title	Tagging Your Body Virtually : Represent a place making process with social network
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 543-558
summary	This research focuses on the virtual environment of place making. In this paper we would like to emphasize that the place making should be stressed collective views in order to obtain the design application of possibilities. However, in past researches there has been no study that tried to collect the collective views by digital ways. Accordingly, this paper proposes a response thought the Spatial Intention. It could be used to represent the human of body experience. The "moving" and "standing" are appropriate to two main considerations. Both of these could be connected to the action of "focus" and "choice." these leads to a sequential relationship of place production. The positive significance of the spatial intention lies in the convertibility of physical experience could be implied with a specific understanding. It also could be used to mold the place of knowledge structure. Thereby in order to verify the reliability of the above, we made a social network of virtual environment and used the rapid prototyping method to develop a prototype system. Implementing on the Chinese garden of the actual case, we found that the tag could concentrate as an entire sense in somewhere of place. These tags also could be shared remotely through the social network. Different tags in the sharing mechanism could collage out a place of collective views. This perspective would be used to assist designers to understand the sense of place. It also would be applied to find out the environmental design of possibilities in the future studies.

summary	The objective of the paper is to demonstrate the application of architectural research and design methods from the fields of strategic design, digital production and design chains to facilitate the completion of demanding large-scale building projects. Since we have concentrated the efforts of the past few years on various aspects of building practice while applying and testing the “Digital Chain” method to several concrete projects, we are now engaged with linking the individual phases in order to make the final step towards the reality of building practice. With this knowledge, we attempt to propose a new way of thinking in the design and building sector based on digitized planning processes.

summary	The paper is focused on selected issues of preliminary education of computer techniques as part of first semester curriculum at a school of architecture. Teaching methods based on previously known research are tested and explored in a situation of clearly defined constraints: lack of architecture-specific knowledge of the novices and varying levels of their computer skills. The paper is based on three-year experience. Although we are all in the mood of saying: we do not teach software any more, we still have to think how to encourage students to develop their skills in computer techniques to the level that can liberate them from tool-dependence. The aim is to direct them towards task rather than tool oriented actions. Learning while designing causes the design process to be less important than representation. On the other hand, classic software courses are a thing of the far past and are not suited for design-oriented curriculum. There is a need to find alternative ways more suitable for a preliminary architecture IT course.

summary	Tomorrow’s architectural practitioners seemingly need to gain an overview of, if not master, a wide range of computer aided architectural design applications, from image making to Building Information Modelling (BIM) to digital fabrication. However, we are sceptical whether there is wide recognition that there is value in a broader appreciation of the underlying principles that organize these applications. CAAD software, once an exploration of architectural ideas, has become a commodity. But as digital tools have become more ubiquitous the relationship between practice and research has, broadly speaking, become more ambivalent. What has been lost, and what gained, in this change?

title	Trends in Graduate Research on IT & Architecture: a Qualitative Comparison of Tendencies in Brazil and abroad
doi	https://doi.org/10.52842/conf.ecaade.2007.431
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 431-437
summary	Applications of information technology (IT) in the architectural profession have greatly increased in the past decades, ranging nowadays from concept design to automated construction. There are countless applications in the architecture practice that go well beyond representation, such as BIM software, generative design systems, and rapid prototyping and fabrication. For this reason, IT has been a frequent graduate research topic. In the present research academic graduate theses that dealt with IT in architecture since 1999 were surveyed and categorized, with the purpose of comparing the topics, applications and methods that are studied in Brazil and abroad. We hope that the differences found will help Brazilian architecture schools to update their IT curriculum, overcoming old prejudices against the use of computers in the creative phases of design.

title	Seamless Architecture
doi	https://doi.org/10.52842/conf.ecaade.2007.805
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 805-811
summary	This paper considers the influence of digital fabrication (CAM) technologies with regards to the creative and creating processes and within the specific parameters of materials. Under the title seamless architecture this paper is seeking to study relationships (on a literal and conceptual level) with the existence or not in architecture of ‘seams’. This study draws inspiration from past and present architecture and also design fields such as textile and sailmaking, by examining types of ‘seamless envelopes’ which were only possible when advances in digital fabrication were met. Metal is currently widely used as cladding material. In antithesis to previous notions of steel being the ‘bones’ of architecture, expressing ‘strength’ and ‘sturdiness’, current use of metal as ‘skin’ material has revealed the ‘softer’, highly sculptural, almost textile quality of metal surfaces. Digital fabrication of sheet metals has contributed towards this shift. However, architectural metal skins presently lack this seamless quality of a ‘differentiated-single’ object. It’s capabilities as cladding material have not been fully utilized, in light of drastic developments in digital manufacturing. Design integration of aesthetic, structural and environmental considerations into the design of metal cladding systems is bound to develop in the future. Considering metals as textiles (in terms of architectural concept and manufacturing) can provide new insights to their utilization in architecture.

title	Closing the Gap: The e4d Design Series and the Mediation of Digital Design Skills
doi	https://doi.org/10.52842/conf.acadia.2007.204
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 204-211
summary	The e4d design series is looking for an innovative use of digital technology in architectural education to overcome the gap between design development and the acquisition of digital skills. Digital design approaches include multimedia technology, the crossover of analogue and digital techniques, rapid-prototyping, visualization, and the presentation in artistic movies. Over the past two years a problem- based design approach was developed, which enabled students to learn digital and architectural skills simultaneously and efficiently. The educational concept consisted generally of four steps, which, though independent of each other, are determined by questions of the ongoing design process. The first step consists of an abstract or subjective research phase; in the second step the findings are transferred into dynamic spatial structures. Later, the detected qualities are used to develop a given building program. Finally, the different traces are connected, when site-specific parameters are blended with the design traces. This paper examines and evaluates textual and visual design approaches, the precise use of different kinds of media for the projects’ visualization, and the way architectural projects can be discussed; in addition, a competent monitoring of the process and outcome of innovative and efficient design strategies in architectural and pedagogical aspect is included.

title	The Role of GIS in Documenting Bahrain’s Historic Cities
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 517-526
summary	Geographic information systems have long been established as useful tools for urban planning. The aim of this study is to put forward applications of GIS (Geographic Information Systems) to urban conservation in cities with architectural heritage. The study presents a specific database design to be integrated within a GIS, and the methodology of gathering data for such a database. This study concerns Bahrain’s architectural heritage, which includes many significant historic buildings as well as an overall traditional character of Bahrain’s old towns. This heritage is endangered due to extensive new urban development and the general neglect over the past decades. The study also describes an experimental database that is implemented for documenting the urban character of the old towns of Manama and Muharraq. This database was tested during a partial visual survey of Manama. It is hoped that this database will be the nucleus of a long-term process of urban conservation in the Kingdom of Bahrain. The work described here is part of a larger study conducted by the UNDP (United Nations Development Program) and the municipal government in Bahrain. A group of international experts in urban planning, urban design, and historic preservation also presented their own specific recommendations. The author of this paper was responsible for designing the GIS that helps in documenting the historic cities of Bahrain. This report proposes the development of a geographic information system for urban conservation planning. The system supports planning specialists and decision makers in their areas of work, such as the creation of urban conservation zones and redevelopment strategies. The system documents existing structures and their present conditions in order to assist in decisions regarding their preservation, restoration, and possible reuse. Such a system will also help the municipalities in regular heritage management tasks.

title	4D Building Model - A Conceptual System of the Time Dimension in the Building’s Life
source	Vienna University of Technology; Building Science & Technology
summary	The research topic ”4D Building model: a conceptual system of the dimension of time in building’s life” is the concept of a web-based interface of a databank that stores and visualizes information of the building’s life process. It is an organization data model that brings together the serial steps of the lifetime of a building, following the design, construction and its operation time. Observing the aforementioned process as an entity, the model aims at approaching the passage of time during it, depicting the temporal relations between past, present and future steps. Visualized stored information depict the becoming of the building in time. It attempts to approach the idea of 4D architecture and explore how the dimension of time is incorporated into the model. It studies the role of information in architecture and building process observing it changing in time. The aim of this research project is to define the frame of a conceptual information system, that could develop in a plug-in by an existing design software. The model will support the design and building procedure operating as the building memory, and reporting its behaviour during its life time. In its data base, there will be reported the serial and parallel actions during the design and construction phase and additionally the reports of the monitoring evaluating system during its operational time. The final model should provide several possibilities of decision making, regarding the energy consumption, the materials life span, the costs, the participation of different firms and components.

title	Fatal Fire Risk Checking for Residential Building Design
doi	https://doi.org/10.52842/conf.caadria.2015.303
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 303-312
summary	Building fire puts great threat on people’s lives and causes huge numbers of fatalities each year. In 2007, total fire death in the United States alone was 3,430. The number of fatalities is distributed among residential 75.5%, non-residential 3.6%, vehicle 16.7%, outside 1.6%, and other 2.6%. Although much research has been done on building fire simulation to support designing safer buildings, all simulation systems currently available are focused on major factors in non-residential buildings such as bottlenecks, arching, pushing, etc. Residential building fires and non-residential fires are very different in many aspects. Therefore simulation systems focused on non-residential buildings have little effects on residential buildings. In this research, we analysed major factors causing deaths in residential building fires, and filtered out building design related factors. We then developed a system which shows the risk of fatal fire in residential building designs. This system is expected to help architects to easily detect potential risks of fatal fire and design safer residential buildings.

title	Architectural Use of Computer Controlled Deformation Techniques on the Example of CNC-Bent Tube Structures
doi	https://doi.org/10.52842/conf.ecaade.2007.021
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 21-26
summary	Steel tubes as construction material have an enormous capacity. CNC bending machines have the ability to deform material into all three dimensions in contrast to other popular CNC techniques for architectural design that use subtractive methods like laser-cutting and milling. The research examines the potential of a digital deforming process of CNC-Bending. During three months the authors developed several design concepts, programmed the necessary software for generating the structure and produced three architectural prototypes shown at an exhibition. Altogether they were constructed out of more than 500 pieces of steel tubes and over 5000 bends.

title	Enablement or Restriction? On supporting others in making (sense of things)
source	Computer Aided Architectural Design Futures / 978-1-4020-6527-9 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Futures / 978-1-4020-6527-9] Sydney (Australia) 11–13 July 2007, pp. 585-598
summary	In this paper I present and reflect upon a five-year investigation of designing digital tools for designing in the area of architectural space grid structures. I understand design as a novelty and knowledge generating conversational process as described by Pask (see Scott 2001) and Glanville (2000). Furthermore, I regard making design tools as a design task in itself, rendering this paper a reflection on designing for designing. This paper gives a report on observations I made during the toolmaking study, and subsequently contextualizes these observations using second-order cybernetic theory. This reflection focuses on different relationships between observers and systems, on conditions under which observers construct knowledge and on limits of supporting others in this activity.

title	Analysis of Design Support for Kinetic Structures
source	Vienna University of Technology; Building Science & Technology
summary	This thesis attempts the formation and systemization of a basis of knowledge and information, which is indispensable to turn a design support for kinetic structures into representation by means of a 3d animating program. Representation of kinetic structures by means of the existing ordinary software sources is possible; Nevertheless, such representation lacks of different important features and functions and results eventually in the total absence of a real model of the construction, which is valuable to the user of the program especially in the field of the kinetics, where everything depends on the movement: design not only requires, but demands for visualisation. A personal interest in kinetic architecture and therefore in the physical movement of structural elements in a building, as well as an attempt to “fathom” the possibility of changing this concept to visualization and modern reality by the use of a software are the main incentives of this master thesis. First, a general research will be performed in order to check the existence of similar or semisimilar proposals. The area in which the research will be held is the Bibliography in kinetic architecture and parametric design. A comparison of animation and 3D prototype software in well-known programs will focus on whether virtual weather conditions are considered as a parameter to the animation of the structure of the programs and case studies of several existing kinetic structures will be performed, in order to point out flaws and/or helpful commands in the programs in connection with the presentation of kinetic architecture. Criteria for the choice of the software: ability to customise and to produce geometric modelling, animation in relation to time (video animation) and the simulation after taking into consideration weather factors. Finally, using the computer and the scripting language, based probably on the theory of parametric design and primitive instancing, a realistic simulation of different elements will be performed in relation to variable measurements of luminance, ventilation and temperature so as to render feasible the construction of a whole structure. The results of the thesis will be used in the future as the basic knowledge in the creation of software for simulation of kinetic architecture. This program will be used as a tool for the architect to present a building, where kinetic architecture will be applied and to create simulation of the kinetic movement through a library of the existing prefabricated elements which will be created with the help of this thesis.

title	An Integrative Design and Spatial Visualization System for Cable Strut Self-tensioned Structures
doi	https://doi.org/10.52842/conf.ecaade.2007.027
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 27-34
summary	Novel conceptions of structures consisting of spatial formations of struts and cables present a uniquely defined morphology and structural performance, and offer opportunities for innovative applications in building design. A common feature of these structures is that their spatial geometry is not “a priori” given. This paper is focused on a specific type of cable-strut structure that occurs from the assembly of self tensioned cable-strut modules The spatial configuration of these structures is very complex and necessitated the development of elaborate geometric algorithms that permit the generation of their formal geometry in a virtual 3D environment. To facilitate both the design and the construction of such structures, a spatial visualization system, which integrates a) algorithms for initial form generation, b) geometric parameters that simulate construction stiffening processes, and c) appropriate structural analysis methods, has been developed. The structural organization and parts of this system are presented in this paper. The system renders feasible the exploration of alternate geometries with various levels of pre-stress and displays initial and final configuration of the structure. It also allows for structural analysis data visualization. Examples of projects designed with the assistance of this system are included and discussed.

title	Simulating Dynamic Forces in Design with Special Effects Tools
doi	https://doi.org/10.52842/conf.ecaade.2007.219
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 219-226
summary	Special effects technology can facilitate dynamic sketching in the early stage of a design project without needing time-consuming effort. This form of sketching was tested in a design studio taught by the author. The study of dynamic materials and oceanfront site conditions set the stage at the beginning of a design process for a more comprehensive analysis later on. On the one hand, the risk of using special effects tools is that the visual look can seem convincing, but the apparent result is based upon an overly simplified set of assumptions. On the other hand, the use of such technology can be very stimulating to the design imagination without requiring complex analysis that may bog down the free flow of ideas. Once a greater commitment is made to a particular design proposal, more complete physical analysis and modeling can be undertaken to help avoid the risk of false first impressions. In the studio, cloth simulation was used to develop the design of tension membrane structures (tents) that retracted and unfurled in a series of complex movements. Fluid dynamics effects were used in the design and development of related boat dock facilities. A wind-tunnel simulation tool was used to explore the performance of the tension-membrane fabrics under varied wind loads. The visualization techniques were complemented by ¼ to ½ scale assembled components created by rapid prototyping. The use of an actual wind-tunnel further tested the prototypes in some cases. On the whole, quickly implemented special effects were the starting point for reacting to and developing some initial design concepts and served as the basis for more complete physical modeling of prototypes later on. Using animation as a design method is well established in other work (Hirschberg 06). Animation is also a helpful way to work out the step by step assembly of complex architectural form (Mark 95). The special effects tools permit a larger range of initial design alternatives to be initially considered that are subsequently narrowed down by physically based prototypes that are more predictive of real world performance.

summary	This paper is presentation of resulting physical models that were used to explore the relationship between design modeling in CAD and digital fabrication with plywood sheets. We explored a process in making tabletop models with digital fabrication machines and thin plywood sheets. Each was built from combination of predetermined wood joining techniques and structures. These models are believed work as simulation of full scale constructs that inform CAD modeling. Results illustrate the limited potential of parametric modeling and inform fabrication and assembly of design variations.

summary	This research is based on the development of a new method for surveying single and double curved surfaces using an application of an ancient perspective method for representing a picture on a complex surface. The procedure enables the user to have some detailed cross-points of a grid in order to simplify the survey operation. Another phase of the work is to take some double-pictures of the element, according of the method I shall describe in the paper. The photographs of the single element, with the projection of the regular grid, can be processed with every Image-Based Modeling Software in order to obtain – with the usual calibration methods – the digital “mapped with reticulum” model of the curved surface we are analyzing. The final step enables the user to improve the quality of the textured model, switching from the grid-textured photographs to the simple-textured one. This research is part of a more general theoretical and experimental Academic research that has the aim of studying the ancient drawing methods of in order to find some analogies with the digital technology applied to the study of architectural buildings.

title	Structural Analysis as Driver in Surface-based Design Approaches
doi	https://doi.org/10.52842/conf.ecaade.2007.109
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 109-115
summary	This ongoing research argues for novel strategies to integrate structural analysis data in an architectural design approach. Instead of a linear procedure of synthesis, analysis and post-rationalisation a synthesis/analysis loop is installed that uses structural analysis data as design driver from early on. The approach is not aiming for a pure force-driven form-finding or optimization process but regards structural performance as one design criteria among others. Equilibrium between multiple parameters is aspired instead of a single-parameter-optimum. The research is conducted by a custom-made digital interface between a 3d modelling software and an application for structural analysis of space frames structures. Surfaces are translated into meshes with supports at user-defined nodes and then exposed to its dead load in the structural analysis software. The resulting nodal deviation is feed into an algorithm that steers the appropriate reaction towards the local stresses and deviations, taking into account the mesh topology, its supports and their position in the mesh. The initial mesh is optimized in shape transformed back into a double-layer surface model in the 3d software which evolves into an interconnected two-layer space frame. An instant feedback from synthesis to analysis and vice versa is installed. Analysing techniques migrate into the realm of synthesis.

summary	In the last twenty years, computer tools have progressively enabled the modeling of buildings and cities in lesser time and cost, along with an increase in the results quality. A city modeled according to planning regulations usually present a correlation between plots and buildings dimensions. The representation of such correlation for a large number of plots requires repetitive work, thus suggesting the use of a computational tool to perform the task. Existing CAD, GIS, and VR software can generate accurate representations of the reality, but have no capabilities to simulate the impact of alternative urban regulations for large number of plots in a short period of time. CityZoom is a Decision Support System for urban planning, with a specific built-in city model, where data is represented in an object-oriented model representing the urban structure. CityZoom not only provide CAD tools, but a shell where different performance models can operate iteratively. It can simulate given urban regulations applied to a set of urban plots, as well as address environmental comfort issues such as shadow casting between buildings. Results can be displayed as tables, graphs, and in a 3D preview of the whole city or part of it. It’s also possible to export them to commercial GIS tools, to perform different data analysis. The graphical outputs make for an easy understanding of the results by laymen, an important feature for participatory planning, while the display of the correspondent numerical data enable correlations with indicators and parameters of urban quality.

summary	Rigidly foldable shells offer tremendous potential for developing kinetic architectural structures. However, the added element of motion poses new design challenges. Initially, sketchy shell geometry is constructed to reflect the intended form. Further steps involve assuring an error free folding within a range that satisfies desired functional requirements. The kinematics of a parallel topology of the shell's geometry is difficult to express algorithmically what prevents from developing of automated adjustment tools based on computational methods. The geometry can be adjusted manually based on intuitive observations; however the process is tedious, time consuming and unpredictable. This paper develops automated adjustment tools based on the intuitive approach of a human designer. The study applies the fuzzy logic formalism as a computational interface between human approach and structured adjustments to the geometry. The advantages of fuzzy logic stem from its natural ability to represent human knowledge and effectiveness in reconciling ambiguities, uncertainties and redundancies that the intuitive human approach brings along. The development steps of fuzzy logic based algorithm are presented. Performed evaluation tests and the results are discussed.
