title	Climatic Factors in Regional Design: An Interactive Tool for Design Education
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 188-201

summary	This paper describes the development of an interactive computerized module developed as a digital resource for architectural design students that incorporates the premise of using architectural form as a primary environmental control system in a building. The first in a series of such modules, Climactic Factors in Regional Design illustrates the factors involved in regional design strategies. With the recognition that many design practices of the latter twentieth century are not environmentally sustainable, this module is to be used in a curriculum which recognizes that sustainable architecture begins by using architectural form as the primary environmental control system and the mechanical and electrical systems supplement that system not dominate it. With recent advances in recognizing sustainability issues, the country is now more willing to embrace environmental stewardship. The path to reduce environmental problems is through the integration of practices recognize architectural form as a primary environmental control system. As such, the latest generation of designers must view design comprehensively. If future building designers are to succeed, environmental control integration needs to be included pro-actively within the initial design rather than reactively appended to the end. Climatic Factors in Regional Design is designed to foster this paradigm shift and is divided into several topics and subtopic sections which include Introduction, Regional Design, Microclimate, Regional Guidelines, Design Strategies, Glossary, and Sample Examination. The module contains 260 screen displays and more than 250 illustrations, figures, and diagrams. Users can progress through the module in any sequence as their needs warrant. The module was developed using the academic version of Authorware Star by Macromedia.

summary	The Information System of Building Components -ISBC, consists of a set of activities to control the graphic data operation procedures of building plans and its storage in a data base. The system is specially prepared to be used by architects, engineers and cad operators who are dealing with a continuous flow of design problems, regarding the permanent adaptation and modification of office's layout in a great amount of buildings around the country. These constant changes bring out several types of architectural design problems that should be taken into consideration by the proposed system, particularly the reallocation of office furniture and the modification of building components. Therefore, the principal goal of the system is based on the inquiry and permanently updating of the data base composed by: furniture, technical equipment (computers and telecommunications networks), lights, air-conditioning, sanitary equipments and any other equipment that can be inventoried. The generation and operation of great amount of graphics and alphanumerical information bring out severe data inconsistency problems, particularly when graphic data is envolved. The task of "feeding" and modifying a data base produces errors that aren't easy to solve, even when specific consistency procedures are used. The ISBC provides the computer routines for the initial task of building up the required data base of each building, allowing to use an interactive algorithm among the digitized plans of each office and the data base of the enquiry system. An additional operation included in the system allows to compute the area of each section of the building in order to calculate several types of working spaces regarding ergonomical and functional performance specifications established by law regulations.

title	Conjoint Analysis and Virtual Reality - A Review
source	Timmermans (ed.), 4 Ih Design and Decision Support Systems in Architecture and Urban Planning Conference.
summary	This paper describes a review of an ongoing research project which aims to develop a conjoint analysis and virtual reality (CA&VR) system as part of a design information system in virtual reality. The research project aims to develop a design system that can be used for interactive design and evaluation of design alternatives. A virtual environment model and dynamic virtual objects representing the different design aspects of interest can present a design. The different design aspects are called attributes. Each attribute level is a different state of the concerned virtual object. In the case of a virtual walk through a building design, the system can be viewed as a visual simulation of the environment. The CA&VR system has the potential advantage that individuals' preferences can be measured in designed hypothetical choice situations. As part of the ongoing research project, principles underlying the CA&VR system will be illustrated by simple examples. The status of this research project, both in retrospect and in prospect will be described.

title	Structural Feel or Feelings for Structure? - Stirring Emotions through the Computer Interface in Behaviour Analysis of Building Structures
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 163-171
doi	https://doi.org/10.52842/conf.caadria.1998.163
summary	The use of computers in the analysis of architectural structures has at present become indispensable and fairly routine. Researchers & professionals in architecture and engineering have taken advantage of current computer technology to develop richer and more comprehensive interactive interfaces in systems designed to analyse structural behaviour. This paper discusses a research project which attempts to further enrich such computer interfaces by embodying emotion or mood (affective) components into them and assessing the effects of incorporating these into multimodal learning modules for students of architecture at the University of Hong Kong. Computer structural analysis is most often used to determine the final state of a structure after full loading, but can also be used very ably to depict the time-history behaviour of a structure. The time-dependent nature of this process of behaviour provides an excellent opportunity to incorporate emotion cues for added emphasis and reinforcement. Studying time-history behaviour of structures is a vital part of classroom learning in structures and this why such emotion cues can have significant impact in such an environment. This is in contrast to the confines of professional engineering practices where these cues may not be as useful or desirable because oftentimes intermediate time history data is bypassed as a blackbox and focus is placed primarily on bottomline analysis results. The paper will discuss the fundamental basis for the establishment of emotional cues in this project as well as it's implementation-which consists mainly of two parts. The first involves 'personifying' the structure by putting in place a structure monitoring system analogous to human vital signs. The second involves setting up a 'ladder' of emotion states (which vary from feelings of serenity to those of extreme anxiety) mapped to the various states of a structures stability or condition. The paper will further elaborate on how this is achieved through the use of percussion, musical motifs, and chord progression in resonance with relevant graphical animations. Initially in this project, emotion cues were used to reinforce two structural behaviour tutoring systems developed by this author (3D Catenary Stuctures module & Plastic Behaviour of Semi-rigid Steel Frames module). These modules were ideal for implementing these cues because both depicted nonlinear structural behaviour in a mainly time-history oriented presentation. A brief demonstration of the actual learning modules used in the project study will also be presented together with a discussion of the assessment of it's effectiveness in actual classroom teaching.

summary	This paper outlines a research project that explores the participation in, and perception of, advanced technologies in architectural professional practice through a sociotechnical lens and presents empirical research findings from an online survey distributed to employees in five large-scale architectural practices in Sydney, Australia. This argues that while the computational design paradigm might be well accepted, understood, and documented in academic research contexts, the extent and ways that computational design thinking and methods are put-into-practice has to date been less explored. In engineering and construction, technology adoption studies since the mid 1990s have measured information technology (IT) use (Howard et al. 1998; Samuelson and Björk 2013). In architecture, research has also focused on quantifying IT use (Cichocka 2017), as well as the examination of specific practices such as building information modelling (BIM) (Cardoso Llach 2017; Herr and Fischer 2017; Son et al. 2015). With the notable exceptions of Daniel Cardoso Llach (2015; 2017) and Yanni Loukissas (2012), few scholars have explored advanced technologies in architectural practice from a sociotechnical perspective. This paper argues that a sociotechnical lens can net valuable insights into advanced technology engagement to inform pedagogical approaches in architectural education as well as strategies for continuing professional development.

title	A methodological approach to object modelling in the architectural designprocess
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The paper describes a first prototype constructed in search for a central object model. It presents all possible data, concepts and operations concerning the architectural design process in the early phases.A central model of the process of design is essential: going from one design phase into another, the model describes geometrical shapes, abstract concepts like space and activity, concrete physical building elements and the basic operations all these entities undertake. Emphasis is put on combining all these different viewpoints, thus enabling the designer to use a broad range of design strategies. The aim is to help him and not steer or even hamper his creative process. Information necessary toassist the user of the system concerning energy calculation, stability checks etc can be extracted. By means of appropriate interfaces not only those tests built on top of the system but also existing software packages can make use of the model’s object structure. The implemented object model is one of the cornerstones of the IDEA+ project, aiming to provide an Integrated Design Environment for Architecture.

title	Prototype of an Interactive Case Library for Architectural Design
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Architects acquire an important part of their design knowledge from existing designs. Specific design projects from the past form an indispensable source of information and inspiration. Hence the idea todevelop a digital library of design cases that can be easily accessed during design. The paper describes a recently developed prototype of such a case library, intended to assist architecture students in the studio,yet with the potential of expansion into the office setting. When students enrol into a design project, they usually receive a reader with some relevant examples. At first sight, the digital case library only seems torepresent these examples into another medium, yet there are some important differences between both. Unlike the reader, the library has at its core an indexing-system which allows the easy retrieval of relevantinformation. By labelling projects with several features and making links between similar designs, the tool supports both directed search and browsing. A second difference is that the library is interactive. Studentsare not only able to consult interesting examples, but also to add other projects they consider relevant, to make links between them, to create extra indices etc. Finally, the tool allows to combine several media andto create links to external information sources.

title	A Computational Model for Problem-Decomposing Strategy

doi	https://doi.org/10.52842/conf.caadria.1998.415
summary	Conventional computational models such as Soar, Act, and Mental Models, solve problems by pattern matching. However, according to other cognitive psychology-related studies, the searching strategies employed by experts and novices in well-structured problems closely resemble each other. Restated, problem-decomposing strategies allow expert designers to perform more effectively than novices. In this study, we construct a rule-based floor-planning CAD system in Lisp to closely examine the relationship between problem-decomposing strategies and design behavior in computation. Execution results demonstrate that the larger the number of elements that the system considers implies more efficient problem-decomposing strategies.

title	Network-Based Dynamic Evaluation Process for Urban Landscapes

doi	https://doi.org/10.52842/conf.caadria.1998.213
summary	When designing large-scale projects that affect urban landscapes such as the construction of power stations, it is important for a designer, to be able to predict how the landscape will be changed and public opinion in regard to the design stage. In order to support the communication between the public and the designer in the design process, authors have proposed a Network-Based Dynamic Evaluation Process (NDEP) for urban landscapes with WEB. This process can achieve a consensus decision, by applying the interactive cycles of proposal and evaluation to the design process. In this paper the authors outlined the framework of the process, the evaluation method by AHP, and a case study of an experimental production system.

summary	3-D models and computer graphics with its visual characteristics enables easier understanding of various information. Up until now 3-D models and computer graphics has not been used for the analysis of city information due to its high cost and the need for special techniques. Currently, we have discovered new technology in hyper medium based on network technology and lower costs. This paper focuses on the construction of an interactive and visual 3-D city information system, aiming at the ‘idea processor’ for research and analysis of city planning and market research. We have discovered the requirements necessary for the City Information Visualizer system. Using this technology we will construct the prototype system of the 3-D City Information Visualizer. This system is based on the personal computer and the Client/Server system. The system is then applied to practical city analysis. This paper presents the prototype system and its evaluation in a real project.

title	An IT-based Strategy For Design Education: Knowledge Engineering
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 101-109
doi	https://doi.org/10.52842/conf.ecaade.1998.101
summary	University education is considered to be a "knowledge industry" in a knowledge society. In this paper we describe education as the knowledge transfer from one intelligent system to another, and draw upon the experience in Artificial Intelligence in order to apply it as an active knowledge acquisition strategy for the use of Human Intelligence. In current educational strategies, too often students are treated as passive recipients of knowledge unlike their counterparts (knowledge engineers) in Artificial Intelligence. In design education, we should be concerned with providing students the ability to extract the acquired knowledge from their teachers. In this paper, we put six hypotheses and prove each of them by discussing the methodology of Knowledge Acquisition to improve the process of design education. For an active learning strategy in Knowledge Acquisition, we turn to the wealth of experience made in Knowledge Engineering. In our analogy, we consider students to be Knowledge Engineers, designers to be Knowledge Based Systems, teachers to be the domain experts, and the learning process to equal the Knowledge Acquisition process in Expert System development. Thus, we suggest the use of Knowledge Engineering methods in the acquisition of design knowledge to build a knowledge base. A well-defined knowledge base represented in a Knowledge Based System can serve as a reasoning mechanism for the design actions that are unteachable in characteristics.

title	Remote File Sharing for Community-led Local Agenda 21 Sustainability with Internet, Intranets and VideoConferencing
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 116-122
doi	https://doi.org/10.52842/conf.ecaade.1998.116
summary	This paper considers new opportunities for ease of remote file sharing through the Internet, Intranets and VideoConferencing, as facilitating opportunities for informed consumer intervention and greater accountability of the design. A remote file sharing experiment, [through a VideoConference link], of a 3D CAD estate model, collaboratively developed with a local resident?s association, is discussed. A different example looks at use of the Internet route by a small practice in the North West, developing QuickTime and QuickTimeVirtual Reality files for remote distribution and collaboration. The value of the full building object-orientated, data based model, [incorporating all related data and decisions from conception, client participation, project and facilities and life time management], is seen to offer an excellent vehicle for illustrating, negotiating and recording decisions. New international CAD standards for remote transfer and file sharing bring ease of use into the arena. Associated peripherals for remote file sharing through both Internet and video/teleconferencing, point to a transformation in the way we collaborate in the future. Signs from a broad band of businesses indicate that there is a clear understanding [in some circles] of the potential and the specific orientation of Web targeting, people-networking and dialogue. The key change is that those who understand this, build on the particular opportunity to contact and relate with any community of interest and to develop dialogue in a deeper, closer manner. So, we can see a strange phenomenon that the remoteness can actually bring a closeness of a new kind, as communities explore common interests. The paper considers how this may be the key to involving thousands of residents in a well-recorded dialogue, so bringing improved opportunities for meeting European standards in public accountability and community involvement in the development of Local Agenda 21 sustainability strategies.

title	AutoPave: towards an automated paving system for asphalt pavement compaction operations
source	Automation in Construction 8 (2) (1998) pp. 165-180
summary	Asphalt pavement density from roller compaction is a crucial factor in ensuring satisfactory pavement performance. Proper and uniform compaction of the pavement mat is essential in achieving the desired final compacted density. There is a necessity to investigate existing pavement construction practices, and provide more cost-effective modifications to the current scenario. Automation of the paving operation can increase the efficiency and quality of the operation, lead to reductions in overall project costs and time, and enhance pavement life. A system can be developed through algorithmic planning and real-time guidance strategies, and the development of a semi-automated path-planning and real-time guidance system that aims towards automating the paving operation. This system accepts relevant paving project inputs, generates appropriate path plans for the compactor, performs a graphical visualization of the generated path plan, and offers real-time guidance capabilities using Global Positioning Systems (GPS) technology. This system, named AUTOPAVE (v1.0), was developed in Microsoft Visual Basic™ programming language and offers a user-friendly and interactive graphical interface. The proposed new system will incorporate state-of-the-art GPS technology to standardize paving operations that are more amenable to rigorous quality control, and can result in considerable reductions in cost and time involved in asphalt pavement construction projects. This system was tested on several actual paving projects, and many operational issues related to the functioning of the system were successfully overcome.

title	Criteria for an object oriented library system of high–level parametric CADelements
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The subject of this paper is the development of criteria and specifications for an object oriented library system of high–level parametric elements that have an integrated 2D and 3D representation. High–levelelements are virtual representations of architectural elements such as windows, doors, etc. High–level parametric elements need few components to be flexible and easily customizable. The generalization ofeach element by its characteristic parts results in a substantial reduction in the number of polygons that must be processed by the computer during the 3D transformation, graphically clean 3D images and low demandon user intervention. Gestalt theory emphasizes the importance of contour lines for the perception of an element. The “minimalist” symbolic representation will simplify contour lines that enhance perception. Theinherent flexibility and functionality of object oriented elements are augmented when the elements are rigorously developed as an object oriented library system, with classes and sub-classes of elements whichinherit characteristics of the parent–class. Attribute values of a parent–class give the user global control over all instances of that class and its sub–classes in the model’s database. The concepts which SystemsTheory uses for making an abstraction of reality are analogous to the concepts used in object oriented programming. This paper describes how Systems Theory is used as tool to develop high–level parametric elements as a functionally and computationally efficient library system.

summary	A robust, semi-automatic way is presented to create 3D polyhedral building models from computer-drawn floor plans, requiring minimal user interaction. The modelsadhere to a consistent solids representation and can be used for computer rendering, visualization in interactive walkthroughs, and in various simulation and analysisprograms. The output of our prototype program is directly compatible with the Berkeley WALKTHRU system and with the NIST CFAST fire simulator. A consistentmodel of a seven-storey building with more than 300 rooms has been generated in the time span of a few days from original AutoCAD floor plans drawn by architects.

title	Computational decision support and the building delivery process: a necessary dialogue
source	Automation in Construction 7 (2-3) (1998) pp. 205-211
summary	The current critical discourse of computational design support systems (particularly building performance modeling tools) focuses more often than not on the `endogenous' system problems, that is deficiencies in user communication, absence of integration, and the `black-box' character of the underlying computational routines. As a result of this mostly valid criticism, work has been initiated in various quarters to improve modeling-based decision support environments. This paper argues that parallel efforts are needed to address other factors that go beyond the immediate technical realm of tool-making and involve matters pertaining to issues of building design and construction process at large. The building delivery process has traditionally been regarded as a discrete and sequential set of activities. This state of affairs is the result of a historical evolution driven by many factors, one of which might be the necessity to organize the activities for the purpose of establishing a professional fee structure that is commensurate with the scope of work and level of accountability or responsibility. However, within the context of rapidly changing building technologies, production processes, and knowledge transfer mechanisms, the existing procedural framework no longer seems capable of meeting the increasingly complex demands associated with the creation of the built environment. While the technical capabilities of decision support tools are expanding, they still fall short of challenging the very logic of the often nonintegrated processes they are designated to support. It may be understandable that, as compared to tools, processes tend to be more resilient to structural changes because of their inherent communicative nature, evolved over time through general acceptance and consensus. This paper argues, however, that careful study of the necessary conditions under which significant structural changes in the building delivery process would evolve, can effectively inform the developmental strategies in computational design support toward anticipation and encouragement of such changes.

title	Building a Case-Based Design Assistant forWorkplace Environment Design
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	This paper reports on the early stages of development of a case-based design tool. The purpose of this tool, called the Workplace Environment Design Advisor (WEDA), is to support architects in the conceptual design of workplace environments. The objective of this system is to provide electronic storage, retrieval and the exploration of post-occupancy performance knowledge of workplace environments. The paper provides a description of the reasoning behind choosing a case-based approach and thesteps used to develop a prototype case-based system. This includes recent efforts to collect and structure real case data. This experience led to observations about issues such as case content (the availability and format of post-occupancy data) and retrieval strategies. The data collected for use in the system is based on a building-in-use study of the Centre ofBuilding Research’s office rooms located at the University of Eindhoven, the Netherlands.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.
