summary Computer applications in design have pursued two main development directions: analytical modelling and information technology. The former line has produced a large number of tools for reality simulation (i.e. finite element models), the latter is producing an equally large amount of advances in conceptual design support (i.e. artificial intelligence tools). Nevertheless we can trace rare interactions between computation models related to those different approaches. This lack of integration is the main reason of the difficulty of CAAD application to the preliminary stage of design, where logical and quantitative reasoning are closely related in a process that we often call 'qualitative evaluation'. This paper briefly surveys the current development of qualitative physical models applied in design and propose a general approach for modelling physical behaviour by means of Bayesian network we are employing to develop a tutoring and coaching system for natural ventilation preliminary design of halls, called VENTPad. This tool explores the possibility of modelling the causal mechanism that operate in real systems in order to allow a number of integrated logical and quantitative inference about the fluid-dynamic behaviour of an hall. This application could be an interesting connection tool between logical and analytical procedures in preliminary design aiding, able to help students or unskilled architects, both to guide them through the analysis process of numerical data (i.e. obtained with sophisticate Computational Fluid Dynamics software) or experimental data (i.e. obtained with laboratory test models) and to suggest improvements to the design.

title Applying Daylighting Simulation in Architectural Studio Education
source Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 255-258

summary Computer generated simulation results are not necessarily valid design solutions. In some cases, unscientific “simulation” applications have misled designers to believe the “illusion” rendered by the system. This paper presents two case studies to highlight the pedagogy of architectural daylighting simulation. Both are located in Hong Kong’s highdensity urban context. Hong Kong is a small city, covering 1,097 square km with a population of 6.8 million. Mountains and hills dominate the topography, and more than 70% of the land is reserved for country parks. Property constraints encourage dense, high-rise construction and building on steep slopes. This creates a complex environment for daylighting design. Although the Buildings Ordinance specifies minimum standards for natural light and ventilation, residents have complained about the deterioration of their lighting condition in recent years. Challenged by the constraints imposed by Hong Kong’s physical environment, there is a need for students and professionals to explore computer simulation to integrate daylighting strategy into architectural and urban design.

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.

summary The work is developed applying the perspective restitution method, based on the photographic survey of buildings. It researches the accuracy selection of the instruments, that should be effective, easy to manage, low cost and it allow fast results so as to let us compile a digital graphic data bases of the chosen works. The aim of the project is to elaborate graphic documents not only from the paradigmatic works but also from domestic architecture, so important in the consolidation of city. The idea is to include new concepts about the use of digital devices and instruments. The emphasis is on the production of a low cost graphic documents, obtained with standard hardware and software used at our University. The architectural works selected belongs to the Rosario’s Rationalist heritage that have to be completed at the Municipal Archive.

summary Our paper presents recent developments of a co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France), specialised in computer science and the HAiKZ Institute of Krakow's Faculty of Architecture, specialised in architectural heritage and conservation. Before undertaking any action to a listed building or interventions in its neighbourhood, it is vital to gain a clear understanding of the building in question. Numerous heterogeneous data detained by diverse institutions has to be handled. This process can be greatly eased by enhanced classification of the information. The development we present is a multidisciplinary platform independent information tool dedicated to education and research. SOL uses an http protocol centred computer architecture connecting a relational database, a VRML 2.0 representation module and a web search interface. It allows searches and updating of the database through a standard text based interface, a VRML 2.0 graphical module and a thematic interface. SOL is experienced on the urban fabric of the Main Square (Rynek Gówny) in Kraków. The choice of a web-centred development, both in the search and updating interface and in the representation module provides platform independence and distant access to the database, and enables successive contributions of students or researchers.

summary Jaron Lanier is a major spokesperson of our society's hottest new technology: VR or virtual reality. He expressed his faith in the VR movement in this quote which appears in The User's Guide to the New Edge published by Mondo 2000. In its most technical sense, VR has attracted the attention of politicians in Washington who wonder if yet another technology developed in the United States will find its application across the globe in Asia. In its most human element, an entire "cyberpunk movement" has appealed to young minds everywhere as a seemingly safe form of hallucination. As architecture students, educators, and practitioners around the world are becoming attracted to the possibilities of VR technology as an extension of 3D modeling, visualization, and animation, it is appropriate to consider an overview of virtual reality.

In virtual reality a user encounters a computersimulated environment through the use of a physical interface. The user can interact with the environment to the point of becoming a part of the experience, and the experience becomes reality. Natural and

instinctive body movements are translated by the interface into computer commands. The quest for perfection in this human-computer relationship seems to be the essence of virtual reality technology.

To begin to capture the essence of virtual reality without first-hand experience, it is helpful to understand two important terms: presence and immersion. The sense of presence can be defined as the degree to which the user feels a part of the actual environment. The more reality the experience provides, the more presence it has. Immersion can be defined as the degree of other simulation a virtual reality interface provides for the viewer. A highly immersive system might provide more than just visual stimuli; for example, it may additionally provide simulated sound and motion, and simultaneously prevent distractions from being present.

title Towards Fully Automatic Generation of City Models
source IAPRS Vol. XXXIII, Part B3/1, Comm. III [ISPRS Congress], pp. 85-92
summary Once thought of being useful primarily for planning the location of telecommunication antennas, it has become clear in the meantime that three-dimensional city models are of importance in their own right. This paper presents some of our latest results on the reconstruction of building models from laser scanning DSM’s and digital ground plans. First, we show how buildings can be reconstructed from ground plans and generalize the standard straight skeleton algorithm. In a second step, we introduce the information which can be obtained from DSM segmentation in order to recover building structures which cannot be inferred directly from the ground plan. The work presented in this paper is actually part of our larger ATOP approach, a new framework for the fully automatic generation of city models.

title Spatial reasoning: improving computational efficiency
source Automation in Construction 9 (4) (2000) pp. 361-367
summary When spatial data is analysed the result is often very computer intensive: even by the standards of contemporary technologies, the machine power needed is great and the processing times significant. This is particularly so in 3-D and 4-D scenarios. What we describe here is a technique, which tackles this and associated problems. The technique is founded in the idea of quad-tesseral addressing; a technique, which was originally applied to the analysis of atomic structures. It is based on ideas concerning Hierarchical clustering developed in the 1960s and 1970s to improve data access time [G.M. Morton, A computer oriented geodetic database and a new technique on file sequencing, IBM Canada, 1996.], and on atomic isohedral (same shape) tiling strategies developed in the 1970s and 1980s concerned with group theory [B. Grunbaum, G.C. Shephard, Tilings and Patterns, Freeman, New York, 1987.]. The technique was first suggested as a suitable representation for GIS in the early 1980s when the two strands were brought together and a tesseral arithmetic applied [F.C. Holdroyd, The Geometry of Tiling Hierarchies, Ars Combanitoria 16B (1983) 211–244.; S.B.M. Bell, B.M. Diaz, F.C. Holroyd, M.J.J. Jackson, Spatially referenced methods of processing raster and vector data, Image and Vision Computing 1 (4) (1983) 211–220.; Diaz, S.B.M. Bell, Spatial Data Processing Using Tesseral Methods, Natural Environment Research Council, Swindon, 1986.]. Here, we describe how that technique can equally be applied to the analysis of environmental interaction with built forms. The way in which the technique deals with the problems described is first to linearise the three-dimensional (3-D) space being investigated. Then, the reasoning applied to that space is applied within the same environment as the definition of the problem data. We show, with an illustrative example, how the technique can be applied. The problem then remains of how to visualise the results of the analysis so undertaken. We show how this has been accomplished so that the 3-D space and the results are represented in a way which facilitates rapid interpretation of the analysis, which has been carried out.

summary The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

title A digital Procedure of Building Construction: A practical project

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

summary The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

title The management and visualisation of 3-dimensional models using a spatial database
source CIDAC, Volume 2 Issue 4 November 2000, pp. 225-235
summary Each year, computer-aided architectural design (CAAD) systems in common use are enhanced and gain facilities that ease 3-dimensional (3D) modelling. Consequently, large complex datasets are increasinly common during the creation and management of 3D models of buildings and urban areas. Uses for such models range from the automatic generation of drawings and schedules to virtual reality (VR) and visualisation across the web. Geographic information systems (GISs) are optimised for the management and retrieval of spatial data and may be used to assist both management and visualisation of large 3D datasets using open standards, such as the ISO standard virtual reality modelling langauge (VRML). Experience gained in the use of such systems indicates a need for specific procedures for recording 3D data and creating linkages to other information. It is suggested that these procedures are applicable to a broad range of such models.

summary The spread of the Internet has spurred the recent growth in e-commerce. E-commerce impinges on design in many ways, not least in encouraging the development of new tools for the presentation of product information: that is, information about the products that are used in design projects. (In the case of building design this might include information about standard doors, windows and fittings.) In this paper we present our development of three experimental tools for presenting and organising product information. The tools represent stages in the evolution of a prototype we call PLA(id) (Product Library Assistant – Intranet for Designers) involving the use of multimedia authoring, Java, and mobile computing. We discuss our experimental prototypes under several headings derived from what are commonly considered the key features of e-commerce: the marketplace, collaboration (the electronic marketplace as a community), geography (and geographical boundaries), navigation, regulation, integration and media (how in some cases e-commerce provides both the medium of transaction and the medium of delivery). So this account of our experimentation with product information tools provides a way of reviewing issues raised by e-commerce and their importance for design decision support systems.

summary It is all too common for technology companies to seek a new route to solving the same problem but for the most part the solutions address the effect and not the cause. The good old-fashioned pencil is the perfect example where inventors have sought to design-out the effect of the inherent brittleness of lead. Traditionally different methods of sharpening were suggested and more recently the propelling pencil has reigned king, the lead being supported by the dispensing sleeve thus reducing the likelihood of breakage. Developers convinced by the Single Building Model approach to design development have each embarked on a difficult journey to create an easy to use feature packed application. Unfortunately it seems that the two are not mutually compatible if we are to believe what we see emanating from Technology giants Autodesk in the guise of Architectural Desktop 3. The effect of their development is a feature rich environment but the cost and in this case the cause is a tool which is far from easy to use. However, this is only a small part of a much bigger problem, Interoperability. You see when one designer develops a model with one tool the information is typically locked in that environment. Of course the geometry can be distributed and shared amongst the team for use with their tools but the properties, or as often misquoted, the intelligence is lost along the way. The effect is the technological version of rubble; the cause is the low quality of data-translation available to us. Fortunately there is one company, which is making rapid advancements on the whole issue of collaboration, and data sharing. An old timer (Graphisoft - famous for ArchiCAD) has just donned a smart new suit, set up a new company called GDL Technology and stepped into the ring to do battle, with a difference. The difference is that GDL Technology does not rely on conquering the competition, quite the opposite in fact their success relies upon the continued success of all the major CAD platforms including AutoCAD, MicroStation and ArchiCAD (of course). GDL Technology have created a standard data format for manufacturers called GDL Objects. Product manufacturers such as Velux are now able to develop product libraries using GDL Objects, which can then be placed in a CAD model, or drawing using almost any CAD tool. The product libraries can be stored on the web or on CD giving easy download access to any building industry professional. These objects are created using scripts which makes them tiny for downloading from the web. Each object contains 3 important types of information: · Parametric scale dependant 2d plan symbols · Full 3d geometric data · Manufacturers information such as material, colour and price Whilst manufacturers are racing to GDL Technologies door to sign up, developers and clients are quick to see the benefit too. Porsche are using GDL Objects to manage their brand identity as they build over 300 new showrooms worldwide. Having defined the building style and interior Porsche, in conjunction with the product suppliers, have produced a CD-ROM with all of the selected building components such as cladding, doors, furniture, and finishes. Designing and detailing the various schemes will therefore be as straightforward as using Lego. To ease the process of accessing, sizing and placing the product libraries GDL Technology have developed a product called GDL Object Explorer, a free-standing application which can be placed on the CD with the product libraries. Furthermore, whilst the Object Explorer gives access to the GDL Objects it also enables the user to save the object in one of many file formats including DWG, DGN, DXF, 3DS and even the IAI's IFC. However, if you are an AutoCAD user there is another tool, which has been designed especially for you, it is called the Object Adapter and it works inside of AutoCAD 14 and 2000. The Object Adapter will dynamically convert all GDL Objects to AutoCAD Blocks during placement, which means that they can be controlled with standard AutoCAD commands. Furthermore, each object can be linked to an online document from the manufacturer web site, which is ideal for more extensive product information. Other tools, which have been developed to make the most of the objects, are the Web Plug-in and SalesCAD. The Plug-in enables objects to be dynamically modified and displayed on web pages and Sales CAD is an easy to learn and use design tool for sales teams to explore, develop and cost designs on a Notebook PC whilst sitting in the architects office. All sales quotations are directly extracted from the model and presented in HTML format as a mixture of product images, product descriptions and tables identifying quantities and costs. With full lifecycle information stored in each GDL Object it is no surprise that GDL Technology see their objects as the future for building design. Indeed they are not alone, the IAI have already said that they are going to explore the possibility of associating GDL Objects with their own data sharing format the IFC. So down to the dirty stuff, money and how much it costs? Well, at the risk of sounding like a market trader in Petticoat Lane, "To you guv? Nuffin". That's right as a user of this technology it will cost you nothing! Not a penny, it is gratis, free. The product manufacturer pays for the license to host their libraries on the web or on CD and even then their costs are small costing from as little as 50p for each CD filled with objects. GDL Technology has come up trumps with their GDL Objects. They have developed a new way to solve old problems. If CAD were a pencil then GDL Objects would be ballistic lead, which would never break or loose its point. A much better alternative to the strategy used by many of their competitors who seek to avoid breaking the pencil by persuading the artist not to press down so hard. If you are still reading and you have not already dropped the magazine and run off to find out if your favorite product supplier has already signed up then I suggest you check out the following web sites www.gdlcentral.com and www.gdltechnology.com. If you do not see them there, pick up the phone and ask them why.

summary The present graphic computer system allows defining high-level shape problems with great freedom. In free-form surface modeling it comes to be a good reason to develop an example that shows, which is the best way to create, modify and control complex free-form shapes in three-dimensional architectonic virtual modeling. The parameters of Bezier curves are not simple. But the use of Splines curves let us a friendly free form curves management with a great designer performance level. Unfortunately, the standard computer graphic tools to control these entities have a lot of variations, and normally create an unclear and confuse interface for generic users without several knowledge of mathematics and geometry. With the help of an example, this paper expose the use of computer graphics to make models of architectonic buildings with complex shapes that contains free-form surfaces. At the same time, it is an evaluation of how the standard CAD software processes this problem.

summary Description of class research from 1997-2 to 2000-1 in “Applied Computing in Architecture” conducted in the sixth semester of the Architecture Program at Faculdade de Belas Artes de São Paulo. The study is intended to analyze, evaluate and discover new paradigms in the introduction/application of class methodologies of teaching the use of computer in the design process. Our intention is to verify the students natural understanding of the principles of 3D digital modeling by introducing new tools for defining space and form, using the computer as a communication/representation system, and not only as a mimetized production tool. The challenge was to find a natural syntony between the digital projectual process and the learning process. At the end of each semester we evaluated the results and redirected the class proposals.

title Creative computer aided architectural design An internal approach to the design process
source University of Oulu (Finland)
summary This survey can be seen as quite multidisciplinary research. The basis for this study has been inapplicability of different CAD user interfaces in architectural design. The objective of this research is to improve architectural design from the creative problem-solving viewpoint, where the main goal is to intensify architectural design by using information technology. The research is linked to theory of methods, where an internal approach to design process means studying the actions and thinking of architects in the design process. The research approach has been inspired by hermeneutics. The human thinking process is divided into subconscious and conscious thinking. The subconscious plays a crucial role in creative work. The opposite of creative work is systematic work, which attempts to find solutions by means of logical inference. Both creative and systematic problem solving have had periods of predominance in the history of Finnish architecture. The perceptions in the present study indicate that neither method alone can produce optimal results. Logic is one of the tools of creativity, since the analysis and implementation of creative solutions require logical thinking. The creative process cannot be controlled directly, but by creating favourable work conditions for creativity, it can be enhanced. Present user interfaces can make draughting and the creation of alternatives quicker and more effective in the final stages of designing. Only two thirds of the architects use computers in working design, even the CAD system is being acquired in greater number of offices. User interfaces are at present inflexible in sketching. Draughting and sketching are the basic methods of creative work for architects. When working with the mouse, keyboard and screen the natural communication channel is impaired, since there is only a weak connection between the hand and the line being drawn on the screen. There is no direct correspondence between hand movements and the lines that appear on the screen, and the important items cannot be emphasized by, for example, pressing the pencil more heavily than normally. In traditional sketching the pen is a natural extension of the hand, as sketching can sometimes be controlled entirely by the unconscious. Conscious efforts in using the computer shift the attention away from the actual design process. However, some architects have reached a sufficiently high level of skill in the use of computer applications in order to be able to use them effectively in designing without any harmful effect on the creative process. There are several possibilities in developing CAD systems aimed at architectural design, but the practical creative design process has developed during a long period of time, in which case changing it in a short period of time would be very difficult. Although CAD has had, and will have, some evolutionary influences on the design process of architects as an entity, the future CAD user interface should adopt its features from the architect's practical and creative design process, and not vice versa.

title Possibilities and limitations of CFD simulation for indoor climate analysis
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary With the democratization of information and communication technologies, simulation techniques that used to be computationally expensive and time-consuming are becoming feasible instruments for the analysis of architectural design. Simulation is an indispensable ingredient of the descriptive design approach, which provides the designer with precise and accurate projections of the performance and behavior of a design. The paper describes the application of a particular class of simulation techniques, computational fluid dynamics (CFD), to the analysis and evaluation of indoor climate. Using two different CFD systems as representatives of the class, we describe: relevant computational possibilities and limitations of CFD simulation; the accessibility of CFD simulation for architects, especially concerning the handling of simulation variables; the compatibility of CFD representations of built space with similar representations in standard CAD and modeling systems, including possibilities for feedback; The relations between geometric representation and accuracy / precision in CFD simulation. We propose that CFD simulation can become an operational instrument for the designer, provided that CFD simulation does not become a trial and error game trying to master computational techniques. A promising solution to this problem is the use of case based reasoning. A case base of analyzed, evaluated and verified buildings provides a flexible source of information (guidance and examples) for both the CFD simulation and the designer.
