title	Modular Architectural Groupings from Escher Periodic Tessellations
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 205-219
summary	One of the more interesting design techniques developed by Dutch graphic artist M.C. Escher consists in covering the plane with tiles containing patterns that repeats periodically. Modularity within shape grouping is extensively used, expressed by natural figures from the living world, and also from worlds of fantasy. This paper attempts to use Eschers's ideas as a source of inspiration to obtain modular shapes to conform groups with architectural issues. The task is to satisfy design requirements and to get repeatable unitary shapes, whose geometric description is modularly manipulated within area as well as perimeter. This should be done by two procedures: 1. from the components to the whole (from the tiles to the tiling): once the designer has defined a modular constructive unit (solving a particular situation), it is possible to repeat the unit to generate modular groups, knowing that they will fit perfectly among them, without gaps nor overlaps. 2. from the whole to the components (from the tiling to the tiles): defining a tessellation with the particular rules that drives close to the architectural solution, and getting the necessary units from the tiling. There are multiple architectural themes on which this should be performed. School class-rooms, habitation buildings, shopping center sites, hotel rooms, are examples of this statement. Analyzing procedures followed by the artist, particularly those using figures that tessellate the plane periodically, we'll be able to generate tiles with architectural shape by the same way, applying different symmetry rules. Once the rules to generate shapes of tiles are known, we work within area and perimeter to satisfy modularity requirements and to convert the tiling as a geometric precise support for the insertion of architectural objects that follow predetermined dimensional patterns. In order to illustrate these ideas an example of grouping repeatable habitation units is presented.

title	Formal Alternatives Through Ludic Process Applied to Tessellation
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 101-108
summary	The digital graphic systems development is evident during the alternative generation process, especially when the component objects are linked to a geometric base by modulation. In this sense, the tiling modular characteristics are used as geometric support which modulation or internal divisions contain material forms (objects in 3D) immaterial forms (spaces in 3D). That is to say that each tiling module can be projected or not in 3D. The way to do this consists of applying it not only as two-dimensional support but also as operational structure by means of operations of pure translation, in 3D. It is applied to architectural themes which systemic parts or components sectors admit repetitions of units (dwelling buildings, schools, offices, hotels, etc.) in plan floor levels and in elevation as well. When programmatic and morphological requirements are solved groups are organized conforming systems in two or three dimensions. In the alternative generation stage it is tried to avoid conditioning and restrictions developing a ludic process of "piling up tiles" simple concepts stimulating creativity for the production of innovating architectonic forms. Creative ideas can arise from the game playing with 3D forms. This paper attempts to show a manner to generate unusual architectural forms that, otherwise, within a traditional design process might not be found. Some architectural examples developed with this ludic procedure are presented.

title	Las Teselas de Penrose como generadoras de Agrupamientos de Formas Arquitectónicas Regulares (The "Teselas de Penrose" as Generators of Groups of Regular Architectural Forms)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 161-164
summary	Considering plane tessellation as a creative trigger that contributes to modular form design, a procedure to group 2D shapes and architectural 3D forms is developed. The particular case studied in this article is about Penrose tilings, which tessellate no-periodically, admitting a covering of the plane without using a constant distance repetition pattern. Procedures and rules for geometric generation and fractalization are analyzed. A technique to generate aperiodic tilings is proposed, so they will be used as a geometric precise support for the insertion of architectural objects that follow predetermined dimensional patterns, looking for constructive standardization without restricting diversity of cases. Using digital techniques, linear and central structures of groupings are analyzed. Both typologies are exemplified in various abstraction levels.

title	Creativity and Modularity in Architecture
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 169-179
summary	The Modern Movement in Architecture put forward industrialization, mass production and standardization among its most important banners. At the end of the century those principles are partially applied. However, the overwhelming growing of exchanges and the purchase of artifacts coming from all over the world to be assembled in order to create new artifacts, determines that in the short span, a world wide standardization becomes unavoidable. Designers should be aware about this imminent issue. Working with standard objects means modular thinking. If modules are conceived as sort of constraining entities framing the mind, creative thinking is facing a gloomy prospect. Creativity and freedom seem to be jeopardized by ready made objects. In fact, from the beginning of design as a form- giving activity it exists a dialectic between creativity and feasibility. It is not surprising since designing is essentially the transformation of ideas into real world objects. Nonetheless, the increasing standardization and the indispensable use of computers are exasperating that dialectics. In this paper is argued that if the characteristics of modular procedures are used in the early stage of the design process to prompt the form for further adjustment, creative thinking is released from excessive awareness about dimensional constraints. The first part of the paper is devoted to the description of the contextural trends that make modular thinking relevant. In the second part some propositions about the use of computer systems to generate "modular freedom" are exposed together with examples illustrating the proposed process.

title	On multi body systems simulation in product design
source	KTH Stockholm
summary	The aim of this thesis is to provide a basis for efficient modelling and software use in simulation driven product development. The capabilities of modern commercial computer software for design are analysed experimentally and qualitatively. An integrated simulation model for design of mechanical systems, based on four different "simulation views" is proposed: An integrated CAE (Computer Aided Engineering) model using Solid Geometry (CAD), Finite Element Modelling (FEM), Multi Body Systems Modelling (MBS) and Dynamic System Simulation utilising Block System Modelling tools is presented. A theoretical design process model for simulation driven design based on the theory of product chromosome is introduced. This thesis comprises a summary and six papers. Paper A presents the general framework and a distributed model for simulation based on CAD, FEM, MBS and Block Systems modelling. Paper B outlines a framework to integrate all these models into MBS simulation for performance prediction and optimisation of mechanical systems, using a modular approach. This methodology has been applied to design of industrial robots of parallel robot type. During the development process, from concept design to detail design, models have been refined from kinematic to dynamic and to elastodynamic models, finally including joint backlash. A method for analysing the kinematic Jacobian by using MBS simulation is presented. Motor torque requirements are studied by varying major robot geometry parameters, in dimensionless form for generality. The robot TCP (Tool Center Point) path in time space, predicted from elastodynamic model simulations, has been transformed to the frequency space by Fourier analysis. By comparison of this result with linear (modal) eigen frequency analysis from the elastodynamic MBS model, internal model validation is obtained. Paper C presents a study of joint backlash. An impact model for joint clearance, utilised in paper B, has been developed and compared to a simplified spring-damper model. The impact model was found to predict contact loss over a wider range of rotational speed than the spring-damper model. Increased joint bearing stiffness was found to widen the speed region of chaotic behaviour, due to loss of contact, while increased damping will reduce the chaotic range. The impact model was found to have stable under- and overcritical speed ranges, around the loss of contact region. The undercritical limit depends on the gravitational load on the clearance joint. Papers D and E give examples of the distributed simulation model approach proposed in paper A. Paper D presents simulation and optimisation of linear servo drives for a 3-axis gantry robot, using block systems modelling. The specified kinematic behaviour is simulated with multi body modelling, while drive systems and control system are modelled using a block system model for each drive. The block system model has been used for optimisation of the transmission and motor selection. Paper E presents an approach for re-using CAD geometry for multi body modelling of a rock drilling rig boom. Paper F presents synthesis methods for mechanical systems. Joint and part number synthesis is performed using the Grübler and Euler equations. The synthesis is continued by applying the theory of generative grammar, from which the grammatical rules of planar mechanisms have been formulated. An example of topological synthesis of mechanisms utilising this grammar is presented. Finally, dimensional synthesis of the mechanism is carried out by utilising non-linear programming with addition of a penalty function to avoid singularities.

summary	The study of a cyberuniversity derives from an analogy between real urban space and its virtual "substitution". It represents an attempt to balance some views, which seems to be contrary, exclusive, but they are just parts of the same wholeness. Especially the notion of a cyber society is lately considered such an exaggeration, that it is possible to forget the meaning of a real life experience and interactions, which are already threatened. One should contribute to the awarness that is used in such a comparison, it is "just" an analogy, not a real similarity. At the same time it is possible to point out some limitations of a cyberspace and indicate a more realistic view of the meaning of cyber communities. Awarness of the development processes could help to find a balance between reality and virtuality, using cyberfacilities not to destroy us (our identity) but to improve the quality of our (real) life.

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Virtual Reality in the Design Studio: The Eindhoven Perspective

summary	Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

title	CAAD - Integrated with the First Steps into Architecture

summary	How and when should CAAD be introduced in the curriculum of the School of Architecture? This paper begins with some arguments for starting CAAD education at the very beginning. At the School of Architecture in Lund teachers in the first year courses have tried to integrate CAAD with the introduction to architectural concepts and techniques. Traditionally the first year is divided by several subjects running courses separatly without any contact for coordination. From the academic year 96/97 the teachers of Aplied aestetics, Building Science, Architectural design and CAAD have decided to colaborate as much as possible to make the role of our different fields as clear as possible to the students. Therefore integrating CAAD was a natural step in the academic year 98/99. The computer techniques were taught one step in advance so that the students can practise their understanding of the programs in their tasks in the other subjects. The results were surprisingly good! The students have quickly learned to mix the manual and computer techniques to make expressive and interesting visual presentations of their ideas. Some students with antipaty to computers have overcome this handicap. Some interesting observations are discussed.

title	Visualisation of Design Using Animation for Virtual Prototyping

summary	Although recent technology in time-based representation has vastly improved, animation in virtual prototype design field remains the same. Some designers invest a huge amount of money in the latest visualisation and multimedia technology and yet may create even worse animation. They often cramp sequences resulting in many viewers failing to interpret the design positively as they miss a lot of vital information that explains the design. This paper basically reports the importance of film-making understanding for producing good virtual prototype animation. It will be based on a part of a research project on the use of time-based media in architectural practices. It also includes an empirical analysis of several architectural-based documentary films (including an interview with the film director) and past and present computer animation. This paper then concludes with recommendations of good techniques for making animated visualisation relative to the stage at which the animation is produced for better design decision.

summary	conditions a time-spatial discontinuity in the urban grid, ancient walls casually discovered in a substrate of the contemporary town needs a surplus of information to be understood and interfaced with their current condition. diagrams diverse chronological stages of the urban evolution are mapped on the area, in order to read the historical stratifications as a multiplicity of signs; this abstract approach leads to consider the roman space as guided by metrics, a system of measure superimposed on the landscape, vs. medioeval spatial continuity, where more fluid relations between the same urban elements create a completely different pattern.assemblage (time sections) a surface, automatically displaced from the medioeval diagram, moves along the z axis, the historical stratification direction, intersecting in various, unpredictable, manners a series of paths; these paths start as parallels, allowing an undifferentiated access to the area, and mutate along their developing direction, intertweening and blending each other; linear openings are cut on the surface, virtually connecting the two levels by light, following the roman grid in rhythm and measure. Projected on the lateral wall, the cadence of the vertical and horizontal elements becomes a temporal diagram of the design process.movement time takes part into the process through two kinds of movement: the first one, freezed when reaches the best results, in terms of complexity, is given by the surface intersecting the tubular paths; the second one is represented by multiple routes walking on which the project can be experienced (in absence of any objective, fixed, point of view, movement becomes the only way to understand relations). Thresholds between typical architectural categories (such as inside-outside, object-landscape etc.) are blurred in favour of a more supple condition, another kind of continuity (re)appears, as a new media, between the different historical layers of the city.

title	CAD Interfaces to the ARROW Manufactured Product Server
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary	The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

doi	https://doi.org/10.52842/conf.ecaade.1999.094
summary	This paper describes the three generations of CAD systems. The first generation of (primarily analytical) computer programmes really aided designing. These programmes were the tools for finding a functional solution in different areas of designing, from flat plans to the space organisation of a hospital. One of the shortcomings of these programmes was the lack of graphic interface. With time, however, this kind of interface was developed. As a result of this second generation of CAD systems the computer was transformed into a drafting machine and CAD meant Computer Aided Drafting. The main thesis of this consideration is that only now we have the chance to return to the idea of Computer Aided Design. One of the examples of these trends is the AVOCAAD programme in which Added Value of CAAD is analysed. The development of the third generation of CAD systems will be possible in the near future. Aiding the process of designing will demand the elaboration of new methods of using the computer at the early stages of this process. The computer should be used not for generating variants of functional solutions only but for also for the creation of 3D forms by 3D sketching. For this, the computer should be transformed from a tool into a medium; only then will designing become true Designing in Cyber Space.

title	Facilitating Conceptual Change: Computers, Cognitive Processes and Architecture
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 275-279
summary	Computers have gained universal acceptance as tools that designers use. However, computers are often not used to advance the design process but just to make drawings. Many architectural schools still focus on a production orientation which puts the highest value on information management, precise representations and drafting enhancements. Mostly, computer education is limited with button pushing and training manuals. It is the contention of the author that students in Design Studio courses can benefit greatly from computer based educational pedagogy designed to provide them with experiences they currently do not possess. In particular, little time in the computer courses (outside lectures) is spent applying concepts and features of digital tools in design studio environment. In architecture, computers cannot be simply defined as a presentation and production tools. As a cognitive tool, computers provide designers with intelligible and effective representational tools of thought and communication, changes the syntactic structure of design. Consequently, the conceptual structure of computers impacts the conceptual structure of the design project, fosters the analytical processes and facilitates conceptual changes. This paper describes the use of computers in a first year architectural design studio. It attempts to address the importance of developing a design process that is redefined by the use of computing, integrating concept and perception. Furthermore, it describes the theoretical foundations and the underlying cognitive processes that contribute designers' conceptual development.

source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, 398 p.
summary	This is the eight CAADfutures Conference. Each of these bi-annual conferences identifies the state of the art in computer application in architecture. Together, the series provides a good record of the evolving state of research in this area over the last fourteen years. Early conferences, for example, addressed project work, either for real construction or done in academic studios, that approached the teaching or use of CAD tools in innovative ways. By the early 1990s, such project-based examples of CAD use disappeared from the conferences, as this area was no longer considered a research contribution. Computer-based design has become a basic way of doing business. This conference is marked by a similar evolutionary change. More papers were submitted about Web- based applications than about any other area. Rather than having multiple sessions on Web-based applications and communications, we instead came to the conclusion that the Web now is an integral part of digital computing, as are CAD applications. Using the conference as a sample, Web-based projects have been integrated into most research areas. This does not mean that the application of the Web is not a research area, but rather that the Web itself is an integral tool in almost all areas of CAAD research.

title	Posicionamiento de Volúmenes Arquitectónicos Mediante Algoritmos Evolucionistas (Positioning of Architectural Volumes by Means of Evolutionist Algorithms)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 176-181
summary	Configurational studies involve the groups of elements fulfilling restrictions defined by the designer in Architectural design. According to its necessities and intentions, the planner distributes the components of the group in a certain tridimensional way, establishing a composition. This operative procedure implies a classification system according to typologies that respond to a bigger system, and this in turn to another, until the whole is obtained. From the beginning the pattern should satisfy form restrictions, as well as dimensional and positional restrictions for each part that conforms the whole. Functional requirements are attended for each object satisfying relationships of connectivity and adjacency among them. In this work the parts are restricted by their relative position to a central element. Evolutionary Algorithms (EA) are used to solve this type of problem. Using evolutionary metaphors they originate concepts such as "genes", "chromosomes", "mutation", "crosses” and " population " (among other), which come closer to one of the solutions looked for by the designer, under combinatory stochastic methods. The most appropriate use of EA corresponds to problems of complexity NP-completeness (for example, problems of generation of cases of composition), allowing an efficient although not exhaustive analysis. Applying this technique to the generation of architectural volumes, some obtained results are exemplified.

summary	This work is part of a long term research programme (Brown and Horton, 1992; Brown and Nahab, 1996; Bassanino, 1999) in which tests and studies have been carried out on various groups of people to investigate their reaction to, and interpretation of different forms of architectural representation. In the work described here a range of architectural schemes were presented using particular representational techniques and media. An experiment was then undertaken on two different groups; architects and lay people. They were presented with a number of schemes displayed using the various techniques and media. The responses are summarised and some comments are made on the effect of computers on perceiving architecture and on communicating architectural ideas arising from an analysis of the responses.

summary	The program is organized into four parts. Each is very much connected, both logically and methodologically, so that the unit as a whole consists of a content and method of access that are not divided up. This method is not in a chronological order that simply goes in one direction, rather it allows the user to "refer back", in real time and in different directions. For the simple purpose of explanation, the sections of the program are listed as follows: (-) "Basic information" concerns the basics of bioclimatic and timber architecture. Without this knowledge, the other two sections would be difficult to understand; (-) "Actual buildings throughout the world"; give examples of architectural quality; they concretize the basics of bioclimatic and timber architecture; (-) "Students' Masters Theses", that follow on from the basic information and the learning experience "in the field", and guided by the lecturer, have a critical approach to actual buildings throughout the world. (-) A multimedia data-sheet organized to ensure a clear and straightforward presentation of information about the construction products. It relies on a tab-based navigation interface that gives users access to eight different stacked windows.

title	Evolutionary Design by Computers Morgan Kaufmann
source	San Francisco, CA
summary	Computers can only do what we tell them to do. They are our blind, unconscious digital slaves, bound to us by the unbreakable chains of our programs. These programs instruct computers what to do, when to do it, and how it should be done. But what happens when we loosen these chains? What happens when we tell a computer to use a process that we do not fully understand, in order to achieve something we do not fully understand? What happens when we tell a computer to evolve designs? As this book will show, what happens is that the computer gains almost human-like qualities of autonomy, innovative flair, and even creativity. These 'skills'which evolution so mysteriously endows upon our computers open up a whole new way of using computers in design. Today our former 'glorified typewriters' or 'overcomplicated drawing boards' can do everything from generating new ideas and concepts in design, to improving the performance of designs well beyond the abilities of even the most skilled human designer. Evolving designs on computers now enables us to employ computers in every stage of the design process. This is no longer computer aided design - this is becoming computer design. The pages of this book testify to the ability of today's evolutionary computer techniques in design. Flick through them and you will see designs of satellite booms, load cells, flywheels, computer networks, artistic images, sculptures, virtual creatures, house and hospital architectural plans, bridges, cranes, analogue circuits and even coffee tables. Out of all of the designs in the world, the collection you see in this book have a unique history: they were all evolved by computer, not designed by humans.

title	Integrating GIS and Electronic Networks In Urban Design and Planning
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 722-728

summary	In 1998 I undertook an inquiry into the use of information technology in Urban Design and Planning in Danish municipalities and among planning consultants. The aim was to find out who was working with the IT and for what purposes it was used. In education there seems to be barriers to a full integration of the new media, and I wanted to find out if that was also the case in the practise of architects and planners. Surprisingly I discovered that there was a computer on almost every desk, - but there were big differences in the use of the technology. The investigation described here is based on interviews with planners in selected municipalities and with urban planning consultants, and the results have been summarised in a publication.
