of a 3-year research project, The Electronic Neighbourhood (2000-2004). Researchers have developed and tested a digital model of the urban area and other digital tools for supporting the dialogue and cooperation between professionals and citizens in an urban regeneration project in Copenhagen. The Danish Agency for Enterprise and Housing, the Ministry for Refugees, Immigration and Integration and Copenhagen Municipality have financed the research, which is planned to be published 2004. The results can also be followed on the Internet www.e-kvarter.dk.

source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 610-616
summary	The ultimate goal of the BIM concept is to create a complete digital model of the building to insure the generation of an accurate bill of material and cost estimate along with coordinated drawings and details. This goal might need the contribution of various disciplines to provide the needed level of information. The development of capable specialized systems to model specific building elements will definitely challenge the all-purpose architectural CAD. The specificity of these systems will enable fulfilling the needs than a general purpose architectural BIM system. This will lead the industry into creating either a powerful fully integrated BIM system that can handle all required information, or a referential BIM system that depends on passing the information to other programs (and other people) that are capable of handling specific tasks more efficiently.

summary	In this paper we present an approach to the differentiation and classification of two-dimensional design drawings. Our model is based on a qualitative encoding scheme and information theoretic measures. The model utilises information-theoretic tools to measure the similarity and complexity of a hierarchy of drawing descriptions. The descriptive and analytic power of the model is demonstrated by evaluating the different measures for a series of simple sketches and studying the time evolution of architectural plans produced by Frank Lloyd Wright.

title	Space is the Machine, with a Ghost Inside

summary	The purpose of this paper is to report efforts towards the construction of a model for urban spatial dynamics simulation, based on multi-agents and space. The underlying idea is to have urban space producers and consumers operating in a two-layer, two-circuit model. The first layer holds urban space and its successive transformations; a second layer contains agents related to space; the first circuit simulates space production, and a second one simulates space consumption. Relationship between layers is represented as objective spatial features that agents are submitted to (the machine) and subjective meanings agents attach to each spatial feature (the ghost). While space works always in the same way, meanings vary according to each agent’s background and context. Relationships between circuits are represented by means of a market game in which producers try to maximize their profits by gambling with their risks, whereas consumers try to foresee the spatial distribution of local externalities that maximizes their utilities and investments. Urban Spatial Features are captured through centrality and land use patterns; every single agent’s action leads to changes in both patterns. Producers’ profit is a function of built form location. Consumers’ local externalities are concerned basically with present and future services. The model iteration is twofold: first it generates and allocates a number of built forms within a previously determined spatial system (a cellular matrix, for example), and second it allocates users to built forms. Population of users have its social profile and growth rate externally determined. Built form allocation is decided on the basis of a combination of profitXrisk perspectives. Users’ locational choice is supported by accessibility to services and present/future neighbourhood profile. Built form allocation works as parameter for users’ locational assessment, whereas users’ choices are used as parameters for developers. The model tends to adjust itself, in terms of quantities and types of built forms to be erected, although through a market lag of some iterations. Allocations are always made through weighted draws, so that mutations (non deterministic allocations) do occur.
