title	Remote Computer Generated Physical Prototyping Based Design

summary	This research explores some of the opportunities offered by the field of computer aided design. It differs from much of the research in the field in the sense that it extends beyond the boundaries of the computer screen by building and testing a computational and communication design environment made of computers, computer peripherals and digital communication devices. From our observation of the designer's interaction with the computer generated physical prototyping systems we were able to confirm the unique haptic feedback and understanding of complex three- dimensional geometry. We also found limitations of the environment in relation to evolutionary design. It was clear from those experiments with algorithmically generated design alternatives that potentially terrific opportunities lies in their combination with computer generated physical prototypes and manufacturing systems.

title	Experiments in Rule Based Design and Computer Generated Physical Prototypes
source	International Conference on Generative Art
summary	This paper explores some of the opportunities offered by computer aided design to architects, interior designers and industrial designers. It differs from much of the research in the field in the sense that, it expands out of the boundaries of the computer screen by making computer generated physical prototypes using several different Rapid Prototyping technologies.This paper surveys the author's work at the Department of Architecture, Massachusetts Institute of Technology and more recently the work of his research team at the School of Design, Hong Kong Polytechnic University. The aim of the research is to explore the designer's advantages and limitations using rule based design and rapid prototyping techniques and searching for novel research questions. For each of the experiments proposed I will describe (1) the set up of the experiment (2) the methodology used to conduct the experiments, (3) highlights its advantages and limitations and (4) proposes further possible research questions. Throughout the paper I will focus especially on the unexpected outcomes.

title	Virtual Reality Meets Telematics: Design and Development of the Infinity Room
doi	https://doi.org/10.52842/conf.ecaade.1999.466
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 466-472
summary	The paper presents the findings of three years of experimentation in the use of compressed videoconferencing in international virtual design studios. Based on these findings, the authors elaborate on the development of a new videoconferencing interface: "The Infinity Room". The Infinity Room is a design studio space containing a floor-to-ceiling rear projection screen wall that conceals a dark room equipped with 5 video cameras and 4 video projectors that reproduce, on one-to-one scale, the images captured in a similar installation at a remote location. Operationally, the video cameras feed a computer that eliminate image redundancies, codes all the sources into a single entity and sends it as a compressed video signal to a remote computer that decodes and decompresses the images for synchronized delivery through the video projectors. The tiling effect of 4 synchronized and fully interactive video images creates the illusion of an adjacent room. The paper describes the design parameters used in the development of the Infinity Room and elaborates on the technology that makes it feasible. Requirements and constraints on physical space, hardware, software, and networking are discussed. The paper ends with conclusions that highlight the technical feasibility of building a small-scale prototype.

title	Some Phenomena of Spatial Characteristics of Cyberspace
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	"Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

title	Design coordination modeling: A distributed computer environment for managing design activities
source	College of Architecture, Georgia Institute of Technology
summary	The objective of this thesis is to develop an effective multi-user computer environment supporting design collaboration. This research takes a knowledge-based approach to capture meaningful process semantics specified by designers to effectively realize work. It concentrates on establishing a process infrastructure and tools for managing activities for a building design team, with emphasis on remote collaboration and distributed coordination. The results of this research include a design coordination model (DCM) and the prototype of a future generation of distributed coordination environments. DCM provides a digital representation of design processes and support visibility of coordination logic within a CAD environment. Some extended features of distributed coordination are explored in DCM, equipped with a model server that is developed using a web-based three-tier computing system architecture approach.

title	Internet-based collaborative design evaluation : an architect's perspective
source	Harvard University
summary	This research aims at developing a design evaluation system that employs a Product Model as the logical basis for integrating building design and construction processes. The system is implemented with Java language, which allows the system to work over the Internet. Accordingly, the system helps architects to collaborate with remote participants. Thus, this design evaluation system is a building performance evaluator like DOE-2, RADIANCE, HVAC, and the Automated Building Code Checker. This research, however, is mainly concerned with an architect's view during the schematic design and design development stage, while the existing design evaluation systems cover other special consultants' views such as those of HVAC designers, structural engineers, and contractors. From an architect's view, this evaluation system checks the compliance of design objects represented by means of physical objects such as walls and windows and conceptual objects such as rooms as well, to the design criteria focused on accommodating human behavior, rather than other building performances such as sustaining building structures and maintaining indoor livability. As such, the system helps designers analyze and evaluate design solutions according to their original intent. The innovative points of this research lie in the following: (1) Unlike other inquiries, it addresses a systematic evaluation of building design from an architect's view focusing on the experiential quality of the built environment. This research demonstrates that such an evaluation becomes available by introducing human activity-based evaluation. (2) It can take a multi-agenda for several groups of different interests by providing an Aspect Model based on human activity-centered systematic translation of their design considerations and 3D model-based graphical representations into system readable ones. (3) As a result, it addresses the possibility of expanding the capability of the design evaluator from a mere code checker to a general design evaluator while simultaneously, enhancing the availability from stand alone to Internet based networking.

title	Aspects of S2
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 185-196
summary	We present in this paper the essential aspects of the S2 system. This is the internet realization of SEMPER, an active, multi-domain, space-based, object oriented design environment for integrated building performance modeling. The key features of the S2 environment are as follows: A user can access the system regardless of the computer hardware, operating system or the location on a network; geographically distributed users can asynchronously generate a building model through the user interface; this building model can then be simultaneously evaluated with multiple simulation applications running on remote simulation servers; persistent storage is provided for project data and evaluation results; designers using the system have access to multiple libraries that contain building information such as material data, construction types, schedules, and weather data.

title	Implementation of ATM-Based Collaborative Design
doi	https://doi.org/10.52842/conf.caadria.1999.201
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 201-214
summary	The following contribution describes research work in progress within the context of the focal field of research and development "Remote Teamwork (RT)" at Vienna University of Technology. Current research work is aiming at the elaboration of suited collaborative remote-working structures for research and project transactions (incl. study projects) - within the context of spatial planning - on the basis of Asynchronous Transfer Mode (ATM, a technology of broad band telecommunications). The generation and manipulation of digital spatial models and their virtual transportation within large distances represent main objectives. The current subjects in architecture, urban and regional planning (e.g. master planning, building-up planning, urban design, interior design) act as test projects to be defined in the course of the research work in their contents and spatial context and to be represented as digital spatial working models. Special attention is given to consolidation, harmonizing and advancement of current single activities in the field of ATM (e.g. facilitation of the access to technology, definition of project partners at the global level, development of originary, planning- and design-relevant software on the basis of native-ATM).

title	Virtual Heritage: Is There a Future for the Past?
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 482-487
summary	This paper attempts an overview of the contribution which emerging information technologies - viz CAD, Multimedia, Virtual Reality and the Internet - can make to the presentation, understanding and preservation of the rich architectural heritage which exists (pro-term) in almost every cultural context. In the UK, the growing interest in sites such as Stonehenge has, through the threat of greater physical presence, increasingly kept the public at bay - a curious paradox which Virtual Reality (VR) has the potential to address. Virtual Reality (-an overly used and underly understood term-) is an information technology which can provide a convincing experience of environments which: i) exist, but are too remote, costly or hazardous, to visit. ii) don't yet exist but are planned, such as architectural designs or urban plans. iii) never will exist, other than in the imagination. iv) existed in the past and are now threatened or already lost. // This paper has its focus on the latter category, i.e. what is now becoming known as Virtual Heritage (VH), but it puts VH in the context of the broader spectrum of simulated experiences of past, present and future environments of cultural significance. The paper draws largely on the work of ABACUS, the Architecture and Building Aids Computer Unit, Strathclyde. The examples of the application of IT to VH include: i) a virtual reality experience of Historic Scotland's premier historical site: Skara Brae, the most complete neolithic settlement in Northern Europe. ii) a multimedia CD-ROM featuring some 50 of the most wonderful interiors of Glasgow's architectural treasures. iii) a computer based archive of rare and normally inaccessible 17C and 18C drawings of Scottish buildings from three seminal sources. iv) a massive 3-D model of Glasgow (some 10,000 buildings located on the hilly terrain of the city), which is now accessible on the Internet. // The paper concludes with conjectures based on the examples given of how emerging information technologies can help secure a future for the past.

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Visualisation of Design Using Animation for Virtual Prototyping
doi	https://doi.org/10.52842/conf.ecaade.1999.519
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 519-525
summary	Although recent technology in time-based representation has vastly improved, animation in virtual prototype design field remains the same. Some designers invest a huge amount of money in the latest visualisation and multimedia technology and yet may create even worse animation. They often cramp sequences resulting in many viewers failing to interpret the design positively as they miss a lot of vital information that explains the design. This paper basically reports the importance of film-making understanding for producing good virtual prototype animation. It will be based on a part of a research project on the use of time-based media in architectural practices. It also includes an empirical analysis of several architectural-based documentary films (including an interview with the film director) and past and present computer animation. This paper then concludes with recommendations of good techniques for making animated visualisation relative to the stage at which the animation is produced for better design decision.

summary	This research project developed an electronic library of significant buildings chosen to represent seven selected periods of Western architectural history: Egyptian (Mortuary temple of Queen Hatshepsut), Greek (Parthenon), Roman (Pantheon), Romanesque (Speyer Cathedral), Gothic (Notre Dame Cathedral), Renaissance (Tempietto), and Modern (Des Moines Art Center). All buildings were reconstructed in their original or intended forms based on plans, drawings, photographs, and historical texts. Two products were generated by this project: (1) materials to be displayed on the World Wide Web, including rendered still images for perception, movies for a visual guide, and Virtual Reality Modeling Language (VRML) models for user navigation; and (2) virtual reality (VR) models to be displayed in the C2 (an improved version of the Cave Automatic Virtual Environment or CAVE facility). The benefits of these VR models displayed on the Web and in the C2 are their easy accessibility at any time from various geographic locations and the immersive experience that enhances viewersÌ understanding of the effects of spatial proportions on form and of colors on materials.

title	A digital Procedure of Building Construction: A practical project

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.

summary	3D modeling and computer simulations provide new ways for architecture students to study the relationship between the design and construction of buildings. Digital media help to integrate and expand the content of courses in drafting, construction and design. This paper describes computer-based exercises that intensify the students’ experience of construction in several courses from sophomore to senior level. The courses integrate content from drafting and design communication, construction, CAD, and design. Several techniques are used to strengthen students’ awareness and ability in construction. These include: · Virtual design - build projects in which students construct 3D CAD models that include all elements that are used in construction. · Virtual office in which several students must collaborate under the supervision of a student acting as project architect to create a 3D CAD model and design development documents. · Virtual sub-contracting in which each student builds a trade specific 3D CAD model of a building and all of the trade specific models must be combined into a single model. · Construction simulations (4D CAD) in which students build 3D CAD models showing all components and then animate them to illustrate the assembly process. · Cost estimating using spreadsheets. These techniques are applied and reapplied at several points in the curriculum in both technical laboratory courses and design studios. This paper compares virtual construction methods to physical design – build projects and provides our pedagogical arguments for the use of digital media for understanding construction.

title	Towards a Generative System for Intelligent Design Support
doi	https://doi.org/10.52842/conf.caadria.1999.285

summary	In the development of intelligent computer aided design systems, three important issues need to considered. These issues are: how to support the generation of product concepts using evolutionary computation techniques; how to use intelligent databases and constraint management systems for detailed exploration of product embodiment; and how to integrate rapid prototyping facilities for product evaluation. In this paper, we present a brief review of knowledge based design and evolutionary design and discuss ways of integrating both in the development of a generative design system. Based on this review, we present the model and its applications of a generative design system utilizing a number of AI and evolutionary computation techniques. This generative design model is intended to provide a generic computational framework for the development of intelligent design support systems.

summary	Unique to the interior design program at Cornell University is a planned pedagogical approach requiring equal emphasis toward manual and digital graphic communication at the freshman level. Prior to 1998, computer-based instruction only occurred at the junior year of study. Recognizing that cultural and symbolic biases against digital media were formally being instituted by curriculum policy, faculty searched for a new perspective. Central to success was the removal of illogically placed boundaries, both mental and physical. In response, students are now encouraged to cultivate a fluid dexterity between traditional and digital methods, at times using various skills concurrently for design analysis and representation (Figures 1, 2, 3, 4, 5, 6, 7). Course content for DEA115 ranges from basic orthographic drafting, paraline projection, and perspective drawing to color rendering and composition. Students utilize a full range of media: pencil, ink, marker, pastel, AutoCAD, 3DS/ MAX, and Photoshop in this graphics studio. Course meetings total six contact hours per week, constituting a three credit hour class. Assignments are purposefully created to shatter digital myths. For example, instead of a standard, rote drafting exercise, AutoCAD is used to explore design ideas through systemic object manipulation (Figures 8, 9).

summary	Computer based visualisation of 3D models in architecture has been possible for 20 years or more, and the software technology has steadily improved during this time so that now incredibly realistic images can be generated from any viewpoint in a model, and impressive fly through sequences can bring a model to life in ways previously not possible. Virtual reality is with us and multi-media enables us to present a finished design in increasingly seductive ways. However, these forms of output from a 3D model offer much more limited benefits during the design process and particularly on large complex models because they are so computing intensive and it often require many hours to produce just one image. Anything other than a small and relatively simple model cannot be viewed dynamically in real-time on a desktop PC of the type commonly used by architects in a design office. Until now the solution to this problem has meant investing in expensive design review hardware and software with its inherent need for trained, skilled labour. As a result, design review products are often viewed as a luxury or costly necessity.

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 Advice Scheme. 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.

title	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

title	Analysis of a Collaborative Computer Based Design Experience

summary	The design experience referred to in this paper deals with the creative process for developing the pre-design of a new building for the Architecture and Urbanism Department of the Federal University of Santa Catarina / Brazil. The methodological proposition was to develop the design in a collaborative way and to try to use computers from the very beginning of the process. A tri-dimensional computer model was constructed on the sketch phase. Plans, sections and views were generated from this unique 3D model in order to assist development of ideas, coordination and visualization. As soon as the design alterations were defined, the 3D model was updated in order to generate automatic new drawing documents. Due to the number of design team components (8 people) and the high level of design complexity, constant hardcopies were necessary to ease designer’s participation in the idea propositions during meetings.
