title	The Re-Convergence of Art and Science: A Vehicle for Creativity
doi	https://doi.org/10.52842/conf.caadria.2000.491
source	CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 491-500
summary	Ever-increasing complexity in product design and the need to deliver a cost-effective solution that benefits from a dynamic approach requires the employment and adoption of innovative design methods which ensure that products are of the highest quality and meet or exceed customers' expectations. According to Bronowski (1976) science and art were originally two faces of the same human creativity. However, as civilisation advances and works became specialised, the dichotomy of science and art gradually became apparent. Hence scientists and artists were born, and began to develop work that was polar opposite. The sense of beauty itself became separated from science and was confined within the field of art. This dichotomy existed through mankind's efforts in advancing civilisation to its present state. This paper briefly examines the relationship between art and science through the ages and discusses their relatively recent re-convergence. Based on this hypothesis, this paper studies the current state of the convergence between arts and sciences and examines the current relationship between the two by considering real world applications and products. The study of such products and their successes and impact they had in the marketplace due to their designs and aesthetics rather than their advanced technology that had partially failed them appears to support this argument. This text further argues that a re-convergence between art and science is currently occurring and highlights the need for accelerating this process. It is suggested that re-convergence is a result of new technologies which are adopted by practitioners that include effective visualisation and communication of ideas and concepts. Such elements are widely found today in multimedia and Virtual Environments (VEs) where such tools offer increased power and new abilities to both scientists and designers as both venture in each other's domains. This paper highlights the need for the employment of emerging computer based real-time interactive technologies that are expected to enhance the design process through real-time prototyping and visualisation, better decision-making, higher quality communication and collaboration, lessor error and reduced design cycles. Effective employment and adoption of innovative design methods that ensure products are delivered on time, and within budget, are of the highest quality and meet customer expectations are becoming of ever increasing importance. Such tools and concepts are outlined and their roles in the industries they currently serve are identified. Case studies from differing fields are also studied. It is also suggested that Virtual Reality interfaces should be used and given access to Computer Aided Design (CAD) model information and data so that users may interrogate virtual models for additional information and functionality. Adoption and appliance of such integrated technologies over the Internet and their relevance to electronic commerce is also discussed. Finally, emerging software and hardware technologies are outlined and case studies from the architecture, electronic games, and retail industries among others are discussed, the benefits are subsequently put forward to support the argument. The requirements for adopting such technologies in financial, skills required and process management terms are also considered and outlined.

title	Java collaborative interface for architectural simulations A case study on wooden ceilings of Krakow
source	International Conference On Conservation - Krakow 2000, 23-24 November 1998, Krakow, Poland
summary	Concern for the architectural and urban preservation problems has been considerably increasing in the past decades, and with it the necessity to investigate the consequences and opportunities opened for the conservation discipline by the development of computer-based systems. Architectural interventions on historical edifices or in preserved urban fabric face conservationists and architects with specific problems related to the handling and exchange of a variety of historical documents and representations. The recent development of information technologies offers opportunities to favour a better access to such data, as well as means to represent architectural hypothesis or design. Developing applications for the Internet also introduces a greater capacity to exchange experiences or ideas and to invest on low-cost collaborative working platforms. In the field of the architectural heritage, our research addresses two problems: historical data and documentation of the edifice, methods of representation (knowledge modelling and visualisation) of the edifice. This research is connected with the ARKIW POLONIUM co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France) and the Institute HAiKZ of Kraków's Faculty of Architecture. The ARKIW programme deals with questions related to the use of information technologies in the recording, protection and studying of the architectural heritage. Case studies are chosen in order to experience and validate a technical platform dedicated to the formalisation and exchange of knowledge related to the architectural heritage (architectural data management, representation and simulation tools, survey methods, ...). A special focus is put on the evolution of the urban fabric and on the simulation of reconstructional hypothesis. Our contribution will introduce current ARKIW internet applications and experiences: The ARPENTEUR architectural survey experiment on Wie¿a Ratuszowa (a photogrammetrical survey based on an architectural model). A Gothic and Renaissance reconstruction of the Ratusz Krakowski using a commercial modelisation and animation software (MAYA). The SOL on line documentation interface for Kraków's Rynek G_ówny. Internet analytical approach in the presentation of morphological informations about Kraków's Kramy Bogate Rynku Krakowskiego. Object-Orientation approach in the modelling of the architectural corpus. The VALIDEUR and HUBLOT Virtual Reality modellers for the simulation and representation of reconstructional hypothesis and corpus analysis.

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	Possibilities and limitations of CFD simulation for indoor climate analysis
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	With the democratization of information and communication technologies, simulation techniques that used to be computationally expensive and time-consuming are becoming feasible instruments for the analysis of architectural design. Simulation is an indispensable ingredient of the descriptive design approach, which provides the designer with precise and accurate projections of the performance and behavior of a design. The paper describes the application of a particular class of simulation techniques, computational fluid dynamics (CFD), to the analysis and evaluation of indoor climate. Using two different CFD systems as representatives of the class, we describe: relevant computational possibilities and limitations of CFD simulation; the accessibility of CFD simulation for architects, especially concerning the handling of simulation variables; the compatibility of CFD representations of built space with similar representations in standard CAD and modeling systems, including possibilities for feedback; The relations between geometric representation and accuracy / precision in CFD simulation. We propose that CFD simulation can become an operational instrument for the designer, provided that CFD simulation does not become a trial and error game trying to master computational techniques. A promising solution to this problem is the use of case based reasoning. A case base of analyzed, evaluated and verified buildings provides a flexible source of information (guidance and examples) for both the CFD simulation and the designer.

title	Learning from Experience: Promises, Problems and Side-effects of CBD in Architecture
doi	https://doi.org/10.52842/conf.ecaade.1999.567
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 567-575
summary	Learning from design experience is the essence of Case-Based Design (CBD). Because architects are said to learn design by experience, CBD seems to hold great promises for architectural design, which have inspired various CBD tools. Learning from the experience of developing and using these tools is the objective of this paper. On the one hand, the original expectations seem far from being accomplished today. Reasons for this limited success can be found at three different levels. Level one is the cognitive model underlying CBD, which raises some specific difficulties within the field of architecture. At the level of implementation, few tools manage to draw the full consequences of this view, thus leading to an oversimplification of CBD and/or architectural design. Level three has to do with introducing CBD tools in design education and assessing the effects of this introduction. On the other hand, CBD seems to have caused some interesting side effects, such as an increased interest in creativity and copyright, and the recent re-discovery of the key-role cases play inside and outside the field of CAAD. Thus, although its promises may not be fulfilled, CBD definitely can contribute to design education, be it sometimes without the support of computer technology.

title	DYNAMO - Dynamic Architectural Memory On-line
source	Educational Technology and Society, Vol.3, No.2, April 2000 (ISSN 1436-4522), pp. 86-95
summary	This paper describes the current status of DYNAMO, a web-based design assistant for students and professional designers in the field of architecture. The tool can be considered a Case-Based Design (CBD) system in so far that it was inspired by the view of cognition underlying CBD. The paper points out how DYNAMO incorporates this view, and at the same time extrapolates it beyond the individual. In this way, the tool attempts to embrace and profit from several kinds of interaction that are crucial for the development and renewal of design knowledge. This should result in a design tool that both feels cognitively comfortable to (student-) designers, and offers them a platform for exchanging knowledge and insights with colleagues in different contexts and at different levels of experience. In addition, the paper describes the implementation of these theoretical ideas as a working prototype, which has recently been tested by 4th year design students. Finally, DYNAMO is situated in the context of other comparable tools that have been or are being developed in the field of architectural design.

title	Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

title	The E-Talier: Inter-university Networked Design Studios
doi	https://doi.org/10.52842/conf.ecaade.2000.045
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 45-50
summary	The widespread infiltration of internet based variations of traditional areas of society (e-commerce, e-business, e-mail etc.) will not spare the halls of academia in its propagation. The term courseware is well nigh 20 years old and considerable research and development has been done in bringing network based distributed courses to university consortiums including those in architecture and civil engineering. Indeed, the European Commission has recently approved funding for a 3-year web-based virtual university of architecture and construction technology: the WINDS project led by the University of Ancona. Such attempts to create e-courses are largely an extension of typical courseware where the syllabus is quantified and divided into lessons for use by the students alone or in conjunction with their tutors and professors. This is quite adequate in conveying the base knowledge of the profession. However, the tenants of being an architect or engineer involve the deft use of that unwieldy named and deliciously imprecise tool called "design". Teaching design sooner or later involves the design studio: a pedagogically construed environment of simulation intended to train, not teach the skills of designing. This is fundamentally different from normal courseware. A network based design studio (Etalier) must be able to reflect the nature of learning design. Design studios typically involve specifically chosen design problems, researched supporting information to assist design decisions, focussed discussions, individual consultation and criticism, group criticism, public forums for presentation discussion and criticism as well as a myriad of informal undocumented communication among the students themselves. So too must an Etalier function. Essentially, it must allow collaboration through communication. Traditional barriers to collaboration include language, culture (both national and professional) and distance. Through the internet's capricious growth and the widespread use of English as a second language, the largest hurdle to attaining fruitful collaboration is probably cultural. In the case of an Etalier in a university setting, the cultural difficulties arise from administrative rules, the pedagogical culture of specific universities and issues such as scheduling and accreditation. Previous experiments with virtual design studios have demonstrated the criticality of such issues. The proposed system allows participating members to specify the degree and breadth with which they wish to partake. As opposed to specifying the conditions of membership, we propose to specify the conditions of partnership. Through the basic principal of reciprocity, issues such as accreditation and work load sharing can be mitigated. Further, the establishment of a studio market will allow students, tutors and professors from participating institutions to partake in studio projects of their choosing in accordance with their own constraints, be they related to schedule, expertise, legal or other matters. The paper describes these mechanisms and some possible scenarios for collaboration in the Etalier market.

title	Computing and Problem Based Learning at Delft University of Technology Faculty of Architecture
doi	https://doi.org/10.52842/conf.ecaade.1992.289
source	CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 289-294
summary	Delft University of Technology, founded in 1842, is the oldest and largest technical university in the Netherlands. It provides education for more than 13,000 students in fifteen main subject areas. The Faculty of Architecture, Housing, Urban Design and Planning is one of the largest faculties of the DUT with some 2000 students and over 500 staff members. The course of study takes four academic years: a first year (Propaedeuse) and a further three years (Doctoraal) leading to the "ingenieur" qualification. The basic course material is delivered in the first two years and is taken by all students. The third and fourth years consist of a smaller number of compulsory subjects in each of the department's specialist areas together with a wide range of option choices. The five main subject areas the students may choose from for their specialisation are Architecture, Building and Project Management, Building Technology, Urban Design and Planning, and Housing. The curriculum of the Faculty has been radically revised over the last two years and is now based on the concept of "Problem-Based Learning". The subject matter taught is divided thematically into specific issues that are taught in six week blocks. The vehicles for these blocks are specially selected and adapted case studies prepared by teams of staff members. These provide a focus for integrating specialist subjects around a studio based design theme. In the case of second year this studio is largely computer-based: many drawings are produced by computer and several specially written computer applications are used in association with the specialist inputs. This paper describes the "block structure" used in second year, giving examples of the special computer programs used, but also raises a number of broader educational issues. Introduction of the block system arose as a method of curriculum integration in response to difficulties emerging from the independent functioning of strong discipline areas in the traditional work groups. The need for a greater level of selfdirected learning was recognised as opposed to the "passive information model" of student learning in which the students are seen as empty vessels to be filled with knowledge - which they are then usually unable to apply in design related contexts in the studio. Furthermore, the value of electives had been questioned: whilst enabling some diversity of choice, they may also be seen as diverting attention and resources from the real problems of teaching architecture.

summary	This paper describes a project within the authors’ ongoing research in the field of Generative Design. The work is based on the premise that computer-aided design (CAD) should evolve beyond its current limitation of one-way interaction, and become a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customized designs which exhibit common features. The authors describe this idea by illustrating the implementation of a research project, which explores the notions of mass-customization in design by using evolutionary and parametric methods to generate families of simple objects, in our case a door handle. The project examines related approaches using both complex CAD/CAM packages (CADDS, CATIA) and a proprietary software tool for evolutionary design. The paper first gives a short historical and philosophical background to the work, then describes the technical and algorithmic requirements, and concludes with the implementations of the project.

title	Hearing Architectural Design: Simulation and Auralization for Generating Better Acoustic Spaces
source	International Conference on Generative Art
summary	This paper with demonstration is devoted to revealing and establishing the relationship between space and sound through computational acoustic analysis, simulation and electronic synthesis of audible sound. Based on science of acoustics and computing technology, acoustic effect of an architectural 3-D design can be analyzed and the resulted sound in space can be synthesized and predicted accordingly and being heard. Auralization refers to this process of acoustic analysis, sound synthesis and audio presentation of the result in the form of audible sound. Design alternatives can be experimented until satisfactory acoustic effect is achieved. Traditionally, designers rely on some minimum and vague understanding or specialists’ experiences to predict and design for a desirable sound behavior in spaces. Most likely acoustic design and analysis are seen as a luxury remedy only affordable in large-scale theatres and concert halls. The recent available PC based auralization tools brought significance in both in terms of new knowledge towards the science and art of architectural acoustics and the methods and practice in the design process. The examples demonstrated in the presentation will indicate that the auralization technology make it possible for the designers, consultants, end users or potential occupants to examine and evaluate the performance of different designs by hearing it directly before an informed decision can be made. The case studies also illustrated that the auralization is a powerful tool for general public with common building types to uncover everyday acoustic problems that have been constantly harming their well being and would otherwise be undetected.

title	Retrieval Tools in Building Case Bases
doi	https://doi.org/10.52842/conf.ecaade.2000.113
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 113-116
summary	Most of the existing aids to building design rely on data base of cases representing solutions to problems that are thought to happen again at least in a similar way. Crucial for the success of the aid is the retrieval engine. In tour its efficiency depends on the way the cases are encoded. Whichever is this way cases will be represented at different levels of abstraction. The highest level will probably consist in an accessibility and adjacency graph. Another level could be a wire plan of the building. An easily workable representation of a graph is a square matrix. For any given building typology it is possible to write a list of encoded space types. This allows forming matrices that can be compared and their diversity measured. Here we present an algorithm that makes this job. Such an algorithm can be one of the case retrieval tools in the data base. It is likely that the designer has already some idea of the shape he wants for the building he is designing. A comparison between some geometric characteristics of the wire representation of the retrieved case and the corresponding ones of the imagined solution of the design problem can constitute a second test. The matching can be done

source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	The spread of the Internet has spurred the recent growth in e-commerce. E-commerce impinges on design in many ways, not least in encouraging the development of new tools for the presentation of product information: that is, information about the products that are used in design projects. (In the case of building design this might include information about standard doors, windows and fittings.) In this paper we present our development of three experimental tools for presenting and organising product information. The tools represent stages in the evolution of a prototype we call PLA(id) (Product Library Assistant – Intranet for Designers) involving the use of multimedia authoring, Java, and mobile computing. We discuss our experimental prototypes under several headings derived from what are commonly considered the key features of e-commerce: the marketplace, collaboration (the electronic marketplace as a community), geography (and geographical boundaries), navigation, regulation, integration and media (how in some cases e-commerce provides both the medium of transaction and the medium of delivery). So this account of our experimentation with product information tools provides a way of reviewing issues raised by e-commerce and their importance for design decision support systems.

summary	This paper examines the progressive and pragmatic use of computers and CAAD systems in the architectural practice. With the aid of three scenarios, this paper will illustrate gainful implementation of computer aided project planning in architecture. The first scenario describes an actual situation of implementation and describes conceptual abortive developments in office organization as well as in software technology. Scenario two outlines the essential features of an integrated building design system and the efforts involved in its implementation in the architectural practice. It clearly defines preconditions for implementation and focuses on feasible concepts for the integration of different database management systems. A glance at paradigms of conceptual work currently under development will be taken. The third scenario deals with the structure and integration of innovative concepts and the responsibility the architect will bear with regard to necessary alterations in office and workgroup organization. A future-oriented building design system will be described that distinguishes itself from existing programs because of its modular, net-based structure. With reference to today’s situation in architectural offices and according to realizable improvements, this article will demonstrate courses for future IT-support on the basis of an ongoing research project. The presented project is part of the special research area 524 “Materials and Constructions for the Revitalization of Existing Buildings” which is funded by the Deutsche Forschungsgemeinschaft. It deals with the integration of various parties that are involved in the revitalization process of existing buildings as well as with the provision of adequate information within the planning process resting upon the survey of existing building substance. Additional concepts that might change the way an architect’s work is organized will also be presented. “Case-based-reasoning” methods will make informal knowledge available, leading to a digital memory of preservable solutions.

title	Object-Oriented Application Development in CAD
source	Technical Report 48-01-01. Pittsburgh, PA: Carnegie Mellon University, Institute of Complex Engineered Systems
summary	This report describes a graduate interdisciplinary course offered to students in the graduate program of the School of Architecture at Carnegie Mellon and related departments in fall 2000. The motivation was the realization that when commercial CAD (Computer-Aided Design) systems recently switched from procedural application programming languages to object-oriented ones, third-party application must undergo a significant cognitive retooling"; i. e. they must know more than the syntax and semantics of the new programming language to be used and must be able to employ appropriate software development strategies that are appropriate for the new paradigm. especially with respect to the importance of modeling, a distinguishing characteristic of object-oriented programming. The goal of the course was (a) to introduce and test strategies of object-oriented application development in general and in the context of MicroStation, a state-of-the-art commercial CAD package; (b) to develop-as a course team project-an interesting application that gives students practice with these strategies and team work; and (c) to document our approach and findings so that others can learn from them. The strategies introduced were the use-case approach of Jacobson et al. and the complementary object-modeling tools of Rumbaugh that were recently integrated into the Unified Modeling Language UML. The software platform supporting the course comprised MicroStation, JMDL (a superset of Java) and ProjectBank on the CAD side and RationalRose on the modeling side. The application developed by students in the course supports the generation of drawings for remodeling projects from a set of dgn files describing the existing state of the building to be remodeled. The course was supported by a grant and in-kind contributions from Bentley with matching funds from the Pennsylvania Infrastructure Technology Alliance (PITA)."

title	COMPUTER-MEDIATED COMMUNICATION IN DESIGN
source	PhD Thesis, Faculty of Architecture, University of Sydney
summary	Up till now, architects collaborating with other colleagues did so mostly face-to-face (FTF). They had to be in the same space (co-located) at the same time. Communication was ‘spontaneous’ and ideas were represented, whether verbal or nonverbal, by talking and using ‘traditional drawing tools’. If they were geographically displaced, the interaction was then space affected as well as the probability of being time affected. In this case communication was usually mediated through the telephone, and graphically represented ideas were sent by Fax or posted documents. Recently, some architectural firms started using modems and Internet connections to exchange information, by transferring CAD drawings as well as design information, through e-mail and file transfer protocol (FTP). Discussing ideas in architecture, as a more abstract notion, is different from discussing other more concrete arguments using video conferencing. It is more important to ‘see’ what is being discussed at hand than ‘watch’ the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the mode of communication. Taking into consideration recent developments in computer and communication technologies this thesis investigates different communication channels utilised in architectural collaboration through Computer Mediated Collaborative Design (CMCD) sessions as opposed to FTF sessions. This thesis investigates the possible effects these different channels have on collaborative design in general and collaborative design communication in particular. We argue that successful CMCD does not necessarily mean emulating close proximity environments. Excluding certain communication channels in a CMCD environment might affect the flow and quantity of synchronous collaborative communication, but not necessarily the quality and content of mutually communicated and represented design ideas. Therefore different communication channels might affect the type of communication and not necessarily the content of the communication. We propose that audio and video are not essential communication channels in CMCD environments. We posit that architects will collaborate and communicate design representations effectively although with some differences, since those two channels might cause interruptions and successful collaborative sessions can take place without them. For this purpose we conducted twenty-four one-hour experiments involving final year architecture students all working to the same design brief. The experiments were divided into three categories, FTF, full computer mediated collaborative design sessions (CMCD-a; audio-video conferencing plus whiteboard as a shared drawing space) and limited computer mediated collaborative design sessions (CMCD-b; with Lambda MOO used as a chat medium plus whiteboard as a shared drawing space). The experiments were video and audio taped, transcribed and coded into a custom developed coding scheme. The results of the analysed coded data and observations of the videotapes provided evidence that there were noticeable differences between the three categories. There was more design communication and less communication control in the CMCD-b category compared to the FTF and CMCD-a categories. Verbal communication became shorter and straight to the point in CMCD-b as opposed to spontaneous non-stop chat in the other two categories. Moreover in CMCD-b the subjects were observed to be more reflective as well as choosing and re-examining their words to explain ideas to their partners. At times they were seen scrolling back through the text of the conversation in order to re-analyse or interpret the design ideas at hand. This was impossible in FTF and CMCD-a sessions, since the subjects were more spontaneous and audio representations were lost as soon as they were uttered. Also the video channel in the CMCD-a category was ignored and hardly used except for the first few minutes of the experiments, for a brief exchange of light humour on the appearance of each subject. The results obtained from analysing the experiments helped us conclude that different communication channels produce different collaborative environments. The three categories of communication for architectural collaboration explored in our experiments are indicative of the alternatives available to architects now. What is not clear to architects is why they would choose one category over another. We propose that each category has its own strengths and difficulties for architectural collaboration, and therefore should be selected on the basis of the type of communication considered to be most effective for the stage and tasks of the design project.

summary	The Department of Real Estate and Project Management (BMVB) of the Faculty of Architecture at the Delft University of Technology has been working closely with Professor Spiro N. Pollalis of Harvard University, Graduate School of Design in Cambridge, USA since 1991. His case-based interactive seminars about the management of the design & construction process have been highly appreciated by many generations of students. In Spring 2000, Pollalis suggested to extend the scope of his involvement by introducing a remote teaching component, the subject of his research in the last few years. As Information and Communication Technology (ICT) in the Design and Construction Industry is part of his lectures, it was appropriate to provide the students with a first hand experience on the subject. In the following experiment, the teacher would remain in his office at Harvard while the interactive work and discussion sessions with 130 students in a full lecture room would take place in Delft as planned. The consequences this experiment has had for the course, for the techniques and facilities used, how teachers and students experienced these, and which conclusions and recommendations can be made, are the topics of this paper.

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	A Core Object Model for Architectural Design
source	Katholieke Universiteit Leuven
summary	A core object model apt to describe architectural objects and their functionality is one of the keystones to an integrated digital design environment for architecture. The object model presented in this thesis is based on a conceptual framework for computer aided architectural design (CAAD) and aims to assist the architect designer right from the early stages in the design process. For its development the object-oriented analysis method MERODE (Model-based Existence-dependency Relationship Object-oriented Development) is used. After a survey on the role of computers in the architectural design process and on particular Product Modelling initiatives, the model is elaborated in two phases: the enterprise-modelling phase and the higher functionality-modelling phase. Actual design cases and test implementations help to establish the conceptual model and illustrate its concepts. The appendices provide a detailed description of both the object model and one of the case studies. The architect’s point of view and the specific nature of the architectural design process are the basic considerations, thus leading to a unique model that hopes to make a valuable contribution to the research area of integrated design environments.

title	In Case of Architectural Design. Critique and Praise of Case-Based Design in Architecture
source	Dissertation - Doct. Toegepaste wetenschappen, KU Leuven, Fac. Toegepaste wetenschappen, Dep. architectuur, stedebouw en ruimtelijke ordening (ISBN 90-5682-248-9)
summary	Architects are said to learn design by experience. Learning design by experience is the essence of Case-Based Design (CBD), a sub-domain of Artificial Intelligence. Part I critically explores the CBD approach from an architectural point of view, tracing its origins in the Theory of Dynamic Memory and highlighting its potential for architectural design. Seven CBD systems are analysed, experienced architects and design teachers are interviewed, and an experiment is carried out to examine how cases affect the design performance of architecture students. The results of this exploration show that despite its sound view on how architects acquire (design) knowledge, CBD is limited in important respects: it reduces architectural design to problem solving, is difficult to implement and has to contend with prejudices among the target group. With a view to stretching these limits, part II covers the design, implementation and evaluation of DYNAMO (Dynamic Architectural Memory On-line). This Web-based design tool tailors the CBD approach to the complexity of architectural design by effecting three transformations: extending the concern with design products towards design processes, turning static case bases into dynamic memories and upgrading users from passive case consumers to active case-based designers.
