summary The educative proposal was based on the summary attained through experiences piled up during the 2 last semester courses, 2/2006-1/2007. This proposal corresponds to a mix of methodology (by personal attendance / by internet). Founding on the Theory of the Game (Eric Berne 1960) and on different theories such as: Multiple intelligences (Haward Gardner 1983), Emotional Intelligence (Peter Salowey and John Mayer 1990, Goleman 1998), Social Intelligence (Goleman 2006), the Triarchy of Intelligence (Stemberg, R.J. 1985, 1997), “the hand of the human power”, it´s established that the power of the voice, that of the imagination, the reward, the commitment and association produce a significant increase of the productivity (Rosabeth Moss Kanter 2000), aside from the constructive processes of the knowledge (new pedagogical concepts constructivista of Ormrod J.E. 2003 and Tim O´Reilly 2004).

source Hypertext : Concepts, System and Applications, Proceedings of the European Conference on Hypertext, ECHT'90. Cambridge University Press., 1990. pp. 152-165 : ill. includes bibliography
summary PHIDIAS is a hypermedia system for supporting environmental design. It embodies a theory of design as continual alternation between two complementary activities: construction of solution form and argumentation about construction. To support these activities it implements a number of advanced hypermedia concepts. These include an applicative query language providing search by both structure and content, virtual structures, composite graphic notes, query-based graphic clustering, and 'triggered' queries which connect construction acts to relevant sections of the argumentive network. PHIDIAS constitutes a new type of integrated information environment design

summary Phidias is software which integrates computer-aided design graphics with hypermedia to create a hypermedia CAD - or hyperCAD - system. Phidias allows architects to develop building form while having immediate and nearly effortless access to a rich store of textual, numerical, and graphical information. This information access can make a wide variety of design literature and research findings available to architects in a way and at a time that they can easily use it. Thus, Phidias is intended to help bridge the gap between architectural research and practice.

summary Traditional computer drafting systems and three- dimensional geometric modeling systems work in bottom-up fashion. They provide a range of graphic primitives, such as vectors, arcs, and splines, together with operators for inserting, deleting, combining, and transforming instances of these. Thus they are conceptually very similar to word processors, with the difference that they operate on two- dimensional or three-dimensional patterns of graphic primitives rather than one-dimensional strings of characters. This sort of system is effective for input and editing of drawings or models that represent existing designs, but provides little more help than a pencil when you want to construct from scratch a drawing of some complex object such as a human figure, an automobile, or a classical column: you must depend on your own knowledge of what the pieces are and how to shape them and put them together. If you already know how to draw something then a computer drafting system will help you to do so efficiently, but if you do not know how to begin, or how to develop and refine the drawing, then the efficiency that you gain is of little practical consequence. And accelerated performance, flashier color graphics, or futuristic three-dimensional modes of interaction will not help with this problem at all. By contrast, experienced expert graphic artists and designers usually work in top-down fashion-beginning with a very schematic sketch of the whole object, then refining this, in step-by-step fashion, till the requisite level of precision and completeness is reached. For example, a figure drawing might begin as a "stick figure" schema showing lengths and angles of limbs, then be developed to show the general blocking of masses, and finally be resolved down to the finest details of contour and surface. Similarly, an architectural drawing might begin as a parti showing just a skeleton of construction lines, then be developed into a single-line floor plan, then a plan showing accurate wall thicknesses and openings, and finally a fully developed and detailed drawing.

title Discoursing on Urban History Through Structured Typologies
doi https://doi.org/10.52842/conf.acadia.1992.157
source Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 157-175
summary How can urban history be studied with the aid of three-dimensional computer modeling? One way is to model known cities at various times in history, using historical records as sources of data. While such studies greatly enhance the understanding of the form and structure of specific cities at specific points in time, it is questionable whether such studies actually provide a true understanding of history. It can be argued that they do not because such studies only show a record of one of many possible courses of action at various moments in time. To gain a true understanding of urban history one has to place oneself back in historical time to consider all of the possible courses of action which were open in the light of the then current situation of the city, to act upon a possible course of action and to view the consequences in the physical form of the city. Only such an understanding of urban history can transcend the memory of the actual and hence the behavior of the possible. Moreover, only such an understanding can overcome the limitations of historical relativism, which contends that historical fact is of value only in historical context, with the realization, due to Benedetto Croce and echoed by Rudolf Bultmann, that the horizon of "'deeper understanding" lies in "'the actuality of decision"' (Seebohm and van Pelt 1990).

One cannot conduct such studies on real cities except, perhaps, as a point of departure at some specific point in time to provide an initial layout for a city knowing that future forms derived by the studies will diverge from that recorded in history. An entirely imaginary city is therefore chosen. Although the components of this city at the level of individual buildings are taken from known cities in history, this choice does not preclude alternative forms of the city. To some degree, building types are invariants and, as argued in the Appendix, so are the urban typologies into which they may be grouped. In this imaginary city students of urban history play the role of citizens or groups of citizens. As they defend their interests and make concessions, while interacting with each other in their respective roles, they determine the nature of the city as it evolves through the major periods of Western urban history in the form of threedimensional computer models.

My colleague R.J. van Pelt and I presented this approach to the study of urban history previously at ACADIA (Seebohm and van Pelt 1990). Yet we did not pay sufficient attention to the manner in which such urban models should be structured and how the efforts of the participants should be coordinated. In the following sections I therefore review what the requirements are for three-dimensional modeling to support studies in urban history as outlined both from the viewpoint of file structure of the models and other viewpoints which have bearing on this structure. Three alternative software schemes of progressively increasing complexity are then discussed with regard to their ability to satisfy these requirements. This comparative study of software alternatives and their corresponding file structures justifies the present choice of structure in relation to the simpler and better known generic alternatives which do not have the necessary flexibility for structuring the urban model. Such flexibility means, of course, that in the first instance the modeling software is more timeconsuming to learn than a simple point and click package in accord with the now established axiom that ease of learning software tools is inversely related to the functional power of the tools. (Smith 1987).

title Bezier Surface : Surface Intersection
source IEEE Computer Graphics and Applications. January, 1990. vol. 10: pp. 50-58
summary In this article the authors explain the computational requirement and accuracy of two methods for finding the intersection of Bezier surfaces. In both methods, the existence of an intersection curve is confirmed by using the convex hull property of such surfaces. The first method evaluates the intersection by recursive subdivision of two patches with overlapping hulls. The second method detects a point on the intersection curve, then incrementally traces the intersection in the parametric spaces of the two surfaces. With both methods the intersection of a pair of first-order planar patches must be solved analytically. The intersection is approximated by first-order Bezier patches in the first case, and by planar triangles in the second. Overall, the method of incremental tracing gives more accurate results than the method of recursive subdivision

title A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

source The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 347-361
summary In the conventional way of teaching architecture, it is common to think of design as the final synthesis of an intellectual process (composizione in Italian) integrating different elements from different curriculum subjects: history, structural analysis., technology, regional and urban planning, and so on. These elements, being comprehensive of their specific domains, together build the project. This process is supported by a long traditional that cannot easily be modified; however, we must not consider it to be the only one. Architectural practice should be much more. The Scuole di Architettura has walked a long and difficult road in the last thirty years., with a significant widening of interest in social, political, and economic issues. There have been recurring attempts at epistemological reformulation in some areas. There has been an acknowledgment of a crisis in contemporary town planning and a dimming of several certitudes that had developed with the birth and growth of the modernist school. And there has been a weakening of the promises that had given life to the vigorous discussion about town and regional planning. All of this leads to a reconsideration of the meaning and the deeper assumptions that the project implies, a question mark at the center of the human sciences that architectural practice involves. The old tradition., which assigned composition a central role in the project, is no longer sufficient because it is related to a reductive reading of epistemology that views human sciences as defining segments of physical knowledge of the actual world. Contemporary reflection on the difference between understanding and unfolding, together with the attention given to interpreting a moment as compared to purely describing one, gives to the project the task of inquiry instead of solution.

title Knowledge Based Design Systems
source 576 p. : ill Reading, Mass.: Addison-Wesley, 1990. includes bibliographies and index.
summary This book describes the bases, approaches, techniques, and implementations of knowledge-based design systems, and advocates and develops new directions in design systems generally. A formal model of design coupled with the notion of prototypes provides a coherent framework for all that follows and is a platform on which a comprehension of knowledge-based design rests. The book is divided into three parts. Part I, Design, examines and describes design and design processes, providing the context for the remainder of the book. Part II, Representation and Reasoning, explores the kinds of knowledge involved in design and the tools and techniques available for representing and controlling this knowledge. It examines the attributes of design that must be described and the ways in which knowledge-based methods are capable of describing and controlling them. Part III, Knowledge-Based Design, presents in detail the fundamentals of the interpretation of design, including the role of expert systems in interpreting existing designs, before describing how to produce designs within a knowledge-based environment. This part includes a detailed examination of design processes from the perspective of how to control these processes. Within each of these processes, the place and role of knowledge is presented and examples of knowledge-based design systems given. Finally, the authors examine central areas of human design and demonstrate what current knowledge-based design systems are capable of doing now and in the future

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).

summary The city of Vienna follows a long-term initiative to become a Smart City. Within 2050 it aims to reduce 80% of the CO2 emissions (in comparison to 1990) and looks forward to generate ways for a sustainable energy production. (Smart City Framework Strategy 2014) Reaching this targets requires a complex planning process which involves interdisciplinary stakeholders and decision makers. An interactive multi-dimensional environment, comprising spatial objects and data models, is a helpful tool during these planning processes. This paper proposes a suitable path for the development of a structural framework for such an environment. The benefits of such an environment are shown in detail, based on an application of the economic solar heat potential in Vienna.

source Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 426-439
summary In the 1950’s, the Levitts put mass-production and the reverse assembly line into use in the building of thousands of single-family houses. However, the lack of variation that made their construction process so successful ultimately produced a mundane suburban landscape of sameness. While there were many attempts to differentiate these Levitt Cape Cods, none matched the ingenuity of their original construction process. The notion of mass-customization has been heavily theorized since the 1990’s, first appearing in the field of management and ultimately finding its way into the field of architecture. Greg Lynn used mass-customization in his design for the Embryological House in which thousands of unique houses could be generated using biological rules of differentiation (Lynn 1999). Other industries have embraced the premise that computer-numerically-controlled technologies allow for the production of variation, though it has not been thoroughly studied in architecture. While digital fabrication has been integral in the realization of several high-profile projects, the notion of large-scale mass-customization in the spec-housing market has yet to become a reality. Through the execution of an addition to a Cape Cod-style house, we examine the intersection between prefabricated standardized panels and digital fabrication to produce a mass-customized approach to housing design. Through illustrations and a detailed description of our design process, we will show how digital fabrication technologies allow for customization of mass produced products.

summary In this paper, the nature of distinction drawing, in the sense of George Spencer Brown, is examined with special reference to the distinction between the self and the other. It is noted that a distinction, which must draw its self, also requires an other and a transfer distinction, both within a particular distinction and for that distinction to be part of, and that these can generate the purpose of the distinction as becoming, of, by and for itself.

We have moved from being developers of ideas and technology on the inside of the development loop to being consumers of products developed in the commercial market place, outside the loop. Certain negative consequences are discussed. Finally, some suggestions are made for turning ourselves "right side out" again.

summary Transferring innovative university-based research results to the industry or practice that will ultimately use them is an arduous, time-consuming effort. One way to effect this technology transfer is to develop a demonstrable prototype product and then find or form a corporation that can expand the prototype into a full product and market it to the profession. Another way, which can shorten the transfer process, is to "sell" the idea, rather than the product, to a corporation that has the vision, the resources and the technical competency to support its development, with the intent to eventually market it. In this paper, we describe a case study of this latter approach, based on our seven year experience of researching, developing and transferring innovative architectural CAD technology. We describe the birth, growth, and maturity of Worldview, a computer-aided design and modeling system for use by architects. The project was initiated in 1983, and went through five software versions, numerous grants and grant extensions, two granting corporations, and extensive field testing. The software has developed into a mature system, with sufficient functionality appropriate for commercial distribution. The paper describes not only the factual chronology of the project, but also highlights the advantages and drawbacks of market-oriented university research. We conclude with suggestions as to how the process may be improved, and how problems and obstacles can be minimized.

title Process and Knowledge in Design Computation
source Journal of Architectural Education. February, 1990. includes bibliography
summary The challenge of understanding the many facets of design has been a central issue in attempting to computationally define design processes and knowledge. The historical progression of computers in design has been characterized by high aspirations repeatedly humbled by the complexity of design problems. Fundamental questions concerning the role and impact of computers in design should be re-examined in light of new developments in Computer-Aided Design (CAD) and Artificial Intelligence (AI), and the progressive understanding of design itself. At the heart of these issues must lie a mutual understanding of the respective traits of design and computation, and the balance of interaction between them. In this paper two avenues, expressed in terms of mappings between design and computation, are explored with the intention of clarifying the relationship between the theories of design and computation. First, the relationship between models of the design process and computational search strategies is explored. Several paradigms (problem solving, puzzle making, and constraint satisfying), which demonstrate a breadth of approaches to modeling design, are presented along with their computational implications. Second, relationships between design knowledge and computational representation schemes are discussed. Emphasis is placed on drawing from cognitive and computational knowledge representation schemes to represent design knowledge. Finally, some thoughts on integrating these design models and knowledge representation schemes into computer systems to assist designers are discussed

source The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 247-259
summary We have developed a computer-based design aid called Janus, which is based on a model of computer-supported design that we think has significance for the future of architectural education. Janus utilizes a knowledge-based approach to link a graphic construction system to hypertext. This allows the computer to make useful comments on the solutions that students construct in a CAD-like environment. These comments contain information intended to make students think more carefully about what they are doing while they are doing it. In other words, Janus promotes what Donald Schon has called "reflection-inaction" (Schon, 1983). The Janus design environment is named for the Roman god with a pair of faces looking in opposite directions. In our case the faces correspond to complementary design activities we call construction and argumentation. Construction is the activity of graphically creating the form of the solution e.g., a building. Traditionally this has been done with tracing paper, pencils, and pens. Argumentation is the activity of reasoning about the problem and its solution. This includes such things as considering what to do next, what alternative courses of action are available, and which course of action to choose. Argumentation is mostly verbal but partly graphical.
