title	Design Informatics: a case based investigation into parametric design scripting and CNC based manufacturing techniques
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for manifesting complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This designresearch approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. A pattern of points attained from this intersection: ‘the point cloud’ serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed scriptroutines, iteratively run calculations to generate steel-wire frames, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct thus enabling timely and effective construction of the conceptualized form.

title	Optimal Distribution of Architecture Programs with Multiple-constraint Genetic Algorithm
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 299-303
summary	A genetic algorithm (GA) is a search technique for optimizing or solving a problem based on evolutionary biology, using terms and processes such as genomes, chromosomes, cross-over, mutation, or selection. The evolution starts from a population of completely random individuals and happens in generations. In each generation, the fitness of the whole population is evaluated, multiple individuals are stochastically selected from the current population (based on their fitness), modified (mutated or recombined) to form a new population, which becomes current in the next iteration of the algorithm. In architecture, GAs are of special interest mainly because of their ability to address a problem offering a multiplicity of possible solutions. Contrary to other algorithms where the objective is to accommodate a manually conceived diagram, GAs are emergent procedures that evolve over time through multiple attempt cycles (i.e. generations) and therefore offer a bottom-up approach to design. In addition, by using the computational power of computers they can resolve complex interactions between multiple factors and under multiple constraints offering solutions that occasionally surprise the designer. One of the main problems in architecture today is the quantity of the information and the level of complexity involved in most building projects. As globalization and economic development has started to arise at unprecedented levels, the need for large urban developments have become commonplace. Housing projects for a few hundreds to thousands of people have started to emerge over large urban areas. In such cases, the old paradigm for housing design was the development of high rises that served as stacking devices for multiple family housing units. Such a direction was unfortunately the only way to address excessive complexity using manual design skills mainly because it was simple to conceive but also simple to construct. The unfortunate nature of this approach lies rather in the uniformity, similarity, and invariability that these projects express in comparison to individuality, discreteness, and identity that human beings and families manifest. One of the main areas of complexity that could benefit architecture is in housing projects. In these projects there is a typology of residential units that need to be combined in various schemes that will fulfill multiple functional, environmental, and economic constraints. In this paper, the design of a 200-unit residential complex on a corner of two streets in an urban context was investigated as a case study. Recent advancement in tectonics and structural engineering enables the realization of buildings in mega scales and starts to introduce another layer of complexity into the building programs. Conventional design methods relying on the preconceived knowledge based approaches are no longer reliable. Beyond the certain quantitative factors and the complexity of the problems, search occasionally enters into the unpredictable domain of the human perception. Computational approaches to design allows us to go through thousands of iterations in a second and find the solution sets beyond the reach of designers’ intuitive search spaces. Genetic Algorithm can be a potential derivative for finding optimum design solution from indeterminate search spaces constrained by multi dimensional factors.

summary	This paper describes the integration of machine intelligence into an immersive architectural sculpture that interacts dynamically with users and the environment. The system is conceived to function as an architectural envelope that might transfer air using a distributed array of components. The sculpture includes a large array of interconnected miniature structural and kinetic elements, each with local sensing, actuation, and machine intelligence. We demonstrate a model in which these autonomous, interconnected agents develop cooperative behaviour to maximize airflow. Agents have access to sensory data about their local environment and ‘learn’ to move air through the working of a genetic algorithm. Introducing distributed and responsive machine intelligence builds on work done on evolving embodied intelligence (Floreano et al. 2004) and architectural ‘geotextile’ sculptures by Philip Beesley and collaborators (Beesley et al. 1996-2006). The paper contributes to the general field of interactive art by demonstrating an application of machine intelligence as a design method. The objective is the development of coherent distributed kinetic building envelopes with environmental control functions. A cultural context is included, discussing dynamic paradigms in responsive architecture.

title	The Autopoiesis and Mimesis of Architecture
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
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 practices and techniques of fabrication. The 21st century began with the technology of art. There is a new responsiveness to the reading and understanding of digital space, which is characterized by complexity and the uncanny. 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 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 and bring forth new dreamscapes, mysterious and surreal. This implies a Freudian spatial unconscious, which can be subjected to analysis and interpretation. “Space may be the projection or the extension of the physical apparatus”, Freud noted1. Space is never universal, but subjective. A space would be a result of introjection or projection – which is to say, a product of the thinking and sensing subject as opposed to the universal and stable entity envisaged since the Enlighten. There is a spatial unconscious, susceptible to analysis and interpretation. Systematic Design: Digital media should bring about an autopoiesis. This approach calls into question traditional methods of architectural design – which replace the hierarchical processes of production known as “cause and effect” - and proposes a design process where the architect becomes a constructor of formal systems. Will the evolutionary simulation replace design? Is metric space dead? Is it replaced by the new definition of space, that of topology? The new algorithmic evolutionary conditions give architecture an autopoiesis, similar to biological dynamics. The use of algorithms in design and fabrication has shifted the role of the architect from design to programming. Parametric design has introduced another dimension: that of variation and topological evolution, breaking the authentic into the reused. Architecture now is about topology than typology, variation than authenticity, it is mimetic than original, uncanny and subconscious than merely generic. In a parallel universe, which is both algorithmic and metaphysical, the modeling machine creates a new abstraction, the morphogenesis of the “new hybrid condition”. The emphasis of the exploration is on morphological complexity. Architecture may become – paradoxically - rigorous yet more uncanny and introverted.

title	Evolving Urban Structures using Computational Optimisation
source	Proceedings of the Generative Arts conference, Milan, 2006
summary	This paper investigates the use of computer analogies for naturally inspired optimisation techniques as an aid to developing the site layout and massing for the new World Trade Centre development in Pristina Kosovo, which is being designed and developed by 4M Group architectural company, in conjunction with the Advanced Modelling Group Aedas. The development of a genetic algorithm will incorporate various techniques, that have been developed in the field of multi-objective optimisation, to create three dimensional massing models, and site layout solutions which partially fulfil the Prisina brief requirements, which are taken from specifications created by 4M Group. Genetic algorithms are based on natural evolutionary principles which are explained in this paper. It will incorporate Pareto concepts to manage the optimisation of the various objective functions. For example, these will include volume and position of units, which will ensure that the different and sometime conflicting needs of the site are balanced throughout the optimisation. This type of problem is often known as an NP-complete (non-determinate polynomial time) problem. This will provide architects and planners with a number of Pareto optimised site massing solutions as an aid to the design process. An initial investigation into the specifics of the Pristina site requirements, will be followed by an investigation into the the genetic algorithm which is created in Visual Basic for Applications (VBA) linked with AutoCAD as the graphical output of the code. The embryology (development) of the various solutions from the genetic information incorporates an ‘ant’ pheromone trail model, which simulates the action of ants during food foraging, as a tool for initial route planning within the site. Diffusion and cellular automata are used during the development of the solution to construct the massing for the site.

summary	This study describes a procedural design studio using Genetic Programming as the evolutionary mechanism and formal generation. This procedural design is integrated with a visualisation interface, which allows designers to interact and select from instances for design evolution. Evolutionary design facilitates designers in three areas: 1) diversify instances of design options; 2) inspect specific goals; 3) and enhance the possibility of discovering various potential solutions.

title	Synthetic Research

summary	Synthetic Research insinuates a relationship of a meticulous process of discovering truth contradicted against a fabricated, as in concocted, reality. It is important to recognize the logical aspect of synthetic when examining what synthetic research can provide for architectural discourse. Synthesis contrasts with analysis in that it’s primary methods involve recourse to experience; it is experience that is at the heart of synthetic research. The synthesis of theory, architectural constructions, technological artifacts and computational techniques requires experiencing the results of experimentation. Synthetic digital architecture necessitates a discovery process incorporating creation that allows for experience, be it virtual reality, full-scale prototyping or spatial creations; provided experience is a truthful one, and not disingenuous and thereby slipping into the alternate definition of synthetic.Research’s experimental arm, as opposed to the analytic, relies on tinkering - implying the unfinished, the incomplete, the prototype. Examples of this are everywhere. Computer screenshots are a strikingly literal example of synthetic research when used as a means of experiencing a process. Performance mock-ups of building assemblies are a method of synthetic research in that one experiences a set of defined performances in order to discover and redefine the project. The watchmaker craft is an exercise in research/experimentation where material properties are inherent in function and aesthetics; consider how the components interact with the environment - motion, gravity, space-time, temperature. Efficiency at this point is predominantly structural and physical. Decorative or aesthetic elements are applied or integrated in later iterations along with optimization of performance, marketing and costs.What is a architectural research? How can research synthesize the wide range of possibilities for the trajectory of architecture when engaged in digital and computational techniques? The goals, techniques, documentation and other methods of research production have a place in architecture that must be explored, particularly as it related to computation. As in other fields, we must build a legitimate body of research whereby others can use and expand upon, such that digital architectures evolve in innovative as well as prosperous paths.

title	Adaptive Generative Patterns: design and construction of Prague Biennale pavilion
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This paper describes an experimental practice-based research project that considered design process, implementation and construction of a pavilion built to be part of the Performative Space section of the International Biennale of Contemporary Art, Prague 2005. The project was conceptualized as a time-bound performative situation with a parasite-like relationship to its host environment. Its design has emerged through an innovative iterative process that utilized digital simulative and procedural techniques and was formed in response to place-specific behavioral challenges. This paper presents the project as an in-depth case-study of digital methods in design, mass customization and unified methods of production. In particular, it considers the use of Voronoi patterns for production of structural elements providing detail on programming and construction techniques in relationship to design aspirations and practical constraints.

title	La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
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.

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. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	FULL 3D STRUCTURAL ZONING OF SPACE: Using a Geometrically Related Reducer and Matrix Coupling

doi	https://doi.org/10.52842/conf.caadria.2006.x.x2d
summary	Structural zoning is the recognition of forms in spatial designs. It can be used by a structural designer to develop a structural system. This paper will start with the presentation of a proof that neither user action nor a two-dimensional approach -two existing approaches of zoning- are able to recognize all possibilities for the application of a structural design to a spatial design. Only full three-dimensional structural zoning is considered to be an appropriate instrument to give useful solutions. Two new concepts will be presented to overcome problems for three-dimensional zoning: (1) Geometrically Related Reducers and (2) Matrix Coupling. These concepts are first defined in a general form and thereafter the definitions are condensed into a practically applicable format. Both concepts are demonstrated when finding rectangular zones in spatial designs up to 44 separate spatial entities. They are programmed procedurally using the C++ computer language and are used for a comparison between structural designers and computer performance.

title	Design innovation through constraint modeling
source	International Journal of Architectural Computing vol. 4 - no. 1, 87-105
summary	In this paper we describe how constraint modeling can support design innovation. Furthermore, we lay out how constraints are employed in the construction and exploration of a model's design space. We place the approach within the context of design exploration using computational and conceptual representations of design. A review of the literature reveals that geometric, topologic, functional, and quantitative constraints are those most commonly used. For each constraint type, an example is presented drawing from several workshops and research conducted by the author. The examples range from product design, to structural design, to fabrication issues in freeform geometry. Based on the case studies, we describe how the different types of constraints can be used as design drivers and help in the exploration of solution spaces. In conclusion, we identify the need for bidirectional exercising of constraints as the next challenge in design exploration and discuss how it is relevant in particular for cross domain design.

summary	This paper describes the development of a constraint-based generative system (FSF system) to support the design of middle and high-rise apartment façades from architectural plans. Floor plan and façade designs are heavily interrelated, and, sometimes, the plan constrains the façade design during the design process. This relationship lends itself to apply constraint-based systems and we have designed the system to connect intelligently between apartment plan and façade. In our system, we define constraints into three categories: structural form, architectural style and function. We use genetic algorithm to generate plausible alternatives quickly and augmented by a constraint-based system, façades can be generated and modified much more easily in terms of real-time visual feedback for checking violence of the constraints and of dealing with updates smoothly through intelligent connecting plans to façades.

title	Towards architect-aided computing design
source	International Journal of Architectural Computing vol. 4 - no. 1, 69-85
summary	In the design process of some recent, specific architectural projects the part elaborated by computers and machines significantly grows. They could generate, optimize and produce the most complicated and complex solutions, taking over some tasks which before were the domain of architects. This article presents a project carried out by postgraduate students at Eidgenossische Technische Hochschule in Zurich, Switzerland, where such a digital design process was implemented, with all its advantages and disadvantages. The observations and conclusions gained during the work allow the author to formulate the concept of Architect-Aided Computing Design, to define some challenges for architects created by such a working method, and to present an analysis about the potential new software for architectural production.

summary	The Hylomorphic Project is a complex canopy structure, genetically evolved as a vital entity that reacts to changing data streams while configuring the architectural form. For the Hylomorphic Project, Open Source Architecture (OSA) together with structural engineer Prof. Kristina Shea and Marina Gourtovaia of Cambridge University (UK) developed genetic algorithms. Performs in eifForm software, an experimental computer-aided design system for structural synthesis, the algorithm is based in computational environments as a methodology for form finding and material expression that goes beyond the formal articulation of the computational procedure. This procedure simulates a topological condition of natural form evolution that can be consolidated according to innumerable trajectories. Seeking dynamic, flexible and continuous evolution procedures, the software provides the required conditions for this type of the design as it consists of a computational core, which is written in C, a fast low-level compiled language. The modules providing interactive access to the core and the graphical user interface (GUI), a high-level scripting language written in Python, allow for easy customization of the software according to a design task in hand.

title	Diretrizez Geométricas de Auxílio ao Processo de Projeto de Edifícios Residenciais [Geometrical Guidelines to Aid the Design of Floor Plants of Residential Buildings]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 243-247
summary	This paper discusses the basic principles of a geometric method to aid the design process of residential buildings. It makes part of the initial phases of a research whose aim is to develop a computer system to aid the sketching and evaluation of floor plant design of multi-storied residential buildings. The fundamental idea of the research is the existence of some basic patterns of floor plants that reflect the designer’s mental models in this category of building. The models are regarding the usage of the space such as forms and dimensions, the elements for the circulation and the external skins. During the design process, architects work on each one of these models to generate the sketches of the floor plant layout. Generally, the layout of an apartment in multi-storied buildings depends basically on the internal dynamics of the users without the complex relationship with the neighborhood environment as in the case of houses. In this way, it would be easier to identify, to organize and to associate the mental models of multi-storied buildings on geometric basis, which, in their turns, might be effectively used as inputs for the layout planning of new design. By applying the geometric basis, the architects may reduce the universe of feasible alternatives into a small group of heuristic solutions that can be described by using few simple guidelines. In addition to this, the geometric bases of the existing buildings might be used to build a knowledge-based system to aid the architectural design. The objective of this paper is to show some initial results of the research obtained from a survey and the case studies of form, dimensions and topology of existing buildings. To limit the scope of the discussion, only residential buildings with two to three bedrooms are considered. At first, a survey of plants of residential buildings with two and three bedrooms, in Brazil, is carried out. In the next step, the dimensions, shape, external skin perimeter, circulation system and accessibility are analyzed. Finally, typical topologies of the building are investigated.

title	FlexM: Designing a physical construction kit for 3d modeling
source	International Journal of Architectural Computing vol. 4 - no. 2, 27-47
summary	We have designed a hub and strut kit that interfaces to a 3D graphics application. FlexM is a prototype flexible physical interface for manipulating and building 3D geometry. Using the FlexM hub and strut components, designers can build and explore 3D geometry with the ease of a toy and the power of a computer. The hubs transmit the model's topology and geometry to the computer, where the model is rendered on the screen in real time. The paper reports on the iterative development of several versions of the project.

doi	https://doi.org/10.52842/conf.caadria.2006.x.j6m
summary	Folding is not only a design operation of shaping but also a philosophy theory from Deleuze (Deleuze 1988) which was adopted by architecture. Basically, folding constitutes to forming and topology, which often delivered a mathematical and philosophical expression in generating 3D architectural form. For instance, the work of Eisenman (Eisenman 2003), Libeskind and Lynn (Lynn 1998), they use folding as inspiration to explore the textural folding and bifurcation meaning in the process of form-making. While exploring the meaning of folding, their ideas are expressed by the form using computational tools. Therefore, if a suitable or inspirable tool like our Folding Space (FoS) could be available, such action –fold can be expressed further in the form exploration process.
