Key, Sora. "A Computable Language of Architecture: Description of Descriptor Language in Supporting Compound Definitions." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 431-438. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Language is a particular kind of formal structure. It allows systematic approach to the subject matter for the speaker while providing an exploratory space to reason with. In this paper, we present a simple language that describes spatial qualities of architecture based on the geometry of built elements. We also provide a detailed description of the components and the structure of our language and show how one might construct compound definitions using the language. We then discuss the implication of constructing a language and how we can use it as a tool and research model in the study of architecture.
Ostwald, Michael, and Josephine Vaughan. "A Data-Cluster Analysis of Façade Complexity in the Early House Designs of Peter Eisenman." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 729-736. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Relatively few quantifiable and objective methods exist for the analysis of architectural elevations. Only one of these methods has been repeated by multiple researchers and used for the analysis of a wide range of historic and modern buildings and architectural types. In the present paper, the computational variation of this method-the fractal approach to determining characteristic visual complexity-is applied to the early house designs of Peter Eisenman. The results of this analysis are then subjected, for the first time, to cluster analysis in an attempt to uncover patterns in the way in which Eisenmanis houses are shaped by orientation, address and permeability. Such an analysis is of interest because Eisenman argues that he set out to design these early houses without regard for such factors. The paper concludes that the mathematical data generally supports Eisenmanis contentions regarding his Houses I, II, III, IV and VI.
Paio, Alexandra, and Benamy Turkienicz. "A Generative Urban Grammar for Portuguese Colonial Cities, During the Sixteenth to Eighteenth Centuries: Towards a Tool for Urban Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 585-592. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper main goal is to depict the generative principles of 16th -18th century Portuguese colonial urban design described from its Pythagorean-Euclidean geometrical genesis and correspondent logical rules and operations. These origins were found in Portuguese compendiums and treaties on practical geometry, architectural and military engineering from the sixteenth through the eighteenth century. The study attempts to show that rigorous operative geometrical discourse is inseparable from social knowledge, whereby form is the operative result of abstract mental processes and logical visual reasoning associated to ideas of growth and reproduction of order.
Arpak, Asli, Lawrence Sass, and Terry Knight. "A Meta-Cognitive Inquiry into Digital Fabrication: Exploring the Activity of Designing and Making of a Wall Screen." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 475-482. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The design process is observed in “self-reflection” by an experiment including visual computing, structure design, joint design, and assembly design.  The experiment is defined as the making of a self-supporting timber wall screen, which includes laser-cutting and rapid-prototyping. The reciprocal action between the visual and physical realms is observed through the design activity.
Matcha, Heike, and Gero Quasten. "A Parametric-Typological Tool: More Diversity for Mass Produced Single Family Homes Through Parametrized Design and Customized Mass Production." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 409-416. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. We present a research program in which a plug-in tool for the generation of vertically stacked single family homes is developed and implemented in the software Autodesk Revit Architecture. The parametrized typology will provide for more variety, individuality and appropriateness in the homes themselves and also in the urban structures created by them. CAAM methods furthermore drastically reduce the production costs. The research is government-funded and sponsored by the building and software industry with the aim to both extend the functionality of an existing software package and to build a prototype urban development.
Schneider, Sven, and Frank Petzold. "A Virtual Design Platform: Bridging Barriers When Designing with Computers." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 205-212. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The paper summarizes the results of a diploma thesis. Taking the potential of computers to be an ultimate design-medium as its premise, the thesis examines how to enhance the way we use digital design tools. It identifies central characteristics of the design process that need to be considered in a digital design environment. Based on a conception of design as a cyclic process involving appropriate design tools, the paper singles out usability, in the sense of ease of use of such tools, as a key criteria for overcoming problems associated with designing on and with the computer. Drawing on these considerations a prototype has been developed which attempts to bridge barriers between the use of different design tools using an existing software framework.
François, Guéna, and Caroline Lecourtois. "Aided Architectural Sketching with Markov Models: Dromies and Recognition." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 745-752. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This article presents the current state of an ongoing research project developed at the ARIAM-LAREA laboratory of the school of Paris La Villette. The aim of this research is to offer architects digital tools that allow them to explore the project with freehand sketches as they do with pencil and paper. The role of these tools is to interpret the freehand sketches in order to work on them and transform them. They produce from these freehand sketches a digital model from which it will be possible to build a 3D representation, or to evaluate the project from any technical point of view. This paper only shows the part of the system that recognizes particular strokes in an architectural drawing.
Krijnen, Thomas, Jakob Beetz, and B. De Vries. "Airport Schiphol: Behavioral Simulation of a Design Concept." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 559-564. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In this paper, we introduce an agent-based simulation of passengers in airport terminal buildings. A case study is described during which a prototype simulation tool is used to test the impact of a conceptual design change in an existing airport terminal building. We illustrate how this real-time, geometry-aware simulation can be generalized and integrated into the design process to support designers in configuring the spatial layout of public and functional buildings.
Barczik, Günter, Oliver Labs, and Daniel Lordick. "Algebraic Geometry in Architectural Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 455-464. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. We describe the exploration of the manifold novel shapes found in algebraic geometry and their application in architectural design. These surfaces represent the zero-sets of certain polynomials of varying degrees. They are therefore very structured, coherent and harmonious yet at the same time geometrically and topologically highly complex. Their application in design is mostly unprecedended as they have only recently begun to become accessible through novel software tools. We present and discuss experimental student design and research projects where shapes found in algebraic geometry were developed into pavilion designs. We describe historic precedents for the inspiration of art and architecture through mathematics and show how algebraic surfaces can be used to expand architectsi sculptural vocabulary, make the utmost of three-dimensional sculptural qualities, employ shapes that have a strong internal structure, transcend the imaginable and explore polynomials as a new kind of shape-making tool.
Gurer, Ethem, and Gülen Çağdaş. "An Emergent Form Generation Method for Supporting Conceptual Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 167-172. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Evolutionary design methodologies generally aim to present new form-finding processes, where nature-based approaches are used, such as self-organization, genetic algorithms etc. This paper aims to present a new architectural design approach that focuses on integrating these different evolutionary methods in an emergent process. The main goal is to achieve a high-level of integration where lacking qualities of each evolutionary method are completed by the other one in a synergic and especially emergent behaviour. A multi-level design approach is described in this study. Points highlighted are concerned with the pre-design phases. Within a bottom-top simulation, an infinite high-level solution cluster is revealed from behavioural interactions and collectivity of the low-level entities: agents. Simulated design process is visualized by a determined project area in Istanbul: Kuruçe_me Island on the Bosphorus as an exhibition center. Programmed in 3dsMax, simulation phase supports the creative design process in early phases.
Tredinnick, John, and Marion Harney. "An Interactive Tool for the Exploration of Contextual Architecture: Case Study: 18th Century Prior Park, Bath." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 623-630. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Situated on a southern hillside overlooking the World Heritage City of Bath in Somerset is the splendid 18th century landscape garden, Prior Park. The garden, now a National Trust property, has lost many of its original features and no longer affords the visitor the rich experience it once did. This project demonstrates how digital techniques can reconstruct a complex 12-hectare landscape and simulate the visitorsi pleasure of 250 years ago.
Carrara, Gianfranco, Antonio Fioravanti, Gianluigi Loffreda, and Armando Trento. "An Ontology-based Knowledge Representation Model for Cross-Disciplinary Building Design: a General Template." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 367-374. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Process/product complexity is at present an unavoidable component of present building design approach that affects building productis quality. To overcome this problem, effective collaboration is required among all the actors involved in the design process. Data and information exchange is not sufficient to guarantee mutual understanding, to support effective collaboration among actors, it is required a proper knowledge formalization and management. This paper reports on an innovative structure for knowledge modelling in cross-disciplinary building design, that has been formalized in a general template. The proposed Knowledge Model has been, at present, implemented by means of available ontology editors and is going to be used into teaching courses to check its efficiency in collaborative building design classes.
Beirão, José, José Duarte, and Rudi Stouffs. "An Urban Grammar for Praia: Towards Generic Shape Grammars for Urban Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 575-584. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper presents a shape grammar for planned urban spaces intending an implementation for generative urban design. This implementation will form part of an urban design support tool defined to formulate, generate and evaluate urban designs. The goal is to formulate urban program descriptions according to context conditions using a description grammar and generate alternative design solutions using a shape grammar. The generation is guided by several evaluation processes performed by an evaluation module. In this paper we are focusing on the definition of the generic shape grammar using an existent urban plan as a case study. The aim is to encode the design moves of the urban designer into generic grammar rules amenable for specific instantiations through the customization of rule parameters.
Dounas, Theodoros. "Animation as a Framework for Generative Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 213-218. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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.
Tong, Togan, Erdal Aydin, and Emre Pusat. "Animation vs. Simulation." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 803-808. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In his book “Cinema as an Art”,  Rudolf Arnheim states that cinema (art) cannot achieve to realize the mechanical reproduction of the real (nature) because of technical limitations but also states that these limitations are compulsory for the production of art. According to Arnheim, these limitations cause artists to interpret the real (nature) and to materialize impressive expressions. Architecture presents its productions to its viewers (customers) using some kind of media, before materializing them in the physical world. The most common ones nowadays are technical drawings (perspectives), models, photographs and computer aided models and animations. The architect makes impressive expressions based on the technical limitations of the medium he/she uses. With the computer technology, simulation gives possibilities to the architect for presenting and experiencing his/her art very close to reality. Simulation is the best way to reproduce the reality mechanically, when it is compared to other mediums. In this study, simulationis potential as an architectural presentation technique is examined through Arnheimis vision and Rembrandtis painting “Staalmeesters”.
Sorguç, Arzu, and Semra Selçuk. "Art and Literature as a Teaching/Learning Interface of Mathematics for Students of Architecture." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 465-472. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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.
Razali, Fairuz, Syed Zubir, Rashidah Rahman, and Wan Sulaiman. "Associative Architectural Design: the Potential of Land Economical and Ecological Factors in Determining Variations in Housing Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 181-188. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Capitalism does play a decisive role in the planning and generation of countless generic typologies in the urban landscape to a certain extent. This also includes the planning and generation of housing models. As a result of conventional planning that is based on “entrepreneurship subdivision”, only similar housing model for a specific income group is sometimes offered. In the long term, this kind of development occupies massive land, which is not suitable for sustainable growth and creates social segregation. This paper suggests an alternative approach of “associative design”. Parametric design software is utilized to generate the housing diversity. It aims to construct a population of housing units that together form a new neighborhood model based on the land specificity that emphasizes its economic and ecological factors.
Choo, Seung, Kyu Heo, Ji Seo, and Min Kang. "Augmented Reality-Effective Assistance for Interior Design: Focus on Tangible AR Study." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 649-656. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This article presents an application of Augmented Reality technology for interior design. Plus, an Educational Interior Design Project is reviewed. Along with the dramatic progress of digital technology, virtual information techniques are also required for architectural projects. Thus, the new technology of Augmented Reality offers many advantages for digital design and construction fields. AR is also being considered as a new design approach for interior design. In an AR environment, virtual furniture can be displayed and modified in real-time on the screen, allowing the user to have an interactive experience with the virtual furniture in a real-world environment. Finally, this study proposes a new method for applying AR technology to interior design work, where a user can view virtual furniture and communicate with 3D virtual furniture data using a dynamic and flexible user interface. Plus, all the properties of the virtual furniture can be adjusted using occlusion based interaction methods for a Tangible Augmented Reality.  
Frumar, Jerome, and Yiyi Zhou. "Beyond Representation: Real Time Form Finding of Tensegrity Structures with 3d 'Compressed Components." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 21-30. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Tensegrity structures are of interest to architecture and engineering as a practical means to explore lightweight and rapidly deployable modular structures that have a high degree of geometric freedom and formal potency. The notion of tensegrity structures with 3D “compressed” components is introduced and their feasibility is demonstrated through selected physical models. Attempts to further explore the architectural potential of tensegrity structures within a computational environment have proven difficult, as they are statically indeterminate and require form finding procedures to “find a geometry compatible with a self-stress state” (Motro 2002). An overview of tensegrity “capable” software that can be used for architectural design is followed by a discussion that introduces an additional computational method based on particle-spring systems. This approach enables real time manipulation of tensegrity networks. Two projects that utilize this unique tool are described.
Estévez, Alberto. "Biodigital Architecture." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 681-686. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The latest biological and digital technologies offer new possibilities and benefits for the production of new architecture: There is vast potential in the natural world if we work with DNA as though it were natural software, and in the digital realm if we work with software as though it were digital DNA. Pioneers in these fields converge in the Biodigital Architecture Masteris Degree, with the Genetic Architectures Research Group and Ph.D. Programme, at the ESARQ (Universitat Internacional de Catalunya), in Barcelona. The purpose of this paper is to put forward the theoretical basis and some of the research carried out to date.
Dounas, Theodoros, and Alexandros Sigalas. "Blender, an Open Source Design Tool: Advances and Integration in the Architectural Production Pipeline." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 737-744. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. We examine an open source 3d suite of tools called blender, as a tool for architectural design. The unique features of blender are examined in terms of ease of use and integrated nature since blender incorporates a simulation engine and a game engine that can be used creatively in the design process. The unique data structure of Blender is examined with the features and work flow that this structure brings in the design process.  Also a simple comparison is made between Blender and 3ds max in terms of features and workflow as visualization tools together with an assessment of a two year seminar that took place in the Department of Architecture, in Volos Greece.
Narahara, Taro. "Bottom-up Design Inspired by Evolutionary Dynamics: Adaptable Growth Model for Architecture." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 391-398. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Development of flexible and adaptable architecture has been a perennial theme among practitioners. Design of universal subunits that could tolerate technological, environmental, and circumstantial changes over time is a challenge. In this paper, I would like to introduce several generative design strategies inspired by ideas from evolutionary dynamics and discuss potential benefits of the methods for designs of emerging future building types.

In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 75-82. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009.

The overall economical benefits of Building Information Modelling are generally comprehensible, but are there other problems with the implementation of BIM as a formulized system in a field that ultimately is dependent on a creative input? Is optimization and economic benefit really contributing with an architectural quality? In Denmark the implementation of the digital working methods related to BIM has been introduced by government law in 2007. Will the important role of the architect as designer change in accordance with these new methods, and does the idea of one big integrated model represent a paradox in relation to designing? The BIM mindset requires changes on many levels.

Göttig, Roland, and Jörg Braunes. "Building Survey in Combination with Building Information Modelling for the Architectural Planning Process." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 69-74. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The architectural planning process is influenced by social, cultural and technical aspects (Alexander, 1977). When focussing on computer based planning for retrofitting or modification of buildings it becomes clear that many different data formats are used depending on a great variety of planning methods. Moreover, if building information models are utilized they still lack some essential criteria. It is rarely possible to attach individual data from survey systems. This paper will show both a way to add data from building survey systems as an example for special data attachment on IFC files and how to utilize content management systems for IFC files, deviated plans, lists of building components, and other data necessary in a planning process.

Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper reports on the development of the computational tool CloudNets that allows for the modelling and investigation of emergent relational phenomena and provides two worked examples of how the tool was used by architecture students within the context of a computational design seminar taught by the authors at RMIT University.
Pektas, Sule. "Cognitive Styles and Performance in Traditional Versus Digital Design Media." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 769-772. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper investigates the interactions between cognitive styles as measured by Ridingis Cognitive Styles Analysis and performance in traditional versus digital design media. An empirical research revealed that design performance in both media correlated with being at the Imager side of the cognitive styles continuum. The Wholist-Analytic dimension was found to be independent from performance. The Bonferroni tests indicated that the digital drafting scores of the Imagers were significantly higher than that of the Verbalisers, but no other significant relation was observed. The findings suggest that drawing with computers entails specific cognitive actions that may favour visual type of individuals.
Kozikoglu, Nilüfer, Meral Erdogan, Ahmet Nircan, and Fulya Akipek. "Collective Design Network: Systems Thinking (Event-Pattern-Structures) and System Dynamics Modelling as a Design Concept and Strategy." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 533-540. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper will relay the initial phase of a collaborative work within partners from the design discipline, systems engineering, and software engineering which deals with the interrelations of “network idea”,  “systems thinking”,  “collective design”,  and “computation”. Vensim-a-system dynamics modelling tool developed by Ventana Systems, Inc. in 1992 - has been used in an experimental first year design studio to engage students in systems thinking in the architectural design environment. It has been observed that this tool enabled most students to develop a multi-layered, complex and more controlled design logic and to amplify the cognitive processes at the beginning of the design education. We conclude that in order to fully realize systems thinking in the design process, new ways of integrating parametric design environments and system dynamic modelling environments needs to be investigated.

Aslan, Sema, and Gülen Çağdaş. "Comparison of Designers Modeling Approaches During Architectural Design Process." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 753-758. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This study has been started as a part of a research, related to exploring impact of novel interfaces during collaborative architectural design process on designersi way of thinking. However, in this paper it is intended to focus on how the input devices reflect on designersi modelling behaviour in computer environment. Therefore it is intended to compare designeris modelling approaches in computer environment via a case study. Four master students in architectural design computing graduate program have attended to the case study. The findings of the case study is presented and evaluated in the discussion section.
Montenegro, Nuno, and José Duarte. "Computational Ontology of Urban Design: Towards a City Information Model." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 253-260. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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.

In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 97-104. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper presents a framework for modelling the way that designers interpret their world during design activity. Designers interpret the world through their expectations. Expectations are derived from situation. Agents form concepts in situations and use concepts in situations. A model of concept formation based upon a geometric representation of conceptual space is described. In the model, expectations are constructed from memory within a situation. In interpretation, the world is made to look like expectations. Some preliminary explorations with an implementation are described.

Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Generative tools are used to generate rapid products and they support mass customization. These properties are mostly needed in the case of an emergency when rapidity in design and application means much more than anything else. Shipping containers are used in different projects as well as sheltering and housing projects. It is a standard module which can be used as a basic module in the sheltering projects. Small modifications are sufficient, which helps it being a rapid application. In this paper a generative tool named Container PoDS which using shipping containers as basic module for post-disaster sheltering is introduced.
Fleischmann, Moritz, and Sean Ahlquist. "Cylindrical Mesh Morphologies: Study of Computational Meshes based on Parameters of Force, Material, and Space for the Design of Tension-Active Structures." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 39-46. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In experimenting with digital processes for simulating the behaviour of tension-active cable nets, a method was developed for creating informed geometries by utilizing computational meshes that carry properties of structure, space, and material. A spring-based particle system provided the dynamics to simulate the flow of tension force through the geometry. Particular functions were scripted to embed logics for fabrication and analysis of spatial parameters. This formulated a lightweight, reactive design tool for which multiple cable net morphologies could be quickly generated. This paper will describe the experiments in creating the method to generate such cable net morphologies, and discuss the potential application for this computational framework to apply to other architectural systems.
Sönmez, N.Onur, and Arzu Erdem. "Design Games as a Framework for Design and Corresponding System of Design Games." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 119-126. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Borrowing from Wittgenstein, we devised a concept of “design games”, for a better understanding of the design process. A design game is the elusive basic unit of a design process. When we characterize design process with blurry components and indefinite stages, we can model design as a complex, collaborative process, where the designersi biological states lose importance. This approach, may give rise to a better conception of design, where human-human, human-machine, machine-machine, or process to process interactions are inevitable, thus a thorough framework of collaboration might be defined. Moreover, if we start from this conception to produce a design framework, we may obtain a model for design automation studies. The loose pattern of design games, when combined with the possibility of all the agentsi being non-humans, seems us to indicate the road to "creative design automation".

In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 305-312. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper represents an educational practice aiming at analysis of the link between digital design and digital manufacturing. CFD (conception, fabrication, digitale) is a one week workshop with graduate (master recherche) students of architecture school of Nancy. Having passed the first semester with a focus on modelling principles, computational logics and formal data representation, students are well prepared to apply them all in the process of form generation. The exercise is based on experimenting with new approaches in computational form generation interweaving geometry, aspects of construction and fabrication technologies.

In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 673-680. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Digital Architectonics is a term which refers to the application of digital technology to the architectural design process. This paper presents a new Digital Architectonics software tool, which allows various methods of 3D modelling, formfinding and optimization to be combined to generate and develop concept- and scheme-design options. The practical use of the software is demonstrated through the case study of the recent architectural competition to design a new hothouse for the Aarhus University Botanical Garden.
Delaveau, Anne-Sophie, François Guéna, and Caroline Lecourtois. "Digital as a Tool/Reference for Architectural Conception: Examples from Two Agencies: Ateliers Jean Nouvel and Jakob+MacFarlane." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 197-204. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper aims at specifying how “digital” acts in contemporary architectural design. On that purpose, and in an a priori manner, we will formulate hypotheses of concepts able to translate the specificities of digital design. In this research paper, we beg the question that the “digital culture” may influence the architects in two manners: in design operation and in references. The conceptual tools will be given by architecturology, and our hypotheses will be illustrated with examples of two French firms (Ateliers Jean Nouvel, Jakob+MacFarlane).
Brell-Cokcan, Sigrid, Martin Reis, Heinz Schmiedhofer, and Johannes Braumann. "Digital Design to Digital Production: Flank Milling with a 7-Axis CNC-Milling Robot and Parametric Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 323-330. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Just recently Flank Milling has opened up new possibilities in detailing large-scale architectural building envelopes. Whereas examples such as the Hungerburgbahn by Zaha Hadid show the application of Flank Milling at the end of the architectural manufacturing process, our research, in contrast, focuses on the implementation of constraints immanent to manufacturing techniques as early architectural design parameters. This process is explored by the help of generative modelling tools, to allow an intuitive design of freeform parametric curves and surfaces while at the same time obeying crucial geometric conditions. In this paper, we will focus on the “digital design to digital productioni process on a 7-axis industrial CNC -robot.
Lyon, Eduardo. "Digital Fabrication and Component Optimization Using DFM: Integrating Two-dimensional Cutting and Three-dimensional Milling in Wood Panel Fabrication." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 565-572. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This research explores new ways to integrate manufacturing knowledge in to design phases. Through the use of design for manufacturing (DfM) concept, and looking at relations between its potential application in component design and its implementation using digital manufacturing technologies, the author implemented a DfM model that varies from previous models by incorporated learning in the process. This process was based on, a knowledge systematization process, and the incremental development and refinement of design heuristics and metrics. Subsequently the attempt on this research is twofold. One is to realize a process to capture and organize manufacturing knowledge, and second to organize that knowledge and make it available as a DfM model for component design using specific CNC technology.
Sokmenoglu, Ahu, and Sevgi Türkkan. "Digital Monumentality in/for Public Spaces." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 835-842. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009.

Aim of this paper is to discuss the paradigmatic changes in the conception and production of “monumentality” through the transition from analog to digital forms of communication, design and production. Before looking for a correspondence to “monumentality” in the digital era, the basic concepts that define “monumentality” like aesthetics & public space will be theorized and discussed briefly. We will be questioning via examples, whether the classical conception and production of the “monument” still pursues in the digital era or if the digital revolution is able to alter the chemistry of it.

Cardoso, Daniel, Avni Argun, Carlos Rocha, and Jose Gonzalez. "Drawing Transparencies: 'Responsible Responsiveness' in Spaces Through Organic Electrochromism." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 83-88. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. A system for using organic polymers as electrochromic components for a buildingis facade is proposed, and early prototypes are presented. The potentialities of such system, Croma, are considered in two aspects: a) as interactive facades that change opacity in reaction to touch -hence “drawing with transparency”- and b) as elements to automate energy-smart behaviours of a building. Some implications are discussed.
Kocaturk, Tuba, and Ricardo Codinhoto. "Dynamic Coordination of Distributed Intelligence in Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 61-68. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Recent introduction and coupling of digitally mediated design and production environments facilitated a radical deviation from the traditional ways of using representations, knowledge assets, organizational forms and standards. Consequently, we observe an abundance of the traditional views of design and the emergence of new cognitive models/constructs based on the emerging relationships between the designer, the design object (artefact), the design tools/systems and the organizational network of the various actors and their activities in building design & production. The paper reports on the initial findings of an ongoing research which aims to uncover the ways in which digitalization and digital tools have recently been adopted to the work practices of multidisciplinary firms and the evolving socio-technical networks and organizational infrastructures within architectural practice.
Gholipour, Vida, Jean-Claude Bignon, and Laure Guimaraes. "Eco-Models: Modeling of a Digital Tool to Design Sustainable Buildings." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 551-558. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The demand for up-to-date information and design “tools” to help architects design more sustainable buildings is rapidly expanding. This demand has led to use various ecological assessment tools as support tools for the design process. The absence of adequate tools, which contribute to early stages, as well as the additional costs of tardy modifications, has led us to propose an eco-design support tool. This tool is based on a methodology named “Eco-Model (EM) Methodi that focuses on the ecological approaches of a building. This method proposes to consider environmental friendly solutions from the first sketches by proposing a number of micro-solutions, called here Eco-Model or “EM”. Subsequently, the study presents the first contour of software based on an EM approach. Thus, the various actors of the design team will be able to browse the useful information for their green projects and so collaborate to optimize the building design.
Li, Andrew I. - Kang, Liang Chen, Yang Wang, and Hau Chau. "Editing Shapes in a Prototype Two-and Three-dimensional Shape Grammar Environment." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 243-250. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Recently we developed a prototype general shape grammar system, called Grammar Environment (Li et al. 2009). It differs from other systems in that it aims to support designers who design with shape grammars. One task of such a system is to support users in editing shapes. The guidelines that we followed in developing Grammar Environment suggested that the shape editing system should both be integrated into the system and be powerful as a drawing tool. This seemed to be contradictory. We decided to make two shape editors: one stronger on integration, the other on drawing power.
Wang, Chung-yang. "Effect on Architectural Representation through Dynamic and Static Design Methods." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 497-504. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. For accelerating the birth of architectures, people apply logical inductions and definitions to design processes ambiguous in the past then explore the possibilities of design methods. Evolving with times and varied perspectives, there are gradually increasing ways which could generate the difference of the natures in architectures - dynamic or static. Architecture has its own mode of dynamic or static representation in every era. Many studies have pointed out this variation derives from the advances of design media, but there still apparently lacks studies focus on the relationship between design processes and architectural representation. Thus, this research aims to juxtapose design methods with dynamic and static representation in architecture then summarize the possible correlation between these factors.
Sarhan, Ahmed, and Peter Rutherford. "Embodied Game Agents in Environmental Design Education." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 795-802. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Over time, design instructors have become more encouraged to accommodate the play metaphor in their courses, for its rich technical and psychological assets. While there are issues regarding the interactive narrative structure of the game, embodied Multi-Agent-Systems (MAS) have been introduced to address these issues and handle complicated game objectives. With the ever-growing complexity of design concepts and the mounting demand to design for sustainability, more variables and intricacies are introduced to the design and decision making process. This paper presents a proposed method that utilizes MAS in game engines to resolve the environment design complexity for design students and untrained professionals. This method offers better comprehension of the implication of data generated from building analysis tools, and presents guidelines to develop the proposed design accordingly.
Asanowicz, Aleksander. "Evolution of Design Support Methods - from Formal Systems to Environment." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 817-824. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In the paper the main stages of the evolution of aided design methods (which led to the formation of new spaces of creation) will be presented. The first way in which human tried make his work easier were direct introduction of scientific researches in practice. Comprehension and studying the structure of design process creates real conditions for increase of its efficiency. Thanks to methodological researches the systematic design methods were developed. The next steep was introducing the IT technologies into the design process. Firstly as a simple tool, and after as the participant of the creative process. Last years an idea of “direct designing” - the use of VR as an environment for the spatial forms creation was elaborated. The environment starts to play a role of an active mediator joining the real world, the men and the computer. In this environment the designer has access to the processes and sources of creative activity. The qualitatively new process of architectural designing arises.
Karzel, Rüdiger, and Heike Matcha. "Experimental Design-Build: Teaching Parameter-based Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 153-158. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. We present a student design class, in which experimental full-scale parametric objects are planned and built. The class explores the possibilities of digital production chains in which CAAM techniques driven by parametric modelling can expand the range of possibilities for designing and producing architecture. We show how those possibilities and techniques can be integrated into architectural education in facilitating a transition from digital design to actual object. The didactic challenge represents teaching a methodological approach towards parameter-based design, its transfer into a software program and the choice of construction and production method.
Selçuk, Semra, and Arzu Sorguç. "Exploring Complex Forms in Nature Through Mathematical Modeling: a Case on Turritella Terebra." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 665-672. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Changing paradigm of nature-architecture relationship has being directly affected from developing science and technologies as well as from the impact of biomimetic inventions in various man made designs. Our perception of forms and structures are also shifting through use of computational techniques. From this aspect, mathematical models can be considered as the first step to analyze the complex forms and structures in nature. In this paper it is aimed to initiate a platform in architecture which will serve for discussions to explore the potentials of these interactions under the impact of computational and information technologies, not only in terms of formal/visual way, but also extending to learn more about the formation process in nature.
Fioravanti, Antonio, and Gianluigi Loffreda. "Formalizing and Computing Ontologies to Speed up the Construction of Knowledge-based Collaborative Systems: Three Different Approaches." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 341-348. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Architectural design is a purpose-oriented collective process defined in time, split up into phases, carried out directly or indirectly by numerous professional profiles and characterized by the co-presence of numerous disciplines and specialist skills. The efficiency of a shared design among multiple designers depends on how much the actoris semantics of the used terms are interpreted correctly by all the other actors involved in the design process without misunderstandings. The chosen way to find an answer to these questions is the development of a Collaborative Architectural Design system based on Knowledge formalized by Ontologies. An ontology has been implemented using three different approaches to define an entity based on Lisp, Protégé and Altova.
Lorenz, Wolfgang E.. "Fractal Geometry of Architecture: Implementation of the Box-Counting Method in a CAD-Software." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 697-704. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The author describes the basic principles for measuring architecture from the point of view of Fractal Geometry outlining the principle connections between Fractal Geometry and architecture, giving some examples and explaining the Box-Counting Method, which is an easily manageable method that can be applied to elevations. The paper not only deals with problems arising from using the Box-Counting Method but also with its relation to visual perception. It shows how the Box-Counting Dimension DB of façades can be measured with the help of a software program that was written by the author and has been implemented into AutoCAD. Finally, results of different configurations are given for the Koch curve and Robie House by Frank Lloyd Wright, showing the accuracy of this measurement method.
Sprecher, Aaron, and Paul Kalnitz. "From Formal to Behavioral Architecture: Few Notes on the Abstraction of Function." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 161-166. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. With the advent of information theories, contemporary architecture is approached in terms of the energetic formations of memorization, association and connection. The former architectural diagram becomes a concretization, an instance, one possibility, of an operational code. Memorization refers to the ability of architecture to embed information within the deepest composition of matter. Architectural performance has always been revealed by the integration, or association, of multiple parameters. Connections are vectors which fuse the knowledge of heterogeneous symbiotic human environments. In the “C-chair”,  a project by our laboratory Open Source Architecture, abstract objects such as points, lines, and surfaces act as memorizers of information. As the codified system reacts to external forces, an association of two distinct graph structures is developed and connections are formed as the architectural object emerges.
TalaÅ¡ová, Zuzana, and Henri Achten. "Fuzzy Rule Bases as a Tool of the History of Architecture: Application to the Analysis of Villas Designed by Adolf Loos." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 705-712. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This article explores possibilities of using fuzzy models as a new research tool in the history of architecture. Namely, Adolf Loosis villas are studied using these models. Fuzzy expert models will be used to analyze the principles of Adolf Loosis work. Rules applied by A. Loos in villa design will be expressed in the form of fuzzy rule bases. The formulation of rules will result from the analysis of individual villa designs and will be based on theoretical concepts pertaining to Loosis work -- in particular, on his designing process drawing on the concept of a Raumplan. Further, the concepts of the theory of architecture, related to a general procedure of construction design, will be utilized. The article also gives examples how to employ fuzzy sets in describing a building and its characteristics.
Del Signore, Marcella, Bradley Cantrell, and Barbara Roppo. "HYBRIDS: Urban Systems and Information." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 843-850. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Digital tools are transforming design pedagogy by continuously redefining approaches to design processes and methodologies. A recurring theme in design education is the link between the analytical processes and the project development. While the investigations are formulated during the first phase, one typically moves back and forth between the two, allowing ideas created from the analysis to influence and modify the overall design directions. The data created through digital tools can be manipulated, altered, modified and, because of its inherent properties, carried throughout the overall design process. The focus of  “Hybrids” seminar was to develop a strategy in which the analytical information and data created through digital tools, were able to inform a synergistic analog:digital design process. The seminar asked students to develop a temporary installation at the New Orleans Riverfront (Figure 1) focusing on the liminal condition that exists between the city and waters edge.  The site is a nodal point between the French Quarter and the river that presents different levels of information and acts as a threshold between the city and the water edge.
inici, Sebnem Ç.. "Immaterial-Material Reality, Computation and Architectural Design." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 105-112. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Computational design technologies are providing the conditions to advance the ways of design thinking and making. Though there are diverse approaches in the current architectural ideations and applications, the images produced by these technologies grab the most attention. These images mostly show off how different architecture can be by the use of computation. This paper will be criticizing this existing condition by discussing the change in the concept of “reality” with the advance of digital technologies, and its effects on our understanding of architectural materiality. So besides being a critique on current “picture” of architecture, this paper aims at dragging attention to the implicit potential of the current computational technologies in a different perspective.
Ediz, Özgür. "Improvising' Architecture: a Fractal Based Approach." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 593-598. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In this study, a computational, generative design model is investigated in the context of an approach based on improvising in architectural design.  This approach asks the question: “How can fractals be used in the architectural design process?i The initial focus is the similarity between the architectural design process and musical improvisation. This is informative because improvisation in the design process can aid in developing numerous design alternatives. An understanding of improvisation in jazz music is particularly relevant for the architectural design process.
Menges, Achim. "Integral Computational Design for Composite Spacer Fabric Structures: Integral Processes of Form Generation and Fabrication for Sandwich Structured Composites with 3D Warp-Knitted Textile Core." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 289-298. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Spacer fabrics are three dimensionally warp-knitted textiles that can be draped over complex double curved surfaces with no need for cut patterns or additional seams. This paper explains the development of an integral computational approach to the design and fabrication of sandwich composite structures with a spacer fabric core. Contrary to the common hierarchy of architectural design processes that prioritizes the definition of form over the inherent characteristics of materialization, this approach aims at an integral computational design process capable of unfolding a design from the constraints of making. The way the material capacity of spacer fabrics combined with the constraints of sandwich composite manufacturing directly informs the computational design process will be explained along the development of two prototype structures.
Ilal, Mustafa, Serdar Kale, and Altug Yavas. "Introducing Interdisciplinary Collaboration into Design Curriculum: Identifying the Appropriate Technological Infrastructure." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 129-136. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. There is an increasing adoption of BIM technology in the AEC industry. Organizations are forced to restructure their practices. The role of the architect within the new multi-disciplinary design team will depend on the architectsi skills in communicating with other team members. Architecture schools need to prepare students for this change. Collaborative aspect of design should be incorporated into the curriculum. This paper reports on the collaboration initiative between the architecture and civil engineering departments at Bal_kesir University. The initiative is investigating the extent to which courses can be coordinated across departments. Students from three different courses have been asked to provide analysis and feedback for the same project concurrently. The results confirm that BIM technology can effectively support collaboration even among undergraduate students who are relatively inexperienced with interdisciplinary data exchange.
Vamvakidis, Simos. "Légumes Urbaines: Digital Modeling Transformations + Prototype Fabrication Based on the Egg Crate Construction Method." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 313-322. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This study is divided in two areas. First, investigating the architectural, structural and possible program qualities of the egg crate. The fundamental exchange between the mathematical realm -in the form of digital modelling- and the material realm - in the form of material prototype fabrication and manufacturing- is the second goal. This paper also focuses on a basic design problem: how to produce a system of variable cavities and niches as opportunities for adjust to different programmatic needs as well as different terrain conditions based on the egg crate construction method. The egg crate was first used as a conventional aspect of masonry systems of construction, from wooden boats to building hulls. Simply put, itis a matrix of horizontal and vertical structural elements (or parallel to the x and y axis). The findings were incorporated into the design of prototypes for small-scale urban furniture / installations, the “Légumes urbaines”.
Varano, Sandro, Tristan Truchot, and Jean-Claude Bignon. "Ludic and Didactic Paths in a Cultural Heritage Building: Prototype of a Learning System." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 631-638. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This article proposes a conception method of ludic and didactic paths improving the acquisition of knowledge of archaeological and architectural heritage. In order to have an idea of a monument, the learner is guided and motivated following strategic paths during the 3D exploration and developing a memory map during the creation of knowledge. A prototype is realized and presented in order to see how this learning system guides the reasoning of the learner and can improve the acquisition of knowledge. We chose the Cheops Pyramid to Gizeh to illustrate our work.
Jensen, Mads, Henrik Mortensen, Michael Mullins, and Poul Kirkegaard. "Material Systems: a Design Approach." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 721-728. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper describes and reflects upon the results of an investigative project which explores the setting up of a material system - a parametric and generative assembly consisting of and taking into consideration material properties, manufacturing constraints and geometric behaviour. The project approaches the subject through the construction of a logic-driven system aiming to explore the possibilities of a material system that fulfills spatial, structural and performative requirements concurrently and how these are negotiated in situations where they might be conflicting.
Haeusler, Matthias. "Media-Augmented Surfaces: Embedding Media Technology into Architectural Surface to Allow a Constant Shift between Static Architectural Surface and Dynamic Digital Display ." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 483-490. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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 “fabrici to be used as a sort of media clothing for architecture in the electronic age (Ito, 2001).

Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This study is about building a conceptual architecture called Meta-form that can perform the acts of parametric design to generate various house forms. The study limits its scope to four genotypes of residential houses in the world. Typological Analysis is employed as a technique of distinguishing the key variables shared by the built forms. The result, with respect to each genotype, there are specific meta-form systems account for the generation of cases of phenotype by assigning different values to each corresponding parameter. With its generative power the meta-form system is evidently a useful tool to assist type-based form productions. As such, the parametric values also acquired the descriptive power of specifying built form characters.
Richens, Paul, and Georg Herdt. "Modelling the Ionic Capital." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 809-816. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In the course of a study into the origins of the Ionic order, a group of fragmentary early capitals of historic importance were measured by short-range laser-scanning, and then reconstructed in their original state by means of NURBS surface modelling. Drawings, renderings and scaled facsimiles were produced from both types of model, and proved invaluable in the formal analysis of the objects by architectural historians. It is suggested that these digital methods are more objective and accurate than traditional drawings and plaster reconstructions, and the resulting datasets more sustainable and of greater value to subsequent researchers.
Cannaerts, Corneel. "Models of / Models for Architecture: Physical and Digital Modelling in Early Design Stages." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 781-786. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper questions whether physical and digital models can be seen as models for rather than models of architecture.  Stressing the mediated nature of the design process, it  questions the role models play in the early stage of architectural design. This research draws from an experimental digital & physical modelling workshop. The conclusion argues for a modelling process that incorporates both physical and digital modelling, and acknowledges the mediated nature of the design process.
Loemker, Thorsten, and Katharina Richter. "On Computational Design and Critical Thinking in Architecture." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 113-118. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The paper examines the potential of existing traditional approaches in knowledge engineering against the background of current trends in the use of information technology in architectural design. The focus of this debate will be put on the commonalities of these approaches. The key concept they share is learning from the past, be it humans or be it machines. The vision they arise from is thereby as old as mankind. It is the wish to augment human thinking by artificial devices. The aim of the paper is to remove the scales from the eyes of those who neglect the past, be it in the architectural design process or in the use of Information Technology in architecture. The paper understands itself as a position paper and was moreover inspired by the announcement of the conference theme.

In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 47-52. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The paper exemplifies a collaborative design approach of architects and engineers by two projects that remotely resemble shell structures. Their geometry is rather driven by a complex network of manifold requirements. Parametric modelling and scripting is used to enhance collaboration and speed up the synthesis analysis loop.
Gil, Jorge, Nuno Montenegro, José Beirão, and José Duarte. "On the Discovery of Urban Typologies: Data Mining the Multi-dimensional Character of Neighbourhoods." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 269-278. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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.
Mueller, Volker. "Ontology for Computational Design: Computational Methods versus Cultural Processes." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 441-448. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In the ongoing taxonomy and ontology work in and about the computational design domain varying progress has been made. While in the ontology work oriented towards computational use within the domain a human-based approach appears favored, in the ontology work focused on the research domain the focus seems to be on computational approaches. This paper proposes to extend the human-based approach to the construction of an online research domain ontology in order to utilize inter-human collaboration to capture the fundamentally cultural phenomenon of language or vocabulary and its agreed upon meaning. Online availability would allow referencing for tagging of contents, for example for use in keyword lists, or for computational categorization of collections. Such an effort would add a research community forum for continued discourse about the research domain.

"Participative Technologies: an Internet-based Environment to Access a Plural Design Experience: Knowledge Modeling to Support User's Requirements Formalization." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 515-522. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. “Re-shaping artificially the Earth on human needs” implies a very complex industrial system that is performed through a very complex process. It consists of a collective, finalized and plural-constrained process, scheduled by phases, made up by several actors, characterized by the co-presence of numerous and very different (non-) specialist skills. In this paper we define the enhancement path of a web-based collaborative environment - discussed in a previous work - laying upon actual design entities representation an innovative logical level for knowledge formalization. It is presented an example of end-users requirement formalization, aimed at supporting the designers in the process by means of rule-based project suggestions.

Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. A computational approach for the automated graph representation and diagrammatic notation of all underlying symmetry structures of three-dimensional shapes with a center of symmetry is briefly presented and some applications with shape grammars to illustrate these ideas are discussed in the end.
Vaughan, Josephine, and Michael Ostwald. "Refining the Computational Method for the Evaluation of Visual Complexity in Architectural Images: Significant Lines in the Early Architecture of Le Corbusier." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 689-696. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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 architectsi works including those of Le Corbusier. However, while undertaking this research the computational method revealed unexpected results for the visual complexity of Le Corbusieris 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 Corbusieris house designs to examine the sensitivity of the method.

We propose and describe a working computer implementation for shape grammars that handles embedding relations in two dimensional shapes. The technical framework proposed explores a graph data structure to temporarily represent boundary elements of shapes and how they are assembled. With the associated algorithms, this structure enables a systematic search for parts. The employment of user defined constraints allows for an interactive search. In accordance with the continuous character of shapes, the study puts forth a practical part detection method, which extends to non-deterministic cases.
Yazar, Tugrul, and Oya Pakdil. "Role of Studio Exercises in Digital Design Education: Case Study of the Nine-Square Grid." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 145-152. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper is about short term and contextually limited kit-of-parts exercises in architectural education. Studio exercises are one of the key educational tools in architecture, which should be reconsidered with the developing technologies. As design computing becomes the mainstream thinking in architecture, the need for not only renewed studio exercises but for new educational frameworks becomes an essential issue. Thus, in this paper we will be proposing a different perspective on digital studio education, by explaining the fundamentals of studio exercises and their digital transformation potentials. Our experience with one of the most common kit-of-parts exercises, the nine-square grid, as a computational design problem for the first year students will be presented here as a part of this on going study.
de Godoi, Giovana, and Gabriela Celani. "Shape Grammars and Historical Town Renovations: a Case Study in Monte Alegre do Sul." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 237-242. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Shape grammars have been used in architecture for analysis and synthesis - in the first case, mainly for the characterization of styles and in the later for the generation of novel compositions. The present research proposes the use of shape grammars for establishing guidelines for the requalification of historical areas that have lost their original characteristics due to improper renovations. In order to develop and test the proposed method, a study was carried out in a small Brazilian town called Monte Alegre do Sul. The town was chosen because its original urban morphology, developed in the XIXth century, is still relatively well preserved, although part of the original façades have been transformed. The objective of the research is to develop a shape grammar to set guidelines for the requalification of the already renovated façades in Monte Alegre do Sul.
Thompson, Emine, and Margaret Horne. "Sharing 3D City Models: an Overview." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 261-268. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This study describes the computing methods now available to enable the sharing of three-dimensional (3D) data between various stakeholders for the purposes of city modelling and considers the need for a seamless approach for sharing, transmitting, and maintaining 3D city models. The study offers an overview of the technologies and the issues related to remote access, collaboration, and version control. It builds upon previous research on 3D city models where issues were raised on utilizing, updating and maintaining 3D city models and providing access to various stakeholders. This paper will also describe a case study which is currently analyzing the remote access requirements for a sustainable computer model of NewcastleGateshead in England. Options available will be examined and areas of future research will be discussed.
Burry, Jane, and Dominik Holzer. "Sharing Design Space: Remote Concurrent Shared Parametric Modeling." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 333-340. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper reports on research involving researchers and senior undergraduate students investigating the potential for sharing parametric digital design models via a central server using version control software for file sharing and locking. The innovation is introducing remote shared flexible modelling in very early design to observe firstly, the negotiation of protocols for working together in this environment and secondly the generative and constraining impacts of working in a flexible relational model with other unseen hands at work.
Whitehead, Hugh. "Social Experiments in Design Technology." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The delivery of a successful project demands high levels of collaboration across an expanded design team, which now includes consultants, fabricators and contractors as well as architects and engineers. The pace of development in design technology has been very rapid during the last few years and there are now many software products which offer high levels of sophistication. Most provide associative and parametric modelling strategies, which can be further enhanced and extended by the use of scripting languages. Designers are becoming tool-builders while fabricators are becoming digital craftsmen. With the advent of fast efficient drawing extraction the industry is at last making determined steps towards a model-driven process. However there is no integrated platform which supports the free exchange of ideas, combined with the evaluation of performance, experimentation with production techniques and the evolution of project-specific workflows. In education the design schools have been quick to recognise the potential of the new design technology. This has led to a rapid expansion in course curricula that now offer many new specialisations, most of which also need to be under-pinned by a good grounding in descriptive geometry, mathematics and physics. The architect as a generalist, who coordinates the work of specialists, is being challenged by an increasing breadth of technical studies that require more than just a superficial depth of understanding. In practice the gulf is widening even more rapidly. New graduates, who often have spectacular expertise in modelling and fluency in scripting languages, do not yet have the design and construction experience necessary to direct their efforts to best effect. On the other hand people running project teams do not have the technical background to understand the potential of the skills and resources that are available. Today there is no longer the continuity that used to derive from apprenticeship. As we experiment we find that tools based on new ideas and techniques can radically change workflow - but fear of the unknown can provoke resistance. So the problems we face in harnessing the new technology are as much social and cultural as they are technical. The presentation will focus on developing attitudes towards tool-building with the aim of integrating design, analysis and production. This is part of a continual and quite gradual process, which requires the ability to play interpretive roles that help to bring about cultural change. Examples will be shown from the work of the Specialist Modelling Group at Foster+Partners who now have tenyears experience in deploying design technology in an environment where research is intensely project driven.
Knight, Michael, and Wolfgang Dokonal. "State of Affairs - Digital Architectural Design in Europe: a Look into into Education and Practice - Snapshot and Outlook." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 191-196. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper updates a research project that tries to take a snapshot on the use of computers in the average architectural firms in two European countries. Our main interest is to see whether the digital design methods are starting to have an impact in these offices. First results of this research using an online web questionnaire have been presented at the eCAADe 2007 conference in Frankfurt and have been updated and presented at the Sigradi 2008 conference in Havana. At the moment we are working with additional interviews and we are preparing a rerun of the questionnaire to have an idea about the current developments. This paper is still based mainly on the findings we presented at the Sigradi conference to bring this information to the eCAADe community as well. We will be presenting the results of the new questionnaire in Istanbul.
Papapavlou, Aikaterini, and Alasdair Turner. "Structural Evolution: a Genetic Algorithm Method to Generate Structurally Optimal Delaunay Triangulated Space Frames for Dynamic Loads." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 173-180. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper presents an evolutionary algorithm that draws its power from the literal interpretation of the natural systemis reproductive process at a microscopic scale with the scope of generating optimal Delaunay triangulated space frames for dynamic loads. The algorithm repositions a firm number of nodes within a space envelope, by establishing Delaunay tetrahedra and, consequently, creating adaptable optimised space frame topologies. The arbitrarily generated tetrahedralised structure is compared against a canonical designed one and the results of this comparison indicate that the method proposed has advantageous properties and is capable of generating an optimum structure that exceeds statically the performance of an engineered tetrahedralised space frame.
Gül, Leman F.. "Studying the Impact of Immersion on Design Cognition." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 615-622. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. With the recent developments in information and communication technologies, designers have adapted digital tools and new ways of designing into their practice. In order to develop efficient systems for designing, the adaptation of new tools and techniques in design practice requires a better understanding of how designers employ the digital medium and what impact the digital medium have on designers cognition. The latter one is the subject of this paper. The paper presents the methodology and the initial results of a pilot to investigate the impact of immersion on design cognition. The initial result of the pilot study indicates that the designers were able to adapt to each design environment which affords different kinds of activities and requires different cognitive load.
Wurzer, Gabriel. "Systems: Constraining Functions through Processes (and Vice Versa)." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 659-664. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. We propose a novel computer-based design method for planning process-driven buildings. The method binds functions to processes, in order to avoid (1.) functions that are not present in any process and (2.) processes that lack some of their required functions.
Liapi, Katherine A., and Jinman Kim. "Tensegrity Structures of Helical Shape: a Parametric Approach." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 53-58. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Tensegrity grids composed of  tensegrity units that form double layer cable nets of single or double curvature can find applications in architecture as surface structures. In this paper a parametric process for the geometric configuration and representation of double layer tensegrity structures of helical shape is discussed. Departing from the geometric construction process, an algorithm that facilitates  the parametric description of helical tensegrity structures has been developed. The algorithm reflects the  interdependence of all parameters involved in the design of helical tensegrity structures and has been integrated into a software application that enables the automatic generation of virtual models of helical configurations in a graphic environment.
Henriques, Goncalo, José Duarte, and António Brito. "TetraScript: Development of an Integrated System Capable of Optimizing Light in a Circumscribed Space." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 31-38. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The purpose of this research is to develop a process capable of optimizing the capture of light in a circumscribed space, using a responsive system of skylights. Research is focused on the design of irregular dome-like pavilion spaces circumscribed by curved surfaces, but the envisioned process might be applied to other functional, formal, and spatial typologies. The design of the pavilion starts with the generation of a surface, later tessellated into a matrix of skylights depending on the geographic location and sun orientation. In the constructed pavilion, the skylights react to the variation of daylight intensity during the day to satisfy specified internal lighting needs. Simultaneously, the integration of conception and fabrication using digital tools (CAD-CAM) facilitates the construction of a non-standard, parametric geometry, thereby diminishing the costs of production and allowing for personalization, while assuring global sustainability.
Kontaxakis, Dimitris, and Spiros Papadimitriou. "The ''Formalization of the In-Formal: Design and Materialization Evolution of 'Paramana Square as a Case Study." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 399-406. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Informal has to do with shifting certainties and the insertion of unexpected, chance and improvisation. The “formalization” of the informal is the subject of this paper, seeking to explore the possibility to have atypical and not rigorous formalizations. But if that is possible until what point informality can be described and designed? By presenting an experimental and realized architectural project we bring forward the necessity of rethinking the concepts of design and construction evolution. There is a strong relation between techniques and the generation, control and construction of complex forms. It is clear that the animation techniques and the dynamic vectorial systems that they are used during the design process played a vital role in the liberation from a pre-conceived typology, as well as in morphing, in controlling, and in materialization of the new that didnit exist before.
Ilal, Mustafa. "The Building Performance Perspective for Interoperability: Requirements for a Future Analysis Network." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 89-94. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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.
Halatsch, Jan, Myrsini Mamoli, Athanassios Economou, and Gerhard Schmitt. "The Hellenistic City Model Inspired by Koolhaas: a Test Case for a Generic City Model." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 279-286. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In this paper, we suggest a generic city description model suited for purposes like semi-automatic city modelling 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.
Turan, Bülent, and Murat Soygeni_. "The Impact of the Digital Design Process on a Traditional Design Studio: Comparative Analysis on the Impact of the Digital Design Process on a Traditional Design Studio." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 773-780. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. To apprehend and apply the design concepts is directly related to the content of the education, the participation of the students in the design process and the design media facilities. The computer as a different design media affects the design process and also the design product. Accordingly, as a considerable fact, some of the courses in the architectural education program are based on the digital medium. However, enhancing the integration between the design courses, implemented in the studios, as a main part of the architectural design education and the digital media courses is contemplated as an actual requirement. In this context, regarding to the complement enclosure of this research, considering the affection of the transformations of the design pragmatics to the design educations, the traditional and the digital design methodologies are comparative underscored, and also the contributions of the digital design methodology to the traditional way of artificial manufacturing are analyzed during the development process of the design. For this purpose, the design theories, the digital design methodologies and accordingly the investigation properties about the construction of the theoretical conceptualization of the digital methodology, the approaches about the education and the design methodologies are literally overviewed. This comparative analysis had constituted the main comprehension of this inquisition.
Van der Maas, David, Mark Meagher, Christian Abegg, and Jeffrey Huang. "Thermochromic Information Surfaces: Interactive Visualization for Architectural Environments." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 491-496. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In this paper we describe a series of nine prototypes that were constructed to explore the benefits and limitations of thermochromic ink as a material for the design of architectural information surfaces. Among the goals of the project were the identification of inexpensive fabrication methods that could be used to build thermochromic surfaces at the scale of a room. Our primary design concerns were the ability to communicate information about indoor climate, and the integration of the information surfaces in an architectural environment. We propose a method for building thermochromic surfaces based on printed circuit boards (PCB) that is cost-effective, highly precise, and allows the fabrication of large surfaces through tiling.

In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 385-390. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper shares findings from the project DevA (Developable surfaces in Architecture), a research by design based project developed a collaboration between academic and industry partners. The project aims to investigate the use of curved sheet material in architecture using hybridised 3D modelling and pattern cutting techniques. The project investigates how digital design and fabrication technologies enable the development of new structural concepts through the new means of material specification and detailing at unprecedented levels of precision. The paper presents speculative research project as well as the demonstrator Reef Pattern.
Hemmerling, Marco. "Twister: an Integral Approach towards Digital Design and Construction." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 299-304. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The paper outlines the relevance of computational geometry within the design and production process of architecture. Based on the case study “Twister”,  the digital chain - from the initial form-finding to the final realization of spatial concepts - is discussed in relation to geometric principles. The association with the fascinating complexity, which can be found in nature and its underlying geometry was the starting point for the project presented in the paper. The translation of geometric principles into a three-dimensional digital design model was followed by a process of transformation and optimization of the initial shape, that integrated aesthetic, spatial and structural qualities as well as aspects of material properties and conditions of production.
Noriega, Farid, JohnD. Fynn, and Mary McDonald-Rissanen. "UNITALKS: a Blended Learning Platform for University Specific Foreign Language Training for Architecture Students." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 349-356. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The objective of the UNITALKS project is to develop a blended e-learning solution for foreign language training adapted to the university environment and to careers in architecture and building construction. Based on the VoiceForum project, an Internet or Intranet based platform, the approach aims to create an immersive task-based collaborative learning environment incorporating certain free software tools including a wiki repository where students and tutors can interactively and creatively enrich their learning community with new resources. UNITALKS is forward-looking in its recognition of the social as well as the technological dimension of an effective learning strategy and innovative in its approach to designing discipline-specific content tailored in a staged process to support maximum learner engagement and full operational ability in the professional context.
nder, Deniz Ö., and Yildirim Gigi. "Urban Spaces by the Space Syntax Method: a Proposal for the South Haliç Region." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 827-834. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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 cityis 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.
K_nayo_lu, Gökçe. "Using Audio-Augmented Reality to Assess the Role of Soundscape in Environmental Perception: an Experimental Case Study at UC Berkeley Campus." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 639-648. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Sounds, along with other senses, have a profound influence on our perception of the environment. The multi-modality of perceptual processing is influential in cognitive interpretation, semantic and aesthetic evaluations of environmental scenes. This paper describes an experimental case study using audio-augmented reality, carried out in order to better understand how sound influences sense of place. A correlation is established between soundscape and sense of place that depends on audio-visual congruence based on cultural, aesthetic and semantic factors. Subjective influences of soundscape on place experience are grouped and discussed under 5 areas that were possible to identify: Emotive and synaesthetic effects, effects on attention, gaze and behaviour, effects on spatial orientation and sense of scale, influence of audio-visual congruence on sense of place, and perception of personal and social space.
Elkær, Tim. "Using Computers to Aid Creativity in the Early Stages of Design - or Not!: Rehabilitating the 2D/3D physical representation in Computer-Aided-Ideation." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 761-768. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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 modelling 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.
Ehsani, Ehsan, and Scott C. Chase. "Using Virtual Worlds as Collaborative Environments for Innovation and Design: Lessons Learned and Observations from Case Studies in Architectural Projects." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 523-532. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In this paper we discuss observations and lessons learned in conducting architectural design projects in virtual worlds. By integrating a community of users in virtual worlds into a collaborative architectural design process, organisations can tap the communityis creativity and intelligence through immersive technology. The paper provides an overview of the latest advances of information and communication technologies in immersive virtual environments and discusses some of the observations and lessons learned which should be taken into account in developing collaboration models for such activities. Here we propose four modes of collaboration, based on the choices for degree of openness and governance structure, which are illustrated by four case studies.

In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 507-514. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. This paper describes how the Value Lab is a) developed  and b) used in education, research and workshops for (1) Interactive urban design and scenario planning that includes methods to support concurrent collaborative urban design over distances, and scenario planning based on defined case studies, (2) Visualization techniques for the detection and prediction of changes in urban environments, (3) Knowledge transfer to synthesize, interact with and communicate essential knowledge and findings from an array of disciplines for decision making, education, training, demonstration, and public discussions.
Gün, Onur. "Value through Precision, Beyond the Realms." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 377-384. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Today we portray designs with analytical systems and systems with the emerging terminology of computational design. Generative, intelligent, digital, parametric, associative, biomimetic designs sound valuable, whereas the integrity remains questionable. The tool, enabling designer to play with forms, patterns, models is neither granting him the knowledge nor teaching him the appropriate technique. Are we really able to digest and master all the information weire subject to, to be used in our designs? Or do we have much to learn about the investigations of the renaissance men to reach to a level of proficiency?
Zupancic, Tadeja Strojan, and Matevz Juvancic. "Virtual Space Design: a Flexible Learning Model: Respecting Fragile Places in Virtual and Physical Realities." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 137-144. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. The intensive programmes offer an opportunity to introduce fast changing and developing fields into the experience of architectural students regardless of the flexibility level of curricular structures and institutional contexts. The main aim is to enhance and promote place-sensitive interventions in physical and virtual worlds. The paper concludes with a discussion of intentions, experience gained, some sobering moments as well as the learning curves of participants and organizers when it comes to design culmination of sensitive physical and virtual realities.
Achten, Henri, and J. Beetz. "What Happened to Collaborative Design?" In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 357-366. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. In this paper we present the results of a comprehensive literature survey on the development of collaborative design. We reviewed 324 papers on collaborative design, taken from various sources (conferences, journals, and PhD-theses). We grouped the papers based on common themes, and in that way derived a classification of themes through the last 25 years (1983-2008). Each category is described, its development, and key publications are identified.
Stiny, George. "When is Generative Design Design?" In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. 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 isn't design. EMBEDDING is needed, as well. This entails a switch from blindly following rules to seeing what happens. Then calculating in Turing's way by counting is a special case of calculating in an artist's or designer's way by seeing. And creativity as recursion – in logic, linguistics, and computer science – extends to art and design. Generative design is design if there's embedding, that is to say, anytime there's 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.
Barlieb, Christophe, Christoph Richter, Björn Greschner, and Martin Tamke. "Whispering Wind: Digital Practice and the Sustainable Agenda." In Computation: The New Realm of Architectural Design: 27th eCAADe Conference Proceedings, 543-550. eCAADe: Conferences. Istanbul, Turkey: Istanbul Technical University, Faculty of Architecture, 2009. Low frequency noise generated by aircraft during pre-takeoff, takeoff, landing and post-landing operations equates to high levels of undesirable ground noise pollution. This phenomenon is gaining heightened popular interest among air transportation specialists and agencies as urban settlements and airports expand beyond post-war city limits to meet demands of the 21st Century. This paper highlights the advantages of employing digital tools in tight collaboration with academics and professionals at the early stages of the design process and revisits ancient architectural design strategies to arrive at more meaningful and sustainable architectural interventions.
