title	Collective Pavilions: A Generative Architectural Modelling for Traditional Chinese Pagoda
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 129-138
summary	This paper investigates generative architectural modelling for traditional Chinese architecture and aims to explore and extend the potential of adaptive computing for architectural design methods. The design manners analysis of traditional pagodas architectures is made in a holistic view and under historical perspective. We propose a descriptive model and generative system for the design of traditional Chinese pagodas, by which each pagoda is defined as a collection of style-matched and form-coordinated pavilions and described by both topological graphs and variant geometrical units. Our approach models both of the building geometry and space organization/spatial patterns of pagodas separately. The generative mechanism consists of a framework of grammar-based design and parametric, recursive shape computation. Accordingly, the generative algorithm is also made of two levels, the topology of spatial patterns and the shape geometrical parameters that characterize pavilion variations. The algorithm for computing the former is based on GP (Genetic Programming) and the latter GA (Genetic Algorithms). To explore the collective behaviour of a group of pavilions, multi-agent modelling approach is incorporated in composition patterns search. A prototype system, 'glPagoda', using the OpenGL graphics library for rendering and visualization, has been developed and implemented on PC windows platform.

summary	Cities are becoming more complex in this digital era due to technological changes. Thinking of cities without such technological changes is equivalent to an embryonic state in the morphology of city growth, that is, the growth seems less advanced. So it is appropriate to think of the non digital city digitally. Urban design is one state which establishes the perfect relationship between the street, people and building. The relationship of the people with the building and street is becoming one of the key factors in architecture. It has been observed that the design of a city has been influenced by the pedestrian movement. Many cities prior to the industrial era were largely determined by the social interactions based on walking. Thus the pedestrians play a key role in the formation of the city. They are a very important component in any representation of transport movements. They generally terminate or initiate a chain of linked activities, and if observed carefully, a single pedestrian movement is meant to include various sub journeys from one location to another. In order to organize pedestrians, we need to understand the pedestrian movement system. Though there is a lot of development of urban models in this aspect, it is still in a nascent state in comparison with the digital advancement. Thus much research work is carried out which can be applied to any given environmental setting, and as a result urban designers can respond to the changing socio-cultural technologies.

summary	In South Korea, the changing paradigm of family composition toward single-person households and nuclear families has caused the decrease in number of students, which has led to the need for change in the qualitative, rather than quantitative, management of spaces and facilities on university campuses. In particular, since 2005, the merging of universities have accelerated, which has brought up the need for a system that facilitates the management of integrated university systems. Accordingly, universities now require efficient system operation based on three-dimensional and data visualization, unlike the document-based management of facilities and spaces in the past. Users lack a sense of responsibility for public facilities, causing difficulties such as energy waste and frequent movement, as well as damage and theft of goods. This study aims to form an AR-based interface using the ANPR algorithm, a computer vision technique, and the position-based data of the GPS. It also aims to build a campus space management system to overcome the limitations of current systems and to effectively and systematically manage integrated building data. In addition, for module test verification, the prototype is applied to actual campus spaces, and additional demands for campus space management in the AR application are identified and organized.

title	The continuity style in architectural dynamic visualization
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 468-472
summary	The term “continuity style” in cinema refers to a collection of cinematic conventions aiming at a realistic viewing experience without drawing attention to the elements of illusion used in the representation of 3D space on 2D film. The continuity style underlies the majority of narrative films produced to date and has had a significant influence on other genres, including documentaries. Despite the similarities in purpose, architectural filmmaking owes little to the cumulative knowledge of filmmaking encapsulated in the continuity style. While narrative films focus on the viewing experience, architectural animation tends to be dominated by integral 3D building models. We propose that key elements of the continuity style could be applied to architectural dynamic visualization in order to enhance both lay perception of architectural space and professional analysis of design intentions. These elements refer to four primary areas of architectural dynamic visualization: narrative, camera use, lighting and model structure.

summary	As the first design-build-fabricate-assemble experiment at our school, the intent of the studio was to design a framework from which to examine a “lived space” through digital-to-digital processes. Moving from digital models and physical stereo lithographic models to hand-fabrication and digital assembly allowed the students to move from creation to completion. As part of our holistic design process, the studio fabricated almost all components for the project. These elements include the wood flooring, the copper and wood skins, the building’s structural panels, and the two-story light vortex. This single-family, in-fill house is located within an historic downtown neighborhood and is subject to historic district zoning regulations, design guidelines, and Board of Architecture Review approvals. The project is analogous to design challenges presenting themselves in historic districts throughout the United States including the Savannah, Georgia site for the 2005 ACADIA Conference. The scale of the project relates well to the horizontal nature of this context and after a formal, televised review process with the local Board of Architecture Review, the project represents a dynamic, yet sympathetic architectural dialogue with the surrounding buildings. The project develops simultaneously from the exterior and interior resulting in two courtyards that mediate the urban “front door” and the private “terrace.” The students designed these areas through a series of two-dimensional axonometric drawings, three-dimensional physical and digital models, and four-dimensional time-based animations. The building massing separates into two core elements: gabled copper volume and wood screen volume. These elements maintain their conceptual purity by using the same types of modulations on their skins. The copper form with its deep-cut reveals and proportionally placed light scoring patterns reflects the horizontal datum lines of the floor, sill, threshold, and ceiling. In contrast, the wood volume reflects these same lines as applied “shadow screens” which create depths that seamlessly tie together the side, rear, and front facades.The hinge point of the house is the light vortex. Designed in Rhino, translated in Catia, fabricated out of aluminum, and clad in stainless steel, this two-story sculptural element will literally wrap light around its surfaces. Like a sunflower, the light vortex, with its angel hair stainless steel finish, responds to the incremental differentiation of light throughout the day. Photosensitive floor-mounted lights designed to augment the volume of natural light will provide a continuous light rendition on the sculpture. The project, scheduled for completion at the end of the 2005 summer session, is at the time of this submission about 60% complete.

title	Reinforcement Learning and Real-time Building Thermal Performance Data Visualization
doi	https://doi.org/10.52842/conf.caadria.2005.141
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 141-148
summary	Computational Fluid Dynamics (CFD) simulations are used to predict the fluid behavior and particle systems-in-action in three-dimensional space, allowing experts to evaluate a series of environmental decisions in designing buildings. Although computing power has increased in the past decade, detailed CFD simulations introduce time-delay that defeats the notion of real-time data visualization. A method that can bypass the time-consuming simulations and generate results comparable to detailed CFD simulations will allow such visualizations to be constructed. This paper discusses a pilot project that utilizes a Reinforcement Learning (RL) algorithm coupled with a simplified fluid dynamics equation to generate thermal performance data for real-time visualization.

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.

title	Real-time Simulations Using Learning Algorithms for Immersive Data Visualization in Buildings
source	International Journal of Architectural Computing vol. 3 - no. 3, 265-280
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 still time-consuming and their prediction results cannot be used for real-time immersive visualization in buildings. A method that can bypass the timeconsuming simulations and generate "acceptable" results will allow such visualization to be constructed.This paper discusses a project that utilizes a supervised Artificial Neural Network (ANN) as a learning algorithm to predict post-processed CFD data to ensure rapid data visualization. To develop a generic learning model for a wide range of spatial configurations, this paper presents a pilot project that utilizes an unsupervised Reinforcement Learning (RL) algorithm. The ANN technique was integrated with an interactive, immersive Augmented Reality (AR) system to interact with and 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	Towards a BIM-Based Energy Rating System
doi	https://doi.org/10.52842/conf.caadria.2014.285
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 285–294
summary	Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
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. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

summary	Research and development on Computer Aided Architectural Design often focuses on simulating a building as a digital model. Our research on the early design stages explores concepts we feel are lacking in current design tools and research projects. Building models are usually static models, serving as a snapshot of the design. We aim to support design phase and scale level transitions, to better support the workflow of the designer. This paper formulates our approach at supporting transitions in an integrated design environment for architecture.

summary	This paper describes a computational infrastructure for the realization of a self-updating building information model conceived in the design phase and carried over to the operation phase of a building. As such, it illustrates how computational representations of buildings, which typically serve design support, documentation, and communication functions, can be transported into the post-construction phase. Toward this end, we formulate a number of requirements for the conception and maintenance of life-cycle building information models. Moreover, we describe the architecture and the prototypical implementation of such a model.

title	From Bézier to NURBS: Integrating Material and Digital Techniques through a Plywood Shell
doi	https://doi.org/10.52842/conf.acadia.2005.156

summary	The development of digital fabrication has reintroduced material processes with digital processes. There has been much discussion about the tool and the objects of the tool, but little discussion of the implication of the material process on the digital process. A brief historical review on the development of computer numerical control and the origins of the Bézier curve reveals an instrumental fact: computer numerical controlled tools necessitated advancements in computational surfaces which eventually led to NURBS (Non-Uniform Rational B-Splines) surfaces. In other words, the origins of NURBS surfaces resides in its relation to material processes, rather than many current approaches that develop free form surfaces and then force the tool onto the material without regard to the material properties. From this historical and mathematical review, this project develops toward more intelligent construction methods based on the integration of NURBS differential geometry paired with material qualities and processes. Specifically, a digital technique of developing conceptual NURBS geometry into piecewise surface patches are then flattened based on the material thickness and density. From these flattened patches, a material technique is developed to intelligently remove material to allow the rigid flat material to re-develop into physical surface patches. The goal of this research is to develop digital and material techniques toward intelligent construction based on the correspondence between digitally driven surface and digitally driven material processes. The application of this technique as a rational and flexible system is to support the dynamic response of form and material toward such performative aspects as structure, daylight, ventilation, and thermal properties.

title	Three-Dimensional Shape Generation of Low-Energy Architectural Solutions using Pareto Genetic Algorithms
doi	https://doi.org/10.52842/conf.ecaade.2005.647
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 647-654
summary	This paper extends on a previous work on the application of a Generative Design System [GDS] to the evolution, in a computational environment, of three-dimensional architectural solutions that are energy-efficient and adapted to the climatic environment where they are located. The GDS combines a well-known building energy simulation software [DOE2.1E] with search procedures based on Genetic Algorithms and on Pareto optimization techniques, successfully allowing to tackle complex multi-objective problems. In the experiments described, architectural solutions based on a simplified layout were generated in response to two often-conflicting requirements: improving the use of daylighting in the space, while controlling the amount of energy loss through the building fabric. The choice of a cold climate like Chicago provided an adequate framework for studying the role of these opposing forces in architectural form generation. Analysis of results shows that building characteristics that originate successful solutions extend further than the building envelope. Issues of massing, aspect ratio, surface-to-volume ratio, orientation, and others, emerge from the analysis of solutions generated by the GDS, playing a significant role in dictating whether a given architectural form will prove adapted to its climatic and energy requirements. Results suggest that the questions raised by the exploration of form generation driven by environmental concerns are complex, deserving the pursuit of further experiments, in order to better understand the interaction of variables that the evolutionary process congregates.

title	A 3D Model of the Inner City of Beijing
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 63-72
summary	This study has two major concentrations: 1) exploring methods of creating a digital city model, and 2) applying the model to study urban spatial structure, an issue of particular interest and importance to urban planners. Based on existing studies that primarily address two-dimensional (2D) urban structure, this paper focuses on the three-dimensional (3D) structure relating to the 3D urban form. Given their greater clarity and possibilities for quantitative analysis, both 3D digital urban models and GIS spatial overlay analysis methods hold tremendous potential for analysing and predicting future urban form. In this project, the Xidan Business District in Beijing's Inner City was the area selected to implement the digital-city application. Under the hypothesis that the existing urban spatial structure is determined by the city's urban planning scheme and current urban marketing forces, it is found that actual urban development does not follow the planning restrictions on zoning and building height regulations. Some contradictions and conflicts, such as building location and height, appeared in the studied district. The specific reasons for the discrepancies need to be further studied.

summary	This study attempts to investigate the sense of presence in a fully immersive virtual environment. The methodology applied in this study used protocol analysis for data collection. A preliminary experiment was conducted to explore noticeable phenomena to develop a hypothesis for the final experiments. Four different virtual reality models, representing four different kinds of virtual space, were navigated in C6 (CAVE facilities) by two human subjects. Results of the research in this direction have provided valuable understanding regarding the sense of presence in the virtual environment.

title	Making Understanding: Research in the application of virtual environments in the teaching of architectural design and technology
doi	https://doi.org/10.52842/conf.caadria.2005.093
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 93-101
summary	This paper describes how the application of interactive three dimensional computer modelling enables students of architecture to gain a comprehensive insight into how buildings are made. An intimate exploration of what can be, in the student’s perception, a lacklustre subject area is revitalized through the use of virtual building models and introduces the student to the potentials of this medium in communicating their own design work. In addition the published case studies are navigated as one would a web site which is a familiar and comfortable format for the student. Original working drawings and specification provided by architects are utilised in generating detailed three dimensional virtual models of the complete building along with larger scale detail studies of particular building components. The models are then animated or transferred to VRML format for publication within interactive case studies. The case studies may be accessed via the department server for use by staff during lectures and seminars or informally by the individual student.

title	Architecture and Biological Analogies
doi	https://doi.org/10.52842/conf.ecaade.2005.599
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 599-606
summary	The study described in this paper evolves within the larger context of a research aimed at inquiring into analogies between architecture and nature, and more specifically between architecture and biology. Biology is a recursive source of architectural inspiration due to the tight relationship between form and function, the natural balance of forces and the corresponding geometric solutions found in living beings. Roughly, one can classify historical analogies between architecture and biology into two main categories. The first tries to mimic biological forms and the second biological processes. The specific goal of the described study is to find how new technologies can redefine and support the process of constructing such analogies. It uses as a case study a tower project designed by the architect Manuel Gausa (ACTAR, Barcelona) called Tornado Tower because of its complex shape inspired in the frozen form of a tornado. Due to the geometric irregularities of the tower, Gausa’s team had difficulties in designing it, especially because solving the structural problems required constant redrawing. This paper describes the first part of the study which primary goal was to conceive a parametric program that encoded the overall shape of the Tornado Tower. The idea was to use the program to simplify the drawing process. This required a mathematical study of spirals and helices which are at the conceptual basis of the external structure and shape of the tower. However, the program encodes not only the shape of Gausa’s tower, but also the shapes of other buildings with conceptual similarities. Such class of shapes is very recurrent in nature with different scales and with different utilities. Therefore, one can argue that the program makes a mathematical connection between a given natural class of shapes and architecture. The second part of the study will be devoted to extending the program with a genetic algorithm with the goal of guiding the generation of solutions taking into account their structural fitness. This way, the analogy with genetic procedures will be emphasized by the study of the evolution of forms and its limits of feasibility. In summary, the bionic shape analogy is made by the generation of mimetic natural forms and a genetic process analogy starts with the parametric treatment of shape based on code manipulations. At the end the program will establish an analogy between architecture and biology both terms of form and process.

title	The Tower of Babel: Bridging Diverse Languages with Information Technologies
doi	https://doi.org/10.52842/conf.acadia.2005.184

summary	New digital tools or information technologies are providing the means for architects to realize unprecedented architectural creations. Unfortunately, the promise these technologies hold is far from their potential expression in the built physical environment. A contributing cause to this disjunctive state is the multiplicity of languages and knowledge sets employed by the various team members or actors engaged in a building project. From the cost models of the owners to the shop drawings of the fabricators, each actor views the project in terms specific to their individual discipline. In order to successfully engage the building process, these new technologies must account for this condition and develop means in which to span across traditional boundaries. This paper will examine the disjointed and fractured nature of the building project and identify opportunities for the deployment of information technologies to bridge boundaries, ultimately providing for and delivering architectural projects of unparalleled precedence. Specific aspects inherent to these technologies will be examined to understand where their application may benefit the building process. The key attributes this paper will focus on include: visualization tools, centralized database, cross discipline platform tools and novel forms of information representation. A case study of an architectural project will serve as the means in which to study the successful implementation of these attributes and their resulting impact on the design process and building project. This study will demonstrate how information technologies can be implemented within the multifaceted framework of conventional building projects to yield a project of unprecedented form.

title	Teaching Programming for and with Microcontroller-Enhanced Physical Models
source	International Journal of Architectural Computing vol. 3 - no. 1, 57-74
summary	As processes of use, interaction and transformation take center stage in various fields of design, electronic sensors, controllers, displays and actuators can significantly enhance the value of physical models. These technologies allow the development of novel computer interfaces for new kinds of interaction with virtual models, and in the future they can be expected to play an important role in the development of new types of active building components and materials for automated construction and dynamic runtime adaptations of inhabitable environments. However, embedding programmed logic into physical objects involves skills outside the traditional domains of expertise of designers and model makers and confronts them with a steep learning curve. The wide variety of alternative technologies and development tools available in this area has a particularly disorienting effect on novices. However, some early experiences suggest that mastery of this learning curve is easily within reach, given some basic introduction, guidance and support. To assist design students in acquiring a basic level of programming knowledge, better educational programming tools are still required. It is the intent of this paper to provide designers and educators with a starting point for explorations into this area as well as to report on the development of an educational approach to electronics programming called haptic programming.
