summary	The knowledge of latest technology that allows the development of competitive products in reduced times is crucial to guarantee a sustainable growth of the national industry. This work presents the development of a computational system for the Virtual Design of products, the VirtusCADE, which is a CAD/CAE interactive software (Computer Aided Design/Computer Aided Engineering). The VirtusCADE includes 3D geometric modeling of surfaces and solids and mesh generation. The system uses the parametric modeling of surfaces, including algorithms for determination of intersection between surfaces and for triangular mesh generation in trimmed parametric surfaces. The graphical interface is interactive and allows the direct real time manipulation of objects (lines, surfaces and solids) in 3D using the OpenGL technology. The system prioritizes the usability, implementing several graphic tools that facilitate the manipulation in 3D. The VirtusCADE contemplates the structural simulation through the Finite Element Method. The code architecture is based on oriented object programming, which allows great scaling capability for the implementation of new tools. This project has great applicability in numerical simulation of physical phenomena, such structural analysis of buildings, vehicles parts, with impact in the industries of civil construction, metal-mechanics, aerospatial, naval and automotive.

summary	One of the research ways carried out in the ARIAM-LAREA laboratory aims at giving to architects computing tools for early evaluation of structures. A particular approach uses dimensional analysis and similitude properties in order to define parameter variation laws. Such laws are illustrated by analytical cases using the theory of strength of materials. For complex structures, a heuristic is proposed to give indications of parameter variation influence on mechanical behavior. Some applications are presented for early determination of structural size and limit values, using computations by finite element method.

title	A aplicação da modelagem em elementos finitos na concepção das cascas de concreto armado [The application of finite element modeling in the design of reinforced concrete shell]
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This report examines the application of physical models and digital ones as tools in the design of reinforced concrete shells. The development of computational processes and consequently the process of analyzing the structure as the finite element method allows more complex forms to be applied in architectural projects. The research demonstrates the potential of this tool, through the analysis of contemporary projects such as the “Memorial da America Latina” of Oscar Niemeyer, with modeling of the structure in ANSYS.

summary	The aim of the following paper is to show a method of digital reconstruction and analysis of an important artifact pertaining to the Abruzzo cultural heritage, the ‘trabocco’. In fact recent software for graphics and architecture, such as CAD, graphics editor, and those dedicated to three-dimensional modeling and rendering are tools that open new opportunities in the study of cultural heritage artifacts, The more the complexity of the object to study, the more the advantages for their use. A formal and structural complexity characterize the trabocchi, pile constructions typical of the Abruzzo coast, that go back to the middle of XVII century and the subject of this study is the trabocco of Punta Turchinio, the most famous and complex of the coast. Among the digital reconstruction’s objectives there are: Increase the knowledge of the ‘trabocco’ and generate a series of information necessary to define and manage a recovery plan; to study more deeply the technologic decomposition of the four main sub-systems with related abacus of the technological elements and create static and animated graphics restitutions such as renderings and animations to understand some spatial and formal characteristics.

title	Dynamic Relaxation of Tensegrity Structures
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 553-562
doi	https://doi.org/10.52842/conf.caadria.2009.553
summary	The structural hierarchy inherent to tensegrities enables a building skin that performs on multiple levels simultaneously. While having one function in the global building mechanics, its individual components can work as self-contained systems balancing tensile and compressive forces locally within them. The behavior of elements under load is linear and thus describable analytically. When these are aggregated in a tensegrity however, the performance of the assembly as a whole is non-linear. In order to investigate further these relationships a method of dynamic relaxation will be developed. This tool allows for simulation and load analysis of a complex tensegrous network, based on the relationships between force, stiffness and dimension formulated by Young and the computational means provided by a parametric/associative modeling environment. This research investigates the possible formfinding through computational means of a double-layer tensegrity grid.

title	Material-Based Design Computation: Tiling Behavior
source	ACADIA 09: reForm( ) - Building a Better Tomorrow [Proceedings of the 29th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-9842705-0-7] Chicago (Illinois) 22-25 October, 2009), pp. 122-129
doi	https://doi.org/10.52842/conf.acadia.2009.122
summary	From natural objects to man-made artifacts, tiling is all around us: it is the act of rationalizing highly complex form by breaking it up into smaller, continuous components. If well pursued, tiled objects can be easily designed and assembled. However, a geometric-centric view of tiling, whereby a predefined form determines the shape, size, and organization of tiles, has victimized the field of digital design. This paper questions the role of tiling as rationalizing method and offers an alternative theoretical framework and technical grounding for tiling behavior: the act of generation-through-tessellation informed by material behavior. The tools developed are implemented in the design of a 3D-printed chaise lounge, using multiple materials. The technical objective is to introduce a quantitative characterization and analysis of property mapping, as it is applied to a tiling algorithm using Voronoi cell tessellation. The network of tessellated Voronoi cells is used as an element in the Voronoi Finite Element Method (V-FEM) that the author developed. Various characterization functions and geometric parameters are generated, and V-FEM is executed for plane-strain analysis of doubly curved surfaces, from which global and local responses are evaluated.

summary	Design considers function, fabrication, and aesthetics collectively. Computation is beginning to affect the competitive dynamics of design. Using algorithms, designers are exploring forms that are essentially “undrawable,” even with advanced modeling and direct manipulation techniques. Determining the appropriate functional characteristics may require the application of increasingly complex structural- and environmental-performance analysis techniques. To realize physically a design may require further geometric analysis and rationalization, and the use of complex computer-controlled fabrication techniques.

title	Performative Building Skin Systems: A Morphogenomic Approach Towards Developing Real-Time Adaptive Building Skin Systems
source	International Journal of Architectural Computing vol. 7 - no. 4, 643-676
summary	Morphogenomics, a relatively new research area, involves understanding the role played by information regulation in the emergence of diverse natural and artificially generated morphologies. Performative building skin systems as a bottom-up parametric formation of context aware interdependent, ubiquitously communicating components leading to the development of continually performative systems is one of the multi-scalar derivations of the aforementioned Morphogenomic understanding. The agenda of adaptations for these building skins specifically corresponds to three domains of adaptation: structural, behavioral and physiological adaptations resulting in kinetic adaptability, energy generation, conservation, transport and usage principles as well as material property based changes per component. The developed skins adapt in real time via operating upon ubiquitous communication and data-regulation protocols for sensing and processing contextual information. Computational processes and information technology based tools and techniques such as parametric design, real-time simulation using game design software, environmental information mapping, sensing and actuating systems coupled with inbuilt control systems as well as manufacturing physical models in collaboration with praxis form a vital part of these skin systems. These experiments and analysis based on developing intrinsic inter-dependencies between contextual data, structure and material logistics thus lay the foundation for a new era of continually performing, self powering, real-time adaptive intelligent building skin systems.

title	Rebuilding Architecture: An analysis and critical investigation practice

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

summary	This paper presents an evolutionary algorithm that draws its power from the literal interpretation of the natural system’s 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.

title	Musical Deconstruction / Reconstruction: Visualizing architectonic spaces through music
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 225-233
summary	There is a common belief that music and architecture are connected through a hidden a dimension. Both arts, when abstracted intellectually (through mathematics) or emotionally (through phenomenological experience), share a number of ordering principles, having the same notion of crescendo in sequence and progression. Many have sought to unlock this hidden dimension to create artwork that lets our souls transcend up to the heavens. There are five different methods where architects have used music in their design approach: there are those who use harmonic proportions found in musical consonances as room dimensions to create harmonic spaces, flowing into each other like musical chords (Palladio, Steven Holl); those who believe that music is ‘design in time’ use rhythmic elements of music and apply it to their vertical surfaces and structural grids (Iannis Xenakis, Le Corbusier); those who use architecture as a musical instrument experiment with sound and acoustics to create a phenomenological environment (Bernhard Leitner, Peter Zumthor); those gifted with synethsesia (stimulating one sensory preceptor with another, e.g. seeing colors by listening to music, or vice versa) use certain musical pieces as an inspiration for form generation (Wassily Kandinsky, Steven Holl); and there are those who deconstruct an element in music and reconstruct it to architectural form, highlighting common themes between both arts (Iannis Xenakis, Daniel Libeskind). These five different methods have been the topic of research of many architectural scholars using western music as reference. The question becomes what if the musical reference is changed? Classical, rock, pop, country, jazz, and blues music are very different from one another, yet they share similar foundational musical structures. One may go further and experiment with various world music as reference, which is very different than western music in terms of musical structure. Linguists and musicologists have discussed the origins of music in relation to language. They hypothesize that cognitive elements found in language are somehow carried into the region's music. This paper documents the research of the author in this topic, discussing the digital modeling applications adopted that make such an investigation possible. The interest here is exploring how the visual space is altered when the musical reference is changed, and whether properties of the musical reference are evident in the architectural visualization. The musical references will be limited to Western Classical and Arabic music.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	In experimenting with digital processes for simulating the behavior 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.

summary	In recent years, the architectural design process has witnessed a demand for professionals who can resolve the highly complex social, cultural, technological, and economical issues associated with “Sustainable Design”. At present, many designers use environmental data generated from building performance simulation applications such as “Ecotect”. The wealth of data generated from such applications is often presented in a rather complicated format through graphs and tables, relying significantly on the designer’s expertise to read, analyze, interpret and correlate these data. This paper presents a framework for developing a method that helps design students and untrained professionals to visualise and understand the implications of these environmental data during the different stages of the design process. This method mainly targets students and designers who are not fully equipped to solidly interpret these complex data sets or use them in the decision-making process. The proposed method aims therefore to present relevant analysis of the environment-related data within the context of a simple, user-friendly virtual game environment, relying on embodied agents within the game engine to trigger events and actions performed by the users, and present pertinent data subsequently.

summary	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.

title	Digital Design of High-Rise Buildings with Tessellation and Mapping

summary	A new high-rise building, when inserted in an existing urban environment, cannot have all the floor plans identical since the visual and environmental constraints change from floor to floor due to the interference of neighboring buildings, sun light, prevailing wind and noise. So how can we design a building that takes into consideration all this variables? How can digital design tools help? (DELPINO, 2014). We believe that a building like that can be designed constructing facade maps which allow a floor by floor analysis considering visual, wind, noise and sun light constraints. We believe that facade maps analysis and their superposition provide clues of how each floor plan can be built to provide comfort and to take most advantage of the view. (DELPINO, 2014). We believe that variation techniques such as tessellation and morphing can provide the formal bases for such design. We believe that digital design tools are vital both for analysis as well as for designing this type of building. (IWAMOTO, 2009, p. 35-59; MOUSSAVI, 2009, p. 42-216).

title	A Multi-dimensional Exploration of Urban Attributes by Data Mining
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 333-350.
summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

summary	Implicit in current understandings of sustainability is the presence of a closed system with the capacity of equilibration. Sustainable practices, including design practices, are therefore assumed to possess a redemptive role: design is deployed (as environmentally sustainable design, etc.) to change habits, develop new technologies and recover marginalized practices in the hope of righting the balance between the environment and human endeavours. Recent developments in experimental digital design have demonstrated non‐linear and highly complex relations between topological transformations, material change, and the temporal dimension of forces. More importantly, this method of design is bottom‐up, because it does not rely on design solutions presaged by conventions, or restricted by representation, but is emergent within the performance of computational design itself. We argue that digital design processes need to move beyond the flux of determinates and solutions in equilibrium, towards a radically continuous but consistent production, which is in effect, an expression of sustainable pedagogy. The role of emergent digital techniques has significant impact on the methods in which computation is utilized within both practice and academic environments. This paper outlines a digital design studio on sustainability at the University of Tasmania, Australia that uses parametric modelling, digital performance testing, and topological morphology, concomitant with actual material fabrication, as a potent mode of collaborative design studio practice towards a sustainable design pedagogy.

title	How much is it? About the use of the element method in conjunction with optimization techniques

summary	It is obvious that the preparation and compliance with cost estimates for a proposed architectural design is indispensable for successful realization of building projects. A variety of methods exists that can be used by the architect to achieve this objective. However, most of these methods are regularly not used until the design is completed. In many cases this procedure leads to cost overruns. Hence, our paradigm is to estimate the total building costs prior to the generation of detailed designs and thus use the costs of building elements as design parameters right from the beginning to produce design solutions which entail the least possible costs. For this purpose we invert the customary process through the use of building element costs as a means for the automatic generation of monetarily assessable design solutions. For various reasons we concentrate on the design of housing projects. The methodology however, can be adopted to any other kind of building typology.
