title Computational Fluid Dynamics for Architectural Design

summary Computational Fluid Dynamics (CFD) is a cost-effective, well-known technique widely employed in industrial design. While indoor analysis can be achieved via CFD, Wind Tunnel Testing (WTT) is still the prevailing mode of analysis for outdoor studies. WTT is often only performed a few times during the course of a building design/construction cycle and primarily for verification purposes. This paper presents a cross-disciplinary research initiative aiming to make CFD understandable and accessible to the architecture community. Our particular interest is in the incorporation of CFD into the early stages of architectural design. Many critical decisions, including those pertaining to building performance, are made during these stages, and we believe access to wind/airflow information during these stages will help architects make responsible design decisions. As a first step, we designed a passive cooling canopy for a bus stop based on the equatorial climatic conditions of Singapore where wind/airflow was a driving factor for geometry generation. We discuss our strategies for overcoming the two bottlenecks we identified when utilising CFD for this framework: mesh generation and result comprehension/visualisation.

title Judgment and Decision-Making Aspects on the Use of Virtual Reality in Volume Studies

summary The most common reason for using Virtual Reality (VR) as a communication medium in urban planning and building design is to provide decision makers with access to a shared virtual space, which can facilitate communication and collaboration in order to make better decisions. However, there is a risk that judgmental biases arise within the virtual space. The displaying of the VR-models and itscontent could be one way of changing the settings for the visual access to the virtual space and could thus influence the outcome of the decision making process. For that reason it is important to have knowledge of how different settings in and around the VR-medium influence the experience of the shared visual space that the VR-medium strives to achieve. In this case the decision-making process, perceptions of space, and the cognition process of decoding of information in the visual space are important. This paper investigates how reference points influence judgments of a volume study of a building and furthermore what visual cues that are used for spatial reasoning about volumes. The results show that the initial visual information has a profound impact on the decision, even when this information lacks in validity.

summary This paper analyses two ideation principles: idea accessibility and idea connectivity. Access refers to the likelihood to generate a particular idea or set of ideas for a given design task. Connectivity refers to the likelihood of one idea leading to other ideas. These principles are evaluated through a computational model. The results suggest new metrics to assess the value of new ideas. Evaluating new ideas by their accessibility and connectivity has the potential to transform current idea generation practice and research.

summary This paper sets out to document the procedural design and implementation of “Siphonophore” a multisensory digital ecology, mimicking colonial-ordered behaviour systems. The exploration of the notion of “self” in a complex system of highly integrated individuals with reference to the emergence of behaviours from the human-machine-context interaction, is engaged by this open system’s hierarchical articulation of electronics, Arduino boards, sensors and programming routines. User interaction and recorded statistics from the system’s core algorithm are assessed, in relation to the capacity of this prototype to provide an alternative methodology of describing collective intelligence, while presenting a non-standard perspective of body-space interaction and design as entertaining art. The overall impact is discussed in relation to the examined observations, towards a potential advancement to a system of superior contextual understanding.

summary This paper outlines some investigations from a project which utilizes computing and scripting of specific site components, spatio-temporal movement and behavioural patterns to explore how designer might understand people activities and formulate design interventions within public spaces. This research looks at how generative tools can facilitate designers to integrate the large volume of information received by hybrid data collection, and conventional data analysis directly into the design process. Through an examination of sensing urban space, this research proposes a method to track and record people’s movement patterns in order to implement them via generative design tool. To facilitate this, a scripting method is specified; which uses sensors and motion tracking devices to capture the use of a specific public space. This project proposes a methodology for developing designed spaces and optimal pathways generated from real-time data and feedback captured by sensors.

summary Architecture has always been founded upon ideologies. However could the influence of human interactions create a new perspective for space form evolution? To create a spatial adaptive system, to the influence of culture and behaviour of human being? The output of this spatial system is the determination of optimised values for spatial configurations by biomolecular, self-assembly computation for emergent spatial forms.

summary In this paper we explore the concept and design guidelines for an Autonomous Learning Oriented Proto System (ALOPS), a construction system designed to enhance its own performance through time. Our research has been focused on the fabrication of a prototype for a porous wall system which reacts to light intensities by closing or opening its apertures. Taking that aim, we used a combination of robotics, programing, and material behaviour to endow the system with the capacity to record reactions towards encountered sets of conditions during its active energy periods, allowing the system to use this knowledge database to evolve autonomously by feeding this information back into the computation process. This approach in construction systems opens up the architectural design processes to address the creation of digital memory structures rather than complex algorithms in order to operate specific functions. With this development, the architect could think of architectures constantly evolving by learning from their environments as well as of users forming symbiotic and behavioural bonds with the emergent spatial personalities, thus affecting the underpinning relationships between architecture, user and context.

summary This paper proposes an architectural system interactive to both users and the environmental condition in real-time. While nature acts as a global control for the system, the user can alter it locally. Due to the increasing digitization of our contemporary culture, there is an unprecedented capacity for information to flow in our physical and socially net-worked world that can be used to inform design problems and processes. Live and real-time information sources, like Twitter, could be virtually scanned for specific data input associated to a par-ticular geometrical manipulation. This process enables a collective group of users to inform the system. As the number of users increases there is collaboration for defining the form which is different from single user interaction. Since the model is associated with a specific definition of generative behaviours as described by the words, these definitions could be used as the

summary This work is a research on the application of genetic algorithms (GA) to urban growth taking into account the optimization of solar envelope and sunlight in open spaces.It was considered a typical block of a Spanish grid, which is the most common subdivision of the urban land in towns situated in Argentina. Two models are compared, one in which the growth has no more limitations than building codes. The other one, in which the growth incorporates the solar radiation as a desirable parameter.This way of parameterizing configures a bottom-up method of urban growth. No top-down decisions intervenes in the growth process.This tool proves to be useful at early stages of urban planning when decisions—which will influence along the development of the city for a long time—are taken.

summary In urban planning exploration and analysis assist the generation, measurement, interpretation and management of the modelled urban environments. This frequently involves categorisation of model elements and identification of element types. Such designation of elements can be achieved through attribution (e.g. ‘tagging’ or ‘layering’) or direct selection by model users. However, for large, complex models the number and arrangement of elements makes these approaches impractical in terms of time/effort and accuracy. This is particularly true of models which include substantial numbers of elements representing existing urban fabric, rather than only newly generated elements (which might be automatically attributed during the generation process). We present methods for identification and categorisation of model elements in models of existing and proposed urban agglomerations. We also suggest how these methods can enable exploration of models, discovery of identities and relationships not otherwise obvious, and acquisition of insights to the models’ structure and contents which are not captured, and may even be obscured, by manual selection or automated pre-attribution.

title Exploration of Urban Street Patterns – Multi-Criteria Evolutionary Optimisation Using Axial Line Analysis

summary In urban design, researchers have developed techniques to automate both the generation and evaluation of urban street patterns. In most cases, these approaches are investigated in isolation from one another. Recently, a number of researchers have attempted to couple these approaches, in order to enable larger numbers of street patterns to be generated and evaluated in an iterative loop. However, to date, the possibility of fully automating the generative-evaluative loop using optimisation algorithms has not been explored. This research proposes an explorative design method in which urban street patterns can be optimised for multiple conflicting performance criteria. The optimisation process uses evolutionary algorithms to evolve populations of design variants by iteratively applying three key procedures: development, evaluation, and feedback. For development, a generative technique is proposed for constructing street patterns. For evaluation, various performance measures are used, including in particular Space Syntax based Axial Line analysis. For feedback, a Pareto-ranking algorithm is used that ranks street patterns according to multiple criteria. The proposed method is demonstrated using an abstract scenario in which orthogonal street patterns are evolved for a small urban area.

summary This paper proposes a design method for the exploration of holistic low exergy design strategies which factor in limitations and constraints of both passive and active systems. A design method that consists of a two loop structure is proposed. The inner loop consists of an automated workflow that includes three main components: a developmental procedure for generating design variants; evaluation procedures for evaluating design variants; and an optimisation procedure for optimising populations of design variants. The outer loop consists of a manual workflow that has two main components: a schema formulation process for defining the inputs to the automated workflow and a data analysis process for analysing the data produced by the automated workflow. A case study is presented that demonstrates the proposed method.

summary Natural surveillance is one key factor proposed, in the approach to decrease fear of crime. Building fenestrations and outdoor spaces like terrace, balconies and verandas that extend the interior spaces and the indoor activities, beyond the closed external shell of the buildings, are proposed by CPTED, in their place specific policy guidelines, to help design out fear and crime. In this background, this study on natural surveillance opportunities, explores typological variations of these component outdoor spaces of buildings, in line with variations in size and location. The affordances considered for this study specifically focus on the ways in which these spaces structure the visual fields for the external observer. This paper thus reports the survey of visual preferences exploring the spatial affordances of building spaces and their association with fear of crime.

summary In this paper, the authors consider the problem of architectural spatial performance indicators for assessing computer generated design, where identification and analysis of meaningful and relevant spatial qualities is the target of assessment. The paper presents a parametric spatial analysis schema and spatial database structure for the restricted, but still significant, domain of residential housing. A process for the capture and comparison of different types of architectural spatial data is described where analysis focuses on a series of 2D metric and topological spatial measures. The process is then demonstrated in our discussion of a descriptive scenario.

It shows the accuracy of such grammar to help tracing the degree of influence of Alberti’s treatise in Renaissence Portuguese architecture. Rucellai palace facade ornaments and its interior loggia where used to analyze and compare the Loggia generation accuracy. A Grasshopper script is used for the automation of the rules derivation. An evaluation process is presented and its use aims to better understand the deviations between the treatise and the Loggia grammars.
