TY - THES A1 - Zierold, Sabine T1 - Der mediale Raum der Architektur T1 - The medial space of architecture N2 - Der architektonische Raum wird als ein Medium der Kommunikation im Kontext der >neuen< Medien begriffen, aus der Erkenntnis, dass er schon immer ein Medium war und aus einer komplexen Medienstruktur in Abhängigkeit von anderen Medien besteht. Im Prozess von Handlung und Kommunikation ist der architektonische Raum das Medium, das räumliche Nähe von Individuen über alle Sinne und das Bewusstsein gleichzeitig intensiv ermöglicht. Der architektonische Raum als immersives Kommunikationsmedium erreicht im Zeitalter der >neuen< Medien eine neue Dimension, indem mehr und andere Wirklichkeitsalternativen der Kommunikation zur Verfügung stehen. N. Luhmann folgend, wird die Architektur aus der Sicht der Form/Medium-Differenz systemtheoretisch als strukturierter Möglichkeitsraum betrachtet. Der Raum ist das Medium für Formen des architektonischen Raumes, in dem Architektur überhaupt erst wirksam wird. Umgekehrt sind die Formen des architektonischen Raumes Medien für die Wahrnehmung einer Vielzahl von räumlichen Wirklichkeiten. Eine Fassade aus Stein oder Glas ist gebaute Form und kann als Medium Information kommunizieren. Medien werden ihrer Bestimmung um so besser gerecht, je mehr sie sich der Aufmerksamkeit entziehen und wie transparente Fenster hinter der Oberfläche der sinnlichen Wahrnehmung zurücktreten. Als >unwahrnehmbares< Medium ist der architektonische Raum damit eine hintergründige >Wirkungsmacht<, eine Bühne für die Entfaltung von Wirkung, Atmosphäre und Bewegung. Seine physische Wirklichkeit war schon immer durch virtuelle Wirklichkeiten oder Realitäten entgrenzt, die durch Techniken und Technologien der Simulation als künstliche Welten wahrnehmbar und kommunizierbar werden. Dies kann an tradierten Beispielen der gotischen Kathedrale, dem Panorama, den panoptischen Räumen, dem Theater, Kino oder den kontinuierlichen Räumen von der Moderne bis heute aufgezeigt weren. Virtuelle Räume gotischer Glasbilder oder barocker Decken- und Wandbilder im Medium des architektonischen Raumes sind uns geläufig. Die Immersion, das Eintauchen in diese virtuellen Wirklichkeitsspären löst die Wahrnehmung der eigenen körperlichen Präsenz in ihnen aus. Das Potential des virtuellen Raumes der Architektur besteht im Vergleich zu anderen virtuellen Realitäten von Text, Bild oder digitalen Medien in seiner Gebundenheit an die physische, räumliche Reizstruktur, der er die Eindringlichkeit und Komplexität seiner Wirkung verdankt. Es werden unterschiedliche Wechselwirkungen und gemeinsame Entwicklungen von zeitgenössischen Beispielen der Architektur mit den >neuen< Medien aufgezeigt. In der »sensitiven Wand« wird die physische Raumgrenze durch die Integration neuer Techniken und Technologien digitaler, elektronischer Medien etwas extrem Flexibles und Formbares in Interaktion mit dem Benutzer. Der H2O Pavillon (Oosterhuis und NOX, 1997) ist ein Beispiel dafür. Der ausgeprägt polysensorische Immersionsraum steht für die Einheit von digitaler und architektonischer Simulation. Die metaphorische Welt von Höhle und Quelle des Thermalbades Vals (P.Zumthor, 1996) ist die räumliche Reflexion auf die metaphorische Struktur virtueller Räume der >neuen< Medien. Die simulierte Wirklichkeit in den Medien Wasser, Stein und architektonischer Raum produziert schöpferisch den polysensorischen immersiven Zugang in die virtuellen Welten >authentischer< physischer Umgebung. Das >Sichtbare< im Medium Raum der Architektur ist ohne das >Unsichtbare< nicht zu begreifen bzw. das sinnlich Wahrnehmbare nicht ohne das Unwahrnehmbare. Das Erkennen dieser Relation von Form und Medium ermöglicht die Formulierung des neuen Begriffes des medialen Raumes der Architektur, der zur Basis für eine Medientheorie der Architektur wird, als Sichtweise der Entgrenzung des physischen Raumes durch den virtuellen Raum für die subjektive Wahrnehmung, Handlung und Kommunikation. N2 - Within the context of the >new< media, architectonic space must be understood as a medium of communication. This is because it was always a medium, coexisting with other media within a complex media structure. Ensconced as it is within a process of activity and communication, architectonic space is the one medium that facilitates such a close proximity of individuals whose senses and consciousness thus experience a simultaneity of intensity. The architectonic space as an immersive communication medium attained a new dimension in the age of the >new< media, interactive communication availing itself of an increased number of alternative realities. Following the work of N. Luhmann, architecture may be viewed from the perspective of form/medium-difference as a structured space of possibilities within a theory of systems. The space is the medium for forms of architectonic space in the sense that only then does the architecture itself become apparent. The contrary is the case where forms of architectonic space act as media for the apperception of numerous spatial realities. A façade made of stone or glass is built form and as a medium can impart information. The more media abandon their advertence, the better they fulfil their appropriateness and recede like transparent windows behind the surface of animal consciousness. Thus, architectonic space as a >non-perceptible< medium becomes an >agent of power<, a stage for the evolvement of agency, atmosphere and movement/action. Its physical reality was always borderless, not bounded by virtual actualities or realities which are themselves perceivable and communicable as artificial worlds via the techniques and technologies of simulation. Right up to the present day, this is exemplified by artifices such as the Gothic cathedral, the panorama and panoramic spaces, the theatre, the cinema, or the continuous spaces of modernism. Virtual spaces defined by Gothic stained glass or ceiling and wall murals of the Baroque – within the medium of the architectonic space lest we forget – are all familiar to us. Immersion, in the sense of submerging in these virtual sanctums of reality, releases the apperception of each corporeal presence. In comparison to other virtual realities such as text, image or digital media, the potential of the virtual space in architecture arises out of its bondage to the physical and spatial structure of stimuli on which the forcefulness and complexity of its effectiveness depends. Citing examples of contemporary architecture points up various interdependencies between and common evolutions among the >new< media. As new techniques and technologies of digital and electronic media are introduced, the physical spatial border of the >sensitive wall< becomes in terms of interaction increasingly pliable and ductile for the user. The H2O Pavilion (Oosterhuis and NOX, 1997) is just one example. The highly polysensoric immersion space stands for the unity of digital and architectonic simulation. The metaphoric world of caverns and wells of the hot springs at Vals (P. Zumthor, 1996) is the spatial reflexion on the metaphoric structure of virtual spaces as exemplified by the >new< media. The simulated reality in the media water, stone, and architectonic space, enables in an inventive way the polysensoric and immersive access to the virtual worlds of the >authentic< physical environment. That which is >visible< in the medium of architectural space is not understandable without the >invisible<; in other words, the state of sensory perceptibility depends on the existence of the non-perceptible. The recognition of this relation between form and medium allows a new term to be formulated: the >medial space of architecture<. This in turn becomes the basis for a new media theory of architecture itself, a premise defined as a perspective on the debordering of physical space through the virtual one and existing to provide subjective apperception, activity and communication.

Es wird der Frage nachgegangen, inwieweit eine architektonische Strukturierung in der virtuellen Architektur fortzuführen ist, um Handlungs- und Kommunikationsstrukturen zu sichern. Der erste Teil motiviert die Arbeit und vermittelt die Grundlagen und Termini, die in einem direkten Zusammenhang mit der virtuellen Architektur verwendet werden. Der folgende Teil konzentriert sich ausschließlich auf die reale Architektur. Ausgehend vom Element der Wand wird, in einer analytischen und architekturtheoretischen Betrachtung, ein Modell von Raumkategorien entwickelt, welches im Hinblick auf die virtuelle Architektur von besonderer Bedeutung ist. Die aus der Analyse gewonnen Erkenntnisse in Form von Raumkategorien werden im dritten Teil aus der realen in die virtuelle Architektur übertragen. Das folgende Kapitel beschreibt drei Experimente, die Fra-gen, Hypothesen und Ansätze aus den vorangegangenen Kapiteln empirisch evaluieren. Im abschließenden Kapitel werden die Erkenntnisse der experimentellen Untersuchung im Kontext des architektonischen Gestaltens von virtuellen Architekturen diskutiert. N2 - The dissertation explores and evaluates the definition of the architectural category of a wall in virtual architecture. The question to what extent architectural structure can be followed in virtual architecture so that action and communication structures can be transposed is dealt with. The first part motivates the paper and defines the basis and terminology which are used in a direct context with virtual architecture. The following part focuses exclusively on real architec-ture; it reviews the element of the wall under an analytic and theoretical view-point. Moreover, a model of category of space is developed, which is important for virtual architecture. The knowledge gathered from the analysis, in terms of space categories, is then transposed in the third part from real into virtual architecture. The pursuant chapter describes three experiments in which questions, hypothesis and starting points from the previous chapter are empirically evaluated. In the final chapter the results of the experimental investigation are discussed in the context of architectural design.

Although some integrated design automation systems developed for retaining walls and box culverts have expedited the design process of these structures, the process of collecting and distributing the resultant engineering documents has not been fully integrated with the computer applications. We have been developing a Web-based design automation system to manage the resultant documents as well as to speed up the repetitive design process. Manipulation of engineering drawings in the Web page is one of the critical functions needed for Web-based design automation. eXtensible Markup Language (XML) and XML-based vector graphics are expected to facilitate the representation of engineering drawings in the Web page. In this paper, we present how we used XML and Scalable Vector Graphics (SVG) to compose engineering drawings and represent them in the Web page. XML Data Island we designed to define drawing components turned out effective in manipulating the engineering drawings in the Web page.

This course deals with the introduction of Web-based Collaborative Engineering in standard education programmes of water related engineering and civil engineering based on information sharing. Organized under the umbrella of IAHR and ETNET21 this course is collaboration from several universities from all over the world. Started in 1999 the course demonstrates the potential and innovative opportunities of Web-Technology in education, research and engineering: Students from the different partner universities form small distributed teams to solve a given engineering problem in a time window of two weeks. To overcome the spatial distribution the students apply modern Web technology such as video conferencing, application sharing and document management. All results as well as the final reports are presented as Web document on a shared Web-based project platform (http://www.hydro-web.org). Besides the experiences to apply standard Web tools and working methods based on information sharing instead the conventional information exchange in the daily engineering work the students improve their soft skills operate successfully in international and interdisciplinary project environments as part of the ‘Technical Culture’ of nowadays.

An examination of currently available IT-tools shows insufficient support for planning within existing contexts, most notably a deficit with regard to information capture and administration. This paper discusses the concept for a modular surveying system (basic concept, separation of geometry from semantic data, and separation into sub-systems) and the prototypical realisation of a system for the complete support of the entire building surveying process for existing buildings. The project aims to contribute to the development of a planning system for existing buildings. ...

Often these data are given exclusively by paper-based drawings and no digital data such as a computer based product model or even a CAD-model are available. In order to perform mass calculation, damage mapping or a recalculation of the structure these drawings of the building under consideration have to be analysed manually by the engineer. This is a very time-consuming job. In order to close this gap between drawings of an existing building and a digital product model an approach is presented in this paper to digitise a drawing, to build up geometric and topologic models and to recognise construction parts of the building. Finally all recognised parts are transformed into a three-dimensional geometric model which provides all necessary geometric information for the product model. During this import process the semantics of a ground floor plan has to be converted into a 3D-model.

Using the information collected in a building survey the user should be able to “explore” the building in virtual form, as well as to assess the information contained with regard to a specific planning aspect. The functionality provided by an information module should cover several levels of information provision ranging from ‘simple retrieval’ of relevant information to the analysis and assessment of stored information with regard to particular question sets. Through the provision of basic functionality at an elementary level and the ability to extend this using plug-ins, the system concept of an open extendable system is upheld. Using this modular approach, different levels of information provision can be provided as required during the planning process.

This paper describes the theory and approach behind the software realisation of a tool which helps in finding the affine self-weight geometry of gridshell structures. The software tool DOMEdesign supports the formal design process of lattice and grid shell structures based upon the laws of physics. The computer-aided simulation of suspension models is used to derive structurally favourable forms for domes and arches subject to compression load, based upon the input of simple architectonic parameters. Irregular plans, three-dimensional topography, a choice different kinds of shell lattice structures and the desired height of the dome are examples of design parameters which can be used to modify the architectural design. The provision of data export formats for structural dimensioning and visualisation software enables engineers and planners to use the data in future planning and to communicate the design to the client.

Before planning can begin, buildings must be surveyed in whole or in part with the surveying of geometric data playing a dominant role. The geometric survey is typically undertaken using geodetic or photogrammetric measuring techniques and equipment that have been adapted for use in building surveying. Accordingly appropriate technical knowledge is required in order to be able to operate them as well as a considerable financial investment. Such equipment and surveying methods are usually adaptations from other disciplines. The paper discusses and presents approaches to developing “new” equipment for building surveying, devised with the needs of building surveying in mind – redesigns or new designs for surveying tools. The designs are the result of an inter-disciplinary project between the Faculty of Architecture and the Faculty of Product Design at the Bauhaus Universität Weimar.
