summary Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title APPLICATION OF FULL-SCALE MODELLING IN VIETNAM: AN OUTLINE FOR DISCUSSION
source Beyond Tools for Architecture [Proceedings of the 5th European Full-scale Modeling Association Conference / ISBN 90-6754-375-6] Wageningen (The Netherlands) 6-9 September 1994, pp. 59-70
summary This paper discusses the possibility of applying full-scale modelling in Vietnam, a non-western so called developing country. It deals with two main questions: 1) Is the application of full-scale modelling to be restricted to the West only? 2) what are the possibilities, constraints and fields of application - with attention to the methodological validity and technical solution for full-scale modelling in Vietnam? It is argued that since full-scale modelling is based on people-environment interaction, it should, in principle, apply to studies about people–environment relation anywhere on earth. On the methodological validity, it is discussed that application of full-scale modelling in Vietnam faces similar methodological problems as encountered in European applications (such as people's behaviour in experiment, ability to understand the abstraction of models, etc.) although at another level as this paper will make clear. However, it would be needed to design a modelling kit that is of low costs and adapted to the availability of local materials and suitable for the climatic condition of Vietnam. Two fields of application are projected as most applicable in Vietnam: modelling in architectural education and research investigation. Application for user's participation in the design process will depend on the development of building policy in the country.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

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 A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

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.

summary This paper will present a project, which was first initiated in 1994 as a graduate students seminar and is now being continued as a research project in a cooperation of computer scientists, architects and archaeologists. An ancient roman city (Colonia Ulpia Traiana near todays Xanten in Germany) has been reconstructed, using various levels of abstraction. On the coarsest level, a 3D-model of the whole city was established, distinguishing between different historical periods of the city. The second level picks places of special interest (temples, the forum, the amphitheater, the townbaths etc.) and reconstructs these buildings or groups of buildings. On the finest level important interior parts or functional details like the Hypocaustae in the town-baths are modelled. All reconstructions are oriented as close as possible to results from excavations or other available documents. All levels of the 3D-model have been visualized using photorealistic images and sequences of video animations. The 3D model is integrated into a multimedia environment, augmenting the visualization elements with plans of the city and individual buildings and with text documents. It is intended, that parts of the outlined system will be available at the site of the ancient city, where today a large public archaeological park is located.

summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

summary The concept of ODE (Open Design Environment) and corresponding system were presented in 1991. Then the new concept of NODE. which is networked version of ODE. was generated to make wide area collaboration in 1994. The aim of our research is to facilitate the collaboration among the various people involved in the design process of an urban or architectural project. This includes various designers and engineers, the client and the citizens who may be affected by such a project. With the new technologies of hyper medium, network, and component architecture, we have developed NODE system and applied in practical use of the collaboration among the various people. This study emphasizes the interactive 3-D design tool of NODE which is able to make realistic and realtime presentation with interactive interface. In recent years, ProjectFolder of NODE system, which is a case including documents, plans, and tools to proceed project., is created in the World Wide Web (WWW) and makes hyper links between a 3-D object and a text, an image. and other digital data.

summary Fractal geometry provides a powerful tool to explore the world of non-integer dimensions. Very short programs, easily comprehensible, can generate an extensive range of shapes and colors that can help us to understand the world we are living. This shapes are specially interesting in the simulation of plants, mountains, clouds and any kind of landscape, from deserts to rain-forests. The environment design, aleatory or conditioned, is one of the most important contributions of fractal geometry to CAAD. On a small scale, the design of fractal textures makes possible the simulation, in a very concise way, of wood, vegetation, water, minerals and a long list of materials very useful in photorealistic modeling.

title An Outline of the Requirements for a Computer Supported Collaborative Design System
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Computer-Aided Architectural Design (CAAD) systems have adequately satisfied several needs so far. They have dramatically improved the accuracy and consistency of working drawings, enabled designers to visualize their design ideas in three-dimensions, allowed the analysis of designs through data exchange and integrated databases, and even allowed the designers to evaluate (and in some cases generate) designs based on comparisons to previous cases and/or the formalization of specific rules and grammars. Yet, there is a general consensus that CAAD systems have not yet achieved their full potential. First, most systems employ a single-user approach to solving architectural problems which fails to grapple with the fact that most design work is done through teamwork. Second, current systems still cannot support early design stages which involve client briefing, data collection, building program formulation, and schematic design generation. Thus, if CAAD is to ultimately benefit the design process, it must (1) emulate and support the design team approach to architectural problem solving and (2) be deployed in the earliest possible stages of the design process. This paper seeks to study remedies to both of the afore-mentioned limitations through focusing on the interaction between a set of requirements (the building program) and the architectural solution that satisfies them (the schematic design). The core of this interaction forms the fundamental dialectic and collaborative nature of what is called designing: a concerned social activity that proceeds by creating architectural elements to address a set of requirements and their re-thinking as a result of architectural conjecture. To investigate this relationship, it is proposed to build a computer-supported collaborative design environment using the tools of conceptual modelling (based on the NIAM notation), object-oriented algorithms, and distributed agents. Based on a literature survey and earlier findings on the role of artifacts in collaborative design, this paper outlines the requirements for the above system and reports on initial experiments. Thus, it constitutes the first stage of a research project that will lead to a full implementation of a distributed collaborative computer environment addressing the above issues.

summary Architectural design is always concerned with form to things. It is the sphere or action where meanings are to be expressed and further on - received (by a receiver), felt, understood. "Meanings" mean not only rational information. The matter is to reach the essence and to master ways appropriate to expose and interprete it. Quality of the form decides whether architectural or any work is worth attention or not and to what degree. Form is an attribute of a thing. It is form that "speaks". This linguistic metaphore shows one of natural, inborn features of things and states. However, questions appear: 1. Does everything have form? 2. Is the form an objective term? 3. What limitations of the definition of the form to accept- if any? The friendly environment for creating form consists of conscious intentions plus open mind. Rules are certain, but liquid. Every formal communication system may be widened individually. The only limitation is to be received according to intentions. So, incredibly, the infinite number of combinations, even within one system, may be possible.

summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

summary It has been said that "The beginning of architecture is empty space." (Mitchell 1990) This statement typifies a design education philosophy in which the concepts of space and form are separated and defined respectively as the negative and positive of the physical world, a world where solid objects exist and void-the mere absence of substance-is a surrounding atmospheric emptiness. Since the beginning of the nineteenth century, however, there has been an alternative concept of space as a continuum: that there is a continuously modified surface between the pressures of form and space in which the shape of the space in our lungs is directly connected to the shape of the space within which we exist. (Porter 1979). The nature of the task of representing architecture alters to reflect the state of architectural understanding at each period of time. The construction of architectural space and form represents a fundamental achievement of humans in their environment and has always involved effort and materials requiring careful planning, preparation, and forethought. In architecture there is a necessary conversion to that which is habitable, experiential, and functional from an abstraction in an entirely different medium. It is often an imperfect procedure that centers on the translation rather than the actual design. Design of the built environment is an art of distinctions within the continuum of space, for example: between solid and void, interior and exterior, light and dark, or warm and cold. It is concerned with the physical organization and articulation of space. The amount and shape of the void contained and generated by the building create the fabric and substance of the built environment. Architecture as a design discipline, therefore, can be considered as a creative expression of the coexistence of form and space on a human scale. As Frank Ching writes in Architecture: Form, Space, and Order, "These elements of form and space are the critical means of architecture. While the utilitarian concerns of function and use can be relatively short lived, and symbolic interpretations can vary from age to age, these primary elements of form and space comprise timeless and fundamental vocabulary of the architectural designer." (1979)

title Data representations in an integrated architectural design environment
source University of Strathclyde, Dept. of Architecture and Building Science
summary The architectural design process is very complex and involves cross-disciplinary communication among many related fields. Given the further problems arising from the technological advances in building materials and construction methods, an integrated design environment becomes a central design issue. There have been many attempts to analyse and structure the design process as a uniform hierarchical framework. Most of the attempts resulted in a vague and inappropriate outcome due to the lack of understanding of architectural design complexity and inconsistent design data control sequence. A design problem cannot be comprehensively stated because the design problem has a multi-disciplinary nature and the design problem itself evolves as solutions are attempted by the designer. Therefore, an ideal CAAD system should have the capability to accommodate the multi-disciplinary nature of design and should not prescribe or restrict design concepts and design knowledge. A well designed integrated design environment provides more information and invokes creative imagination for each design stage, and therefore creative decision making by the designer can be achieved. This thesis proposes a prototype architectural design environment, Hybrid Integrated Design Environment [HIDE], which aims to integrate all applications for designing a building. Within the object-oriented design environment, a unified data model and a data management system have been implemented to seamlessly connect all applications. Development of the environment needs to consider the fundamental interaction between each module. Devising a data structure that is appropriate to an effective data communication among the various design stages is essential in a totally integrated CAAD system. The suggested unified data model organizes the structure of the design data to keep the design consistent throughout the design and construction process. By means of the unified data model, integrated CAAD systems could represent and exchange design information at a semantic level, i.e. the user’s way of thinking, such as exchanging components and features of a building rather than graphical primitives. In consequence, the unified data model reduces the misunderstandings and communication problems among the multiple disciplines of architectural design. The suggested data management system supports the consistent and straight forward mechanisms for controlling the data representation through the inter-connected modules. It is responsible for creating, maintaining, and viewing a consistent database of the design description. It also helps to perform effective data communication among the various design stages to ensure quality and time saving in the final construction of the building. To support inter-disciplinary communication of design concepts and decisions, the integrating of relevant CAAD tools is essential. In the environment, the integration of CAAD tools has been performed on the basis of how well computerized design tools can assist designers to develop better solutions, enabling them to manipulate and appraise varying solutions quickly and with a minimum of effort in an environment conducive to creative design. A well designed user interface system can also benefit the seamless working environment. The proposed user friendly interface system allows a user to explore the environment in a highly interactive manner. From the development of the early data model to the final design, a user could benefit from the prototypes and methods of the user interface system. The ultimate goal of the prototype environment is to suggest a future design environment which helps the architect to have minimum discontinuity in his creativity and make the design process similar to the natural design process with the help of a set of design assistance modules. A prototype version of HIDE has been implemented and a demonstration of the environment is part of this thesis.

summary The architectural design process is very complex and it is not easily confined to a single design environment. As the design process gets more complex due to the technological advances in building materials and construction methods, an integrated design system becomes a central design issue. To have an integrated design system, all applications should be integrated in a unified environment within which there should be a data structure to facilitate an effective data communication among the various design stages and data control facility to seamlessly connect all these applications. A primary purpose of this work is to suggest an object oriented architectural design environment for the essential part of the seamless environment for designing a building. Within the object-oriented design environment, a unified data model and detailed data control module have been implemented to seamlessly connect all these applications. The unified data model organizes the structure of the design data to keep the design consistent throughout the design and construction process. It also helps to do effective data communication among the various design stages to ensure quality and time saving in the final construction of the building. The data management module supports the consistent and easy mechanisms in controlling the data representation through the inter-connected modules. It is also responsible for creating, maintaining, and viewing a consistent database of the design description. In the suggested design environment, each architectural element partially describes the model and individual elements are aggregated hierarchically. Some parts of the projection are defined and other can be inherited from above. Also, creation of an improved or new design element can easily be accommodated in the environment. The integrated database in the suggested environment is the basis by which design data can be shared among the design tools of the design environment. The database organizes the design description within each representation, correlates equivalent descriptions across the representations, and attempts to maintain these correspondences as the design incrementally evolves.

summary The work described here is aimed at contributing towards the debate and development relating to the construction of interfaces to explore buildings and their environs through virtual worlds. We describe a particular hardware and software configuration which is derived by the use of low cost games software to create the Virtual Environment. The Physical Interface responds to the work of other researchers, in this area, in particular Shaw (1994) and Vasquez de Velasco & Trigo (1997). Virtual Evironments might have the potential to be "a magical window into other worlds, from molecules to minds" (Rheingold, 1992), but what is the nature of that window? Currently it is often a translucent opening which gives a hazy and distorted (disembodied) view. And many versions of such openings are relatively expensive. We consider ways towards clearing the haze without too much expense, adapting techniques proposed by developers of low cost virtual reality systems (Hollands, 1995) for use in an architectural setting.

title Sun and Time in the Built Environment
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, p. 248

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.
