summary	I am starting my presentation with some slides of architecture as a reminder that above all else we are involved in the education of future architects. Such is the enthusiasm of many of us for our specialist subject that computers dominate any discussion of architecture. We must not lose sight of the fact that we are using computers to assist in the manipulation of space, form, light, texture and colour, and in communicating our ideas. They should also be helping us and our students to understand and deal with the relationship of built form to its environment, its users and other buildings. The use of computers should not get in the way of this. In the final analysis the image on a computer screen is only that - an image, a representation of a building. It is not the building itself. It is a means to an end and not an end in itself. The image must not be a substitute for the physical building. We must remember that we use most of our other senses when experiencing a building and it is just as important to be able to touch, hear and smell a piece of architecture as well as being able to see it. Who knows, perhaps even taste is important. How much does the use of computers affect the design process and the final appearance of the building? Would these buildings have been substantially different if a system of working in three dimensions, similar to computer aided design, had been available to these architects. To what degree has the design process and method of working shaped the architecture of designers like Frank Lloyd Wright, Carlo Scarpa, Louis Sullivan, Charles Rennie Mackintosh or Alvar Aalto.

title	Methods to assist the design of road surfaces with a reservoir structure: To improve flood risk management
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Reservoir road surfaces can be seen as equipment of the future, in that they have two functions in the same structure (circulation and hydraulic functions). They can thus be laid without immobilising land, which is very expensive and prized in urban areas. Furthermore, they enable the limitation of the flow or volumes of running water, and thus help control rainwater, resulting in better flood risk management. The questions asked by drainage designers are how can we design these structures in the best way? How are they going to work for different types of rain (rain from storms, prolonged winter rain ....)? As for the public administrators, they wonder how a series of areas equipped with this type of technique (total flow management) would work. By solving this latter problem, we could really arouse interest in flood risk management. Given the diversity of structures possible for reservoir road surfaces (regulated, non-regulated, draining surface, dispersion surface...), we suggest comparing design and simulation methods, taking into account the measurement and total flow management problems mentioned above. So as to validate these comparisons and to give some directions concerning the use of one or the other methods, we use flow-metre measures on two different sites in Lyons. One of these sites is a car- park on a tertiary activity zone on the La Doua campus in Villeurbanne, the other a refuse dump in the Greater Lyons area in the town of Craponne. They are both interesting as they have different features. The first is non-regulated downstream and is used on a car-park for light motor-vehicles. The other is regulated and the traffic on it is made up of lorries. These sites will be described in this article.

title	The integral role of conventional sketching in conceptualisation
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Architectural Design Studies is an expanding research area, which recently has experienced dramatic shifts in approach. The successful application of computing to architectural practice has created pressure leading to a rediscovery of Architectural Drawing. The thrust of recent design studies is toward the early stages of the design process, where the modes of conception, human perceptual, and cognitive systems are the focus. In this paper we endeavour to examine the integral role of sketching in conceptualisation. A modelling technique relating to both the design and the graphic process 'sheds light' on the interaction between thought and drawing. Data from a protocol analysis is tested within the framework of the proposed model.

title	FULL-SCALE OR THE TRUTH IN “TRUE-SCALE”
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	Before architecture is put into reality it is simulated, either by means of drafts, or plans, models, or videos etc. .All these simulations represent anticipations of a later reality, instructions for action, sometimes they are no more than forecasts. Whether they hold true is up to the built object to prove. Only the full-scale throws light on spatial impact, the quality of design, the environmental compatibility, the value in use and finally, on the constructional accuracy regarding any decisions followed through with. The focus of working at the Department for Experimental Building Construction of the Graz University of technology is aimed at getting the students acquainted with these possibilities during their studies. Planning as well as building is carried out right on the spot and thus the process starting with the mere idea right down to the architectural reality, as well as the feedback, however in reverse, can be witnessed and perceived.

title	LIGHT AS LANGUAGE
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	With the unlimited supply of electric light our surroundings very easily may be illuminated too strongly. Too much light is unpleasant for our eyes, and a high level of light in many cases disturbs the conception of form. Just as in a forest, we need shadows, contrasts and variation when we compose with light. If we focus on the term compose, it is natural to conceive our environment as a wholeness. In fact, this is not only aesthetically important, it is true in a physical context. Inspired by old windows several similar examples have been built in the Trondheim Full-scale Laboratory where depth is obtained by constructing shelves on each side of the opening. When daylight is fading, indirect artificial light from above gradually lightens the window. The opening is perceived as a space of light both during the day and when it is dark outside. Another of the built examples at Trondheim University which will be presented, is a doctor's waitingroom. It is a case study of special interest because it often appears to be a neglected area. Let us start asking: What do we have in common when we are waiting to come in to a doctor? We are nervous and we feel sometimes miserable. Analysing the situation we understand the need for an interior that cares for our state of mind. The level of light is important in this situation. Light has to speak softly. Instead of the ordinary strong light in the middle of the ceiling, several spots are selected to lighten the small tables separating the seats. The separation is supposed to give a feeling of privacy. By the low row of reflected planes we experience an intimate and warming atmosphere in the room. A special place for children contributes to the total impression of calm. In this corner the inside of some shelves are lit by indirect light, an effect which puts emphasis on the small scale suitable for a child. And it also demonstrates the good results of variation. The light setting in this room shows how light is “caught” two different ways.

title	SPATIAL NAVIGATION IN VIRTUAL REALITY
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	For the past decade, we have carried out a number of participation projects using full-scale modeling as an aid for communication and design. We are currently participating in an interdisciplinary research project which aims to combine and compare various visualization methods and techniques, among others, full-scale modeling and virtual reality, in design processes with users. In this paper, we will discuss virtual reality as a design tool in light of previous experience with full-scale modeling and literature on cognitive psychology. We describe a minor explorative study, which was carried out to elucidate the answers to several crucial questions: Is realism in movement a condition for the perception of space or can it be achieved while moving through walls, floors and so forth? Does velocity of movement and reduced visual field have an impact on the perception of space? Are landmarks vital clues for spatial navigation and how do we reproduce them in virtual environments? Can “daylight“, color, material and texture facilitate navigation and are details, furnishings and people important objects of reference? How could contextual information clues, like views and surroundings, be added to facilitate orientation? Do we need our other senses to supplement the visual experience in virtual reality and what is the role of mental maps in spatial navigation?

title	Building a Synthetic Cognizer
source	Design Computation Cognition conference 2004, MIT
summary	Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title	ADELINE, an Integrated Approach to Lighting Simulation
source	Proceedings of Right Light 4, 4th European Conference on Energy-Efficient Lighting, pp.99-103
summary	The use of daylighting and artificial lighting simulation programs to calculate complex systems and models in the design practice often is impeded by the fact that the operation of these programs, especially the model input, is extremely complicated and time-consuming. Programs that are easier to use generally do not show the calculation capabilities required in practice. A second obstacle arises as the lighting calculations often do not allow any statements regarding the interactions with the energetic and thermal building performance. Both problems are mainly due to a lacking integration of the design tools of other building design practitioners as well as due to insufficient user interfaces. The program package ADELINE (Advanced Daylight and Electric Lighting Integrated New Environment) being available since May 1996 as completely revised version 2.0 presents a promising approach to solve these problems. This contribution describes the approaches and methods used within the international project IEA Task 21 for a further development of the ADELINE system. Aim of this work is a further improvement of user interfaces based on the inclusion of new dialogs and on a portation of the program system from MS-DOS to the Windows NT platform. Additional focus is laid on the use of recent developments in the field of information technology and experiences gained in other projects on integrated building design systems, like for example EU-COMBINE, in a pragmatical way. An integrated building design system with open standardized interfaces is to be achieved inter alia by using ISOSTEP formats, database technologies and a consequent, object-oriented design.

title	Awareness Space in Distributed Social Networks
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
summary	In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.

title	Creativity and HyperMedia, MultiMedia, the InterNET an Virtuality
source	CAD Creativeness [Conference Proceedings / ISBN 83-905377-0-2] Bialystock (Poland), 25-27 April 1996 pp. 99-115
summary	Creativity is defined in an operational manner as being associated with the new, and hence with surprise and variety. Certain qualities of various computer media (HyperMedia, Multimedia, InterNET and Virtuality) are considered in the light of this definition in order to determine how they might be shaped and used to enhance (the likelihood of) creativity, particularly in architectural design. A more thorough examination of the qualities of computational media is suggested. together with a method for carrying this out. A major consideration of CAD has been excluded since the author has, elsewhere, recently covered this aspect of computing in some depth.

title	EFFECTIVENESS OF MODELS
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	Architects use many types of models to simulate space either in their design process or as final specifications for building them. These models have been proved useful or effective for specific purposes. This paper evaluates architectural models in terms of five effectiveness components: time of development, cost, complexity, variables simulated and ecological validity. This series of models, used regularly in architecture, are analysed to finally produce a matrix that shows the effectiveness of the different models for specific purposes in architectural design, research and education. Special emphasis is given to three specific models: 1/10 scale, full-scale and computer generated.

title	No More Fear or Doubt: Electronic Architecture in Architectural Education
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	Operating electronic and Internet worked tools for Architectural education is an important, and merely a prerequisite step toward creating powerful tele-collabortion and tele-research in our Architectural studios. The design studio, as physical place and pedagogical method, is the core of architectural education. The Carnegie Endowment report on architectural education, published in 1996, identified a comparably central role for studios in schools today. Advances in CAD and visualization, combined with technologies to communicate images, data, and “live” action, now enable virtual dimensions of studio experience. Students no longer need to gather at the same time and place to tackle the same design problem. Critics can comment over the network or by e-mail, and distinguished jurors can make virtual visits without being in the same room as the pin-up—if there is a pin-up (or a room). Virtual design studios (VDS) have the potential to support collaboration over competition, diversify student experiences, and redistribute the intellectual resources of architectural education across geographic and socioeconomic divisions. The challenge is to predict whether VDS will isolate students from a sense of place and materiality, or if it will provide future architects the tools to reconcile communication environments and physical space.

title	Generic Representations and the Generic Grid: Knowledge Interface, Organisation and Support of the (early) Design Process
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Computer Aided Design requires the implementation of architectural issues in order to support the architectural design process. These issues consist of elements, knowledge structures, and design processes that are typical for architectural design. The paper introduces two concepts that aim to define and model some of such architectural issues: building types and design processes. The first concept, the Generic grid, will be shown to structure the description of designs, provide a form-based hierarchical decomposition of design elements, and to provide conditions to accommodate concurrent design processes. The second concept, the Generic representation, models generic and typological knowledge of building types through the use of graphic representations with specific knowledge contents. The paper discusses both concepts and will show the potential of implementing Generic representations on the basis of the Generic grid in CAAD systems.

summary	During the spring term 1996, 13 students of the 3rd and 4th year at the School of Architecture at Lund University had the opportunity to make a one semester CAAD project. 11 students chose the individual exercise to use computer media for developing a small architectural design in interaction with a client. The focus was set more on visualization and the process of communicating ideas, feelings and practical solutions between architect and client and visa versa rather than concentrated on the final product. This paper describes the process of the project and the reflections of the participants. It will discuss problems from the teachers point of view.

doi	https://doi.org/10.52842/conf.ecaade.1996.051
summary	We often speak of changes in design process due to an application of computers. But in my opinion we more often rather speak of lack of changes. Lets hope that some day we will be able to witness full integrity and compatibility of design process and tools applied in it. Quite possible such an integrity may occur in the cyberspace. Nevertheless before that could happen some changes within the teaching methods at faculties of architecture, where despite great numbers of computer equipment used, the students are still being taught as in the XIX century. In terms of achieved results it proves ineffective because application of chalk and blackboard only will always loose to new media, which allow visual perception of dinosaurs in Jurassic Park. Our civilisation is the iconographic one. And that is why teaching methods are about to change. An application of computer as simply a slide projector seems to be way too expensive. New media demands new process and new process demands new media. Lets hope that could be achieved in cyberspace as being a combination of: classic ways of teaching, hypertext, multimedia, virtual reality and a new teaching methodology (as used in Berlitz English School - full brainwash). At our faculty several years ago we experimentally undertook and applied an Integrated Design Teaching Method. A student during design process of an object simultaneously learnt all aspects and functions of the object being designing i.e.: its structure, piping and wiring, material cost and even historic evolution of its form and function. Unfortunately that concept was too extravagant as for the seventies in our reality. At present due to wide implementation of new media and tools in design process we come to consider reimplementation of IDTM again.

summary	The experiences illustrated here are related to the new regulation of teaching architecture in Italy and these ones in particular have been concentrated on the technological aspects of teaching architecture. We can consider the evolution of the architect from the individual operator to the manager multi- disciplinary aspects of the building process ( building process manager) as a reality today. Information technology, specifically applied to bio-climatic architecture and environmental control, can be of great importance for this professional role, and for this reason it is very useful to include these topics at the beginning the teaching design process. This paper describes a particular approach to bio-climatic problems of the architectural project. An experimental course has been performed by the second year students of the "Laboratorio di Construzione dell' Architettura", at the School of Architecture of the Second University of Naples, in Aversa. Analysing old and new buildings, they used some flow charts for the evaluation and representation of energetic behaviour of buildings regarding their climatic and geographical environment. In the flow charts the decisions are represented by boxes that allow to determine "rightness index" related to: morphological characters of the site and environment, typology and particular organisation of the inside spaces, shape of building, technological solution of the building "skin". The navigation through the decision boxes is made with simple options like; "winds: protected or exposed site", "shape of building; free, close or cross plane", "presence of trees on the south,; yes or not",; it shows the students the bio-climatic quality of the building and, through numeric value assigned to each option, determines the "weight" of its climatic comfort.

summary	The development of the World Wide Web into an active, visual social environment poses unique opportunities for the design professions. Multi-user Domains, social meeting places in cyberspace, are mostly text-based virtual realities which use spatial references to set the stage for social interaction. Over the past year design students at the New Jersey Institute of Technology School of Architecture have investigated several text-based domains. In the course of their work, they envisioned and graphically portrayed these environments as immersive virtual realities through the use of computer animation. Their studies addressed issues ranging from the nature of symbolic motion to social/political structures of these domains.

title	An optimization method of the facility location by genetic algorithm
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	In planning of community-facilities, it is important to decide the facility location to provide the effective service for residents. The behavior of residents using the facility and the evaluation methods of the location have been studied. But, finding the optimum location is very hard in actual planning because the volume of calculation depends on the number of feasible locating points of facilities. To conquer the difficulty of searching the optimum location, we propose an optimization method using Genetic Algorithm. An alternative of location is expressed by a chromosome. Each chromosome consists of genes, and each gene expresses a located zone of the facility. We gave definitions of genetic procedures; crossing-over, mutation and selection. Alternatives of the facility location are generated by these genetic procedures like as life evolution. For each alternative, the behaviors of users are estimated by a spatial-interaction model, and the facilities that residents in each place choose are determined. The effectiveness of the location is measured by a total sum of distances between the facility and the user. After the confirmation of the effectiveness of our method by applying on ideal example problems, we applied it on the actual problem in Japanese town. By this method we could find the optimum location in about one-third time and effort as compared with the ordinal method.
