title	Co-operation and Complicity Voices, Robots, and Tricksters in the Digital Marketplace
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 162-175
summary	We advocate the theme of complicity, ahead of co-operation, as a means of understanding complex, interactive digital systems. Our case study of a market precinct known as the Barras, about one mile from the centre of the city of Glasgow, foregrounds the notion of complicity. Market places are characterized not only by co-operation in rule-governed environments, but complicity between actors as a means of breaking rules, working at the boundaries of formal frameworks, avoiding other actors, such as law enforcers, and even working with them in tacitly agreed evasion strategies. We present the human voice (as exercised in the case of market stall holders drawing attention to their wares) as a major medium of complicity. In our application of these ideas we deploy Lego Mindstorms TM RCX robot processing to explore interactions between a mobile sensing robot and simple environmental controls: movements of sliding screens in response to an autonomous mobile sensor. As well as their benign characteristics as co-operating agents, we argue for a consideration of robots as quintessential tricksters, plotting and scheming strategies of survival, evasion and opportunism. Traits that can be employed in the development of useful augmented environments.

title	Digital Masterplanning: Computing Urban Design
source	In Urban Design and Planning: Institution of Civil Engineers, Thomas Telford Publishers, ahead-of-print
summary	The digital revolution has finally reached urban design as one of the last design communities not very familiar with computing. This is despite the city and geography being the natural fields for systems analogy and digital models of mathematical and statistical simulation were developed in the 60s and 70s for urban planning, much before industrial or architectural design. The recent arrival of urban design simulations is however not as innovative and radical as their 50 year old counterparts since they use computing solely for policy visualization, quantity evaluation or pattern generation. The Computational Design and Research Group [CDR] at Aedas\|R&D started in 2007 to develop an open platform of lightweight applications – Digital Masterplanning – in collaboration with partners from academia and industry to provide methods for urban design, based on computational methods called meta-heuristic algorithms. An attempt to encode empirical knowledge and design assumptions into simulations is described where designers can assemble the resulting applications according to scales and brief into custom workflows.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title	Conscious Interaction with Immaterial Space: Augmented Reality of everyday life
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 243-252
summary	This paper describes an on going research that uses design experimentation to provide an insight into different modes of space representation – in this case, physical, augmented or virtual space – and the type of experience triggered by their juxtaposition. We investigate, thus, how the simultaneous labyrinthic navigation and the moving or “shifting” “overview” enrich our experience of the city and “bring forth” the function of the bus-stop as an intermediate space of transition. We also question the way in which one perceives his/her own body spatiality and motility in physical, augmented and virtual environments, and how the particular kind of experience created by this juxtaposition, “brings forth” one’s awareness of his/her navigation in the city, or the instrumentality of the specific place. Our theoretical approach highlights issues pertaining to embodiment, spatiality, consciousness, intentionality, virtuality and immateriality.

title	History and 3D City Models: An Analysis of Digital Representations of the City Evolution
doi	https://doi.org/10.52842/conf.caadria.2007.x.h2u
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Through the evaluation of advantages and limitations of 3D historic city models, this paper aims to analyze the contribution of those tools to the city history representation. One should overcome limitations such as incomplete information, impediments to acknowledge hypotheses representations, intense labor requirements or difficulties to encourage a historical reflection. We argue that creative systems that are carefully planned towards history’s thorough understanding are more effective than those applications which focus on the development of high quality images. Those issues are illustrated by the system prototype “Rio-H”, which presents an alternative to communicate the history of Rio de Janeiro, Brazil.

source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 343-350
summary	This year, for the first time in history more people are living in cities than in the country. This fact induced us to look at the topic of city modeling from different sides. In this paper we introduce novel approaches that contribute to the generation and visualization of dynamic complex urban systems. We distinguish reality-based and generic city models. On the one hand we look a three dimensional models of urban environments. On the other hand we are looking at the key challenges and trends that will shape future cities. We are drawing parallels to functional models of brain circuitry. City modeling as a case in point provides the basis for our research to arrive at a transdiciplinary theory of design and modeling.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 355-358
summary	This article contributes to comprehend how socialization by communication networks influences the dynamics of use and occupation of city spaces. The urban space is analyzed according the relations between the electronic spaces and the social space of every day. It interests us how the physical structures of urban spaces and the virtual space contribute to shape one single space, as an interface relational, that serve to organizing and representing the collectivity that use them.

title	The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary	At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

title	Procedural Design of Urban Open Spaces
doi	https://doi.org/10.52842/conf.ecaade.2007.351
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 351-358
summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

title	SecondLife: A Computer-Mediated Tool for Distance-Learning in Architecture Education?
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 17-34
summary	Despite the importance of distance learning for its ability to reach a wide audience, easiness to access materials, and its lower cost compared to traditional learning, architecture education has not been well served by distance education. This is because it has a higher level of learning objectives, it is taught by coaching methodologies, and involves nonverbal forms of communication. One of the most common learning methods used in the design studio is the Criticism/Critique, which is a graphic and oral type of communication between the tutor and the students. In this investigation, Second Life, a massive multi-user online virtual environment that offers three-dimensional spatial capabilities via Avatars impersonation, is used as a computer-mediated tool for text and graphic-based communication in a distance learning situation. The study describes a demonstration experiment where students had to communicate with their tutor, display and describe their projects at a distance, in a purposely designed criticism space in SecondLife. The main objective of this paper is to observe and document the effects and the use of SecondLife virtual environment as an online 3D graphical-based tool of computer-mediated communication in distance learning in architecture education. The study also answers some questions: How well did the students use the tools of the medium provide? Was there a sense of personal communication and realism gained through using Avatars in the virtual environment? Did SecondLife provide a successful means of communication for a graphic-based context? And what are the students’ opinions about the learning environment? Using multiple methods of data collection, mainly based on an electronic observation of the experiment, questioning the participants before and after the experiment, and the analysis of the chat transcripts, the study presents descriptive results of the experiment, and discusses its main features. Proposals for modifications are made for future replications.

title	Readiness for the Use of Technology for effective learning via the vds: Case of the United Arab Emirates
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 439-456
summary	Review of the literature indicated that today’s knowledge-driven economy demands a workforce equipped with complex skills and attitudes such as problem solving, meta-cognitive skills, critical thinking and lifelong learning. Such skills can be acquired if learning and teaching are guided by the constructivist and cognitive learning theories. In particular, the constructivist approach emphasises effective learning processes based on learning by doing and collaboration. This approach is congruent with use of technologies, such as Virtual Design Studio (VDS), for the purpose of architecture education in design courses, but such use is lacking in the United Arab Emirates (UAE). It is thus important to assess the extent to which the constructivist and cognitive theories are implemented in teaching design courses in the Architecture schools of the UAE. It is also important to assess the effectiveness of employing technology in general and VDS in particular in implementing these theories. The author intends to study the relationship between effective learning on one hand and using VDS in implementing the constructivist and cognitive approaches on the other hand. Thus, the author conducted a preliminary study to gain a basic understanding of the difficulties, approaches, attitudes, perceptions, and motivation related to the learning of design in architecture schools in the UAE. Second, the investigation was designed to assess the extent to which the students would be interested in the use of sophisticated technology in the teaching and learning environment in the UAE architecture education schools in order to achieve effective learning. The study has been conducted in the United Arab Emirates University (UAEU). Methodology used for this was the focus group method. In addition to the focus group interviews with the UAEU students, unstructured individual interviews with lecturers from UAEU and the American University of Sharjah (AUS) have been carried out. Data analysis showed that students were not satisfied with the current teaching methods based on traditional lectures. It was concluded that students were ready to practice effective learning of design via the intermarriage of VDS and the constructivist and cognitive approaches. An ambiguity that remained was whether students were ready for assessment methods which are consistent with the constructivist approach.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 375-379
summary	Brazil has so many historical cities with important architectural heritage. Some of them are remains of the colonial times and aggregate beautiful buildings such as, palaces, public buildings and churches in baroque style, legacy of the Portuguese colonization. Despite of its cultural value, most of these building sets are under several kinds of threats. This paper discusses about the experience on digital photogrammetric restitution of the building façades of Pelourinho, a neighborhood in the historical center of Salvador, the capital city of the State of Bahia. The architectural documentation is an important way to preserve and safeguard its memory, besides being an effective educational process about the meaning of preservation and cultural heritage.

summary	In this paper evolution of CAAD teaching at architectural faculties will be presented. The CAAD will be considered as one of the components of skills and knowledge needed to support Design Studio. The paper is focused on the question “How architectural design may be combined with CAD teaching?” Formulation of this question results from opinion that position of CAAD in teaching of architectural design curriculum is different than other disciplines being taught at architectural schools. Introduction of CAAD to teaching schedules unquestionably and explicitly uncovered the need for changes within the whole schedule of study. Although great number of computer equipment is used, the students are still being taught as in the XIX century. In terms of achieved results it proves ineffective. Analyses have shown that evolution of teaching methods may be divided into four stages: software teaching, “personal involvement”, “replacement” and integration.

title	Detecting Inefficient Lighting Solutions: Step-by-Step Geographic information system (GIS) Technique
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 491-504
summary	Outdoor lighting is used to illuminate roadways, parking lots, yards, sidewalks, public meeting areas, signs, work sites, and buildings. It provides us with better visibility and a sense of security. When well designed and properly installed, outdoor lighting can be and is very useful in improving visibility and safety and a sense of security, while at the same time minimizing energy use and operating costs. But, because nobody thought at this, most street lights shine light not only on the nearby ground, where is needed, but also miles away and skywards. Thus a large fraction of the light is lost, at consumer expense and without his/her consent. In the other hand, shortage in street light may cause more crimes as well as accidents. Most of the wasted or short light comes from the poorly designed street lights. Billboards, decorative lights, poorly shielded security lights are part of the problem too, but the main culprit for the waste and ugly glow one sees above one's head at nights is from the streetlights. Thus, recent computer technology gives us tools to be employed for testing the quality of light. Geographic Information System (GIS) software could be utilized to achieve that mission through applying mapping technique. This technique could analyze digital photographs and define light polluted areas as well as bad lighted. This paper reveals that step by step technique, which employs hybrid technologies to solve such problem for better planning decisions.

summary	Digital Technology has transformed industrial manufacturing and production; and an array of Industrial Design products provide increasing comfort and benefit to millions of global citizens via ergonomic and mass production/customization strategies. Yet, housing needs of a rapidly growing global population are rarely affected by digital technology. Shifts in societal demographics, from rural to urban city centres, and concurrently Global Warming and ecological changes are exacerbating the world housing situation. Millions are homeless, live in inadequate shelter, or as in the US Manufactured Housing (MH) market, live in nondurable poor quality “manufactured” houses that are detrimental to health, at best, or during extreme weather events, suffer catastrophic damages often resulting in death to occupants. Nevertheless, housing concepts and related living units have benefited very little when compared to architecture’s related manufacturing industries counter-parts (i.e. automotive, aerospace, marine industries, etc). While Technology has vividly expanded the shape language of architecture (i.e. Free-Form-Design), some may argue that Free-Form- Design buildings generally have beauty that is only “skin deep” and typically focus on providing signature statements for both the designer and elite clientele. In this paper, we will briefly review the role of the architect in the US Manufactured Housing industry; additionally, we will identify the major problems that plaque the US Manufactured Housing Industry. Further, we will review how architects and Industrial Designers use technology in their respective fields and draw larger designmanufacture principals for issues of global housing. Our findings and analysis suggest that an Industrial Design approach, applied in architecture for mass housing, offers a means of improving the architect’s role and technology in manufactured housing for the masses.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	The purpose of this paper is to explore the type of social interactions that can be generated when a technological platform is introduced in a public environment. Here we present an interactive urban installation, which use a body-input as a form of a non-traditional user interface. Its aim is to enhance novel experiences that can enrich interactions between people nearby, sharing the same space and the same playful atmosphere. The prototype incorporates a grid of lights that dynamically generates patterns according to pedestrian’s position over the carpet. The installation was tested in various locations around the City of Bath, UK.

title	Mindful Spaces: Computational Geometry and the Conceptual Spaces in which Designers Operate
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 611-624
summary	Combinatorial computational geometry, while dealing with geometric objects as discrete entities, provides the means both to analyse and to construct relationships between these objects and relate them to other non-geometrical entities. This paper explores some ways in which this may be used in design through a review of six, one-semester-long design explorations by undergraduate and postgraduate students in the Flexible Modeling for Design and Prototyping course between 2004 and 2007. The course focuses on using computational geometry firstly to construct topologically defined design models based on graphs of relationships between objects (parametric design,) and concurrently to output physical prototypes from these "flexible models"(an application of numerical computational geometry). It supports students to make early design explorations. Many have built flexible models to explore design iterations for a static spatial outcome. Some have built models of real time responsive dynamic systems. In this educational context, computational geometry has enabled a range of design iterations that would have been challenging to uncover through physical analogue means alone. It has, perhaps more significantly, extended the students' own concept of the space in which they design.

summary	An exploration of streetscape lighting that responds to site phenomena provides a basis to explore the abilities of sensor driven devices to construct landscape form. The project expresses multiple reactive spaces through a hypothetical design project on Pine Street in New York City. The landscape is the input using the variables of wind, sound, motion, and light in order to focus, open, lower, and contract each lighting device. As the landscape progresses throughout the day, season, and/or year, various relationships are created in form and light to organize spaces on multiple scales. Data becomes the armature for scripted reactions allowing the infrastructure to respond for safety or efficiency. With the proliferation of sensor networks and sensor systems, the possibilities arise for the re-articulation of data expression. The single lighting device works within a network that is connected by the specifi c phenomenology of the site. The project is grounded historically in the landscape folly, an architectural device that is not what it appears to be (Figure 1).
