summary At a time when requirements on the quality of the built environment are increasingly becoming explicit and specific, computer technology promises the ability to analyse and evaluate buildings during the design process. The computer can extract the necessary information from conventional geometric representations, generate comprehensive descriptions of the aspects to be analysed and use these to arrive at precise and accurate results that can be represented visually. Visual representations facilitate comprehension of the analyses and of their results because of their agreement with our predominantly visual perception of the built environment. The consequent close correspondences between geometric design representations and the visual representation of analyses and evaluations allow direct correlation of the results with the design as a whole. Such correlation is instrumental for imposing explicit and justifiable constraints on the further development of a design. One good example of visual analyses is daylighting. In many drafting and modelling programs a viewing point can be set on the basis the sun’s height and azimuth. The projection returned reveals the surfaces that are directly lit by the sun. In other programs the sun’s height and azimuth can be used to position a light source with parallel rays. This source gives rise to shading and shadows that correspond to the ones produced by the sun. In addition, several programs can calculate the position of the sun and hence the viewing point or the light source on the basis of the date, the time and the geographic coordinates of the place. The availability of computer-aided daylighting analysis has obvious advantages for practice. Efficiency and reliability of the analysis increase, while flexibility is superior to analog simulations. Unfortunately automation of daylighting analysis may also impede understanding of underlying principles, that is, of the issues at the focus of architectural education. Explaining how the analysis is performed and why becomes thus a necessity for computer-aided design education. Exercises that aim at more than just learning and using a computer program can enrich the student’s understanding of the analysis and its results. The efficiency and flexibility of the computer facilitate the study of aspects such as the comparison of local apparent time, local mean time, standard time and daylight saving time and their significance for daylighting, solar heating and cooling patterns and possibilities. Sundials with their explicit correspondence to solar movement can be instrumental in this respect. The efficiency and flexibility of the computer also support the investigation of the techniques by which the daylighting analysis is performed and explain the relationships between projective theory, sciagraphy and computer graphics. A better understanding of the principles and techniques for daylighting analysis has a generally positive influence on the students’ learning of the daylighting analysis software and more significantly on their correlation of daylighting constraints with their designs. This leads in turn to increased flexibility and adaptability of the designs with respect to daylighting and to a conscious and meaningful exploration of variations and alternative solutions.

title A Visualization Model for External Shading Devices Performance at the Early Design Stage
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Windows are used for the visual connection between indoors and outdoors, ventilation and daylight of our interiors and for the reduction of our heating energy through solar energy utilization. This solar energy, however, is often so intense that counter measures should be taken in order to maintain comfortable indoor conditions. Air conditioning is one counteraction. In order to reduce the cooling loads, it is highly recommended to use shading devices. When shading devices are applied in combination with the glass they can modify the thermal effect of windows to a very great extent. The most effective shading devices are exterior types such as overhang, fins and exterior venetian blind. The effectiveness of an external shading device depends on its geometry, sun path, and the orientation of the building. These factors are interrelated dynamically, it is extremely difficult to predict intuitively how the shadow is cast by the external shading device on the window. Due to the inherent complexity of calculation for shadow casting, building designers to fail often integrate them into energy-efficient building design. Since computer graphics can be a powerful visual communication tool, the above problem might be solved through a computerized graphical interface in the early design stage. The research described in this paper involves the development of a computer program which aims the following objectives: (1) to facilitate the description of a external shading device's geometry through an integrated graphic input model, (ii) to simulate the relationship of external shading devices and shadows based on sun path, the orientation of building, (iii) to visualize the shadow casting by shading devices, and (iv) to provide designers with possible solutions to create energy-efficient external shading device for a specific building.

title Maximising the Benefits of CAD Systems in Architectural Education

summary The positive impact of Computer Aided Design (CAD) in professional architectural practice has been in focus in recent times but relatively little has been written on its significance in the education of the contemporary architect. It is common knowledge that the profession of architecture is currently undergoing enormous strains as it battles to keep abreast of trends and developments in a period of series of rapid advancement in science, technology and management (RIBA, 1992). Whilst attempts are being made to redress the shortcomings of the profession in the above context, the requirements for architectural education are yet to forge a coherent strategy for the implementation of CAD/IT in the curriculum of schools of architecture. In almost every other field, including engineering, medicine and the humanities, computing application to problem-solving and decision-making is seen as a way forward as we move into 21st century. Architectural education must integrate CAD/IT into the teaching of core modules that give the architect distinctive competence: studio design. That is one of the best ways of doing justice to the education of the architect of today and the future. Some approaches to the teaching of CAD in schools of architecture have been touched upon in the recent past. Building upon this background as well as an understanding of the nature of design teaching/learning, this paper examines ways of maximising the benefits of CAD systems in architectural education and of bringing computer aided designing into the studio not only to enhance design thinking and creativity but also to support interactive processes. In order to maximise or optimise any function, one approach is to use the hard systems methodology which utilises analytic, analogic and iconic models to show the effect of those factors which are significant for the purposes being considered. The other approach is to use the soft systems methodology in which the analysis encompasses the concept of a human activity system as a means of improving a situation. The use of soft systems methodology is considered more appropriate for dealing with the problem of design which is characterised by a flux of interacting events and ideas that unroll through time. The paper concludes that the main impediment to maximising the benefits of CAD systems in architectural education is not only the inappropriate definition of the objectives for the implementation of CAD education but also that the control subsystems are usually ill-structured and relatively poorly defined. Schools must attempt to define a coherent and consistent policy on the use of CAD systems as an integral part of studio design and evolve an in-house strategic and operational controls that enable the set objectives to be met. Furthermore, it is necessary to support the high level of productivity from CAD systems with a more efficient management system, especially in dealing with communication, data sharing via relational database, co-ordination and integration. Finally, the use of soft systems methodology is recommended as the way forward to optimising CAD systems in design education as it would provide continuous improvements while maintaining their productive value.

title The Management of Knowledge in Architectural Companies by Reconstruction of Problem Solving Systems
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The purpose of this paper is to present a theory for 'knowledge management' in architectural firms. This theory is based upon the premise that knowledge as well as employees (..the designer as a knowledge worker..) are regarded as means of production and that for both of these resources economic values exist during a limited period of time. Similar to the management efforts to optimize the use of labour and 'material' equipment the use of knowledge should be optimized by adequate management. The presented theory for the management of knowledge introduces a new profession in the organization of an architectural firm: the knowledge manager. And within this context a knowledge base is regarded as a tool to help to perform one of the tasks of this professional. The central part of this theory consists of a cognitive reconstruction of problem solving systems. This reconstruction provides a layout for a knowledge base as well as a 'road map' to guide the discussions on 'what knowledge is used', 'who learned what' and 'to whom must experience be transferred'. Employees as the most 'cognitive actors' in problem-solving in design processes can be traced. The management can decide on wether to emphasise the concentration of knowledge by these persons or to emphasize the transfer of their knowledge to others. The use and meaning of knowledge bases for each of these management approaches are completely different.

title Case-based Reasoning in Building Design: Problems of Case Elicitation and Retrieval
source The Int. Journal of Construction IT 2(4), pp. 49-62
summary This article deals with a set of problems that arose in the course of the FABEL project in order to build a system assisting in the design of complex buildings: Task analysis indicated a case-based approach with the subtasks of retrieval, assessment and adaptation of layouts. The idea of first choosing a retrieval method which would then guide the further knowledge elicitation process did not work, because there was no single suitable method. We investigated retrieval methods based on keywords, on vectors, bitmaps, gestalten and on topological structures. As it turned out, each method imposes a particular interpretation on a layout and serves different retrieval purposes. Using multiple methods required an open software architecture providing case management facilities for the various methods. Last not least, the extraction of relevant cases from integrated building models is not trivial at all. Both automatic routines of standard cases and manual extraction of special cases should be available.

title Visual and Spatial Analysis in Office Design
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The demands for rapid response to complex problems, flexibility, and other characteristics of today's workplace, such as a highly trained work force, have led many organizations to move from strict hierarchical structures to a more flexible project team organization. The organizational structure is broader and flatter, with greater independence given to organizational units, in this case the project teams. To understand the relationship between project team communication patterns and the design and layout of team space, a study was conducted of an architectural office before and after a move to new space. The study involved three project teams. Information was collected on individual communication patterns; perceptions of the ease of communication; and the effectiveness of the design and layout of physical space to support these communications. In order to provide guidance for critical decision-making in design, these communication data were correlated with a series of measures for the specification of team space enclosure and layout. These group/team space measures were adaptations of existing measures of individual work space, and included an enclosure measure, based on an enclosure measure developed by Stokols (1990); a measure of visual field, based on the "isovist" fields of Benedikt (1979); and an "integration" measure, based on the work of Hillier and Hanson (1984). Results indicate both linear and non-linear relationships between interaction patterns and physical space measures. This work is the initial stage of a research program to define a set of specific physical measures to guide the design of supportive work space for project teams and work groups within various types of organizations.

title CAFE: Composition for Architects - Forms and Emotions
doi https://doi.org/10.52842/conf.ecaade.1994.x.l3s
source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, pp. 249
summary In the architectural creation process there has always been an inclination to improve the methods of designing in the way of ,,objectivization" of designing process. Objectivization which would explain why we do design in this way and not the other. In spite of the trend to the total objectivization (Vitruvius, Alberti, Palladio), the results appeared to be still subjective, i.e. they included methods of designing typical of the one and only architect. This fact made them completely useless in the designing practice. On the other hand one cannot underestimate their meaning as to this very practice. Because it is just thanks to them that the development of designing studies has taken place. We do learn not only watching works of great architects, but also studying their opinions concerning problems of form, function and construction. That is why it seems to be useful to collect experiences concerning the classic theory of architectural composition, which have been gathered through centuries, as well as to try once again to objectivize the process. Composition information arranged in the form of data-base would create the ground for proper functioning of an expert system uniting diagnostic and planning functions. Study of that kind, not claiming design applications could be an excellent educational equipment in teaching architectural composition. In the proposed teaching system attempts have been made to look at the architectural composition theory in the light of the perception of the form, and - emerging in this process - emotional and aesthetic evaluations. In order to define which evaluations have been most often expressed during the perception process of architectural forms, the students of Architecture Faculty in Bialystok Technical University have been polled on the subject: ,,Which words are most commonly used in the descriptions of architecture works?"

title A Taxonomy of Architecture: Core of a Theory of Design
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The authors developed a taxonomy of concepts in architectural design. It was accepted by the Advisory Committee for education in the field of architecture, a committee advising the European Commission and Member States, as a reference for their task to harmonize architectural education in Europe. The taxonomy is based on Domain theory, a theory developed by the authors, based on General Systems Theory and the notion of structure according to French Structuralism, takes a participatory viewpoint for the integration of knowledge and interests by parties in the architectural design process. The paper discusses recent developments of the taxonomy, firstly as a result of a confrontation with similar endeavours to structure the field of architectural design, secondly as a result of applications of education and architectural design practice, and thirdly as a result of theapplication of some views derived from the philosophical work from Charles Benjamin Peirce. Developments concern the structural form of the taxonomy comprising basic concepts and levelbound scale concepts, and the specification of the content of the fields which these concepts represent. The confrontation with similar endeavours concerns mainly the work of an ARCUK workingparty, chaired by Tom Marcus, based on the European Directive from 1985. The application concerns experiences with a taxonomy-based enquiry in order to represent the profile of educational programmes of schools and faculties of architecture in Europe in qualitative and quantitative terms. This enquiry was carried out in order to achieve a basis for comparison and judgement, and a basis for future guidelines including quantitative aspects. Views of Peirce, more specifically his views on triarchy as a way of ordering and structuring processes of thinking,provide keys for a re-definition of concepts as building stones of the taxonomy in terms of the form-function-process-triad, which strengthens the coherence of the taxonomy, allowing for a more regular representation in the form of a hierarchical ordered matrix.

title An Open Daylighting Simulation Environment
source Carnegie Mellon University, Pittsburgh
summary Various studies have shown that performance simulation tools have not been integrated effec- tively in the architectural design process. The conventional lighting simulation tools have been characterized as decision verification tools rather than design support tools. Particularly in the early design stage, when crucial and often irreversible decisions are made, this evident lack of appropriate lighting simulation environments represents a serious drawback. The "mono-directionality" of the conventional simulation tools can be identified as one of the factors responsi- ble for insufficient integration of computational lighting modeling tools in the design process. In response to this circumstance, this thesis presents the conceptual background and the proto- , typical realization of an "open" daylighting simulation environment (GESTALT) to support architectural lighting design and education. Open simulation environments aim at extension (and inversion) of the design-to-performance mapping mechanisms of the conventional build- ing performance simulation tools. Toward this end, two fully operational versions of GESTALT have been implemented. GESTALT-01 is an explicit implementation based on invertible "fast-response" computational modules. GESTALT-02 is an implicit version that uses a comprehensive computational daylight simulator and investigative projection technique for performance-driven design exploration. Concepts, implementations, case studies, contributions and future directions are presented.

title Innovative Expert Systems With Hypertextual User Interfaces: A Special Support for the Building Recovering Project
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In this paper, first of all a short account on the peculiarity of knowledge in the domain of Architectural and Building Project, particularly in the Building Recovering Project is given. Thatmeans to focus the concept of "degree of authority" of different types of knowledge with regard to project: regulations; specialist literature having in practice the value of self-regulation; technical updating; exemplary design cases; warnings; analysis methods; heuristics; orientating references. Consequently, the different roles of two basic design & decision support systems, that is expert systems and hypertexts, are considered. The former seem to be quite fit for representing information and knowledge linked to a clear "authority", the one of experts in a certain domain; the latter seem to be quite fit for illustrating the interdisciplinary complexity, different historicinterpretations, various analogous references, and so on. Afterwards, the limits of expert systems based on the logic "true-false" are underlined, and the perspective of expert systems based on more sophisticated and appropriate rules and metarules is proposed. At last, the possible structure of such an innovative expert system, with a hypertextual interface, in the domain of Building Recovering Project is exemplified.

title Knowledge Acquisition by Measurement: The Domain of Building Change
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper presents a study that is aimed at finding a basis for systematic knowledge acquisition. More specifically, it attempts to introduce, knowledge acquisition by measurement: a method thatallows objective evaluation of empirical observations. Measurement has proven to be a significant tool to acquire, evaluate, and upgrade knowledge in some knowledge domains. In other domains,such as the domain of building change, measurement is barely subject of study. Building change knowledge acquisition by measurement seems to become a significant subject of study for several reasons: (i) increase our objective knowledge of previous building changes, (ii) allow systematic monitoring of present changes, and (iii) assist decisions planning for change in new buildings. In current studies, questions such as what were required changes, what were the building elements that fulfilled a change, how often did a building change, and what were the costs related to a change, often get no systematic or objective answers. Hence, to overcome that, I am concerned with finding a method that is to answer the following questions: 1) What is the domain of building change; 2) Is a method of knowledge acquisition by measurement adequate to represent buildingchanges; 3) Can empirical observations of building change be systematically represented and objectively evaluated using this method; and 4) How can this method be applied to assist theunderstanding of previous changes, the control of present changes, and assist planning for building change. The method introduced is based on three modules: (i) domain of building change; (ii) modelling this domain; and (iii) measurement. These three modules enable the formulation of the measurement of building change, namely the change indicator. Multiple change indicators, such as cost change indicator, or occurrence change indicator can measure empirical observations ofbuilding change. Sequential steps that lead to the development of this method start by section 1, where the domain of building change is specified. In section 2 this domain is modelled, and in section 3, knowledge acquisition by measurement method is introduced. A case study, shows how empirical building changes can be measured is explained in section 4. In section 5, three possible applications are introduced, and in section 6, I explain how a computerized prototype would enhance the efficiency of using such applications. Findings and conclusions resulting from this study are summarized in section 7.

title Matchmaker: An Instrument for Matching Demand for and Supply of Buildings and Revealing Specific Discrepancies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary To match supply and demand of buildings, various approaches are possible. While artificial intelligenceis favoured by some, we think that a less 'heavy' approach can be more cost and time efficient. The casewe have chosen to exemplify our approach concerns architectural heritage. To match supply and demandwhile at the same time respecting the constraints imposed by cultural heritage, it is necessary to bringthem together and to effectuate feasibility studies in the shortest possible time. The feasibility study shouldbe served by tools allowing the various partners to communicate on the level of the match between them, translated in terms of spatial organisation and building constraints. In the past years, our designmorphology group has developed and tested a graphic-based reordering tool which has been applied to large governmental buildings, both existing and new. The same tool can be used for weighted objectives ranking and evaluation, to have a synthetic view of the combined basic preferences and differences of the involved parties as for example in a jury wise evaluation and ranking of alternative proposals. The proposed tool is the electronic and graphic version of the data and association matrices, which have been for a long time recommended for use in the preliminary phases of design. But as long as these instruments could only be drawn and redrawn on paper they were much too ineffectual and found little real application. The developed tool is connected by sub-routines to a computer aided design package, within which the spatial patterns are translated into plans and attached data bases. The matching takes place in a number of steps. The first is to describe the organisation (the demanding party) as functional units which can be made corresponding with spatial units. The prescription of spatial needs can take place in both quantitative and qualitative manners. The Matchmaker tools offer the possibility of interactive clustering of spatial needs. Another step, which can be taken concurrently, is to describe the monument in spatial units and distance relationships. The input can be generated directly within the matrix, but it is much easier, more self evident and realistic to generate this automatically from the draughted plan. The following step is the input of constraints originating from heritage preservation objectives, expressed in levels of authorised intervention. Again, the Matchmaker tools offer here the possibility of visual clustering of spatial units, their relationships and associated properties. In the next step, the matching takes place. In this step the actual positions, properties and constraints of existing spaces in the monument are compared (and visualised by discrepancies views) to the optimised and clustered spatial needs of the end user. In the following phase, the feasibility in terms of space, building fabric and costs can be appraised. Once a compromise has been attained, preliminary proposals can be designed and laid down in terms of drawings. The spatialdesigns can then again be translated into matrix views and evaluated.

title Sketch-Trigger: A Specification for a Form Generator and Design Analysis Toolbox for Architectural Sketching
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In order to develop design and decision support techniques in the early sketch design phases, weshould (1) experience and (2) observe real behaviour in practice, (3) transform observations intoideas for improvement, (4) develop behaviour models to explain the sketch design activities and(5) to evaluate between the proposals, (6) decide between the alternatives, (7) implement theselected option in a supporting tool. Our paper reports about the results of step 3 in particular inthe first phase of a Ph D project, started this year. Our main objective is to amplify the effects ofthe sketch as a very effective instrument to generate original forms and to stimulate the mind to discover new shapes and meanings in the roughly sketched patterns. Instead of considering the sketch only as a representation of what the designer has in mind as is usually assumed in CAD systems, we see sketching as form activation. Thus, we want also to offer triggering images to spark off the imagination of the designer while generating images which are practically impossibleto create by hand and certainly not at short notice. The main improvement proposed is the use of an evolutionary form breeding system: one or more sketched parent images (either ready-made'partis' or basic schemes drafted by the designer) presented in the centre of the screen, will generate surrounding mutated children as defined at random but constrained by default or customization of the available transformations. By selecting one or more children a next generation will be produced in the same way. At all times the designer can introduce or reduce constraints. To complete the usually offered 'classical' symmetrical, spatial and logical operations,we want to introduce dis-functional operations like dislocation, explosion, deformation, anti-logic etc, in short all kinds of antagonistic operations, among them the transformations applied indeconstructionist and post-modern design. Our expectation is that these operations will correspond roughly to the 'move' pertaining to a design entity as the operational unit most appropriate for design behaviour research, in particular the analysis of the chunking and parsing behaviour of the designer. The applicability of the 'move' approach has been shown experimentally by Habraken and others. Goldschmidt has abandoned the usual typology approach of protocolanalysis based on moves and concentrated on the linking of moves, but has been hampered by the lack of a good representational instrument. This brings us to the representation of moves and linkages as a research instrument. The 'linkograph' approach as proposed by Goldschmidt is a first step towards a graphical representation of the designers associative reasoning mode, necessary for tracking the heuristics of designers at the most basic level, but its practical implementation remained as yet incredibly laborious. What is proposed here is an instrument and approach which makes such registration and analysis possible within a structured software environment.

title Integration System for Urban Design from Planning Management to Visalization
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Advanced tools based on CAD or GIS systems and simulation methods have recently been introduced to support the many aspects of urban planning (design, analysis, evaluation, presentation). This research aims at constructing a system by integrating these support tools and linking GIS and simulation tools. The major purpose of this system are to manage the geographical data base of the target urban area, utilize the digital information of the area for planning and analysis,evaluate the impact of alternative proposals on the physical environment such as sunlight and daylight, visualize the results of analysis, and support the management of urban redevelopment /development projects. This paper shows some applications to illustrate usefulness of the system. These examples are concerned with a contemporary problem in urban planning of Tokyo: redevelopment of low-rise high-density residential districts and high-rise development in the central business districts. Urban redevelopment for the high-density urban areas in Japan requiresa evaluation of alternative plans by visualizing their environmental impact. This system enables the quantitative analysis of the environmental impact by using 3-dimensional geographical data andsimulation methods. In general, the merit and effect of planning support systems are recognized in terms of the "efficiency" of the planning process. The primary function of GIS is thought to bethe unification and management of various pieces of information. In addition, this research indicates the effectiveness of the integrated system in terms of utilizing the geographical information and visualizing the image of the future environment.

title TEAnO or the computer assisted generation of manufactured aesthetic goods seen as a constrained flux of technological unconsciousness
source International Conference on Generative Art
summary TEAnO (Telematica, Elettronica, Analisi nell'Opificio) was born in Florence, in 1991, at the age of 8, being the direct consequence of years of attempts by a group of computer science professionals to use the digital computers technology to find a sustainable match among creation, generation (or re-creation) and recreation, the three basic keywords underlying the concept of “Littérature potentielle” deployed by Oulipo in France and Oplepo in Italy (see “La Littérature potentielle (Créations Re-créations Récréations) published in France by Gallimard in 1973). During the last decade, TEAnO has been involving in the generation of “artistic goods” in aesthetic domains such as literature, music, theatre and painting. In all those artefacts in the computer plays a twofold role: it is often a tool to generate the good (e.g. an editor to compose palindrome sonnets of to generate antonymic music) and, sometimes it is the medium that makes the fruition of the good possible (e.g. the generator of passages of definition literature). In that sense such artefacts can actually be considered as “manufactured” goods. A great part of such creation and re-creation work has been based upon a rather small number of generation constraints borrowed from Oulipo, deeply stressed by the use of the digital computer massive combinatory power: S+n, edge extraction, phonetic manipulation, re-writing of well known masterpieces, random generation of plots, etc. Regardless this apparently simple underlying generation mechanisms, the systematic use of computer based tools, as weel the analysis of the produced results, has been the way to highlight two findings which can significantly affect the practice of computer based generation of aesthetic goods: ? the deep structure of an aesthetic work persists even through the more “desctructive” manipulations, (such as the antonymic transformation of the melody and lyrics of a music work) and become evident as a sort of profound, earliest and distinctive constraint; ? the intensive flux of computer generated “raw” material seems to confirm and to bring to our attention the existence of what Walter Benjamin indicated as the different way in which the nature talk to a camera and to our eye, and Franco Vaccari called “technological unconsciousness”.

title SEED: A Software Environment to Support the Early Phases in Building Design
source Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title Digital Design In Architecture: First Light, Then Motion, and Now Sound

summary If we restricted our idea of architecture to only the traditional and static description of visual space and form, we might not be considering significant characteristics of the places we are designing. If, however, we accepted even a limited definition, as stated by Le Corbusier, that "architecture is the masterly, correct, and magnificent play of masses brought together in light", we would at least be forced to consider the dimension of time as the ever-changing daylight modifies the way our creations are perceived. However, neither the built nor the natural environments are silent. Sound affects the way we feel about certain events and places, and in turn, places we create can modify or influence the way we hear sounds. As computers become more audio capable, we can expect changes in the ways that architects plan, design, and present their projects. Issues of both objective and nonobjective sound can become significant factors throughout the building delivery process. As the visual sophistication and acoustic expectations of society rise because of the ubiquitous power of electronic multimedia - as well as "cross-media" applications (film, video, television, and scientific visualization) it is inevitable that the architectural design and presentation processes reflect these changes.

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.
