title	Modeling of Activities: an approach to the virtual representation of human behaviors in architectural spaces tested in emergency units
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	Despite the increasing interest in the functionality and humanization of architecture, there are few studies covering the occupation of buildings and methods to represent activities in spaces. This article explores new software for simulating and virtual modeling in order to facilitate the analysis and visualization of events in buildings. Of particular importance is programming the behavior of 3D-characters according to the probabilistic evolution of activities, and producing animations and interactive models. This approach was tested in a study of three emergency units of hospitals in Chile. Although a full integration of software was not possible, the process developed (in particular the subjective tours) demonstrated that the technique can provide new information about the functioning and spatiality of the units. In addition, it suggested operative and architectural improvements supporting the management and design of facilities.

summary	Describing design as a sequence of steps cannot convey the complexity of social interactions that it embodies. Design is not merely a process, but a co-evolution of efforts and events in various places and times—both synchronous and asynchronous. Designers share their values, effort and expertise within design settings via artifacts that further the design process. Increasingly, these design settings in academia, research, and professional practice combine physical and virtual modalities such as immersion, projection, and a range of interaction technologies. Peter Anders has described such spaces as cybrids: hybrids that integrate virtual and physical space. In these settings, designers use overlapping physical and virtual artifacts and tools to arrive at a co-operative design resolution. Within collaborative design, these artifacts take on an additional role. As embodiments of design ideas and actions, they become media for communication. Donald Schon asserts that design should be considered a form of making, rather than primarily a form of problem solving, information processing or research. Indeed the line separating creation from design is becoming increasingly blurred. For the design artifact itself may become a part of the design proposal—its virtual presence incorporated within a cybrid structure or object. We may in the future see a proliferation of cybrid settings that support collaborative, digital design. The technologies for this already exist in collaborative tools, networked computing, scanning and immersive media. However, it will take a creative vision to see how these disparate tools and devices can integrate within the ideal design setting.

title	Possibilities of applying the E-government management concept in Serbian cities
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Recent urban transformations worldwide consequentially lead to the numerous environmental problems that have to be solved bycomplex structure of social interest groups which have to be included in that process. This demands initiated requisitioning andmodification of concepts and methodologies of planning and managing urban development. At this moment there are differentmodels used in world wide practice, but main bases of new methods and techniques are the same. Leaving the idea of possibility ofconstituting the universal urban planning model lead to very productive results in developing the disciplinary methodologies. Processof transformation of traditional comprehensive urban planning model to integrated procedural pluralistic model (based on sustainabledevelopment principles) is something that can be underlined as a main characteristic of disciplinary development. The questions ofdecision making mechanisms and plans implementation are put in axes of conceptual and methodological considerations. Urbanplanning loses the classic form of making the multi level comprehensive urban plans with exact spatial and time horizon. It means, ingeneral that planning and managing of urban development is aiming to be realistic, decentralized, strategic and problem oriented,arbitrary, not instructive, but understood as a efficient and effective process.Operational support to the this kind of approach are Decision Support IT tools, such as GIS - Geographical Information Systems orES -Expert Systems. Usability of IT tools is based on their capability to perform fast and complicated processing of spatial data andon their flexibility towards specific real problems which are to be solved. In order to use maximum of capabilities of these tools inpractice problem solving it is necessary to adjust their structure and usage to the: - actual conditions of socioeconomic of the contextin which urban development planning and management is performed, - practical demands that managing of urban development has tofore fill, - all participants in urban management process, - institutional mechanisms and procedures.

title	Realestate online information systems
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 561-567
doi	https://doi.org/10.52842/conf.ecaade.2003.561
summary	Several commercial real-estate sites provide listings of available commercial property on the Internet. These listings are generated on the basis of selection criteria as floor area, price and location. Despite the obvious utility of the listings and their promise for the transaction process and market transparency, one third of commercial realestate listing sites went bankrupt in 2001 and 2002. To provide an explanation for the failure, 63 commercial real-estate sites were analysed and classified into three basic business models: the Research / Information model, the Marketing model and the Transaction model. A common success factor for all models is the functionality of the site, especially interaction between the user and the available information. The paper proposes that the transfer of existing architectural representations, information-processing instruments and decision-taking tools is an essential component of future development towards integrated services that accompany a building throughout its lifecycle. This transfer amounts to (1) the addition of building and contextual information from standard documentation and online information services, (2) the derivation and coherent description of programmatic requirements database, and (3) advanced user interaction with building information.

title	Web-Based Computational Design Support Tools Use of Lighting and Energy Performance Simulation and Web-Based Visualization for Energy Integrated Architectural Design
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 307-322
doi	https://doi.org/10.52842/conf.caadria.2003.307
summary	The paper proposes a new methodology how computational lighting and energy performance simulations and web based visualization tools can be employed to support energy integrated architectural design. By studying the current limitations of integrating simulation tools in the design process, the hypotheses of a web-based design guide attempts to establish computational simulation and visualization tools as a value adding part of the design process as well as contribute to the architect's understanding and concerns of energy relationships in buildings. The developed design guide attempts to address the identified limitations by making the actual simulations transparent to the designer physically and figuratively, the latter involving the studying of how to present data as useful information to the designer in post-processing techniques with special focus webbased visualizations.

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 369-372
doi	https://doi.org/10.52842/conf.ecaade.2003.369
summary	The research project in progress in the School of Architecture at the Izmir Institute of Technology includes documentation and reconstruction (by 3D modeling in electronic media) of damaged and lost early modern buildings in the Izmir region. The research aims to analyze the differences between Izmir modern buildings and Universal Modern Style, and preserve information on architectural heritage for future generations. The project is at the phase of developing an interactive web-based historical database (HizmO) that includes data (information, images, technical drawings, VRML models) and visualization of the findings. This database aims to be a pioneer in Mediterranean Region for exhibition of relations between traditional architecture (especially Mediterranean locality) and modernism, and organization of a network and off-campus learning activity for Mediterranean architecture that serve as a guide for students, researchers and architects. This paper aims at introducing this research and discussing the application of the database “HizmO,” its aims and potential effects on education in architectural history.

title	Reflections on e-Design: The e-Studio Experience
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	The influence of digital media and information technology on architectural design education and practice is increasingly evident. The practice and learning of architecture is increasingly aided by and dependant on digital media. Digital technologies not only provide new production methods, but also expand our abilities to create, explore, manipulate and compose space. In contemporary design education, there is a continuous demand to deliver new skills in digital media and to rethink architectural design education in the light of the new developments in digital technology. During the academic years 2001-2003, I had the chance to lead the efforts to promote an effective use of digital media for design education at Department of Architecture, Jordan University of Science and Technology (JUST). Architectural curriculum at JUST dedicated much time for teaching computing skills. However, in this curriculum, digital media was taught in the form of "software use" education. In this context, digital media is perceived and used mainly as a presentation tool. Furthermore, Computer Aided Architectural Design and architectural design are taught in separate courses without interactions between the two.

source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	Genetic information determines the germ of life, the first idea, that encloses all the power of creation. In every "germ" lays the identity, the strength to seek and fulfill expression in form. History, technical and scientific progress require new answers and provide new tools while encouraging investigation. A "Branch", a simple nature element, is reinterpreted into bits of information, reconstructed after being apprehended. This process reveals new elements that could have never been conceived with traditional methods. Nature and Technology complement each other in an embriological growing system that provides a new concept in the construction of real spaces.

title	A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source	Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary	This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.

summary	This paper explains the experience performed by a group of architecture students during a short term worksop, trying to explore the potentials of new approaches and digital technics applied to urban and architectural design. The main purposes were: the inclusion of objetive information and quantitative data of material significance in order to assist the generation and structuring of the design process. The notions of "diagram", "field conditions", "contextual logistic" and "animation" were the conceptual categories employed to approach the dinamic conditions and time related logics as critical aspects of the flexibility associated with material organizations.

title	A Preliminary Model of Community-based Integrated Information System for Urban Spatial Development
source	Proceeding of the 3rd China Urban Housing Conference, July 3-5 2003, Center for Housing Innovations, Chinese University of Hong Kong, ISBN 962-8272-26-8, pp. 417-424
summary	This paper describes a research on building Integrated Information System for Urban Spatial Development. The objective of the research phase discussed in this paper is to define a prototype of information system that basically facilitates information communication among involved participants in an urban spatial development planning. The system is designed by putting stress on local community. Their spatial perception and the availability of GIS technology in local context become constraints in building the system. Internet becomes the main alternative for information dissemination for this phase. This is also supported by the use of web-based GIS as framework of information system. Through few socialization sessions, the proposed model has indicated a prospected alternative to be seamless communication media among participants. To support an easy-access for local people in using this information system a mechanism of information access has been proposed in the form of local information center.

title	The Geographical Alpine Information System “Galpis” in the Raumalp Project. Outlay and Output
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	RAUMALP, an interdisciplinary research project of the Austrian Academy of Sciences, shall examine problem areas of spatial development on community level in the Austrian alpine region. The aim is the investigation of scientific basics for political decision finding, especially for the regional-specific realisation of the Alpine Convention. All ascertained information shall be included in “GALPIS”, a comprehensive Alpine Space Information System. GALPIS based on ESRI ArcGIS and MS Access software works with data from different sources, like ISIS, the electronic data base of Statistic Austria, and original data and maps gathered and elaborated by the working groups of RAUMALP. This also includes ecological raster data. Dealing with administrative units, „real“ space and raster space, RAUMALP will integrate the different space levels mostly to administrative spatial units representing the existing 1145 communities of the RAUMALP study area. This will be realised by overlay of grids, types of land use and communitypolygons. Major task of GALPIS is a conversion of former communal data (p. e. 1451 communities in 1951) that should represent the recent administrative boundaries. By this way it is possible to make thematic and time-integrative analyses of community data. GIS modelling of the six case studies is more complex. The conceptual model has to integrate several vector and raster layers such as land plots (“Digitale Katastralmappe”), types of land use (“Land Use and Land Cover Austria” by M. Seger) and biodiversity. P. e., the working group settlement is using a logical data model based on the entity “building” with the attributes “construction”,“function”, etc.

summary	Digital visualization addresses representational challenges from within and without architecture. ‘Disciplinary’ digital visualization is used to explore, understand and communicate architectural information associated with the production of buildings. 3D modeling, rendering, animation and VR as well as the power of digital media to permit the seamless integration of various data types are unleashing completely new ways to display architecture. As digital power continues to increase and get cheaper, portability and wi-fi networks take root, and visualization work becomes even more main stream, we can expect growing changes in the way the design process is conducted, buildings are presented and documented, and the public and 3rd party’s demands from professional services. This demands a more conscious research/pedagogies aimed at developing new representation conventions.

title	Information Spaces for Mobile City Access
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	This paper describes two complementary European research projects that share common interests and goals.The work described is intended to facilitate city analysis and support decision-making. The first project focuses on the distribution, access and ease of use of city data. The system allows access to historical data concerning key buildings in Liverpool, England, via a suite of web-based tools and a palmtop device. The second project looks at extending the functionality of traditional computer aided design (CAD) software to enable geometric and semantic data to be combined within a single environment. The system allows those involved in city planning to better understand the past and present development pattern of an area so that their decisions on future proposals are better informed.The paper concludes by describing a system that integrates particular aspects of the two projects, and the potential that this integration can bring.This new work provides mobile access to historical city development data, current city information and tools to support urban project development.

title	The pattern of Internet use for information management by architectural practices in the UK
source	Cardiff University, Welsh School of Architecture Cardiff, UK
summary	In recent history, architects have experienced problems related to the use and management of new innovations. The Internet presents one such challenge. It offers considerable expansion in types of communication and sources of business information and connects people and businesses around the globe. As is argued in this research, these services could play a positive role in architectural practice. This research examines the use of the Internet by architectural practices in UK in order to reveal how aware they are of the opportunities it presents, the extent to which they are taking advantage of them, and the problems they are experiencing. A field study was conducted of two types of practices: RIBA private practices and local authority practices. A number of research tools were used to inspect how these practices are using the Internet to manage various types of information that used and produced in the practice, namely: the acquisition of web information, the exchange of the practice’s information through the web and the presentation of the practice’s information on the web. Explanations for the results were sought by correlating variables from the questionnaire study, using simple statistical tests. The field study shows that many Internet services are unpopular among architects, and that practices have problems in adopting and using the technology. The pace at which the Internet is being absorbed and accepted by practices is slow. The study suggests that possible causes are: the little knowledge of users’ about IT, the poor resources of the practice, and old or imperfect Internet installations and the absence of the Internet support to the architect’s activities. The research argues that there are a number of links between these negative factors which make the practice unable to utilize the Internet and to manage the practice’s information through the Internet. To break these links, the research suggests that practices should adopt a specific management strategy to promote more utilization of Internet services in the office and to manage information. Practices need to make certain changes to the way they manage the Internet and work with it, if they plan to integrate the Internet more successfully into their practice. The research discusses techniques for improving practice management which would help practices to digest Internet technology and to use it more effectively in the practice.

doi	https://doi.org/10.52842/conf.acadia.2007.174
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.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	SPOT is a 3D environment for direct sunlight visualization. Implemented in Java 3D, SPOT features two distinct and complementary components: Time Projection and Navigable Animation for virtual interaction. SPOT supports multi-dimensional data visualization including sun angle variations with diurnal and annual cycles in threedimensional space. In SPOT users can sketch on any surface in the 3D environment to indicate the area for simulation. SPOT then generates a spatial distribution representation of the illuminance level on a selected surface over time, rendered with colors of varied gradients. SPOT also enables designers to visualize the temporal information of light distribution over time for a given point. For each point clicked on the 3D model, SPOT generates a calendar diagram where the X and Y axis represent the months of the year and the time of the day. The color of each cell of the calendar is the result of the calculation of the light amount reaching the selected point.
