title Models of Design Requirement
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Case studies show that significant proportions of design errors and failures are linked to poor requirement specification during both early stages of design and as changes occur. Computational requirements engineering as a front-end to design iterations is a promising area addressing theseproblems. In other design disciplines, such as in software engineering, requirement engineering has given significant product improvements. In this paper, we present a state-space representation of requirement models for architectural design. The purpose of requirement modeling in design is tocreate a process by which requirements can be converted into working design solutions through frontend validation. We suggest three models of requirement specification, co-evolutionary [CoM], multiple domain [MDM] and single domain [SDM] models, that can facilitate this effort. Taken together all three models provide a full set of logical permutations of requirement-solution “worlds” and “operations.” We compare each model against the others in terms of facilitating change management and computability.

title The Potential of Computer Modeling Software to Support a Consideration of Building Materials in Architectural Design Education
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 440-447

summary Most CAAD software in use for architectural education relies heavily on abstract geometry manipulation to create architectural form. Building materials are usually applied as finishing textures to complement the visual effect of the geometry. This paper attempts to investigate the limitations of commonly used CAAD software in terms of encouraging an intuitive thinking about the physical characteristics of building materials in the design studio environment. A case study involving 90 students is presented. The possibility of developing software that uses geometrical abstractions of different materials as the basis for modeling architectural form in the design studio is introduced.

title OBJECT-ORIENTED DATA MODELING AND WAREHOUSING TO SUPPORT URBAN DESIGN
source Ph.D. Dissertation, School of Architecture, Carnegie Mellon University
summary All over the world, local authorities are moving towards managing and storing urban data in digital form. But the data storage devices used are heterogeneous and typically include relational database management systems (DBMS), GIS and CAD files. As a result, data are present in different locations on different platforms and under different schemas. This poses a problem for software applications meant to support decision-making in urban design that require input from more than one data source. This dissertation demonstrates how data warehousing—combined with object-oriented data modeling—is able to provide a general solution for this problem. Data warehousing is a technique initially developed for business applications, but is equally useful for urban design: The data warehouse constitutes a communication layer between the urban design applications and data sources. It makes the data available through a unified interface that hides the sources themselves and represents that data in terms of a general-purpose, preferably object-oriented, model. The dissertation also describes an implementation prototype of the data model and the data warehouse. The test case of this research is the city of Makkah in Saudi Arabia, which faces significant urban design and planning issues in connection with the pilgrimage (Hajj) that brings millions of visitors to the city every year.

summary The first generations of computer aided design systems were largely characterized by geometrical modeling software that could, in some applications, generate physical output in the form of computer aided manufacturing. More recently the technology has expanded to include a variety of ways to reverse direction, such that physical objects are captured and translated into computer graphics geometrical models. Laser surveying methods that produce point clouds are among the newer technologies that make this possible. The interpretation of the point clouds and translation of them into a computer graphics three-dimensional model can be subject to various mediation processes. This paper reports on a translation environment that interprets the point clouds so as to not just replicate the physical world, but rather encapsulates it towards the refinement and realization of geometry design objectives. A case study of Fountains Abbey, a Cistercian Abbey in the United Kingdom, serves as the basis for experimentation and control of surface geometry.

summary The project IDEA+ aims to develop an “Integrated Design Environment for Architecture”. Its goal is providing a tool for the designer-architect that can be of assistance in the early-design phases. It should provide the possibility to perform tests (like heat or cost calculations) and simple simulations in the different (early) design phases, without the need for a fully detailed design or remodeling in a different application. The test for daylighting is already in development (Geebelen, to be published). The conceptual foundation for this design environment has been laid out in a scheme in which different design phases and scales are defined, together with appropriate tests at the different levels (Neuckermans, 1992). It is a translation of the “designerly” way of thinking of the architect (Cross, 1982). This conceptual model has been translated into a “Core Object Model” (Hendricx, 2000), which defines a structured object model to describe the necessary building model. These developments form the theoretical basis for the implementation of IDEA+ (both the data structure & prototype software), which is currently in progress. The research project addresses some issues, which are at the forefront of the architect’s interest while designing with CAAD. These are treated from the point of view of a practicing architect.

title Evaluating the Use of a Web-Based Collaborative Interactive Digital Model (CollABITA) in Supporting the Urban Design Approval Process1
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, III.1-III.15
summary This research, after analyzing the Urban Development Approval Process in its functionalities and methodologies, is showing the key points at which the process might be supported by new computer technologies, and it establishes a web-based Collaborative Interactive Digital Model (CollABITA Model) that relates and facilitates the graphical representation of the urban design process with some elements of the methodological approach. The CollABITA Model will dramatically facilitate the idea of broadening public participation, and indirectly by this, also collaboration. This new web-based support tool, is focusing on how new Informative Computer Technologies can be used in order to have a more co-operative design process. By utilizing the enormous potential of Internet for informing the process, and software for visualizing its products, the Model will provide an effective support, which will be able to deliver information in various forms to the Designers, Developers, Decision Makers, Agencies and the final user (the Citizens). The Model is concerned with the big challenge of supporting the urban design approval process itself, by exploring different kind of visualizations and communication tools, rather than producing a guide for carrying out the design. CollABITA Model is based on the existent framework structure of the extranet tool already available. Then, more then those, CollABITA Model will try to solve, by adding technical and collaborative functionalities, those issues that are characteristics in the urban design process and that are not jet solved by using one of the software .

title Modeling and rendering virtual architecture by using fisheye-panorama-based images and lightings in HDR-quality
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 569-571
doi https://doi.org/10.52842/conf.ecaade.2002.569
summary We use digitally made spherical panoramas as background for vr-visualisation in architectural sceneries instead of stitched photographs (fisheye-based or serical-mirrorbased). For this reason we had the idea to develop the first fisheye-based digital-scanning panorama-camera together with the manufacturer Spheron. The ultimate step in reaching optimal quality not only as a background but also as a source of lighting the background-image is taken as a HDR-image. The high-dynamic- range-technology was developed by the Californian scientist Paul Devebec. High dynamic photographs contain a broader range of information between the very bright zones down to the very dark zones - a lot more than “normal” photographs (digital and analogue), which are named LDR (low dynamic range in comparison to HDR). Some software-products in the field of cad-visualisation in virtual and augmented reality already enable the use of HDR-images and open a new field of controlling daylight and artificial light simulations with photographed backgrounds instaed of synthetic ones. The combination of digitally produced (scanned) sperical images together with the use of HDR open a wide range of new implementation in the field of architecture, especially in combining synthetic elements in existing buildings, e.g. new interior elements in an existing historical museum).

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 The Virtual Campus: A new place for (lifelong) learning?
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 472-477

summary 472 eCAADe 20 [design e-ducation] Modeling Real and Virtual Worlds Session 13 In the early spring of 2001 a collection of German universities founded a virtual faculty of architecture, which was named „Liquid Campus“. Current thinking about future forms of education in the field of architecture combined with over 4 years of experience with net-based design studios, led to questions about the future of existing universities, their buildings and their use. This problem was put to 43 students in the form of a design exercise to create a place for a virtual university. In the current situation, in which the administration of knowledge is more and more located on the internet, and even the so-called meeting places themselves can be virtualised through the help of video-conference-software, the exercise was to design a virtual campus in the framework and to carry out this design work in a simulation of distributed practice. Initial criticism of the project came from the students in that exemplary working methods were not described, but left for the students to discover on their own. The creation of a concept for the Liquid Campus meant that the participants had to imagine working in a world without the face to face contacts that form the basis (at present) of personal interaction. Additionally, the assignment to create or design possible links between the real and the virtual was not an easy task for students who normally design and plan real physical buildings. Even the tutors had difficulties in producing focused constructive criticism about a virtual campus; in effect the virtualisation of the university leads to a distinctive blurring of its boundaries. The project was conducted using the pedagogical framework of the netzentwurf.de; a relatively well established Internet based communication platform. This means that the studio was organised in the „traditional“ structure consisting of an initial 3 day workshop, a face to face midterm review, and a collective final review, held 3,5 months later in the Museum of Communication in Frankfurt am Main, Germany. In teams of 3 (with each student from a different university and a tutor located at a fourth) the students worked over the Internet to produce collaborative design solutions. The groups ended up with designs that spanned a range of solutions between real and virtual architecture. Examples of the student’s work (which is all available online) as well as their working methods are described. It must be said that the energy invested in the studio by the organisers of the virtual campus (as well as the students who took part) was considerably higher than in normal design studios and the paper seeks to look critically at the effort in relation to the outcomes achieved. The range and depth of the student’s work was surprising to many in the project, especially considering the initial hurdles (both social and technological) that had to overcome. The self-referential nature of the theme, the method and the working environment encouraged the students to take a more philosophical approach to the design problem. The paper explores the implications of the student’s conclusions on the nature of the university in general and draws conclusions specific to architectural education and the role of architecture in this process.

summary The programming languages typically offered by CAD systems for third-party application developerswere procedural or functional. A major shift is currently occurring in that new versions of commercialCAD software will support object-oriented programming languages for application development.Developers who wish to take advantage of this new kind of environment must undergo a considerablecognitive “retooling” and adopt new software engineering strategies. We describe a graduate coursethat aims at introducing students to effective object-oriented development strategies, especially usecase-driven development and the tools provided by the Unified Modeling Language (UML). Studentsgained experience with these tools by forming, together with the instructors, a single development teamwriting an application on top of MicroStation/J using JMDL as programming language. The paperdescribes the instructors’ experience with this approach.

title An Information-based Framework for Composites Design
source Drexel University
summary The heterogeneity of composites determines that composite materials can be engineered to better satisfy a specific design requirement. The main problems that have hindered the application of composites are the need for the material and manufacturing design to be conducted simultaneously, the involvement of a large number of design factors, the difficulty in the characterization of composites, and the inherent repetition of the design process. Considering these problems, this thesis presents an information-based framework for composites design. This research consists of four main aspects: (1) The development of a heterogeneous CAD modeling algorithm and an integrated CAD/CAE method, and their application in a unit cell-based characterization of composite materials with a complex fiber form; (2)The development of a unit cell database for improving the material and manufacturing process design, which covers the design of its database model and the access strategies based on the logic architecture of unit cells and the relationships among elements of unit cells and with the environments; (3)The design of an Information-Based Design Support System (IBDSS) to support the composites design by using the unit cell database, in which the blackboard framework is adopted for the system to organize various computer techniques for different design stages, and to support the design iterating to satisfactory ones incrementally and efficiently, and the data structure of the blackboard, the algorithm to control design iterations, and design procedures for every stage are studied; and (4) The introduction of a ranking-based unit cell evaluation methodology and effective ranking factors for facilitating and improving the composite design process. The approach improves the efficiency of composites design by automating design iterations, supporting composite characterization, alleviating the cost of composite material and manufacturing method design, and assisting in tailored material selection. Case studies are presented to show how the IBDSS is applied to support composites design.

source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary An Urban and Regional Planning System based on a geographical information system was developed using four sub-systems consisting of a digital map system, a database system, an analysis and forecast system and a planning system. In this case ARCVIEW GIS software was used as a development tool. The digital map system is formulated by the planar orthogonal coordinate system. The data is converted from digital maps issued by the Geographical Survey Institute of Japan (GSI). The database system has layers of data sets, which consist of statistical data, attribute data of geographical points and characteristics of natural features and the built environment. Several sets of principal census data havebeen converted to mesh data. These kinds of data sets are also utilized to this system. LANDSAT TM data is converted into vector data and linked to the same coordinate system. The analysis and forecast system consists of statistical or mathematical analysis, forecasts and visual presentations of the results. The planning system consists of some planning models and reviewing techniques to evaluate alternatives. As an example, this paper examines the relationship between land use and the temperatureon the ground level in built-up areas.

title Definition of a Method of Limits of the Simplification of a Hall Model in a CAD System to Diminish Falsification of Acoustic Simulation Results

doi https://doi.org/10.52842/conf.ecaade.2005.695
summary During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

Some of the basic mechanics and theoretical concepts of fluid flowand wind pressure as well as their translation into design criteria for structural analysis and design arereviewed, followed by a discussion of a detailed Computational Fluid Dynamics (CFD) application casestudy for a simulated "3-second gust" hurricane force wind flow over a low rectangular building locatedin a coastal region of south Florida. The case study project models the wind flow behavior and pressuredistribution over the building structure when situated in three varying conditions within a single terrainexposure category. The simulations include three-dimensional modeling of the building type constructed(1) on-grade in a flat coastal area, (2) above grade with the building elevated on structural columns, and(3) on-grade downwind of an escarpment. The techniques and parameters for development of thesimulations are discussed and some preliminary interpretations of the results are evaluated bycomparing their predictions to existing experimental and analytical data, with special attention paid tothe numerical methods outlined in the American Society of Civil Engineers, Minimum Design Loads forBuildings and Other Structures, ASCE 7-98.

Some of the basic mechanics and theoretical concepts of fluid flow and wind pressure as well as their translation into design criteria for structural analysis and design are reviewed, followed by a discussion of a detailed Computational Fluid Dynamics (CFD) application case study for asimulated “3-second gust” hurricane force wind flow over a low rectangular building located in a coastal region of south Florida. The case study project models the wind flow behavior and pressure distribution over the building structure when situated in three varying conditions within a single terrain exposure category. The simulations include three-dimensional modeling of the building type constructed (1) on-grade in a flat coastal area, (2) above grade with the building elevated on structural columns, and (3) ongradedownwind of an escarpment. The techniques and parameters for development of the simulations are discussed and some preliminary interpretations of the results are evaluated by comparing their predictions to existing experimental and analytical data, with special attention paid to the numerical methods outlined in the American Society of Civil Engineers, Minimum Design Loads for Buildings and Other Structures, ASCE 7-98.

title Modeling Urban Spaces: GIS and CAD Compared
source Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 345-348

summary This research is producing digital cartographic models of the urban space of Rome, NY. Workingbetween two software packages for spatial visualization that are now ubiquitous in architecture (FormZ)and geography (ArcView), the project takes an interdisciplinary approach to understanding howavailable data sources and modes of visualization enable or discourage particular understandings ofurban space. The project is designed specifically to work within, and develop, a critique of theconstraints of the two software packages. Rather than encouraging a deceptively smooth integration ofwhat may be fundamentally incommensurable forms of knowledge, this project begins with the premisethat vocabularies and conceptions of space vary considerably in various disciplines, as do the modes ofvisualization that each has developed to represent, document, examine, and produce space.

summary This paper describes a project that has been on-going since 2000 and consists of the followingactivities:• specification of Digital Human Models (DHM) for the visualization of people seated in wheelchairs,• extension of commercial off the shelf (COTS) software to enable the development of dynamicvisualizations of ‘data that makes data’ , and• subsequent construction of digital visualizations that are useful to designers in the creation ofartifacts and environments for human use.We have developed a process of ‘data that makes data’ which allows the visualization of any potentialor hypothetical physical interface between a human and an environment or artifact.Preliminary validation is provided by comparison with findings of other researchers. This work clearlysuggests a need for design-oriented software that contains robust ‘dynamic’ digital human modelscapable of creating visualization for any arbitrary context.
