title	Parametric Modeling as a Design Representation in Architecture: a process account
source	Third CDEN/RCCI International Conference on Education, Innovation, and Practice in Engineering Design, Toronto, ON, Canada, 24-26 July 2006. Canadian Design Engineering Network. Published on CD.
summary	Disciplines outside of engineering, for instance, architecture, are adopting parametric modelling as a design representation. This paper reports on three aspects of the adoption process, which is largely being conducted through multi-day workshops outside of formal university course settings. Fist, the structure and process of such workshops may be a model for interdisciplinary learning and university-industry liaison. Second, students learning parametric modelling must master skill different from that required for non-parametric representation. Third, the parametric modelling strategies being developed in architecture may have both similarities and differences to those used in engineering.

title	Design Tools for Pervasive Computing in Urban Environments
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 467-486
summary	In this paper we report on ongoing research in which the implications of urban scale pervasive computing (always and everywhere present) are investigated for urban life and urban design in the heritage environment of the city of Bath. We explore a theoretical framework for understanding and designing pervasive systems as an integral part of the urban landscape. We develop a framework based on Hillier's Space Syntax theories and Kostakos' PSP framework which encompasses the analysis of space and spatial patterns, alongside the consideration of personal, social and public interaction spaces to capture the complex relationship between pervasive systems, urban space in general and the impact of the deployment of pervasive systems on people's relationships to heritage and to each other. We describe these methodological issues in detail before giving examples from early studies of the types of result we are beginning to find.

title	Simulation of Micro Pedestrian Behaviour in Shopping Streets
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 101-116
summary	Over the years, scholars have developed various models of pedestrian movement. These models can be used to assess the effects of detailed design decisions or to predict pedestrian behaviour under conditions of crowding. To date, not much attention has been paid to pedestrians' shopping behaviour at the micro level. Therefore, the main purpose of this project is to test a model that aims at simulating micro pedestrian behaviour in shopping streets, including entering shops. The model assumes a detailed network of links to represent the structure of street segments and entrances to the shops. The basic principle underlying the model is that a pedestrian moves from one link in the network to another, adjacent link. In fact, a pedestrian enters a segment at one side, heading for the other side of the segment. However, a pedestrian might enter the segment by leaving a shop as well. Then, the pedestrian might be heading for either side of the segment. While transferring from the current link to the next link, the pedestrian will be attracted by the shops along both sides of the street. The study area is Antwerp's main shopping street. During a one-week workshop in July 2004, students observed pedestrian movement in this shopping street. An inventory of some physical characteristics of the shopping street was made and pedestrians were tracked through two separate segments of the shopping street. In total, 334 pedestrians were tracked. A conventional multinomial logit model is used to simulate pedestrians' micro behaviour. The process of consecutively selecting links continues until the pedestrian has reached one of the terminal links or a shop. The model performs very well. Simulated routes were used to assess the validity of the model. Observed and simulated link loading correspond fairly well, however, the model seems to slightly mispredict the attraction of a number of shops.

title	SynBio-Design: Building new infrastructures and territories with Synthetic Biology.
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 1213–1224
summary	Which kind of imagination do we need for the future of our planet? In the past 150 years, we have completely transformed our biosphere. Today we have arrived at points of no return in global warming! The temperature of the Arctic Ocean will increase by 3-5°C by mid-century. This will lead to disastrous ocean acidification, sea-level rise, and worst of all the thawing of the permafrost that will release 1 trillion tons of carbon dioxide into the atmosphere. In this paper, we argue that building with biology will be the most important force to transform our planet. Since 2006, Synthetic Biology (SynBio) has surfaced as the fastest-growing technology in human history. SynBio involves emerging techniques that allow us to design, edit, and engineer all kinds of living organisms. In this paper, we elaborate on its potential development in growing infrastructures and its impacts on architectural thinking.

summary	The digital technology and the integration of knowledge between musicians and architects it’s presented as a unique platform to explore and give a new meaning to the bonds between Music and Architecture. The presentation describes the experience and the results of creative process that link a group of music and architecture students and teachers for a hypermedia composition. The processes are orientated to the simultaneous construction of products from two approaches: from music to the form (plastic or visual), and vice versa. The exploration begins from musical assignments and it’s limited to two types of situations and creative bonds with digital technology: • Independent actions of the subject-musician and subject-architect. • Conjoint actions of both subjects. // The conclusions allow to evaluate the degree of measurability of the process taken care and possible derivations of the particular interpretations of them in each situation.

summary	The theme of this conference builds on and investigates the pre-existing and endlessly unfolding relationship between two domains of scientific inquiry: Architecture, urban design and planning, environmental design, geography and Social theory, media and communication studies, political science, cultural studies and social anthropology. Architectural design involves communication and could thus be partly considered a communicational activity. Designers (or not) see architectural designs, implicitly, as carriers of information and symbolic content; similarly buildings and urban environments have been “read” and interpreted by many (usu- ally not architects) as cultural texts. At the same time, social and cultural studies have studied buildings and cities, as contexts for social and cultural activities and life in general, from their mundane expression of “everyday life” (Highmore, 2001) to elite expressions of artistic creativity and performance. Information and communication technologies (ICTs) support both of these levels of scientific inquiry in many ways. Most importantly however, ICTs need design studies, architectural and visual design, social and cultural studies in their quest to create aesthetically pleasing, ergonomically efficient and functional ICT sys- tems; this need for interdisciplinarity is best articulated by the low quality of most on-line content and applica- tions published on the web.

title	Blurring the Lines: Computer-Aided-Design and -Manufacturing in Architecture
source	Wiley-Academy, London 224 pp. Architecture in Practice series
summary	The first few years of the 21st century have seen a revolution in the ways that we think about designing and making buildings. In no other area is this more apparent than in the interface of computer-aided design (CAD) and computer-aided manufacture (CAM). The potential blurring or assimilation of these two systems holds the still elusive but golden promise of a direct, smooth transference of design data into large-scale production facilities in which components are directly cut, modelled and moulded. How far off are we from seeing the widespread adoption of this technology? What is the potential for CAD/CAM beyond tailor-made forms? In the future, what is the possibility of complex, large-scale forms being run out in mass-customised buildings?

summary	With the development of ubiquitous computing (Weiser, 1991), what will become of the traditional media such as pen and sketches, especially in the design education environment? Or what will they be transformed into? In this research, we focus on the interior design process with a particular type of media-1:1 spatially augmented reality design environment (SARDE). In this research, we tried to implement SARDE and have a scenario experiment to check how designers interact with such design media. Furthermore, through this research, we have come to know more about how designers use design media to represent their design dream.

summary	This research presents the new orientation of the combination of digital modelling with generative programming and joint method of traditional wood structure for manipulating Rapid Prototyping to explore the assembling of free form objects. The presenting of the example indicates that the edition of Maya scripts defines the purpose of design. Through the discussion on scripts developing the assembly of the free-form objects of frames and surfaces and through the achievement that RP produces and examines objects, we bring out the possibilities of the new form developed from the old structure and illustrate how to develop our hypothesis. The developed result could provide the possible new way for free-form assembly. We expatiate our research process and final achievement and provide a new thinking direction in the education field.

title	SCALE - A street case library for environmental design with agent interfaces
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 137-150
summary	Urban space provides a context for human interaction. Recently, urban planning has largely placed the user at the street as the centre of infrastructural design, with significant implications for the perceived attractiveness of user environments. However, visual observation is often difficult for verifying planning goals. The simulation of pedestrian behaviour is important for physical planning, but such research is scarce. In this study, we adopt an empirical approach for generating reactive path following. Further, we implement scenarios as computer scripts with agent-based interfaces to identify navigational patterns. Moreover, we built a hierarchy of individual behavioral models and define a behavior production system to control the agent. Key attributes of streets such as rest space, utilities, landmarks, and buildings have space tags as identifiers to associate streets with related activities.

title	The VIPA project - some notes on the pedagogical approach to design education using active 3d worlds
doi	https://doi.org/10.52842/conf.ecaade.2006.470
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 470-477
summary	This paper should be seen as complementary to the other papers by Mullins et al where the EU VIPA project is described. It is the intention of this paper to deal solely with the educational aspects of using computers in architectural education, which of course is the raison d’etre of both ECAADE and the VIPA project, but on this occasion to look at the earliest models of this, to revisit the pioneers in case we have forgotten something and to see in what way their original aims were achieved and how their self proclaimed task can be transferred into the current situation. It is the intention of this paper to argue that Papert and Kay’s use of the computer in education still has many useful things to say in the context of vipa. The general approach is fundamental to the VIPA project and will inform the ongoing design of the scripting and modelling platform, based on Smalltalk / Open Croquet, and Blender / Python.

summary	This paper discusses tools and strategies to support the capturing and use of knowledge embodied in design practice. The tools described are part of a system conceived as a suite of modular tools, KMan, to be developed and adopted incrementally and independently, in the framework of a wider organizational knowledge management strategy. The concept of knowledge pebbles is introduced to describe collections of heterogeneous data formats to form a unit of potential knowledge In the final section of the paper an overview of all the tools part of the system is presented and some of the tools described and illustrated in more detail. In particular the Brief Management Tool, the Generic Search Tool and the Pebble Creation Tool are discussed.

summary	Simulating the development and the image of architecture and urban design means to show how the environment of the future and the living conditions could develop. At the same time it is part of our task to explain our work to local people and to the public and to passion skills in methods, instruments and knowledge in planning to the next generation of architects, planners and last but not least to discuss and to renew them once more for ourselves. Our aim was also to reflect what we have done since starting the look through the key-hole of endoscopy. Meanwhile this look has been completed since the beginnings in 1993 much more by computer and monitor. It is not the question to take the endoscope or the computer as a methodical and instrumental approach. Nowadays we normally decide to take the endoscope and the computer. In preparing the conference and the workshop we thought that this should now also be the moment not only to inform each other and the participants on methods, tools and best practices in simulating and designing the environment but also to focus on the social and human consequences of perception, movement and use the present urban spaces and the urban space in future. So we proposed the theme “MOTION, E-MOTION and URBAN SPACE” and we invited a scientific expert in experimental psychology to give us some serious reflections and one or another hint on our research themes and methods. The contributions and discussions in the conference showed that the proposal has not only been accepted but has also been completed and enriched especially concerning the theme urban space, it’s processes of usage and it‘s atmosphere. Also in the themes of endoscopy and the research on modelling urban spaces and architecture, meanwhile nearly “traditional” ones, remarkable results were presented and discussed. A very important point of contributions and the following discussions was how to present our subjects to the interested public and to improve our own internal exchange. An object could be to enforce the research tasks in researching together even more.

summary	This paper focuses on the capabilities of choice models in assisting planners in the development of transport policies and interventions for strategic transport planning for urban systems. Models are looked at as part of a decision support system for the development of transport measures for sustainable mobility. The use of participation is looked at as a tool for the understanding of the real needs in terms of mobility in the complex contemporary society and for the construction of the future transport scenarios and transport alternatives.

title	A Grammar for the Patio Houses of the Medina of Marrakech - Towards a Tool for Housing Design in Islamic Contexts
doi	https://doi.org/10.52842/conf.ecaade.2006.860
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 860-866
summary	The goal of the research described in this paper is to develop a computational model of the Medina of Marrakech in Morocco. The ultimate goal is to develop a system that could capture some of the characteristics of traditional Muslim cities fabric and use it in contemporary urban planning. Previous papers have proposed the use of three grammars to encode the spatial complexity of the Medina: the urban grammar, the negotiation grammar, and the housing grammar, and addressed the development of the urban grammar. This paper proposes a grammar to describe the formal structure of the houses, the first step in the developments of the remaining two grammars. It describes the set of rules and then illustrates its application in the generation of an existing house. The basic formal structure consists of three concentric rectangular rings with the patio in the middle. The location of the entrance and the staircase are fundamental for the definition of the basic layout.

summary	Subject of study is the possible organisation of the Olympic Games of 2028 in the Netherlands, as seen from an urban development viewpoint. The project focuses on the decision-making process in the initiative phase. Aim of the project is the development of a decision support tool for the complex, interdisciplinary decision-making process which should result in an optimum interorganisational design. The methodology used to find the optimum choice is the combination of sub-solutions. Preference Measurement modelling based on a multi-criteria decision analysis is the technique employed. The group decision is a choice out of a number of Olympic urban development combinations, which is made in such a way that the preferred combination is the 'best' among the possible candidates for all relevant stakeholders.

summary	In this paper, we present a method that allows designers to interactively create partially self-similar manifold surfaces without relying on shape grammars or fractal methods. The modellers that are based on traditional fractal methods or shape grammars usually create disconnected surfaces and restrict the creative freedom of users. In most cases, the shapes through conventional fractal or shape grammar methods are defined by hard coded schemes that allow limited interactivity for the design process. We present a new approach for modelling such shapes. With this approach, we have developed a simple generative tool with given adjustable parameters to achieve variety of conceptual forms. Using this tool, designers can interactively create a variety of partially self-similar manifold surfaces.

title	Evolving Urban Structures using Computational Optimisation
source	Proceedings of the Generative Arts conference, Milan, 2006
summary	This paper investigates the use of computer analogies for naturally inspired optimisation techniques as an aid to developing the site layout and massing for the new World Trade Centre development in Pristina Kosovo, which is being designed and developed by 4M Group architectural company, in conjunction with the Advanced Modelling Group Aedas. The development of a genetic algorithm will incorporate various techniques, that have been developed in the field of multi-objective optimisation, to create three dimensional massing models, and site layout solutions which partially fulfil the Prisina brief requirements, which are taken from specifications created by 4M Group. Genetic algorithms are based on natural evolutionary principles which are explained in this paper. It will incorporate Pareto concepts to manage the optimisation of the various objective functions. For example, these will include volume and position of units, which will ensure that the different and sometime conflicting needs of the site are balanced throughout the optimisation. This type of problem is often known as an NP-complete (non-determinate polynomial time) problem. This will provide architects and planners with a number of Pareto optimised site massing solutions as an aid to the design process. An initial investigation into the specifics of the Pristina site requirements, will be followed by an investigation into the the genetic algorithm which is created in Visual Basic for Applications (VBA) linked with AutoCAD as the graphical output of the code. The embryology (development) of the various solutions from the genetic information incorporates an ‘ant’ pheromone trail model, which simulates the action of ants during food foraging, as a tool for initial route planning within the site. Diffusion and cellular automata are used during the development of the solution to construct the massing for the site.

title	Automatic Semantic Comparison of STEP Product Models - Application to IFC product models
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 447-463
summary	This paper introduces an original method to compare IFC models and more generally any STEP models. Unlike common 'diff-like' tools which compare textual files by proceeding line against line, our approach compares actual graphs created from STEP-files. Therefore added, removed, and changed objects can be tracked between two versions of the model. Besides, this standalone tool does not need any heavy database to work so it is fully adapted to design methods of construction projects, where actors are free to modify a local version of their project without any dependence on the database. Moreover it is reusable for other industrial fields thanks to its compatibility with any STEP model. This tool is a part from a more global project which tends to improve accessibility and sustainability of IFC therefore it can be used as a support for VR based design tools.

summary	Simulation is a means to help urban planners and investors to optimize inhabitant satisfaction and return on investment. An example is the optimal match between household preferences and property profiles. The problem is that not enough knowledge exists yet about dynamic user activity models to build reliable and realistic simulators. Therefore, we propose a modeling and software technique that produces simulator prototypes very efficiently for the development, test, and evaluation of many different user activity models, using executable models, code generation, and a domain specific software process. As a specific feature, the model is based on many agents acting independently from each other and that are mapped in several refinement steps into the same number of concurrent processes. The housing example is used as a case study to explain the process and show performance results.
