title	Towards a dynamic evacuation system: developing methodologies to simulate the evacuation capabilities of subway stations in response to a terrorist attack with CBRNE weapons
doi	https://doi.org/10.52842/conf.ecaade.2014.1.109
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 109-118
summary	Events in recent times have highlighted the vulnerability of underground public transportation to possible terrorist attacks. A key question therefore is how an evacuation can be accomplished from underground stations safely. The strategy “go up and take the nearest exit to the surface” might not be the best response. Evidence from the Daegu subway station fire in 2003, investigated by Tsujimoto (2003) and Jeon and Hong (2009) establish that smoke or toxic airborne substances from a terrorist attack tend to use the same direct routes used by the fleeing passengers and as result significant injuries or fatalities can occur. This study proposes the concept of a dynamic evacuation system which would guide subway users along safe routes. To test how this system may operate, the study discussed combines measurements from tracer gas experiments with climate measurements to establish how toxic agents spread in subway stations under certain conditions and combines these results with those from pedestrian simulations applied to calculate evacuation times for possible escape routes. By integrating the resulting dataset from these methods, an evidence base of how a dynamic evacuation system may work can start to form.

doi	https://doi.org/10.52842/conf.ecaade.2003.369
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 369-372
summary	The research project in progress in the School of Architecture at the Izmir Institute of Technology includes documentation and reconstruction (by 3D modeling in electronic media) of damaged and lost early modern buildings in the Izmir region. The research aims to analyze the differences between Izmir modern buildings and Universal Modern Style, and preserve information on architectural heritage for future generations. The project is at the phase of developing an interactive web-based historical database (HizmO) that includes data (information, images, technical drawings, VRML models) and visualization of the findings. This database aims to be a pioneer in Mediterranean Region for exhibition of relations between traditional architecture (especially Mediterranean locality) and modernism, and organization of a network and off-campus learning activity for Mediterranean architecture that serve as a guide for students, researchers and architects. This paper aims at introducing this research and discussing the application of the database “HizmO,” its aims and potential effects on education in architectural history.

title	A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source	Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary	This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.

title	The Grammatical Studio Disrupting Regularities in Digital Media Design Education
doi	https://doi.org/10.52842/conf.caadria.2003.433

summary	Grammar governs the ordered way in which words are modified and combined in human languages to convey complex concepts beyond the simplicities of individual words. By extension (but less susceptible to analysis) grammar governs the way in which visual elements are modified and combined in art and design compositions. In this paper we focus on the outcomes and effects of placing grammar and contingency in the forefront of studio teaching with digital media in architecture and art, and how experience in these two domains can inform each other.

summary	Historically, the discipline of Architecture experiences time lags in its incorporation of novel philosophical ideas, technology, social ideas and so on, thanks to the inertia brought about by the building process of any built space. So, how has this concrete entrenched discipline taken on the business of Information Technology in this Information Age? In a 99% wired up 'Intelligent Island' with the national IT master plans created every 5-10 years, how has architectural practices adapted to these changes? What are the factors surrounding IT in architectural firms and how does this affect their adoption of IT. What role should architecture play in a 'Knowledge Economy'?

title	Erfahrungen und Erfolge bei der Umsetzung von RAPIS - Raum- und Projektinformationssystem für die Vienna Region [Experience and Results with the RAPS-System for the Viennese Region]
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	In shortest terms: RAPIS is a metadatabase on spatial information in the “Vienna Region”. More interesting then this simple fact is the way how theproject was implemented and what the effects on regional development are.RAPIS is the acronym for “Regional Planning and Project Information System for the Vienna Region” and was implemented as the Austrian part of the Interreg IIc Project IM-PLAN (Implementation of models for co-operative planning in metropolitan regions). The aim was to create aninformation platform for planning relevant information for the whole region, integrating existing data sources from federal and state administrationas well as private companies. RAPIS enables an overview of the available spatial datasets in the "Vienna Region " and focuses on the following questions: Which datasets relevant for planning and development are available within the region? Who can use these datasets under which conditions? Which plans and projects do exist for the region? In addition also metainformation on the most important international data sources was collected as well as information to projects and plans with regional and trans-regional impacts. During the implementation great importance was given to communication and sensitisation for the importance the topic: geo-informationinfrastructre as a key ressource for spatial development and regional co-operation. It showed up that Austria and the "Vienna Region" have a very good initial position and excellent databases on national, state, local and international level. However, it seems that almost everything exists already but hardly anybody knows about it ... – potential users do not know what data and information already exists and how to get and use it. Intensive communication, information and permanent discussion of the topic „(Geo-) Information“ within the „planners community“ carried the topic into the public and strengthened the consciousness for the importance of information-infrastructure for regional co-operation.

title	(Learning from Experience)? Promises, Problems and Side-effects of Case-Based Reasoning in Architectural Design
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	Learning from experience is the essence of Case-Based Reasoning (CBR). Because architects are said to learn design by experience, CBR seemed to hold great promises for their field, which inspired, in the 1990s, the development of various Case-Based Design (CBD) tools. Learning from the experience of developing and using these tools is the objective of this paper. On the one hand, the original expectations seem far from being accomplished today. Reasons for this limited success can be found at three different levels: the cognitive model underlying CBR, the implementation of this model into concrete CBD tools, and the context in which these tools are to be used. On the other hand, CBR research seems to have caused some interesting side effects, such as an increased interest in creativity and copyright, and a re-discovery of the key role that cases play in architectural design.

title	Light Pen - Sketching Light in 3D
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 327-338
summary	We describe a lighting design system driven by sketching on 3D virtual models. Conventional lighting design tools simulate the lighting effects of design decisions such as window locations, surface treatments, and fixture placement. Light Pen takes the inverse approach by allowing the designer to indicate desired illumination on a 3D model. This serves as input to a knowledge-based lighting design system, which recommends what lights to use and where to place them, based on the designer's expressed intentions and on the geometry of the space.

title	Perspective Vienna – A Comparison of Planning Scenarios and Real Development
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	With the suspension of national boarders in unions of nations, cities and their regions gain in significance for the economic, social and cultural development. This is particularly valid for Vienna, which lies close to the eastern boarder of the European Union, which should fall with the enlargement of EU in the near future. Of prominent importance is therefore to obtain a comprehensive understanding between proposed and defined aims for an urban development, the related measures and their extent ofimplementations and their actual or real effects. This paper attempts to give a strategic analysis of the Viennese urban and traffic development programs, from 1962, 1972, 1984 and 1994, on the one hand, and the data analysis of the statistical year books beginning from 1960 until 2000, on the other. The results show that adjustments have been made not only in response to certain trends, but also to a change of philosophy of urban development. It can be seen that certain assumptions of, for example, economic and transport measures can have the opposite outcome in relation to the intended objectives. Hence, one main question remains to beanswered: How should Vienna deal with the challenges ahead, to secure and foster a sustainable development under such circumstances on a long-term basis. In this respect, some measures are given, which should make it possible to overcome successfully these challenges.

summary	The publicly and privately funded national R&D program ‘Digital Construction’ was initiated in 2003 in order to establish a common platform for interchanging digital information and to stimulate digital integration in the Danish building industry. This paper explores the relation between visions, strategies and tools formulated in the ‘Digital Construction’ program, and the first experiences made from implementing the 3D work method part of the program in an ongoing building project. The discussions in the paper are placed in the complex field between choosing strategies for integrating information and communication technologies on national level, and the effects of these strategies on real life building projects.

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 217-224
summary	Work on a methodology that attempts to deliver a dynamic urban information system for visualising city in change is presented. We have developed a Multi-tier Extensible platform for Dynamic and Interactive Urban Modelling (MEDIUM) in connection with a large-scale historical urban study programme that investigates the history of the City of Sheffield. The MEDIUM platform shows some new properties that could address the limitations observed in conventional static urban modelling. We consider that 3D virtual city models can be created along a chronological axis and the time dimension of each model segment can be registered in such a way that the 3D models of different times can be brought together under a unifying visualisation platform. This will allow a visual understanding of how a city may have evolved to develop. To date, we have applied the MEDIUM platform to real city datasets and produced examples that allow us to examine what effects of urban visualisation could be achieved through the dynamic user-centred approach.

summary	Designers and design managers are interested in gaining a deeper understanding of the complexities of creativity and innovation (Langdon and Rothwell 1985). These two phenomena can be seen as complementary dimensions of a differentiation cycle where design plays a key value-adding role that gradually reduces through commoditisation. However, there is a lack of relevant evidence to explain the link between creativity and innovation. Creativity is increasingly considered as occurring in the interaction between the individual generator of an idea and a group of evaluators (Sawyer et al 2003). However, most studies have regarded the generation of a solution -and not its social impact- as the outcome of the creative process (Runco and Pritzker 1999). Accordingly, computational modelling of creativity has been mainly conducted in a social void (Boden 1999).

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 305-310
summary	Design problems are initially ill defined. A process of exploration, conceptualisation, development of alternative solutions and tests of the initial ideas is needed to find interesting and useful solutions. The urban context of a building site can provide hints, inspiration and constrains for various architectural design options. The design process can get the form of a constructive conversation between the designer and the applied design media if those media actively provide specifically needed tools and appropriate representations of the design and its urban context. This paper will report on a recently finished PhD research for design support systems that visualise the urban environment as a context for new architectural design. The main experiment focussed on the constructive conversation while the architect and the researcher 'wandered' through the digitally represented urban environment. In relation to the eCAADe theme of city-modelling, this short paper will especially focus on some of the findings and conclusions of the research and several recommendations regarding to city-modelling are provided.

title	Case Study of Tacit Knowledge Sharing in a Distributed Design Studio
doi	https://doi.org/10.52842/conf.acadia.2003.107
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 107-116
summary	This paper demonstrates the effects of experts’ tacit knowledge on improving architectural students’ design artifacts in a distributed design studio. In geographically distributed design environments, the Internet is an important medium by which architects can share tacit knowledge in the form of dialogue via online communication technologies, such as online chat and Instant Messaging (IM). In spring 2003, the National Aeronautics and Space Administration (NASA) and 8 schools conducted a collaborative design studio to develop a crew restraint system for space flights. Online chat software was used as a primary communication channel. Throughout the entire design studio, NASA professionals served as knowledge holders while undergraduate students participated as knowledge seekers. An interpretive content analysis and case study methodology were used in this study. We qualitatively observed the interactions between NASA and the students based upon two aspects: knowledge reflection and design improvement. Data were collected using document analysis of all knowledge sources and students’ design artifacts. The findings of this study indicate that the online chat system is useful in sharing tacit knowledge for the early part of design processes in a distributed design environment. Experts’ tacit knowledge appears to not only influence how students understand problems, but how they initiate conceptual design. This study provides empirical evidence regarding tacit knowledge sharing, and strengthens Schon’s (1983) claim about knowledge reflection in design studio. Furthermore, this study introduces architectural practitioners to the practical necessity of tacit knowledge sharing. This study is significant because its findings indicate the appropriate knowledge management strategy for architectural practitioners.

title	A NEW APPROACH TO VIRTUAL DESIGN FOR SPATIAL CONFIGURATION PROBLEMS,
source	7th IEEE International Information Visualisation Conference, London, UK, 16-17 July 2003. http://www.graphicslink.demon.co.uk/IV03/
summary	In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of Intelligent Virtual Environment, we propose an intelligent configuration system based on constraint logic programming (CLP), integrated in a real-time 3D graphic environment. This type of integration facilitates the expression of design knowledge in the VE and enables the user to interactively solve and/or refine a spatial configuration problem. In the system described in this paper, the user can visually explore configurations, but his interaction with objects of the configuration problem triggers new cycles of constraint propagation from the modified configuration to produce a new compatible solution.

summary	This paper applies the concept of fault tolerance to staircase layout plan. Fire or smoke may cause some staircases in a building inaccessible. We argue that architects should assess the result from the possible fault of vertical routes. The capability of tolerating staircase faults depends on space usage, arrangement, and pedestrian attributes. In this study, a mathematical model is constructed. For analysing pedestrian's movement in interior space, we employ Monte Carol simulation and Agent-Based Modelling method in a CAAD environment. It helps us to visualise the dynamic process of agent's evacuation process, and to test the problem of possible staircase faults. Finally, a case study brings some important discoveries.

summary	We speculate on a possible CAAD future that deploys and extends paradigms of natural growth and cellular development to an extent that would allow the planting and growth of man-made structures. This approach is based on the translation and expression of digital data structures into artificial physical form and the building of structures by decentral means. In such a scenario, generative and evolutionary architecture could seamlessly blend into building construction. As a discussion of as yet unavailable future technologies and methodologies the proposed remains at a “sketchy” level and must largely limit itself to preliminary and speculative considerations. In order to restrain the scope of this paper to the area of building design and construction, we focus on subway development and discuss possible cellular approaches to this particular field emphasizing aspects of functional aesthetics. We encourage the reader to take this example as a point of departure only, to generalise our explanations and to apply them to other building types. We support our discussion with findings made in software simulations of humandesigned cellular growth processes.

title	Physical Simulation in a VR Tool for Urban Design
doi	https://doi.org/10.52842/conf.acadia.2003.395
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 395-401
summary	Physical influences on a city, such as noise, light, air flow, and solar energy quantities, can already be simulated on computers; however, these simulations are usually not embedded into the urban planning process. Regarding a broad field of these influences and their correlations will improve the quality of the design. The use of simulations in the sketching stage provides the possibility of reacting accordingly for the urban planner, which is essential for sustainable design. This paper describes the development of a virtual reality tool for the early urban design process, in which we realized a network connection between a software package calculating noise propagation in urban spaces and a virtual reality design environment. In this dynamic VR design tool, it is possible to experiment with simple geometric forms and objects (these objects can be added to constructions, removed, and transformed). Interactively, with each action of the planner, simulations are generated and visualized in the VR environment in real-time. The last part of the paper describes our concept, how this VR design tool should be integrated in the study of urban planning, and how we want the students to get a sense for the impact of their design on physical phenomena in an urban scale.

summary	This paper describes the overall delivery of the Chaloem Ratchamongkhon Line, the first subway project in Bangkok as a challenging tunneling project in an urban environment. Eight pressure balance shields were employed under two major civil works contracts (North and South sections) to drive approximately 20 kilometers of twin-tunnel underneath congested area. As a international well known project, multinational workforces exca vated tunnels for the large subway system intended to carry a half million people daily over several lines through the central city in order to minimize traffic jam. Tunnel problem includes many existing structures along the tunnel route as well as flooding, ground subsidence, and fire problems.

title	Discussing Photon-Mapping and Radiosity-Based Rendering Algorithms to Evaluate Qualitative Lighting Design in Contemporary Architecture
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 351-360
summary	This paper attempts to determine the impact of different light propagation algorithm on visual perception of qualitative lighting design in contemporary architecture. Radiositybased and photon-mapping-based light simulation software is used in this empirical study as a “switch” to isolate the occurrence of the specific lighting phenomenon. Images generated by the two rendering software are graded using a subjective lighting metric. The results show varying visual response.
