title	Arch-OS: An Implementation of Cybrid Strategies
source	Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 282-293

summary	A review of the literature on Intelligent Buildings suggests an ideal of a building as an autonomous system that controls its internal and external environments. The model, whose origin lies with early models of artificial intelligence, effectively treats the building as a slave to human needs, and appears to invest more intelligence in the building than in its occupants. This paper proposes that automated environments be understood as extensions of human sense and awareness. It describes an operating system, Arch-OS, that exemplifies this approach by increasing building occupants’ consciousness of their environment.

title	Development of CAFM System for LCM on Building Maintenance and Management
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 681-692

summary	The purpose of this study is to develop a Computer Aided Facility Management (CAFM) system to assist the optimal Life Cycle Management (LCM) business, especially in the repair and renewal planning works of the inhabited building Life Cycle Cost (LCC). This system is also useful for annual, mid and long term facility maintenance budget planning. Major steps of this study are as follows: (1) A Study on the actual process of the LCM business was undertaken to determine the required functions of the CAFM system. (2) We surveyed the calculation process of the LCC and examined the data processing method in order to determine an efficient LCC calculation method for the CAFM system. (3) Based on the above result, we developed each function required for the CAFM system. (4) The CAFM system was developed by unifying the above functions in a network browser environment such as data transaction management between database, LCC calculation and graphical representation applications. (5) We evaluate the CAFM system by using case studies of LCM works on actual buildings. This system contributes to the efficient maintenance works of the LCC, and is able to support the appropriate scheduling of LCM works.

doi	https://doi.org/10.52842/conf.acadia.2004.150
summary	This paper presents an account of our research and development of processes providing seamless transition from design to fabrication. The narrative of our design, development, and prototyping experi¬ments spans seven years, including our current project, the Trusset software/structural system. Trusset is a combined building system and agent-based software design tool. The building system is based on a differential space-truss designed for fabrication entirely with computer numerically controlled (CNC) linear cutting devices, such as laser cut¬ters or three-axis mills. The software component is a set of agent-based design tools for developing surfaces and envelopes formally suitable to be built using the space-truss structure. Developed in parallel, the soft¬ware and building components combine within the Trusset system to provide a seamless pipeline from design to fabrication and assembly. The story of the development of software components and structural system, leading to the Trusset, act as a means of discussing the larger issues framing the research: the potential pitfalls and benefits of design and fabrication integration via the computer.

title	Designing Generative Sound for Responsive 3D Digital Environment Interaction
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 741-758
doi	https://doi.org/10.52842/conf.caadria.2004.741
summary	This paper examines three key areas of responsive sound interaction in 3D Digital Environments: designing generative sound that derives its composition and relevance from social and physical human interaction within a digital environment; the relation of sonic structure to the digital visual and spatial experience; and responsive, reactive real time sound generation activated by environmental conditions and human behaviours. The primary purposes for responsive sound design are: (1) to provide navigational cues supporting way-finding and spatial orientation; and (2) to provide realtime generative environmental sound that reflects social behaviour in a way that is meaningful and recognisable. The applied contexts for navigational cues and environmental generative sound include online (multi-user), synchronous Virtual Environments and Digital Installation Spaces (e.g. intelligent rooms, virtual reality and immersive environments). Outcomes of responsive sound design include: a trigger system of aural alerts, warnings and guidance; a computational system for generating sound in real time activated by spatial location and social interaction; and an audio (non-visual) tool aiding spatial orientation and way-finding interaction in 3D immersive Digital Environments.

title	Interactive Spaces for Advanced Communication using 3D Video
source	International Journal of Architectural Computing vol. 2 - no. 1
summary	Architects integrate more and more modern information technologies in their projects. Based on this background the use of 3D video in an architectural context is discussed. The combination of real-time 3D video and blue-c technology for a distributed shopping experience in shared virtual shops is described. IN: SHOP illustrates an approach to enhance physical environments in shopping areas and connects geographically distant persons. These technologies offer new architectural design possibilities. The traditional understanding of location, space, and time may be redefined. Interactive spaces are being designed, modified and experienced. We believe that information technologies have an impact on buildings and architecture.

title	Towards Computer Aided Life-Cycle Costing
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	Sustainability is recognised as a necessary public good. Building sustainable buildings requires architectural methods, specifically CAD systems, that include suitable predictions of long term performance. Unfortunately the predominant view in the Building Industries of the Developed world is essentially short term; this is because building developers – not being the end users - are essentially interested in short term profit. Until they can see the ‘value-added’ by sustainability impacting on the selling price of their buildings, they will not be motivated to build ‘sustainably’. This paper describes the issues that have led to this situation. It discussed how the advent of computers has allowed life-cycle data to be gathered over time, and may be included intro CAD system databases to enable sustainability performance predictions to be made. Once made we are now able to reap the benefits by performance benchmarking. The availability of this building performance information on-line is making life-cycle costing more readily available, and more accurate, allowing building developers, owners and users to make rapid and timely feasibility studies well in advance of design. This also allows owners to test various capital to operating cost options in order to get the best economic performance over time, as well as map future capital replacement cycles. These emerging possibilities are discussed in this paper.

summary	Though there have been many successful examples of Virtual Design Studio, there still exist unsuccessful cases in which participants felt dissatisfied or even frustrated, especially at synchronous stages of design communication. A discussion that required designers to refer to 3D models was one of the situations where technical support was insufficient to satisfy the expectation of designers. Assuming that an interactive viewing of 3D models and use of a mark-up utility on a shared PC window could enhance such design communications (though this also requires network bandwidth and computational power) the author conducted experiments in design discussion between two designers to test the capability and effects of these tools for network collaborations. This paper discusses the framework and results of the experiments, and proposes the next step for system developments.

title	Playful and Creative Learning - A Preliminary Model for Digital Design Studio
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 405-418
doi	https://doi.org/10.52842/conf.caadria.2004.405
summary	Hutt (1966) demonstrated that familiarity, clarity, simplicity, and congruity are four stimulus characteristics eliciting play. When the participant reaches this status of an activity, in which is at this point that the playfulness element enters into play, and play is an important ingredient of the creative process. Correspondently, the characteristics in digital design studios which are rapid and broad exploration, systematic design process, the use of suitable digital media, and problem solving system reveal the analogical qualities with play. Since creativity is crucial in design processes, it is worthwhile to study relationships between play and digital design studio to discover possible means to benefit and facilitate digital design learning.

title	A DATA MODEL FOR REPRESENTING CHINESE GARDEN
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 347-362
doi	https://doi.org/10.52842/conf.caadria.2004.347
summary	There are many discussions about spatial consensus or further to “reuse” the design of Chinese Garden in the modern context. For addressing this question, we need to be able to represent the spatial elements of Chinese Garden digitally. However, only few researches in computational design field start to tackle the problem. Furthermore, most of literatures we found are basically the description of abstract or sometime vague concepts. The scope of this research— spatial composition, an efficient description of spatial elements of Chinese Garden in literatures and their relations will be the goal of this research. In this research, we analyze on spatial elements and characteristics of Lin Family Compound to create a suitable database that can offer further researches. For organizing the information we collect, we propose a system called DiGE using the EntityRelationship Data Model. In addition, we will use natural language processing to deal with the unclear data of words depiction.

title	Computer-supported Building Surveying - The Basis for Planning in Existing Built Contexts
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	In view of declining populations and adequate housing provision in the western world, building in existing built contexts is becoming increasingly relevant. The conservation and use of existing buildings stock is not only ecologically sound but also an economic imperative. A prerequisite for computer-aided planning for existing buildings is both the use of on-site computer-aided surveying and the integration of all participants and disciplines in the planning process using integrated information and communication systems. The aim of this research project is twofold: to design a practice-relevant software concept for the support of the entire building surveying process embedded in the planning process, and to develop a practice-oriented mobile, digitally supported equipment and system environment for the digital architectural surveying of buildings. This paper will discuss the IT concept of a building surveying system, the software and hardware prototypes developed as well as usability aspects of wearable computers.

title	Visual Simulation as a Tool for Planning Education - Computer Aided Participation Support
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 500-507
doi	https://doi.org/10.52842/conf.ecaade.2004.500
summary	Contemporary computer techniques offer many new opportunities to engage citizens into the planning process. There are new possibilities of interaction, introducing an observer into the “game”. The research project presented in the paper assumes the use of a visual 3D language which consists of a series of schematic types of buildings. They form a language which is easy to understand both by professionals and by laymen. Understanding is the very first step towards getting convinced by the ideas presented. The next step is interaction - the user’s action induces the response of the system. The solution proposed by the user meets an evaluation from the part of the system which evokes the user’s interest - in the case presented here the evaluation introduces the simulation of future state of the site. The problem posed is to find out the best way to convince people that some places are less or more suitable for settlement, depending on the media present there, distance from the urban areas and the environment protection. The attempt to create a tool which could be helpful in an educational process is described in the paper. The idea is to prepare a form of a master plan record which uses the visual 3D language and may be accessed via World Wide Web pages. The paper formulates the assessments for the software described above and examines the possibility to create an application. The trial to prepare a web based service using the flash and shockwave technology is presented.

title	A model proposal for digitisation and recording data on architectural heritage in Poland based on European guidelines and best practices.
source	University of Strathclyde, Dept. of Architecture and Building Science, Glasgow UK
summary	The aim of the research is an adoption of digital technology in the recording and management of architectural heritage of Poland. The current documentation practice does not fit to the present needs. The existing system of built heritage recording and protection in Poland was developed during the 1960s and the 1970s. It is based on a database of paper fiches. Although the documenting template allows the collection of comprehensive information on historic buildings, the whole system of heritage protection remains petrified. The database verification and upgrade is usually delayed, and moreover, the records do not include some information crucial for successful protection and regeneration of historical buildings. The lack of computer aided documentation system causes, furthermore, inadequate management of the heritage. Central to the research methodology is the belief that a computer aided documentation system for built heritage in Poland should be compatible and harmonised with similar European projects as a response to the needs of the emerging Information Society. To achieve that standards and best practices in Europe were identified, analysed and compared with the current Polish system of heritage protection and management. Activities of Scottish organisations from the cultural heritage sector, being in the forefront of European achievements, were studied in detail. It was observed that Scottish advancements might be a source of valuable lessons and guidelines for similar activities in Poland. The issues crucial to designing a framework model for digitisation and recording data on architectural heritage in Poland were given particular attention. These included aspects related to content, technology, legislation, and project organisation. As a result a number of recommendations were formulated and supported with necessary tables and diagrams. This specification is intended as a starting point for implementation of digital technology in recording and management of architectural heritage of Poland. It is believed that the research outcomes may become useful not only for the architectural heritage documentation and management, but also in the wider cultural heritage sector in Poland. The thesis concludes with a statement that the validity of any guidelines related to the digital technology has a limited lifespan, and therefore the proposed model for digitisation and recording data on architectural heritage in Poland, to be successful, requires constant, diligent review of the technology development.

title	Overview of Intelligent Architecture
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	The concept of intelligent architecture started as an interest in the latest integrated building systems operating a single building or facility, so that systems can communicate and exchange information. The communication among these systems allows the right responses and decisions to operate buildings in a productive, economical and convenient way. Communication and information sharing prevents decisions from interfering with other systems’ responses or operation. Systems’ decisions and responses form the responsive architecture that is represented by systems outputs. If intelligent buildings need to receive, analyze, and react according to such processes, responsive ones are required only to receive and react to only one input parameter. Technology and communication systems make it possible to combine several parameters by using system integration and computerization. Technology and computerized systems have enhanced and changed the manner of responses and provided a variety of decisions according to different sources of information. Receiving, analyzing, and reacting are the key criteria of intelligent building that this paper will explore. The input (reception) category covers information detection devices such as temperature sensors. The second category will be the category of analysing devices. The third category, decisions and outputs, will cover both output of sensory devices and forms of reaction and response that emanate from these systems. As a result of the third category, this paper will survey the forms of responses to determine whether or not the kinetic response is a viable choice. The paper will discuss if these three criteria are the only criteria creating intelligent building or if there are others. The paper will give an overview on intelligent architecture and explore in the main criteria determining intelligent building. The paper will then discuss when “responsive” and "kinetic" architecture becomes “intelligent”. The paper will also redefine the intelligent architecture in the light of available technology.

summary	By exploring interactions between users and information, this paper intends to propose a co-existence framework for companying physical space with virtual space. Based on this framework, we implement an information structure for users to interact with information space interactively, which includes information nodes, hyperlinks and interplays through i-Room system (Chang and Lai, 2003). Furthermore, the information structure of representation is also tested and reevaluated in representing ten historical significant civic buildings in Taiwan.

title	Digital Building Surveying and Planning in Existing Building
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	For planning in existing built contexts, the building survey is the starting point for initial planning proposals, for the diagnosis and documentation of building damages, for the creation of objectives catalogues, for the detailed design of renovation and conversion measures and for ensuring fulfilment of building legislation, particularly by change of use and refitting. An examination of currently available IT-tools shows insufficient support for planning within existing contexts, most notably a deficit with regard to information capture and administration. In ongoing research at the Bauhaus-Universität Weimar (SFB524- Collaborative research center 524 “Materials and Structure in Revitalization of Buildings”) methods and techniques of revitalisation are being investigated (SFB 524, 2004). A special branch of SFB524- D2 entitled “Planning-Relevant Digital Building Surveying and Information Systems” is investigating possibilities of computer-aided building survey and communication platforms for architects and civil engineers. This paper discusses the concept for a modular surveying system (basic concept, structuring of collected data, separation of geometry from semantic data, and separation into sub-systems) and the prototypical realisation of a system for the complete support of the entire building surveying process for existing buildings. The project aims to contribute to the development of a planning system for existing buildings.

title	The use of learning algorithms for real-time immersive data visualization in buildings
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	Computational Fluid Dynamic (CFD) simulations are used to predict indoor thermal environments and assess their response to specific internal/external conditions. Although computing power has increased exponentially in the past decade, CFD simulations are time consuming and their prediction results cannot be used for real-time immersive visualization in buildings. A method that can bypass the time consuming simulations and generate .acceptable. results will allow such visualization to be constructed. This paper discusses a project that utilizes Artificial Neural Network (ANN) as a learning algorithm to predict post-processed CFD data to ensure rapid data visualization. The technique has been integrated with an immersive Augmented Reality (AR) system to visualize CFD results in buildings. ANN was also evaluated against a linear regression model. Both models were tested and validated with datasets to determine their degree of accuracy. Initial tests, conducted to evaluate the user.s experience of the system, indicated satisfactory results.

title	A Multi-dimensional Exploration of Urban Attributes by Data Mining
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. 333-350.
summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.
