title	Re-Presentations: Media Inquiries Regarding Architecture

summary	Within the framework of architectural practice as the academy, media supported worldwide interdependence and transient cultural waves are essential forces activating the current globalization phenomenon. Schools that have always engaged themselves in international dialogue, are now increasingly immersed in the rapidly developing media arena and global information networks. In this paper I propose a theoretical and pedagogical framework in which the concept of migration provides a useful model with which to investigate the transitory natures permeating cultures. These involve not only the literal moving from one physical world into another, but also the more abstract - from that of the so called "real" world into that of the "virtual". Through what I call re-presentations an experimental studio was conducted at the Universidad Nacional del Litorat in Santa Fe, Argentina involving multicultures (the USA and Argentina) and multi-disciplines (film/video and architecture). The conclusion suggests however, that such re-presentations posit paradoxical questions.

title	Information systems and the Internet: towards a news counter-revolution?
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The explosive evolution of the Internet into a ubiquitous infrastructure influences the generation, dissemination and use of information. From a historical perspective it redefines issues that have been central to the news and information industry since the seventeenth century. One such issue is periodicity. The practicalities of news media and news as a commodity have resulted into the periodical appearance of news and, by extension, of all actual information. Integral to periodicity iscontrol of information production by institutions or other authorized channels. With the advent of the Internet we are reverting to an a-periodical information system characterized by personalization anddirect contact between information provider and information user. Rather than relying on the institutional status of the propagation channels, we are increasingly evaluating information quality by the integrity, up-to-datedness and reliability of its source. Moreover, we are able to complement orcorroborate information by linking different sources together in compound representations. The extent and complexity of the Internet make search intermediaries necessary. These collect and collate information either ad hoc (responding to a user query) or as part of wider documentation projects. These projects re-introduce institutionalization but the autonomous, intelligent mechanisms used by such intermediaries promote personalization in information retrieval and facilitate decentralization ofinformation supply into a cottage industry. In addition to a-periodicity, directness and wider availability of information, decentralization provides a new social and technical context for precedent and case-based approaches in designing.

summary	Architecture is built information (Schmitt, 1999). Architects have the task of restructuring and translating information into buildable designs. The beginning of the design process where the briefing is transformed into an idea is a crucial phase in the design process. It is where the architect makes decisions which influence the rest of the design development process (Vries et al., 1998). It is at this stage where most information is unstructured but has to be integrated into a broad context. This is where TAP is positioned – to support the architect in finding solutions through the creation of spatially structured information sets without impairing thereby the creative development. We want to enrich the inspiration of an architect with a new kind of information design. A further aspect is workflow in a distributed process where the architect’s work becomes one aspect of a decentralised working patterns. The software supports collaborative work with models, sketches and text messages within an uniform surface. The representations of the various media are connected and combined with each other and the user is free to combine them according to his or her needs.

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	Putting It All Together: Towards a Pattern Language for Interaction Design Reports
source	ACM SIGCHI Bulletin 1998 v.30 n.1 pp.17-23
summary	Pattern languages are representations that have been used in architecture and urban design for about twenty years. They focus on the interaction between physical form and social behavior, and express design solutions in an understandable and generalizable form. But pattern languages are not simply set of patterns intended to be universally applied; instead, they are actually meta-languages which, when used in a particular situations, generate situated design languages. This report describes a CHI 97 workshop which explored the utility of pattern languages for interaction design. We discuss the workshop's rationale, the structure and process of the workshop, and some of the workshop's results. In particular, we describe some patterns developed as part of the workshop, and our consequent reflections on the use of patterns and pattern languages as lingua franca for interaction design. This report concludes with a bibliography on pattern languages and related matters that spans architecture, software design, and organizational design.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	An analysis is made of the relation between the conceptualand paradigmatic level of GIS technologies and the new forms of plan, whichmake environment the center of attention. The intention is to study newcriteria for zoning able to give contextual representations of theterritorial, environmental and landscape aspects of the geographical space,and also to study new legislative principles, able to establish integratedrules for theprojecting of soil uses, the safeguarding and recovery ofenvironmental systems and the tutelage and boosting of the landscape. The experimentation of GIS (Geographical Information System)technologies aims at the construction of systems helping to make decisionsfor the control of the environmental and landscape aspects of theterritory. An analysis is made of the ways in which there are formulated thedescriptions of the various aspects of the environment: the conceptsthrough which knowledge is expressed, the languages used forrepresentations, the cognitive models adopted. GIS technologies have made it possible to represent in an explicitmanner the paradigms underlying the various models of knowledge.Specifically, the following cognitive models have been developed:- ecological models of nature- ecological models of human settlement- ecological models of inhabitants’ mental perceptions

title	Java collaborative interface for architectural simulations A case study on wooden ceilings of Krakow
source	International Conference On Conservation - Krakow 2000, 23-24 November 1998, Krakow, Poland
summary	Concern for the architectural and urban preservation problems has been considerably increasing in the past decades, and with it the necessity to investigate the consequences and opportunities opened for the conservation discipline by the development of computer-based systems. Architectural interventions on historical edifices or in preserved urban fabric face conservationists and architects with specific problems related to the handling and exchange of a variety of historical documents and representations. The recent development of information technologies offers opportunities to favour a better access to such data, as well as means to represent architectural hypothesis or design. Developing applications for the Internet also introduces a greater capacity to exchange experiences or ideas and to invest on low-cost collaborative working platforms. In the field of the architectural heritage, our research addresses two problems: historical data and documentation of the edifice, methods of representation (knowledge modelling and visualisation) of the edifice. This research is connected with the ARKIW POLONIUM co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France) and the Institute HAiKZ of Kraków's Faculty of Architecture. The ARKIW programme deals with questions related to the use of information technologies in the recording, protection and studying of the architectural heritage. Case studies are chosen in order to experience and validate a technical platform dedicated to the formalisation and exchange of knowledge related to the architectural heritage (architectural data management, representation and simulation tools, survey methods, ...). A special focus is put on the evolution of the urban fabric and on the simulation of reconstructional hypothesis. Our contribution will introduce current ARKIW internet applications and experiences: The ARPENTEUR architectural survey experiment on Wie¿a Ratuszowa (a photogrammetrical survey based on an architectural model). A Gothic and Renaissance reconstruction of the Ratusz Krakowski using a commercial modelisation and animation software (MAYA). The SOL on line documentation interface for Kraków's Rynek G_ówny. Internet analytical approach in the presentation of morphological informations about Kraków's Kramy Bogate Rynku Krakowskiego. Object-Orientation approach in the modelling of the architectural corpus. The VALIDEUR and HUBLOT Virtual Reality modellers for the simulation and representation of reconstructional hypothesis and corpus analysis.

title	VRML In Architectural Construction Documents: A Case Study
source	VRML 98 Monterey - Proceedings of the 1998 VRML Conference, pp. 115-120
summary	The Virtual Reality Modeling Language (VRML) and the World Wide Web (WWW) offer new opportunities to communicate an architect's design intent throughout the design process. We have investigated the use of VRML in the production and communication of construction documents, the final phase of architectural building design. A prototype, experimental Web site was set up and used to disseminate design data as VRML models and HTML text to the design client, contractor, and fabricators. In this paper, we discuss the way our construction documents were developed in VRML, the issues we faced implementing it, and critical feedback from the users of the Web space/site. Finally, we suggest ways to enhance the VRML specification which would enable its widespread use as a communication tool in the design and construction industries.

title	Developments in 3D Scanning and Digitizing: New Strategies for an Evolving Design Process

summary	The computer is now a widely accepted tool in architecture as a production and business tool. Acceptance of digital technology as a design aid has been much slower, but continuing developments in ease of use, capabilities, and lower costs are encouraging the use of three-dimensional design modeling. As the demand for 3D design computing grows, peripheral digital technologies are also developing and being integrated. This paper describes on-going research into how current and near-future developments in three-dimensional scanning and digitizing technology that have the potential to substantially change processes of architectural design. Scanners, or digitizers, assist in transforming physical objects and models into digital representations. The capabilities of 3D scanners in architectural design have only begun to be explored. Existing and emerging 3D scanning technologies are briefly described followed by a discussion of sample existing, new, and potential uses of these capabilities as a design tool. An experiment is conducted to contrast the differences between stylus-based and laser-based digitizers in an architectural design environment.

title	Simulation and evaluation of environmental aspects throughout the designprocess
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The evaluation of environmental aspects in architectural design has traditionally been performed by means of simple (and often simplistic) rule systems. These generally remain at the normative level of minimal control one encounters in building rules and regulations, thereby failing to provide sufficient information and clarity for design guidance. Despite this, evaluation results normally bound subsequent design decisions as fundamental, inflexible constraints. At much later design stages, whenarchitectural form has been largely crystallized and when environmental subsystems must be specified in detail, both the architect and the contributing engineers often realize the severe limitation of theinitial choices. A frequently voiced argument for such simplification in the guise of abstraction is the lack of detailed information on the form and functional content of a building in the early stages of the designprocess. This obviously presupposes a tabula rasa generative approach. The application of a priori knowledge in the form of types, cases, precedents and automated recognition permits direct transaction from the abstract to the specific at and between a number of predefined relevant abstraction levels in the representation. The combination of a priori knowledge at the typological level with multilevel representations permits the use of precise simulation techniques already in the early design stages and throughout thedesign process. The simulation results employ the dual representation principle of scientific visualization, thereby linking form with measurable performance. Feedback from the simulation provides the analysis and evaluation means for design guidance and for communication between thearchitect and the contributing engineers. A prerequisite to this is that the abstraction level in the representation constrains the analysis derived from the simulation, e.g., by means of grades of fuzziness applied to different zones in the representation on the basis of information specificity.

title	Making Models Architectural: Protean Representations to Fit Architects’ Minds

summary	A rich vocabulary has evolved for describing architecture. It serves not only as a means of communication, but also as an embodiment of concepts relating to form, space, structure, function, mood, and symbolism. We architects not only speak in terms of walls, rooms, roofs, arches, etc., we see in terms of them and think in terms of them, as well. Such concepts are integral to our ability to design. Typical CAD representations, however, are based on geometric/mathematical elements like points, lines, planes, and symbols. Even more experimental approaches like parametric shapes or procedural assemblies correspond poorly to architectural elements, and seldom lend themselves well to making conceptual changes that would allow exploration of design alternatives. Small wonder some architecture schools experience a division between computer and studio courses, or even between computer and studio faculty. Different ways of talking and thinking are involved. The concepts involved are often mutually exclusive. This paper discusses an attempt to address this conceptual mismatch, using what are termed “protean” (meaning “very changeable”) elements. These are high-level elements corresponding to architectural concepts like “wall,” or “dome.” They each have parameters appropriate for the particular type of element they represent, and produce the polyhedra necessary for graphics based on these parameters. A system is being implemented to allow models to be constructed using these elements. The protean elements form a loosely structured model, in which some elements hierarchically contain others, and some elements are essentially freestanding, being created and manipulated independently of other elements. Characteristics of protean element are discussed, including the underlying object-oriented structure, the relationship between elements and graphics, and functions associated with the objects. A scheme is explained whereby all parts of a design can be represented even when the design includes extremely unusual forms not conforming to predictable classes of elements. The necessary support framework is also discussed; general flow of the system and mechanisms for viewing the model and editing subcomponents are explained. The current status of the project, and intentions for future work are discussed. The project has been partially implemented, and the necessary framework to support the system is mostly complete.

title	Criteria for an object oriented library system of high–level parametric CADelements
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The subject of this paper is the development of criteria and specifications for an object oriented library system of high–level parametric elements that have an integrated 2D and 3D representation. High–levelelements are virtual representations of architectural elements such as windows, doors, etc. High–level parametric elements need few components to be flexible and easily customizable. The generalization ofeach element by its characteristic parts results in a substantial reduction in the number of polygons that must be processed by the computer during the 3D transformation, graphically clean 3D images and low demandon user intervention. Gestalt theory emphasizes the importance of contour lines for the perception of an element. The “minimalist” symbolic representation will simplify contour lines that enhance perception. Theinherent flexibility and functionality of object oriented elements are augmented when the elements are rigorously developed as an object oriented library system, with classes and sub-classes of elements whichinherit characteristics of the parent–class. Attribute values of a parent–class give the user global control over all instances of that class and its sub–classes in the model’s database. The concepts which SystemsTheory uses for making an abstraction of reality are analogous to the concepts used in object oriented programming. This paper describes how Systems Theory is used as tool to develop high–level parametric elements as a functionally and computationally efficient library system.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The TYPOLOGY project was set up by the Dutch Government Building Agency (GBA) to explore computerised representations of buildings that allow analysis of various aspects of their performance. So far this project produced the RF-model, an abstract computerised representation.Physical elements of the building are not represented as such, only individual spaces and boundary segments along which they are adjacent are represented explicitly. Spaces can have any number of functional properties such as the general category of floor area they are included in, the activities they accommodate, or the particular safety compartment or circulation system they belong to. Similarly, boundary segments may, for example, provide access or view, may be included in a particularcategory, such as interior walls, or in a safety or security barrier.The RF-model enabled the presentation and quantitative analysis of design proposals for large and complex buildings such as courts of justice and prison buildings. The model is also used in a multiaspect analysis of a series of recently erected Dutch prison buildings. We expect that these first results will develop into a rich and professional precedent-based system, to be used in the early stages of design. The strategic goal of the project is to derive from the accumulated models and their analysis a more general understanding of the relations between a building’s actual characteristics and various aspects of its performance.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The proliferation of the computer in the documentation of architectural designs generates a growing number of computerized architectural drawings. As a result, practice is showing an increasing interest in the utility of such drawings. This interest is linked to a fundamental promise of computerization in architecture, the analysis and evaluation of a building’s behaviour and performance during the design process. The main drawback of conventional computerized drawings is that they are restricted toplotting orthographic or, less frequently, perspective projections. This effectively reduces the computer to a mere electronic drafting table and computerized drawings to unstructured, haphazard collectionsof arbitrarily chosen graphic elements, normally of the lowest possible complexity. The lack of structure and in particular of meaningful, relevant primitives leads to inadequate support even for basic analyses and evaluations. We consider the structure of computerized design representations with respect to the choice of primitives that facilitate automation of analysis and support focused feedback. We argue that current drawing systems are capable of deriving the basic dual network of ‘solid’ building elements and ‘void’ spaces on the basis of user-input descriptions of familiar entities and that this network is sufficient for normative analyses.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	Computer Aided Animation in Architecture: Analysis of Use and the Views of the Profession

summary	A traditional way to present three-dimensional representations of architectural design has been through the use of manually drawn perspective drawings. The perspective representation assists in the comprehension of the forms and spaces, but is difficult to manually generate. The computer revolution made perspectives much easier to generate and led to a dramatically increased use of three-dimensional representation as a presentation technique. We are just now seeing substantial uses of animation as a communication and presentation tool in architecture. This paper documents the results of two surveys of the architectural profession that sought to discover the current and near future intentions for the use of computer animation. Our belief is that current levels of computer animation use are low, but that many firms intend to start using animation both as a design and presentation tool. In early 1998 we conducted a survey of the uses of computer animation by architectural firms. We posited a set of 14 related hypotheses. This paper represents the tabulated results from 82 completed surveys out of 620 requests. While some level of confidence can be obtained from this sample size, we are publishing in the hope of encouraging continued response to the survey.

title	CAD modelling in multidisciplinary design domains
source	I. Smith (Ed.), Artificial Intelligence in Structural Engineering, Springer, Berlin, pp.335-347
summary	In a multidisciplinary design environment, such as the architecture, engineering and construction (AEC) domain, the various designers will have their own views, concepts and representations of design objects, making communication in a CAD environment a complex task. This paper demonstrates that by taking into consideration the concepts of function and purpose such multiple views and representations can be accomodated. The representation of the functional properties of design objects and their purpose is the underlying basis for the formation of different representations and the coordination of these representations. The paper puts forward definitions for function and purpose which allow for the representation of these properties of a design object and for interdisciplinary communication and integration in a CAD environment.

title	Generation and communication of design information:a building performance simulation perspective

summary	There is general agreement that the process of design and construction of buildings typically involves multiple players. This has been the impetus to develop concepts for computational environments that would supportcollaborative design. While there has been considerable progress with regard to hardware and electronic communication, the underlying representations of design ideas and artifacts have not kept pace with thisprogress. In this paper we deal with this problem not from a global conceptual perspective, but rather from the specific point of view of those designers who use design representation toward extraction and manipulation of specialized technical information. For example, engineers in various fields of building technology require a rich representation of building information in terms of geometry (with special focus on topology), materials, systems attributes, etc. We argue that the current building analysis tools do not operate on the basis of such rich informational representations. Instead the needed information is often assembled on an ad hoc basis from various non-integrated informational sources. We review three representations as they are implemented in commercial or research systems and explore their potential for communicating design information to computational building analysis tools. Based on this review, we describe desirable characteristics of more sophisticated building representations.

summary	This paper investigates the relationship between different design approaches and their effectiveness in the formulation of design concepts. This inquiry will focus on the computer as the sole design and developmental tool. The research employs a short design programme, a small building with a given urban site, as its investigative vehicle. Nineteen second year students of the Mackintosh School of Architecture were monitored and their design progress evaluated. They were split into two groups: one used CAD and AEC as the only drawing and modelling tool, tutorial and review, and another used conventional tools of drawing and model making (mixed media). Structured interviews and personal observations were used as a means for data collection. Questionnaires were administered to students and their response was analysed using the statistical programme SPSS (Statistical Package for the Social Sciences). The Mann-Whitney test was used to test the Null Hypothesis that different design approaches will not produce different design outcomes. Correlation, Regression and the X2 test of independence were also employed to screen data and identify patterns of relationships.
