summary	This paper presents a design process efficiently involving parametric design, realistic physical simulation and rapid-prototyping fabrication for contextual shape adaptation. This case study focuses on lighting simulation for the specific problem of solar energy harvesting. Inspired by the phototropic mechanism, the ability of plants to grow according to the availability of light, an innovative design technique is defined, taking its root in the morphogenetic design school [Hensel, 2004].

title	MxR: A Physical Model-Based Mixed Reality Interface for Design Collaboration, Simulation, Visualization and Form Generation
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, 464-471

summary	MxR—pronounced “mixer”—is a Mixed/Augmented Reality system intended to support collaboration during early phases of architectural design. MxR allows an interdisciplinary group of practitioners and stakeholders to gather around a table, discuss and test different hypotheses, visualize results, simulate different physical systems, and generate simple forms. MxR is also a test-bed for collaborative interactions and demonstrates different configuration potentials, from exploration of individual alternatives to group discussion around a physical model. As a MR-VR transitional interface, MxR allows for movement along the reality-virtuality continuum, while employing a simple tangible user-interface and a MagicLens interaction technique.

title	Agent-Based System for Modeling User Behavior in Shopping Malls
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 635-642

summary	Agent-based systems are being used as decision support systems for solving architectural design problems. Usually in design phase, user behavior is ignored by the designers. Therefore, after the construction, the users face difficulties in emergency situations and in daily usage. As a result, buildings become insufficient to respond to users’ needs and design goals of the building itself. Before construction, ability of testing the interactions between the building and its users is particularly important to solve the problems in early phases of the design. Hence, to design a building that functions better in certain situations and time loss decreases in the design process. For these reasons, the aim of this study is to develop a model to simulate users in shopping malls.

summary	This paper attempted to develop a simulation model of residents’ firefighting activity against coseismic fire spread using multi-agent system. The developed model was applied to a case study area. In the application, the simulations were carried out to the existing area and eleven cases of the assumption (virtual conditions) of the area where are implemented various non-physical and physical measures. As a result, the measures with only physical and haphazard multitude of measures did not show a remarked effect of disaster prevention performance. And, it is confirmed that the model can visually, dynamically and quantitatively output results. From these outputs, the possibility of contribution for enhancing residents’ awareness and drafting a plan of disaster prevention was confirmed. However, there are still some problems to be solved for the practical use of the model.

summary	Branching occurs in natural systems for functional reasons. However, the branching logic for each specific system is quite different due to environmental and mathematical factors. In the computation of branching systems, these mathematical factors can be incorporated quite easily into the coding of each system. However, it is the environmental components that must be given further consideration in the simulation of these natural systems. Through the engine of genetic algorithms based on evolutionary developmental theory, the specific logics observed and analyzed in branching patterns of river systems, trees, and insect tracheae can be simulated and optimized in a digital environment.

title	The Urban Decision RoomApplication and Evaluation of an Urban Management Instrument

summary	The Urban Decision Room (UDR) should be placed in the tradition of urban design and planning discipline that is taught, and into which research is carried out, at the Faculty of Architecture at the Delft University of Technology. The UDR was developed at the faculty as one of the new design and planning methods with its own specific features. The UDR is specifically aimed at decision-making processes in the practice of urban planning, and particularly at complex urban area development projects. The background to the design enables the UDR to support planning decisions that are made at urban planning element level. The participants in the interactive UDR sessions are asked to provide concrete solutions for urban planning design problems (in terms of preferences for particular functions, number of plots, etc.) and to enter them in a simulation model. A computer network is then used to calculate the common solution space of all the proposals, which is then projected onto a central screen. This outcome generally provides the basis for further discussions and negotiations, after which another round as described above can be held. The paper first focuses on the background and the main features of the UDR system. Secondly, the decision-making issue and a description of a specific Urban Decision Room model, the UDR Heijsehaven will be explained. Thirdly the structure of, and the experiences from, the experimental sessions with the Urban Decision Room Heijsehaven are described. After that the results of the evaluation of the UDR system by participants is presented and finally the follow-up assignment for the UDR system is carried out.

summary	“Why do we have to change? We’ve been building buildings for years without CATIA?” Roger Norfleet, a practicing architect in his thirties poses this question to Tim Quix, a generation older and an expert in CATIA, a computer-aided design tool developed by Dassault Systemes in the early 1980’s for use by aerospace engineers. It is 2005 and CATIA has just come into use at Paul Morris Associates, the thirty-person architecture firm where Norfleet works; he is struggling with what it will mean for him, for his firm, for his profession. Computer-aided design is about creativity, but also about jurisdiction, about who controls the design process. In Architecture: The Story of Practice, Architectural theorist Dana Cuff writes that each generation of architects is educated to understand what constitutes a creative act and who in the system of their profession is empowered to use it and at what time. Creativity is socially constructed and Norfleet is coming of age as an architect in a time of technological but also social transition. He must come to terms with the increasingly complex computeraided design tools that have changed both creativity and the rules by which it can operate. In today’s practices, architects use computer-aided design software to produce threedimensional geometric models. Sometimes they use off-the-shelf commercial software like CATIA, sometimes they customize this software through plug-ins and macros, sometimes they work with software that they have themselves programmed. And yet, conforming to Larson’s ideas that they claim the higher ground by identifying with art and not with science, contemporary architects do not often use the term “simulation.” Rather, they have held onto traditional terms such as “modeling” to describe the buzz of new activity with digital technology. But whether or not they use the term, simulation is creating new architectural identities and transforming relationships among a range of design collaborators: masters and apprentices, students and teachers, technical experts and virtuoso programmers. These days, constructing an identity as an architect requires that one define oneself in relation to simulation. Case studies, primarily from two architectural firms, illustrate the transformation of traditional relationships, in particular that of master and apprentice, and the emergence of new roles, including a new professional identity, “keeper of the geometry,” defined by the fusion of person and machine. Like any profession, architecture may be seen as a system in flux. However, with their new roles and relationships, architects are learning that the fight for professional jurisdiction is increasingly for jurisdiction over simulation. Computer-aided design is changing professional patterns of production in architecture, the very way in which professionals compete with each other by making new claims to knowledge. Even today, employees at Paul Morris squabble about the role that simulation software should play in the office. Among other things, they fight about the role it should play in promotion and firm hierarchy. They bicker about the selection of new simulation software, knowing that choosing software implies greater power for those who are expert in it. Architects and their collaborators are in a continual struggle to define the creative roles that can bring them professional acceptance and greater control over design. New technologies for computer-aided design do not change this reality, they become players in it.

title	Kanban as a Supporting Tool for the SUSTAINABLE Design and Operation of Smart Buildings The potential of the Toyota Production System in 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. 68-74
doi	https://doi.org/10.52842/conf.caadria.2008.068
summary	This paper describes the translation of the process management tool ‘Kanban’ and its adjacent Toyota Production System into an architectural design supporting tool in the context of computer integrated buildings. The triggering question is: ‘How can architects handle requirements and services of ubiquitous computing in relation to their cursory knowledge about networked services and its unpredictable future development?’. The paper develops a system called ‘Ubicomp-Kanban’ based on the characteristics Toyota Production System. It is suitable for both design and operation of binary networked services in built environment in selected architectural scales and selected functions. The application of the system allows more precise planning and resource optimized operation of academic buildings. The paper does not intend to set up a new approach for building information models (BIM).

title	Rapid Agent Based Simulation of People Flow forDesign of SpacesAnalysis, Design and Optimisation
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 paper presents a novel static-dynamic network based people flow simulation model applied to design optimisation of circulation spaces within buildings and urban areas. In the current state of art the majority of existing people flow simulation models are driven by analysis rather than design. This is fine for simpler, evacuation type scenarios where a single or a few analyses runs are sufficient to determine the evacuation time. For more complex scenarios such as crowd circulation with complex multi-directional flow, one is as interested in the sensitivity of various design and stochastic behavioural parameters, so the rapid modelling simulations together with design capability become important. This paper presents a simplified network based people flow model that enables rapid simulations and therefore iterative design optimization of circulation space. The work integrates the techniques of graph-theory based network analysis with an origin-destination matrix model of crowd flow, to provide a rapid, parametric model. The resulting model can be analysed in a static as well as dynamic state. In the static state, the model analyses space based on connectivity of nodes, superimposed with the origin-destination matrix of population to provide valuable information such as footfalls, density maps, as well as quasi-static parameters such as mean flow rates. In the dynamic state, the model allows time-dependent analysis of flow using a detailed agent based simulation that also incorporates dynamic route-choice modelling, agent behaviours and interaction, and stochastic variations. The paper presents the integrated modelling technique and its implementation into simulation software SMART Move.

summary	The basic principles, methods, and digital tools for the analysis of room acoustics are the topic of this paper. Students have been using these analysis and simulation tools during a seminar at Stuttgart University to systematically investigate acoustical situations. Additionally to lecturing on the underlying physics of room acoustics we were trying to convey the impact of geometry on room acoustics and therefore the impact of room acoustics on shapes in architecture. This paper describes the implementation of a real time simulation module for room acoustics within our Virtual Reality System.

summary	This paper presents the validation of an office utilisation model for the research project called “User Simulation of Space Utilisation (USSU)”. The result of this research is a system that can be used for analysing and evaluating the space utilisation of a building for any given organisation. A system for building usage simulation that produces data about activities of members of an organisation can substantially improve the relevance and performance of building simulation tools. This is relevant for engineering domains as well as for architects to evaluate the performance of a building design. For a thorough evaluation of the system an experiment was executed for assessing its predictive quality in the context of a real building, organisation and actual human behaviour; this experiment was executed using RFID technology. The result of the experiment was observed data about the space utilisation of the selected organisation. These data were compared with the space utilisation predicted by the USSU system to evaluate the simulation model. The validation of USSU showed that there were no significant differences between the predicated and observed activity behaviour. As a consequence, the output of USSU is considered to be valid.

doi	https://doi.org/10.52842/conf.acadia.2005.200
summary	This paper presents the innovative architectural design concept, which is to integrate the new material and technology into the building design to achieve the thermal comfort and at the same time reduce the energy consumption of the building by making use of the renewable energy, including solar and wind energy. The system is developed based on the idea of regional thermal comfort in building. The advantage of the system is the environmental friendly approach, costless operation, reliability, flexibility, scalability and adaptability for the integration to the building design. With the design concept, we tried to do two application designs in two virtual sites. One is a badminton court for the 2008 Beijing Olympic Games and the other is a cooling pond in a shopping mall. We will introduce how computational simulation can contribute to the prediction of the performance of the design. We will also discuss how the computation simulation can help in the design optimization process. Through the development of the new design integration of the material to the building, we would like to feedback to the material industry to encourage further collaboration and development in the material enhancement, so that both industries and the society can benefit from the advancement.

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.

summary	Designers; architects and artists in general always proceed with one crucial goal in their mind when they design: to be able to materialize the scheme in their mind. There are some tools that can help designers to test their design to see if it will be successfully constructed or functioned as close as possible as the way they imagined or expected; visual simulation models in digital environments of the designs are such important tools for architectural design process, but these models does not provide enough data to determine the design’s applicability. Therefore, the need of a tool that would work with the designer in order to determine the possibility of whether the design could be built or not as the way designer imagined, is vital.

title	An Energy Centric Approach to Architecture: Abstracting the material to co-rationalize design and performance

doi	https://doi.org/10.52842/conf.acadia.2008.072
summary	This paper begins by exploring matter as an aggregated system of energy transactions and modulations. With this in mind, it examines the notion of energy driven form finding as a design methodology that can simultaneously negotiate physical, environmental and fabrication considerations. The digital workspace enables this notion of form finding to re-establish itself in the world of architecture through a range of analytic tools that algorithmically encode real world physics. Simulating the spatial and energetic characteristics of reality enables virtual “form generation models that recognize the laws of physics and are able to create ‘minimum’ surfaces for compression, bending [and] tension” (Cook 2004). The language of energy, common in engineering and materials science, enables a renewed trans-disciplinary dialogue that addresses significant historic disjunctions such as the professional divide between architects and engineers. Design becomes a science of exploring abstracted energy states to discover a suitable resonance with which to tune the built environment. ¶ A case study of one particular method of energy driven form finding is presented. Bi-directional Evolutionary Structural Optimization (BESO) is a generative engineering technique developed at RMIT University. It appropriates natural growth strategies to determine optimum forms that respond to structural criteria by reorganizing their topology. This dynamic topology response enables structural optimization to become an integrated component of design exploration. A sequence of investigations illustrates the flexibility and trans-disciplinary benefits of this approach. Using BESO as a tool for design rather than purely for structural optimization fuses the creative approach of the architect with the pragmatic approach of the engineer, enabling outcomes that neither profession could develop in isolation. The BESO case study alludes to future design processes that will facilitate a coherent unfolding of design logic comparable to morphogenesis.

summary	Flexible mass customization of buildings is still in its infancy. Current systems for the automated support of owner-driven configuration management are limited with regard to the degree of freedom they offer to end-users. In this paper we present and discuss a constraint definition and verification system that allows the architect to specify boundary conditions within which the client can vary the design. The required constraint grammar is presented and applied to a real-world building code. A 2D floor plan prototype is tested to reveal the methodological and technical issues to be solved to make a step forward.

title	Elemental Methods for Integrated Architectures: Experimentation with Design Processes for Cable Net Structures
source	International Journal of Architectural Computing vol. 6 - no. 4, 453-475
summary	Tension active systems are compelling architectural structures having an intimate connection between structural performance and the arrangement of material. The direct flow of structural forces through the material makes these systems attractive and unique from an aesthetic point of view, but they are a challenge to develop from a design and an engineering perspective. Traditional methods for solving such structural systems rely on both analog modeling techniques and the use of highly advanced engineering software. The complexity and laborious nature of both processes presents a challenge for iterating through design variations. To experiment with the spacemaking capabilities of tension active systems, it is necessary to design methods that can actively couple the digital simulation with the analog methods for building the physical structure. What we propose is a designer-authored process that digitally simulates the behaviors of tension active systems using simple geometric components related to material and structural performance, activated and varied through elemental techniques of scripting. The logics for manufacturing and assembly are to be embedded in the digital generation of form. The intention is to transform what is a highly engineered system into an architectural system where investigation is as much about the determination of space and environment as it is about the arrangement of structure and material.

summary	The first part of the paper is centred on the phenomena of urban growth, in order to set the rules for a sustainable scenario of urban development. Then we enter the core of the paper that is the comparison of models. For each of the three compared models, we describe its main theoretical characteristics, the chosen parameters, and the obtained results. In section 6, heterogeneity of the produced results is discussed, and we highlight the points of interest and the lacks of the three models. Here we show that results we obtained feed debates about urban growth management. Finally, concluding remarks at the end of the paper address the general topic of the evaluation of the quality of simulation results.

It proposes the use of agent-based crowd simulation software on a mid-scale urban planning level for design evaluation. The information on agents’ movements is noted in standard raster images. The results are maps that are easy to understand. These maps show movement paths of the agents and density and give further conclusion on bottlenecks in planning contexts. Key measures, like the occupant movement in a given district, until now relied greatly on empirical knowledge or data that could be only gathered after an urban design had become built reality. Our method focuses on the adaptation of common software technology that is originally situated in film and TV productions. A practical workflow shows how our method can be easily integrated in daily design tasks.
