summary Some applications of hypermedia technology we developed trough the years to represent urban environment are reviewed. From the results the need for a change of paradigm rises. The strategy for a new system to develop is exposed, based on the assumption that: – the information does not pre-exist its representation; -– the process of cooperatively and competitively represent a situation causes its changing in the same time. -– no single actor will be able to represent the territory in its complexity; The question we need to answer is not what kind of technology we need to manage the information we have but the opposite: what kind of information we need for the technology we have. This information is not neutral nor automatically generalisable, thus, to implement a content based approach, a new system will be designed during a urban developing project.

title Using a Spatial Microsimulation Decision Support System for Policy Scenario Analysis
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 177-191
summary This paper discusses the potential of a spatial microsimulation-based decision support system for policy analysis. The system can be used to describe current conditions and issues in neighbourhoods, predict future trends in the composition and health of neighbourhoods and conduct modelling and predictive analysis to measure the likely impact of policy interventions at the local level. A large dynamic spatial micro-simulation model is being constructed for the population of Leeds (approximately 715,000 individuals) based on spatial microsimulation techniques in conjunction with a range of data, including 2001 Census data for Output Areas and sample data from the British Household Panel Survey. The project has three main aims as follows: (i) to develop a static microsimulation model to describe current conditions in Leeds; (ii) to enable the performance of ‘What if?’ analysis on a range of policy scenarios; and (iii) to develop a dynamic microsimulation model to predict future conditions in Leeds under different policy scenarios. The paper reports progress in meeting the above aims and outlines the associated difficulties and data issues. One of the significant advantages of the spatial microsimulation approach adopted by this project is that it enables the user to query any combination of variables that is deemed desirable for policy analysis. The paper will illustrate the software tool being developed in the context of this project that is capable of carrying out queries of this type and of mapping their results. The decision support tool is being developed to support policy-makers concerned with urban regeneration and neighbourhood renewal.

title Information Rich 3D Computer Modeling of Urban Environments
source Working Paper 35, Centre for Advanced Spatial Analysis Working Papers; London, August 2001
summary We are living in an increasingly information rich society. Geographical Information Systems now allow us to precisely tag information to specific features, objects and locations. The Internet is enabling much of this information to be accessed by a whole spectrum of users. At CASA we are attempting to push this technology towards a three-dimensional GIS, that works across the Internet and can represent significant chunks of a large city. We believe that the range of possible uses for such technology is diverse, although we feel that urban planning is an area that can benefit greatly. An opportunity to push this ìplanning technologyî arose when CASA won a tender from Hackney Council to develop a dynamic website for community participation in the process of regenerating the Woodberry Down Estate. This is a run down part of northeast London that is undergoing a major redevelopment. CASA has developed a system that not only informs the local residents about the redevelopment process but it also enables them to use dynamic visualisations of the ìbefore and after effectsî of different plans, and then to discuss and vote on the variety of options.

title Realism vs. Reality in Digital Reconstruction of Cities
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The digital reconstruction of existing cities using virtual reality techniques is being increasingly used. For consultants, municipalities and planning departments these models provide decision support through visual simulations (El Araby, 2001). For academia they provide a new tool for teaching students urban design and planning (Okeil, 2001). For authorities they provide a tool for promoting the city on the world wide web trying to attract more businesses and tourists to it. The built environment is very rich in detail. It does not only consist of open spaces surrounded by abstract buildings but it also includes many smaller objects such as street furniture, traffic signs, street lights, different types of vegetation and shop signs for example. All surfaces in the built environment have unique properties describing color, texture and opacity. The built environmentis dynamic and our perception is affected by factors such as pedestrian movement, traffic, environmental factors such as wind, noise and shadows. The built environment is also shaped by the accumulation of changes caused by many influences through time. All these factors make the reconstruction of the built environment a very complex task. This paper tries to answer the question: how realistic the reconstructed models of urban areas can be. It sees “Realism“ as a variable floating between three types of realties. The reality of the physical environment which we are trying to represent. The reality of the digital environment which will host the digitally reconstructed city. And the reality of the working environment which deals with the problem of limitation of resources needed to digitally reconstruct the city. A case study of building a 3D computer model of an urban area in the United Arab Emirates demonstrates that new time-saving techniques for data acquisition can enhance realism by meetingbudget limitations and time limitations.

title Are European cities becoming similar?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The paper discusses city specific development patterns to overcome todays transport problems. The results are based on recent andongoing research activities at TUW-IVV and ITS. At previous CORP-conferences, we presented the basics and the development of aplanning support tool to find optimal policy packages in urban transport and land use (Emberger, 1998), (Pfaffenbichler, Emberger, 2001). The core of this planning support tool is a dynamic land use and transport interaction model. This model, which we refer to as Sketch Planning Model (SPM), is embedded into an appraisal and optimisation framework. The SPM and this framework were developed in the recently finished European Union funded research project PROSPECTS1. Case studies with this planning supporttool were performed within PROSPECTS for the cities Edinburgh, Helsinki, Madrid, Oslo, Stockholm and Vienna. These cities are principally comparable in regards of their status (capitals and major business and education centres), but different in their size, population density, transport system etc. A set of policy instruments like public transport improvements, car traffic restrictions, and infrastructure provision was available to formulate strategies to reduce negative impacts of transport and to increase welfare. The overall objective was a sustainable development of the city. Although the instruments and the goals are similar in all investigatedcites, different solutions were adequate. The solutions vary in regard of spatial implementation, implementation time and level of implementation. The paper will highlight some reasons for the different development paths of the cities. As well the comparison of the do nothing scenario as the comparison of the most feasible policy strategies shows that European cities are different, need different solutions for their problems and will stay different in the future.

title Strategy on applying computational fluid dynamic for building performance evaluation
source Automation in Construction 10 (3) (2001) pp. 327-335
summary Predicting and evaluating building performance plays an important role in the training of responsible architects. Building performance includes issues such as: structural stability, acoustic quality, natural lighting, thermal comfort, and ventilation and indoor air quality. These types of analyses are often laborious, non-intuitive, and non-graphical. As a result, these important issues do not arouse the enthusiasm of architecture students or building professionals. The Chinese University of Hong Kong (CUHK) research team proposes to explore and develop a long-term strategy to apply scientific visualization on teaching and research in environmental technology and building performance. This paper presents the development process and results of research projects for applying computational fluid dynamics (CFD) on building performance evaluation. CFD On-line Teaching project's aim is to develop a web-based training course for architecture students to apply CFD simulation on design problem solving. Each lesson not only illustrates basic principles regarding airflow in the building design, it also contains CFD sample files with predefined flow cells for students to test different concepts. GiLin Temple project's aim is to apply CFD simulation on investigating the wind resistance of Tong Dynasty heavy timber structure. Airflow information generated in the project includes the visual representation of the pressure distribution and velocity field on all slices through the temple, and the tracking of particles as they flow around or through a building. The China housing residential airduct study focuses on simulating the indoor airflow regarding the airduct design of China Experimental Urban Housing Scheme. The visual representation of the pressure distribution and velocity field in the airducts provides vital information for helping China Housing Research Center improve the current design.

summary This study introduces a methodology for the evaluation, among a set of possible plans and/or policies, of a transport system which could reduce the effects of the network congestion on an urban area. Hence it is proposed a procedure which contains a new element compared with the current methodologies that is the final user’s evaluation of the examined system by turning to the application of the contingent valuation method, a technique like stated preferences. The approach we propose is based on the necessity for a determination of an optimal solution to the urban congestion to be established on the politic acceptability by the final user. Solutions which result virtually feasible for a public administration both on a technique and economic point of view often meet hostility by individuals. Consequently, it would be interesting for policy makers to adopt a process of valuation which could let to understand the user’s sensitivity and hostility towards specific configurations of the system, chosen as solution to decongestion (traffic calming, roadpricing, auto-free zones) and consequently to make less unpleasant the strategy to be carried out to control congestion (Harrington et al., 2001). In this way, a user does not judge the implementation of a set of projects made by a decision-maker as imposition and he is willing to pay in order to fulfil the chosen scenario. Finally we describe an application of the proposed methodology relating the definition of the integrated transport system in the metropolitan area of Bari, chief town of Apulia.

title Computer-aided design decision support: interfacing knowledge and information
source Automation in Construction 10 (2) (2001) pp. 203-215
summary Computer-aided design decision support has proved to be an elusive and intangible project for many researchers as they seek to encapsulate information and knowledge-based systems as useful multifunctional data structures. Definitions of `knowledge', `information', `facts', and `data' become semantic footballs in the struggle to identify what designers actually do, and what level of support would suit them best, and how that support might be offered. The Construction Primer is a database-drivable interactive multimedia environment that provides readily updated access to many levels of information aimed to suit students and practitioners alike. This is hardly a novelty in itself. The innovative interface and metadata structures, however, combine with the willingness of national building control legislators, standards authorities, materials producers, building research organisations, and specification services to make the Construction Primer a versatile design decision support vehicle. It is both compatible with most working methodologies while remaining reasonably future-proof. This paper describes the structure of the project and highlights the importance of sound planning and strict adhesion to library-standard metadata protocols as a means to avoid the support becoming too specific or too paradigmatic.

title Interactive Storytelling and Its Role in the Design Process
doi https://doi.org/10.52842/conf.caadria.2002.151
source CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 151-158
summary Projects of ever increasing complexity and size have incited the need for new and robust design methodologies and tools in an effort to manage complexity, lower costs, ascertain quality and reduce risk. Technology convergence through the growing availability of networked computers, rapid progress in Computer Aided Design (CAD) and information management have encouraged the undertaking of even more complex designs that demand high degrees of interaction, collaboration and the efficient sharing and dissemination of information. It is suggested that interactive storytelling and interactive design (Rafi and Karboulonis, 2001) techniques that use non-linear information mapping systems can be deployed to assist users as they navigate information that is structured to address localized needs as they arise. The design process is a collaborative effort that encompasses diverse knowledge disciplines and demands the management and utilization of available resources to satisfy the needs of a single or set of goals. It is thought that building industry specialists should work close together in an organised manner to solve design problems as they emerge and find alternatives when designs fall short. The design process involves the processing of dynamic and complex information, that can be anything from the amount of soil required to level lands - to the needs of specific lightings systems in operation theatres. Other important factors that affect the design process are related to costs and deadlines. This paper will demonstrate some of our early findings in several experiments to establish nonlinear storytelling. It will conclude with a recommendation for a plausible design of such a system based on experimental work that is currently being conducted and is reaching its final stages. The paper will lay the foundations of a possible path to implementation based on the concept of multi-path animation that is appropriate for structuring the design process as used in the building industry.

title Evolutionary Automata for Suburban Form Simulation
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 767-780
summary The paper outlines a research project to develop a dynamic simulation of suburbanization processes. The approach to simulating suburban form relies on modelling different interacting processes on various scales. Two layered models are implemented, the Socio-Economic and Zoning model and the Suburban Form model, respectively by means of cellular automata and genetic programming. The Socio-Economic and Zoning model simulates exogenous factors and endogenous processes of large-scale suburban dynamics. The model approximates the area by means of a rectangular grid to the scale of hundred meters. The Suburban Form model uses a smaller grid, to the scale of meters, and is three-dimensional. The resulting dynamic, 3D, fine-scale model will create scenarios of suburban growth, allowing evaluation of their consequences on built environment and landscape.

title Development of a virtually real construction site - design for safety
source CIDAC, Volume 3 Issue 2 May 2001
summary Interpreting two-dimensional drawings presents problems for builders since they are required to transfer these into three-dimensional mental images. Virtual Reality (VR) technology has several advantages. One is that it can be used to solve the problem of image transfer since VR supports a What-You-See-Is-What-You-Get object together with a binocular effect, improving users' visual sense. Another advantage of VR is the capability to present a real time dynamic simulation, which can be used to represent construction processes. By representing virtually real construction components and processes, users can walk through the virtual project. Using his/her safety knowledge, he/she can identify safety hazards inherent within the virtually real construction components and processes and determine the appropriate safety precautions to employ to make the virtual construction site safe.

This hazard identification process can be better achieved if a guideline is provided. Therefore, a Design-For-Safety-Process (DFSP) guideline is developed to assist users to identify safety hazards as well as to recommend remedial safety measures. This paper discusses how virtual reality benefits the construction industry in terms of a design representation. In addition, important issues in developing virtually real construction components and processes as well as functions of virtual reality which are needed to support the DFSP are discussed.

title Relation-Based Groupware For Heterogeneous Design Teams
doi https://doi.org/10.52842/conf.ecaade.2001.086
source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 86-91
summary This paper describes a work about coordination of concurrent engineering in the building construction and design. More particularly it describes the coordination of project teams which are heterogeneous and short-lived. The French context of the building trade is at present characterized by an increase of the quality requirements and by a reduction of the conception and realization delays. This induces the building sector to look for new modes of cooperation as they already exist in industry and services. With a few exceptions, the concurrent engineering tools taken from these sectors are not used in building projects. We make the assumption that the lack of use of these tools is due to the non-fitting of the common existing tools to the specificities of our sector. The solution we propose give a relational vision of the cooperation and the interactions existing during the processes of conception-construction in architectural works. Our first interest point concerns the representation of the actors, the documents and the assignments as a relational network and not as a hierarchical tree, mostly used in the groupware tools. In a second point, we use this relational network to produce a graphic and dynamic representation of the projects. The goal of this method is to reinforce the co-operation and the group awareness by supplying to the actors a good vision of the project evolution in order to increase the conception quality.

title A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 685-700.
summary Architects—like other designers—tend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses—in the way architecture is conceived, taught and critiqued—results in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as “movement”, “guiding” and/or “rest” plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

title Route analysis in complex buildings
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 711-724
summary Analysis of pedestrian circulation in buildings is usually performed in the early stages of the design process or later on with respect to a specific design problem such as fire safety. In both cases, the analysis relates more to wayfinding, i.e. search for a route on the basis of fundamental normative criteria. Wayfinding analysis in existing buildings is useful for the comparison between “rational” behaviour and actual usage but this comparison does little to explicate the observed structure of pedestrian circulation. In contrast to wayfinding, route analysis deals with the registration and assessment of actual patterns of pedestrian circulation in existing buildings. These patterns are represented topologically and geometrically. The geometric representation makes use of norms underlying building codes in order to reach an appropriate level of abstraction. Route representations are implemented on top of a building representation of relevant spatial and building elements. The building representation serves both as input and output for the route analysis. Input and output are largely automated, including production of the geometric route locally (i.e. within each space) and measurement of route distance and complexity. Use data are collected in an alphanumeric database and linked dynamically to the geometric and topological representation. Route analysis supports and refines other forms of post-occupancy evaluation by adding important dynamic aspects to activity allocation and compartmentalization.

summary This paper documents an initial study investigating the integration of Computational Fluid Dynamics (CFD) simulation modeling into wind mitigation design for building structures located in wind hazard prone areas. Some of the basic principles and theoretical concepts of fluid flow and wind pressure as well as their translation into design criteria for structural analysis and design are reviewed, followed by a discussion of a CFD application case study for a simulated hurricane force wind flow over a low rectangular building using the k-epsilon turbulence model. The techniques and parameters for development of the simulation are discussed and some preliminary interpretations of the results are evaluated by comparing its predictions against existing experimental and analytical data, with special attention paid to the American Society of Civil Engineers, Minimum Design Loads for Buildings and Other Structures, ACSE 7-98 and the Uniform Building Code .

title Distributed Representation of an Architectural Model
source Harvard University
summary This thesis proposes a new strategy for design representation that uses dynamically decentralized design objects, distributed over the web and instantiated just-in-time, instead of the traditional centralized, static and local CAD model. It addresses the problem of coping with dynamic information changes that architects face when designing with increasingly time-sensitive product information from multiple suppliers. The dissertation describes the new distributed architecture for design representation, and outlines a corresponding new process model to address the needs of AEC (Architectural, Engineering and Construction) industries' architectural designers during design and procurement phases. The feasibility of the process was tested in a prototype system that combines existing state-of-the-art technologies. The prototype integrates the direct manipulation functionality of Autodesk's i-Drop technology with the Internet communication protocols HTTP and TCP/IP, and a VBA macro running from within AutoCAD 2000i. In the proposed model, libraries of AEC objects, representing suppliers' products, are located in multiple suppliers' databases and are made available to CAD designers remotely over the Web. Suppliers using the system are expected to produce product information as XML documents. This standardizes the interface with the remote designers.

source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 89-102
summary This paper presents our current development of the Sheffield Urban Contextual Databank (SUCoD) prototype that provides users with a Webbased interface for dynamic retrieval of architectural and urban contextual information of the city of Sheffield. In comparison with past attempts of building Virtual Cities accessible over the Internet, we have experimented with a different system architecture capable of generating VRML models and other related documents on the fly according to users' requests. Through working examples, we describe our methods of implementing the data communications between Java applets and Common Gateway Interface (CGI) scripts. The SUCoD prototype has been developed to explore and demonstrate how user centred dynamic retrieval of urban contextual information can be supported, which we consider a user requirement of primary importance in its future use for collaborative design and research relating to the city of Sheffield.

summary Cities are growing out of control and with unforeseen complexity, with a lavish energy waste and an increasing life-quality loss. A possible approach to cope with these difficulties is the use of Urban Dynamic Analysis, a multidisciplinary body of knowledge allowing the holistic study of time-relationships between city structures and their related distinctive functions. A set of computer-aided tools is being developed following these guidelines. They are intended for the assessment of the behaviour of morphological layouts as regards to energy saving. Three such tools are described, using different pixel-counting approaches in order to simplify and facilitate their use.

title Mouse.class: Experiments for Exploring Dynamic Behaviors in Urban Places
source University of Washington, Design Machine Group
summary Urban space comprises not only physical forms - buildings, streets, plazas, trees, etc. – but also the people 'acting on them'. The purpose of this thesis is to increase our awareness of behavior and environment relationships, focusing on local movement at the individual level in a pedestrian environment. The thesis describes the experiment Mouse.class, as a concept demonstration model, which allows users to create a 2D-virtual environment for accommodating autonomous agents, Mouse, to explore (pedestrian) dynamic behavior in relation to (urban) space. The program uses multi-agent technology to construct an individual-based simulation in which each agent employs individual behaviors. The agents have abilities to navigate through the environment using a behavior rule set derived from a wide range of research – both theoretical and empirical approaches – on spatial behavior in small-scale urban space. These simulated individuals also have the ability to improvise their actions according to the situations they find themselves in. In the simulation, each agent reacts to the space configuration, to specific attractions in the environment, as well as to other mice. The local movement of an individual is, therefore, the result of the interaction of its visual perception, motivation, and social actions. The program then tracks each movement – path of use – revealing patterns that emerge from interactions among the components of the environment. The exploration seeks to develop a way urban designers think of 'space' as fluid processes and recognize that objects in the urban environment can have radically differing effects, depending on the circumstances and contexts in which they exist. Indeed, people are parts of the environment.

summary The construction industry is one that is fragmented by nature. In current practice, information is exchanged between the designers and contractors in the form of paper documents such as drawings, bills of material and specifications. Information is lost and errors are made during the forward and backward exchange of the design-construction information and constructability knowledge between the design professionals, cost estimators and contractors. Despite the technological developments in IT, the industry has been slow in adopting change in its processes. Computer Integrated Construction (CIC) strives to bridge the gaps of information by integrating the tools and processes within the Architecture, Engineering and Construction industries. This thesis proposes an integrated methodology across the design and construction functions supported by available CAD technologies. The proposed methodology has been implemented in a prototype software application named “CAD-B PM” that allows the user to integrate the CAD design with a central database that is a repository of project information. Productivity and cost estimates are generated within the database and are further integrated to a scheduling application for project planning and control. The prototype system provides a unique solution where the project information is openly shared between the applications in a dynamic environment through the use of Open Database Connectivity (ODBC).
