title	Diagraphics: an exposé of visual expression
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 400-404
summary	This exposé introduces preparations for a publication based on what I have found to be a ‘missing link’ in the library of educational source materials. The skills necessary to record and interpret the complexity of the architectural design process are often illusive. The sophistication of computer modeling and graphics applications only adds to the dilemma of making clear and concise decisions about how to communicate the essence of one’s design intent. The publication will define and illustrate five Diagraphic models of analysis. Each offers ways of seeing and understanding the idiosyncrasies of recording the design process. Gestures, Traces, Pulls, Morphs and Transits exemplify specific modes of visual expression and integrate both their diagrammatic and graphic nature. The distinctive aspects of each model enable the student of architecture to choose appropriate and meaningful techniques for visual expression. The publication will also illustrate current and historically relevant examples of diagrammatic expression. These examples show how diagrams have been flexible over time in adapting to the needs of newly forming conceptual models, spatial analysis and belief systems.

title	Responsiveness and Social Expression; Seeking Human Embodiment in Intelligent Façades
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 12-23
doi	https://doi.org/10.52842/conf.acadia.2005.012
summary	This paper is based on a comparative analysis of some twenty-six intelligent building facades and sixteen large media-facades from a socio-psychological perspective. It is not difficult to observe how deployment of computational technologies have engendered new possibilities for architectural production to which surface-centeredness lies at that heart of spatial production during design, fabrication and envelope automation processes. While surfaces play a critical role in contemporary social production (information display, communication and interaction), it is important to understand how the relationships between augmented building surfaces and its subjects unfold. We target double-skin automated facades as a distinct field within building-services and automation industry, and discuss how the developments within this area are over-occupied with seamless climate control and energy efficiency themes, resulting into socially inert mechanical membranes. Our thesis is that at the core of the development of automated façade lies the industrial automation attitude that renders the eventual product socially less engaging and machinic. We illustrate examples of interactive media-façades to demonstrate how architects and interaction designers have used similar technology to turn building surfaces into socially engaging architectural elements. We seek opportunities to extend performative aspects of otherwise function driven double-skin façades for public expression, informal social engagement and context embodiment. Towards the end of the paper, we propose a conceptual model as a possible method to address the emergent issues. Through this paper we intend to bring forth emergent concerns to designing building membrane where technology and performance are addressed through a broader cultural position, establishing a continual dialogue between the surface, function and its larger human context.

title	Analysis of the possibilities offered by the application of parametric modeling technologies in the design processes shared between architects and industrial designers: The prefabricated house case.
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 300-303
summary	Traditionally, the teaching of digital design systems has been focused on the operative learning of software. However, this almost exclusively technical approach has leaded to a partial view of these systems, as well suited platforms to exploration of project’s possibilities. Consequently their relevance as a base for project representation and therefore as a useful instrument for conceptual exploration for design and experimental research of their processes have been undervalued. On the other hand, this restrictive perspective results in an important waste of the teaching possibilities lying in CAD software related with interdisciplinary teamwork. The following academic experience obeys to a new insight of how to teach these tools, based upon problem solving in Design by interdisciplinary students work teams from Architecture and Industrial Design. In this bet, the learning process is flexible, shared and collaborative, according to the requirements of each project, powered by the commitment of facing common goals. [Full paper in Spanish]

title	Conceptual Content of Digital Design

summary	Concepts related to digital architecture have begun to occupy a central role in current architectural discourse. Design concepts that have been the conceptual content of this discourse are now becoming integrated into the general architectural discourse. The research reports on this process of the emergence, migration, and crystallization of a new conceptual structure over the past decade under the influence of digital design and its emerging conceptual structure. The research presented in this paper examines the emergence of new ideas in architectural thinking that are related to digital architecture since 1990 until today. In order to demonstrate this shift, we have selected a representative architectural building type that is strongly and directly influenced by the conceptual content of the cultural discourse in architecture. A museum type was selected to represent features of the expression that reflects the changes and evolution of conceptual structures that underlie digital design. The research methodology is based on a method known as “content analysis”. Content analysis in our research was de- fined as including textual material in books, book chapters, essays, articles, and historical documents. A new approach for Design Content Analysis was accomplished employing the ICF analytical framework. In order to conduct a content analysis the text was coded and was broken down into categories on a variety of theoretical design themes. Our findings demonstrate that certain expressions related to digital technology have moved up from a low level descriptive function to a significant conceptual role in formulating the design content of architectural design. In our paper we describe the research, methodology findings and contribution to the definition of the conceptual content of contemporary architectural discourse on digital architecture.

title	Digital architecture – Towards a new Discourse
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 473-477
summary	Discourse in digital architecture has begun to occupy new design concepts related to digital design. Design concepts are now becoming integrated into the general architectural discourse. This research investigated this process, the emergence, migration, and crystallization of a new conceptual content under the influence of digital design. In order to demonstrate this shift, significant projects were selected to represent features of the expression that reflects the changes and evolution of conceptual content that underlie digital design. This analysis was accomplished employing the ICF analytical framework. Our findings demonstrate the change in the conceptual structure in digital architecture. Certain expressions that are related to digital technology have moved up from a low level descriptive level to a significant conceptual role in formulating current ideational content. The methodology findings and the contribution to the definition of the conceptual content of contemporary discourse in digital architecture are described and presented in this paper.

title	Multi-user virtual worlds: 3D interactive visualization in synthetic environments for design workshops
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 344-349
summary	The goal of this research is to describe a methodology of architectural design by using digital technology with three-dimensional interactive simulation in multi-user virtual worlds. In addition, this study will focus on the application of this method in the workshops at the School of Architecture in the University of Zulia. With this proposal, it is possible to integrate many users, in real time, from different locations on the same virtual world in Internet. In the same way, each visitor is able to interact and modify the virtual world using virtual menus while sharing ideas or modifications regarding the design of the project. This strategy allows modeling, visualizing, developing and evaluating the designed projects during the conceptual and parametric phase in the process of design. This application is a powerful tool to develop creativity and skills of spatial perception among the students. [Full paper in Spanish]

title	From Bézier to NURBS: Integrating Material and Digital Techniques through a Plywood Shell
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 156-169
doi	https://doi.org/10.52842/conf.acadia.2005.156
summary	The development of digital fabrication has reintroduced material processes with digital processes. There has been much discussion about the tool and the objects of the tool, but little discussion of the implication of the material process on the digital process. A brief historical review on the development of computer numerical control and the origins of the Bézier curve reveals an instrumental fact: computer numerical controlled tools necessitated advancements in computational surfaces which eventually led to NURBS (Non-Uniform Rational B-Splines) surfaces. In other words, the origins of NURBS surfaces resides in its relation to material processes, rather than many current approaches that develop free form surfaces and then force the tool onto the material without regard to the material properties. From this historical and mathematical review, this project develops toward more intelligent construction methods based on the integration of NURBS differential geometry paired with material qualities and processes. Specifically, a digital technique of developing conceptual NURBS geometry into piecewise surface patches are then flattened based on the material thickness and density. From these flattened patches, a material technique is developed to intelligently remove material to allow the rigid flat material to re-develop into physical surface patches. The goal of this research is to develop digital and material techniques toward intelligent construction based on the correspondence between digitally driven surface and digitally driven material processes. The application of this technique as a rational and flexible system is to support the dynamic response of form and material toward such performative aspects as structure, daylight, ventilation, and thermal properties.

title	Three-Dimensional Shape Generation of Low-Energy Architectural Solutions using Pareto Genetic Algorithms
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 647-654
doi	https://doi.org/10.52842/conf.ecaade.2005.647
summary	This paper extends on a previous work on the application of a Generative Design System [GDS] to the evolution, in a computational environment, of three-dimensional architectural solutions that are energy-efficient and adapted to the climatic environment where they are located. The GDS combines a well-known building energy simulation software [DOE2.1E] with search procedures based on Genetic Algorithms and on Pareto optimization techniques, successfully allowing to tackle complex multi-objective problems. In the experiments described, architectural solutions based on a simplified layout were generated in response to two often-conflicting requirements: improving the use of daylighting in the space, while controlling the amount of energy loss through the building fabric. The choice of a cold climate like Chicago provided an adequate framework for studying the role of these opposing forces in architectural form generation. Analysis of results shows that building characteristics that originate successful solutions extend further than the building envelope. Issues of massing, aspect ratio, surface-to-volume ratio, orientation, and others, emerge from the analysis of solutions generated by the GDS, playing a significant role in dictating whether a given architectural form will prove adapted to its climatic and energy requirements. Results suggest that the questions raised by the exploration of form generation driven by environmental concerns are complex, deserving the pursuit of further experiments, in order to better understand the interaction of variables that the evolutionary process congregates.

title	Architecture and Biological Analogies
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 599-606
doi	https://doi.org/10.52842/conf.ecaade.2005.599
summary	The study described in this paper evolves within the larger context of a research aimed at inquiring into analogies between architecture and nature, and more specifically between architecture and biology. Biology is a recursive source of architectural inspiration due to the tight relationship between form and function, the natural balance of forces and the corresponding geometric solutions found in living beings. Roughly, one can classify historical analogies between architecture and biology into two main categories. The first tries to mimic biological forms and the second biological processes. The specific goal of the described study is to find how new technologies can redefine and support the process of constructing such analogies. It uses as a case study a tower project designed by the architect Manuel Gausa (ACTAR, Barcelona) called Tornado Tower because of its complex shape inspired in the frozen form of a tornado. Due to the geometric irregularities of the tower, Gausa’s team had difficulties in designing it, especially because solving the structural problems required constant redrawing. This paper describes the first part of the study which primary goal was to conceive a parametric program that encoded the overall shape of the Tornado Tower. The idea was to use the program to simplify the drawing process. This required a mathematical study of spirals and helices which are at the conceptual basis of the external structure and shape of the tower. However, the program encodes not only the shape of Gausa’s tower, but also the shapes of other buildings with conceptual similarities. Such class of shapes is very recurrent in nature with different scales and with different utilities. Therefore, one can argue that the program makes a mathematical connection between a given natural class of shapes and architecture. The second part of the study will be devoted to extending the program with a genetic algorithm with the goal of guiding the generation of solutions taking into account their structural fitness. This way, the analogy with genetic procedures will be emphasized by the study of the evolution of forms and its limits of feasibility. In summary, the bionic shape analogy is made by the generation of mimetic natural forms and a genetic process analogy starts with the parametric treatment of shape based on code manipulations. At the end the program will establish an analogy between architecture and biology both terms of form and process.

summary	The central feature of the project is the development of a computer and its interfaces to simulate urban space and, in the context of an intermedia city tour, to allow citizens to creatively influence their urban space by manipulating media structures at chosen points throughout the city. A master plan is set up to re-cultivate public spaces and points of architectural focus. The city reacts interactively to the commands. A dialog is created between user and public space. The tour route is an open structure which can be expanded at any time. Via interfaces the user activates a reaction in the real city by making changes to the virtual model. This results in a dynamic space, a communication based on the results of this transformation. The user interface allows an information transfer between real people and virtual space. Virtual reality then reacts to the input by transferring that information back to reality. The direct influence on the architecture is effected by a media-transformer. It projects an additional perception level on to reality while monitoring the data via various analysis interfaces.

doi	https://doi.org/10.52842/conf.ecaade.2005.467
summary	This paper presents research in computer modeling that ARIAM team of the school of architecture of Paris La Villette has been developing for several years. One of the aims of this research group is to develop computer systems that assist architects in modeling existing buildings or monuments from heterogeneous documents or data as drawings plans, sections, photos, measures taken on site etc. In spite of advances in computer recognition it’s a long way to have a system that could automatically recognize, from any bitmap document or photo, relevant architectural objects and automatically build the model these documents represent. However, if we could define a knowledge base about a particular domain, it would be possible to develop a system that could interpret specific documents that represent some kind of building or monuments. But, even in such limited domain, it is difficult to build an exhaustive knowledge base and user-interactions are generally required. We argue that a user could mark relevant information on the documents and thus facilitate the process of interpreting. The system we propose has three components: a graphical user interaction tool, an analyzer of documents and user interactions, and a generative tool that produces the required model. As an illustration, the paper presents a system we have developed which assists an architect in modeling a 3D mesh of gothic vaults for a finite elements analysis.

title	Poiesis and Autopoiesis in Architecture

doi	https://doi.org/10.52842/conf.acadia.2005.048
summary	The use of digital technology in architecture has proven to be more assertive than originally thought: it has reconditioned the nature of the design process, and established new processes and techniques of fabrication. Recent applications in digital technology show inquisitiveness in the contentious subject Genetic Algorithms. This new architectural process is characterized by two main shifts: from poiesis (or poetry) to autopoiesis, and from authenticity to mimesis. Since evolutionary simulations give rise to new forms rather than design them, architects should now be both artists and operators of both Inventive and Systematic design. Inventive design: The digital media should bring about poiesis (poetry). Digital spaces reveal and visualize the unconscious desires of urban spaces, bringing forth new dreamscapes, mysterious and surreal. This implies a Freudian spatial unconscious, which can be subjected to analysis and interpretation. The tools of digital dreaming, meanwhile, have opened a window to the ‘urban unconscious’. Systematic Design: Digital media should bring about an autopoiesis. This approach calls into question traditional methods of architectural design that replace the hierarchical processes of production known as “cause and effect,” and propose a design process where the architect becomes a constructor of formal systems. Will the evolutionary simulation replace design? Is metric space dead? The new algorithmic evolutionary conditions give architecture an autopoiesis, similar to biological dynamics. Paradoxically, the new emerging process is more insightful. The emphasis of the exploration is on morphological complexity. Architecture, through “machine” fabrication, may become more responsive, rigorous and poetic.

doi	https://doi.org/10.52842/conf.ecaade.2005.671
summary	This paper describes how constraint modeling can support design innovation. Furthermore, it lays out how constraints are employed in the construction and exploration of a model’s design space. The paper places this approach within the larger context of design exploration using computational and conceptual representations of design. Four general constraint types are identified and examples from several workshops and design studios are presented for each of the constraint types. The examples range from product design to structural design to fabrication issues in architecture. Based on a review of the literature the most common constraints are of geometric, topologic, functional, and quantitative type. Based on the case studies the paper describes how the different types of constraints can be used as design drivers and help in the exploration of solution space. In conclusion the paper identifies the addition of bi-directional properties to constraint modeling as the next challenge in improving the application of constraint modeling in design exploration. Furthermore, the paper demonstrates the necessity to develop better constraint models for cross domain design.

title	Interdisciplinary Knowledge Modelling for Free-Form Design – An Educational Experiment
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 465-474
summary	The recent advances in digital design media and digital fabrication processes have introduced formal and procedural effects on the conception and production of architecture. In order to bridge the individual concepts and processes of multiple design disciplines, intensive cross-disciplinary communication and information exchange starting from the very early stages of design is necessary. A web-based database for design learning and design teaching named BLIP is introduced. In this framework, cross-disciplinary domain knowledge becomes explicit to be taught and transferred in Free-Form Design research and education. BLIP proposes a conceptual map through which the user can construct structured representations of concepts and their relationships. These concepts are high-level abstractions of formal, structural and production related concepts in Free-Form design development. BLIP is used for formalizing, organizing and representing conceptual maps of the three domains and facilitates information and knowledge sharing in collaborative conceptual design in context. The paper introduces the application together with its application in two educational design experiments.

title	A Biased History of CAAD

summary	The democratization and popularization of the computer has brought on fundamental changes to many areas related to computer science, including CAAD. Such areas have been facing the necessity to reposition and reorient themselves in rapidly evolving academic and professional frameworks. A factor that complicates the processes of repositioning and reorientation is that most areas have a short but varied and frequently incoherent history that may be poorly understood. The paper is an attempt to trace the history of CAAD by means of publications. This refers to both key publications and the thematic structure of the overall CAAD production. The underlying hypothesis is that CAAD derives from two distinct ambitions, the technology-driven, bottom-up development of architectural computer graphics and the more domain theory-minded, top-down automation of designing. A third, less popular ambition is the computerization of analysis and evaluation, which can be treated as a subcategory of the previous two. The results of the bibliographic analysis are summarized in a timeline that indicates a convergence of ambitions and approaches in the 1980s, the period when CAAD became a recognizable area. In the 1990s the democratization and popularization of the computer caused diversification of CAAD activities over a wide spectrum, ranging from support to end-use of computer systems to computational theory and including the development of advanced, specific applications in cooperation with other architecture, building or design specializations.

title	DEFINITION OF A METHOD OF LIMITS OF THE SIMPLIFICATION OF A HALL MODEL IN A CAD SYSTEM TO DIMINISH FALSIFICATION OF ACOUSTIC SIMULATION RESULTS
source	International Congress eCAADe 2005 (Education and research in Computer Aided Architectural Design in Europe), subject : “Digital Desing : the quest for new paradigms”, ISBN 0-9541183-2-4, pp. 695-704, Technical University of Lisbon, Portugal, 21-24 September 2005
summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi-EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.
