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	VIRTUAL ENVIRONMENTS FOR THE EVALUATION OF HUMAN PERFORMANCE: Towards Virtual Occupancy Evaluation in Designed Environments (VOE)
doi	https://doi.org/10.52842/conf.caadria.2006.x.j9t

summary	Analyzing and evaluating designs for modifications to suit the requirements of human performance is typically performed only after the architectural spaces and structures have been built and used, a process that is known as retrofit or post-occupancy evaluation. For people with disabilities, there is a special need to overcome this problem by evaluating the suitability of their home environments before the construction phase. Our work introduces a new methodology in which virtual reality (VR) is used for virtual pre-occupancy environmental evaluation (VOE). Our study demonstrates the potential of the VOE concept by developing an interactive living environments model to evaluate human performance before the construction phase. This paper presents an interactive virtual environment, ‘HabiTest’, as well as the initial results of a usability evaluation of this interactive environment.

title	Grammar Representations to Facilitate Style Innovation - An Example From Mobile Phone Design

summary	Previous research in generative design has suggested that shape grammar transformations could be used for developing new design styles by the systematic modification of grammars that encode existing styles. Our research explores how such grammar transformations can be facilitated to be responsive to changes in design style requirements. For this it is important to consider the structure and organization of rules, as well as the description of the styles of designs generated by a grammar. Using an example of mobile phone design, we outline the development of a flexible grammar structure that is conducive to transformations. The grammar is augmented with a style description scheme based on the concept of semantic differential to map the style characteristics of grammar components. These measures could be significant for driving purposeful grammar transformations for style adaptation and innovation.

title	The Architectural Cinematographer: Creating Architectural Experiences in 3D Real-time Environments
source	International Journal of Architectural Computing vol. 4 - no. 4, pp. 71-90
summary	This paper addresses the problem of creating new navigation paradigms for experiencing architectural designs in 3D real-time environments. The exploration of techniques other than still images or fly-through animations is complex and manifold, and requires the understanding and skills of many disciplines including cinematography, computer programming, architectural design and communication of 3D space. In this article, we present the Architectural Cinematographer (AC), a first step towards new navigation paradigms for real-time interactive virtual environments that are intended to enhance architectural walkthroughs with interactive camera effects. The AC is a fully developed modification (mod) of the game UnrealTournament2004™ using the Unreal™ game engine and relies on the notions of architectural concepts, cinematographic techniques and game level design to structure the virtual environment (VE) content in a way that facilitates a perception of design qualities in virtual architecture. AC addresses the current lack of either software or a structured approach to facilitate this in real-time architectural visualizations.

title	Shape Grammar of Geometric Islamic Ornaments
doi	https://doi.org/10.52842/conf.ecaade.2006.290
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 290-297
summary	Shape grammars are the algorithmic systems used to analyze existing designs or create new ones. In spite of using text or symbols to express abstract representations, shape grammars aid to create novel designs through computational effort with shapes and rules. Many probabilities of rule selections and applications of these rules may generate emergent design solutions or create new design objectives. This paper aims to present the characteristics, shape grammar rules and historical background of geometrical ornaments in Islamic culture and to point out the possibilities of mathematics of symmetry. The knowledge presented in this paper can be used to generate new depictions and to gain new application areas like typography, wallpaper, landscape, façade design, tiling, jewelry, and textile designs. Even, these types of shape grammar studies can be used to open a novel approach as in Jean Nouvel’s “Arab World Institute” in Paris. The role of shape grammar analysis of geometrical Islamic ornaments explained in this paper is to increase the efficiency of architectural design education by facilitating the formal understanding of historical patterns. Novel use of shape grammars in education can enrich the designer’s ability to generate original designs. In this paper variants of Islamic ornaments are created with a CAAD program. A selected geometrical bezeme (ornament) from Islamic ornamental design is generated by encoding with a computer programming language. According to the generated bezeme, interaction scenario is as follows: Computer has the main control over grammar application. Only, some of the rules can be selected by the user. Varieties of this ornament are generated randomly through their line weight, line colors, filling types and filling colors. The shape grammar rules outlined in this paper are simple, but the resulting figures can be very inspiring. Furthermore, the endless potential for future design innovations is unlimited.

summary	This research presents the new orientation of the combination of digital modelling with generative programming and joint method of traditional wood structure for manipulating Rapid Prototyping to explore the assembling of free form objects. The presenting of the example indicates that the edition of Maya scripts defines the purpose of design. Through the discussion on scripts developing the assembly of the free-form objects of frames and surfaces and through the achievement that RP produces and examines objects, we bring out the possibilities of the new form developed from the old structure and illustrate how to develop our hypothesis. The developed result could provide the possible new way for free-form assembly. We expatiate our research process and final achievement and provide a new thinking direction in the education field.

title	Synthetic Dissemination
doi	https://doi.org/10.52842/conf.acadia.2006.302
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 302-303
summary	Synthetic Dissemination, within the context of architecture and information culture, offers seemingly contradictory possibilities. The ends of dissemination and synthesis are at odds. The purpose of the former being diffusion and distribution, and the byproduct of the latter being quite the opposite - namely the combination and association of information into a coherent whole. The conjoining of dissemination and synthesis implies these two contradictory operations can operate in a symbiotic or complementary manner.Relative to architecture and design the combination of dissemination and synthesis is potentially profound. The marriage of synthesis and dissemination presents a possibility that the method of distributing information could be, or have embedded within it, a synthetic process. In the simplest sense synthetic dissemination implies that the tools for design and synthesis could be the same as tools for documentation and dissemination; or more specifically that the fluidity and creativity of design software could be coupled with the practicality and meticulousness of building information modelers (BIM). More abstractly synthetic dissemination implies that the means of encoding and distributing information could propagate design. Architects have readily adopted digital tools for encoding and presenting their ideas, but have not fully recognized how the informational structures of these applications promote or hinder design. Developments in the information architecture of D software, such as the shift from geometrically based data structures to procedurally based directed action graphs (DAG) as seen in Maya and DMax, have opened up innovative methods of architectural design. Each new change in the information architecture of design software ushers in new approaches to design, raising the question - how does the production and storage of information affect design? More broadly, how can the tools of dissemination facilitate synthesis?

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.

summary	The choice of a chord and its execution should be regarded as a must and not left to arbitrary wish or superficial speculation. (Johannes Itten, 1961) The paper describes a modular concept for the IT-support of planning practice using BIM (Building Information Modelling) and a parameterized building model. The platform used is the modularized software concept for architectural planning in existing built contexts (prototype software FREAK). The current progress in the development of a reasoned support of planning tasks is described in this paper in more detail. The system consists of a series of software prototypes which are linked to the BIM, utilize the specific data within and demonstrate the value of a consistent and extendable CAD-model. The “Colored Architecture” software prototype is one such design-support module of the software platform and enables the designer to experiment with the parameters colour, light and materials in architectural space. This module supports experimentation, assessment and realization of colours and materials in the architectural design process on a new quality. For instance, the integration of “live radiosity” light simulation allows a qualified and interactive assessment and evaluation of colours and materials in near-real lighting conditions. The paper also details further software prototypes, modules and concepts including building surveying and the design of self-supporting domed structures.

title	Shape Change in Responsive Architectural Structures: Current Reasons & Challenge
doi	https://doi.org/10.52842/conf.acadia.2006.251
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 251-260
summary	Shape control within architectural structures is a natural extension to the practice of engineering and architectural design. The knowledge needed for it’s development builds upon two well understood foundations: 1) the long existing knowledge that building performance and function are intimately connected to the shape of built spaces; and 2) the relatively new idea that embedded computational systems may be employed to control devices in useful and beautiful ways. When combined, each type of knowledge can be used to further architecture and engineering at both theoretical and methodological levels. Structural shape control is of major interest within architecture because it is the primary ingredient needed to produce building envelopes that change shape. Structural shape control also currently represents a major technological and methodological stumbling block for architects, posing many challenges that have theoretical and practical origins. Theoretically, responsive architectural structures demand a re-evaluation of existing notions of space making. Practically, these systems demand a re-evaluation of construction and design methodologies across both engineering and architectural practice.

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	The focus in our elective course for Master Students of Architecture is the following: in parallel to a more traditional way of analysing urban structures, how can the application of multimedia technology, networking and the integration of interactive computer applications lead to a different approach? The objective of our teaching and research project is to find out in what ways urban structure and specific features of a city can be represented by interactive interfaces and the use of CNC technology. Our attitude is based on small-scale approach: the sum of these microanalyses gives us the broader picture, the system or mechanisms of the city. We do not dive into the city but emerge from it. This reflection leads to a new understanding in the organisation of complex urban structures, highlighting and revealing different connections and relationships, thus giving a different final image.

title	Teaching parametric design in code and construction
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 158-161
summary	Automated manufacturing processes with the ability to translate digital models into physical form promise both an increase in the complexity of what can be built, and through rapid prototyping, a possibility to experiment easily with tangible examples of the evolving design. The increasing literacy of designers in computer languages, on the other hand, offers a new range of techniques through which the models themselves might be generated. This paper reviews the results of an integrated parametric modelling and digital manufacturing workshop combining participants with a background in computer programming with those with a background in fabrication. Its aim was both to encourage collaboration in a domain that overlaps both backgrounds, as well as to explore the ways in which the two working methods naturally extend the boundaries of traditional parametric design. The types of projects chosen by the students, the working methods adopted and progress made will be discussed in light of future educational possibilities, and of the future direction of parametric tools themselves. Where standard CAD constructs isolated geometric primitives, parametric models allow the user to set up a hierarchy of relationships, deferring such details as specific dimension and sometimes quantity to a later point. Usually these are captured by a geometric schema. Many such relationships in real design however, can not be defined in terms of geometry alone. Logical operations, environmental effects such as lighting and air flow, the behaviour of people and the dynamic behaviour of materials are all essential design parameters that require other methods of definition, including the algorithm. It has been our position that the skills of the programmer are necessary in the future of design. Bentley’s Generative Components software was used as the primary vehicle for the workshop design projects. Built within the familiar Microstation framework, it enables the construction of a parametric model at a range of different interfaces, from purely graphic through to entirely code based, thus allowing the manipulation of such non-geometric, algorithmic relationships as described above. Two-dimensional laser cutting was the primary fabrication method, allowing for rapid manufacturing, and in some cases iterative physical testing. The two technologies have led in the workshop to working methods that extend the geometric schema: the first, by forcing an explicit understanding of design as procedural, and the second by encouraging physical experimentation and optimisation. The resulting projects have tended to focus on responsiveness to conditions either coded or incorporated into experimental loop. Examples will be discussed. While programming languages and geometry are universal in intent, their constraints on the design process were still notable. The default data structures of computer languages (in particular the rectangular array) replace one schema limitation with another. The indexing of data in this way is conceptually hard-wired into much of our thinking both in CAD and in code. Thankfully this can be overcome with a bit of programming, but the number of projects which have required this suggests that more intuitive, or spatial methods of data access might be developed in the future.

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

source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 161-168
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.

summary	A new notion of participation is at stake with advances in technologically mediated work environments. The digitally mediated e-design studio has been around since the mid-1990’s and has been employed in various forms in disciplines including architecture/engineering/construction (AEC), industrial design, and the automotive industry. Insufficient bandwidth and insufficiently powerful, crudely coordinated tools resulted in distributed task-based modes of collaboration that did not allow full participation by members of the distributed design team. At the very least, the present “second generation” network severely limits the applications, tools, and modes of communication that can be used in data and visualization intense design scenarios. The emergence of Service Oriented Architectures and User-Controlled LightPaths (“intelligent infrastructure”) herald the beginning of a new age where fully participatory multi-site design may become possible. The networks, visualization & communication tools, Service Oriented Architecture & Web Services, work protocols, and physical site designs of the Participatory Design Studio (PDS) being developed by the authors will constitute one of the first working examples of this future. This paper will briefly outline the “mise en scène” or staging of the technical configuration of the Eucalyptus project; observations and results from the creative activity of the PDS in the context of two case studies; and speculate on the implications for design activity, pedagogy, and a more robust mode of participation.

summary	The paper demonstrates the need for advanced models of representation for circular dependency networks common in design problems that deal with multiple constraints. Constraints in a design problem are generally perceived as limitations to design exploration. The careful construction of constraint relationships can help to turn constraints into design drivers for the problem instead. Closely related to the notion that new goals may emerge from creating designs is the idea that one goal of planning may be the design activity itself (Simon 1981). The interplay of many constraints can lead to circular dependencies that make design exploration a challenge as any change causes ripples throughout the entire design construct. D’Arcy Thompson (1942) describes form as a diagram of forces. The construction of design representations that reflect such dependency networks pose a challenge and are far from exact matches of the task environment (Simon 1981). The paper proceeds in mapping these abstract observations of the circular dependencies in the design process to a chair experiment from design to fabrication giving detailed descriptions of the interdependencies of material, fabrication and aesthetic constraints. The experiment shows how those constraints were instrumental in achieving the aesthetics of the full scale prototype.

title	Movement in Architecture - An Analytical Approach Towards Organic Characteristics

summary	Nature is the fundamental and recurring inspiration of organic architecture. Living organisms, both in their outward forms and in their inner structures, offer endless ideas and concepts for design. Organic architecture works with metamorphosis (the process of growth and change), the notion of “design from within”. Why should architecture be lifeless and static? Here, Movement, a unique quality of living organism is used to contribute to architecture. We cannot make a new life but we can take the characteristics to make changes in our environment, seeking not to imitate nature’s appearance, but instead to imaginatively apply its profound principles. The focus of this paper is to examine and categorize the different kinds of movement that exist in nature, understanding how their purpose can be effectively used in architecture. The topic explores techniques of living organisms used for function and defense and discusses possible implementation in architecture. Movement has the potentiality to introduce flexibility, ecological efficiency and building defense through deformable, transportable, shape shifting and morphing forms.

title	Evolution or Revolution: is digital conceptual design the way forward for Architects?

summary	This research investigates architectural conceptual design and discusses its recent historical, philosophical and theoretical development within the overall architectural design process and attempts to establish an objective definition more tuned to current thinking and advancement in technology. It also evaluates the various traditional and information technology (IT) tools available to the designer and establishes their relationship to the conceptual design process in order to identify if any of these tools, in particular the IT tools, have a role to play in the practice and the enhancement of the conceptual design process. A survey of Scottish practicing architects (small to medium size practices) was undertaken to validate the results of the investigation. The results seem to suggest that IT tools are not essential to the conceptual design process but that they are very well capable of enhancing the creativity and speed of some aspects of it. They also suggest the existence of an inherent resistance amongst Architects / designers to utilising these tools in conceptual design. It is, furthermore, identified that if practitioners were to encompass new working practices and acquire new skills, IT tools could also provide powerful new modes of communication with the client. A correlation between the size of the practice and the degree of exposure and experience of IT tools was also established. To test some of the above findings, a design studio experiment was undertaken where half of the students adopted digital tools, utilising SketchUp software and digital sketchpads, whilst the others adopted traditional tools for the conceptual design part of their projects. No attempt was made to gauge the quality of the actual designs produced. The results indicate that the SketchUp group rated their conceptual design experience higher in terms of efficiency, flexibility and communication. The control group, who had dominantly adopted traditional freehand sketching, were impressed by the outcome from the SketchUp group. All student who answered the questionnaire, both SketchUp and control groups, said they would consider adopting some form of 3D sketching in the future.

title	Digital Tools for Sustainable Revitalization of Buildings - Finding new Utilizations through Destructive and Non-Destructive Floor Space Relocation
source	Proceedings of the International Conference on Urban, Architectural and Technical Aspects of the Renewal of the Countryside IV., Bratislava, May 2006
summary	In 1845 Edgar Allan Poe wrote the poem “The Raven”, an act full of poetry, love, passion, mourning, melancholia and death. In his essay “The Theory of Composition” which was published in 1846 Poe proved that the poem is based on an accurate mathematical description. Not only in literature are structures present that are based on mathematics. In the work of famous musicians, artists or architects like Bach, Escher or Palladio it is evident that the beauty and clarity of their work as well as its traceability has often been reached through the use of intrinsic mathematic coherences. If suchlike structures could be described within architecture, their mathematical abstraction could supplement “The Theory of Composition” of a building. This research focuses on an approach to describe layout principles of existing buildings in the form of mathematical rules. Provided that “design” is in principle a combinatorial problem, i.e. a constraint-based search for an overall optimal solution of a design problem, two exemplary methods will be described to apply new utilizations to existing buildings through the use of these rules.

title	Designing with Machines: solving architectural layout planning problems by the use of a constraint programming language and scheduling algorithms

summary	In 1845 Edgar Allan Poe wrote the poem “The Raven”, an act full of poetry, love, passion, mourning, melancholia and death. In his essay “The Theory of Composition” which was published in 1846 Poe proved that the poem is based on an accurate mathematical description. Not only in literature are structures present that are based on mathematics. In the work of famous musicians, artists or architects like Bach, Escher or Palladio it is evident that the beauty and clarity of their work as well as its traceability has often been reached through the use of intrinsic mathematic coherences. If suchlike structures could be described within architecture, their mathematical abstraction could supplement “The Theory of Composition” of a building. This research focuses on an approach to describe principles in architectural layout planning in the form of mathematical rules that will be executed by the use of a computer. Provided that “design” is in principle a combinatorial problem, i.e. a constraint-based search for an overall optimal solution of a design problem, an exemplary method will be described to solve problems in architectural layout planning. Two problem domains will be examined: the design of new buildings, as well as the revitalization of existing buildings. Mathematical and syntactical difficulties that arise from the attempt to extract rules that relate to the process of building design will be pointed out. To avoid conflicts relating to theoretical subtleness a customary approach has been chosen in this work which is adopted from Operations Research. In this approach design is a synonym for planning, which could be described as a systematic and methodical course of action for the analysis and solution of current or future problems. The planning task is defined as an analysis of a problem with the aim to prepare optimal decisions by the use of mathematical methods. The decision problem of a planning task is represented by an optimization model and the application of an efficient algorithm to aid finding one or more solutions to the problem. The basic principle underlying the approach presented herein is the understanding of design in terms of searching for solutions that fulfill specific criteria. This search will be executed by the use of a constraint programming language, which refers to mathematical as well as to integer and mixed integer programming. Examples of architectural layout problems will be presented that can be solved by the use of this programming paradigm. In addition to this, a second programming approach resulting from the domain of resource-allocation has been followed in this research. It will be demonstrated that it is as well possible, to aid architectural layout planning by the use of scheduling algorithms.
