summary This paper proposes an interactive façade system capable of displaying the meaningful information extracted from this interaction using RFID. This façade system is a domain-specific, embedded system composed of three parts: an input device that employs RFID, a physical facade model that includes an output device and a microcontroller, and an application that consists of a middleware for the connection between the input and the output. The array of meaningful information derived from the input device is displayed as aesthetically flexible patterns created by Cellular Automata algorithms through the middleware. We expect that this facade will contribute to enhancing the building’s identity and to revitalizing desolate modem cities as an urban screen through the communication between people and buildings.

title An Interactive Cross-representational Data Modelling Approach for Early Stage Design Information
source Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 185-194
summary This presents a systematic approach to the organisation of early stage design information, and the associated interactions among various types of representation. Scene-level representations are introduced as the complement of traditional object-level representations in an integrated information system. A cross-representational approach is proposed. The advantage of this approach is in the support of both user-definable representations, and cross-representational manipulations, including organisational transformation, information filtering, information aggregation, and simulations, which are essential for designers to dig into raw data. A prototype program called NetworkBuilder is being developed in order to explore the approach.

title The shape of sound: Using mixed REALITIES to bridge music and architecture
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 494-500
summary There are structural and aesthetic components in architectural design that mirror the foundational components of musical compositions. In recent years, both architects and musicians have taken advantage of the advances in technology, allowing for new designs and compositions that would not be possible without computers. Mixed Realities, the merging of different reality worlds to create new environments where objects from these reality worlds can interact with each other in a real-time manner, is envisaged to become such technological platform bridging between space and sound. This paper discusses the interfaces of such bridging that can occur via Mixed Realities, the associated issues and possible outcomes of a Mixed Realities system that would allow for collaboration between architects and musicians.

title Production Method Of Accurated 3d Urban Models With Digital Photogrammetry
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 564-571
summary A convenient method for creating accurate 3D urban models without expensive survey equipment is developed by introducing digital photogrammetry. As a matter of logic, the 3D models for urban landscape simulations are expected to limit errors to several dozen centimeters. The proposed method is examined in order to reproduce the actual urban landscape and to provide accuracy that is sufficient to meet the theoretical requirement.

title Towards A New (Mapping Of The) City: Interactive, Data Rich Modes Of Urban Legibility
source Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 416-421
summary The modern metropolis is a vast environment replete with physical elements and complex overlays of information. The city historically has been represented as a discrete physical object; this allocentric view has become less and less useful as a method of meaningfully orientation and navigation. Today, the city is defined by technologies and flows of information that constantly change our perceptions. While it has always been true that symbolic and religious dimensions have had a place in our understanding of the city, the complex and transitory nature of the contemporary city requires a representation that is interactive rather than static. This paper presents proposals for new interactive modes of urban legibility: data space, based on the work of Bill Mitchell and Robert Venturi; virtual and physical city, established from the work of Christine Boyer and Bill Mitchell; multi-nodal, derived from the work of Tarik Fathy and Thomas Sieverts; and information flows, founded on the work of Melvin Webber. Each approach is introduced with a conceptual overview, nascent examples and a schematic proposal for a computer based urban visualization. Based on this study, we conclude that two necessary aspects of any urban visualization are interactivity and the combination of data and geospatial information. Interactivity is necessary because of the fluid nature of our experience and the diversity of individual intentions in the contemporary city. The combination of data and geospatial information is necessary because the geometry of the city had become less important as a reliable indicator of meaning.

title Proposition of a Model Using Parametric Operations as an Aid to the Creation of Architectural Forms
source Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 51-58
summary In the early stage of creation, the architect tests his working hypotheses by making many adjustments while designing. During the sketching phase, the existing modelling tools are not compatible with the iterative nature of this process. So the challenge lies in the definition of a model which will allow the whole creative process with its various coming and going during the phase of conception. In this article, we are going to define a data structure model allowing the simultaneous exploration of several possible solutions, which seems more in line with a creation process.

summary In the early stage of creation, the architect tests his working hypotheses by making many adjustments while designing. During the sketching phase, the existing modeling tools are not compatible with the iterative nature of this process. So the challenge lies in the definition of a model which will allow the whole creative process with its various coming and frowing during the phase of conception. We will illustrate this model by implementing a parametric operator allowing the action of folding. Its parametric specificity will enable the architect, in the design phase, to make the numerous moves alterations required to obtain an optimal shape.

summary This paper proposes a physical toolkit and a flexible software framework to simplify the design and exploration of interactive systems for multiple users, devices, and applications in a smart environment. The toolkit, called Elastic-Room, was designed as an infrastructure for interaction design, in which each device is a component that works collaboratively in the smart environment. The supporting software framework includes a dynamically reconfigurable intermediary which simplify the mapping of each device and also use simple protocol to broadcast information to each device. Finally, we demonstrate the Elastic-Room architecture by providing some implemented examples, which are organized in a prototype space of ubiquitous computing full of interactive components.

title Environment-Behavior Simulation: From CAD to BIM and Beyond

summary This paper describes our research on environment-behavior simulation and focuses on the modeling of built environments using Computer-Aided Design (CAD) and Building Information Modeling (BIM). Our environment-behavior simulation addresses the problem of predicting and evaluating the impacts of built environments on their human inhabitants. We present simulation systems comprising an agent-based virtual user model and building models created with CAD and BIM tools. We compare the use of CAD vs. BIM with two case studies for environment-behavior simulation, and describe the essential parts of modeling buildings for the simulation, including geometry modeling—how the building components are shaped, semantic modeling—what the building components are, and pattern modeling—how the building components are used by users. We conclude that a new extensible and pattern-embedded BIM system will be necessary to facilitate environment-behavior simulation.

title Building a Colour Image Database to Recommend Architectural Colour Scheme using Case-Based Retrieval Mechanism
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 103-109
summary The purpose of this study is to develop a digitized Taiwanese colour image database for architectural colour scheme in Taiwan. This paper uses adjectives to present each colour’s contribution to the colour image. The system uses the “colour difference formula” from the CIEDE2000 method, which calculates the difference between the two colour perceptions represented by the two given points. Using the “Group Nearest Neighbour” algorithm, the retrieval mechanism obtains a similarity measurement. This approach can help designers to know the meanings of colours and their associated colour images, which will help them develop the building image.

title Landscape Information Modeling

summary In this paper we report on a recently started PhD project in which we investigate the extension of the concept of “Building Information Model” (BIM) to the domain of landscape design. The potential benefits of BIM in the field of architecture have been reported many times (e.g., Ibrahim et al., 2004; Eastman et al., 2008; Abdelmohsen et al., 2011). However, in landscape design an information model in the way of BIM seems to be missing. Benefits of a Landscape Information Model would be (a) formalisation of knowledge in landscape design; (b) information model to support multiple participants in landscape design; (c) improved information exchange between landscape design, architecture, and urban design. In this paper we set out the basic outline of the research.

source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary This work is developed in the framework of urban design where we try to understand, to characterize then to qualify the environmental quality of urban open spaces along pedestrian walkways. So, we propose an analysis and a classification method applied to pedestrian walkways, taking into account their environmental characteristics. Analysis method is based on Discrete Wavelet Transform (DWT) in which we exploit the detailed version of the signal representing the evolution of a physical factor of environment along the walkway. This method leads to a segmentation of the signal. Then, a classification technique called Agglomerative Hierarchical Clustering (AHC) is performed to identify classes of walkways in terms of environmental features.

title Incorporating Principles of Bounded Rationality intoModels of Pedestrian Shopping BehaviorTheory and Example
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary The modeling and simulation of pedestrian behavior has been dominantly relied on rational choice models in which pedestrians are assumed to be capable of processing a large number of choice alternatives and trade off attribute utilities. In reality, however, pedestrian behaivor shows the evidence of bounded rationality. They simplify the decision problem by considering a limited number of factors as well alternatives, using heuristics to arrive at satisfactory as opposed to optimal choices. Incorporating principles of bounded rationality in pedestrian modeling will benefit the understanding of individual decision processes and planning practice. This paper proposes an approach that models the cognitive processes such as filtering factors, constructing preference structures, deriving heterogeneous decision heuristics, and selecting decision strategies. The approach is also exemplified through estimating the model on pedestrian store patronage behavior data, collected in a shopping center in Shanghai, China. The results show the estimated probabilities of usage of decision strategies and the sequences of factor search. Compared with the conventional multinomial logit models, the results indicate the statistical advantages of the new approach.

source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary Although it was proven by many field studies of office environments that complete thermal user satisfaction can only be achieved by setting the indoor climate to individual user preferences, open-plan offices do not support this requirement. In addition, irregular occupancy of such offices leads to suboptimal energy usage. This paper will show how the design of such offices can be supported by tools that integrate individual thermal user preferences and schedules into performance simulations to test and evaluate different partitioning structures, HVAC equipment, and control strategies in regard to satisfaction and energy consumption. A case study is used as demonstrator.

summary In this paper the possibilities of using computer software in creative searching of design ideas is analysed. At the basis of such psychological theories as Incubation, Synectics, Geneplore, Bisociation, Conceptual Blending, Visual Synectics the implementation of digital technologies in the idea searching – the main stage of design process – is presented. In all computer ‘metaphorisation’ methods presented in this paper pictures are treated as idea triggers. Designer generate the ideas of the form by use the pictures as triggers for free association or for metaphorisation. The two cases of implementation of these methods, which based on graphic transformations, will be presented.

title Animated Parametric Rapid Prototyping
source Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 897-904
summary This paper reports on the use of animation to enhance the observable range of choices in parametric rapid prototyping. Animation extends parametric rapid prototyping in three ways. First, it is used to reveal dynamically a set of possible forms from which to pick out one that may best serve a particular design project. That is, by animating the parameters that drive the geometrical model, we can visualize the continuum of alternatives that lie between specific key-framed settings of an architectural form. Second, animation can be used to pre-visualize a series of geometrical constructions for transforming a relatively raw three-dimensional form into one that satisfies the demands of a completed architectural project. Third, animation can be used to pre-visualize transformations of a given structure based on parameters set to adapt to varied conditions. In each case study, physical models were assembled through CNC fabrication.
