title Using Higher Level Programming in Interdisciplinary teams as a means of training for Concurrent Engineering
doi https://doi.org/10.52842/conf.ecaade.2002.014
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. 14-19
summary The paper explains a didactical method for training students that has been run three times to date. The premise of the course is to combine students from different faculties into interdisciplinary teams. These teams then have a complex problem to resolve within an extremely short time span. In light of recent works from Joy and Kurzweil, the theme Robotics was chosen as an exercise that is timely, interesting and related, but not central to the studies of the various faculties. In groups of 3 to 5, students from faculties of architecture, computer science and mechanical engineering are entrusted to design, build and program a robot which must successfully execute a prescribed set of actions in a competitive atmosphere. The entire course lasts ten days and culminates with the competitive evaluation. The robots must navigate a labyrinth, communicate with on another and be able to cover longer distances with some speed. In order to simplify the resources available to the students, the Lego Mindstorms Robotic syshed 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).ural presentations in the medium of computer animation. These new forms of expression of design thoughts and ideas go beyond mere model making, and move more towards scenemaking and storytelling. The latter represents new methods of expression within computational environments for architects and designers.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 philosg and programming a winning robot. These differences became apparent early in the sessions and each group had to find ways to communicate their ideas and to collectively develop them by building on the strengths of each team member.

summary One of the problems facing students of architecture and those teaching of architecture is that the body of information which needs to be bourne in mind when designing is continually increasing. One area where there has been a rapid recent growth in interest and consequent legislation is in environmental or "green" matters. As an example recent legislation has been introduced in an effort to standardise the procedures for assessing building, and in particular their energy consumption. This paper reports on the development of a Hypermedia based tool to aid the process of the Environmental design of buildings with the objective of producing a computer-based aid which encourages understanding and innovation rather than leading the. user through a mechanical process of form filling. We conclude with comments on the effectiveness of the tool as a design aid and propose future developments for the work on computer-based Environmental Assessment.

title Graphical interfacing to a conceptual model for estimating the cost of residential construction
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary This paper presents a method for determining elemental square foot costs and cost significance for residential construction. Using AutoCAD's icon menu and dialogue box' facilities, a non-expert may graphically select (i) residential configuration; (ii) construction quality level; (iii) geographical location; (iv) square foot area; and finally, (v) add-ons, e.g. porches and decks, basement, heating and cooling equipment, garages and carports etc. in order to determine on-site builder's costs. Subsequent AutoLisp routines facilitate data transfer to a Lotus 1-2-3 spreadsheet where an elemental cost breakdown for the project may be determined. Finally, using Lotus 1-2-3 macros, computed data is transferred back to AutoCAD, where all cost significant items are graphically highlighted.

title Spatial Perception in Virtual Environments : Evaluating an Architectural Application
source University of Washington
summary Over the last several years, professionals from many different fields have come to the Human Interface Technology Laboratory (H.I.T.L) to discover and learn about virtual environments. In general, they are impressed by their experiences and express the tremendous potential the tool has in their respective fields. But the potentials are always projected far in the future, and the tool remains just a concept. This is justifiable because the quality of the visual experience is so much less than what people are used to seeing; high definition television, breathtaking special cinematographic effects and photorealistic computer renderings. Instead, the models in virtual environments are very simple looking; they are made of small spaces, filled with simple or abstract looking objects of little color distinctions as seen through displays of noticeably low resolution and at an update rate which leaves much to be desired. Clearly, for most applications, the requirements of precision have not been met yet with virtual interfaces as they exist today. However, there are a few domains where the relatively low level of the technology could be perfectly appropriate. In general, these are applications which require that the information be presented in symbolic or representational form. Having studied architecture, I knew that there are moments during the early part of the design process when conceptual decisions are made which require precisely the simple and representative nature available in existing virtual environments. This was a marvelous discovery for me because I had found a viable use for virtual environments which could be immediately beneficial to architecture, my shared area of interest. It would be further beneficial to architecture in that the virtual interface equipment I would be evaluating at the H.I.T.L. happens to be relatively less expensive and more practical than other configurations such as the "Walkthrough" at the University of North Carolina. The set-up at the H.I.T.L. could be easily introduced into architectural firms because it takes up very little physical room (150 square feet) and it does not require expensive and space taking hardware devices (such as the treadmill device for simulating walking). Now that the potential for using virtual environments in this architectural application is clear, it becomes important to verify that this tool succeeds in accurately representing space as intended. The purpose of this study is to verify that the perception of spaces is the same, in both simulated and real environment. It is hoped that the findings of this study will guide and accelerate the process by which the technology makes its way into the field of architecture.

title Creating the Electronic Design Studio: Development of a Heterogeneous Networked Environment at Harvard's Graduate School of Design
doi https://doi.org/10.52842/conf.ecaade.1992.225
source CAAD Instruction: The New Teaching of an Architect? [eCAADe Conference Proceedings] Barcelona (Spain) 12-14 November 1992, pp. 225-240
summary The migration of design education to reliance on computer-based techniques requires new ways of thinking about environments which can effectively support a diverse set of activities. Both from a spatial standpoint and a computing resource standpoint, design studios must be inevitably reconfigured to support new tools and reflect new ways of communicating. At Harvard's GSD, a commitment to incorporating computer literacy as a fundamental component of design education enables us to confront these issues through the implementation of a heterogeneous network imbedded in an electronic design environment. This evolving prototype of a new design studio, its development and its potential, will be the subject of this paper. A new style design environment is built upon an understanding of traditional techniques, and layered with an awareness of new tools and methods. Initially we borrow from existing metaphors which govern our interpretation of the way designers work. Next we seek to extend our thinking to include allied or related metaphors such as the library metaphor which informs collections of software and data, or the laboratory metaphor which informs workspace groupings, or the transportation metaphor which informs computer-based communications such as electronic mail or bulletin boards, or the utility services metaphor which informs the provision of network services and equipment. Our evaluation of this environment is based on direct feedback from its users, both faculty and students, and on subjective observation of the qualitative changes in communication which occur between and among these groups and individuals. Ultimately, the network must be judged as a framework for learning and evaluation, and its success depends both on its ability to absorb our existing metaphors for the process of design, and to prefigure the emerging metaphors to be envisioned in the future.

summary The development planning of the full-scale laboratory at the Vienna University of Technology was already presented to the third E.F.A. Conference in Lund (1990). Exchange of experience has greatly encouraged us to take all measures necessary for an immediate provisional operation. Working experience was of considerable significance regarding reconstruction work having repeatedly been postponed ever since 1988. This paper deals with the Vienna full-scale laboratory in its ultimate form and all the equipment designed therefore. Summarizingly, the further measures for operation are being considered.

title Interactions between Environmental Design and Human Factors Specialists ENVIRONMENTAL DESIGN: Panel
source Proceedings of the Human Factors Society 36th Annual Meeting 1992 v.1 pp. 575-577
summary Most of the interactions between human factors specialists, such as ergonomists, and environmental specialists such as facility planners and architects tend to be task specific and do not follow any accepted process. Consequently, the success of such interactions are usually a function of serendipity rather than informed expectation. It is anticipated that by gathering such specialists in an open discussion, relevant issues may be addressed and successful interaction procedures introduced and discussed. Such a forum is desirable for developing an understanding of the differences, educational and operational, between environmental design specialists, and human factors specialists, as well as for exploring the ways their communications can be enhanced. It is anticipated that by sharing their experiences with the attendees, the presenters will identify relevant on-going knowledge transfer activities, and also introduce and discuss practical problem-solving and communication methods that can be used with assurance by the attendees themselves when faced with similar problems in the future. This panel will focus on issues that arrive out of situations where human factors specialists and environmental design specialists are joined together in project development. The specialties represented include architecture, facility planning, environmental psychology, ergonomic research, industrial design and engineering, and equipment and furniture design and manufacturing.

title FULL-SCALE EXPERIMENT ON KITCHEN FUNCTION IN HANOI
source Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part A, pp. 19-30
summary This study is a part of a licentiate thesis on "Functional kitchen for the Vietnamese cooking way"at the Department of Architecture and Development studies, Lund University. The issues it is dealing with are: (1) Inadequacy of kitchen design in the apartment buildings in Hanoi, where the kitchen is often designed as a mere cooking place - other parts of the food making process are not given any attention. (2) Lack of standard dimensional and planning criteria for functional kitchen which can serve as bases for kitchen design. // The thesis aims at finding out indicators on functional spatial requirements for kitchen, which can serve as guide-line for designing functional kitchen for Hanoi. One of the main propositions in the thesis is that functional kitchens for Hanoi should be organised to permit the culinary activities done according to the Vietnamese urban culinary practice. This is based on the concept that the culinary activity is an expression Of culture, thus the practice of preparing meal in the present context of the urban households in Hanoi has an established pattern, method which demand a suitable area and arrangement in the kitchen. This pattern and cooking method should make up the functional requirement for kitchen in Hanoi, and be taken in to account if functional kitchen designing is to be achieved. In the context of the space-limited apartment building of Hanoi, special focus is given to find out indicators on the minimum functional spatial requirements of the kitchen works.

title A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

title Constraints for Generating Building Envelope Design Alternatives
source New York: John Wiley & Sons, 1992. pp. 145-155 : charts. includes bibliography
summary The building envelope design process involves selecting materials and constructional types for envelope components. Many different materials need to be combined together for wall and roof assemblies to meet the various performance requirements such as thermal efficiency, cost, acoustic and fire resistances. The number of performance attributes to be considered in the design process is large. Lack of information, time limitations and the large number of feasible design alternatives generally force the designer to rely on past experience and practical judgement to make rapid design decisions. Current work at the Centre for Buildings Studies focuses on the development of knowledge-based synthesis and evaluation techniques for reducing the problems of information handling and decision making in building envelope design. The generation of design alternatives is viewed as a search process that identifies feasible combinations of building envelope components satisfying a set of performance requirements, material compatibility, practicality of design, etc. This paper discusses knowledge acquisition and representation issues involved in the definition of constraints to guide the generation of feasible combinations of envelope components

summary In this paper the authors describe the role of performance evaluation in the Integrated Software Environment for Building Design and Construction Planning (IBDE), which is a testbed for examining integration issues in the same domain. Various processes in IBDE deal with the spatial configuration, structural design, and construction planning of high-rise office buildings. Performance evaluations occur within these processes based on different representation schemes and control mechanisms for the handling of performance knowledge. Within this multiprocess environment, opportunities also exist for performance evaluation across disciplines through design critics

title SEED: A Software Environment to Support the Early Phases in Building Design
source Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

summary The work described here is aimed at contributing towards the debate and development relating to the construction of interfaces to explore buildings and their environs through virtual worlds. We describe a particular hardware and software configuration which is derived by the use of low cost games software to create the Virtual Environment. The Physical Interface responds to the work of other researchers, in this area, in particular Shaw (1994) and Vasquez de Velasco & Trigo (1997). Virtual Evironments might have the potential to be "a magical window into other worlds, from molecules to minds" (Rheingold, 1992), but what is the nature of that window? Currently it is often a translucent opening which gives a hazy and distorted (disembodied) view. And many versions of such openings are relatively expensive. We consider ways towards clearing the haze without too much expense, adapting techniques proposed by developers of low cost virtual reality systems (Hollands, 1995) for use in an architectural setting.

title A functional approach to realizing decision support systems in technical regulation management for design and construction
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary Technical building standards defining the quality of buildings, building products, building materials and building processes aim to provide acceptable levels of safety, health, usefulness and energy consumption. However, the logical consistency between these goals and the set of regulations produced to achieve them is often hard to identify. Not only the large quantities of highly complex and frequently changing building regulations to be met, but also the variety of user demands and the steadily increasing technical information on (new) materials, products and buildings have produced a very complex set of knowledge and data that should be taken into account when handling technical building regulations. Integrating knowledge technology and database technology is an important step towards managing the complexity of technical regulations. Generally, two strategies can be followed to integrate knowledge and database technology. The main emphasis of the first strategy is on transferring data structures and processing techniques from one field of research to another. The second approach is concerned exclusively with the semantic structure of what is contained in the data-based or knowledge-based system. The aim of this paper is to show that the second or knowledge-level approach, in particular the theory of functional classifications, is more fundamental and more fruitful. It permits a goal-directed rationalized strategy towards analysis, use and application of regulations. Therefore, it enables the reconstruction of (deep) models of regulations, objects and of users accounting for the flexibility and dynamics that are responsible for the complexity of technical regulations. Finally, at the systems level, the theory supports an effective development of a new class of rational Decision Support Systems (DSS), which should reduce the complexity of technical regulations and restore the logical consistency between the goals of technical regulations and the technical regulations themselves.

title A Preliminary to Development of Expert Systems for Total Design of Entire Buildings
source New York: John Wiley & Sons, 1992. pp. 215-237 : tables. includes bibliography
summary This paper has two primary objectives. The first is to represent the practicability of making the design of entire buildings a conscious, craftsman-like, activity conducted in the clear, without the mystery that tends, because of designers' usual 'black box' methods, to surround it. To this end, a design strategy and some tactics for resolving decisions at critical stages in the design process, which the authors have described elsewhere, are recapitulated to show how total design of buildings can be pursued in a generic manner. This done, the way is opened for the second objective: to make the large and important field of work that is building design amenable to computerization. The form that pursuit of this second objective is taking is being influenced greatly by growing interest in expert systems, which for everyday professional building design appears a more useful development than previous CAD emphases on drafting and graphics. Application of the authors' design methods to a series of expert systems for the total design of entire buildings is therefore indicated. For such a vast project--the formulation of bases for design assistance and expert systems that can be integrated and used as a generic method for the total design of entire buildings, so that the results are more certain and successful than the outcome of the generality of present-day building design--the most that can be attempted within the limits of a single paper is a set of examples of some of the stages in the process. Nevertheless, since the design method described begins at the 'large end' of the process, where the most consequential decisions are made, it is hoped that the major thrusts and the essential CAD activities will be evident. All design is substantially iterative, and provided that the major iterations are intelligible, there should be no need for this demonstration to labor over the lesser ones

title Neural Network Simulation as a Computer- Aided design Tool For Predicting Wayfinding Performance
source New York: John Wiley & Sons, 1992. pp. 347-366 : ill. includes bibliography
summary Complex public facilities such as libraries, hospitals, and governmental buildings often present problems to users who must find their way through them. Research shows that difficulty in wayfinding has costs in terms of time, money, public safety, and stress that results from being lost. While a wide range of architectural research supports the notion that ease of wayfinding should be a criterion for good design, architects have no method for evaluating how well their building designs will support the wayfinding task. People store and retrieve information about the layout of the built environment in a knowledge representation known as the cognitive map. People depend on the information stored in the cognitive map to find their way through buildings. Although there are numerous simulations of the cognitive map, the mechanisms of these models are not constrained by what is known about the neurophysiology of the brain. Rather, these models incorporate search mechanisms that act on semantically encoded information about the environment. In this paper the author describes the evaluation and application of an artificial neural network simulation of the cognitive map as a means of predicting wayfinding behavior in buildings. This simulation is called NAPS-PC (Network Activity Processing Simulator--PC version). This physiologically plausible model represents knowledge about the layout of the environment through a network of inter-connected processing elements. The performance of NAPS-PC was evaluated against actual human wayfinding performance. The study found that the simulation generated behavior that matched the performance of human participants. After the validation, NAPS-PC was modified so that it could read environmental information directly from AutoCAD (a popular micro-computer-based CAD software package) drawing files, and perform 'wayfinding' tasks based on that environmental information. This prototype tool, called AutoNet, is conceptualized as a means of allowing designers to predict the wayfinding performance of users in a building before it is actually built

title Ratios for cost control
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary The design of buildings takes place in phases representing a development from rough to precision planning. Estimates are made in order to test whether the result is still within the budget set by the client or developer. In this way, the decisions taken during the design phase can be quantified and expressed in monetary terms. To prevent blaming the wrong person when an overrun is discovered, the cost control process has to be improved. For that purpose, two new procedures have been developed: (i) a new translation activity; and (ii) ratios by which quantities can be characterized. 'Translation is the opposite of estimation. A monetary budget is converted -'translated' - into quantities, reflecting the desired quality of the building materials. The financial constraints of the client are thus converted into quantities - the building components used by the designers. Characteristic quantity figures play an important role in this activity. In working out an estimate, the form factor (i.e., the ratio between two characteristic values of a building component) has to be determined. The unit cost is then tested against that ratio. The introduction of the 'translation' activity and the use of characteristic quantity figures and form factors enhance existing estimation methods. By implementing these procedures, cost control becomes considerably more reliable.
