summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title The Role of Computers in Synchronous Collaborative Design
source Proceedings of the 14th International Congress on Cybernetics. Namur, Belgium: International Association for Cybernetics, 1995, pp. 71-76
summary In this paper we discuss the role of computers in supporting real-time synchronous design among geographically dispersed team members using the global network of computers known as the Internet. To enable efficient and functional synchronous design activity, we advocate a new generation of design-oriented software that combines collaboration technologies with a meaningful and parsimonious representation scheme. We are particularly interested in supporting the early design phases, wherein many of the most important decisions are made and collaboration is most important. These activities are crucial to the evolution and quality of the final design, and they are receptive to and can benefit from computer support. Furthermore, these are precisely the areas where current CAD systems are weakest. As a general theoretical direction, our emphasis is not on integrated databases, but rather on shared protocols of interaction that are independent of implementation and storage schemes. Our first experimental phase involved the simultaneous development and testing of prototypes for a Synchronous Collaborative Design Environment (SYCODE) on heterogeneous computer systems at two geographically dispersed sites. The applications were developed independently, based on a verbal description of protocols, with minimal sharing of actual source code. Though their user interfaces and implementation details are different, these prototypes allow multiple users to share a virtual design space - both within and between the remote sites - in which to create and manipulate architectural elements.

title Architecture not Aided – Architecture Transformed
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 193-207
summary Permeating of new technologies (computer aided design) into architectural design causes essential changes in its structure. It is the process, set of mutually interrelated different social, political, cultural occurrences, which happen in the present time. Everything what is new, brings either fear or unreliable expectations. The reflection is needed to name what we will have to deal with in architecture. Architecture is not a stable sphere, and as other disciplines is subject to processes of change, which result from the specificity of the time. We need to be aware of the consequences these processes could cause. I located them in six general fields: 1.) Transformation of the tool traditional tools - set of singular, autonomous, mono-functional devices, which together make the environment; computer - one tool consisting of non-autonomous internal and external units, multifunctional; itself it is the environment, system; 2.) Transformation of the medium. As the medium is the message (M.McLuhan), so the essence of media is transmission. Traditional transmission in architectural design is direct (transmission is equivalent to recording, notation), computer based transmission is indirect (transmission is not equivalent to recording); 3.) Transformation of perception, imagination and thinking. Perception - in the process of design directly relates to media Indirect transmission - causes also rupture in direct relation between record and perception (mainly in modelling); simulated object is a stage in the process. Imagination, thinking - influenced with perception, with data transmitted from the medium - can be seen as inspiration; 4.) Transformation of cooperation and communication. It is to be done by elimination of some of intermediate stages in the design process and use of multimedial communication systems (Internet); 5.) Transformation of methodology. Same as in 4 with the possibility of simultaneous shifting in the hierarchy of design stages - almost full reversal of the process possible (regardless of individual methodology) - if needed of course; 6. Transformation of architecture itself. This concerns very deeply point 3 - and it rooms that natural consequences of the changes in perception, imagination and thinking should result in the new understanding of architecture - not as electronic methaphone, but as a sphere relevant (?!) to the vision of the world, which, as we see, is dramatically changing. The basic issue to accept is that this vision of the world should be interpreted individually. Personally.

title A Tool for Conceptual Design Evaluation Based on Compliance with Supplementary Planning Guidance and Local Planning Policies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are being designed in order to check design compliance with the requirements of local planning authorities; with regards to building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. The measures to determine proper evaluation will be based upon site-development briefs, and design guides produced by the local planning authorities. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. It will also provide many functions for editing two and three dimensional drawings specifically for the environmental analysis tasks. In addition to the common graphical output of Aut0CAD; i.e. plans, elevations and three dimensional models, the tool will generate textual analysis of the design in report format to use as part of the Environmental Impact Statement of proposed development. The speculative tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out tailor-made for architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of materials for environmental statements. Second, field observation will be carried out to observe the concerned professionals as decision-makers while assessing building design proposals. A prototype will be designed and then tested against the expectations of the tool designer, then the tool performance will be evaluated by a team of professionals participated in the field studies. A critical analysis of the prototype design methodology and the concluding study findings will be documented as part of a postgraduate research thesis to be completed in June 1995.

title StereoCAD: Three Dimensional Representation
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 343-355
summary Concepts of stereoscopic vision have been around for more than two thousand years. Despite this long history, its application to the field to architecture and design seems relatively unexplored. Synthesis of two technologies, the stereoscope and the computer, was the focus of the present study. The goal of the research was to determine if computer-generated stereoscopic pairs hold value for architectural design. Using readily available computer technology (Apple Macintosh) the research team modelled and rendered an existing project to verify the degree of correlation between the physical construct, the computer 3D model and resultant correlation between the physical construct, the computer 3D model and resultant rendered stereo-paired representation. The experiments performed in this study have shown that producing stereo-paired images that highly correlate to reality is possible using technology that is readily available in the marketplace. Both the technology required to produce (i.e., personal computer and modelling/rendering software) and view (i.e., modified stereoscope) the images is unimposing. Both devices can easily fit in a studio or a boardroom and together can be utilized effectively to permit designers, clients and end-users to experience proposed spaces and projects. Furthermore, these technologies are familiar (clients and end-users have already experienced them in other applications and settings) and assume a fraction of the cost of more dynamic, immersive virtual reality systems. Working from this base, limitations of the process as well as future applications of computer-generated stereoscopic images are identified.

title A New Methodology to Develop Hypermedia Systems for Architecture History
source Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 43-52
doi https://doi.org/10.52842/conf.ecaade.1995.043
summary This paper illustrates a research project concerning the analysis of architectural works through a comparative study based on hypermedia tools; by exploring the hypermedia, users can find the main subjects relative to the "method " of architectural planning. The use of multimedia in architecture allows the integration in a single system of different types of information which are necessary for the description of a work. texts, designs, photos and sounds. In addition, the hypertext information structure allows the direct intervention on analyzed projects, by pointing out the more important themes and their relationships. Users have the opportunity to immerse themselves in hypermedia and choose the subject to navigate through on each occasion. Our research project aims at developing a prototype concerning two architects. I.L.Kahn and F.L. Wright. The development methodology is based on the key role played by the components of architectonic works, thus allowing users to compare them in a simple and correct way. The methodology used in this work can be extended to other architects or periods, by simply changing the possibility of navigation, i.e. by changing the reading keys.

summary IPER (hypertext for the knowledge of building patrimony) is the result of a research developed with C.N.R. (National Research Institute). The aim of IPER is to provide the knowledge, the description and the management of one or more historical buildings for public or private institutions. IPER allowed us to improve our methodology of building analysis, covering various disciplinary fields, in two different systems. (1.) the first one, synthetic and suitable for a group of historical buildings, (2.) the second one, complex and particularly made for monumental buildings. // This experience is related to the new regulation of teaching architecture in Italy made in 1993. The main novelty is the introduction of the laboratories with the contemporary presence of two or three teachers of different disciplines, working together with the students on the same project with different approaches. This opportunity allowed us to introduce the "knowledge engineer" as a teacher in the laboratory of building technology. IPER is given to the students with the aim of experimenting and solving the theoretical and practical difficulties that students of different years may encounter in the knowledge and representation of buildings and in the organisation of all the data from the case study.

title On the Conceptual Feasibility of a CAAD-CAAI Integrated Decision Support System: A Computer Aided Environment for Technical Decision Making in Architecture
source Delft University of Technology
summary This document addresses two questions: What are the ultimate means of design support we can offer to the architect, and how can we devise them? We are not the first ones to address these questions, neither the first ones to point our finger in the direction of Decision Support Systems for such purposes. Nevertheless, we may be among those scholars that understanding 'Decision Support" in terms of "Learning Support", are willing to explore the implications that such an understanding assumes for the concept of Decision Support Systems. Our exploration in such regards has shown us that knowledge application and knowledge acquisition cycles describe a continuum, and that such cycles, encapsulated in our "Practice Based Learning" and "Continuing Professional Development" dynamics are present in both our instructional and professional environments. From such a perspective, our scope regarding feasible Decision Support Systems is not restricted to the use of CAAD instrumental resources, but expanded into a context of CAAD-CAAI integration. Throughout this document we conceive a system that blends CAAD and CAAI resources looking forward to the creation of a Support Environment that seeks to motivate a reflective attitude during design, in such a way, upgrade our capability for acquiring as well as applying knowledge in design. In instrumental terms, this document explains how mainstream CAAD developments in the field of "Intelligent Front End Technology" and CAAI developments in the field of "Knowledge-based Curricular Networks" can complement each other in the establishment of a Decision Support System of trans-environmental relevancy. As an application framework for the concept and instrumental base described above, this document presents an image of the kind of decision-making model that it will intend to support, the kind of task support model it will look forward to implement, and the kind of general instrumental layout it will require. On the basis of such an instrumental layout, the system that is hereby outlined can be regarded as a "CAAD-CAAI Integrated", "Intelligent", and "User-Oriented" Interface System.

summary In recent years two technologies, hypertext and expert systems, developed independently each other, drawn researcher´s attention since they seemed good tools to represent the knowledge and the reasoning process performed by human beings. These two technologies, until recently, had not too much intersection between them notwithstanding both were involved in representing the knowledge of experts of some domains and the domains itself. Also in the architecture field some expert systems and many hypertext products have been developed. Starting from some applications developed by our research team, in terms of expert systems and hypertext, we try here to give some suggestions about the possible interactions and the complementary use we may done of them.

source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 389-397
summary This paper reviews current 3D CAD building modelling by reference to a large ongoing case study, in which 3D building models and sites are used to generate coordinated drawing, schedule, and visualisation output. It focuses on barriers which current software interpose, preventing more complete use of 3D CAD to integrate building project information systems. Comparisons are made with tools and methodology developed in GIS, in which users make different selections as required from common databases, and it is argued that used in conjunction with 3D CAD building models, they could improve functionality and reduce barriers to effective deployment.

title An information engineering approach to modelling building design
source Automation in Construction 4 (1) (1995) pp. 5-15
summary This paper highlights potential problems in the construction industry concerning the large quantities of information produced and the lack of an adequate information structure within which to coordinate this information. The Information Engineering Method (IEM) and Information Engineering Facility (IEF) CASE tool are described and put forward as a means of establishing an information structure at a strategic level thus providing a framework for the implementation of lower level applications systems. The paper describes how the ICON (Integration/Information for Construction) project at Salford University is establishing and modelling the information requirements for the construction industry at the strategic level. The IEM and IEF are demonstrated using activity, data and interaction models with particular attention being paid to the function of building design within the broader context of design, procurement and the management of construction. Implications for future practice are also discussed.

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.

summary Teaching architecture is not primarily an instructional process but rather a process of interaction and experience. In this context multimedia material can be used to provide an active educational environment where students learn by doing. To yield an effective learning system expertise from various fields have to be combined. This paper emphasizes the technological challenges of multimedia applications in architectural design education. We discuss two research prototype systems and analyze the influence of the underpinning technology on the performance of the overall system design. Finally we give technical requirements that are demanded for next generation systems and propose a framework for concerted research action.

title Improving the legibility of virtual environments
source Second Euro graphics Workshop on Virtual Environments
summary Years of research into hyper-media systems have shown that finding one's way through large electronic information systems can be a difficult task. Our experiences with virtual reality suggest that users will also suffer from the commonly experienced "lost in hyperspace" problem when trying to navigate virtual environments. The goal of this paper is to propose and demonstrate a technique which is currently under development with the aim of overcoming this problem. Our approach is based upon the concept of legibility, adapted from the discipline of city planning. The legibility of an urban environment refers to the ease with which its inhabitants can develop a cognitive map over a period of time and so orientate themselves within it and navigate through it [Lynch60]. Research into this topic since the 1960s has argued that, by carefully designing key features of urban environments planners can significantly influence their legibility. We propose that these legibility features might be adapted and applied to the design of a wide variety of virtual environments and that, when combined with other navigational aids such as the trails, tours and signposts of the hyper-media world, might greatly enhance people's ability to navigate them. In particular, the primary role of legibility would be to help users to navigate more easily as a result of experiencing a world for some time (hence the idea of building a cognitive map). Thus, we would see our technique being of most benefit when applied to long term, persistent and slowly evolving virtual environments. Furthermore, we are particularly interested in the automatic application of legibility techniques to information visualisations as opposed to their relatively straight forward application to simulations of the real-word. Thus, a typical future application of our work might be in enhancing visualisations of large information systems such the World Wide Web. Section 2 of this paper summarises the concept of legibility as used in the domain of city planning and introduces some of the key features that have been adapted and applied in our work. Section 3 then describes in detail the set of algorithms and techniques which are being developed for the automatic creation or enhancement of these features within virtual data spaces. Next, section 4 presents two example applications based on two different kinds of virtual data space. Finally, section 5 presents some initial reflections on this work and discusses the next steps in its evolution.

title A Tool for Conceptual Design Evaluation Based on Compliance with Site-Development Briefs and Related Planning Regulations
source [eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi https://doi.org/10.52842/conf.ecaade.1993.x.c6i
summary The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are to check design compliance with the requirements of local planning authorities; characteristics evaluated will include building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. In addition to the common graphical output; i.c. plans, elevations and three dimensional models, it will generate textual analysis in report format to use as part of the Environmental Impact Analysis of proposed development. The tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out with architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of data for environmental statements. Second, field observation and participation will be carried out to observe decision-makers behaviour during assessment of building design proposals. A prototype is currently under development and will be tested against the expectations of the tool designer, Ashraf Ismail, and a team of professionals to be involved in the field studies. A critical analysis of the prototype design methodology and the study findings will be documented in the research thesis to be presented in June 1995.

title Visual Thinking For Architects And Designers: Visualizing Context In Design
source Van Nostrand Reinhold
summary Here at last is a book that will help architects and designers avoid the pitfall of creating buildings that battle aesthetically with everything within a three-block radius. In Visual Thinking for Architects and Designers, Ron Kasprisin and James Pettinari unveil a solution to designing for the complex urban landscape: visual thinking. A concept twenty-five years in the making, this integrative approach will help harried professionals prevent environmental disasters. The authors present three-dimensional drawing (visual thinking) as a communication and decision-making tool to be used during the design and planning process. Because architects, landscape architects, and urban designers often work independently, on different scales, and at different interludes, no one can truly envision the completed project. Visual thinking is a way of getting input from every member of the team. Here, you'll learn how to use graphics, whether hand-drawn or computer-generated, as a language to express complex systems, interrelationships, and environments. Using over 300 high quality drawings that are connected at many different scales; from aerial perspectives of entire regions to individual rooms and buildings-this groundbreaking book lays out an urban design process and methodology in a sequential and easily understood manner. The book is illustrated by the authors; own work, which has been recognized in national design competitions, and by the AIA, APA, and NEA. The authors masterfully cover the use of drawing to analyze and create spaces, drawing technique, and communicating complex information to the public. Case studies convincingly illustrate the authors; approach.

title LOST IN SPACE? ARCHITECTURAL PSYCHOLOGY - PAST, PRESENT, FUTURE
source Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary A methodological review by Kaminski (1995) summed up five perspectives in environmental psychology - patterns of spatial distribution, everyday “jigsaw puzzles”, functional everyday action systems, sociocultural change and evolution of competence. Architectural psychology (named so at the Strathclyde conference 1969; Canter, 1973) as psychology of built environments is one leg of environmental psychology, the second one being psychology of environmental protection. Architectural psychology has come of age and passed its 25th birthday. Thus, a triangulation of its position, especially in Central Europe, seems interesting and necessary. A recent survey mainly on university projects in German-speaking countries (Kruse & Trimpin, 1995) found a marked decrease of studies in psychology of built environments. 1994, 25% of all projects were reported in this category, which in 1975 had made up 40% (Kruse, 1975). Guenther, in an unpublished survey of BDP (association of professional German psychologists) members, encountered only a handful active in architectural psychology - mostly part-time, not full-time. 1996, Austria has two full-time university specialists. The discrepancy between the general interest displayed by planners and a still low institutionalization is noticeable.

How is the research situation? Using several standard research data banks, the author collected articles and book(chapter)s on architectural psychology in German- and English-language countries from 1990 to 1996. Studies on main architecture-psychology interface problems such as user needs, housing quality evaluations, participatory planning and spatial simulation / virtual reality did not outline an “old, settled” discipline, but rather the sketchy, random surface of a field “always starting anew”. E.g., discussions at the 1995 EAEA-Conference showed that several architectural simulation studies since 1973 caused no major impact on planner's opinions (Keul&Martens, 1996). “Re-inventions of the wheel” are caused by a lack of meetings (except this one!) and of interdisciplinary infrastructure in German-language countries (contrary to Sweden or the United States). Social pressures building up on architecture nowadays by inter-European competition, budget cuts and citizen activities for informed consent in most urban projects are a new challenge for planners to cooperate efficiently with social scientists. At Salzburg, the author currently manages the Corporate Design-process for the Chamber of Architecture, Division for Upper Austria and Salzburg. A “working group for architectural psychology” (Keul-Martens-Maderthaner) has been active since 1994.

title CAD Users Integration – A Current Problem
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 93-103
summary In just about every field of human activities, actions which cover the design processes and the development of "a product", demand the participation of people presenting different professions and specialization. Designers using CAD techniques, usually apply different programs and even computer systems. This means that quite a large number of different applications, realising various elementary tasks, may be used during architectural design process. Very seldom data generated by a single designer, may be used by another one presenting a different specialization and using a different program. As each one of them makes a lot of changes during the design process, the need for a free exchange of the computer generated data may be seen easily. Hitherto proposed solutions of the integration of CAD systems users may be qualified in two following groups: 1.) Those based on a single integrated CAD system; 2.) Those based on a neutral data transfer format.
