title Toward a procedure of computer simulation in the restoration of historical architecture
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 the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title Networked VR System: Kitchen Layout Design for Customers
source Proceedings of the second symposium on Virtual reality modeling language, Monterey, California, United States, pp.93-100
summary In this paper, we present our Virtual Reality (VR) technology application, a networked VR-supported design system of a kitchen layout. This networked VR system was developed on personal computers to allow customers to design at home. With the VR system, customers can have a pseudo-experience of their “virtual kitchen”, modify the design of the kitchen, and make decisions by being provided with a good idea of their potential purchase. The VR system will also play an important role in user interface in the House Design Advisory System. This system, which we are currently developing, will give advice on house design, as well as on kitchen layout design, according tothe customers’ diversified lifestyles.

title Possible Futures in Computer Art Generation
source International Conference on Generative Art
summary Years of trying to create an "Image Idea Generator" program have convinced me that the perfect solution would be to have an artificial artistic person, a design slave. This paper describes how I came to that conclusion, realistic alternatives, and briefly, how it could possibly happen. 1. The history of Repligator and Gliftic 1.1 Repligator In 1996 I had the idea of creating an “image idea generator”. I wanted something which would create images out of nothing, but guided by the user. The biggest conceptual problem I had was “out of nothing”. What does that mean? So I put aside that problem and forced the user to give the program a starting image. This program eventually turned into Repligator, commercially described as an “easy to use graphical effects program”, but actually, to my mind, an Image Idea Generator. The first release came out in October 1997. In December 1998 I described Repligator V4 [1] and how I thought it could be developed away from simply being an effects program. In July 1999 Repligator V4 won the Shareware Industry Awards Foundation prize for "Best Graphics Program of 1999". Prize winners are never told why they won, but I am sure that it was because of two things: 1) Easy of use 2) Ease of experimentation "Ease of experimentation" means that Repligator does in fact come up with new graphics ideas. Once you have input your original image you can generate new versions of that image simply by pushing a single key. Repligator is currently at version 6, but, apart from adding many new effects and a few new features, is basically the same program as version 4. Following on from the ideas in [1] I started to develop Gliftic, which is closer to my original thoughts of an image idea generator which "starts from nothing". The Gliftic model of images was that they are composed of three components: 1. Layout or form, for example the outline of a mandala is a form. 2. Color scheme, for example colors selected from autumn leaves from an oak tree. 3. Interpretation, for example Van Gogh would paint a mandala with oak tree colors in a different way to Andy Warhol. There is a Van Gogh interpretation and an Andy Warhol interpretation. Further I wanted to be able to genetically breed images, for example crossing two layouts to produce a child layout. And the same with interpretations and color schemes. If I could achieve this then the program would be very powerful. 1.2 Getting to Gliftic Programming has an amazing way of crystalising ideas. If you want to put an idea into practice via a computer program you really have to understand the idea not only globally, but just as importantly, in detail. You have to make hard design decisions, there can be no vagueness, and so implementing what I had decribed above turned out to be a considerable challenge. I soon found out that the hardest thing to do would be the breeding of forms. What are the "genes" of a form? What are the genes of a circle, say, and how do they compare to the genes of the outline of the UK? I wanted the genotype representation (inside the computer program's data) to be directly linked to the phenotype representation (on the computer screen). This seemed to be the best way of making sure that bred-forms would bare some visual relationship to their parents. I also wanted symmetry to be preserved. For example if two symmetrical objects were bred then their children should be symmetrical. I decided to represent shapes as simply closed polygonal shapes, and the "genes" of these shapes were simply the list of points defining the polygon. Thus a circle would have to be represented by a regular polygon of, say, 100 sides. The outline of the UK could easily be represented as a list of points every 10 Kilometers along the coast line. Now for the important question: what do you get when you cross a circle with the outline of the UK? I tried various ways of combining the "genes" (i.e. coordinates) of the shapes, but none of them really ended up producing interesting shapes. And of the methods I used, many of them, applied over several "generations" simply resulted in amorphous blobs, with no distinct family characteristics. Or rather maybe I should say that no single method of breeding shapes gave decent results for all types of images. Figure 1 shows an example of breeding a mandala with 6 regular polygons: Figure 1 Mandala bred with array of regular polygons I did not try out all my ideas, and maybe in the future I will return to the problem, but it was clear to me that it is a non-trivial problem. And if the breeding of shapes is a non-trivial problem, then what about the breeding of interpretations? I abandoned the genetic (breeding) model of generating designs but retained the idea of the three components (form, color scheme, interpretation). 1.3 Gliftic today Gliftic Version 1.0 was released in May 2000. It allows the user to change a form, a color scheme and an interpretation. The user can experiment with combining different components together and can thus home in on an personally pleasing image. Just as in Repligator, pushing the F7 key make the program choose all the options. Unlike Repligator however the user can also easily experiment with the form (only) by pushing F4, the color scheme (only) by pushing F5 and the interpretation (only) by pushing F6. Figures 2, 3 and 4 show some example images created by Gliftic. Figure 2 Mandala interpreted with arabesques   Figure 3 Trellis interpreted with "graphic ivy"   Figure 4 Regular dots interpreted as "sparks" 1.4 Forms in Gliftic V1 Forms are simply collections of graphics primitives (points, lines, ellipses and polygons). The program generates these collections according to the user's instructions. Currently the forms are: Mandala, Regular Polygon, Random Dots, Random Sticks, Random Shapes, Grid Of Polygons, Trellis, Flying Leap, Sticks And Waves, Spoked Wheel, Biological Growth, Chequer Squares, Regular Dots, Single Line, Paisley, Random Circles, Chevrons. 1.5 Color Schemes in Gliftic V1 When combining a form with an interpretation (described later) the program needs to know what colors it can use. The range of colors is called a color scheme. Gliftic has three color scheme types: 1. Random colors: Colors for the various parts of the image are chosen purely at random. 2. Hue Saturation Value (HSV) colors: The user can choose the main hue (e.g. red or yellow), the saturation (purity) of the color scheme and the value (brightness/darkness) . The user also has to choose how much variation is allowed in the color scheme. A wide variation allows the various colors of the final image to depart a long way from the HSV settings. A smaller variation results in the final image using almost a single color. 3. Colors chosen from an image: The user can choose an image (for example a JPG file of a famous painting, or a digital photograph he took while on holiday in Greece) and Gliftic will select colors from that image. Only colors from the selected image will appear in the output image. 1.6 Interpretations in Gliftic V1 Interpretation in Gliftic is best decribed with a few examples. A pure geometric line could be interpreted as: 1) the branch of a tree 2) a long thin arabesque 3) a sequence of disks 4) a chain, 5) a row of diamonds. An pure geometric ellipse could be interpreted as 1) a lake, 2) a planet, 3) an eye. Gliftic V1 has the following interpretations: Standard, Circles, Flying Leap, Graphic Ivy, Diamond Bar, Sparkz, Ess Disk, Ribbons, George Haite, Arabesque, ZigZag. 1.7 Applications of Gliftic Currently Gliftic is mostly used for creating WEB graphics, often backgrounds as it has an option to enable "tiling" of the generated images. There is also a possibility that it will be used in the custom textile business sometime within the next year or two. The real application of Gliftic is that of generating new graphics ideas, and I suspect that, like Repligator, many users will only understand this later. 2. The future of Gliftic, 3 possibilties Completing Gliftic V1 gave me the experience to understand what problems and opportunities there will be in future development of the program. Here I divide my many ideas into three oversimplified possibilities, and the real result may be a mix of two or all three of them. 2.1 Continue the current development "linearly" Gliftic could grow simply by the addition of more forms and interpretations. In fact I am sure that initially it will grow like this. However this limits the possibilities to what is inside the program itself. These limits can be mitigated by allowing the user to add forms (as vector files). The user can already add color schemes (as images). The biggest problem with leaving the program in its current state is that there is no easy way to add interpretations. 2.2 Allow the artist to program Gliftic It would be interesting to add a language to Gliftic which allows the user to program his own form generators and interpreters. In this way Gliftic becomes a "platform" for the development of dynamic graphics styles by the artist. The advantage of not having to deal with the complexities of Windows programming could attract the more adventurous artists and designers. The choice of programming language of course needs to take into account the fact that the "programmer" is probably not be an expert computer scientist. I have seen how LISP (an not exactly easy artificial intelligence language) has become very popular among non programming users of AutoCAD. If, to complete a job which you do manually and repeatedly, you can write a LISP macro of only 5 lines, then you may be tempted to learn enough LISP to write those 5 lines. Imagine also the ability to publish (and/or sell) "style generators". An artist could develop a particular interpretation function, it creates images of a given character which others find appealing. The interpretation (which runs inside Gliftic as a routine) could be offered to interior designers (for example) to unify carpets, wallpaper, furniture coverings for single projects. As Adrian Ward [3] says on his WEB site: "Programming is no less an artform than painting is a technical process." Learning a computer language to create a single image is overkill and impractical. Learning a computer language to create your own artistic style which generates an infinite series of images in that style may well be attractive. 2.3 Add an artificial conciousness to Gliftic This is a wild science fiction idea which comes into my head regularly. Gliftic manages to surprise the users with the images it makes, but, currently, is limited by what gets programmed into it or by pure chance. How about adding a real artifical conciousness to the program? Creating an intelligent artificial designer? According to Igor Aleksander [1] conciousness is required for programs (computers) to really become usefully intelligent. Aleksander thinks that "the line has been drawn under the philosophical discussion of conciousness, and the way is open to sound scientific investigation". Without going into the details, and with great over-simplification, there are roughly two sorts of artificial intelligence: 1) Programmed intelligence, where, to all intents and purposes, the programmer is the "intelligence". The program may perform well (but often, in practice, doesn't) and any learning which is done is simply statistical and pre-programmed. There is no way that this type of program could become concious. 2) Neural network intelligence, where the programs are based roughly on a simple model of the brain, and the network learns how to do specific tasks. It is this sort of program which, according to Aleksander, could, in the future, become concious, and thus usefully intelligent. What could the advantages of an artificial artist be? 1) There would be no need for programming. Presumbably the human artist would dialog with the artificial artist, directing its development. 2) The artificial artist could be used as an apprentice, doing the "drudge" work of art, which needs intelligence, but is, anyway, monotonous for the human artist. 3) The human artist imagines "concepts", the artificial artist makes them concrete. 4) An concious artificial artist may come up with ideas of its own. Is this science fiction? Arthur C. Clarke's 1st Law: "If a famous scientist says that something can be done, then he is in all probability correct. If a famous scientist says that something cannot be done, then he is in all probability wrong". Arthur C Clarke's 2nd Law: "Only by trying to go beyond the current limits can you find out what the real limits are." One of Bertrand Russell's 10 commandments: "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric" 3. References 1. "From Ramon Llull to Image Idea Generation".

summary Since 1997, the Institute for Industrial Building Production (ifib) has been carrying out upper level design studios under the framework of the Netzentwurf or Net-Studio. The Netzentwurf is categorized as a virtual design studio in that the environment for presentation, criticism and communication is web based. This allows lessons learned from research into Computer Supported Cooperative Work (CSCW) to be adapted to the special conditions indigenous to the architectural design studio. Indeed, an aim of the Netzentwurf is the creation and evolution of a design studio planing platform. In the Winter semester 1999-2000, ifib again carried out two Netzentwurf studios. involving approximately 30 students from the Faculty of Architecture, University of Karlsruhe. The projects differed from previous net studios in that both studios encompassed an inter-university character in addition to the established framework of the Netzentwurf. The first project, the re-use of Fort Kleber in Wolfisheim by Strasbourg, was carried out as part of the Virtual Upperrhine University of Architecture (VuuA) involving over 140 students from various disciplines in six institutions from five universities in France, Switzerland and Germany. The second project, entitled "Future, Inc.", involved the design of an office building for a scenario 20 years hence. This project was carried out in parallel with the Technical University Cottbus using the same methodology and program for two separate building sites.

summary The Bartlett School of Graduate Studies, University College London (UCL), set up the first MSc in Virtual Environments in the UK in 1995. The course aims to synthesise and build on research work undertaken in the arts, architecture, computing and biological sciences in exploring the realms of the creation of digital and virtual immersive spaces. The MSc is concerned primarily with equipping students from design backgrounds with the skills, techniques and theories necessary in the production of virtual environments. The course examines both virtual worlds as prototypes for real urban or built form and, over the last few years, has also developed an increasing interest in the the practice of architecture in purely virtual contexts. The MSc course is embedded in the UK government sponsored Virtual Reality Centre for the Built Environment which is hosted by the Bartlett School of Architecture. This centre involves the UCL departments of architecture, computer science and geography and includes industrial partners from a number of areas concerned with the built environment including architectural practice, surveying and estate management as well as some software companies and the telecoms industry. The first cohort of students graduated in 1997 and predominantly found work in companies working in the new market area of digital media. This paper aims to outline the nature of the course as it stands, examines the new and ever increasing market for designers within digital media and proposes possible future directions for the course.

title The visual harmony between new and old materials in the restoration of historical architecture: A study of computer simulation
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 the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

summary This paper describes a system designed to help architecture students in designing three-dimensional objects in a collaborative way. When implementing this system, VRML (Virtual Reality Modeling Language), Java and Javascript are used. This system uses the World Wide Web, which is getting more and more popular in recent years, as the media to transfer information all over the world.

The system allows many users to view three-dimensional objects, change attributes of the objects, discuss and design at the same time. These users can be located in different parts of the world. Each only needs a computer that is connected to the Internet and a web browser that can display VRML objects to use the system. The computer can be any hardware platform running any Operating System.

The objective of this project is to develop a system that can run on any computer hardware and software platform. Without any limitation on hardware and software platform, people from different parts of the world can work collaboratively to design architectural objects.

title Integrating Design Tools within a Human Collaborative Working
source The Int. Journal of Construction IT 5(2), pp. 47-73
summary This paper stresses the importance of establishing a collaborative working context as the basis for design integration. Within a virtual studio environment framework, a hybrid architecture for design tool integration is presented. Each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A global product model, which is augmented with meta-data description, is employed to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. Collaboration-aware information is modelled and structured through the meta-data model and a tool model. Based on this, mechanisms for tool service coodination in varying modes are developed. It is then illustrated, through an implemented prototype system, how the integrated design tools might be used in human design work.

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.

title Design and Analysis
source New York: Van Nostrand Reinhold
summary Design and Analysis by Bernard Leupen, Christoph Grafe, Nicola Körnig, Marc Lampe, and Peter de Zeeuw Design and Analysis is an insightful, interdisciplinary exploration of the diversity of analytic methods used by architects, designers, urban planners, and landscape architects to understand the structure and principles of the built environment. Developed by a team headed by Bernard Leupen at Delft University of Technology, The Netherlands, Design and Analysis defies borders of history, geography, and discipline, tracing the evolution of design principles from ancient Greece to the 20th century. "Only methodical analysis gives us an insight into the design process," states architect Bernard Tschumi. Using historical examples from architecture, urban design, and landscape architecture, Design and Analysis defines an ordered system that enables the design student or professional to identify the factors that influence designers' decisions, and shows how to relate them to the finished project. Design and Analysis is organized into six chapters that correspond to these factors: order and composition, functionality, structure, typology, context, and analytical techniques. The authors introduce the analytical drawing as a time-tested means to obtaining insight into the design process. Over 100 line drawings are featured in all. Using contemporary architectural examples to teach ancient design principles, Design and Analysis is more than just an introduction to analytical methods. The authors give an outline of space design as a whole, from individual buildings to urban and landscape ensembles. Though primarily intended for design students to help them appreciate many of the issues that they will face as professionals, Design and Analysis's broad, easy-to-read approach makes it an invaluable handbook for designers of all disciplines.

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.

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 Developing a new endoscopy laboratory with digital tools.
source Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary Tampere School of Architecture had to leave its old down-town building and move to the TU Tampere university campus in Hervanta, 10 km away. In this process, the 20 years old endoscopic system "The Urban Simulator" was one of the victims. Old mechanical parts and especially the original home-built microcomputer system were too old to compete with modern computer-aided methods. A new endoscopical system is now under construction, using all of the 20-year experience, new technical components and computers for camera control and picture processing. Real-material modelling is used together with computer-aided planning and visualization methods taking the best from both sides.

summary The term ‚Intelligenz Vuilding‘ is not any longer a mere slogan used by smart salesmen of commercial and / or office buildings. During recent years it has come to describe a broad engineering concept for building design, construcions and operation, the realization of which challenges architects and engineers involved in the various aspects of building industry. The concept empasizes a multidisciplinary effort to integrate and potimize the building strctures, systems , services and management in order to create a productive and responsive environment for teh building occupant, in a cost-effective manner.

title From 2D Base Map To 3D City Model
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title RealSpace in QuickTimes: architecture and digitization
source Rotterdam: Nai Publishers
summary Time and space, drastically compressed by the computer, have become interchangeable. Time is compressed in that once everything has been reduced to 'bits' of information, it becomes simultaneously accessible. Space is compressed in that once everything has been reduced to 'bits' of information, it can be conveyed from A to B with the speed of light. As a result of digitization, everything is in the here and now. Before very long, the whole world will be on disk. Salvation is but a modem away. The digitization process is often seen in terms of (information) technology. That is to say, one hears a lot of talk about the digital media, about computer hardware, about the modem, mobile phone, dictaphone, remote control, buzzer, data glove and the cable or satellite links in between. Besides, our heads are spinning from the progress made in the field of software, in which multimedia applications, with their integration of text, image and sound, especially attract our attention. But digitization is not just a question of technology, it also involves a cultural reorganization. The question is not just what the cultural implications of digitization will be, but also why our culture should give rise to digitization in the first place. Culture is not simply a function of technology; the reverse is surely also true. Anyone who thinks about cultural implications, is interested in the effects of the computer. And indeed, those effects are overwhelming, providing enough material for endless speculation. The digital paradigm will entail a new image of humankind and a further dilution of the notion of social perfectibility; it will create new notions of time and space, a new concept of cause and effect and of hierarchy, a different sort of public sphere, a new view of matter, and so on. In the process it will indubitably alter our environment. Offices, shopping centres, dockyards, schools, hospitals, prisons, cultural institutions, even the private domain of the home: all the familiar design types will be up for review. Fascinated, we watch how the new wave accelerates the process of social change. The most popular sport nowadays is 'surfing' - because everyone is keen to display their grasp of dirty realism. But there is another way of looking at it: under what sort of circumstances is the process of digitization actually taking place? What conditions do we provide that enable technology to exert the influence it does? This is a perspective that leaves room for individual and collective responsibility. Technology is not some inevitable process sweeping history along in a dynamics of its own. Rather, it is the result of choices we ourselves make and these choices can be debated in a way that is rarely done at present: digitization thanks to or in spite of human culture, that is the question. In addition to the distinction between culture as the cause or the effect of digitization, there are a number of other distinctions that are accentuated by the computer. The best known and most widely reported is the generation gap. It is certainly stretching things a bit to write off everybody over the age of 35, as sometimes happens, but there is no getting around the fact that for a large group of people digitization simply does not exist. Anyone who has been in the bit business for a few years can't help noticing that mum and dad are living in a different place altogether. (But they, at least, still have a sense of place!) In addition to this, it is gradually becoming clear that the age-old distinction between market and individual interests are still relevant in the digital era. On the one hand, the advance of cybernetics is determined by the laws of the marketplace which this capital-intensive industry must satisfy. Increased efficiency, labour productivity and cost-effectiveness play a leading role. The consumer market is chiefly interested in what is 'marketable': info- and edutainment. On the other hand, an increasing number of people are not prepared to wait for what the market has to offer them. They set to work on their own, appropriate networks and software programs, create their own domains in cyberspace, domains that are free from the principle whereby the computer simply reproduces the old world, only faster and better. Here it is possible to create a different world, one that has never existed before. One, in which the Other finds a place. The computer works out a new paradigm for these creative spirits. In all these distinctions, architecture plays a key role. Owing to its many-sidedness, it excludes nothing and no one in advance. It is faced with the prospect of historic changes yet it has also created the preconditions for a digital culture. It is geared to the future, but has had plenty of experience with eternity. Owing to its status as the most expensive of arts, it is bound hand and foot to the laws of the marketplace. Yet it retains its capacity to provide scope for creativity and innovation, a margin of action that is free from standardization and regulation. The aim of RealSpace in QuickTimes is to show that the discipline of designing buildings, cities and landscapes is not only a exemplary illustration of the digital era but that it also provides scope for both collective and individual activity. It is not just architecture's charter that has been changed by the computer, but also its mandate. RealSpace in QuickTimes consists of an exhibition and an essay.

title Modelling for eye level composition; design media experiments in an educational setting.
source Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary In order to simulate the visual effects of designs at eye level, it is necessary to construct models from which (sequences of) images can be taken. This holds true for both Optical Endoscopy and Computer Aided Visualisation techniques. In what ways can an eye level approach stimulate spatial awareness and create insights into the workings of a design concept? Can Endoscopic methods be used effectively as a creative environment for design decision-making and teamwork and even to stimulate the generation of new design ideas? How should modelmaking be considered if it is to be of use in an ‘impatient’ design process, and how can students be made aware of the opportunities of both direct eye level observations from design models and of the more sophisticated endoscopic imaging techniques? This paper explores the theme of eye level modelling by focusing on a number of formal exercises and educational experiments carried out by the Delft Media group in recent years. An attempt is made to describe and evaluate these experiences, in order to draw conclusions and to signal possible new opportunities for eye level composition for the benefit of both design education and practice...

title Artificial intelligence and networking in integrated building management systems
source Automation in Construction 6 (5-6) (1997) pp. 481-498
summary In recent years the emphasis has moved towards integrating all a building's systems via centralised building management systems (BMS). To provide a more intelligent approach to the facility management, safety and energy control in building management systems (IBMS), this paper proposes a methodology for integrating the data within a BMS via a single multi-media networking technology and providing the BMS with artificial intelligence (AI) through the use of knowledge-based systems (KBS) technology. By means of artificial intelligence, the system is capable of assessing, diagnosing and suggesting the best solution. This paper outlines how AI techniques can enhance the control of HVAC systems for occupant comfort and efficient running costs based on occupancy prediction. Also load control and load balancing are investigated. Instead of just using pre-programmed load priorities, this work has investigated the use of a dynamic system of priorities which are based on many factors such as area usage, occupancy, time of day and real time environmental conditions. This control strategy which is based on a set of rules running on the central control system, makes use of information gathered from outstations throughout the building and communicated via the building's data-bus.

title Management and Integration of Product Information in Construction: Reality and Future Trends
source The Int. Journal of Construction IT 5(2), pp. 19-46
summary For many years numerous efforts have been spent on the development of standardized approaches for modelling industrial information. During this period stand-alone software tools have been developed in most industries including the Building and Construction sector : Computer Aided Design (CAD) tools, technical software such as software development for energy analysis, project management systems, product databases etc. As this set of computer tools became more and more heterogeneous, the need for communication tools has emerged to enable data to be exchanged between them. Standardising data exchange then becomes a logical step in the improvement of the information management during the whole construction process. The aim of this paper is to put forward the state-of-the art in the domain of product model approaches and standards developments : ISO 10303 STEP, ISO 13584 P-LIB and ISO 15531 MANDATE. We will give a global overview of the existing applications in the construction sector, both in terms of product, or process models, most of them provided by either national or European projects.
