summary	The design paradigm has shifted from addressing geometric masses and social spaces to integrate a whole new set of variables and criteria evolving from the environmental aspect of the design. Architectural design is confronting a mounting challenge with the ever-growing complexity of design concepts and the increasing pressure to incorporate aspects of energy preservation and sustainability. Such challenge is clearly noted and sensed within the pedagogical realm. There are many calls to bridge the gap through assisting design students to assimilate environmental analysis data in their design and decision making process. This paper presents a framework for a proposed method and relating tools aiming to utilize games technology with multi-agent systems and data mining techniques to assist design students and untrained professionals in comprehending various aspects of environmental design, with guidelines to incorporate these aspects in their design iteration process.

title	Designing a Systematic Experiment to Investigate the Effect of Ambient Smell on Human Emotions in the Indoor Space; Introducing a Mixed-Method Approach
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_20

summary	Studies have indicated that built environments affect all aspects of human life such as emotion, perception, behavior, health, and well-being (Cooper et al. 2011). Built environments are formed from the combination and juxtaposition of visible and invisible environmental variables. In recent years, common techniques such as virtual reality, augmented reality, digital twins, and artificial intelligence have enabled researchers in the field of architecture and urban design to simulate environmental conditions to investigate the impacts of environmental variables on humans. However, the studies conducted in this field of human comfort are mostly focused on the impact of environmental variables such as form, temperature, humidity, and sound, and in fewer studies, up-to-date methods and technologies have been used to simulate and investigate the impact of smell on humans. Most of the studies that have investigated the effect of ambient smell on humans, carried out in the discipline of architecture and urban design, have used traditional tools and methods (questionnaire, interview, observation) rather than advanced technology and tools drawing on neuroscientific knowledge and technique to measure the effectiveness of the ambient smell on human. They have used unmasked scents or real-world environments rather than being able to simulate environmental conditions. This article highlights the significance and necessity of employing simulation methods to investigate the impact of environmental smells on humans. Additionally, it presents the methodology of an experiment for studying the effect of indoor environment smells (with a case study of an office environment in the initial phases) on human emotions, utilizing a mixed-method approach. Analysis of some parts of the data from this experiment showed that exposure to the fragrance of the jasmine flower pleasant (flower) and the odor of the rotten orange peel (unpleasant) can cause changes in the electroencephalography (EEG) power across different bands among participants.

title	InfoMatters, a multi-agent systems approach for generating performative architectural formations
source	International Journal of Architectural Computing vol. 9 - no. 3, 205-222
summary	The research paper exemplifies upon a computationally intensive inter-disciplinary research driven design investigation into spatializing the relationship between digital information and physical matter. Focusing on the development of architectural scale urban inserts, the design-research work operates on the intersection of information technology, environmental design, architecture, and computer aided manufacturing domains.The research framework revolves around developing a seamless integration of the aforementioned disciplines in order to establish iterative simulation driven methodologies for generating bottom-up sustainable architectural formations. This is achieved by establishing parametrically driven relational linkages between differential data sets (environmental, social, topological, material etc), which formulate the context (both global and local) within which the proposed project has to be designed. A selforganizing multi-agent system based simulation methodology for generating resultant spatial formations, in time, based on the impacts of the parametric relationships between the aforementioned data sets is eventually embarked upon. This implies, understanding the site as a dynamic information field within which interdependent ecology of agents (representing typology of people, program, structure, speed, desired social interaction etc) with multi-level relational affinities amongst each other as well as the dynamic urban information field. The resultant self-organized multi-agent formations are iteratively mined for identifying logical three-dimensional structural patterns or subjected to programmatic and environmental need driven additional layer of structural simulation with pre-embedded material restraints. An optimized system of multi-performative components that not only populates but also serves as an integrated structural + skin system of the results obtained from the agent based simulations (based upon the degree of inclusion/exclusion of parameters such as the amount of light, sound, wind etc) is subsequently generated. These experimental projects attained the status of self-evolving ecologies of multi-dimensional agents with embodied behavioural profiles, thus providing engaged, highly interdependent design by simulation outputs. The outputs showcase a dynamic system's driven approach towards sustainable design by stressing upon the idea of cohesively binding information and material systems from the very beginning of the design process. Such approaches help in reducing post-optimization of built form and consequently allow for rational understanding of performance criteria and its impact on formal articulations throughout the design process.

title	Nimble Urban Dwellings: Re-enabling Permanent Impermanence
doi	https://doi.org/10.52842/conf.ecaade.2011.635
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.635-644
summary	This paper considers an evolutionary type of urban dwelling—where permanent impermanence may be a preferred state for those who favor nimble dwellings that are better able to respond to change. These changes may be socio-economic, geographic, technological, environmental, cultural, employment-related, or simply the result of unanticipated disruptions. The goal of this research is to describe a system which enables improved functionality, flexibility, and desirability for modest, yet highly diverse, urban dwelling solutions based upon an evolving, open-source system of digital design standards. Given that consumer product designers have, for more than a decade, successfully utilized digital technology to design and produce highly desirable products, this paper asks whether urban dwellings might benefit from concerns more in keeping with those of consumer products.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design
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. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

title	Using Geo-Located Augmented Reality for Community Evaluation
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. 701-720.
summary	Conventional practices of two-dimensional representation of three-dimensional objects remain an impediment to end-user engagement in participatory urban design. An alternative is to harness geo-located augmented reality (GAR) technology to embed life-sized virtual three-dimensional images at the actual site of proposed interventions. This format offers closest to real-life visualizations for end-users, enabling them to firstly comprehend and then express feelings concerning future proposals. This paper presents an iPhone web-app that capitalizes on the Layar browser’s GAR interface to tip the economies of scale in favor of intimately attached users of public space, rather than often remotely detached clients and their commissioned designers. Walk-around virtual images of public space designs can be viewed and commented via iPhones by the public. It further allows users to display their own ideas as alternatives, thus in effect serving as an instrument for advancement of CAAD-enabled participative environmental design in general and the idea of reclamation of authorship of public space in particular. This paper briefly describes the development of a prototype, including its preliminary evaluation, and then highlights a study to determine the 3D rendering performance parameters of GAR technology, as the core component of the idea. The paper concludes with a discussion of future implications.

title	The sensitive tower: Architectural and urban design education faced with fragile metropolitan ecologies
doi	https://doi.org/10.52842/conf.ecaade.2011.581
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.581-588
summary	Neighborhoods that are still outside the market target can find alternative ways of re-development. Therefore, it is necessary to design architectures compatible with their fragile ecologies. This research benefits from a previous study where we tried to observe the evolution of the uses of buildings and ways of living faced with changes in environmental conditions in a given urban context. Increased automobile traffic has led to changes in the use of residential spaces whose function was gradually replaced by commercial activities. Making use of graphic-oriented interpretation of urban ambiance and landscape analysis methodology applied to the design of different floor levels, this paper aims to introduce the concept of sensitive tower defined on the basis of observations made in our post-occupancy survey as a teaching strategy for the design studio faced with the current challenges of the contemporary metropolis.

title	Real-time porosity: Combining a computer game engine with environmental sensors to better understand pedestrian movement in public/private space and in real-time
doi	https://doi.org/10.52842/conf.caadria.2011.229
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 229-238
summary	This paper describes the theoretical context, design, implementation and evaluation of a novel method for understanding pedestrian movement in public/private space. It examines the pedestrian counting and tracking methodologies of Space Syntax and proposes an alternative methodology that links sensors embedded in real-world environments and carried by pedestrians with an environment and avatars in a contemporary computer game. In this way observers are able to closely trail pedestrians without affecting their decision making. Results from a field trial are presented where the sensors and computer gaming technology were tested within a challenging real-world environment.

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.

summary	Driven by advances in building and information technology and accelerated by the tumultuous period of global economic restructuring that commenced in 2008, architecture and interior design practice is today confronted with the necessity of fundamental change. According to the “Building Futures” group at the Royal Institute of British Architects and US-based “Design Futures Council,” both of which this past year published studies on this very topic, a great deal depends on what happens in China and other emerging markets, where many European and US firms now have offices. And that is not only because these are the most vibrant markets for architecture and design services, but also because the demands placed on practitioners in these markets are fundamentally changing the way buildings are designed and delivered, at home and abroad. Both studies suggest that all sectors of the A/E/C industry will face increasingly fierce competition that will, of necessity, force practices large and small to compete less on cost and more on value. In the very near future buildings and their interiors will be valued almost entirely based on performance—economic, cultural, environmental—and only those firms able to create these and other forms of added value will survive. Disruptive technologies like building information modeling and integrated product delivery will enable all firms, even those competing solely on the basis of cost, to design better buildings and deliver them more efficiently. But in such a fiercely competitive global marketplace, efficiency alone will not be enough to guarantee market viability. The real differentiator will instead be design.

title	Toward Responsive Atmospheres: Prototype Exploration through Material and Computational Systems

summary	The Stratus Project is an ongoing body of design research investigating the potential for kinetic, sensing and environment-responsive interior envelope systems. The research emerges from a consideration of our attunement to the soft systems of architecture – light, thermal gradients, air quality and noise – paired with a desire to develop and prototype envelopes that not only perform to affect these atmospheres, but also to promote continual information and material exchange, and eventually dialogue, between occupant and atmosphere. Stratus v1.0 included the construction of a modest prototype using simple open source technologies, aimed to explore the formal, operational and technological possibilities, as well as potential operability and control conflicts, as part of the first phase of thinking around these questions. It deploys a distributed approach to structural, mechanical and communications systems design and delivery, where localized response is prioritized. The project works to reclaim the environmentally performative elements of architecture – in this case, specifically, interior mechanical delivery and interface systems – to within the purview of the discipline, as territories of material, formal, technological and experiential innovation and exploration. This paper will describe both the development of the current prototype as well as future research and investigation trajectories. The Stratus Project begins by situating itself at the crossroads of the disciplinary territories of architecture, technology, environmental control and cybernetics. Through the use of computational technologies and in collaboration with researchers in the fields of computer science, mechanical engineering and materials science, this project aims to advance the development of responsive environmental design and performative building skins.

summary	Teaching about cities and planning involves complexities of understanding urban development in space and time, evolution and transformation of cities, urban politics, actors and stakeholders. Delivering efficient ways of teaching, is very important for educators, particularly among lecturers at universities who work with urban planning and design. Games can be used as educational tools and role-playing games can capture the political struggle of different actors and stakeholders involved in planning processes. Games can enable students to experience urban development and take roles of different actors and stakeholders in the planning and development processes and practice the art of negotiations in urban politics. Two educational games were written for the planning courses at KTH Royal Institute of Technology, Sweden. Since 2011, 17 games were played in different courses. Data from the evaluation forms was collected on 14 games and 277 students answered questions. This paper analyses the evaluation forms and the comments of the students who took part in the games and discusses gaming as an educational tool. The experiences with role-playing planning games are very positive. These ratings occurs consistently in each game that was played with very small variations.

title	Behavior-based Computational Design Methodologies: Integrative processes for force defined material structures
doi	https://doi.org/10.52842/conf.acadia.2011.082
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 82-89
summary	With the introduction of physics-based algorithms and modeling environments, design processes have been shifting from the representation of materiality to the simulation of approximate material descriptions. Such computational processes are based upon enacting physical and material behavior, such as gravity, drag, tension, bending, and inflation, within a generative modeling environment. What is often lacking from this strategy is an overall understanding of computational design; that information of increasing value and precision is generated through the development and iterative execution of specific principles and integrative mechanisms. The value of a physics-based modeling method as an information engine is often overlooked, though, as they are primarily utilized for developing representational diagrams or static geometry – inevitably translated to function outside of the physical bounds and parameters defined with the modeling process. The definition of computational design provides a link between process and a larger approach towards architecture – an integrative behavior-based process which develops dynamic specific architectural systems interrelated in their material, spatial, and environmental nature. This paper, focusing on material integration, describes the relation of a computational design approach and the technical framework for a behavior-based integrative process. The application is in the development of complex tension-active architectural systems. The material behavior of tensile meshes and surfaces is integrated and algorithmically calibrated to allow for complex geometries to be materialized as physical systems. Ultimately, this research proposes a computational structure by which material and other sorts of spatial or structural behaviors can be activated within a generative design environment.

summary	This paper proposes Buckminster Fuller’s concept of pattern integrity as a context for understanding computational techniques in environmentally responsive design. We argue that successful integration in this context requires a continuous design medium that allows for heterogeneous, mutable techniques and models. This model of integration is demonstrated by reference to a current project for a large canopy structure in Singapore with specific focus on issues of environmental mediation, object-oriented programming for CAD environments, and functional programming techniques within parametric modeling systems. We discuss the applicability of these novel integrative approaches to wider problems in computational design.

summary	This paper presents continuing research on responsive systems in architecture; the ability of architectural systems to change certain properties in response to their surrounding environmental pressures. While doing so, it shifts from current and past examples of mechanical approaches of adaptation, towards biological paradigms of seamless material integration. Looking at biological mechanisms of growth and focusing on the material make-up behind them, the research proposes the exploration of material systems in a two-fold interrelated manner: firstly, through passive material systems of variable elasticity, and secondly through the embedment of smart materials with shape-changing properties. The combination of the two is aiming at architectural systems of functional versatility.Through an interdisciplinary approach, the paper examines the following questions: Is it possible to envisage structures that share the principles of adaptation and response of living organisms? What are the technological challenges faced when designing self-actuated responsive interfaces? Which is the conceptual framework for understanding and investigating complex adaptive and responsive systems? By exploring and synthesizing theories and tools from material science, bioengineering and cybernetics the aim is to inform architectural interfaces able to enhance interconnectivity between the man-made and the natural. Focusing on the self-organization of material systems the intention is to suggest architectural interventions, which become sub-systems of their ecological milieu. The emphasis therefore is placed not on architectural formalism, but on how we can define synthetic environments through constant exchanges of energy, matter and information.

summary	Designers have always assembled materials to form purposeful connections between ideas and spaces, uniting the height of human thought with the great ability of people to shape the world with their hands and tools. People have understood this opportunity and used it to inform the material investments that they make in buildings.When reflecting upon the past ten or so years of practice it is clear that some methodologies have matured. Professionals, academics and students have found new ways to connect thinking and doing. These connections have a different flavor and tend to feel more analytical to those once used. Previously internalized decisions are being made increasingly explicit by a generation of designers that has found a more meaningful overlap between the theories and procedures of design. The methods they use are visual, analytical, as well as intuitive, and encompassed within a whole gamut of tools such as Grasshopper, Ecotect, Digital Project and Generative Components. All of these tools provide opportunities for designers to inquisitively explore alternative formal, spatial and environmental relationships. The opportunities that are brought by increasing externalization are important. Design is at once turning away from its focus on the end result, be it a building or an interior, and toward a renewed interest in the design process itself. Brought about by encapsulating design principles into self-made tools, this shift has enabled families of formal outcomes rather than singular instances of ‘pure’ architecture. These multiple, equally valid, formal outcomes disrupt more traditional measures of formal legitimacy and help move architects toward more relational understandings of space, time and environment.

title	Use of a Knowledge Model for Integrated Performance Evaluation for Housing (re)design Towards Environmental Sustainability: A Case Study
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. 281-296.
summary	This paper focuses on the development of a knowledge model in the context of energy efficiency and indoor climate interventions, their impacts on each other and on architectural design preferences (for instance architectural expression or any spatial functionality aspect) via an existing house case study. In addition, it attempts to discuss how this type of model can be a reference for a decision support tool and be applied to the (re)design of dwellings. The model is considered to provide an integral knowledge base for the design professional both to evaluate existing designs and to use it as a support during design and decision making in order to reach the best possible solution, with optimal performance in terms of indoor comfort, energy-efficiency and overall design performance. In other words, its aim is to enable the assessment of the performance of the end result with respect to design choices, beforehand. In this paper, design performance is modeled by means of fuzzy logic operations. It is a method to deal with subjective and vague requirements such as low energy consumption, low overheating risk, high comfort, etc. The method of intelligent information processing is explained and a partial application is presented.

summary	This paper presents a research developed by a multidisciplinary team looking into the use of Topological Optimization and its integration to collaborative design platforms in early stages of design processes. The interest of the experience is focused on how Evolutionary Structural Optimization (ESO) models can be further integrated into parametric design software for the definition of adaptable components in response to environmental and architectural criteria. This research explores platforms and processes for the collaboration between software development, structural engineers and architects in early stages of design as a possibility to relate the potential of computational processes with the definition of design criteria involving architectural, structural and environmental parameters.

title	Analyzing the Ventilation Performance of Tropical High Density Residential Precincts using Computational Fluid Dynamics
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. 351-366.
summary	Major cities in the world are getting bigger as they continue to grow to cater for more population increase. These cities normally forced the urban planning to go high density. In the tropical context, high density cities like Singapore and Hong Kong do not have the luxury of space to go low rise and compact. These cities have to build to the floor area ratio of 4 and above to cater for the population. Their only solution is to go up, as high as possible, to the extent that the natural wind flow pattern will be altered, which brings environmental impact to the people. This is generally not good since wind flow helps to maintain the thermal comfort of the people as heat and pollutants are being channeled out of the city to avoid Urban Heat Island effect. In the tropical context, wind flow is crucial to maintain people‚Äôs comfort as the temperature is generally very high from the exposure of the sun for the entire year. Studies have shown that wind flow plays the most significant part in maintaining human comfort despite exposing to direct sunlight in the tropics. Therefore, wind flow analysis is extremely crucial to make the design sustainable and energy efficient, as people will not have to depend on mechanical ventilation to compensate for the lack of wind flow. Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment apart from wind tunnel tests. The availability of more powerful hardware for the mainstream computer users as well as the lowering costs of these computers made CFD more possible to be adopted in the design world today. This also means using CFD in the design process, especially to analyze the impact of the design to the current site conditions and annual wind patterns will help the new design to be more responsive to the site. The interest of this paper is to analyze the high density typologies to see how well they respond to the local wind flow pattern. A typology is considered acceptable when the wind flow going through the site is still maintaining acceptable wind speed. This means it does not block off the wind and create stagnant spaces. Different designs generate different typologies which will respond differently to the wind pattern. The study aims at comparing the local high density typologies in terms of their response to the wind. Changes to a typology can be explored too to see if the performance will be different. For a typology which is considered a total failure in terms of response to wind, it may improve its performance if the orientation is altered. The CFD software can also parametrically respond to the changes of the typologies‚Äô dimensions. This is helpful to see how much more a typology can still be performing well before failure by increasing the floor area index. The easiest way to do this is to pump up the building height. In conclusion, designing in response to wind is extremely important as it is more sustainable and responsive to Urban Heat Island effect. A design which responds well to the wind patterns will help save cost of cooling load and fan expenditure. The people will also be more willing to use the outdoor spaces which will as a whole generate more vibrant city spaces. As a result, a high density city with huge population count can still enjoy good thermal comfort if the general urban planning and design respond well to wind.

summary	For most architects and engineers, the idea of optimizing a building’s design in relation to its location is so ingrained as to be a reflex. Still, most building professionals have a difficult time making the conceptual and practical leap to the notion of performance-based or “adaptive” buildings. We call these adaptive buildings because they can adapt their shape and function in realtime to environmental changes. This field remains far less developed than other areas of practice, but the logic of adaptive performance — which is time-based, responsive, and dynamic — is compelling. Buildings that continuously attune their configurations in accordance with changing environmental conditions use less energy, offer more occupant comfort, and feature better overall space efficiency than static buildings.
