title	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title	Exploring the Possibilities of Conjoint Measurement as a Decision-Making Tool for Virtual Wayfinding Environments
doi	https://doi.org/10.52842/conf.caadria.1997.061

summary	Virtual reality systems may have a lot to offer in architecture and urban planning when visual and active environments may have a dramatic impact on individual preferences and choice behaviour. Conjoint analysis involves the use of designed hypothetical choice situations to measure individuals’ preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives, called product profiles, are generated and presented to respondents, who are requested to express their degree of preference for these profiles or choose between these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of production profiles. Virtual reality systems offer the potential of moving the response format beyond these traditional response modes. This paper describes a particular aspect of an ongoing research project which aims to develop a virtual reality based system for conjoint analysis. The principles underlying the system will be illustrated by a simple example of wayfinding in a virtual environment.

title	Edge of Chaos. Towards intelligent architecture through distributed control systems based on Cellular Automata.

summary	From the “Edge of Chaos”, a mathematical space discovered by computer scientist Christopher Langton (1997), compelling behaviors originate that exhibit both degrees of organization and instability creating a continuous dance between order and chaos. This paper presents a project intended to make this complex theory tangible through an interactive installation based on metamaterial research which demonstrates emergent behavior using Cellular Automata (CA) techniques, illustrated through sound, light and motion. We present a multi-sensory narrative approach that encourages playful exploration and contemplation on perhaps the biggest questions of how life could emerge from the disorder of the universe. We argue a way of creating intelligent architecture, not through classical Artificial Intelligence (AI), but rather through Artificial Life (ALife), embracing the aesthetic emergent possibilities that can spontaneously arise from this approach. In order to make these ideas of emergent life more tangible we present this paper in four integrated parts, namely: narrative, material, hardware and computation. The Edge of Chaos installation is an explicit realization of creating emergent systems and translating them into an architectural design. Our results demonstrate the effectiveness of a custom CA for maximizing aesthetic impact while minimizing the live time of architectural kinetic elements.

summary	The subject-matter of the contribution is presentation of the non-conventional didactical methods application in architectural education and research at the Faculty of Architecture of the Slovak Technical University in Bratislava. It is an application of a laboratorial method of architectural endoscopy based on a model urban space simulation principle and on the acquirement of an electrooptical visual display image information from a recording periscope unit interaction in the real time and the real model space, with the option of spontaneous semantic evaluation of the output on a video-monitor and of a synchronic timing process recording on a magnetoscope. Application of a consequential powerful PC-configuration with creative software enables further digital sequential processing both on the graphical output and for multimedial presentation.

title	High-end developments within the framework of dynamic-endoscopic viewing of models.
source	Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary	As far back as the seventies the first experiences with endoscopic viewing of models were made in the field of architecture and urban construction by introducing an endoscope into the model of the planned architectural and urban space. The monitor shows an approximation of real view of the new portion of building or city, resp. The endoscopic picture provides the viewer with the usual height of viewing and roughly the perspective of a pedestrian, whereas very often planning models of houses and city quarters are evaluated predominantly by means of the bird's eye view. Meanwhile, mechanical installations of relatively limited means have been installed at several university sites making for a simulation of spatial experience by means of endoscopic rides through a construction model such as from the view of a car driver. This paper presents a sketch for a research proposal which is aimed at anticipating high-end-developments based on the experience acquired so far using low-cost-simulations.

title	A history and application of visual simulation in which perceptual behaviour movement is measured.
source	Architectural and Urban Simulation Techniques in Research and Education [3rd EAEA-Conference Proceedings]
summary	For our research on perception and judgment, we have developed a new visual simulation system based on the previous system. Here, we report on the development history of our system and on the current research employing it. In 1975, the first visual simulation system was introduced, witch comprised a fiberscope and small-scale models. By manipulating the fiberscope's handles, the subject was able to view the models at eye level. When the pen-size CCD TV camera came out, we immediately embraced it, incorporating it into a computer controlled visual simulation system in 1988. It comprises four elements: operation input, drive control, model shooting, and presentation. This system was easy to operate, and the subject gained an omnidirectional, eye-level image as though walking through the model. In 1995, we began developing a new visual system. We wanted to relate the scale model image directly to perceptual behavior, to make natural background images, and to record human feelings in a non-verbal method. Restructuring the above four elements to meet our equirements and adding two more (background shooting and emotion spectrum analysis), we inally completed the new simulation system in 1996. We are employing this system in streetscape research. Using the emotion spectrum system, we are able to record brain waves. Quantifying the visual effects through these waves, we are analyzing the relation between visual effects and physical elements. Thus, we are presented with a new aspect to study: the relationship between brain waves and changes in the physical environment. We will be studying the relation of brain waves in our sequential analysis of the streetscape.

title	Generic representations : an approach for modelling procedural and declarative knowledge of building types in architectural design
source	Eindhoven University of Technology
summary	The building type is a knowledge structure that is recognised as an important element in the architectural design process. For an architect, the type provides information about norms, layout, appearance, etc. of the kind of building that is being designed. Questions that seem unresolved about (computational) approaches to building types are the relationship between the many kinds of instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called ‘prototypes’) face problems clarifying these questions. The research work at hand proposes to investigate the role of knowledge associated with building types in the design process.Knowledge of the building type must be represented during the design process. Therefore, it is necessary to find a representation which supports design decisions, supports the changes and transformations of the design during the design process, encompasses knowledge of the design task, and which relates to the way architects design. It is proposed in the research work that graphic representations can be used as a medium to encode knowledge of the building type. This is possible if they consistently encode the things they represent; if their knowledge content can be derived, and if they are versatile enough to support a design process of a building belonging to a type.A graphic representation consists of graphic entities such as vertices, lines, planes, shapes, symbols, etc. Establishing a graphic representation implies making design decisions with respect to these entities. Therefore it is necessary to identify the elements of the graphic representation that play a role in decision making. An approach based on the concept of ‘graphic units’ is developed. A graphic unit is a particular set of graphic entities that has some constant meaning. Examples are: zone, circulation scheme, axial system, and contour. Each graphic unit implies a particular kind of design decision (e.g. functional areas, system of circulation, spatial organisation, and layout of the building). By differentiating between appearance and meaning, it is possible to define the graphic unit relatively shape-independent.If a number of graphic representations have the same graphic units, they deal with the same kind of design decisions. Graphic representations that have such a specifically defined knowledge content are called ‘generic representations.’ An analysis of over 220 graphic representations in the literature on architecture results in 24 graphic units and 50 generic representations. For each generic representation the design decisions are identified. These decisions are informed by the nature of the design task at hand. If the design task is a building belonging to a building type, then knowledge of the building type is required. In a single generic representation knowledge of norms, rules, and principles associated with the building type are used. Therefore, a single generic representation encodes declarative knowledge of the building type. A sequence of generic representations encodes a series of design decisions which are informed by the design task. If the design task is a building type, then procedural knowledge of the building type is used.By means of the graphic unit and generic representation, it is possible to identify a number of relations that determine sequences of generic representations. These relations are: additional graphic units, themes of generic representations, and successive graphic units. Additional graphic units defines subsequent generic representations by adding a new graphic unit. Themes of generic representations defines groups of generic representations that deal with the same kind of design decisions. Successive graphic units defines preconditions for subsequent or previous generic representations. On the basis of themes it is possible to define six general sequences of generic representations. On the basis of additional and successive graphic units it is possible to define sequences of generic representations in themes. On the basis of these sequences, one particular sequence of 23 generic representations is defined.The particular sequence of generic representations structures the decision process of a building type. In order to test this assertion, the particular sequence is applied to the office building type. For each generic representation, it is possible to establish a graphic representation that follows the definition of the graphic units and to apply the required statements from the office building knowledge base. The application results in a sequence of graphic representations that particularises an office building design.Implementation of seven generic representations in a computer aided design system demonstrates the use of generic representations for design support. The set is large enough to provide additional weight to the conclusion that generic representations map declarative and procedural knowledge of the building type.

title	Generic Representations - Typical Design without the Use of Types
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 117-133
summary	The building type is a (knowledge) structure that is both recognised as a constitutive cognitive element of human thought and as a constitutive computational element in CAAD systems. Questions that seem unresolved up to now about computational approaches to building types are the relationship between the various instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed functional use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called 'prototypes') face problems clarifying these questions. It is proposed in this research not to focus on a definition of 'type,' but rather to investigate the role of knowledge connected to building types in the design process. The basic proposition is that the graphic representations used to represent the state of the design object throughout the design process can be used as a medium to encode knowledge of the building type. This proposition claims that graphic representations consistently encode the things they represent, that it is possible to derive the knowledge content of graphic representations, and that there is enough diversity within graphic representations to support a design process of a building belonging to a type. In order to substantiate these claims, it is necessary to analyse graphic representations. In the research work, an approach based on the notion of 'graphic units' is developed. The graphic unit is defined and the analysis of graphic representations on the basis of the graphic unit is demonstrated. This analysis brings forward the knowledge content of single graphic representations. Such knowledge content is declarative knowledge. The graphic unit also provides the means to articulate the transition from one graphic representation to another graphic representation. Such transitions encode procedural knowledge. The principles of a sequence of generic representations are discussed and it is demonstrated how a particular type - the office building type - is implemented in the theoretical work. Computational work on implementation part of a sequence of generic representations of the office building type is discussed. The paper ends with a summary and future work.

title	A National Strategy for CAAD and IT-Implementation in the Construction Industry the Construction Industry
doi	https://doi.org/10.52842/conf.ecaade.1997.x.o8u
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	The objective of this paper is to present a strategy for implementation of CAD and IT in the construction and building management#1 industry in Sweden. The interest is in how to make the best use of the limited resources in a small country or region, cooperating internationally and at the same time avoiding to be totally dominated by the great international actors in the market of information technology. In Sweden representatives from the construction and building management industry have put forward a research and development program called: "IT-Bygg#2 2002 - Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry. The presented strategy is based on a seminar with some of the most experienced researchers, developers and practitioners of CAD in Sweden. The activities were recorded and annotated, analyzed and put together afterwards. The proposal in brief is that object oriented distributed CAD is to be used in the long perspective. It will need to be based on international standards such as STEP and it will take at least another 5 years to get established. Meanwhile something temporary has to be used. Pragmatically a "de facto standard" on formats has to be accepted and implemented. To support new users of IT all software in use in the country will be analyzed, described and published for a national platform for IT-communication within the construction industry. Finally the question is discussed "How can architect schools then contribute to IT being implemented within the housing sector at a regional or national level?" Some ideas are presented: Creating the good example, better support for the customer, sharing the holistic concept of the project with all actors, taking part in an integrated education process and international collaboration like AVOCAAD and ECAADE.

summary	People regularly use non-physical, cognitive spaces to navigate and think. These spaces are important to architects in the design and planning of physical buildings. Cognitive spaces inform design - often underlying principles of architectural composition. They include zones of privacy, territory and the space of memory and visual thought. They let us to map our environment, model or plan projects, even imagine places like Heaven or Hell. Cyberspace is an electronic extension of this cognitive space. Designers of virtual environments already know the power these spaces have on the imagination. Computers are no longer just tools for projecting buildings. They change the very substance of design. Cyberspace is itself a subject for design. With computers architects can design space both for physical and non-physical media. A conscious integration of cognitive and physical space in architecture can affect construction and maintenance costs, and the impact on natural and urban environments. This paper is about the convergence of physical and electronic space and its potential effects on architecture. The first part of the paper will define cognitive space and its relationship to cyberspace. The second part will relate cyberspace to the production of architecture. Finally, a recent project done at the University of Michigan Graduate School of Architecture will illustrate the integration of physical and cyberspaces.

source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	It seems by now fairly accepted by many researchers in the field of the Computer Aided Design that the way to realise support tools for the architectural design is by means of the realisation of Intelligent Assistants. This kind of computer program, based on the Knowledge Engineering and machine learning, finds his power and effectiveness by the Knowledge Base on which it is based. Moreover, it appears evident that the modalities of dialogue among architects and operators in the field of building industry, are inadequate to support the exchange of information that the use of these tools requires. In fact, many efforts at international level are in progress to define tools in order to make easier the multiple exchange of information in different fields of building design. Concerning this point, protocol and ontology of structured information interchanges constitute the first steps in this sense, e.g. those under standardisation by ISO (STEP), PDT models and Esprit project ToCEE. To model these problems it has brought forth a new research field: the collaborative design one, an evolution of distributed work and concurrent design. The CAAD Laboratory of Dipartimento di Architettura and Urbanistica per l'Ingegneria has carried out a software prototype, KAAD, based on Knowledge Engineering in the fields of hospital building and of building for aged people. This software is composed by an Interface, a Knowledge Base, a Database and Constraints. The Knowledge Base has been codified by using the formal structure of frames, and has been implemented by the Lisp language. All the elements of KB are objects

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

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

title	Towards a Taxonomy of Virtual Reality User Interfaces
source	Proceedings of the International Conference on Information Visualisation (IV97), pp. 17-29
summary	Virtual reality based user interfaces (VRUIs) are expected to bring about a revolution in computing. VR can potentially communicate large amounts of data in an easily understandable format. VR looks very promising, but it is still a very new interface technology for which very little application oriented knowledge is available. As a basis for such a future VRUI design theory, a taxonomy of VRUIs is required. A general model of human computer communication is formulated. This model constitutes a frame for the integration of partial taxonomies of human computer interaction that are found in the literature. The whole model constitutes a general user interface taxonomy. The field of VRUIs is described and delimited with respect to this taxonomy.

summary	The present work is part of the exposition "Francesco Tamburini, La ConstrucciÛn del Espacio del Poder I", exhibited in Rivadavia Cultural Center ( Rosario city), and in Casa Rosada Museum during 1997. The Exposition is based on an investigation program of the space that involves Casa Rosada, determining this space as the first piece of its collection. In 1995, when a group of argentines where visiting the picture gallery Pianetti (Jesi, Italy) there have been found some watercolours of Francesco Tamburini (1846-1890), planner of the main faÁades of the Government and author of many works. These watercolours have great value for architecture, and unknown by public, they have been the starting point of the Exposition. Among these argentines was Roberto De Gregorio architect, historian teacher of this school of architecture, and in charge of the historical investigation. C.I.A.D.'s specific work consists in converting in digital data Casa Rosada's faÁades. The two first stages, already completed, finished on the digital data conversion of facades, in front of Plaza de Mayo and Rivadavia street, with presidential access esplanade. Actually the work is centred on the two facades left and on the elaboration of an electronic model for the edition of a CD-ROM containing the information of the exposition.

summary	This paper describes an innovative aspect of an ongoing research project to develop a virtual reality based conjoint analysis system. Conjoint analysis involves the use of designed hypothetical choice situations to measure subjects' preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Hypothetical alternatives, called product profiles, are generated and presented to subjects. A virtual reality presentation format has been used to represent these profiles. A profile consists of a virtual environment model and dynamic virtual objects representing the attributes with their respective levels. Conventional conjoint choice models are traditionally based on preference or choice data, not on dynamic decision making aspects. The status of this new approach will be described.

title	Concepts of Space in Computer Based Product Modelling and Design

summary	The everyday understanding of space may be self-evident and unproblematic. However, as soon as we are asked for a formal definition, e.g. in the context of building classification or product modelling, the concept of space is subject of controversy and misunderstanding. To some, space is the emptiness in which things are embedded, i.e. something immaterial. To others, space has no separate existence but is a property of the material world. Still, according to both views, space can be experienced. In this paper we analyse some influential work within building classification and building product modelling and criticise these for applying a concept of space without factual reference. We explore the ontological foundations for the concept of space, and conclude that space is an aspect view on things; depending on the view, it may be seen both as a property of things and as a thing in itself. Finally we show how construction space can be represented as an object in a conceptual schema for computer based space information.

title	Design and Modelling in a Computer Integrated Construction Process - The BAS-CAAD Project
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 501-518
summary	A new approach to product modelling in a design context is proposed. CAD-software must not only enable product modelling, but must also support product design. This is not fully achieved in the traditional 'enumerative' approach to product modelling. We discuss how product design and modelling can be based on a facetted' approach to information modelling, and how a data model that supports the design process can be based on a framework for system information. The background for our research is the current development in the construction industry towards a computer integrated construction process. A first prerequisite for this is the use of computer based models. Another prerequisite is that CAD-software can support the design of the results of the construction process, including construction works, user organisations, and the production and facility management processes. A third prerequisite is that computer based models are built with standardised concepts and terminology to enable exchange of information between different actors and computer systems during different stages of the construction process. Principles for organising frameworks for user organisation and construction works information are presented in an appendix.

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	The Groningen Experiment
source	Architectural Association Publications, publ. pend.
summary	In its first five years, the Architectural Association's Diploma unit II developed the theoretical framework of an alternative generative process, using computer models to compress evolutionary space and time. This led to a prototype that could be demonstrated interactively and the launch on the Internet of an experimental evolutionary environment which attracted global participation, established a dematerialised model. The new phase of the programme has begun to externalise this conceptual model into constructed form, focusing on urban-scale evolution and other historical and natural examples of co-operative and ecologically i integrated development. The approach has been to consider metabolic processes as a way of understanding both the formal development of urban symbiosis and the specific problem of materialization. The city planning department of Groningen commissioned a small working prototype demonstration of a predictive urban computer model. The unit produced an evolving model which explains the transition from the past to the present, and projects future trajectories a "what if" model for generating, exploring and evaluating alternatives. The model mediates in scale, space and time: ; in scale between the urban context and the fine grain of the housing typologies ; in space between the existing fabric of Groningen and specific dwelling units ; in time between the lifestyle within the medieval core and the desires of the citizens of tile next century
