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 Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source New York: The Metropolitan Museum of Art
summary The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds http://www.learningsites.com. The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

summary The Protocol Analysis of the design process is a very recent and very promising research field. It is believed that good application-oriented developments are possible mainly in the tutorial field (ITS). The research conducted up to now has primarily dealt with the study of the design process. On the contrary, we propose an investigation experiment on the knowledge structures relative to the use of the episodic memory in the architectural design. The proposed experiment concerns the monitoring of the cognitive processes utilised by tutors and students in a brief, but yet complete design session. The results have lead to a synthetic model (computational model) of the adopted knowledge structures, and to a complete index system oriented and organised according to semantic fields. The application of the synthetic model to the design process analysis of students and tutors enabled the definition of the different utilisation strategies of episodic memory to be defined. The results obtained will make up the structure of a tutorial program for the architectural design.

title Redirecting design generation in architecture
source International Conference on Generative Art
summary Design generation has been the traditional culmination of computational design theory in architecture. Motivated either by programmatic and functional complexity (as in space allocation) or by the elegance and power of representational analyses (shape grammars, rectangular arrangements), research has produced generative systems capable of producing new designs that satisfied certain conditions or of reproducing exhaustively entire classes (such as all possible Palladian villas), comprising known and plausible new designs. Most generative systems aimed at a complete spatial design (detailing being an unpopular subject), with minimal if any intervention by the human user / designer. The reason for doing so was either to give a demonstration of the elegance, power and completeness of a system or simply that the replacement of the designer with the computer was the fundamental purpose of the system. In other words, the problem was deemed either already resolved by the generative system or too complex for the human designer. The ongoing democratization of the computer stimulates reconsideration of the principles underlying existing design generation in architecture. While the domain analysis upon which most systems are based is insightful and interesting, jumping to a generative conclusion was almost always based on a very sketchy understanding of human creativity and of the computer's role in designing and creativity. Our current perception of such matters suggests a different approach, based on the augmentation of intuitive creative capabilities with computational extensions. The paper proposes that architectural generative design systems can be redirected towards design exploration, including the development of alternatives and variations. Human designers are known to follow inconsistent strategies when confronted with conflicts in their designs. These strategies are not made more consistent by the emerging forms of design analysis. The use of analytical means such as simulation, couple to the necessity of considering a rapidly growing number of aspects, means that the designer is confronted with huge amounts of information that have to be processed and integrated in the design. Generative design exploration that can combine the analysis results in directed and responsive redesigning seems an effective method for the early stages of the design process, as well as for partial (local) problems in later stages. The transformation of generative systems into feedback support and background assistance for the human designer presupposes re-orientation of design generation with respect to the issues of local intelligence and autonomy. Design generation has made extensive use of local intelligence but has always kept it subservient to global schemes that tended to be holistic, rigid or deterministic. The acceptance of local conditions as largely independent structures (local coordinating devices) affords a more flexible attitude that permits not only the emergence of internal conflicts but also the resolution of such conflicts in a transparent manner. The resulting autonomy of local coordinating devices can be expanded to practically all aspects and abstraction levels. The ability to have intelligent behaviour built in components of the design representation, as well as in the spatial and building elements they signify, means that we can create the new, sharper tools required by the complexity resulting from the interpretation of the built environment as a dynamic configuration of co-operating yet autonomous parts that have to be considered independently and in conjunction with each other.   P.S. The content of the paper will be illustrated by a couple of computer programs that demonstrate the princples of local intelligence and autonomy in redesigning. It is possible that these programs could be presented as independent interactive exhibits but it all depends upon the time we can make free for the development of self-sufficient, self-running demonstrations until December.

title Toward a procedure of computer simulation in the restoration of historical architecture
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 the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

summary An extensive analysis of an architectural object or body leads to a model composed of abstractions, each reflecting on a different aspect. Though separately described through drawings, diagrams, and texts, these abstractions relate in many ways, most commonly through shared components. An integrated model that recognizes these relationships yields more than only the original abstractions. We present a methodology for achieving such a rich representation and touch upon the tools and techniques necessary to implement this methodology. As an application of this methodology, we describe an interactive educational system for the presentation of architectural analyses.

summary In general, computer-aided design is still limited to a rather elementary use of the medium, as it is mainly used for the representation/simulation of a design idea w an electronic drawing-table. hich is not computer-generated. The procedures used to date have been basically been those of an electronic drawing-table. At the first stage of development the objective was to find a different and better means of communication, to give form to an idea so as to show its quality. The procedures used were 2D design and 3D simulation models, usually used when the design was already defined. The second stage is when solid 3D modelling is used to define the formal design at the conception stage, using virtual models instead of study models in wood, plastic, etc. At the same time in other connected fields the objective is to evaluate the feasibility of the formal idea by means of structural and technological analysis. The third stage, in my opinion, should aim to develop procedures capable of contributing to both the generation of the formal idea and the simultaneous study of technical feasibility by means of a decision-making support system aided by an Artificial Intelligence procedure which will lead to what I would describe as the definition of the design in its totality. The approach to architectural and urban design has been strongly influenced by the first two stages, though these have developed independently and with very specific objectives. It is my belief that architectural design is now increasingly the result of a structured and complex process, not a simple act of pure artistic invention. Consequently, I feel that the way forward is a procedure able to virtually represent all the features of the object designed, not only in its definitive configuration but also and more importantly in the interactions which determine the design process as it develops. Thus A.I. becomes the means of synthesis for models which are hierarchically subordinated which together determine the design object in its developmental process, supporting decision-making by applying processing criteria which generative modelling has already identified. This trend is currently being experimented, giving rise to interesting results from process design in the field of industrial production.

summary The present graphic computer system allows defining high-level shape problems with great freedom. In free-form surface modeling it comes to be a good reason to develop an example that shows, which is the best way to create, modify and control complex free-form shapes in three-dimensional architectonic virtual modeling. The parameters of Bezier curves are not simple. But the use of Splines curves let us a friendly free form curves management with a great designer performance level. Unfortunately, the standard computer graphic tools to control these entities have a lot of variations, and normally create an unclear and confuse interface for generic users without several knowledge of mathematics and geometry. With the help of an example, this paper expose the use of computer graphics to make models of architectonic buildings with complex shapes that contains free-form surfaces. At the same time, it is an evaluation of how the standard CAD software processes this problem.

title Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source Delft University of Technology
summary The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title Generative music composition in practice - a critical evaluation
source International Conference on Generative Art
summary This critical evaluation will discuss 4 computer based musical works which, for reasons I shall explain, I describe as non-linear or generative. The works have been constructed by me and publicly performed or exhibited during a two year period from October 1998 to October 2000. ‘In the beginning…’ interactive music installation, strangeAttraction, Morley Gallery, London. July 1999 ‘jnrtv’ live generative dance music May 1999 to Dec 2000 ‘jazz’ interactive music installation, another strangeAttraction Morley Gallery, London. July 2000-09-26 ‘the street’ architectural interactive music installation, University of Westminster Oct 2000 Introduction I have always loved the practice of composing, particularly when it means scoring a work to be played by a live ensemble. There is something about taking a fresh sheet of manuscript , ruling the bar lines, adding clefs, key and time signatures and beginning the gradual process of adding notes, one at a time to the score until it is complete that is gratifying and compensates for the enormous effort involved. The process of scoring however is actually one distinct act within the more general task of creating music. Recently, the notion of ‘composing’ has met challenges through an increased interest in non-linear compositional methods. It is actually the presence of Chaotic or uncontrolable elements which add real beauty to music and many if not all of the things we value. If we think of a sunset, waves lapping on the shore, plants, trees a human face and the sound of the human voice, these things are not perfect and more importantly perhaps, they are transient, constantly changing and evolving. Last year and again this year, I have organised an exhibition of interactive , non-linear music installations called 'strangeAttraction'. The title refers to what Edward Lorenz called a ‘strange attractor’ the phenomenon that despite vast degrees of Chaos and uncertainty within a system, there is a degree of predictability, the tendency for chaotic behaviour to ‘attract’ towards a probable set of outcomes. Composition that deals with 'attractors' or probable outcomes rather than specific details which are set in stone is an increasingly intriguing notion.

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.

title Creative computer aided architectural design An internal approach to the design process
source University of Oulu (Finland)
summary This survey can be seen as quite multidisciplinary research. The basis for this study has been inapplicability of different CAD user interfaces in architectural design. The objective of this research is to improve architectural design from the creative problem-solving viewpoint, where the main goal is to intensify architectural design by using information technology. The research is linked to theory of methods, where an internal approach to design process means studying the actions and thinking of architects in the design process. The research approach has been inspired by hermeneutics. The human thinking process is divided into subconscious and conscious thinking. The subconscious plays a crucial role in creative work. The opposite of creative work is systematic work, which attempts to find solutions by means of logical inference. Both creative and systematic problem solving have had periods of predominance in the history of Finnish architecture. The perceptions in the present study indicate that neither method alone can produce optimal results. Logic is one of the tools of creativity, since the analysis and implementation of creative solutions require logical thinking. The creative process cannot be controlled directly, but by creating favourable work conditions for creativity, it can be enhanced. Present user interfaces can make draughting and the creation of alternatives quicker and more effective in the final stages of designing. Only two thirds of the architects use computers in working design, even the CAD system is being acquired in greater number of offices. User interfaces are at present inflexible in sketching. Draughting and sketching are the basic methods of creative work for architects. When working with the mouse, keyboard and screen the natural communication channel is impaired, since there is only a weak connection between the hand and the line being drawn on the screen. There is no direct correspondence between hand movements and the lines that appear on the screen, and the important items cannot be emphasized by, for example, pressing the pencil more heavily than normally. In traditional sketching the pen is a natural extension of the hand, as sketching can sometimes be controlled entirely by the unconscious. Conscious efforts in using the computer shift the attention away from the actual design process. However, some architects have reached a sufficiently high level of skill in the use of computer applications in order to be able to use them effectively in designing without any harmful effect on the creative process. There are several possibilities in developing CAD systems aimed at architectural design, but the practical creative design process has developed during a long period of time, in which case changing it in a short period of time would be very difficult. Although CAD has had, and will have, some evolutionary influences on the design process of architects as an entity, the future CAD user interface should adopt its features from the architect's practical and creative design process, and not vice versa.

title Setting objects to work: adding functionality to an architectural object model
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary Several research initiatives in the field of product modelling have produced static descriptions of the architectural and geometrical objects capable of describing architectural design projects. Less attention is paid to the development phase in which these static models are transformed into workable architectural design environments. In the context of the IDEA+ research project (Integrated Design Environment for Architectural Design), we use the object-oriented analysis method MERODE to develop and describe both an enterprise (or product) model and a functionality model. On the one hand, the enterprise model defines the architectural and geometrical objects, their methods and their relation with other objects. On the other hand, the functionality model organizes the functionality objects – ranging from single-event objects to complex-workflow objects – in a layered and easily expandable system. The functionality model is created on top of the enterprise model and closes the gap between the static enterprise model and the dynamic design environment as a whole. After a short introduction of the envisaged design environment and its underlying enterprise model, the paper will concentrate on the presentation of the higher-level functionality model. Elaborated examples of functionality objects on the different levels will clarify its concepts and proof its feasibility.

summary Several product-modelling initiatives have produced static descriptions of the architectural and geometrical objects capable of describing architectural design projects. Less attention is paid to the development phase in which these static models are transformed into workable architectural design environments. In the context of the IDEA+ research project (Integrated Design Environment for Architectural Design) emphasis lies on the systematic development of both phases. The result is an analysis model that consists of two submodels. On the one hand, the enterprise model defines the architectural and geometrical objects, their methods and their relation with other objects. On the other hand, the functionality model organises the functionality objects - ranging from single-event objects to complex-workflow objects - in a layered and easily expandable system. As such, it closes the gap between the static enterprise model and the dynamic design environment as a whole.

source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 370-373
summary Leeds Metropolitan University is well placed to carry out research into multi-disciplinary team-working, as all the design and construction disciplines are housed in one faculty. Staff have set up an experimental project, TIME IT (Team-working in Multi-disciplinary Environments using IT) which examines ways of working in the design/construction process and how IT is used when there is no commercial pressure. Four groups of four students, one graduate diploma architect, and one final year student from each of Civil Engineering, Construction Management and Quantity Surveying have been working on feasibility studies for projects that are based on completed schemes or have been devised by collaborators in the Construction Industry. Students have been asked to produce a PowerPoint presentation, in up to five working days, of a design scheme, with costs, structural analysis and construction programme. The students are not assessed on the quality of the product, but on their own ability to monitor the process and use of IT. Despite this, aggressive competition evolved between the teams to produce the 'best' design. Five projects were run in the 1998/99 session. A dedicated IT suite has been provided; each group of students had exclusive use of a machine. They were not told how to approach the projects nor when to use the available technology, but were asked to keep the use of paper to a minimum and to keep all their work on the server, so that it could be monitored externally. Not so. They plotted the AO drawings of an existing building that had been provided on the server. They like paper - they can scribble on it, fold it, tear it and throw it at one another.

title Forming and automated energy analysis of integrated models of the public buildings and their enclosing structures
source Civil Engineering, 6(3), pp. 147-157
summary The article concerns the modelling and energy analysis problem of the spatial and structural solutions of newly designed buildings or those under renovation. The results of that task serve as a base for defining thermal indices of the project on different design stages. The core of the developed automated system is formed of integrated graphical digital spatial models of the parts of buildings. These models include different kind of structured geometric and non-geometric (physical, economical) information about the object. The proposed method could be used by interested experts as a tool for controll thermal and energy indices at various design stages, searching for rational architectural forms and structural solutions. It takes into account the latest requirements of Lithuanian building regulations concerning heating energy saving.

title Daylight Simulation: Validation, Sky Models and Daylight Coefficients
source De Montfort University, Leicester, UK
summary The application of lighting simulation techniques for daylight illuminance modelling in architectural spaces is described in this thesis. The prediction tool used for all the work described here is the Radiance lighting simulation system. An overview of the features and capabilities of the Radiance system is presented. Daylight simulation using the Radiance system is described in some detail. The relation between physical quantities and the lighting simulation parameters is made clear in a series of progressively more complex examples. Effective use of the inter-reflection calculation is described. The illuminance calculation is validated under real sky conditions for a full-size office space. The simulation model used sky luminance patterns that were based directly on measurements. Internal illuminance predictions are compared with measurements for 754 skies that cover a wide range of naturally occurring conditions. The processing of the sky luminance measurements for the lighting simulation is described. The accuracy of the illuminance predictions is shown to be, in the main, comparable with the accuracy of the model input data. There were a number of predictions with low accuracy. Evidence is presented to show that these result from imprecision in the model specification - such as, uncertainty of the circumsolar luminance - rather than the prediction algorithms themselves. Procedures to visualise and reduce illuminance and lighting-related data are presented. The ability of sky models to reproduce measured sky luminance patterns for the purpose of predicting internal illuminance is investigated. Four sky models and two sky models blends are assessed. Predictions of internal illuminance using sky models/blends are compared against those using measured sky luminance patterns. The sky model blends and the Perez All-weather model are shown to perform comparably well. Illuminance predictions using measured skies however were invariably better than those using sky models/blends. Several formulations of the daylight coefficient approach for predicting time varying illuminances are presented. Radiance is used to predict the daylight coefficients from which internal illuminances are derived. The form and magnitude of the daylight coefficients are related to the scene geometry and the discretisation scheme. Internal illuminances are derived for four daylight coefficient formulations based on the measured luminance patterns for the 754 skies. For the best of the formulations, the accuracy of the daylight coefficient derived illuminances is shown to be comparable to that using the standard Radiance calculation method. The use of the daylight coefficient approach to both accurately and efficiently predict hourly internal daylight illuminance levels for an entire year is described. Daylight coefficients are invariant to building orientation for a fixed building configuration. This property of daylight coefficients is exploited to yield hourly internal illuminances for a full year as a function of building orientation. Visual data analysis techniques are used to display and process the massive number of derived illuminances.

title A proposal for alternative methods for teaching digital design
source Automation in Construction 9 (1) (2000) pp. 19-35
summary Computers have the potential to radically change the process of architectural design, and match more closely the formal aspirations of contemporary designers. What, then, should be the direction educators take in response to the opportunities created by the use of computers in the design process? There are, perhaps, two obvious methods of teaching Digital Design at a university level; a course adjunct to a design studio, or a course offered independently of a design studio. The computer is a facilitator of design ideas, but by itself, is not a creator of content. The primary responsibility of the design studio is the creation of content. It is the implementation of theory and critical analysis which should be the core concern of studio instruction. Given the limited time students are exposed to design studio it would seem appropriate, then, that the digital tools, which facilitate the design process, be taught separately, so as not to dilute the design studios importance. Likewise, this separation should allow the student to concentrate attention on Digital Design as a comprehensive process, beginning with initial massing studies and ending with high resolution presentation drawings. The burden of learning this new process is difficult as well as time consuming. Students are generally struggling to learn how to design, much less to design on the computer. In addition, the current lack of digital skills on the part of design faculty makes it difficult to create a level of consistency in teaching digital design. Compounding these problems is the cost to architectural departments of providing hardware and software resources sufficient to have a computer on every studio desk.

summary This paper describes the development of a multimedia system called ADMIRE (an Architectural Design Multimedia Interaction Resource for Education), which enables undergraduate students to understand how to analyse existing buildings dynamically, as well as to develop their own initial architectural design theories. The system contains architectural information in the form of fully rendered models, conceptual illustrations created with a range of CAD software, and multimedia presentations showing various design theoretic analyses. Buildings are described with CAD generated images, and architects with profiles and theories. In addition to rendered designs, there are also conceptual models of each building in the system. Conceptual models are simplified forms of original designs in order to support an analytical understanding of buildings according to various analyses, such as structure, light, circulation, unit to whole, geometry, etc. Each conceptual model constitutes a different analysis of each building. The ADMIRE system links each piece of information to another, so that students can explore architecture and learn about it in a dynamic way. This system demonstrates a new way of learning about architectural analysis through dynamic multimedia computer interaction.

summary Computer applications in design have pursued two main development directions: analytical modelling and information technology. The former line has produced a large number of tools for reality simulation (i.e. finite element models), the latter is producing an equally large amount of advances in conceptual design support (i.e. artificial intelligence tools). Nevertheless we can trace rare interactions between computation models related to those different approaches. This lack of integration is the main reason of the difficulty of CAAD application to the preliminary stage of design, where logical and quantitative reasoning are closely related in a process that we often call 'qualitative evaluation'. This paper briefly surveys the current development of qualitative physical models applied in design and propose a general approach for modelling physical behaviour by means of Bayesian network we are employing to develop a tutoring and coaching system for natural ventilation preliminary design of halls, called VENTPad. This tool explores the possibility of modelling the causal mechanism that operate in real systems in order to allow a number of integrated logical and quantitative inference about the fluid-dynamic behaviour of an hall. This application could be an interesting connection tool between logical and analytical procedures in preliminary design aiding, able to help students or unskilled architects, both to guide them through the analysis process of numerical data (i.e. obtained with sophisticate Computational Fluid Dynamics software) or experimental data (i.e. obtained with laboratory test models) and to suggest improvements to the design.
