title	Wind sensing with real-time visualisations for Designers - An approach to understanding wind phenomena for pedestrian comfort using low cost wind sensors
doi	https://doi.org/10.52842/conf.ecaade.2014.1.165
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 165-171
summary	The evaluation of a low-tech wind sensing platform for urban aerodynamic simulations relevant to pedestrian comfort. In this paper, the wind canyon effect is simulated with two different building morphologies. The platform provides conceptual knowledge of the dynamics in wind relevant for designers, architectural practitioners and students of design. Low-cost hot wire anemometry is utilised for the design of an Experimental Fluid Dynamic (EFD) wind sensing network interface. This paper explores the validity of the sensing platform for a new approach for non-wind engineers to gain a better understanding of the dynamics of wind. The influence of real-time feedback from quantified wind on the understanding of wind phenomena for non-wind engineers is discussed and compared with post analysis data. It was found that real-time quantified feedback from wind intrigues and stimulates the intuitive notion of wind dynamics through discussion, however post analysis remains critical to evaluate building design performance.

title	Computing the Urban Block - Local Climate Analysis and Design Strategies
doi	https://doi.org/10.52842/conf.ecaade.2014.1.145
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 145-152
summary	This research develops a method for the analysis, integration and visualisation of climatic parameters in a dense urban block. In order to test this method, a typical urban block in Manila, Philippines, is investigated and results are represented through computational simulation. The translation of latent spatial qualities into visual data with common tools and techniques allows designers to gain an understanding of how to design local microclimates, and inhabitants to gain greater knowledge of the environment. In this regard, this research proposes, contrary to conventional methodologies, the use of analytical tools as the impetus to, rather than the outcome of, architectural design.

title	On the Shores of Architecture

summary	This paper explores the implications of complex geometry enabled by computational technology to architectural theory and practice. It reviews the different design paradigms engaged breaking the horizontality of the floor and ceiling or fusing them together. It argues that current advances in fluid dynamics simulations open a new frontier in the conception of the usable architectural surface, in which the architectural product is no longer a fixed object, but the interaction between a fluid, changing environment and built form. The paper presents a case study in which computational fluid dynamics are utilized to reconvert a disused breakwater into a ‘blue garden’. The morphology of the breakwater and its texture are calculated to produce the conditions amiable for supporting a varied marine ecosystem, and to shape the waves to generate aesthetically meaningful sensations. The essay discusses the technical and conceptual challenges of controlling the nonlinear behaviour of fluids. It then speculates on the theoretical ramifications of having the surface interact with exterior forces and the subject's imagination to produce an event enfolding in time.

title	A CFD Analysis of the Urban Morphology Effect on Air Pollutants Dispersion
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 395-403
summary	Air pollution in urban environments can have negative consequences on people's health and comfort of city-dwellers, and on the durability of buildings. Understanding the transfer and deposition of pollutants in the urban environment is therefore essential in the design process of a building. Computational simulations can aid in understanding the pollutant/chemical dispersion in the urban cityscapes. Computational fluid dynamics (CFD) represents the study of fluid mechanics with the use of computer models and simulations. In this paper we study the impact of urban planning on pollution dispersion, the dispersion characteristics, such as the spread of the pollution dispersions, have been determined for different wind speeds and wind directions.

summary	The study of wind conditions in the urban context has multiple application areas such as for cleaning pollution through ventilation, analysing wind pressures on building façades, and improving pedestrian comfort. In this context, the Pneumosense project is a student’s project focused in the design of a kinetic system to ameliorate negative impact of wind conditions in pedestrian areas in the city of Melbourne. Its development considers several stages including site analysis, analogue wind tunnel testing, digital simulations with Computational Fluid Dynamic software, material explorations, kinetic component design with Arduino, and rapid prototyping.

summary	The manufacture of concrete funicular shells often relies on traditional formwork construction techniques to provide a sculptured cavity for the fluid material to occupy (Bechthold, 2004). While this enables a predictable geometric outcome, the extensive use of timber and/or steel to construct these formworks account for up to 60% of the total production cost of concrete and are discarded after the casting is complete (Lloret et al. 2014). Thus, we propose an alternative method to create prefabricated modular systems out of concrete casted in customised tubular knitted membranes. These perform as a network of struts that can be affixed onto 3D printed nodes of a singular design. Altogether, these components serve as a kit-of-parts that can be transported to site and assembled together to create shell geometries.

title	Aerodynamic strategy applied in an urban shelter design - Simulation and analysis of aerodynamic phenomena in an urban context
doi	https://doi.org/10.52842/conf.ecaade.2014.1.137
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 137-144
summary	This paper presents an experimental study on strategies of utilizing wind as an architectural element, proposing the reconfiguration and projection of wind patterns to produce vaults of wind as regions of shelter in the outdoor environment. It shows an aerodynamic analysis and exploration of barriers, deflectors and porous screens in an existing urban wind canyon for a hypothetical urban shelter in a tram stop area. Computational Fluid Dynamics (CFD) software and physical tests in a wind tunnel using microelectronic hot-wire anemometry are the methods utilised. The experiments involve a comparison between screens with impermeable surfaces and porous membranes and their ability to project wind as architecture. The experiments showed that the use of porous membranes improves the mitigation level of wind speed and turbulence intensity in the wind vaults regions.

title	Crafting and Assessing Urban Environments Using Computational Fluid Dynamics
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 315-322
summary	Computational Fluid Dynamics (CFD) is a reliable tool for the analysis of outdoor and indoor climatic related conditions. Due to rapid population growth the need for dense urban developments and high-rise buildings became demanding. This led to creating the phenomenon of urban heat islands and deteriorating air quality and thermal discomfort. This research highlights the potential of adopting CFD as a simulation technique to investigate the complex fluid flows in urban thermal environment. It discusses the advantages and limitations of CFD tool. It describes the CFD simulation approach and the procedure for conducting CFD simulation. This paper also gives some examples of case studies of CFD assessment for indoor and outdoor urban environments.

title	Approximating Computational Fluid Dynamics for Generative Tall Building Design
source	International Journal of Architectural Computing vol. 12 - no. 2, 155-178
summary	Background literature review, methodology, results, and analysis are presented for a novel approach to approximating wind pressure on tall buildings for the application of generative design exploration and optimisation.The predictions are approximations of time-averaged computational fluid dynamics (CFD) data with the aim of maintaining simulation accuracy but with improved speed.This is achieved through the use of a back-propagation artificial neural network (ANN) with vertex-based shape features as input and pressure as output.The training set consists of 600 procedurally generated tall building models, and the test set of 10 real building models; for all models in both sets, a feature vector is calculated for every vertex. Over the test set, mean absolute errors against the basis CFD are 1.99–4.44% (_:2.10–5.09%) with an on-line process time of 14.72–809.98s (0.028s/sample). Studies are also included on feature sensitivity, training set size, and comparison of CFD against prediction times. Results indicate that prediction time is only dependent on the number of test model vertices, and is therefore invariant to basis CFD time.

summary	Scattered solid is a conceptual model consists of a pair of force sources - attractor and repulsor - and particles that possibly bonds together. We hypothesized an abstract or imaginary force field causing particles to move that we can control the tendency of organization by modifying the force fields with a set of parameters such as intensity by distance, time and geometry.
