summary	The computer approaches to the discipline of project near the fifties, with the idea that all the systems and processes can be object of mathematical simulation. However in the last times, the computers were used more in drawings than in the projects, “CADrafting is uncommon (...) and CADesign is almost nonexistent...” (STEVEN, 1991). At the same time it happened a surprising approach with to architecture schools. It stimulated more methodological approaches, and the subject moved, placing the computer as element transformer. The computers have really been changing the production and generation of documents, but the question is if it has been altering the method or process of elaboration of ideas. After so much search in direction to the computers it is time of thinking what was gotten with them and the problems that accompanies him. The work search to discuss the subjects where the computer influences in the learning and the students’ development.

title	Is Design Really Social
source	Creative Collaboration in Virtual Communities 1997, ed. A. Cicognani. VC'97. Sydney: Key Centre of Design Computing, Department of Architectural and Design Science, University of Sydney, 8 p.
summary	There are many who will readily agree with Mitchell’s assertion that “the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process.” [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants; that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided; therefore; must permit the best communication and the best social interaction. We think it essential to examine the foundations and assumptions on which software and environments are designed to support collaborative design communication. Of particular interest to us in this paper is the assumption about the “social” nature of design. Early research in computer-assisted design collaborations has jumped immediately into conclusions about communicative models which lead to high-bandwidth video connections as the preferred channel of collaboration. The unstated assumption is that computer-supported design environments are not adequate until they replicate in full the sensation of being physically present in the same space as the other participants (you are not there until you are really there). It is assumed that the real social process of design must include all the signals used to establish and facilitate face-to-face communication; including gestures; body language and all outputs of drawing (e.g. Tang [1991]). In our specification of systems for virtual design communities; are we about to fall into the same traps as drafting systems did?

title	Constructing Three-Dimensional Mental Models from Two-Dimensional Displays
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In the present study we adopted the tasks and the experimental procedures used in a recent series of study by Cooper (1990, 1991) for the purpose of examining how we utilized two-dimensional information in a line-drawing of visual objects to construct the corresponding three-dimensional mental structure represented by the 2-D displays. We expected that the stimulus materials we used avoided some of the problems that Cooper's stimuli had, and with that we examined the effect of complexity on the process of constructing 3-D models from 2-D displays. Such a manipulation helps to elucidate the difficulties of solving problems that require spatial abilities. We also investigated whether or not providing information representing an object viewed from different standpoints would affect the construction of the object's 3-D model. Some researchers have argued that 3-D models, once constructed, should be viewer-independent or viewpoint-invariant, while others have suggested that 3-D models are affected by the viewpoint of observation. Data pertinent to this issue are presented and discussed.

title	The Vector-drawing as a Means to Unravel Architectural Communication in the Past
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q9a
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	Unlike in painting, in architecture one single person never controls the whole process between conception and realization of a building. Ideas of what the building will eventually look like, have to be conveyed from patron to the actual builders, by way of drawings. Generally the architect is the key-figure in this process of communication of visual ideas. Nowadays many architects design their new buildings by using computers and Computer-Aided (Architectural) Design programs like AutoCad and VersaCAD. Just like traditional drawings, all these computer drawings are in fact vector-drawings; a collection of geometrical primitives like lines, circle segments etc. identified by the coordinates of their end points. Vector-based computer programs can not only be used to design the future, but also as a means to unravel the architectural communication in the past. However, using the computer as an analyzing tool for a better comprehension of the past is not as simple as it seems. Historical data from the past are governed by unique features of date and place. The complexity of the past combined with the straightforwardness of the computer requires a pragmatic and basic approach in which the computer acts as a catalytic agent, enabling the scholar to arrive manually at his own - computer-assisted - conclusions. From this it turns out that only a limited number of projects of a morphological kind are suited to contribute to new knowledge, acquired by the close-reading of the information gained by way of meaningful abstraction. An important problem in this respect is how to obtain the right kind of architectural information. All four major elements of the building process - architect, design, drawing and realization - have their own different and gradually shifting interpretations in the past. This goes especially for the run-of-the-mill architecture which makes up the larger part of the historical urban environment. Starting with the architect, one has to realize that only a very limited part of mainstream architecture was designed by architects. In almost all other cases the role of the patron and the actual builder exceeds that of the architect, even to the extent that they designed buildings themselves. The position of design and drawing as means of communication also changed in the past. Until the middle of the nineteenth century drawings were not the chief means of communication between architects and builders, who got the gist of the design from a model, or, encountering problems, simply asked the architect or supervisor. From the nineteenth century onwards the use of drawings became more common, but almost never represented the building entirely "as built". In 1991 I published my Ph.D. thesis: Constructing the past: computerassisted architectural-historical research: the application of image-processing using the computer and Computer-Aided Design for the study of the urban environment, illustrated by the use of treatises in seventeenth-century architecture (Utrecht 1991). Here, a reconstruction of this historical communication process will be presented on the basis of a project studying the use of the Classical orders as prescribed in various architectural treatises, compared to the use of the orders in a specific group of still existing buildings in The Netherlands dating from the late sixteenth and entire seventeenth century. Comparisons were made by using vector-drawings. Both the illustrations in the the treatises and actual buildings were "translated" into computer-drawings and then analyzed.

title	Integration of Existing Programs Using Frames
source	The Computer Integrated Future, CIB W78 Seminar September, 1991. Unnumbered : ill. includes bibliography.
summary	A prototype for computer integrated design/analysis environment is being developed. Due to the nature and size of the author's institution, he opted for compatibility with existing and third party products as well for future developments. Frames are used in Minsky's sense to insulate knowledge and semantics of the tools being integrated. Frames are used again in a more traditional sense insulating components physically. Standards like STEP or AIS were not applied explicitly, but principles behind those standards are reflected in the solution. In the paper an architecture of shallow integration of the tools for integrated structural design is explained in greater detail. Some of the solutions are suggested from the blending of the Object Oriented approach and AI techniques

title	Interactive Scene Walkthrough Using a Physically-Based Virtual Camera
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 511-520
summary	One of the most powerful results of recent advances in graphics hardware is the ability of a computer user to interactively explore a virtual building or landscape. The newest threedimensional input devices, together with high speed 3D graphics workstations, make it possible to view and move through a 3D scene by interactively controlling the motion of a virtual camera. In this paper, we describe how natural and intuitive control of building walkthrough can be achieved by using a physically-based model of the virtual camera's behavior. Using the laws of classical mechanics to create an abstract physical model of the camera, we then simulate the virtual camera motion in real time in response toforce data from the various 3D input devices (e.g. the Spaceball and Polhemus 3Space Digitizer). The resulting interactive behavior of the model is determined by several physical parameters such as mass, moment of inertia, and various friction coefficients which can all be varied interactively, and by constraints on the camera's degrees of freedom. This allows us to explore a continuous range of physically-based metaphors for controlling the camera motion. We present the results of experiments using several of these metaphors for virtual camera motion and describe the effects of the various physical parameters.

source	Reality and Virtual Reality [ACADIA Conference Proceedings / ISBN 1-880250-00-4] Los Angeles (California - USA) October 1991, pp. 1-14
summary	The introduction of physically-based description and simulation methods to issues of building performance (i.e., acoustic, visual, and air quality; thermal comfort, cost, and long-term system integrity) began in the early 1960s as one of the first examples of computer-aided design in architecture. Since that time, the development of commercially-available computer-aided design systems has largely been oriented towards the visualization and representation of the geometry of buildings, while the development of building performance applications has been concerned with approaches to mathematical and physics-based modeling for predictive purposes.

title	AN EVOLUTIONARY ARCHITECTURE
source	London: Architectural Association
summary	In "An Evolutionary Architecture", John Frazer presents an overview of his work for the past 30 years. Attempting to develop a theoretical basis for architecture using analogies with nature's processes of evolution and morphogenesis. Frazer's vision of the future of architecture is to construct organic buildings. Thermodynamically open systems which are more environmentally aware and sustainable physically, sociologically and economically. The range of topics which Frazer discusses is a good illustration of the breadth and depth of the evolutionary design problem. Environmental Modelling One of the first topics dealt with is the importance of environmental modelling within the design process. Frazer shows how environmental modelling is often misused or misinterpreted by architects with particular reference to solar modelling. From the discussion given it would seem that simplifications of the environmental models is the prime culprit resulting in misinterpretation and misuse. The simplifications are understandable given the amount of information needed for accurate modelling. By simplifying the model of the environmental conditions the architect is able to make informed judgments within reasonable amounts of time and effort. Unfortunately the simplications result in errors which compound and cause the resulting structures to fall short of their anticipated performance. Frazer obviously believes that the computer can be a great aid in the harnessing of environmental modelling data, providing that the same simplifying assumptions are not made and that better models and interfaces are possible. Physical Modelling Physical modelling has played an important role in Frazer's research. Leading to the construction of several novel machine readable interactive models, ranging from lego-like building blocks to beermat cellular automata and wall partitioning systems. Ultimately this line of research has led to the Universal Constructor and the Universal Interactor. The Universal Constructor The Universal Constructor features on the cover of the book. It consists of a base plug-board, called the "landscape", on top of which "smart" blocks, or cells, can be stacked vertically. The cells are individually identified and can communicate with neighbours above and below. Cells communicate with users through a bank of LEDs displaying the current state of the cell. The whole structure is machine readable and so can be interpreted by a computer. The computer can interpret the states of the cells as either colour or geometrical transformations allowing a wide range of possible interpretations. The user interacts with the computer display through direct manipulation of the cells. The computer can communicate and even direct the actions of the user through feedback with the cells to display various states. The direct manipulation of the cells encourages experimentation by the user and demonstrates basic concepts of the system. The Universal Interactor The Universal Interactor is a whole series of experimental projects investigating novel input and output devices. All of the devices speak a common binary language and so can communicate through a mediating central hub. The result is that input, from say a body-suit, can be used to drive the out of a sound system or vice versa. The Universal Interactor opens up many possibilities for expression when using a CAD system that may at first seem very strange.However, some of these feedback systems may prove superior in the hands of skilled technicians than more standard devices. Imagine how a musician might be able to devise structures by playing melodies which express the character. Of course the interpretation of input in this form poses a difficult problem which will take a great deal of research to achieve. The Universal Interactor has been used to provide environmental feedback to affect the development of evolving genetic codes. The feedback given by the Universal Interactor has been used to guide selection of individuals from a population. Adaptive Computing Frazer completes his introduction to the range of tools used in his research by giving a brief tour of adaptive computing techniques. Covering topics including cellular automata, genetic algorithms, classifier systems and artificial evolution. Cellular Automata As previously mentioned Frazer has done some work using cellular automata in both physical and simulated environments. Frazer discusses how surprisingly complex behaviour can result from the simple local rules executed by cellular automata. Cellular automata are also capable of computation, in fact able to perform any computation possible by a finite state machine. Note that this does not mean that cellular automata are capable of any general computation as this would require the construction of a Turing machine which is beyond the capabilities of a finite state machine. Genetic Algorithms Genetic algorithms were first presented by Holland and since have become a important tool for many researchers in various areas.Originally developed for problem-solving and optimization problems with clearly stated criteria and goals. Frazer fails to mention one of the most important differences between genetic algorithms and other adaptive problem-solving techniques, ie. neural networks. Genetic algorithms have the advantage that criteria can be clearly stated and controlled within the fitness function. The learning by example which neural networks rely upon does not afford this level of control over what is to be learned. Classifier Systems Holland went on to develop genetic algorithms into classifier systems. Classifier systems are more focussed upon the problem of learning appropriate responses to stimuli, than searching for solutions to problems. Classifier systems receive information from the environment and respond according to rules, or classifiers. Successful classifiers are rewarded, creating a reinforcement learning environment. Obviously, the mapping between classifier systems and the cybernetic view of organisms sensing, processing and responding to environmental stimuli is strong. It would seem that a central process similar to a classifier system would be appropriate at the core of an organic building. Learning appropriate responses to environmental conditions over time. Artificial Evolution Artificial evolution traces it's roots back to the Biomorph program which was described by Dawkins in his book "The Blind Watchmaker". Essentially, artificial evolution requires that a user supplements the standard fitness function in genetic algorithms to guide evolution. The user may provide selection pressures which are unquantifiable in a stated problem and thus provide a means for dealing ill-defined criteria. Frazer notes that solving problems with ill-defined criteria using artificial evolution seriously limits the scope of problems that can be tackled. The reliance upon user interaction in artificial evolution reduces the practical size of populations and the duration of evolutionary runs. Coding Schemes Frazer goes on to discuss the encoding of architectural designs and their subsequent evolution. Introducing two major systems, the Reptile system and the Universal State Space Modeller. Blueprint vs. Recipe Frazer points out the inadequacies of using standard "blueprint" design techniques in developing organic structures. Using a "recipe" to describe the process of constructing a building is presented as an alternative. Recipes for construction are discussed with reference to the analogous process description given by DNA to construct an organism. The Reptile System The Reptile System is an ingenious construction set capable of producing a wide range of structures using just two simple components. Frazer saw the advantages of this system for rule-based and evolutionary systems in the compactness of structure descriptions. Compactness was essential for the early computational work when computer memory and storage space was scarce. However, compact representations such as those described form very rugged fitness landscapes which are not well suited to evolutionary search techniques. Structures are created from an initial "seed" or minimal construction, for example a compact spherical structure. The seed is then manipulated using a series of processes or transformations, for example stretching, shearing or bending. The structure would grow according to the transformations applied to it. Obviously, the transformations could be a predetermined sequence of actions which would always yield the same final structure given the same initial seed. Alternatively, the series of transformations applied could be environmentally sensitive resulting in forms which were also sensitive to their location. The idea of taking a geometrical form as a seed and transforming it using a series of processes to create complex structures is similar in many ways to the early work of Latham creating large morphological charts. Latham went on to develop his ideas into the "Mutator" system which he used to create organic artworks. Generalising the Reptile System Frazer has proposed a generalised version of the Reptile System to tackle more realistic building problems. Generating the seed or minimal configuration from design requirements automatically. From this starting point (or set of starting points) solutions could be evolved using artificial evolution. Quantifiable and specific aspects of the design brief define the formal criteria which are used as a standard fitness function. Non-quantifiable criteria, including aesthetic judgments, are evaluated by the user. The proposed system would be able to learn successful strategies for satisfying both formal and user criteria. In doing so the system would become a personalised tool of the designer. A personal assistant which would be able to anticipate aesthetic judgements and other criteria by employing previously successful strategies. Ultimately, this is a similar concept to Negroponte's "Architecture Machine" which he proposed would be computer system so personalised so as to be almost unusable by other people. The Universal State Space Modeller The Universal State Space Modeller is the basis of Frazer's current work. It is a system which can be used to model any structure, hence the universal claim in it's title. The datastructure underlying the modeller is a state space of scaleless logical points, called motes. Motes are arranged in a close-packing sphere arrangement, which makes each one equidistant from it's twelve neighbours. Any point can be broken down into a self-similar tetrahedral structure of logical points. Giving the state space a fractal nature which allows modelling at many different levels at once. Each mote can be thought of as analogous to a cell in a biological organism. Every mote carries a copy of the architectural genetic code in the same way that each cell within a organism carries a copy of it's DNA. The genetic code of a mote is stored as a sequence of binary "morons" which are grouped together into spatial configurations which are interpreted as the state of the mote. The developmental process begins with a seed. The seed develops through cellular duplication according to the rules of the genetic code. In the beginning the seed develops mainly in response to the internal genetic code, but as the development progresses the environment plays a greater role. Cells communicate by passing messages to their immediate twelve neighbours. However, it can send messages directed at remote cells, without knowledge of it's spatial relationship. During the development cells take on specialised functions, including environmental sensors or producers of raw materials. The resulting system is process driven, without presupposing the existence of a construction set to use. The datastructure can be interpreted in many ways to derive various phenotypes. The resulting structure is a by-product of the cellular activity during development and in response to the environment. As such the resulting structures have much in common with living organisms which are also the emergent result or by-product of local cellular activity. Primordial Architectural Soups To conclude, Frazer presents some of the most recent work done, evolving fundamental structures using limited raw materials, an initial seed and massive feedback. Frazer proposes to go further and do away with the need for initial seed and start with a primordial soup of basic architectural concepts. The research is attempting to evolve the starting conditions and evolutionary processes without any preconditions. Is there enough time to evolve a complex system from the basic building blocks which Frazer proposes? The computational complexity of the task being embarked upon is not discussed. There is an implicit assumption that the "superb tactics" of natural selection are enough to cut through the complexity of the task. However, Kauffman has shown how self-organisation plays a major role in the early development of replicating systems which we may call alive. Natural selection requires a solid basis upon which it can act. Is the primordial soup which Frazer proposes of the correct constitution to support self-organisation? Kauffman suggests that one of the most important attributes of a primordial soup to be capable of self-organisation is the need for a complex network of catalysts and the controlling mechanisms to stop the reactions from going supracritical. Can such a network be provided of primitive architectural concepts? What does it mean to have a catalyst in this domain? Conclusion Frazer shows some interesting work both in the areas of evolutionary design and self-organising systems. It is obvious from his work that he sympathizes with the opinions put forward by Kauffman that the order found in living organisms comes from both external evolutionary pressure and internal self-organisation. His final remarks underly this by paraphrasing the words of Kauffman, that life is always to found on the edge of chaos. By the "edge of chaos" Kauffman is referring to the area within the ordered regime of a system close to the "phase transition" to chaotic behaviour. Unfortunately, Frazer does not demonstrate that the systems he has presented have the necessary qualities to derive useful order at the edge of chaos. He does not demonstrate, as Kauffman does repeatedly, that there exists a "phase transition" between ordered and chaotic regimes of his systems. He also does not make any studies of the relationship of useful forms generated by his work to phase transition regions of his systems should they exist. If we are to find an organic architecture, in more than name alone, it is surely to reside close to the phase transition of the construction system of which is it built. Only there, if we are to believe Kauffman, are we to find useful order together with environmentally sensitive and thermodynamically open systems which can approach the utility of living organisms.

title	CONSTRUCTING THE AMORPHOUS
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	Constructing the Amorphous entails the ongoing research into a concept which aims to develop a new understanding for Art, Design and Architecture within society. Rigid, reductivist and confrontational methods based on static geometry, prejudice and competition are to be replaced by dynamic, interdisciplinary and integrative models. In his current art practice the author simulates existing architectural spaces whose interior are re-designed into sculpted environments, based on creative irregularity rather than idealised geometry. All the computer simulated “soft” environments can be realised on an architectural scale as temporary installations with the curved surfaces approximated through planar polygons cut from sheet materials. Within this framework the Darren Knight Gallery Project represents the most recently example. The paper discusses furthermore various 3D modeling options, such as standard CAD representations, high quality rendered video walk-throughs, VRML models and physically produced, full-scale models, made of corrugated cardboard. The cost and equipment requirements necessary for full-scale modeling in cardboard are outlined.

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.

source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.815-823
summary	Due to improving technology and global competition today sky is the only limit for high towers of metropolitan areas. The increase in number of high rise has been ruining the silhouette of cities all over the world like Istanbul, whose identity and image have also been destroyed by skyscrapers dominating the seven slopes on which it was once built. The urbanization in Istanbul has somehow become homogenous and destructive over the topography. Despite of raising debates on the critical issue now and then, no analytical approach has ever been introduced. The research therefore, aims to analyze the change of Bosphorus silhouette caused by the emergence of high rise blocks in Zincirlikuyu-Maslak route since it was defined as a Central Business District and a high rise development area by Bosphorus Conservation Law in 1991. ArcGIS Desktop software and its analyst extensions are used for mapping, analyzing and evaluating the urban development within years. The application is considered to be the initial step for a decision support system which will assist in assigning ground for high rise buildings in Istanbul.

source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 549-566
summary	This paper focuses on the visualization of historical architecture. The application of new Computer-Aided- Architectural-Design techniques for visualization on micro computers provides a technique for reconstructing and analyzing architectural objects from the past. The pilot project describes a case study in which the historical transformation of a town will be analyzed by using three- dimensional CAD models in combination with bitmap textures. The transformation of the historic town will be visualized in a space-time computer model in which bitmap textures enable us to display complex and relatively large architectural objects in detail. This three-dimensional descriptive model allows us to survey and analyze the history of architecture in its reconstructed context. It also provides a medium for researching the dynamics of urban management, since new combinations and arrangements with the individual architectural objects can be created. In this way, a new synthesis of the graphic material can reveal typologies and the architectural ordering system of a town.

title	Design Tool Integration: Model Flexibility for the Building Profession
source	Proceedings of Building Systems Automation - Integration, University of Wisconsin-Madison
summary	The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by simulation tools, can be used to converse with knowledge-based systems. We consider the types of mappings that occur in the often different views of a building held by these two classes of design tools. This leads us to examine the need for multiple views of a common building model. We then extend our analysis from the views required by simulation and knowledge-based systems, to those required by different segments of the building profession (e.g. architects, engineers, developers, etc.) to converse with such an integrated system. This indicates a need to provide a flexible method of accessing data in the common building model to facilitate use by different building professionals with varying specialities and levels of expertise.

title	ICAtect: Integrating Design Tools for Preliminary Architectural Design
source	Wellington, New Zealand: Computer Science Department, Victoria University
summary	ICAtect is a knowledge based system that provides an interface between expert systems, simulation packages and CAD systems used for preliminary architectural design. This thesis describes its structure and development.The principal work discussed in this thesis involves the formulation of a method for representing a building. This is developed through an examination of a number of design tools used in architectural design, and the ways in which each of these describe a building.Methods of enabling data to be transferred between design tools are explored. A Common Building Model (CBM), forming the core of the ICAtect system, is developed to represent the design tools knowledge of a building. This model covers the range of knowledge required by a large set of disparate design tools used by architects at the initial design stage.Standard methods of integrating information from the tools were examined, but required augmentation to encompass the unusual constraints found in some of the design tools. The integration of the design tools and the CBM is discussed in detail, with example methods developed for each type of design tool. These example methods provide a successful way of moving information between the different representations. Some problems with mapping data between very different representations were encountered in this process, and the solutions or ideas for remedies are detailed. A model for control and use of ICAtect is developed in the thesis, and the extensions to enable a graphical user interface are discussed.The methods developed in this thesis demonstrate the feasibility of an integrated system of this nature, while the discussion of future work indicates the scope and potential power of ICAtect.

summary	To begin with, I would like to say a few words about the problem of alienation of modern technologies which we also inevitably faced while starting teaching CAD at our department. Quite often nowadays a technology becomes a fetish as a result of lack of clear goals in human mind. There are multiple technologies without sense of purpose which turned into pure experiments. There is always the danger of losing purposeness and drifting toward alienation. The cause of the danger lies in forgetting about original goals while mastering and developing the technology. Eventually the original idea is ignored and a great gap appears between technical factors and creativity. We had the danger of alienation in mind when preparing the CAAD curriculum. Trying to avoid the tension between technical and creative elements we agreed not to introduce CAD too soon then the fourth year of studies and continue it for two semesters. One thing was clear - we should not teach the technique of CAD but how to design using a computer as a medium. Then we specified projects. The first was called "The bathroom I dream of" and meant to be a 2D drawing. The four introductory meetings were in fact teaching foundations of DOS, then a specific design followed with the help of AutoCAD program. In the IX semester, for example, it was "A family house" (plans, facades, perspective). "I have to follow them - I am their leader" said L.J. Peter in "The Peter's Prescription". This quotation reflects exactly the situation we find ourselves in teaching CAAD at our department. It means that ever growing students interest in CAAD made us introduce changes in the curriculum. According to the popular saying, "The more one gets the more one wants", so did we and the students feel after the first semester of teaching CAD. From autumn 1991 CAAD classes will be carried from the third year of studying for two consecutive years. But before further planning one major steep had to be done - we decided to reverse the typical of the seventies approach to the problem when teaching programming languages preceded practical goals hence discouraging many learners.

title	Integration of Simulation into the Building Design Process
source	J.A. Clarke, J.W. Mitchell, and R.C. Van de Perre (eds.), Proceedings, Building Simulation '91 IBPSA Conference, pp. 367-374
summary	We describe the need for a joint effort between design researchers and simulation tool developers in formulating procedures and standards for integrating simulation into the building design process. We review and discuss current efforts in the US and Europe in the development of next-generation simulation tools and design integration techniques. In particular, we describe initiatives in object-oriented simulation environments (including the US Energy 'Kernel System, the Swedish Ida system, the UK Energy Kernel System, and the French ZOOM program.) and consider the relationship of these environments to recent R&D initiatives in design integration (the COMBINE project in Europe and the AEDOT project in the US).

title	XNET2 - Methodical Design of Local Area Networks in Buildings - An Application of the A4 Intelligent Design Tool
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 443-450
summary	XNET2 is a prototype program, that helps network planners to design Ethernet-conform data-networks for sites and buildings. It is implemented as an example application of the ARMILLA4 Intelligent Design Tool under Knowledge Craft. It is based on a knowledge acquisition phase with experts from DECsite, the network-branch of DEC. The ARMILLA Design Tool is developed on the basis of Fritz Haller's ARMILLA ' a set of geometrical and operational rules for the integration of technical ductwork into a building's construction.

title	Computers for Architects - Only a Tool?
doi	https://doi.org/10.52842/conf.ecaade.1991.x.i9j
source	Experiences with CAAD in Education and Practice [eCAADe Conference Proceedings] Munich (Germany) 17-19 October 1991
summary	The paper states that, as a result of the schism between architecture as art and engineering as rationalism, the architectural community underestimates the computer as tool with a potential to substantially enlarge the possibilities of building design. It is claimed that the computer could serve as coordination tool for the ruptured design process, as a virtual workbench where all design disciplines sit together and develop their designs in enhanced conscience of what the whole design demands. The paper then concludes, that to develop such software tools, architects must participate in the development of software and may no longer be restricted to the role of applicants, especially during their universitary instruction. The corresponding research and training facilities at the University of Karlsruhe, Faculty of Architecture are described.
