title	Some Phenomena of Analogical Thinking in Design
doi	https://doi.org/10.52842/conf.caadria.2009.781
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 781-790
summary	Analogy has been ascribed a key role in architectural design. Until now, there has been no complete theory describing how the analogical thinking process works in the design domain. Analogical thinking usually relates to freehand sketches and rarely connects to computer media. This research attempts to investigate analogical thinking from the perspective of the conventional media and computer media. Four analogical thinking in design phenomena have been established.

title	Spatial and Temporal Sequence: Film, animation and design theory - toward a constructed morphology
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. 165-176
summary	This paper presents an investigation of film, space, form and motion to expose issues of spatial perception. The objective is to use a brief moment of constructed moving imagery (a film scene) as the vehicle to develop a spatial/temporal sequence. The design research focuses on an examination of the procedure or process constructed by the director/cinematographer. The changing position of the camera continually changes the relationship of the frame to the viewed context. The project asks the student to interpret the spatial and temporal transformation, through the continual oscillation between foreground and background, in an effort to unravel the pretext of the singular point of view to reveal the intention of the filmmaker. The project discussed here focuses on a relationship between the projection of space in architectural representation and the production of space through complex geometries relative to temporal discontinuities and the way in which they agitate and alter one another. Drawing topological relationships between of the paths, or trajectories of movement, within a proposed scene of a film is the vehicle for investigation in this project. An event or configuration complete in itself, but forming part of the larger collection, is modelled and transformed to suggest various structural and temporal definitions with respect to spatial portrayal through the composition of time and the cinematic frame. In particular, spatial animation of a sequence of framed condition was to be explored in the development of a spatial episode.

summary	In recent years a number of projects have been emerged, in which the new possibilities of the computer as a design tool, have been used. Through the digital chain from design to manufacturing the efficiency has increased and allows the implementation of complex architectural structures. With all these new opportunities, also new challenges arise in the teaching and the educational concepts. The paper describes the detailed course concept and the didactic strategy using the example of a parametric designed roof structure, we designed, planed and build up in scale 1:1 within the main course. „Wendepunkt\|e im Bauen“ (Turning point\|s of building) is the name of an exhibition at the “Pinakothek der Moderne” in Spring 2010. In addition to contributions of the industrialization in the building industry from 1850 to the present day, the exhibition also serves as a platform, to demonstrate new possibilities of computer-aided parametric design and the closely related computer aided manufacturing (CAM). In this context, we took the chance to build a sculpture in Scale 1:1 to show the potential of a constant digital workflow and the digital fabrication. Through the digital chain from design to manufacturing, the efficiency has been increased by the computer and allows the implementation of new complex architectural structures. But the efficiency of the high-degree-automation through the use of computerized machines usually ends in the production of the components. Because this coincidence of the elements in the assembly often proves cost and time, the aim of the project was to optimize both, the production of components and their assembly as well. As part of the wintercourse 2009/2010 different aspects of automation have been reviewed and new solutions have been analyzed. Together with 15 students of the Faculty of Architecture the complete digital chain started with the first design ideas, about parametric programming through production and assembly had been researched, implemented and brought to reality. In the first steps, the students had to learn about the potential, but also about the problems coming with the digital-design and the attached digital-production. There for the course took part at our computerlab. In weekly workshops, all ideas have been implemented and tested directly in the 3-dimensional parametric model. And thanks to the interdisciplinary work with the Department of Structural Design also static factors had been considered, to optimize the form. Parallel to the digital form-finding process, the first prototypes have been produced by the students. By using the chairs 3D-CNC-Mills we were able to check the programmed connection detail in reality and apply the so learned lessons to the further development. After nearly 3 month of research, designing, planning and programming, we were able to produce the over 1000 different parts in only 4 days. By developing a special pre-stressed structure and connection detail it was also possible, to assemble the whole structure (13.5m x 4.5m x 4m) in only one day. The close connection between digital design (CAD) and digital manufacturing (CAM) is an important point of our doctrine. By the fact, that the students operate the machines themselves, but also implement projects on a scale of 1:1, they learn to independently evaluate these new tools and to use them in a meaningful way.

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.

summary	Public transport interchanges often involve several stakeholders for planning and decision-making. As a result complexity leads to inefficient processes, leading to indecision, disruption, or costly delays. Consequently, the paper focuses on the application of tools for navigation and prioritization of opportunities in the need finding, fuzzy-front end, or mystery phase as introduced by Martin (2009). The paper outlines in a case study how a multi-stakeholder platform can progress from complete ambiguity in project definition through to clearly defined and understood projects that have a shared intent across the multi-stakeholder platform. These tools have been applied in a public transport context, by demonstrating the process of integrating digital innovation into various stakeholders through a participatory research process. The paper introduces the research background; discusses the hypothesis; outlines the case study; emphasizes its significance for multi-stakeholder decision-making and discusses the opportunities for the built environment.

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.

title	Fotografia digital e imagens multi-perspectivas no estudo de sítios históricos [Digital photography and multi-perspective image in the study of historical sities]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The creation of panoramic images for depicting urban landscape is a technique that has its origins in Antiquity. These images, which are known to represent large urban areas from multiple views, can be considered true works of art. Recently there has been a growing interest by some researchers, especially in the area of computer graphics, in the production of multi-perspective images for representing historic sites. However, the focus of these studies has been especially the computational aspects of this process, and there are few studies that address the impact and possibilities of these methodologies in historic preservation and urban planning. Realizing this shortcoming and considering the demand for a perspective more connected to cultural heritage, our proposal is to associate the excellent visual results of the multi-perspective images to the rich possibilities of computer simulation that can provide digital photography. The fact is that in recent years we have experienced technological innovations in the field of computer simulation that far exceeded our expectations. While most surveys of buildings are still based on the use of tape measure, pencil, paper and camera, the computer has become increasingly the main interface between the user and the information and is now the preferred instrument for the production and viewing of images, including the creation of virtual environments. Thus, this work seeks to explore the great potential which seems to exist in the combination of digital photography and the technique of multi-perspective image representation, which may provide new approaches and perspectives for the field of historic preservation. For that, we present a rapid and low cost methodology, developed in recent years, which generates orthophotos and metric multi-perspective images, useful for the analysis of built heritage and historic sites. In addition to that, we will also discuss further possible byproducts of this methodology, among which we could highlight the creation of three-dimensional models, and the analysis of building pathologies in combination with thermal photography. As a case study, we will present a representation of the Rua dos Caetés, a listed historic district in Belo Horizonte (MG), Brazil.

title	Testing the relevance of parameterization to architectural epistemology
source	Architectural Science Review, Volume 52.2: 135-141
summary	Advances in building information modeling (BIM) deeply impact the production of new architecture; its benefits are obvious and its acceptance widespread. But how does BIM impact the study of existing architecture? Can BIM be assumed to operate as a neutral framework, equally applicable to the study of architecture anywhere? Using as a point of departure a recent outline of the conceptual structure of parametric modeling prepared by Sacks, Eastman, and Lee (2004), this paper compares parametric models of two existing works of architecture: Mies van der Rohe’s Crown Hall and Peter Zumthor’s St. Benedict Chapel. The processes of parametrically modeling each building are specifically compared in two ways: first, parameters are established for each model; second, each model is "flexed" as a means of disclosing possible semantic relationships within each work of architecture. Because each building demands a different parameter-establishment strategy, and because the models permit different degrees of flexibility, the comparison illustrates the shortcomings of a "neutral framework" assumption to an architectural epistemology.

summary	The paper presents a framework for parametric and generative design based on shape grammars, implemented inside a 3d animation tool. A simple description is given on how animation works, along with parity features between shape grammars and animation tools. Work covered in previous papers by the writer, namely how the designer constructs individual tools from simple animation mechanisms is here expanded in a framework of algebras that not only function in geometric dimensions but also in time.

summary	The introduction of Rapid Prototyping technology such as 3D printers and diverse Numerically Controlled machines such as laser cutters and milling machines, has made it obvious for many educational institutions, that a paradigm shift is occurring these years, that will forever change the design- and architectural practice, - for better or worse. This paper discusses the current change of role and status of the representation as a means to communicate design in the digital era. It outlines two opposite directions for the development of software technology, and brings forward previous and current research, on the didactic aspects of introducing digital software into the curriculum of architecture and design education. The paper describes a workshop held at the Danish Design School, where students proficient in using digital media, were challenged to use analogue models instead, to rediscover and utilize some of the creative potentials offered by this medium. Two other workshops discussing similar themes with different foci and different participants have been held since. One hosted by the Glass & Ceramic School on Bornholm, where the students are trained as traditional Craftsmen and another hosted by Nordes2009 at AHO in Oslo, where the participants came with a background in the research community. My own research interest lies in establishing or refueling a discussion on the importance of the ambiguity in a physical representation, as opposed to the finite interpretations offered by the digital modeling environment, that the profession is accustomed to work within. This interest has recently been confirmed and renewed by reading “The (soft) Architecture Machine(s)” from 1970+75 and by studying the works of Professor Julio Bermudez and Professor Bennett Neiman.

summary	This paper compares the musical and architectural languages exploring the similarities between works related to Twelve-tone music and Descontruction. To do this, first looks at Opus 27 by Anton Webern whose goal was to explore the spatiality in the context of sound perception by using a topology based on a square matrix of twelve rows and columns. Next, compares these procedures to those adopted by Peter Eisenman to design the conceptual model Guardiola House (1988), demonstrating the affinity between spatial and temporal constructions in the works of these two authors.

summary	This paper discusses an educational approach emphasizing the changing role of mathematics and potentials of mathematical thinking in architectural education on the course of changing design paradigm: from designing the product to designing the process. In this context, randomly selected samples of student works, realized within the context of an elective undergraduate course, Arch 333 “Mathematics in Architecture” at Middle East Technical University, Ankara, Turkiye are presented. It is shown that mathematical thinking provide not only to science people a solid ground for further explorations, but also new inspirations to people involving art and design and help them to overcome prejudices and fears related with mathematics in their minds. It is believed that this approach encourages them to discuss complex problems with meta language of mathematics and develop ability to consider the design process as a whole.

summary	The way screens are attached to architecture at present limits architectural surfaces to carriers of signs. The research presented in this paper offers a possible solution that allows architectural surfaces to be both a space-defining element that has certain architectural material qualities and at the same time allows media technology to be embedded. These surfaces can alter their state from static material to dynamic image in an instance. The paper presents a prototype capable of fulfilling this requirement. It also positions the research within the architectural discussion by comparing it to works of others and confirming its research value by reference to work in a similar direction. Finally, the paper evaluates the research and concludes that it could offer a ‘fabric’ to be used as a sort of media clothing for architecture in the electronic age (Ito, 2001).

summary	Genetic algorithms categorized as global search heuristics are search technique of seeking approximate or exact solutions for optimizing problems. Our generative tool named notchSpace starts from a population of randomly generated individuals which rationally subdivide architectural spaces with a low “fitness”. During generations’ evolution, the population is recombined, modified and mutated at a low rate to form new modes of building spatial subdivision; a new population is used in the next iteration. NotchSpace works up a research platform to evolve architectural spaces, and it explores the thinking of translation from computer algorithms to the field of architecture.

title	Calculating Visual Complexity In Peter Eisenman’s Architecture

summary	This paper describes the results of the first computational investigation of characteristic visual complexity in the architecture of Peter Eisenman. The research uses a variation of the “box-counting” approach to determining a quantitative value of the formal complexity present in five of Eisenman’s early domestic works (Houses I, II, III, IV and VI all of which were completed between 1968 and 1976). The boxcounting approach produces an approximate fractal dimension calculation for the visual complexity of an architectural elevation. This method has previously been used to analyse a range of historic and modern buildings including the works of Frank Lloyd Wright, Eileen Gray, Le Corbusier and Kazuyo Sejima. Peter Eisenman’s early house designs–important precursors to his later Deconstructivist works–are widely regarded as possessing a high degree of formal consistency and a reasonably high level of visual complexity. Through this analysis it is possible to quantify both the visual complexity and the degree of consistency present in this work for the first time.

title	When is Generative Design Design?

summary	The question in my title is neatly put in a counterfactual: HOW WOULD CALCULATING BE DIFFERENT IF TURING WERE AN ARTIST OR DESIGNER AND NOT A LOGICIAN? A generative process – in design or wherever calculating is tried – uses recursive rules. But RECURSION alone isnʼt design. EMBEDDING is needed, as well. This entails a switch from blindly following rules to seeing what happens. Then calculating in Turingʼs way by counting is a special case of calculating in an artistʼs or designerʼs way by seeing. And creativity as recursion – in logic, linguistics, and computer science – extends to art and design. Generative design is design if thereʼs embedding, that is to say, anytime thereʼs seeing. Usually, seeing is outside a generative process, when it stops and you look at the results. What recursive rules imply may not be what you see. But embedding works with recursion, so that rules let you see as you go on inside a generative process. Seeing starts anew – without stopping – every time a rule is tried. Recursion and embedding together make generative design design. This is summarized in a formula: GENERATIVE DESIGN + EMBEDDING = DESIGN // The equivalence is a useful heuristic for new research in calculating, and for art and design.

title	Refining the Computational Method for the Evaluation of Visual Complexity in Architectural Images: Significant Lines in the Early Architecture of Le Corbusier
doi	https://doi.org/10.52842/conf.ecaade.2009.689

summary	Past research over the last two decades has demonstrated that fractal analytical methods can be used to evaluate the visual complexity of architectural designs. Applying a computer program that has been developed specifically for the quantitative evaluation of architecture, the authors previously tested the fractal analysis method on several well-known architects’ works including those of Le Corbusier. However, while undertaking this research the computational method revealed unexpected results for the visual complexity of Le Corbusier’s early, highly ornamented, house designs. This paper examines these anomalous results and the proposition that they are a by-product of the data chosen for analysis. The fractal method relies on architectural drawings as raw “data” but little research has been undertaken into which elements should be chosen to represent the buildings or alternatively, which lines are “significant”. The present paper uses the results for ten of Le Corbusier’s house designs to examine the sensitivity of the method.
