title	ACADIA'99: media effect on architectural design
source	Automation in Construction 11 (2) (2002) pp. 131-134
summary	The idea of this conference arose from various discussions between us in various different places.We decided to put a proposal together for bothpositions—Technical Chairs and Site Organizers. This was unprecedented and we were anxious. We really wanted to run this conference and run it in Salt Lake City. Our theme AMedia and Design ProcessB was a timely topic and both of us were working on and around it. We thought it was interesting and challenging to define the terms and to establish the relationships between architecture, representation andmedia. In fact, all throughout the history of architecture, representation, media and design have beenrecognized to have a close relationship. Interpretations as to what exactly this relationship is or meanshave been subject to debate, disagreement and changealong the ages. Whereas much has been said about the dialectics between representation and design, little has been elaborated on the relationship between media and design. Perhaps, it is not until now, surrounded by all kinds of media at the turn of the millennium, as Johnson argues, that we have enough context to be able to see and address the relationship between media and human activities with some degreeof perspective.

title	Interfacing Virtual & Physical Spaces through the Body: The cyberPRINT Project
doi	https://doi.org/10.52842/conf.acadia.2002.395

summary	The cyberPRINT is a fully immersive, interactive virtual environment that is being generated in rea-timebased on physiological data readings of a human body. In other words, the cyberPRINT is based oncreating interfaces between physical and digital spaces and between biology and informationtechnologies. The cyberPRINT is also an event, wherein a performer is connected to the cyberPRINTgenerator to create a self-sustaining feedback mechanism. Although using the body to electronicallydrive music and media events is not new, most of these works have paid little or no attention to thepotential of interactive 3D virtual environments. Nor have they been so technologically advanced,interdisciplinary intensive (involving architecture, choreography, modern dance, music, bioengineering,medicine and computer science), or architecturally focused as the cyberPRINT.This project covers a wide and fertile territory that goes from the very technical and design oriented tothe very theoretical and interdisciplinary. This paper is intended to (1) expand what has been alreadypublished about this project (Bermudez et al 2000a) and (2) establish potential areas for discussionbefore and after the performance

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu 30050, Taiwan The evolution of design media has kept a close relationship with the development of design methods in the history. Nowadays, different computer media have been used in different stages of the design process. It is to believe that computer media have great impact on the design process and methods. The objective of this paper is to realize the design process and methods when designers use computer modeling to tackle an architectural design problem. The methodologies are non- participant observation and retrospection. The findings of this research prove that media does contribute to the changes in design process and methods. Not only does its conclusion help to better understand properties of different media, but also benefit the development of computer media.

title	A Place Where People Are Free to Move: Exploring Dynamic Texture Mapping in Computer Graphic Systems
doi	https://doi.org/10.52842/conf.caadria.2002.117
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 117-122
summary	Recent studies, both collaborative design system and scenario scripting, attempt to explore further CG media. Corbusier pointed out that good architecture is a place where people can walk unrestrainedly and feel free in spirit. However, it is apparent that the human figures are still in animation, whereas they are free to move in the real world. The human figure always plays an important role in the development of design media. The objective of this paper is to develop a new design method using CG media and to study the process of dynamic human texture mapping within the CG. This research conducted a design experiment using computer as the sole design medium. The results show that the new design method not only altered the behavior of the designer, but also impacted design thinking cognition.

title	Virtual Tactility: Working to Overcome Perceptual and Conceptual Barriers in the Digital Design Studio
doi	https://doi.org/10.52842/conf.acadia.2002.325
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 325-331
summary	In the digital age, what is the role of tactility in the digital design process as it is taught in schools ofarchitecture today? Often, students are never taught to appeal to any sense other than sight,particularly now as digital media is embraced as a valuable design tool. Yet, are there some essentialcharacteristics of architecture and the phenomenology of place making that is being cast aside due tothe nature of the tools being used? However true or enigmatic this may be, there is a way of workingand teaching that exists somewhere between the digital and the tactile.This paper postulates a hybrid working environment in the design studio that not only takes advantageof the strengths of various design media, but also focuses on reinterpreting its limits and drawbacks.The ultimate outcome will be a new digital media (intermedia) pedagogy that can revolutionize the waythat we teach architecture and, moreover, computer “aided” design.

title	ENVIRONMENTAL SIMULATION - NEW IMPULSES IN PLANNING PROCESSES
source	Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1, 225 p.
summary	The 5th eaea Conference in Essen yielded four principal findings: • After having been limited to endoscopic picture and film renderings of analog scaled models, the european architectural endoscopy association (eaea) first bridged the gap to digital environmental simulations at this conference. It is not about a better or correct method, but a suitable method of representing the planned reality of a particular project using ways that make sense. The combination of digital and analog simulation media is a source of impetus to the user of both methods. The future belongs to the casespecific application and the numerous integration possibilities of the two different media. • In investigating the perception of pictures produced in both analog and digital form, it was ascertained that it was only after greater effort that the same level of pleasing qualities were achieved in the digital world, compared to pictures of analog scaled models. It seems that for many planning phases model-based pictures are superior to digital photos – with regards to economy, quality of representation and imaginative attributes. This last point seems to be especially important in the draft planning stages: the less sharp a picture is, the more remaining room for viewer interpretation there is. In particular, the high degree of precision characteristic of digital simulations no longer allows room for imagination in the individual viewer. • 3D environmental simulations will increasingly be incorporated with success in architecture and urban design courses at universities and colleges both here in Germany as well as abroad. The further spread of these techniques to other universities and colleges is desirable. Over and above application as a pedagogic tool, the use of these simulations by architects and city planners, private planning agencies and municipal planning administrators will also be in evidence in the future – for checking designs, for informing the involved parties, for establishing the decisions of government bodies, for marketing the project. • Also, the interactive use of endoscopic simulation facilities continually opens new fields of research – whether it be for registering subjective distance perception, whether it be for determining orientation possibilities in open spaces.

summary	Evolution of trends in the realm of computer aided architectural design (CAAD) has seen the convergence of technologies – complementing traditional tools with emerging sciences like Information Technology (IT) and multimedia applications. This appliqué of technologies has not just expanded the scope and enhanced the realm of CAAD research and practice, but is also breaking new frontiers. This creative nexus will be realised at the 7th International Conference on Computer Aided Architectural Design Research In Asia (CAADRIA 2002) to be held at the Faculty of Creative Multimedia, Multimedia University, Malaysia, between 18th-20th April, 2002. CAADRIA 2002’s theme, "Redefining Content", seeks to recognise and infuse these emerging components in the field of architecture and design with a holistic approach towards online, digital and interactive systems. The 41 papers compiled were selected through a blind review process conducted by an international review panel. To reflect the multi-disciplinary nature of this year's conference, the chapters are arranged topically to facilitate the in-depth study of key components. The component sessions include: // Web Design, Database and Networks // CAD, Modelling and Tools // Collaborative Design, Creative Design and Case Reasoning // Simulation and Prototyping // Virtual Environment and Knowledge Management // Design Education, Teaching and Learning /// We believe that this specialised approach will provide a deeper and more illuminating feel of the various components and their critical convergence in the field of architecture and design.

title	A Web-Based Virtual Reality Model for Preliminary Estimates of Hi-Rise Building Projects
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Cost estimating of a construction project at its early stage is considered to be very important task since it will be used as a base to commit or otherwise not to commit funds to that project. Preparation of a reliableand realistic preliminary estimate to aid the decision makers to commit funds for a specific project is a complicated assignment. Traditional methods and operations produced unsatisfactory aid due to lack ofaccuracy especially in the pre-design stage of a project. This participates in the increase of percentage of bankruptcy in the construction industry, which has dramatically climbed up and ranked as 15 percent of thewhole bankruptcies claimed in Canada (Statistic Canada 1998). This paper presents a methodology for developing and a Web-based model to automate preliminary cost estimates for hi-rise buildings. This is achieved by integrating a database with design drawings in a Virtual Reality (VR) environment. The model will automatically generate preliminary estimates after modifying a 3D CAD drawing. It provides the user the option to visualize and simulate the drawing and its cost data through VR environment. Having done that, it will allow owners, architects and cost engineers to view a constructed building project, change its geometric objects and shapes, and accordingly generate a new conceptual cost estimate.

title	Evolution of Media for Early Design Stages
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	In this paper the evolution of media used at early design stages will be considered. In traditional methods of searching and presenting the design idea, the basic tool used was the graphic representation. Implementation of new digital techniques in 60s - 70s focused on the mathematical way ofrepresentation. These methods were “not architect friendly” (lack of graphic representation traditionally used by architects). As a result, the development of methods for digital support of form searching was terminated. The computer was used as a tool for drafting. Creative usage of computers for form searching through sketching on the display was extremely difficult. The computer could be described as an “incompatible pencil”. Only in recent years can we see new efforts in this area ofdesign methodology. Thanks to new technical possibilities we have a new chance for changing the process of designing. New kinds of software and hardware let us use the computer not as a pen, but as a medium. In this paper different new ways of form searching will be considered (from very simple method as the scansketches to very complicated ones, such as the generic algorithms). At the end, the influence of new media on the process of design will be presented.

title	Hybrid Design Environment
doi	https://doi.org/10.52842/conf.ecaade.2002.572
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 572-576
summary	This paper discusses some preliminary ideas concerning new design environment or environment of designing. Main thesis of this paper is that process of creation and perception of architecture proceed between Real and Virtual. Architecture is created by analog and/or digital media. A the result we have the multitude and diversity of spaces and tools. Defining these terms is important for understanding a new process of design and a new space of designing. It gives us possibilities to create the new design environment, in which creation of architectural form may be considered as an integrated process connecting the analog, the digital, the real and the virtual. Architectural space, as we know it from physical environments, is supplemented by a virtual space. Physical, architectural and virtual spaces share very similar features in simulation. In virtual models, the boundary between the representation of physical sites and imaginary, virtual sites is vanishing rapidly, resulting in a new reality.

title	Architectural Composition in Digital Space
doi	https://doi.org/10.52842/conf.ecaade.2003.587
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 587-590
summary	In this paper the possibilities of using the computers at course of architectural compositions are considered. As the start point of the new teaching method of architectural composition we used the course of tradition architectural composition, elaborated at our Faculty. The course of Digital Architectural Composition was finished in 2002. The main goal of using the new digital media for modelling architectural forms was checking the new possibilities of form creation. Traditionally, searching of forms at the conceptual design stage is performed by using sketches, drawings and physical models. Our new method showed that is possible to do the same thing using the computerbased 3D modelling, experiencing no physical limitations of the 'real' substance. At the same time, at the early design stages, when formal value is sought, computer modelling can be done almost intuitively. In ours work we try to find a creative way of using computer - transforming the tool into medium. The attention was paid on exploring the possibilities characteristic for computers and not available with traditional methods of modelling. Architect’s tradition tools are effectively replaced by a computer, which create a new way of doing things.

title	Elitism, IT and the Modern Architect Opportunity or Dilemma
doi	https://doi.org/10.52842/conf.acadia.2002.097
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 97-109
summary	Information Technology (IT) is impacting architecture dramatically in process and form. Often thecurrent transformation of architecture is difficult to analyze and frequently we see confusion and anxietyregarding uncertainties for the future of the architect as designer and project leader. The currentpotentiality for new exotic form (i.e. product) is mesmerizing; however, in the current context, lessobvious issues and pertinent questions are emerging for the profession. What is the mission of theprofession? What will keep us relevant in the mist of the new global society?In this paper, we will take an evolutionary perspective of technology in architecture and draw parallelsbetween the Renaissance, which is the genesis of the modern architect, and the contemporary state ofarchitecture. The modern architect was birthed during the Renaissance where we see the retraction ofthe architect from the building site and separation from direct involvement in the building process.Communications technology (i.e. representation in the form of free-hand drawings, mechanical 2Dorthographic drawings and 3D perspectives) enabled the decomposition of the master builder into threecomponents (i.e. artist-designer, practicing_architect, and builder). Thus, we see technology enable thedenigration and ultimate dissolution of the centuries old craftsman guilds and the master builder. Thetechnology evolution of “drawings” enabled monumental change in the process of architecture over thepast five hundred years. The fission of the master builder, enabled by “drawings”, resulted in disparatefactions which are the forerunners of the modern day litigious design-bid-build project delivery. We nowincreasingly see a return to the fusion of design and building where often the architect is not the projectmanager or leader. Thus, the question looms, will the 21st century architect lead or be led, and whatare the ramifications for the profession?The historical Master Builder is re-emerging as a dynamically networked team of design andconstruction knowledge specialists. Bi-lateral knowledge exchange, enhanced with emerging IT, isoccurring between owners, managers, architects, design specialists, engineers, builders and machines.Technology is disrupting architecture, resulting in increasing specialization and compressed timeframes, and may require reevaluation of the role of the architect as project-leader "integrativegeneralist"or "design-specialist".Conclusively, the concept of ‘cybernetic architecture’ is proposed as an IT reference framework. Failureto appropriately respond to societal evolution, driven by technology, could result in the loss ofprofessional status for the modern architect. Herein lies our dilemma, or opportunity, depending on therole choice of the modern architect.

summary	This paper explores the juxtaposition between architectonic space and virtual environments. It establishes the hypothesis that the intersection of virtual environments with our common life causes a break-up of time and space. Virtual environments are the last and most integral part of the technological revolution, becoming a parallel world, an unlimited extension of our limited world. The spatial and temporal juxtaposition of these two realities creates a new reality of being “inbetween”, it reveals the “inter-media”. This “inter-media” reality is an issue for architecture of our time, and it still lacks of responses.

title	The Dynamics of Physical Ambiences
doi	https://doi.org/10.52842/conf.acadia.2007.174
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 174-181
summary	This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

summary	‘Place’ is arguably an essential component of most successful virtual environments, yet the concept ofwhat is ‘place’, and what sort of ‘placeness’ is required for digital environments, are seldom discussed.A reflexive argument such as here is a place because it was designed to be a place does not stimulatedesign guidelines for virtual places, and it certainly does not help us create and evaluate virtual placessuitable for audiences who vary in intention or in available technology. To articulate useful distinctionsbetween virtual places, this paper extends design guidelines proposed by Kalay and Marx, reshapesthem with the help of Relph’s definitions, into spatial visualisation and activity-based environments, andadds a further category, the hermeneutic. The paper also proposes a graduated matrix for selection ofplacemaking elements and for selecting a mode of representation appropriate to the design objective ofthe virtual environment, be it spatial, activity-based, or hermeneutic.

title	DAM: Digital Animation Museum
source	University of Washington, Design Machine Group
summary	The interaction of architecture and technology is, to many, simply a relationship between a building and the materials from which it is constructed. This thesis, however, explores the notion that architectural spaces and forms are influenced not only by construction technology, but also by everyday technology that we use to better our lives, and particularly focuses on the potential impact of wireless information technology on architecture. This thesis asserts that the implementation of information technology in architecture encourages greater interactivity between building and visitor and also increases flexibility in spatial programming. By incorporating wireless information technology as an essential design element of a museum, traditional notions of control points can be eliminated, and the building experience may be manipulated in a variety of ways to interact with and respond to visitor interests and preferences. In this way, both building and visitors are able to collaborate to produce a unique and individualized experience of the building space.

title	A Bottom-Up Approach to Design Coordination
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	The design industry like any other industry could benefit from process support for its practitioners. However, what constitutes legitimate process support for designers is a difficult research question. In order to support designers in their processes, first one needs to know what designers do. This is not only a question of knowing what designers do in general, but also what particular designers do in their own individual design practice. How to find out what designers do, that is, how to acquire knowledge abouttheir design processes, is also a difficult research question. Providing process support for designers is seen as a task, which cannot be divorced from design process acquisition. That is, one is unlikely to provideprocess support, without acquiring an understanding, what individual designers actually do, and conversely, one is unlikely to acquire an understanding of what designers do, without providing process support for designers. An application whose goal it is to provide both design process support for designers working in collaborative design teams, and also acquires a particular type of design process representationof design processes, is described.

title	Modulating Thermal Mass Behavior Through Surface Figuration
doi	https://doi.org/10.52842/conf.acadia.2017.202
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 202-211
summary	This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

title	Modeling and Rendering Virtual Architecture by Using Fisheye-Panorama-Based Images and Lightings in HDR-Quality
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 172-174
summary	We use digitally made spherical panoramas as background for vr visualisation in architectural sceneries instead of stitched photographs (fisheye-based or serical-mirror-based). For this reason we had the idea to develop the first fisheye-based digitalscanning panorama-camera together with the manufacturer Spheron. The ultimate step in reaching optimal quality not only as a background but also as a source of lighting the background-image is taken as a HDR-image. The high-dynamic-range-technology was developed by the Californian scientist Paul Devebec. High dynamic photographs contain a broader range of information between the very bright zones down to the very dark zones - a lot more than “normal” photographs (digital and analogue), which are named LDR (low dynamic range in comparison to HDR). Some software-products in the field of cad-visualisation in virtual and augmented reality already enable the use of HDR-images and open a new field of controlling daylight and artificial light simulations with photographed backgrounds instaed of synthetic ones. The combination of digitally produced (scanned) spericalimages together with the use of HDR open a wide range of new implementation in the field of architecture, especially in combining synthetic elements in existing buildings, e.g. new interior elements in an existing historical museum).

summary	We use digitally made spherical panoramas as background for vr-visualisation in architectural sceneries instead of stitched photographs (fisheye-based or serical-mirrorbased). For this reason we had the idea to develop the first fisheye-based digital-scanning panorama-camera together with the manufacturer Spheron. The ultimate step in reaching optimal quality not only as a background but also as a source of lighting the background-image is taken as a HDR-image. The high-dynamic- range-technology was developed by the Californian scientist Paul Devebec. High dynamic photographs contain a broader range of information between the very bright zones down to the very dark zones - a lot more than “normal” photographs (digital and analogue), which are named LDR (low dynamic range in comparison to HDR). Some software-products in the field of cad-visualisation in virtual and augmented reality already enable the use of HDR-images and open a new field of controlling daylight and artificial light simulations with photographed backgrounds instaed of synthetic ones. The combination of digitally produced (scanned) sperical images together with the use of HDR open a wide range of new implementation in the field of architecture, especially in combining synthetic elements in existing buildings, e.g. new interior elements in an existing historical museum).
