title	The topics of CAAD: An evolutionary perspective – a research for representing the space of CAAD
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 626- 641
summary	This paper is concerned with the ongoing changes and the evolution of CAAD using machine-assisted techniques. It is feasible to create a hypothesis of the identity of the discipline depicted in the archived published output, and semantically link it to the data cloud. This allows for expansion of the meanings embodied in the research and inference about what CAAD is, and to trace back how the field progressed. We present several case-studies showing how this inference is done and finally, observations are elaborated and an outlook on further work is discussed.

title	The Impact of Three Cognitive Functions on Digital Media Aided Architectural Ideation: A Proposed Investigation
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	From a cognitivist perspective the architectural design seen as an iterative process of search for an “acceptable” solution from initial design assumptions (Simon 1974) requires representation. These representation which may be internal (mental/cognitive activities) and external (sketches 3D models) are essential to any creative act and in all phases of the design process since they constitute a projection of the architect’s thought and know-how.

title	Building design as individual compromise between qualities and costs: A general approach for automated building generation under permanent cost and quality control
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 458-471
summary	We introduce an evolutionary design approach for the automatic arrangement of a predefined space program on a given site. The design goal is to distribute floor spaces while ensuring the essential building performance and usage. The presented evolutionary strategy is applied to acquire optimal design solutions considering both environmental conditions and inner organization under diversified fitness functions. The evaluation process consists of the direct analysis of the spatial network and the physical factors in an adequate accuracy. The method provides a fast generation of qualified volumetric studies. The resulting buildings become a manifested compromise between qualities and cost.

summary	There is an increasing demand for building performance assessment among architects mostly due to a rising awareness for issues related to environmental sustainability. However, after thirty years of research, interoperability of performance analysis tools with CAAD environments is still far from being seamless. Yet, all commercial CAAD vendors have recently started offering an array of building analysis tools. It is fair to expect a new surge of efforts in integrating prediction and evaluation capabilities within CAAD systems over the next few years. Building on lessons learned, this paper argues the need for a unification infrastructure for building performance and outlines the requirements for building an analysis network.

title	An evolutionary system for design exploration
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 259-272
summary	This paper reports on the development of a multi-objective evolutionary developmental design environment, called EDDE. The goal of the system is to make it easier for designers to use evolutionary techniques to explore design possibilities. The system consists of a generic evolutionary core into which a set of design specific scripts need to be plugged in. The system uses a web based client-server architecture that can either be run on a single computer or on multiple computers in parallel. Initial experiments have shown the system to be effective in evolving designs.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 159-172
summary	This work focuses on the development of a tool capable of assisting and supporting architectural design activity. We propose an evolutionary mechanism through the use of a genetic algorithm. Environmental parameters are convoked to drive the evolution. The solar passive qualities of the object under study allow the energizing evaluation. This paper deals with the interaction between verbal thinking and visual thinking through the use of this generative tool.

title	I think Therefore i-Phone: The influence of Pervasive Media on Collaboration and Multi-Disciplinary Group Work
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. 69-84.
summary	The study of value and its transfer during the multi-disciplinary process of design is stable fodder for research; an entire issue of Design Studies has been devoted to Values in the Design Process. By scrutinising design meetings Dantec (2009) and Ball (2009) separately examine the mechanisms of value transfer between the agents involved in design (clients, designers, engineers). Dantec suggests this is best understood in terms of requirement, values and narrative; Ball proposes it should be viewed as a combination of "analogical reasoning" and "environmental simulation". If we look at Vitruvius and his primary architectural manual (Pollio 1960) we find values‚Äîin the form of firmitas, utilitas and venustas‚Äîembedded in this early codification of architectural practice. However, as much current research is restricted to design practice what occurs when value frameworks move between domains of cultural activity (such as design to construction and vice-versa) is not privileged with a comparably sizable body of research. This paper is concerned with the ongoing usage of pervasive media and cellular phones within communications and value transfer across the disciplinary threshold of design and construction. Through participation in a building project we analyse the subtleties of interaction between analogue communication such as sketches and digitally sponsored communication such as e-mail and mobile phone usage. Analysing the communications between the designer and builder during construction suggests it is also a creative process and the distinctions between design and construction processes are complex and often blurred. This work provides an observational basis for understanding mobile computing as a dynamic ‚Äòtuning‚Äô device‚Äîas hypothesized by Richard Coyne (2010)‚Äîthat ameliorates the brittleness of communication between different disciplines. A follow up study deploys ‚Äòdigital fieldnotes‚Äô (dfn) a bespoke iPhone application designed to test further suppositions regarding the influence exerted upon group working by mobile computing. Within collaboration individual communiqu_©s have different levels of importance depending on the specific topic of discussion and the contributing participant. This project furthers the earlier study; expanding upon what mobile computing is and enabling us to infer how these emergent devices affect collaboration. Findings from these two investigations suggest that the synchronous and asynchronous clamour of analogue and digital tools that surround design and construction are not exclusively inefficiencies or disruptions to be expunged. Observational evidence suggests they may provide contingency and continue to have value attending to the relationship between static components‚Äîand the avoidance of failure‚Äîwithin a complex system such as design and construction.

title	A Multi-dimensional Exploration of Urban Attributes by Data Mining
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. 333-350.
summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title	Reciprocal relationship of conceptualization and design problem definition: A proposed approach for an architectural design studio
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 410-422
summary	This research paper proposes an approach to be applied in the design studio. The proposed approach highlights the reciprocal relationship between concept articulation and design problem definition in a design method that exposes different design activities related to this relationship. The design method was applied in a design studio of an intermediate level. The study reports the analysis of student designs in terms of the deign method employed. Moreover, a survey was carried out in order to measure the responses of students and instructors regarding the design method and its approach. The main structure of the design method proposed can be described as follows: although the relationship of concept articulation and design-problem definition are reciprocal, the influence of one direction can be distinguished more than of the other direction on different design activities. The research using qualitative and quantitative methodologies analyzes the results and outputs of the theoretical investigations, the practical application in the design studio, and the questionnaire responses through different methodological tools.

summary	This paper discusses the issues involved with the introduction of the storyboard and the animatic in a design studio exercise. Storyboards - sketches used in film planning -, and the animatic - basically a moving storyboard - allow the student to understand space within in the context of a narrative. The purpose of the exercise was to enable the expression of subjectively experienced space in an early stage of urban context analysis. Differently than the traditional approach to animation which results a camera traveling through a path, the exercise approached animation from the perspective of the stories about the place.

summary	We investigate the recent coincidence of rapid global urbanization and unprecedented formal freedom in architectural design and ask whether this coincidence is an uneasy one. To study an extreme case of the new exotic geometries made possible through CAAD, we employ algebraic surfaces to experimentally design architecture in an university-based research and experimental design project. Such surfaces exhibit unprecedented complexity and new geometric and topological features yet are highly sound and harmonious. We continue and extend our research presented at the eCAADe 2009 conference in Istanbul.

title	Gis in Architectural Education: Design as a place-making process
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. 393-407
summary	Responsiveness to site conditions and environment is one of the axioms of architectural design. However, most students’ design is made in a non-geo-coordinated cyberspace through CAAD design and thus leading to “flying” proposals” that are not attached to the context. GIS teaches students in architecture to initially refer to real locations as the space in which they design is geo-coordinated and provides the wider context of the project. Along the design process, the project surroundings from macro scale; that is the globe, to the micro-scale that is reflected in the existing buildings, the road network and the topography are constantly present. At the end stage, the project is seen not as a free standing building but rather as an integral part in a real place on Earth. The 3-D urban visualization gives the possibility of evaluating the degree of success of place-making and the fitness of the project to its context. The aim of the paper is to present how a GIS course can support CAAD and improve the architectural design process as well as the quality of the design output towards a contextual architecture. The paper is based on the experience of the author who is architects and urban planner, in teaching design studios and Urban Planning based on GIS as an elective course to graduating students in architecture at the University of Bahrain. It presents an alternative method that is called Permanent Presence of the Real World PPRW.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 314-327
summary	This paper explores an interdisciplinary design approach for coupling semi-automated applications with tangible user interfaces. It describes communication methods based on parameters and diagrams, between computer scientists and urban, architectural professionals and the matching abilities to give meaning to the various parts and elements of the system. By means of the development of two rule based applications it exploits different degrees of automation and kinds of feedback possibilities and its impact on discourse and decision making. It discusses design methods for interactive urban planning applications, which integrate the different requirements and benefits from both disciplines.

doi	https://doi.org/10.52842/conf.caadria.2009.285
summary	Schools and teachers increasingly apply Online Learning Environments for teaching and course management. In many cases, an existing platform is used to support the curriculum. At the K.U. Leuven in Belgium a campus-wide platform is provided, using a commercial Content Management System. At the same time, the Design and Building Methodology research group at the Department of Architecture, Urbanism and Planning developed a custom portal to organize Computer Aided Architectural Design courses and seminars. Integration of this portal into the university system was rather disappointing, since much of the flexibility and customizability was lost, without any chance of filling in the gaps. This article discusses the possibilities and limitations of existing web-based systems to support Computer Aided Architectural Design teaching and reports on our own experiences from the last decade. A comparison of selected systems is juxtaposed with the requirements derived from these experiences.

title	Architectural design analysis, historical reconstruction and structured archival using 3D models: Techniques, methodology and long term preservation of digital models
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 119-132
summary	With the increased usage of 3D modeling, visualization, simulation and Building Information Modeling, architects produce 3D models, both for new designs and for historic reconstructions. However, these models are seldom shared to transfer structured information about the project. Even if they are exchanged, they are often not usable outside of their original design application. Additionally, digital archives with architectural content can not easily provide structured information about these 3D models, limiting their usefulness. This article discusses an approach to provide better structured models, using a combination of a sound methodology, the application of open file formats and additional metadata creation.

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	Computer-Aided Design (CAD) has become more and more part of the common architectural practice. Some designers have explored (in the past) different aspects, especially formal ones, allowed by these new information technologies. This paper’s goal is to explore the invention that would be specific to this new architectural practice. The hypothesis is to go back to the specificity of the image and to examine its evolution. This analysis will be done with reference to the « cycle of images » of the French philosopher Gilbert Simondon, described by means of stages and levels. This particular way of thinking will allow us, besides an overview of all those images in a genetic diagram, to reveal what can enable the passage from one level to another. We call this : “invention”.

summary	The Cooperative Design Environment Laboratory (CoDE Lab) is carrying out a research with students, trainees and seniors who have previously participated to CAAD-assisted design courses. These courses were developed with the aim of making participants independent from the pre-analytical phase project to the renderings of the final artifact. The programs that have been used so far are Autodesk Revit, Graphisoft Archicad and Nemetschek Allplan.The teaching workgroup has always believed that analyzing, deconstructing and reconstructing the architecture teaches much in terms of understanding. If the process is done correctly, it entirely re-traces the creative dynamics developed by the original designer. Subsequently, the educational practice is to choose a notable architectural work, designed and/or created by a Master of architecture, and to reproduce it in all details: aesthetical-formal, morphological, technological, structural, modular, etc. The final result is an archive of well-developed reconstructed models of great specific interest. The students on the other hand thoroughly learn how to control the tools and all BIM planning procedures.
