title The city as a street system: A street description for a city ontology
source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary The street system is an important component of the city ontology created for a generative urban design tool and should be able to integrate the many visions or interpretations that designers or other urban design agents may have about streets. This paper describes several characteristics of the street system, with its components organized into object classes which are the shape sets of algebras used by a generation module to generate street network representations that can be assessed by a GIS platform.

summary This article is a starting point for the development of experiential urban co-design interfaces to enhance public participation in local urban projects and to be also used as a communication and collaboration tool in urban design. It is based on the previous research involving 3D city models utilized as understandable design interfaces for the non-technical public (Jutraz, Zupancic, 2011), where we have already explored different views (pedestrian, intermediate and bird’s-eye view), as well as the means by which the information obtained from these different views may be combined by shifting between viewpoints. Previous work was conducted in the “street lab” as well as the Urban Experimental Lab, which was developed specifi cally for the public’s participation in urban planning (Voigt, Kieferle, Wössner, 2009). Presented in this article is the next step that explores the immersive collaboration environment 3D ICC [1], formerly known as Teleplace. The environment was developed for effi cient collaboration and remote communication and shifts the research focus towards questions regarding how to employ both labs as interfaces between the non-technical public and design professionals. As we are facing the lack of digital systems for public participation and education in urban design, different digital tools for communication and collaboration should be combined into a new holistic platform for design. A digital system of tools needs to be developed that supports the urban design decision-making process and focuses on improved final solutions and increased satisfaction amongst all participants. In this article the system of digital tools for public participation, which include communication, collaboration and education, will be also defi ned, with its basic characteristics and its elements.

title 3D Scans of As-Built Urban Scenes in A City Scale
doi https://doi.org/10.52842/conf.caadria.2009.297
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 297-306
summary The purpose of this research is to build digital urban landscape, based on as-built environmental information. Scans were made to an expressway and surrounding buildings through the center of a city. A 3D long-range laser scanner was used to record buildings, plants, and open spaces in a static configuration, plus the records of pedestrians, vehicles, objects in a dynamic form. As the scan tolerance can be controlled in less than 4 mm/50 m, the final urban information management system creates a precise description of objects with colors and textures feasible for internet browsing as well as for infrastructure dimensioning and construction monitoring.

summary The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

summary In sustainable urban development the first stage of the urban design process should consist of a pre-design phase where the context of the site is analysed both qualitatively and quantitatively. In this paper we present a methodology for data mining an urban Geographic Information System (GIS) data set, consisting of three main phases: representation, analysis and description. The process reveals a series of block and street typologies at various levels of detail that highlight the different character of two neighbourhoods. This methodology is demanding in the preparation phase and requires a high level of GIS and statistics expertise in the analysis phase. However, it successfully addresses the complex multi-scale and multi-level nature of cities in a systematic way, providing a tool for systematic profiling of neighbourhoods, which is site and problem specific.

summary In this paper, we suggest a generic city description model suited for purposes like semi-automatic city modeling and urban layout evaluation. The generic city model refers to basic vital functions of a (computable) city. Feature patterns are used to extend the generic city model with global and local characteristics. The Hellenistic cities serve as a platform for a first implementation to test a semi-automatic city model generation. As a result four cities are reconstructed as a first example of our ongoing work, Miletus, Knidos, Priene and Olynthus. Future work will deal with the application of the generic city model to the performance simulation of contemporary urban layouts.

source SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary We propose a three-step participatory design cycle for the early urban design phase that can be integrated into the digital design chain. Step one involves a visualization method that is implemented as an interactive card-based interview technique for the collaborative requirement specification of urban designs. In step two these specifications are a) translated into simplified GIS data and then b) implemented into a grammar-based system together with the corresponding design regulations. The final outcome is a generative and iterative urban model, which includes buildings, building blocks, transportation networks and open spaces that visually communicates spatial impacts of urban design proposals.

summary Recently, many cities in Japan and in other developed nations face problems such as decadence of downtown areas, aged society with a fewer number of children, dependence on automobile transport, etc. And redesign of public transportation services (e.g. tram) is thought to be one of the solutions for these problems. The introduction of LRT is investigated in various places, however, when a public traffic system like LRT is introduced, it is necessary to consider not only the transportation oriented aspects, but also landscapes and plans for a future sustainable city. Therefore, city planners are required to promote workshop-type in the design process to deal with citizens, companies, NPOs, etc. In this research, both components of the VR system for LRT projects and the system that enables the examination from various aspects of traffic, landscapes, city planning, etc., were studied.

summary It has been difficult to locate necessary information quickly in a complicated geo-spatial information network. Textual and numerical information is disadvantageous in that viewers may not have cognitive power and thus do not understand it properly. Besides, it is thought that a particular means is needed to obtain and to understand the information that we need in a given space. Therefore, this study posits that the geospatial information is complex in the construction of future oriented cities, and a new classification system is required for more effective information visualization. This paper also suggests a classification system of urban geo-spatial information and its possible applications as a way to reflect city dwellers’ opinion in city planning.

summary The ultimate goal of the project in which the described research evolves is a computer-platform for assisting in the development of urban design proposals at the site planning scale including formulation, generation, and evaluation modules. The paper is concerned with the development of a common ontology that guarantees inter-operability among the three modules. After clarifying the theoretical framework, it describes the methodology used to develop the proposed Urban Design Ontology (UDO), as well as its lexicon, syntax, and semantics. It is argued that such ontology constitutes the bases for a City Information Model (CIM) that permits to elaborate consistent and comprehensive descriptions of urban spaces, thereby enabling the formulation of programs for urban interventions and the generation of corresponding design proposals.

title Beyond Traditional CAAD: E-Learning supporting design thinking
source Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 71-87
summary A study based on a post-occupancy-evaluation (POE), conducted in housing developments in the region of Campinas, Brazil, evaluated quality of life and sustainability indicators. These indicators were then related to site planning design guideline for low-income public housing projects that considered recommendations for integrated community and security, street and path system and parking, public and private open space and landscaping. Since this work is part of a broader study, which aims to develop evaluation tools, the proposed design guidelines were used by students in a graduate class, in order to verify its effectiveness. Bloom’s Taxonomy was used to determine educational goals for design thinking in this class. First design thinking was instigated based on students’ prior knowledge of life quality and sustainability indicators for housing design. Comprehension of proposed design guidelines was stimulated by the reading and discussion of related literature, paraphrasing or extension of proposed design guidelines and respective illustration with reference images. An existing low-income housing development, with award winning design, was selected and an evaluation of its conformance to proposed design guidelines was conducted comparing site or design images to reference images. This evaluation subsidized a design exercise for the selected housing development. The class was offered as a partially distance course with an agenda including: tutorials, theoretical classes, seminars and conceptual discussions. A new Brazilian open source e-learning environment was experimented and critiqued. Beyond traditional CAAD tools others such as wiki, blog, polls, chat, conferencing, web authoring and visit broadcasting supported collaborative learning and design. Results indicate the viability of design teaching in distance education courses for competent designers; however the experience shows the need for innovation in synchronous communication and visualization tools specific for architectural design users. Students evaluation of selected housing development and final projects indicate that the proposed guidelines for low-income public housing projects successfully supports the decision making process in order to incorporate quality of life and sustainability indicators in design. The experience presents a model of design education which incorporates technology integrated to human and environmental dimensions.

title Interactive Hemostasis Modeling in Urban Network Design
source International Journal of Architectural Computing vol. 7 - no. 3,375-387
summary This paper describes a type of project that images a city as it might exist given the integration of hemostatic procedures within pedestrian networks during emergencies requiring full-scale egress from an urban core. It articulates the steps taken to integrate a pre-existing C++ hemostasis model (C. Jacob, 2008) into Maya software in order to describe how the project operates on a computational level. By projecting these agent-based logics directly into/onto each pedestrian in the city (the smallest unit of the system), egress-oriented infrastructure can shift from being extensively predetermined in form (concrete barriers, metal railing, police barricades, etc.), to something more intensively defined, real-time, and locally on-demand. These procedures are situated within a larger schema based on the structural principles of Norbert Wiener's cybernetic feedback loops, that acknowledge and allow for hybrid (top-down + bottom-up) awareness and control within systems. The project attempts to ally itself with emerging forms of network design with similar structural typologies supported through the use of personal mobile devices (PMDs) in urban environments.

summary “A city can not be designed” Watanabe [1]: our ambition can be at the maximum to guide someway and in some part its growth. So as planners need tools to aid an open design with uncertain goals. This research group beginto develop such a tool at high level of abstraction (Fioravanti 2008), with theaim of investigating the potentiality of a collaboration among complementary research domains. The present work reports about early implementation results of an innovative approach developed by the authors, for representation of design knowledge. It has been identified in the Urban Design Ontology (Montenegro and Duarte 2009) some design entities and their internal relationships that have been formalized and visualized by means of an intuitive interface. As a matter of fact, this approach, by means of inference engines allows coherence’s check and constraint verification, pointing out incompatibility between initial design program and each partial specialist design solution and/or the overall shared one.

title An Interactive Decision Support System for Deriving Plot Ratios Based on the Similarity Relations Between Land Attributes
doi https://doi.org/10.52842/conf.acadia.2009.264
source ACADIA 09: reForm( ) - Building a Better Tomorrow [Proceedings of the 29th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-9842705-0-7] Chicago (Illinois) 22-25 October, 2009), pp. 264-266
summary This paper presents a simple tool for deciding land attribute plot ratios by defining elementary entities and their relationships from the viewpoint of a complex adaptive system. Each entity in this case, a block in the city, is described according to its condition and potential for development, such as land function, accessibility, landscape control, and so on. This not only provides a rich yet subtle identification of each entity, but also creates the basis to establish dynamic interconnections between them. The similarity coefficient, calculated by the comparison between the different blocks’ factors fits well with the explanation of the spontaneous development of the city. The weight of every factor and the threshold of the similarity coefficient are both set as variables, with the optimized value recommended as a default, which ensures a multitudinal application of this software with a focus on different aspects of urban planning. The resultant self-regulatory system with flexible input is not only a credible tool for deriving plot ratios, but also an effective platform to activate urban design creations. The system, as a socio-technical tool, enhances the essential process of urban self-organization and hetero-organization.

title Monitoring urban design through generative design support tools: a generative grammar for Praia
source Proceedings of 15 Congresso da APDR, Cidade da Praia, Cabo Verde.
summary Abstract Urban planning and design has a considerable impact on the economic performance of cities and regions. It is a complex process that extends for a long period and involves many participants. The lack of integrated tools to support this process hampers the ability to maximize the response of plans to contextual conditions while using the least resources. This paper describes research that aims to develop such a tool, integrating formulation, generation, and evaluation capabilities. It is focused on the generation module which relies on the encoding of Urban Induction Patterns (UIP) using shape grammars. A grammar for the extension plan of the city of Praia is presented as one of the case studies used to support UIP definition and illustrate its application. The paper also discusses how the proposed tool can be used for developing and monitoring urban plans.

title Automatic Extraction of Planar Clusters and their Contours on Building Facades Recorded by Terrestrial Laser Scanner
source International Journal of Architectural Computing vol. 7 - no. 1, 1-20
summary Since 3D city models need to be realistic not only from a bird's point of view, but also from a pedestrian's point of view, the interest in the generation of 3D façade models is increasing. This paper presents two successive algorithms for automatically segmenting building façades scanned by Terrestrial Laser Scanner (TLS) into planar clusters and extracting their contours. Since majority of façade components are planes, the topic of automatic extraction of planar features has been studied. The RANSAC algorithm has been chosen among numerous methods. It is a robust estimator frequently used to compute model parameters from a dataset containing outliers, as it occurs in TLS data. Nevertheless, the RANSAC algorithm has been improved in order to extract the most significant planar clusters describing the main features composing the building façades. Subsequently, a second algorithm has been developed for extracting the contours of these features. The innovative idea presented in this paper is the efficient way to detect the points composing the contours. In order to evaluate the performances of both algorithms, they have successively been applied on samples with different characteristics, i.e. densities, types of façades and size of architectural details. Finally, a quality evaluation based on the comparison of planar clusters and contours obtained manually has been carried out. The results prove that the proposed algorithms deliver qualitative as well as quantitative satisfactory results and confirm that both algorithms are reliable for the forthcoming 3D modelling of building façades.

summary For a designer-architect to be able to make accurate predictions for any particular urban space, he/she needs to know the development stages of the city, as well as the city’s various features across time. Thus, it is necessary to read the different segments that constitute the city to reveal its historical, cultural, social, physical and symbolic features. The aim of this study is to determine the social and physical problems of a historical urban space and subsequently to introduce physical and functional suggestions to improve the identified problems, and for the development of the area. The South Haliç Area was chosen as a work-space because of its special importance in protecting the historical and cultural heritage found there and transferring it to future generations. With this in mind, in addition to literature studies, on-site observations and interviews, the area has been analyzed and evaluated using the space syntax method. The suggestions developed for the identified problems and solutions have been re-analyzed, and both the present data and the data obtained after the suggestions have been examined and the results have been presented.

summary This research describes a tool which can be used outdoors instead of a paper medium by a group of people to facilitate city tour guiding or design studies. First, the problems of the device and software which constitute the developed outdoor type MR (Mixed Reality) system were considered. Problems regarding the display, sensor, and composition with video and 3DCG images were clarified. In addition, taking account of the problem that the display is dark outdoors, the luminosity of a number of displays was measured in a dark room and outdoors. In addition to the dark room contrast ratio, the importance of ambient contrast was highlighted through the experiment.

title Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
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. 435-450.
summary Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.
