title Road hierarchy and speed limits in Brasília/Brazil

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,

summary The Urban Decision Room (UDR) should be placed in the tradition of urban design and planning discipline that is taught, and into which research is carried out, at the Faculty of Architecture at the Delft University of Technology. The UDR was developed at the faculty as one of the new design and planning methods with its own specific features. The UDR is specifically aimed at decision-making processes in the practice of urban planning, and particularly at complex urban area development projects. The background to the design enables the UDR to support planning decisions that are made at urban planning element level. The participants in the interactive UDR sessions are asked to provide concrete solutions for urban planning design problems (in terms of preferences for particular functions, number of plots, etc.) and to enter them in a simulation model. A computer network is then used to calculate the common solution space of all the proposals, which is then projected onto a central screen. This outcome generally provides the basis for further discussions and negotiations, after which another round as described above can be held. The paper first focuses on the background and the main features of the UDR system. Secondly, the decision-making issue and a description of a specific Urban Decision Room model, the UDR Heijsehaven will be explained. Thirdly the structure of, and the experiences from, the experimental sessions with the Urban Decision Room Heijsehaven are described. After that the results of the evaluation of the UDR system by participants is presented and finally the follow-up assignment for the UDR system is carried out.

summary The decision support system developed in this research is aimed to the conceptual scheme of project focusing on infrastructure planning and open space design in the architectural context for housing project. Alternative design sets are provided within the limitations, and possibilities to be further evaluated appropriately. This system helps architects and developers to analyze relationships of physical environment, architectural requirements and the overall of project-related factors with real-time cost estimation. Factors for cost estimation derived from the beginning to the end of project will be manipulated simultaneously. Architects and developers can use this design simulation to address the physical data with real-time cost estimation, provide alternative results, and design evaluation for overall project’s feasibility. The software of our research is not just a tool for design & planning automation in feasibility analysis. It will be an interactive decision support system for both developers and planners aspects. The system was developed by SketchUp Ruby Application Programming Interface. The results will be presented into two ways. Firstly, 2D and 3D modeling will be used for interactive visualization in design and planning of the beginning process. Subsequently, numbers and additional factors in details will be used to show relationship between architectural environment and feasibility-based information to help architects and developers collaboratively analyze the land use planning and open space design for housing project. In evaluation process, the developed software is tested with the project preceding and the future project of Bangkok area under constraints and regulations of Building Control Act of Thailand. In conclusion, this system will make effectiveness in design process and management of the construction knowledge. The decision support systems should be designed to makes explicit use of both planning analysis aspect and knowledge-based decision making.

summary Workshops are held with local residents’ participation as one technique by which residents plan roads and places along a route. Because residents without special knowledge participate in such workshops, it is necessary to show the contents intelligibly so that all participants might grasp the plan contents and examine them. Moreover, for community planning workshops, because the time during which they can be held is restricted, within that time, plan- related information must be organized efficiently for rapid examination and searching of its contents. As an interactive system, a real-time simulation (RS) is sought that allows rapid drawing and that has a structure to display the contents of a plan using a three-dimensional space model in real time. The purpose of this research is to build a system that supports environmental space design, which uses RS in the workshop, and which is applicable for evaluation of an actual street space maintenance plan.

title Visual-Physical Grammars
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

summary This paper presents the validation of an office utilisation model for the research project called “User Simulation of Space Utilisation (USSU)”. The result of this research is a system that can be used for analysing and evaluating the space utilisation of a building for any given organisation. A system for building usage simulation that produces data about activities of members of an organisation can substantially improve the relevance and performance of building simulation tools. This is relevant for engineering domains as well as for architects to evaluate the performance of a building design. For a thorough evaluation of the system an experiment was executed for assessing its predictive quality in the context of a real building, organisation and actual human behaviour; this experiment was executed using RFID technology. The result of the experiment was observed data about the space utilisation of the selected organisation. These data were compared with the space utilisation predicted by the USSU system to evaluate the simulation model. The validation of USSU showed that there were no significant differences between the predicated and observed activity behaviour. As a consequence, the output of USSU is considered to be valid.

summary Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new building. A prerequisite for computer-aided planning in the context of existing buildings is both the use of on-site computer aided techniques and the integration of all professional disciplines in an integrated information and communication system. How will computers be used on site in the future? Which equipment will be needed? An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process with and within existing buildings. The aim of this project is the development of a practice-oriented toolbox for the architectural design process based on SAR (spatial augmented reality). This paper focuses on Augmented-Reality based user interaction on site using laser pointer tracking. The project is funded by the German Research Foundation.

title Public Transport Planning Evaluation Tools and theirData Requirements and Availability
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 describes two different public transport planning evaluation tools that are used to support planning activities in The Netherlands and Brazil. In the paper extra attention is paid to data requirements and availability. The Dutch tool generates so-called Public Transport Potential Maps that present the potential of public transport at the level of 6-digit postal code zones based on area and public transport related characteristics. With the Brazilian tool, existing and new implemented public transport routes can be evaluated. To identify urban features that influence the performance of the public transport system, the tool compares characteristics of the urban spaces with the different typologies of public transport routes. Examples of the use of both tools including data requirement and availability are shown in this paper, stressing the fact that GIS is currently an essential and universal tool for public transportation planning, despite the conditions of the site and the complexity of the model under analysis.

summary Through the use of existing digital tools, the research work consists of proposing a new 3D navigation mode based on systemic, practical and graphic assumptions. During the exploration of the Vianden Castle, we outline a graphic representation system as an aid to representation and memorization of archaeological and architectural knowledge. For this, we recompose some concepts related to video games, we materialize the “mental map” described by Patricia Marks Greenfield and we take into account the cognitive capacities of the learner.

summary Urban Design processes need to adopt flexible and adaptive procedures to respond to the evolving demands of the contemporary city. To support such dynamic processes, a specific design methodology and a supporting tool are needed. This design methodology considers the development of a design system rather than a single design solution. It is based on patterns and shape grammars. The idea is to link the descriptions of each pattern to specific shape rules inducing the generation of formal solutions that satisfy the pattern. The methodology explores, from the urban designer point of view, the capacity of a shape grammar to codify and generate urban form (Duarte et al, 2007). This paper defines the ontology of urban entities to build on a GIS platform the topology describing the various components of the city structure. By choosing different sets of patterns the designer defines his vision for a specific context. The patterns are explicated into shape rules that encode the designer’s interpretation of the pattern, and operate on this ontology of urban entities generating solutions that satisfy the pattern’s concept. Some examples of the topological relations are shown.

summary This paper proposes a framework for an integrated computational design system. This design system builds on the strengths inherent in both generative synthesis models and multi-performance analysis and optimization. Four main design mechanisms and their mathematical models are discussed and their integration proposed. The process of building the design system begins by a top-down decomposition of a design concept. The different disciplines involved are decomposed into modules that simulate the respective design mechanisms. Subsequently through a bottom-up approach, the design modules are connected into a data flow network that includes clusters and subsystems. This network forms the Generative Multi-Performance Design System. This integrated system acts as a holistic structured functional unit that searches the design space for satisfactory solutions. The proposed design system is domain independent. Its potential will be demonstrated through a pilot project in which a multi-performance space planning problem is considered. The results are then discussed and analyzed.

title Noncopyright And The Digital Interface To Support The Autonomous Production Of Dwellings
source International Journal of Architectural Computing vol. 6 - no. 3, pp. 279-297
summary This paper presents the discussions on intellectual property crucial for the research group MOM to develop the system IDA (digital interface for supporting autonomous production of dwellings). It first introduces IDA, its conceptual framework, its database and its interactive interface. Then, it examines the arguments for copyright, identifying them as myths or disguises of other intentions, usually based on perpetuating privileges. From that it discusses the way IDA approaches interaction as a means to break the usual logic of perpetuating privileges in digital systems. This leads to examining some anti-copyright movements concluding that they follow the same logic of register of the copyright. Thus, noncopyright seems to be the best means to protest against the current logic and for conveying information towards autonomy of users in their processes of production of space. It also points to an alternative use of computers in architecture as proposed in IDA, which is not based on representation but on interaction.

summary The paper is intended to present the methodological structure of web-based mechanisms related to planning procedures, with particular focus on social participation. The tools provide a link between planners and local community members, allow the acquisition of different sets of data, provide detailed information on the environment and planned transformations, serve as a source of detailed information on the procedure, and last but not least play an educational role, which contributes greatly to the understanding of sustainability, cultural sensitivity, environmental issues, planning concerns on a wider scale. Web-related technology provides many opportunities to reach for a wider social participation and simultaneously to receive more representative feedback from the local community. The article will discuss in detail some results of the implementation of the Citizen project – a web-based platform supporting the social participation.

summary MxR—pronounced “mixer”—is a Mixed/Augmented Reality system intended to support collaboration during early phases of architectural design. MxR allows an interdisciplinary group of practitioners and stakeholders to gather around a table, discuss and test different hypotheses, visualize results, simulate different physical systems, and generate simple forms. MxR is also a test-bed for collaborative interactions and demonstrates different configuration potentials, from exploration of individual alternatives to group discussion around a physical model. As a MR-VR transitional interface, MxR allows for movement along the reality-virtuality continuum, while employing a simple tangible user-interface and a MagicLens interaction technique.

summary Urban design is concerned with the shape, the surface and the physical arrangement of all kinds of urban elements, the basic components that make up the built environment, at the level of buildings, spaces and human activities. It is also concerned with the non-visual aspects of the environment, such as noise, wind and temperature and humidity. The city square is a particular urban element which can take many forms and its geometrical relationships such as maximum dimensions, ratio of width to length and building height to length have been analysed for centuries (Alberti 1475), (Vitruvius 1550), (Sitte 1889), (Corbett 2004). Within the current urban design process there are increasing examples of three dimensional computer representations which allow the user to experience a visual sense of the geometry of city squares in an urban landscape. Computer-aided design and Virtual Reality technologies have recently contributed to this visual assessment, but there have been limited attempts at 3D computer representations which allow the user to experience a greater sense of the urban space. This paper will describe a survey of computer tools which could support a more holistic approach to urban design and which could be used to simulate a number of urban texture and urban quality aspects. It will provide a systematic overview of currently available software that could support the simulation of building density, height, colour and style as well as conditions relating to noise, shading, heat, natural and artificial light. It will describe a methodology for the selection and filtering of appropriate computer applications and offer an initial evaluation of these tools for the analysis and representation of the three-dimensional geometry, urban texture and urban quality of city centre spaces. The paper is structured to include an introduction to the design criteria relating to city centre spaces which underpins this research. Next the systematic review of computer software will be described, and selected tools will undergo initial evaluation. Finally conclusions will be drawn and areas for future research identified.

summary Recently, urban planning has largely placed the user at street as the centre of infrastructural design, with significant implications for the perceived attractiveness of user environments. The urban designers faced with the task of designing such spaces, needs a tool that will allow different designs to be compared in terms of their attractiveness as well as their effectiveness. Therefore, this paper applies the selective attention theory and establishes a pedestrian behavior model that embeds the behavior-based rules and attributes of an agent. We call this simulation platform to be an agent-based street simulator (ABSS). Through experiments and verifications on cases of real-life urban streets, the system and its applications, and major findings are reported.

title Constraint-Based Design in Participatory Housing Planning
source International Journal of Architectural Computing vol. 6 - no. 1, pp. 97-117
summary We introduce some novel ideas for a constraint-based design strategy to support participatory housing planning processes in Latin America. The following lines intend to open the discussion on the requirements and effect of the computer implementation of a constraint satisfaction approach to solve elementary design problems in architectural practice. The case study applies to the building massing design problem posed by the Chilean urban regulatory framework that addresses single-family affordable houses. Two different implementation criteria are being tested in an ongoing series of trials providing further considerations. One prototype uses MAXON's CINEMA4D XPRESSO® visual scripting environment to set up a semi-automated design environment which allows users to edit one feature-based 3D model of massing alternative at a time. The other prototype uses ILOG's OPL STUDIO® constraint programming environment to achieve fully automated search and 2D visualization of all possible solution alternatives to separate subdomains of the building massing design problem.

summary The proportion of planning activity that concerns existing buildings is increasing steadily throughout Europe. In Germany it is estimated that already two thirds of architectural planning tasks are related to revitalisation, modernisation, conversion and reconstruction. For these types of projects in particular, clients are interested in obtaining an estimate of the building costs as early as possible. Because many details are unknown or can only be guessed, it is often difficult to make a reliable estimate. This article describes a software concept for the rapid, sketch-based capture of data on site with a view to obtaining a cost-assessment for a series of different revitalisation variants using a stochastic approach.
