title	Dislocations of the spatial experience: From earthwork to liquid architecture [Deslocamentos da experiência espacial: De earthwork a arquitetura líquida]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 423-427
summary	This article reflects about the contemporary notion of “spatial experience” that can be drawn by means of the emergence of the “expanded field” in arts (Rosalind Krauss, 1979). For a perspective view of this notion and for its problematization in the current time we pretend to stablish a counterpoint between two historic moments related to the expansion of the spatial field and its experience: the 1960´s, with the focus on the immanent space by artistic propositions, and nowadays, with the ocurrence of “fusional fields” of art-architecture-landscape-digital media. We adopt as strategy to construct the question, the approximation of two paradigmatic works for their respective epochs: the “earthwork” Spiral Jetty of Robert Smithson, constructed in 1970 in the Great Salt Lake (Utah, USA) and the ephemeral architecture of Blur Building of Elizabeth Diller and Ricardo Scofidio, constructed in 2002 in the Lake Neuchatel, for the Suiss Expo (Yverdon-les-Bains – Suiss).

title	A National Strategy for CAAD and IT-Implementation in the Construction Industry the Construction Industry
doi	https://doi.org/10.52842/conf.ecaade.1997.x.o8u
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	The objective of this paper is to present a strategy for implementation of CAD and IT in the construction and building management#1 industry in Sweden. The interest is in how to make the best use of the limited resources in a small country or region, cooperating internationally and at the same time avoiding to be totally dominated by the great international actors in the market of information technology. In Sweden representatives from the construction and building management industry have put forward a research and development program called: "IT-Bygg#2 2002 - Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry. The presented strategy is based on a seminar with some of the most experienced researchers, developers and practitioners of CAD in Sweden. The activities were recorded and annotated, analyzed and put together afterwards. The proposal in brief is that object oriented distributed CAD is to be used in the long perspective. It will need to be based on international standards such as STEP and it will take at least another 5 years to get established. Meanwhile something temporary has to be used. Pragmatically a "de facto standard" on formats has to be accepted and implemented. To support new users of IT all software in use in the country will be analyzed, described and published for a national platform for IT-communication within the construction industry. Finally the question is discussed "How can architect schools then contribute to IT being implemented within the housing sector at a regional or national level?" Some ideas are presented: Creating the good example, better support for the customer, sharing the holistic concept of the project with all actors, taking part in an integrated education process and international collaboration like AVOCAAD and ECAADE.

title	Implementation of IT and CAD - what can Architect schools do?

summary	In Sweden representatives from the Construction industry have put forward a research and development program called: "IT-Bygg 2002 -Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry. A seminar was held with some of the most experienced researchers, developers and practitioners of CAD in construction in Sweden. The activities were recorded and annotated, analysed and put together afterwards; then presented to the participants to agree on. Co-operation is the key to get to the goals - IT and CAD are just the means to improve it. Co-operation in a phase of implementation is enough problematic without the technical difficulties in using computer programs created by the computer industry primarily for commercial reasons. The suggestion is that cooperation between software companies within Sweden will make a greater market to share than the sum of all individual efforts. In the short term, 2 - 5 years, implementation of CAD and IT will demand a large amount of educational efforts from all actors in the construction process. In the process of today the architect is looked upon as a natural coordinator of the design phase. In the integrated process the architect's methods and knowledge are central and must be spread to other categories of actors - what a challenge! At least in Sweden the number of researchers and educators in CAAD is easily counted. How do we make the most of it?

title	Artificial Design and Planning Support: Interactive Plan Generation andCoordination in Distributed Decision-Making
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	In this paper we discuss some basic issues pertaining to artificial plan design as a paradigm for architectural design and urban planning support. We present a model for artificial design generation based on learning control methodologies. Plan design is seen as a search for "coordinated" solutions (changes) that satisfy distributed domain requirements and views expressed by human or artificial agents. Learning control is used as a method to search for solutions that direct partial descriptionsproduced by agents, to follow their dynamically defined targets -despite conflicting requirements. The model is simulated for land use and layout plan design, involving decisions for the location and physical configuration of a hypothetical housing and retail development.

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.

title	Design Decision Support through Translation between Multiple Representations of Spatial Data
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Urban planning and urban design involve collaboration of diverse participants with multiple agendas and multiple criteria. The participants typically use multiple representations of spatial data to derive inferences and insights about the planning problems, leading to a shared decision-making process. To support such multidisciplinary work, this paper proposes a new computational approach and technique for translation between multiple representations of spatial data. This approach is designed to supportdesign decision-making in the interrelated interests of design participants. Prototype implementation and evaluation are conducted to test and validate the proposals.

title	Implicaciones Arquitectónicas de La Naturaleza del Hacer en Ambientes Digitales [Architectonic Implications of the Nature of the Digital Atmosphere ]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 142-145
summary	Architectural Implications of the Nature of Making in Digital Environments There exists an a-priori relationship between the basic structural constrains of an environment and the types of construction that may evolve there. For instance, the inexorable laws of nature have caused architecture to develop as a physical, stable, containing and inert object. Hence there are good reasons to study how cyberspace with its different ontological foundations may define the architecture to be built there. This examination may be best accomplished by concentrating in how what is structurally unique to the cyber impacts architectural design This paper investigates the ontology of construction in cyberspace by analyzing ordinary digital laws that defy reality. The findings both challenge our traditional conceptions of architecture and guide us toward totally unprecedented design potentials. The goal is to begin building a fundamental theory of architectural space, design and construction applicable to cyberspace.

title	A Shape Compactness Measurement Indexing with Fuzzy Multicriteria Decision Making Approach
doi	https://doi.org/10.52842/conf.caadria.2002.093
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 093-100
summary	Compactness of a district or zone is determined by considering its appearance and the area of dispersal of the district (Altman, 1998) and it is used as a characteristic to describe shape (Shiode, 1998; Knight, 1997). However, existing compactness measurement used to assess district plans in redistricting applications are vague and imprecision although there are more than thirty over Euclidean or non-Euclidean measurement methods. Therefore, this paper presents an integrated shape compactness measurement indexing with a fuzzy multicriteria decision making approach (FMCDM) to enhance the measurement of shape compactness. An experiment is conducted in order to verify the practically of the proposed model to improve existing compactness measurement method.

source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 229-238
summary	In this paper, we present two user-centered systems aiming at making easier the modeling ofarchitectural and urban scenes by using two different but complementary approaches. The first oneMArINa, an image-based modeler, allows the user to reconstruct urban scenes from one or moregraphical documents. This method focuses more on reconstructing models and is more dedicated tothe production of 3D sketches. The second modeler, MArCo is a knowledge-based modelercontaining the know-from and know-how on classical architecture. It allows the user to modelclassical architectural scenes verifying automatically all the domain rules. Finally, we show howMArINa and MArCo can cooperate providing the user a tool combining efficiently their respectivecapabilities.

title	Relating to the ‘real’ Perceptions of Computer Aided and Physical Modelling
doi	https://doi.org/10.52842/conf.ecaade.2002.134
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 134-138
summary	Designing - giving form to new objects or environments - is largely a question of anticipating the workings of spatial and material environments, which can become ‘reality’ only by being built. Until ‘realized’ a design is essentially a figment of the designer’s imagination, although his or her ideas may be laid down and conveyed to others via specialized design media. In this way impressions of the design may be shared with clients, colleagues or other ‘actors’ in the design process. Such products of the designer’s imaging process can be relatively abstract or begin to approach - future - reality. Form & Media research can be ‘revealing’, stimulating insights concerning preferences, working processes and the effects of products of the designer’s imagination. In the past ten years we have gained considerable practical experience with both virtual and tangible (scale) models. We have compared different techniques in conference workshops, within educational settings and in our Form & Media research laboratory. The research projects ranged from the development of practical techniques and working methods to protocol analyses of designing architects. This contribution draws comparisons between different computer aided modelling techniques, with an indication of their perspectives, making use of the experience gained from various experiments in an educational context, and will highlight the potentials for different combinations of digital and physical modelling techniques.

title	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title	Making Sense of Presenting Design Ideas through Animated Form
doi	https://doi.org/10.52842/conf.ecaade.2002.560
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 560-563
summary	This paper describes both conventional and computational ways of expressing and exploring design concepts with the use of models. We explain the role and function of the model in the design process, and investigate the ways in which models become reflections and representations of architects’ design thinking. We compare and contrast the physical properties of conventional models with those of three-dimensional computer models, and the corresponding processes of model creation, model development, and model modification. The paper includes a brief overview of commonly used forms of computer representations often encountered in Computer Aided Design applications. Whatever the visual richness of computer models in virtual environments can be, we believe that, just as in the use of conventional two-dimensional architectural drawings, computational presentations of architectural design concepts have their own conventions of use. This paper addresses the need to more accurately understand these conventions of using computer models for the representation of architectural design concepts. Therefore, we will illustrate the more dynamic qualities of computer models, which have the potential to allow designers to escape from the restrictions and constraints of physical form. In particular, we demonstrate these qualities in the context of architectural presentations in the medium of computer animation. These new forms of expression of design thoughts and ideas go beyond mere model making, and move more towards scenemaking and storytelling. The latter represents new methods of expression within computational environments for architects and designers.

summary	Professional knowledge is a key component of the decision making process, as well as a major part of the thinking process. This research uses a strategy oriented by professional knowledge to assist the analysis of strategies in the design process, and to incite different design thinking under the operation models of media; through the basis of the design process, analyse the utilization of professional knowledge by designers in the design process and the different knowledge understanding methods under different media utilizations.

title	A Java3D Tool for Real-Time Collaboration in a Virtual Reality CAADEnvironment
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Today the development of network-based virtual communities and the use of avatars have brought a new level of complexity to the meaning of virtuality, providing the technology for remote presence and collaborative experiences. In this project the intention was to pursue this articulated vision of VR in order to assist the design profession during the early stages of the design process. The objective was to provide a tool that is capable of creating 3D shapes in a shared VR environment, thus allowing thedesign and its evolution to be shared. The use of the Java programming language was a natural choice for this project. Because of Java’s performance scalability and hardware independence the concept ofCAAD has been extended, making it possible to create a VR environment that can co-exist between high-end supercomputers and standard PCs. The project is currently being tested using PCs and an SGI system running a Reality Centre. The research reported in this paper describes the architecture and application of software that aims to increase the opportunity for collaboration within virtual worlds and enable effective and transparent information exchange.

title	Flexible and distributed coordination models for collaborative design
doi	https://doi.org/10.52842/conf.ecaade.2002.268
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 268-275
summary	Designers working in collaborative design situations, attempt to plan or anticipate their activities, such that their work progresses in an orderly manner, according to technical demands of their domain. Designers, and the organizations that employ them, often attempt to formally represent such plans using process representations, such critical path diagrams, or Petri nets. Such process articulation and formalization can have benefits for designers and organizations, such as standardization and improvement of work practices, and improved collaboration and coordination between design parties. In addition to plan making, designers also try to coordinate their actions with the actions of others on the design team. This coordination, which often takes place in real time, is a process that is necessarily social, interactive, and iterative. Here the formulation of suitable process representations is more difficult, due to the dynamic and complex nature of social interactions. How to represent and design such coordination processes, is a continuing research question in the process modeling community. It is possible there exists general coordination mechanisms that could be useful in a variety of domains. Possibilities for distributed methods of design process coordination are examined. A coordination method is proposed that involves the exchange of design process models, represented as Petri nets. Rather than concentrating on the specific content of these models - which is assumed to vary considerably between design domains - general coordinating mechanisms are proposed. One such mechanism involves the communication of social commitments to process models, in addition to communication of the content and authorship of these models.

title	Quantitatively Analysing Parametric Models
source	International Journal of Architectural Computing vol. 12 - no. 3, 307-320
summary	Architectural practices regularly work with parametric models, yet almost nothing is known about the general properties of these models. We do not know how large a typical model is, or how complicated, or even what the typical parametric model does. These knowledge gaps are the focus of this article, which documents the first large-scale quantitative parametric model survey. In this paper three key quantitative metrics - dimensionality, size, and cyclomatic complexity - are applied to a collection of 2002 parametric models created by 575 designers. The results show that parametric models generally exhibit a number of strong correlations, which reveal a practice of parametric modelling that has as much to do with the management of data as it does with the modelling of geometry. These findings demonstrate the utility of software engineering metrics in the description and analysis of parametric models.

summary	Over the last decade, advances in computer graphics plus the growing popularity of the Internet have incorporated the words reality and virtuality into our vocabulary, at the same time, making the distance between the words shorter. In this article, we discuss the two concepts - reality and virtuality - and analyze how this question has affected human communication, specially in the Web environment. This analysis will be used as a basis for research on the impact of “non-presence” in working relationships in a virtual environment, more specifically in the architecture and engineering areas where we find the Web being used as a communication tool for the development of collaborative design between groups involved with the design process of the built environment.

title	Conformance Checking by Capturing and Simulating Human Behaviour in the Built Environment
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	In order to model natural human behaviour, it is necessary to capture this behaviour. First, we will start out by modelling behaviour for specific situations, such as taking a seat in a theatre. To capture humanbehaviour, the following experiment is performed: Given a virtual environment, a sufficient number of subjects (real humans) are asked to execute a human task in this virtual environment (e.g. take a seat inthe theatre). Whenever the subject deviates from the shortest path, the system will ask for a clue why this is done. The hypothesis is that the combination of the motion paths and the clues for making/changing decisions will provide decision rules to make reliable predictions about human behaviour under the same conditions when using virtual persons. To test the hypothesis, we propose to use the university’s main conference and presentation hall as a test case. A 3D model and a motion pathgraph are constructed that enables a virtual person to find its way to a selected chair. The clues from the experiment are implemented as decision rules that determine a virtual person’s behaviour. Running thesimulation will result in the following data: Time per person to find a chair, Deviation from the shortest path, Distance covered per person to find a chair, Distribution of seated persons over time and Relocation of persons. To validate the test case, the process of people entering the hall and finding a chair is recorded on videotape. The walking behaviour of the people observed on the video is analysed and compared with the data from the simulation.

title	Towards a multi-agent model for visualizing simulated user behavior to support the assessment of design performance
source	Automation in Construction 11 (2) (2002) pp. 135-145
summary	We introduce the outline of a multi-agent model that can be used for visualizing simulated user behavior to support the assessment of design performance. We will consider various performance indicators of building environments, which are related to user reaction to design decisions. This system may serve as a media tool in the design process for a better understanding of what the design will look like, especially for those cases where design or planning decisions will affect the behavior of individuals. The system is based on cellular automata and multi-agent simulation technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. Each agent will be located in a simulated space, based on the cellular automata grid. Each iteration of the simulation is based on a parallel update of the agents conforming local rules. Agents positioned within an environment will need sensors to perceive their local neighborhood and some means with which to affect the environment. In this way, autonomous individuals and the interaction between them can be simulated by the system. As a result, designers can use the system to assess the likely consequences of their design decisions on user behavior. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior in architecture and urban planning.
