title	Directions in modelling environments
source	Automation in Construction 4 (3) (1995) pp. 173-187
summary	Schema definition is a vital component in the computerised A/E/C projects. existing tools to manage this task are limited both in terms of the scope Of problems they can tackle and their integration with each other. This paper describes a global modellling and development environment for large modelling projects. This environment provides a total solution from initial design of schemas to validation, manipulation arid navigation through final models. A major benefit of the described system is the ability to provide multiple views of evolving schemas (or models) in both graphical and textual forms This allows modellers to visualise their schemas and instance models either textually or graphically as desired. The system automatically maintains the Conisistency of the informalion in these views even when modifications are made in other views. Simple and intuitive view navigation methods allow required information to he rapidly accessed. The environment supports strict checking of model instances and schemas in one of the major ISO-standardised modelling languages no used in product data technology. Ill this paper we show how such a modelling environment has been constructed for evaluation in the JOULE founded COMBINE project.

title	A New Methodology to Develop Hypermedia Systems for Architecture History
doi	https://doi.org/10.52842/conf.ecaade.1995.043
source	Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 43-52
summary	This paper illustrates a research project concerning the analysis of architectural works through a comparative study based on hypermedia tools; by exploring the hypermedia, users can find the main subjects relative to the "method " of architectural planning. The use of multimedia in architecture allows the integration in a single system of different types of information which are necessary for the description of a work. texts, designs, photos and sounds. In addition, the hypertext information structure allows the direct intervention on analyzed projects, by pointing out the more important themes and their relationships. Users have the opportunity to immerse themselves in hypermedia and choose the subject to navigate through on each occasion. Our research project aims at developing a prototype concerning two architects. I.L.Kahn and F.L. Wright. The development methodology is based on the key role played by the components of architectonic works, thus allowing users to compare them in a simple and correct way. The methodology used in this work can be extended to other architects or periods, by simply changing the possibility of navigation, i.e. by changing the reading keys.

title	An information engineering approach to modelling building design
source	Automation in Construction 4 (1) (1995) pp. 5-15
summary	This paper highlights potential problems in the construction industry concerning the large quantities of information produced and the lack of an adequate information structure within which to coordinate this information. The Information Engineering Method (IEM) and Information Engineering Facility (IEF) CASE tool are described and put forward as a means of establishing an information structure at a strategic level thus providing a framework for the implementation of lower level applications systems. The paper describes how the ICON (Integration/Information for Construction) project at Salford University is establishing and modelling the information requirements for the construction industry at the strategic level. The IEM and IEF are demonstrated using activity, data and interaction models with particular attention being paid to the function of building design within the broader context of design, procurement and the management of construction. Implications for future practice are also discussed.

summary	We at a new step of software where the development of applications is done not using instructions, but composing applications. The software object oriented which allows the integration between applications is the solution for the designer to produce the own software. It is possible to use integrated applications with a limited knowledge of algorithms and programming languages. That allows the not specialized users to use specialized multimedia tools. The consequences of this opportunity can result very important not only for the designer but above all the actors involved in the decision making process. It is hard to evaluate the social weight of hypertexts and hypermedia in the field of social participation to the decision making. However their efficiency in the communication problem it is clear. We can preview that in the next future the use of hypermedia will be more extensive in the field of decision making, which involve public interests. Some hypertext developed in the CAAD Laboratory of the Third University are briefly described.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 181-185
summary	The quality of the built environment depends critically on the concept of sustainability and, in particular, on designs which are energy efficient and environmentally friendly. This paper gives an account of the successful application of computer-based simulations of the physical environment made available to architects through an Energy Design Advisory Service and used parametrically within a research project carried out jointly with a design and build company. It goes on to indicate how emerging multi-media technology can be used to provide an explanation, particularly to those who are technically unsophisticated, of the complexity of the way in which design decisions impact upon the energy efficiency and environmental friendliness of buildings.

summary	The integration of state-of-the-art photogrammetric methods with the capabilities of CAAD has great potential for a variety of architectural applications. This paper describes the current status of an ongoing research project which aims to develop an easy to use tool for the photogrammetric generation of accurate, reliable and well structured 3D CAAD models of architectural objects. The project adresses the whole range of issues that arise from the digital image acquisition to the data processing, the data integration between photogrammetry and CAAD and the architectural structuring of the geometric data. While also giving a brief overview of the project, the paper concentrates on one central aspect of the system: a method to model what we will define as "weak forms" as the basis for qualitatively controlled computer measurement.

summary	The design problem has a multi-disciplinary nature and the design itself evolves as solutions are attempted by the designer. To support inter-disciplinary communication of design concepts and decisions, the integration of relevant CAAD tools is essential. Based upon a large set of design criteria and all corresponding knowledge, with the help of computer aided design tools, the result could be highly effective and novel. The integration of CAAD tools should be performed on the basis of generating better solutions by enabling designers to manipulate and appraise various solutions quickly and with a minimum of effort. The proposed system provides the foundations for a seamless and continuous working environment for architects and building engineers through a data modelling module, an integrated data management framework and various design tools. In the environment, stand-alone design tools can be plugged-in in order to access information stored in central databases. The suggested data modelling module helps integrated CAAD systems represent and exchange domain dependent design information at a semantic level, such as exchanging components and features of a building rather than graphical primitives. The suggested data management framework supports the straight-forward mechanisms for controlling the data representation through the inter-connected modules and design tools.

summary	Provided multimedia is regarded as the connection of various media for achieving specific goals, the objectives are to he defined very precisely. In architecture, urban and regional planning any confrontation with information in terms of graphics predominantly tends to be represented by visual communication. Thus complex spatial accounts of the facts calling for universally understood representations are conveyed. Despite the fact that presentations have so far mostly appeared as "mixed media" in computer-assisted spatial planning the initial fascination has somewhat faded away. This contribution is to issue concrete working experience with (inter-) national videoconferences via Internet and distributed modelling. Finally, definite solution approaches for the integration of video-conferencing in a simulation- and computer-assisted planning process utilizing multimedia are demonstrated.

title	Retrieval of Similar Layouts in FABEL using AspecT
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 617-626
summary	In the FABEL project several approaches have been developed and published for retrieving similar cases in the domain of architectural design. In this paper we want to focus on a short description and foremost on integration of these approaches. We will introduce the most important approaches. As a first step towards integration, we suggest decomposing them into their main parts: representation of cases, similarity function and retrieval component. Using the first two parts each approach in a new search algorithm operating on a generic data structure, we built a shell called AspecT for an easy integration. We are positive that one can never have fully considered all aspects of a design. Therefore, we describe an open framework to define new aspects and to apply them depending on the context. Unfortunately, openness brings some difficulties along with it. One can not predict the importance of an aspect, until the situation assessment of the query is completed. In other words, it is impossible to define a static distribution of aspect weights that fits for all purposes. As a consequence, one can not predefine a static structure on the case base to speed tip retrieval processes. Dealing with this problem, we developed and published a special search algorithm that passes through a multidimensional case base, finding the best fitting cases within a short amount of time. This algorithm does not need any predefined structure on the case base except aspect specific relations between cases. Creativity of inventing new aspects of cases should not be hindered but one can ask whether or not a certain aspect are worth being regarded in searching for useful cases. The shell AspecT offers a tool to evaluate aspects. At first, formal criteria influence the initial weights of aspects but later on, the contribution of an aspect to find user accepted cases, determines the survival fitness of an aspect. The rule for living or dying is simple. Seldom used aspects disappear, whereas others become stronger. A short description regarding this work is given in last part.

title	Requirements for Virtual Design Review
source	Architectural Research Quarterly 1(2), December
summary	Requirements for Virtual Design Review: Fundamental Argument: This article deals primarily with the actual physical components of a virtual design review, and the difficulties associated with their integration. It is a rather refreshing approach to the problem of the virtual studio, in that it provides an empirical model of how the virtual and the real interact. Needless to say, there were numerous difficulties. 1. The reviewers and the students had to adapt to a new system of design review. Thus, traditional protocols and procedures may or may not work when dealing with a project in the virtual realm. The jurors and the students did become more comfortable as the jury progressed, but it is safe to say that those who went first most likely had a difficult and rather unhelpful session. 2. The technology itself was limited in what it could accomplish. The rate of transmissions across the line often hindered the review. Those students who used analog display, such as drawings or sketches, were not able to present these items effectively to remote viewers. The article does state that the virtual design review drew heavily upon the model of tradition review for its procedures. Was this the correct way of conducting the jury? With the introduction of technology into the process, one would think that there would be a significant shift in the model. Though the traditional model may be useful as a point of departure, we must critically engage the unique qualities that technology brings to the review. I would argue that a new model would need to be developed, whether it is a radical departure, a hybrid, or a modest adjustment to the existing model. For a traditional review, all one might need are a few push pins, a table for model display, and a surface upon which to pin his or her drawings. For the digital review, one requires monitors, computers, special lighting, video cameras, electrical outlets and phone jacks, and whatever else might be required to conduct a successful jury. It is in fact more akin to a television production than a traditional jury. The sheer complexity that technology inserts into the process can seem almost overwhelming. Yet if we can narrow our focus, find the essentials, by critically engaging those areas that will be affected by its introduction, then we can begin to imagine a true digital review.

title	Integration of Digital Photogrammetry and CAAD: Constraint-Based Modelling and Semi-Automatic Measurement
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 35-47
summary	The integration of state-of-the-art photogrammetric methods with the capabilities of CAAD has great potential for a variety of architectural applications. This paper describes the current status of an ongoing research project which aims to develop an easy to use tool for the photogrammetric generation of accurate, reliable and well structured 3D CAAD models of architectural objects. The system essentially consists of a standard CAAD package to which additional functionality was added and a Digital Photogrammetry Station (DIPS), providing semi-automatic computer measurement. The paper concentrates on two main issues in the design of the system: the data-integration and the CAAD-based 3D feature extraction. The data-integration is achieved using a knowledge-base. On top of an adequate data-transfer between the two systems this knowledge-base enables constraint-based modelling in CAAD and qualitatively controlled measurement in DIPS. In the section about Digital Photogrammetry we describe the 3D feature extraction procedure in detail and point out how the qualitative control can be achieved. A practical example is used to illustrate the performance of the system.

title	Implementation of Endoscopic Model Simulation in Teaching - Downtown-Essen
source	The Future of Endoscopy [Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4
summary	Essen with its present population of 630.000 is amongst the six largest cities of the Federal Republic of Germany. Its international significance as former industrial capital of Central Europe stems from its strategically unique location in the center of the largest economic conurbation within Continental Europe. Comparable to the transition during the industrialization period the Ruhr-metropolis, once having been a production site, has become a service-industry site. At present Essen is to be regarded as one of the major trade emporiums in the center of Europe: fair city, headquarters of major international industry- and trade corporations, principal energy center, shopping- and university city. In line with these favorable prerequisites the main traffic corridors, - on the rail, road, water and in the air - of Conti-nental Europe also meet in and around Essen. And the location of the Essen Central Train Station at the geographic center of the Ruhr-agglomeration proves also ideal Its potential regarding urban functionality, however, shows a drastic incongruity as far as aesthetic-atmospheric reality is concerned. Instead of representing a meeting point and the focus for the integration of city quarters in terms of visitors communication it has become cut off from is surroundings in the south and north by large traffic routes. Down-town Essen has become unattractive for the public and thus is avoided rather than visited. An improvement of the Essen down-town area will only be effective if this incongruity is done away with. Therefore, the five-storey system train station is to be connected to the down-town and southern part of Essen on the three major levels level with the vicinity in such a manner that the requirements of its service-function as to representing a point of attraction, animating center and efficient connector are met. Our conception is aimed at turning the Central Train Station into an interesting welcoming- and farewell-place enticing dwelling and appealing business activities: the gateway of Essen and into the world.

title	Algorithm For The Automatic Design Of A Shading Device
doi	https://doi.org/10.52842/conf.acadia.1995.233
source	Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 233-242
summary	Given that there is a need to shade a window from the summer sun and also a need to expose it to the winter sun, this article describes an algorithm to design automatically a geometric construct that satisfies both requirements. The construct obtained represents the minimum solution to the simultaneous requirements. The window may be described by an arbitrary convex polygon and it may be oriented in any direction and it may be placed at any chosen latitude. The algorithm consists of two sequential steps: first to find a winter solar funnel surface; and the second to clip the surface subject to the summer shading conditions. The article introduces the design problem, illustrates the results through two examples, outlines the logic of the algorithm and includes the derivation of the mathematical relations required to implement the algorithm. This work is part of the MUSES project, which is a long term research effort to integrate Energy Consciousness with Computer Graphics in Architectural Design.

title	Dynamic Perspective: The Media Research Programme
source	The Future of Endoscopy [Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4]
summary	This paper focuses on the Research Programme of the Media Sector at the Faculty of Architecture, Delft University of Technology. The media research objectives for the coming years have been brought together with an overall project: “Dynamic Perspective”. The “dynamic” quality may be interpreted both as movement (visual displacement and registration) and as change (the effects of different options). The four projects which together make up this research programme deal with perception (understanding) and conception (designing and imaging) of urban space: “the architecture of the city”. Specific aspects are the effects of primary and secondary spatial boundaries and the systematic structuring of simulation of visual information. The programme will further concentrate on the development and implementation of relevant techniques (besides “traditional” ones such as the drawing and the architectural model, on multimedia techniques such as endoscopy, computer visualization and development of virtual reality systems), both in education and in design practice. By means of analysis, the creation of visual models of choice and the setting up of experiments, the programme aims at the furthering of theoretical knowledge and at acquiring better insights into the effects of design decisions at an urban level, both for designers and for other participants in the design process. Further development of existing laboratory facilities towards a comprehensive Design Simulation Laboratory is an important aspect of the programme. Within the media research process the Aspern location master plan has been considered as a case study, the findings of which will be presented separately in the workshop sessions.

source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 65-78
summary	This paper focuses on results and findings of an educational project, in which the participating students had to develop a design strategy for an urban plan by using and combining endoscopic and computational design visualisation techniques. This educational experiment attempted to create a link between the Media research programme titled 'Dynamic Perspective' and an educational exercise in design composition. It was conceived as a pilot study, aimed at the investigation of emerging applications and possible combinations of different imaging techniques which might be of benefit in architectural and urban design education and potentially for the (future) design practice. The aim of this study was also to explore the relationship between spatial perception and design simulation. The point of departure for the student exercise was an urban masterplan which the Dynamic Perspective research team prepared for the workshop 'the (in)visible city' as part of the 1995 European Architectural Endoscopy Association Conference in Vienna, Austria. The students taking part in the exercise were asked to develop, discuss and evaluate proposals for a given part of this masterplan by creating images through different model configurations using optical and computer aided visualisation techniques besides more traditional design media.The results of this project indicate that an active and combined use of visualisation media at a design level, may facilitate communication and lead to a greater understanding of design choices, thus creating insights and contributing to design decision-making both for the designers and for the other participants in the design process.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 303-311
summary	Using both study models and digital models for schematic design allows us to take advantage of the strengths of each. Models constructed manually benefit from spontaneous juxtapositions and serendipitous interactions with light and gravity. Converting these models into the digital realm allows the computer to take over in areas that it does best: geometric transformation, rigorous analysis, elaboration and co-ordination of details and complexity. As a project develops, CAD/CAM methods can generate forms or components for verifying the virtual representation. The paradigm of porting data to appropriate software tools needs to be extended to exporting out of and into the physical realm. Connecting to models in real space allows us to use senses that are not yet completely addressed by digital models.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 389-397
summary	This paper reviews current 3D CAD building modelling by reference to a large ongoing case study, in which 3D building models and sites are used to generate coordinated drawing, schedule, and visualisation output. It focuses on barriers which current software interpose, preventing more complete use of 3D CAD to integrate building project information systems. Comparisons are made with tools and methodology developed in GIS, in which users make different selections as required from common databases, and it is argued that used in conjunction with 3D CAD building models, they could improve functionality and reduce barriers to effective deployment.

title	SIMULATION - HOW DOES IT SHAPE THE MESSAGE?
source	The Future of Endoscopy [Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4], pp. 47-54
summary	Architectural simulation techniques - CAD, video montage, endoscopy, full-scale or smaller models, stereoscopy, holography etc. - are common visualizations in planning. A subjective theory of planners says "experts are able to distinguish between 'pure design' in their heads and visualized design details and contexts like color, texture, material, brightness, eye level or perspective." If this is right, simulation details should be compensated mentally by trained people, but act as distractors to the lay mind. Environmental psychologists specializing in architectural psychology offer "user needs' assessments" and "post occupancy evaluations" to facilitate communication between users and experts. To compare the efficiency of building descriptions, building walkthroughs, regular plans, simulation, and direct, long-time exposition, evaluation has to be evaluated. Computer visualizations and virtual realities grow more important, but studies on the effects of simulation techniques upon experts and users are rare. As a contribution to the field of architectural simulation, an expert - user comparison of CAD versus endoscopy/model simulations of a Vienna city project was realized in 1995. The Department for Spatial Simulation at the Vienna University of Technology provided diaslides of the planned city development at Aspern showing a) CAD and b) endoscopy photos of small-scale polystyrol models. In an experimental design, they were presented uncommented as images of "PROJECT A" versus "PROJECT B" to student groups of architects and non-architects at Vienna and Salzburg (n= 95) and assessed by semantic differentials. Two contradictory hypotheses were tested: 1. The "selective framing hypothesis" (SFH) as the subjective theory of planners, postulating different judgement effects (measured by item means of the semantic differential) through selective attention of the planners versus material- and context-bound perception of the untrained users. 2. The "general framing hypothesis" (GFH) postulates typical framing and distraction effects of all simulation techniques affecting experts as well as non-experts. The experiment showed that -counter-intuitive to expert opinions- framing and distraction were prominent both for experts and lay people (= GFH). A position effect (assessment interaction of CAD and endoscopy) was present with experts and non-experts, too. With empirical evidence for "the medium is the message", a more cautious attitude has to be adopted towards simulation products as powerful framing (i.e. perception- and opinion-shaping) devices.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 667-672
summary	AgentCAD is a network infrastructure of distributed CAD applications that facilitates the concurrent an cooperative interaction of several designers working together, possibly over several physical locations, on a design project. It provides a set of services and protocols that support the communications of distributed design information captured by CAD drawings, multiple design views, and design changes. It coordinates access to a common and multiple design models as well as the activities of designers based on captured knowledge of designers' tasks, capabilities, and interests, which characterize their behaviors. The idea of AgentCAD represents a departure from the usual way in which CAD applications are used as single-user tools, applied to one view of specific design problems. In describing the AgentCAD environment, we discuss the organization of AgentCAD, its communication model, and the cooperative interaction protocols for designers in the context of a design scenario.
