summary	This proposal addresses the following topic of a doctoral thesis in progress: The Evolution and Development of Digitized Processes for the Research and Maintenance of Small Town Patrimonies, School and Architecture and Urban Design, University of Buenos Aires, co-directed by architects A. Montagu and R. Gutierrez. The research has been based on the town of Mercedes, Province of Buenos Aires, Argentina, symbols of Buenos Aires.s cultural heritage. At this stage, we are looking for alternative methods to support a project of patrimonial preservation that would help define future landscapes of small towns, and, at the same time, would have minimal or positive environmental impact. This analysis proposes reflexive studies of the paradigms affecting the environment and the feasibility of the project, with the intention of utilizing the concept of .ecoproject.. Therefore, the crucial assistance of specific digital systems, from which evolution is analyzed, supports and enhances the efficiency of the proposed goal. New and broad research opportunities are opening up in this field.

title	Artificial intelligence and emergence in architecture: A multi-agent based model for design processes
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	The purpose of this paper is to provide an alternative approach to traditional design process formulation and elaboration. In contrast to traditional models of design process fundamentally defined by the abstract manipulation of objects, this study recognizes that the resources available for rethinking architecture are to be found in a reformulation of its theory and practice. This reformulation should be based on non-linear design processes in which dynamic emergence and invention take the place of a linear design process fixed on a particular object evolution. Design is possible to be defined in two different and commonly confused ways; one as the process of designing or design activity and the second as the product of designing. In this study, we are concerned with design as a process to emphasize the misconceptions, derived from studying design products solely. Therefore, we propose a change from a design knowledge based on objects to a one focused on design as a network of processes.

summary	The course Alternatives of Design is part of an integral viewpoint that aims to prepare architects from the Master Studies Department in Computing in Architecture (LUZ), in two ways: first, by expanding their perspective about potentialities of using new digital technologies in architecture, and second, by qualifying them to apply this acquired theoretical knowledge in their professional environment. The objectives of this paper are to describe the program of this course and to show products (2003), from the introductory to the final presentation of Virtual Museums of Interactive Sculptures, orientated and supervised both at site and at a distance through the Internet. As a result of this experience, a sample was obtained of virtual museums. design and modelling that illustrates what could be understood as virtual architecture with high degree of interaction, looking for the evolution, motivation and teamwork to incorporate virtual reality non-inmersive technologies in this new architectonic approach.

source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 47-54.
summary	We consider the problem of automating the recoloring of designs whose “originals” are defined using color look-up tables. Given a digital image , we assume for each pixel of there exists an integer index such that . If is a color look-up table of size , we say image is colored by if each pixel is assigned color . Given a map from to itself, we recolor by assigning to each pixel the color . We are able to evolve the recoloring maps by representing them as -tuples. We automate their evolution by applying multi-objective optimization. Examples of recolorings of designs that were originally in color and originally in black and white are given. Keywords. Color look-up table, image recoloring, genetic algorithm, evolutionary multiobjective optimization.

title	Architectural Representation Software: a Design Tool
source	International Journal of Architectural Computing vol. 2 - no. 3, 403-422
summary	In the last decades, design processes have been approached with absolutely new representation techniques: digital media. This new tool was naturally incorporated to the architectural task not only in universities but also in Architectural offices. However, their evolution and utilization have been so sudden that their impact on the design object could not be properly assessed. Simply they stated to be used by translating analogical representation techniques into the digital media. In the Latin American context, in which the media interaction paradigm has not yet been completely established within universities and teachers, this work presents an exploration of the underlying ideas contained in the architectural representation software, as well as a series of exercises intended to teach how to use digital media as a design tool, instead of teaching how to use them as a mere representation tool.

title	Zero-waste, Flat Pack Truss Work: An Investigation of Responsive Structuralism
doi	https://doi.org/10.52842/conf.acadia.2011.138
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 138-143
summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models.This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. A truss is defined as: “A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members.” (Allen and Iano 2004)Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes.

title	GEOMETRY AND ARCHITECTURE: NURBS, DESIGN AND CONSTRUCTION
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 135-139.
summary	Geometry regarded as a tool for understanding is perhaps the part of Mathematics which is the most intuitive, concrete and linked to reality. From its roots as a tool to describe and measure shapes, geometry as ‘the space science’ , has grown towards a theory of ideas and methods by means of which it is possible to build and study idealised models, not only from the physical world but also from the real world. In graphic architecture thought, geometry usually appears as an instrumental support for project speculation. Geometric procedures are presented as representational resources for the graphic testing of reflection and for the exposition of ideas in order to build a logical order as regards representation and formal prefiguration. The fast rise of computing in the last decades has made it possible for architects to work massively and in a graphic and intuitive way with mathematical representations of tridimensional geometry, such as the NURBS . These organic surfaces of free shapes defined by vectorial curves have allowed access to a rapid generation of complex shapes with a minumum amount of data and of specific knowledge. The great development of modelling achieved by the digital media and the limitations in the technical and building areas and in the existence of materials which are coherent with the resultant shapes reveal a considerable distance between the systems of ideation and simulation characteristic of the computing era and the analogous systems of production inherited from the slow industrial development. This distance has been shortened by CAD/CAM systems, which are, however, not very accessible to the architectural field. If we incorporate to the development of these divergent media the limitations which are distinctive of the material resources and procedures of the existent local technology, the aforementioned distance seems even greater. Assuming the metaphor of living at the threshold of two ages (industrial-computing, analogical-digital, material-virtual) and the challenge of the new conceptual and operational tools in our field, we work in the mixture, with no exclusions or substitutions, proposing (by means of the development of informational complements) some alternatives of work to approach the issue under discussion from the Architecture Workshop.

summary	This paper presents an account of our research and development of processes providing seamless transition from design to fabrication. The narrative of our design, development, and prototyping experi¬ments spans seven years, including our current project, the Trusset software/structural system. Trusset is a combined building system and agent-based software design tool. The building system is based on a differential space-truss designed for fabrication entirely with computer numerically controlled (CNC) linear cutting devices, such as laser cut¬ters or three-axis mills. The software component is a set of agent-based design tools for developing surfaces and envelopes formally suitable to be built using the space-truss structure. Developed in parallel, the soft¬ware and building components combine within the Trusset system to provide a seamless pipeline from design to fabrication and assembly. The story of the development of software components and structural system, leading to the Trusset, act as a means of discussing the larger issues framing the research: the potential pitfalls and benefits of design and fabrication integration via the computer.

title	An Energy Centric Approach to Architecture: Abstracting the material to co-rationalize design and performance
doi	https://doi.org/10.52842/conf.acadia.2008.072
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 72-81
summary	This paper begins by exploring matter as an aggregated system of energy transactions and modulations. With this in mind, it examines the notion of energy driven form finding as a design methodology that can simultaneously negotiate physical, environmental and fabrication considerations. The digital workspace enables this notion of form finding to re-establish itself in the world of architecture through a range of analytic tools that algorithmically encode real world physics. Simulating the spatial and energetic characteristics of reality enables virtual “form generation models that recognize the laws of physics and are able to create ‘minimum’ surfaces for compression, bending [and] tension” (Cook 2004). The language of energy, common in engineering and materials science, enables a renewed trans-disciplinary dialogue that addresses significant historic disjunctions such as the professional divide between architects and engineers. Design becomes a science of exploring abstracted energy states to discover a suitable resonance with which to tune the built environment. ¶ A case study of one particular method of energy driven form finding is presented. Bi-directional Evolutionary Structural Optimization (BESO) is a generative engineering technique developed at RMIT University. It appropriates natural growth strategies to determine optimum forms that respond to structural criteria by reorganizing their topology. This dynamic topology response enables structural optimization to become an integrated component of design exploration. A sequence of investigations illustrates the flexibility and trans-disciplinary benefits of this approach. Using BESO as a tool for design rather than purely for structural optimization fuses the creative approach of the architect with the pragmatic approach of the engineer, enabling outcomes that neither profession could develop in isolation. The BESO case study alludes to future design processes that will facilitate a coherent unfolding of design logic comparable to morphogenesis.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London.

summary	This paper presents a pedagogical approach to explore the relationships between time and space by using digital media. Based on a pedagogical model called e-Space proposed by Lai (2004), we apply motion as a spatial issue to approach this study. Through integrating with the characteristics of digital media, students are encouraged to evolve architectural space and form by decomposing, re-organizing, interpreting and realizing the spatial composition. Simultaneously, diverse digital media applications integrated with design thinking in a design process enables students to bridge two design spaces - physical and virtual. This process introduces the students to a new approach of design-creation and form finding. Finally, we use an advanced digital media course as an example to understand the impacts of the pedagogical approach. The students’ outcomes are also reported in this paper

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	By incorporating parametric surfaces and spline entities into the shape modeling computer systems, new design and production graphic tools have been created in the conceptual and poetic field of architecture; thus allowing an intuitive approach to the fast production of complex shapes with a minimum amount of data and specific knowledge. The analogous production systems (constrained by the material resources and constructive procedures present in the local existing technologies) are challenged by design and virtual simulation systems, suggesting new relationships between the architectural features and their representation: the creation of a symbolic and dynamic information space where the representation affects the identity of what is being represented. Taking into account this current challenge mentioned above, we have decided to work in the mixture, without reciprocal exclusions or substitutions, proposing some work alternatives to approach the issue under discussion in the Architecture Workshop.

title	CONTINUITY IN SPATIAL SURFACES FOR INDUSTRIAL DESIGN
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 97-104.
summary	The purpose of this enquiry was to verify the way in which CAD systems and their tools for visual surfaces analysis interact with morphological knowledge in the determination of continuity in products of industrial design. We acknowledge that geometrical knowledge is necessary but not enough for working with this attribute of form in everyday objects, where cultural factors are involved. Geometry establishes a progressive range of continuity of surfaces that involves the concepts of position, tangency and curvature. In product design we find different degrees of continuity that not necessarily follow this idea of increment. What is understood as discontinuous in products in most cases is geometrically continuous. The control of smoothness in the shape of objects, is influenced by the way in which the form was created and by the different communicational, functional and technological elements that identify a product of industrial design. Subtlety in the suggestion of form, by means of the regulation its continuity, is what turns it suggestive through design. We consider that the development of the geometry of digital drawing systems in three dimensions should be an integrating process, where CAD developers and designers work closer in order to potentiate both activities.

summary	The distinction between the artificial and the natural has been increasingly challenged as a result of advances in genetics, microbiol¬ogy, and robotics. Beginning with the molecular assemblage of organic systems into complex micro-surfaces and structures, and expanding into the realm of the macro landscape, our understanding of the term Synthetic must be revised. What is the relationship between the component (or part) and the whole, when confronted with the Synthetic? Digitally mediated fabrication technologies, combined with a renewed interest in topology and (bio)logical form, serve to challenge our preconceived notions of space and form. This inquiry will attempt to explore the relationship between traditional assemblies produced by hand, and the production of complex forms through digital rapid prototyping. The impact of D'Arcy Thompson's On Growth and Form will be considered both as a historical juncture and a contemporary source of knowledge for the exploration of new assemblages inspired by topology and biology. In particular, the organic micro-surfaces depicted in France Bourély's Hidden Beauty will be explored, in comparison with the mathematical development of organic forms inspired by Periodic Minimal Surfaces. The analysis of emerging forms and assemblages based on the notion of the Synthetic will be compared with the Organic, and considered within the context of twentieth century art and sculpture. An attempt will be made to establish new modes of inquiry for combining digital and physical explorations of space and form, influenced by advances in micro-scale structures, complex surfaces, and the history of organic form in art.

source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 228-237
summary	The paper presents a new modeling technique for architectural design. Rind modeling provides for the easy creation of surfaces resembling peeled and punctured rinds. We show how the method‘s two main steps of 1) creation of a shell or crust 2) opening holes in the crust by punching or peeling can be encapsulated into a real time semi-automatic interactive algorithm. We include a number of worked examples, some by students in a special modeling workshop that demonstrate the ease with which a large variety of intricate rind shapes can be created. Rind modeling method allows us developing a user-friendly tool for designers and architects. The new tool extends the abilities of polygonal modeling and allows designers to work on structured and consistent models for architectural design purposes. Rind modeling gives architects and designers a processing flexibility. It can be used in conceptual modeling during the early design phase. It can also be efficiently used for creating variety of shell structures for architectural design.

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	This paper will report on a generative performative modeling approach that engages architects and structural engineers in close dialog. We focus on knowledge shared between architects and engineers to apply the Finite Element Analysis based structural design technique Evolutionary Structural Optimization [ESO] as a way to understand or corroborate the performance factors that are significant in determining architectural form. ESO is very close conceptually to the dynamical system of matter and forces of growth itself. It has parallels both mathematical and metaphorical with natural evolution and morphogenesis so it has been poignant to apply the approach to a formal architectural case study in which the generative influence of these processes is inherent.

summary	The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.
