summary	The research of applications concerning design, sizing and building of computer models have been, during the last years, undoubtedly of great importance and interest. Therefore, analyzing in detail the graphic packages concerning drafting and solid modelling we can undoubtedly say that these are nowadays an integral part of our daily work. In the near future, we can of course expect from those applications, new studies and research mainly concerning an easier start up and the standardization of the graphic interface; if we analyze, for example the well known package AutoCAD we can consider a new real data-base and the redesign of the interface on a graphic base (graphic choice of drawings and blocks, icons for commands, better capability of text editing, pattern editing and stretching, loading capability and visualization of various drawings in graphic windows, full compatibility with MS WINDOWS, etc. etc.). As above mentioned, these studies work on updating well known existing applications aiming to consolidate their uses; one specific section of design not yet supported by computer application is that related to the management of technical and non-technical information, nowadays still written and stored on paper.

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	Object oriented methods
source	Addison Wesley
summary	This is another book aimed at helping those making decisions to arrive at better informed ones. This is a second (and substantially updated)edition of a book that was deservedly well reviewed when it was originally published. Those who have to give advice on the choice of any aspect of OO technology from design to programming and testing will know that they are faced with attempting to make decisions based on ill-informed and often biased sources of information. Ian Graham attempts to survey the whole field, laying out your choices for you rather than making them for you. In each aspect of the subject the result of reading Object-Oriented Methods will be to allow you to reach decisions based on an understanding of the problems and the current range of tools aimed at helping you solve them. If you have a serious decision to make this would be a good place to start before proceeding to a more detailed investigation of what seem the potentially best choices for you and your needs. The other group of people who will benefit from reading this book are those that want or need a general overview of the OO arena. This is a good text that should be read by students of Computing, those who recognise that good advice is based on a comprehensive knowledge of the field and those who have to make a practical commercial decision about which OO route to take.

title	A First Step Towards an Intelligent Integrated Design System in the Building Field
source	computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered pages : ill. includes bibliography
summary	This article presents the work the Knowledge Base Group is achieving towards the integration of Artificial Intelligence based facilities in the Building design process. After an overview of the current state of the integrated design process, the context and the technical guidelines to realize computer integrated software in the building design field is described. Then some tools are presented to model the knowledge (the HBDS method) and to implement such model in our Mips home-made knowledge modeling software platform (including object-oriented database management facilities, expert system reasoning facilities, hypertext edition facilities, 3D-design and 3D-view modules...). Finally the authors describe the Quakes application devoted to assess detached house anti-seismic capabilities during the design process. A deep conceptual model considers all the semantic entities (columns, resistant panels, openings, ...) involved in the anti-seismic expertise. Using both this conceptual model description of a detached house and the 3D design tool, they input the project. Then the seismic expertise is driven in a divide and conquer approach and records the alleged configuration recognized automatically linked to the corresponding section of the building regulation

summary	Building IT2000 is a Building and Information Technology database which is presented in Hypertextformat. Its production has been co-ordinated by the CICA (the Construction Industry Computer Association), an independent association serving the needs of computer users, specifiers and suppliers in the Construction Industry. The stack is a collection of structured information prepared by a group of experts in computing and the construction industry. As such it represents an interesting advance from two points of view: (1.) It is a valuable source of information in its own right. It could provide a resource for students of architecture which could be used as a self-teaching package. (2.) It points a possible way forward for the development of similar hypertext based teaching packages which could be developed by academics within the European teaching community.

title	Building IT 2000 -- A Hypertext Database of Predictions on the Use of Information Technology in Building
source	The Computer Integrated Future, CIB W78 Seminar September, 1991. Unnumbered : ill.
summary	Hypertext is a medium particularly suitable for providing easy access to diverse information and maintaining it. It was used for a database of papers on the future of many aspects of information technology and their likely use by the year 2000. The recommendations include the development of project databases to integrate the use of computers by all parties to a building project, and the establishment of a building IT forum in the UK. CICA acted as research coordinator for the project and already carries out many of the functions of the building IT forum which will also need to include other organizations in the UK and in other countries. The data in Building IT 2000 will be maintained on hypertext and will take advantage of future developments in hypermedia. These new techniques, with the ability to provide selective access to, and payment for, digital data could help solve the problems of managing building project data. Building IT 2000 will be demonstrated at this conference to show its flexibility. It is available as a printed report or on disk for Macintosh or PC Windows 3.0 computers

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 169-177
summary	Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

title	The Reconstruction of the Past: The Application of New Techniques for Visualization and Research in Architectural History
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 549-566
summary	This paper focuses on the visualization of historical architecture. The application of new Computer-Aided- Architectural-Design techniques for visualization on micro computers provides a technique for reconstructing and analyzing architectural objects from the past. The pilot project describes a case study in which the historical transformation of a town will be analyzed by using three- dimensional CAD models in combination with bitmap textures. The transformation of the historic town will be visualized in a space-time computer model in which bitmap textures enable us to display complex and relatively large architectural objects in detail. This three-dimensional descriptive model allows us to survey and analyze the history of architecture in its reconstructed context. It also provides a medium for researching the dynamics of urban management, since new combinations and arrangements with the individual architectural objects can be created. In this way, a new synthesis of the graphic material can reveal typologies and the architectural ordering system of a town.

title	Design Tool Integration: Model Flexibility for the Building Profession
source	Proceedings of Building Systems Automation - Integration, University of Wisconsin-Madison
summary	The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by simulation tools, can be used to converse with knowledge-based systems. We consider the types of mappings that occur in the often different views of a building held by these two classes of design tools. This leads us to examine the need for multiple views of a common building model. We then extend our analysis from the views required by simulation and knowledge-based systems, to those required by different segments of the building profession (e.g. architects, engineers, developers, etc.) to converse with such an integrated system. This indicates a need to provide a flexible method of accessing data in the common building model to facilitate use by different building professionals with varying specialities and levels of expertise.

title	ICAtect: Integrating Design Tools for Preliminary Architectural Design
source	Wellington, New Zealand: Computer Science Department, Victoria University
summary	ICAtect is a knowledge based system that provides an interface between expert systems, simulation packages and CAD systems used for preliminary architectural design. This thesis describes its structure and development.The principal work discussed in this thesis involves the formulation of a method for representing a building. This is developed through an examination of a number of design tools used in architectural design, and the ways in which each of these describe a building.Methods of enabling data to be transferred between design tools are explored. A Common Building Model (CBM), forming the core of the ICAtect system, is developed to represent the design tools knowledge of a building. This model covers the range of knowledge required by a large set of disparate design tools used by architects at the initial design stage.Standard methods of integrating information from the tools were examined, but required augmentation to encompass the unusual constraints found in some of the design tools. The integration of the design tools and the CBM is discussed in detail, with example methods developed for each type of design tool. These example methods provide a successful way of moving information between the different representations. Some problems with mapping data between very different representations were encountered in this process, and the solutions or ideas for remedies are detailed. A model for control and use of ICAtect is developed in the thesis, and the extensions to enable a graphical user interface are discussed.The methods developed in this thesis demonstrate the feasibility of an integrated system of this nature, while the discussion of future work indicates the scope and potential power of ICAtect.

summary	To begin with, I would like to say a few words about the problem of alienation of modern technologies which we also inevitably faced while starting teaching CAD at our department. Quite often nowadays a technology becomes a fetish as a result of lack of clear goals in human mind. There are multiple technologies without sense of purpose which turned into pure experiments. There is always the danger of losing purposeness and drifting toward alienation. The cause of the danger lies in forgetting about original goals while mastering and developing the technology. Eventually the original idea is ignored and a great gap appears between technical factors and creativity. We had the danger of alienation in mind when preparing the CAAD curriculum. Trying to avoid the tension between technical and creative elements we agreed not to introduce CAD too soon then the fourth year of studies and continue it for two semesters. One thing was clear - we should not teach the technique of CAD but how to design using a computer as a medium. Then we specified projects. The first was called "The bathroom I dream of" and meant to be a 2D drawing. The four introductory meetings were in fact teaching foundations of DOS, then a specific design followed with the help of AutoCAD program. In the IX semester, for example, it was "A family house" (plans, facades, perspective). "I have to follow them - I am their leader" said L.J. Peter in "The Peter's Prescription". This quotation reflects exactly the situation we find ourselves in teaching CAAD at our department. It means that ever growing students interest in CAAD made us introduce changes in the curriculum. According to the popular saying, "The more one gets the more one wants", so did we and the students feel after the first semester of teaching CAD. From autumn 1991 CAAD classes will be carried from the third year of studying for two consecutive years. But before further planning one major steep had to be done - we decided to reverse the typical of the seventies approach to the problem when teaching programming languages preceded practical goals hence discouraging many learners.

title	Computer Exercises in Architectural Design Theory
doi	https://doi.org/10.52842/conf.ecaade.1991.x.f9w
source	Experiences with CAAD in Education and Practice [eCAADe Conference Proceedings] Munich (Germany) 17-19 October 1991
summary	This paper discusses how architectural theory may be taught using computer based exercises to explore the practical application of those theories. The particular view of architecture developed is, necessarily, a restricted one but the objectives behind the exercises are slightly different to those that a pure architectural theorist or historian might have The formal teaching of architectural theory and composition has not been very fashionable in Schools of Architecture for several years now: indeed there is a considerable inbuilt resistance in students to the application of any form of rules or procedures. There is however a general interest in computing and this can be utilised to advantage. In concentrating on computer applications in design eclectic use has been made of a number of architectural examples ranging from Greek temples to the work of modern deconstructionists. Architectural theory since Vitruvius is littered with attempts to define universal theories of design and this paper certainly does not presume to anything so grand: I have merely looked at buildings, compared them and noted what they have in common and how that might relate to computer-aided design. I have ignored completely any sociological, philosophical or phenomenological questions but would readily agree with the criticism that Cartesian rationality is not, on its own, a sufficient base upon which to build a theory of design. However I believe there is merit in articulating design by separating it from other concerns and making it a subject of study in its own right. Work in design research will provide the models and intellectual structures to facilitate discourse about design and might be expected to benefit the development of design skills by providing material that could be formally taught and debated in a way that is removed from the ephemeral "fashionable designer" debate. Of course, some of the ideas discussed here may prove to be equally ephemeral but that does not entirely negate their value.

title	Organizational Learning and Communities-of-Practice: Toward a Unified View of Working, Learning, and Innovation
source	Organization Science, 2(1), 40-57
summary	Recent ethnographic studies of workplace practices indicate that the ways people actually work usually differ fundamentally from the ways organizations describe that work in manuals, training programs, organizational charts, and job descriptions. Organizations tend to rely on the latter in their attempts to understand and improve work practice. We relate the conclusions of one study of work practices to compatible investigations of learning and innovation to argue that conventional descriptions of jobs mask not only the ways people work, but also the learning and innovation generated in the informal communities-of-practice in which they work. By reassessing the apparently conflicting triad of work, learning, and innovation in the context of actual communities and actual practices, we suggest that the synergistic connections between these three become apparent. With a unified view of working, learning, and innovating, it should be possible to reconceive of and redesign organizations to improve all three.

summary	Design can be considered a process leading to the definition of a physical form that achieves a certain predefined set of objectives. The process comprises three distinct operations: (1) definition of the desired set of performance criteria (design goals); (2) production of alternative design solutions; (3) evaluation of the expected performances of alternative design solutions, and comparing them to predefined criteria. Difficulties arise in performing each one of the three operations, as well as in combining them into a purposeful, unified process. First, it is difficult to define the desired performance criteria prior to and independently of, the search for an acceptable solution that achieves them, since many aspects of the desired criteria can only be discovered through the search for an acceptable solution. Furthermore, the search for such a solution may well alter the definition of these criteria, as new criteria and incompatibilities between existing criteria are discovered. Second the generation of a design solution is a task demanding creativity, judgement, and experience, all three of which are difficult to define, teach, and otherwise capture in some explicit manner. Third, it is difficult to evaluate the expected performances of alternative design solutions and to compare them to the predefined criteria. Design parameters interact with each other in complex ways, which cause effects and side effects. Predicting the expected performances of even primary effects involves extrapolating non-physical characteristics from the proposed solution's physical organization, a process which relies on a host of assumptions (physical, sociological, psychological, etc.) and hence is seldom a reliable measure. A fourth problem arises from the need to coordinate the three operations in an iterative process that will converge on an acceptable design solution in reasonable time. Computational techniques that were developed in the past to assist designers in performing the above mentioned activities have shown limitations and proved inadequate to a large degree. In this paper we discuss the work in progress aimed at developing an intelligent support system for building and architectural design, which will be able to play a decisive role in the definition, evaluation and putting into effect of the design choices.

title	Analogical and inductive reasoning in architectural design computation
source	Swiss Federal Institute of Technology, ETH Zurich
summary	Computer-aided architectural design technology is now a crucial tool of modern architecture, from the viewpoint of higher productivity and better products. As technologies advance, the amount of information and knowledge that designers can apply to a project is constantly increasing. This requires development of more advanced knowledge acquisition technology to achieve higher functionality, flexibility, and efficient performance of the knowledge-based design systems in architecture. Human designers do not solve design problems from scratch, they utilize previous problem solving episodes for similar design problems as a basis for developmental decision making. This observation leads to the starting point of this research: First, we can utilize past experience to solve a new problem by detecting the similarities between the past problem and the new problem. Second, we can identify constraints and general rules implied by those similarities and the similar parts of similar situations. That is, by applying analogical and inductive reasoning we can advance the problem solving process.The main objective of this research is to establish the theory that (1) design process can be viewed as a learning process, (2) design innovation involves analogical and inductive reasoning, and (3) learning from a designer's previous design cases is necessary for the development of the next generation in a knowledge-based design system. This thesis draws upon results from several disciplines, including knowledge representation and machine learning in artificial intelligence, and knowledge acquisition in knowledge engineering, to investigate a potential design environment for future developments in computer-aided architectural design. This thesis contains three parts which correspond to the different steps of this research. Part I, discusses three different ways - problem solving, learning and creativity - of generating new thoughts based on old ones. In Part II, the problem statement of the thesis is made and a conceptual model of analogical and inductive reasoning in design is proposed. In Part III, three different methods of building design systems for solving an architectural design problem are compared rule-based, example-based, and case-based. Finally, conclusions are made based on the current implementation of the work, and possible future extensions of this research are described. It reveals new approaches for knowledge acquisition, machine learning, and knowledge-based design systems in architecture.
