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	Playing with Design Intent: Integration of Physical and Urban Constraints in CAD
doi	https://doi.org/10.52842/conf.acadia.1998.118
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. 118-137
summary	Our work deals with the exploration of a universe of forms that satisfy some design intents. That is, we substitute a “generate and test” approach for a declarative approach in which an object is created from its properties. In this paper we present an original method that takes into account design intents relative to sunlight, visibility and urban regulation. First of all we study how current CAD tools have considered these properties until now. Our conclusion is that the classical design / simulation / analysis process does not suit design practices, especially in the early stages. We think that an improved CAD system should offer the architect the option of manipulating abstract information such as design intents. We define an intent as a conceptual expression of constraints having an influence on the project. For instance, a visual intent will be stated with no reference to vision geometry: “ from this place, I want to see the front of the new building”. We show how to represent each of these constraints with a 3D volume associated to some characteristics. If some solutions exist, we are sure that they are included in these volumes. For physical phenomena we compute the volume geometry using the principles of inverse simulation. In the case of urban regulation we apply deduction rules. Design intents are solved by means of geometrical entities that represent openings or obstructions in the project. Computing constraint volumes is a way of guiding the architect in his exploration of solutions. Constraint volumes are new spaces that can restore the link between form and phenomenon in a CAD tool. Our approach offers the designer the possibility of manipulating design intents.

title	Geometric Modeling intThe Simulation of Fire - Smoke Spread in Buildings
source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 438-445
summary	Since the performance simulation of buildings, such as fire/smoke spread, energy loss/gain, acoustics, etc. greatly rely on building geometry, the way the physical environment is modeled can substantially effect the reliability of the predictions made by such simulations. Most computer models that simulate fire and smoke spread in buildings limit the computer representation of the building to simpler geometries and define rooms as rectangular spaces or as spaces with uniform crossections. Such a definition does not account for the variety of building elements that can exist in a building such as large overhangs, half height walls, etc. Existing simulations are typically developed as mathematical models and use the principles of thermodynamics to represent the spread of the elements of fire through space over a given time period. For example, in zone models each room is defined as a two tier space with heat and smoke exchange between lower and upper tiers as the fire progresses. On the other hand, field models divide the space into small contiguous units where thermodynamic state of each unit is calculated as the simulated fire progresses. Dynamic processes such as fire and smoke spread must recognize both intangible (i.e. voids) and tangible (i.e. solids such as walls, balconies, ceiling, etc.) architectural entities. This paper explores the potential of solid modeling techniques in generating geometric definitions for both solid and void architectural entities that can interact With mathematical models of fire/smoke spread in buildings. The implications of cellular spatial partitioning techniques for zone or field models of fire/smoke spread are investigated, and the methods of creating cellular decomposftion models for architectural spaces as well as for spatial boundaries such as walls are explored. The size of each cellular partition, i.e. the resolution of the partition, and the material and heat transfer attributes of each cell were found to be very critical in modeling the spread fire through voids as well as through solids in a building.

title	Graphical Interface Design for Equipment Control in Unstructured Environments
source	University of Texas at Austin, Dept. of Civil Engineering
summary	This dissertation is concerned with graphical interfaces to improve equipment control in unstructured environments such as construction, demolition, mining, and facility/infrastructure maintenance. Initial evidence indicates that graphical representation of equipment and work environments would enhance equipment control by providing better spatial perception to the operator. Real-time simulation and task planning with graphical models can also ensure safe and reliable operation of equipment. In addition, graphical interfaces can assist the operator to plan, measure, and record work progress by integrating design or as-built CAD databases with graphical models of equipment and work environments. The use of graphical models for equipment control in unstructured environments, however, has limitations, because it is very difficult to generate exact graphical models in such a quickly changing environment. The main objectives of this study were to develop principles for design of, and to validate the usefulness of graphical interfaces for equipment control in unstructured environments. The design principles were derived based on general literature and case studies of the existing graphical control interface systems. The graphical control interface for a tele-operated clinker clearing robot was then designed and implemented based on the derived principles. The developed graphical interface was tested and evaluated, and the implementation was analyzed with respect to the derived principles. The quantitative test results of the graphical control interface for the tele-operated clinker clearing robot validated the usefulness of graphical interfaces for equipment control in unstructured environments. The design principles were also verified with the test results.

title	Applying Computational Fluid Dynamics to Architectural Design Development - Strategy and Implementation
doi	https://doi.org/10.52842/conf.caadria.1998.133
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. 133-142
summary	This paper presents the development process and preliminary results of several research projects that apply computational fluid dynamics (CFD) to architectural design. The CFD On-line Teaching project is developing a multimedia training course for architecture students to apply CFD simulation to their projects. Each lesson illus-trates basic principles regarding air flow in building design, and provides CFD sample files with pre-defined flow cells for students to test these concepts. The Chinese Temple project uses CFD simulation to study the wind resistance of a Tong Dynasty heavy timber structure, with particular attention to the roof form. Air flow information generated in the project includes the visual representation of the pressure distribution and velocity field on all slices through the temple, as well as particle tracks around and through the building. The Urban Housing Air Duct project focuses on air duct design for the China Experimental Urban Housing Scheme. The visual representation of the pressure distribution and velocity field in the ducts provides vital information for helping the China Housing Research Center improve the current 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	An analysis is made of the relation between the conceptualand paradigmatic level of GIS technologies and the new forms of plan, whichmake environment the center of attention. The intention is to study newcriteria for zoning able to give contextual representations of theterritorial, environmental and landscape aspects of the geographical space,and also to study new legislative principles, able to establish integratedrules for theprojecting of soil uses, the safeguarding and recovery ofenvironmental systems and the tutelage and boosting of the landscape. The experimentation of GIS (Geographical Information System)technologies aims at the construction of systems helping to make decisionsfor the control of the environmental and landscape aspects of theterritory. An analysis is made of the ways in which there are formulated thedescriptions of the various aspects of the environment: the conceptsthrough which knowledge is expressed, the languages used forrepresentations, the cognitive models adopted. GIS technologies have made it possible to represent in an explicitmanner the paradigms underlying the various models of knowledge.Specifically, the following cognitive models have been developed:- ecological models of nature- ecological models of human settlement- ecological models of inhabitants’ mental perceptions

title	Development of a Building System
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 universal principle of architecture can be defined as follows: “The architectural product is the synthesis of the different man-made physical environments that are formed by locating the series of building components in different ways”. Within this context; it is necessary to determine the principle of building assembly and the assembly of ‘material components’ in order to produce the building. The material components are the elements of sub systems (such as; structural, envelope, services, partitions, circulation, and finishing systems) which form the building system of an architectural product. Every building is an integrated product. Integration defines the relations of sub systems with the whole. Therefore, it is necessary to define the sub systems and their relations in realizing the architectural product. This paper presents the analysis principles of the sub-systems, relationship between the analyzed systems and components, integration principles and possibilities of them, and the future conditions.

source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 26-30
summary	This paper reports on the activities of CADET in the design studio environment and in a variety of community contexts with the objective of developing a strategy for teaching design within the context of design, art, architecture and engineering. It begins with an outline of earlier design projects, in a variety of traditional media and in CAAD at several levels within the Undergraduate programme at the University of Strathclyde together with community organisations. It then outlines a model with a number of strands that explore the principles of visual communication which are fundamental to both the development and communication of design ideas. The report will place these activities in the context of developments in education and the wider sphere of cultural heritage, which ultimately inform understanding and knowledge of our architectural and design heritage. It will highlight and explore some important ideas that inform our judgment of aesthetic forms and refer students to relevant texts and precedents in art, design, engineering and architecture.

title	Supporting information navigation in generative design systems
source	Camegie Mellon University, School of Architecture
summary	Generative design systems make it easier for designers to generate and explore design altematives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed to enable designers to access the information with ease. Such aids may improve the usability of generative design systems and encourage their use in architectural practice. This dissertation presents a comprehensive approach to support navigation in generative design systems. This approach takes account of studies related to human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. It contains a general model of design space, basic navigation operations, and principles for designing navigation support. The design space model describes how the space may grow and evolve along predictable dimensions. The basic operations facilitate navigation activities in this multi-dimensional design space. The design principles aim at guiding system developers in creating navigation utilities tailored to the needs of individual design systems. This approach is validated through prototype implementations and limited pilot usability studies. The validity of the design space model and basic navigation operations is examined through the development of a design space navigation framework that encapsulates the model and operations in a software environment and provides the infrastructure and mechanisms for supporting navigation. Three prototype navigation tools are implemented using this framework. These tools are subjected to usability studies. The studies show that these tools are easy to leam and are efficient in assisting designers locating desired information. In summary, it can be demonstrated that through the prototype implementations and usability studies, this approach offers sufficient support for the design and implementation of navigation aids in a generative design system. The research effort is a pioneer study on navigation support in generative design systems. It demonstrates why navigation support is necessary; how to provide the support; and what types of user interaction it can offer. This research contributes to information navigation studies not only in the specific domain of generative design system research, but also in the general field of human-computer interaction.

title	No Times But Principles, A Case Study From Priene, Anatolia
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	To emphasise the reusing of the local identities and cultural effects on contemporary designs, this paper is believed to have an important role for architects and for further designs. In this paper design theories in 1000's BC from Priene is held. The theories in urban and architectural design took place. From the intersection point of Ancient Greek and Western Anatolia, a city named "Priene" is chosen as a point of view because of its speciallocation on the Aegean Sea Coasts; Asia Minor and its design principles on urban and housing scale which were used during 1000's and are still common. Also, in this paper, an analysis is done on urban and housing scale. The analysis has two main parts. In the first part, the important buildings in Priene and their settlement decisions take part. And in the second part, the houses of Priene are explained. The general outputs of the study can be put under two titles: urbanism and architecture. In terms of urbanism, those features of a city image reflecting onto today’s world have been examined and the city of Priene has been analysed in the content of Lynch’s elements ensuring formation of a city image. In terms of architecture, results obtained have been separately examined in the content of today’s architecture as public buildings reflecting unique characteristics of Hellenistic architecture and as settlements. In short, the result that it is wished to reach in terms of city scale of the city of Priene in this study isthe expression of the essence of the historical heritage using a modern language to ensure historical continuity.

title	Spatial Orientation and Wayfinding in Large Scale Virtual Spaces
source	Presence: Teleoperators and Virtual Environments, 7 (2), pp. 101-107
summary	Just as the Pathfinder used the lake and the oak tree to reconstruct his environment, so do we structure our environment with streets and houses, landmarks and guiding principles to aid spatial orientation and wayfinding. The basic process of navigation-extracting information, forming mental representations, and using that representation for route planning and moving about-transcends the physical elements of the environment itself. In practice, we use whatever the environment gives us to solve navigation problems as they arise, in the process, continually refining and updating our internal model of the external environment. Although the virtual environments we speak of may be vastly different in their appearance from the Pathfinder's world, the principles underlying spatial orientation and wayfinding in large-scale virtual spaces have many commonalities.

source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 68-71
summary	This paper evaluates the possibilities for the use of computer aided design and desktop virtual reality technologies as tools for architectural composition. An experimental teaching programme involving undergraduate architectural students at the University of Luton, in which aspects of compositional theory are explored through the direct creation of architectural form and space in digital formats is described. In the programme principles of architectural composition, based upon the ordering and organisation of typological architectural elements according to established rules of composition are introduced to the students through the study of recognised works of design theory. CAD and desktop virtual reality are then used to define and manipulate architectural elements, and to make formal and spatial evaluations of the environments created. The paper describes the theoretical context of the work, assesses the suitability of the software used for performing compositional manipulations, and evaluates the qualities of immersion and intuitive feedback which virtual reality based modelling can offer in the design visualisation process. The teaching programme utilises standard software packages, including AutoCAD, and 3D Studio, as well as Superscape VRT, a PC based desktop VR package.

summary	Numerous scholars in the field of education established that relevance is one of the important instructional components that influence students’ interest and motivation to learn (Bergin, 1999; Frymier and Shulman, 1995; Schumm and Saumell, 1995). Relevance can be achieved by juxtaposing personal experiences with professional scientific principles (Pigford, 1995; Blanton, 1998). In addition to the relevancy of a course substance Blanton (1998) recommends that instructors should introduce the material in an organized system that is relevant to the learner’s life.

title	The Structure of the Ordinary
source	MIT Press, Cambridge, USA, pp. 73-76
summary	According to N. J. Habraken, intimate and unceasing interaction between people and the forms they inhabit uniquely defines built environment. The Structure of the Ordinary, the culmination of decades of environmental observation and design research, is a recognition and analysis of everyday environment as the wellspring of urban design and formal architecture. The author's central argument is that built environment is universally organized by the Orders of Form, Place, and Understanding. These three fundamental, interwoven principles correspond roughly to physical, biological, and social domains. Historically, "ordinary" environment was the background against which architects built the "extraordinary." Drawing upon extensive examples from archaeological and contemporary sites worldwide, the author illustrates profound recent shifts in the structure of everyday environment. One effect of these transformations, Habraken argues, has been the loss of implicit common understanding that previously enabled architects to formally enhance and innovate while still maintaining environmental coherence. Consequently, architects must now undertake a study of the ordinary as the fertile common ground in which form- and place-making are rooted. In focusing on built environment as an autonomous entity distinct from the societies and natural environments that jointly create it, this book lays the foundation for a new dialogue on methodology and pedagogy, in support of a more

summary	This paper focuses on cooperation concepts necessary for managing concurrent engineering. It reports on a research work being done in a project which establishes a connection between computer sciences, architecture, and telecommunications research1. Simple electronic cooperation paradigms (also called generic cooperation bricks) are found by analysing the current usage of human cooperation in the domainof AEC design environments. We introduce the principles of a middleware to build easily cooperative applications to assist cooperative design. In this approach, the design actors choose cooperation forms by instancing adapted generic cooperation bricks.

title	Petri net as a formalism to assist process improvement in the construction industry
source	Automation in Construction 7 (4) (1998) pp. 349-356
summary	One major reason that hinders the implementation of process improvement principles in the construction industry is the lack of a powerful formalism to model and analyze the existing and new workflow processes. This paper proposes a framework which is based on the use of Petri nets for modeling and analyzing workflow processes in construction. The paper starts with an overview of current developments in the Petri nets theory. The paper then presents an example to demonstrate how to use the Petri net based framework to assist important steps of process improvement.
