source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 663-678
summary	Large-scale, three dimensional, interactive computer models of cities are becoming feasible making it possible to test their suitability as a visualisation tool for the design and planning process, for data visualisation where socio-economic and physical data can be mapped on to the 3D form of the city and as an urban information repository. The CASA developed models of the City of Bath and London's West End in VRML format, are used as examples to illustrate the problems arising. The aim of this paper is to reflect on key issues related to interaction within urban models, data mapping techniques and appropriate metaphors for presenting information.

title	A Software for Automatically Verifying Compatibility in Complicated Building Assemblies
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi	https://doi.org/10.52842/conf.ecaade.1997.x.q4q
summary	The research we are carrying on is intended to develop a tool aiding to design building mechanical assembly systems, which are often characterised by high complexity levels. In fact, when designing complicated building assemblies by making use of common graphical representations, it might be impossible for the operator to choose the proper shape and installation sequence of components so that they do not interfere during the assembly, and to check, in the meantime, the most favorable setting up modalities according to execution problems. Our software, running within CAD, by starting from the definition of the node features, will allow the operator to automatically get three types of representation that can simulate the assembly according to the assigned installation sequence: - instant images of the phases for setting up each component into the node; - 3D views showing the position of each component disassembled from the node and indicating the movements required for connection; - the components moving while the node is being constructed. All the representations can be updated step by step each time modifications to the node are made. Through this digital iterative design process - that takes advantage of various simultaneous and realistic prefigurations - the shape and function compatibility between the elements during the assembling can be verified. Furthermore, the software can quickly check whether any change and integration to the node is efficacious, rising the approximation levels in the design phase. At the moment we have developed the part of the tool that simulates the assembly by moving the components into the nodes according to the installation sequence.

title	On-line Handbook to Support Brickwork Design
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi	https://doi.org/10.52842/conf.ecaade.1997.x.v9i
summary	Computer assistants to building design are more and more oriented to construct repertories of cases to be recalled as possible suggestions to a real design situation. For this purpose it is necessary that the cases be described by the parameters most apt to describe the design situations. In this way it will be possible to extract out of the repertory the existing case most akin to the design problem the designer is dealing with. This kind of help is the most fit to the usual behaviour of a designer which, in order to find the best solution to a design problem, resort to his culture, his knowledge of real cases, which he tries to adapt to the peculiar need of his present case. This paper presents an attempt to construct such a tool also if restricted to only one building component: the exterior brickwork. It is structured as an Hypertext, which allows a net of relationships much richer than the one of a conventional handbook.

title	The V.C.net--A digital study in architecture
source	Automation in Construction 6 (4) (1997) pp. 335-339
summary	The V.C.net project is an Internet-based educational and communication tool for the architectural community. Its goal is to encourage students from architecture programs across the country and around the world to examine problems and collaborate in the exploration of ideas through the World Wide Web. The central concept of the project involves the creation of a simulated, vital urban environment constructed from various forms of digital data. This `virtual city' will be comprised of projects executed by students of architecture and urban design in US and abroad. Projects will be proposed for specific sites and will reflect real-world questions as they are mirrored in the virtual world. The city exists as a heuristic tool and is not intended as a copy of any existing human habitat. The ultimate goal of the project is to create a dynamic platform to study the interrelationship of various forces effecting urban development: architecture, planning, civil engineering, economics, social sciences, etc. The project originates at the School of Architecture of the University of Detroit Mercy and is intended to be truly interdisciplinary.

title	Learning and reusing information in space layout problems using genetic engineering
source	Artificial Intelligence in Engineering 11(3):329-334
summary	The paper describes the application of a genetic engineering based extension to genetic algorithms to the layout planning problem. We study the gene evolution which takes place when an algorithm of this type is running and demonstrate that in many cases it effectively leads to the partial decomposition of the layout problem by grouping some activit ies together and optimally placing these groups during the first stage of the computation. At a second stage it optimally places activities within these groups. We show that the algorithm finnds the solution faster than standard evolutionary methods and that evolved genes represent design features that can be re-used later in a range of similar problems.

title	An integrated approach to design and engineering of intelligent buildings--The Intelligent Workplace at Carnegie Mellon University
source	Automation in Construction 6 (5-6) (1997) pp. 401-415
summary	In the past few years, there have been significant advances made in the design and engineering of "intelligent" workplaces, buildings that not only accommodate major advances in office technology but provide better physical and environmental settings for the occupants. This paper will briefly present recent approaches to the creation of innovative environments for the advanced workplace. The architectural and engineering advances demonstrated in Japan, Germany, North America, the United Kingdom, and France can be summarized in four major system categories: (1) enclosure innovations including approaches to load balancing, natural ventilation, and daylighting; (2) heating, ventilation and air-conditioning (HVAC) system innovations including approaches to local control and improved environmental contact; (3) data/voice/power "connectivity" innovations; and (4) interior system innovations, including approaches to workstation and workgroup design for improved spatial, thermal, acoustic, visual, and air quality. In-depth international field studies of over 20 intelligent office buildings have been carried out by a multidisciplinary expert team of the Advanced Building Systems Integration Consortium (ABSIC) based at Carnegie Mellon University. ABSIC is a university-industry-government partnership focused on the definition and development of the advanced workplace. The ABSIC field team evaluated the component and integrated system innovations for their multidimensional performance qualities, through expert analysis, occupancy assessments, and field diagnostics.Based on the results of the case studies and building on the most recent technological advances, the ABSIC team developed the concepts for the Intelligent Workplace, a 7000 square foot living laboratory of office environments and innovations. This project is now under construction at Carnegie Mellon University and its features are discussed in the second section of this paper.

title	Algorithm and Context: A Case Study of Reliability in Computational Daylight Modeling
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 331-344
summary	The systematic use of reliable modeling data is believed to improve the building design quality. The key term here is "reliability". There is general agreement that reliability in the context of modeling- assisted CAAD depends on the accurate description of both contextual parameters (climate, site, etc.) and ~building features (geometric and non-geometric properties) as well as the validity of the underlying simulation algorithms. In this paper, we specifically address the importance of detailed contextual information and computational algorithms for the reliability of the daylight modeling results.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 231-244
summary	Computational building performance modeling typically generates large amounts of data. For this data to become operative information, i.e., provide effective feedback to the design process, it must adequately interface with the informational requirements and procedural characteristics of the building delivery process. Toward this end, this paper specifically addresses the potential of aggregate space-time performance indicators.

title	Design for network communities
source	Proceedings of CHI, ACM Press, New York, pp. 210-217
summary	Collaboration has long been of considerable interest in the CHI community. This paper proposes and explores the concept of network communities as a crucial part of this discussion. Network communities are a form of technology-mediated environment that foster a sense of community among users. We consider several familiar systems and describe the shared characteristics these systems have developed to deal with critical concerns of collaboration. Based on our own experience as designers and users of a variety of network communities, we extend this initial design space along three dimensions: the articulation of a persistent sense of location, the boundary tensions between real and virtual worlds, and the emergence and evolution of community.

title	Comparison of the Effectiveness of Two Computer-Assisted Instruction Methods for Learning Architectural Concepts in Design Studio
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi	https://doi.org/10.52842/conf.ecaade.1997.x.d9t
summary	In design studio, during the preliminary stage of a project, learning architectural concepts through the study of precedents is a common activity. A few computer-based tools for precedent study have been developed, however, most have focused on delivering information without considering aspects of learning concepts. Although the tools apply digital media, such as hypermedia and multimedia, their instructional method is limited to direct instruction for presentation of information. The design and development of the tools neglect the need of the study of concept learning, learners, and learning methods.

title	Auditory collision warning signals for crane operation
source	Automation in Construction 5 (6) (1997) pp. 445-457
summary	This study examined the effect that an auditory collision warning signal's pulse rate, pulse pattern, and onset distance had on subject braking responses in a simulated crane/overhead power line collision scenario. The experimental warning signal alerted subjects of their proximity to overhead power lines. The experimental taks required subjects to monitor a simulated auditory collision warning signal while simultaneously operating a single-axis driving simulation task. The driving task simulated an actual crane operator's mental workload required to navigate a crane and manipulate various loads. Subjects were required to initiate braking responses based on the information conveyed solely through the auditory collision warning system. No visual information was provided to the subjects to isolate the effects of the warning signal. Subjective ratings of the auditory warning signals were obtained to compare subjects' actual performance using the warning signal versus their subjective preferences. Results indicate that subjects were able to initiate appropriate braking responses while using an auditory collision warning signal with moderate onset distances and low pulse rates. The auditory pulse pattern did not have a large impact on subjects' braking responses except at extremely short onset distances. Overall, it was concluded that a pulsing auditory warning signal comprised of a moderate onset distance and low pulse rate could work effectively as a proximity warning device for mobile cranes.

title	Building process summary
source	Automation in Construction 6 (1) (1997) pp. 11-16
summary	There is a lack of research in the UK construction industry. New technologies, particularly communications, are producing rapid change and, if the UK does not exploit this, it will be at the mercy of other countries which do. There is a lack of understanding of the decision making process which inhibits simulation. Clients are likely to exert more influence in future, particularly in building management where 50% of construction workload is on maintenance and repair. Electronic building maintenance manuals are needed. IT suppliers may become more involved and even buy into construction design firms in future. Education is vital to keep the industry at the forefront of IT development and new IT distance learning techniques could help.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 97-115
summary	Design tasks, in particular architectural design tasks, have been found hard to support by means of computers. The main reason for this is that design is a problem solving process, which requires a dynamic way of handling information involved in the design process. The research presented in this paper focuses on this aspect of CAAD: the support of design tasks with dynamic, flexible information modelling techniques. The basic concepts for the developed approach is taken from the field of Feature-based modelling. We briefly review these concepts and then interpret and transport them to the context of architectural design. In defining types of Features, a distinction is made between domain-specific Features and generic Features for which we propose a classification. A framework for the definition and modelling of Features is discussed as well as a prototype Feature-based Modelling Shell based on this framework.

title	Approaching a New Methodology: Integrated Architectural Design on the Basis of 3D Computer Models
source	AVOCAAD First International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-01-09] Brussels (Belgium) 10-12 April 1997, pp. 369-380
summary	The traditional way of architectural design leads to some shortcomings with respect to the quality of the design and the efficiency of the design process. Therefore possibilities for improvements have to be considered. In order to come to fundamental improvements the application of advanced computer technology in the field of architecture has to be coordinated with improvements in the area of design methodologies. In this paper we suggest a new methodology for architectural design. It is based on an integrated manner of designing. Despite some early design steps the whole design process is executed on the basis of a 3D model which is handled by means of computers. The central data objects in the design process are the different types of models. The models contain all relevant information generated in the design process. A comparison of our approach with the traditional way of designing illustrates the potential of the new methodology.

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.
