summary	This paper describes an experimental browser / modeler which will allow the user to collect and assemble virtual kit-of-parts components from "component libraries" located on the Internet (such as manufacturer's databases) and assemble them into a virtual representation of a building. The fully assembled virtual building will provide a basis for ordering and manufacturing actual components and preparing for construction. The browser will allow the designer to affect a limited degree of remote fabrication at real manufacturing facilities, and facilitate eventual interface with built in sensors and actuators. The browser will manipulate and display interactive three dimensional objects using Virtual Reality Modeling Language (VRML). Upon assembly, actual components will have sensors built into them for providing data about the real building, which could be viewed during a walkthrough of the virtual building by clicking on parts of the model. The virtual building will work as a remote facility management tool for monitoring or controlling various architectural devices attached to the real building (such as electrically driven louvers, HVAC systems, appliances, etc.).

title	Multi-sensory user interface for a virtual-reality-based computer-aided design system
source	Computer-Aided Design, Vol. 29 (10) (1997) pp. 709-725
summary	The generation of geometric shapes called `geometric concept designs' via the multi-sensory user interface of a virtual reality (VR) based system motivates the currentresearch. In this new VR-based system, geometric designs can be more effectively inputted into the computer in a physically intuitive way. The interaction mechanism issimilar to the way in which industrial designers sit and discuss concept design shapes across a table from each other, prior to making a final decision about the productdetails. By using different sensory modalities, such as voice, hand motions and gestures, product designers can convey design ideas through the VR-basedcomputer-aided design (CAD) system. In this scenario, the multi-sensory interface between human and computer plays a central role with respect to usability, usefulnessand accuracy. The current paper focuses on determining the requirements for the multi-sensory user interface and assessing the applications of different input and outputmechanisms in the virtual environment (VE). In order to evaluate this multi-sensory user interface, this paper formulates the typical activities in product shape design intoa set of requirements for the VR-CAD system. On the basis of these requirements, we interviewed typical CAD users about the effectiveness of using different sensoryinput and output interaction mechanisms such as visual, auditory and tactile. According to the results of these investigations, a nodal network of design activity thatdefines the multi-sensory user interface of the VR-CAD system is determined in the current research. The VR-CAD system is still being developed. However, voicecommand input, hand motion input, three-dimensional visual output and auditory output have been successfully integrated into the current system. Moreover, severalmechanical parts have been successfully created through the VR interface. Once designers use the VR-CAD system that we are currently developing, the interfacerequirements determined in the current paper may be verified or refined. The objectives of the current research are to expand the frontiers of product design and establisha new paradigm for the VR-based conceptual shape design system.

summary	The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	ARMILLA5 - Supporting Design, Construction and Management of Complex Buildings
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 135-150
summary	ARMILLA5 is a generic computer aided design system, which supports the cooperative design of complex buildings (such as labs, offices or schools) over multiple levels of abstraction. It follows the metaphor of a virtual building site. The designers and engineers meet at a spatial location on the Internet and prepare the building construction by simulating the building site. This article describes the three essential components of the ARMILLA5-model: the geometric model which describes the spatial and physical aspects of the building site, the semantic model which implements passive building components as objects and active building components as applets or applications, and the planning model, which organizes the work steps of the individual engineers and their cooperation. The model is described using different software prototypes written in Objective C, CAD systems and HTML/JAVA.

title	Product Data Model for Interoperability in an Distributed Environment
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 571-589
summary	This paper belongs to a suite of three interrelated papers. The two others are 'The VEGA Platform' and 'A Dynamic Product Model'. These two companion papers are also based on the VEGA project. The ESPRIT project VEGA (Virtual Enterprises using Groupware tools and distributed Architectures) has the objective to develop IT solutions enabling virtual enterprises, especially in the domain of architectural design and building engineering. VEGA shall give answers to many questions of what is needed for enabling such virtual enterprise from the IT side. The questions range from technologies for networks, communication between distributed applications, control, management of information flow to implementation and model architectures to allow distribution of information in the virtual enterprises. This paper is focused on the product model aspect of VEGA. So far modeling experts have followed a more or less centralized architecture (central or central with 4 satellites'). Is this also the architecture for the envisaged goal? What is the architecture for such a distributed model following the paradigm of modeling the , natural human' way of doing business? What is the architecture enabling most effective the filtering and translation in the communication process. Today there is some experience with 'bulk data' of the document exchange type. What is with incremental information (not data) exchange? Incremental on demand only the really needed information not a whole document. The paper is structured into three parts. First there is description of the modeling history or background. the second a vision of interoperability in an distributed environment from the users coming from architectural design and building engineering view point. Third is a description of work undertaken by the authors in previous project forming the direct basis for the VEGA model. Finally a short description of the VEGA project, especially the VEGA model architecture.

title	The integration of communications networks in the intelligent building
source	Automation in Construction 6 (5-6) (1997) pp. 511-527
summary	An Intelligent Building Communications Network (IBN) is a ubiquitous network that integrates Telecommunications, an Intelligent Building Information System (IBIS) and Business Resources over a digital communications platform and has interoperability between systems. Implementation of an IBN is dependent on the migration of IBIS communications networks into the domain of telecommunication and the adoption of Open Systems Interconnection to standardise protocol development. A mechanism suitable to achieve this goal is the Integrated Services Digital Network (ISDN), a fully managed switched network service based on a 64 Kbps channel.

title	Virtual reality interfaces for feature-based computer-aided design systems
source	Computer-Aided Design, Vol. 29 (8) (1997) pp. 565-574
summary	A computer-aided design (CAD) system with a virtual reality (VR) interface simplifies the design of complex mechanical parts. To add a design feature (e.g., a hole,slot, or protrusion), the designer can navigate in the part to the appropriate face of the part where he/she wishes to attach the feature, and sketch directly on that face.Besides convenience, this method of feature specification implicitly enforces feature accessibility constraints, and also provides hints to the process-planner regardingthe order in which the features may be manufactured. We detail the design of a VR-based prototype CAD system. The system maintains the knowledge of part cavitiesand their adjacencies, and a triangulated boundary-representation of an approximating polyhedron. We present incremental provably correct algorithms for updatingthis representation as the user edits the part. We also show how this representation supports real-time displays, navigation, and collision detection. The user-interfaceof the CAD system relies on these capabilities to provide the above-mentioned advantages.

source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	This paper describes a system designed to help architecture students in designing three-dimensional objects in a collaborative way. When implementing this system, VRML (Virtual Reality Modeling Language), Java and Javascript are used. This system uses the World Wide Web, which is getting more and more popular in recent years, as the media to transfer information all over the world. The system allows many users to view three-dimensional objects, change attributes of the objects, discuss and design at the same time. These users can be located in different parts of the world. Each only needs a computer that is connected to the Internet and a web browser that can display VRML objects to use the system. The computer can be any hardware platform running any Operating System. The objective of this project is to develop a system that can run on any computer hardware and software platform. Without any limitation on hardware and software platform, people from different parts of the world can work collaboratively to design architectural objects.

title	Generic representations : an approach for modelling procedural and declarative knowledge of building types in architectural design
source	Eindhoven University of Technology
summary	The building type is a knowledge structure that is recognised as an important element in the architectural design process. For an architect, the type provides information about norms, layout, appearance, etc. of the kind of building that is being designed. Questions that seem unresolved about (computational) approaches to building types are the relationship between the many kinds of instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called ‘prototypes’) face problems clarifying these questions. The research work at hand proposes to investigate the role of knowledge associated with building types in the design process.Knowledge of the building type must be represented during the design process. Therefore, it is necessary to find a representation which supports design decisions, supports the changes and transformations of the design during the design process, encompasses knowledge of the design task, and which relates to the way architects design. It is proposed in the research work that graphic representations can be used as a medium to encode knowledge of the building type. This is possible if they consistently encode the things they represent; if their knowledge content can be derived, and if they are versatile enough to support a design process of a building belonging to a type.A graphic representation consists of graphic entities such as vertices, lines, planes, shapes, symbols, etc. Establishing a graphic representation implies making design decisions with respect to these entities. Therefore it is necessary to identify the elements of the graphic representation that play a role in decision making. An approach based on the concept of ‘graphic units’ is developed. A graphic unit is a particular set of graphic entities that has some constant meaning. Examples are: zone, circulation scheme, axial system, and contour. Each graphic unit implies a particular kind of design decision (e.g. functional areas, system of circulation, spatial organisation, and layout of the building). By differentiating between appearance and meaning, it is possible to define the graphic unit relatively shape-independent.If a number of graphic representations have the same graphic units, they deal with the same kind of design decisions. Graphic representations that have such a specifically defined knowledge content are called ‘generic representations.’ An analysis of over 220 graphic representations in the literature on architecture results in 24 graphic units and 50 generic representations. For each generic representation the design decisions are identified. These decisions are informed by the nature of the design task at hand. If the design task is a building belonging to a building type, then knowledge of the building type is required. In a single generic representation knowledge of norms, rules, and principles associated with the building type are used. Therefore, a single generic representation encodes declarative knowledge of the building type. A sequence of generic representations encodes a series of design decisions which are informed by the design task. If the design task is a building type, then procedural knowledge of the building type is used.By means of the graphic unit and generic representation, it is possible to identify a number of relations that determine sequences of generic representations. These relations are: additional graphic units, themes of generic representations, and successive graphic units. Additional graphic units defines subsequent generic representations by adding a new graphic unit. Themes of generic representations defines groups of generic representations that deal with the same kind of design decisions. Successive graphic units defines preconditions for subsequent or previous generic representations. On the basis of themes it is possible to define six general sequences of generic representations. On the basis of additional and successive graphic units it is possible to define sequences of generic representations in themes. On the basis of these sequences, one particular sequence of 23 generic representations is defined.The particular sequence of generic representations structures the decision process of a building type. In order to test this assertion, the particular sequence is applied to the office building type. For each generic representation, it is possible to establish a graphic representation that follows the definition of the graphic units and to apply the required statements from the office building knowledge base. The application results in a sequence of graphic representations that particularises an office building design.Implementation of seven generic representations in a computer aided design system demonstrates the use of generic representations for design support. The set is large enough to provide additional weight to the conclusion that generic representations map declarative and procedural knowledge of the building type.

title	Developing a new endoscopy laboratory with digital tools.
source	Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary	Tampere School of Architecture had to leave its old down-town building and move to the TU Tampere university campus in Hervanta, 10 km away. In this process, the 20 years old endoscopic system "The Urban Simulator" was one of the victims. Old mechanical parts and especially the original home-built microcomputer system were too old to compete with modern computer-aided methods. A new endoscopical system is now under construction, using all of the 20-year experience, new technical components and computers for camera control and picture processing. Real-material modelling is used together with computer-aided planning and visualization methods taking the best from both sides.

summary	Design is a complex and time consuming process. One way to simplify the design process is to use pre-build blocks for commonly known parts instead of creating them again with CAD. To give the designer an immediate 3D view of the design, designing in virtual reality is a good choice. This paper presents a virtual reality interface tool which allows a user to assemble an architecture structure from a library of pre-built blocks. The library is a distributed client-server database.

title	BACnetTM: a standard communication infrastructure for intelligent buildings
source	Automation in Construction 6 (5-6) (1997) pp. 529-540
summary	Intelligent buildings require integration of a variety of computer-based building automation and control system products that are usually made by different manufacturers. The exchange of information among these devices is critical to the successful operation of the building systems. Proprietary approaches to providing this communication have created great challenges for system integrators and hampered the development of intelligent building technology. Even though digital automation and control technology has been widely available for more than a decade and islands of automation are common, intelligent buildings with integrated building services are still more of a promise than a reality. BACnetTM is a standard communication protocol for building automation and control networks developed by the American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE, Standard 135-1995: BACnetTM--A Data Communication Protocol for Building Automation and Control Networks. American Society of Heating, Refrigerating, and Air-conditioning Engineers. Atlanta, Georgia, USA, 1995). BACnetTM provides the communication infrastructure needed to integrate products made by different vendors and to integrate building services that are now independent. This paper describes the main features of the BACnetTM protocol and early experience implementing it.

source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 80-85
summary	The architectural design business is marked by a progressive increase in operators all cooperating towards the realization of building structures and complex infrastructures (Jenckes, 1997). This type of design implies the simultaneous activity of specialists in different fields, often working a considerable distance apart, on increasingly distributed design studies. Collaborative Architectural Design comprises a vast field of studies that embraces also these sectors and problems. To mention but a few: communication among operators in the building and design sector; design process system logic architecture; conceptual structure of the building organism; building component representation; conflict identification and management; sharing of knowledge; and also, user interface; global evaluation of solutions adopted; IT definition of objects; inter-object communication (in the IT sense). The point of view of the research is that of the designers of the architectural artefact (Simon, 1996); its focus consists of the relations among the various design operators and among the latter and the information exchanged: the Building Objects. Its primary research goal is thus the conceptual structure of the building organism for the purpose of managing conflicts and developing possible methods of resolving them.

title	Integrating Design Tools within a Human Collaborative Working
source	The Int. Journal of Construction IT 5(2), pp. 47-73
summary	This paper stresses the importance of establishing a collaborative working context as the basis for design integration. Within a virtual studio environment framework, a hybrid architecture for design tool integration is presented. Each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A global product model, which is augmented with meta-data description, is employed to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. Collaboration-aware information is modelled and structured through the meta-data model and a tool model. Based on this, mechanisms for tool service coodination in varying modes are developed. It is then illustrated, through an implemented prototype system, how the integrated design tools might be used in human design work.

source	Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 173-188
summary	By looking at computer aided design as design communication we can use pedagogical methods from the well-developed discipline of language learning. Language learning breaks down a complex field into attainable steps, showing how learning strategies and attitudes can enhance mastery. Balancing the linguistic emphases of organizational analysis, communicative intent and contextual application can address different learning styles. Guiding students in learning approaches from language study will equip them to deal with constantly changing technology. From overall curriculum planning to specific exercises, language study provides a model for building a learner-centered education. Educating students about the learning process, such as the variety of metacognitive, cognitive and social/affective strategies can improve learning. At an introductory level, providing a conceptual framework and enhancing resource-finding, brainstorming and coping abilities can lead to threshold competence. Using kit-of-parts problems helps students to focus on technique and content in successive steps, with mimetic and generative work appealing to different learning styles. Practicing learning strategies on realistic projects hones the ability to connect concepts to actual situations, drawing on resource-usage, task management, and problem management skills. Including collaborative aspects in these projects provides the motivation of a real audience and while linking academic study to practical concerns. Examples from architectural education illustrate how the approach can be implemented.

title	Artificial intelligence and networking in integrated building management systems
source	Automation in Construction 6 (5-6) (1997) pp. 481-498
summary	In recent years the emphasis has moved towards integrating all a building's systems via centralised building management systems (BMS). To provide a more intelligent approach to the facility management, safety and energy control in building management systems (IBMS), this paper proposes a methodology for integrating the data within a BMS via a single multi-media networking technology and providing the BMS with artificial intelligence (AI) through the use of knowledge-based systems (KBS) technology. By means of artificial intelligence, the system is capable of assessing, diagnosing and suggesting the best solution. This paper outlines how AI techniques can enhance the control of HVAC systems for occupant comfort and efficient running costs based on occupancy prediction. Also load control and load balancing are investigated. Instead of just using pre-programmed load priorities, this work has investigated the use of a dynamic system of priorities which are based on many factors such as area usage, occupancy, time of day and real time environmental conditions. This control strategy which is based on a set of rules running on the central control system, makes use of information gathered from outstations throughout the building and communicated via the building's data-bus.

title	Creation of concept shape designs via a virtual reality interface
source	Computer-Aided Design, Vol. 29 (8) (1997) pp. 555-563
summary	This paper describes an approach for creating concept shape designs in a virtual reality environment--COVIRDS (COnceptual VIRtual Design System. Conceptdesign refers to the ab initio design of a product or part. In concept design, the product details such as shape features and exact dimensions are not rigidly definedand the designer has some freedom in determining the shape and dimensions of the product. Current CAD require the designer to specify shape and dimensions tocreate CAD models of products even though these are probably not necessary at the concept development stage. COVIRDS overcomes these drawbacks by providing abi-modal voice and hand-tracking based user interface to the VR-based CAD modeling environment. This interface allows rapid concept design creation withoutrequiring time consuming shape description and the tedious specifications of exact dimensions.

summary	Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title	Exploring the Possibilities of Conjoint Measurement as a Decision-Making Tool for Virtual Wayfinding Environments

summary	Virtual reality systems may have a lot to offer in architecture and urban planning when visual and active environments may have a dramatic impact on individual preferences and choice behaviour. Conjoint analysis involves the use of designed hypothetical choice situations to measure individuals’ preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives, called product profiles, are generated and presented to respondents, who are requested to express their degree of preference for these profiles or choose between these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of production profiles. Virtual reality systems offer the potential of moving the response format beyond these traditional response modes. This paper describes a particular aspect of an ongoing research project which aims to develop a virtual reality based system for conjoint analysis. The principles underlying the system will be illustrated by a simple example of wayfinding in a virtual environment.
