Studio Abstract The Coding Density studio focuses on developing emergent skills in computational design, real-time data analysis, data visualization and relational modelling of heterogeneous parameters which shape our cities. The studio, shall apply these skills to dissect and propose fully scalable generative design systems which will primarily aid in critically questioning “Density”. Questions such as: What multi-programmatic spatial entities constitute this density, How much density (good or bad), What implications does it have on critical issues of Mobility, Health, Economics, Energy and how does this help in the actual Informed Planning of a city, shall thus become critical to the studio. The Aerotropolis City: the New West, shall be taken as a case for the studio. Through the prism of computational design and new media, we, will thus together address the following questions: What urban growth would the proposed Western Sydney Airport’s becoming a new gateway to the city imply? How should we strategically use the influence of the airport and the Sydney Metropolis to catalyse an Aerotropolis development with a viable/performative density of business, recreation and living? Studio Keywords Urban Regeneration, Predictive Modelling, Density, Typology, Systems thinking, Computational Design, Generative Systems, Relational Modelling, Data Visualization Detailed Studio Description Three predominant factors, namely digital ubiquity in the contemporary urban environment, increasing rate of urbanisation and a shift from an Industrial economy to an economy driven by digital information and service provision, contribute to a paradigm shift in the domain of urbanism. In order to understand the city within this context as a complex dynamic system an upgrade in the palette of analyses, modelling, visualization and generation tools is quintessential. The Coding Density studio thus focuses on developing a mediated design thinking outlook within young designers which will focus on the creative use of computational design techniques for developing cutting edge generative design tools. The studio shall explore how to systematically understand and visualize the city as an emergent outcome of a multitude of parameters (environmental, economic, social, spatial, political). The goal of the studio is thus to develop prototypes for participatory and replicable frameworks that allow citizens and urban decision makers to assess key performance indicators in a holistic manner. The Coding Density studio, shall operate as a Research by Design studio with its aforementioned agenda and shall conduct generative design experiments for outlining design strategies for the Aerotropolis development of the new Western Sydney Airport. Differences between an Aerotropolis and conventional Metropolitan city and the embedded value propositions it proposes in terms of smart infrastructure shall be studied using global examples of Aerotropolis cities. The multi-level impact, which this mega infrastructure shall have on the growth of Western Sydney and the vital connection it has to maintain/establish with the Sydney Metropolis, shall both be investigated in the studio. These impacts will range from economic impacts, changing demographic and influx of migrants, job creation, proportional zones of development/growth in various parts of Western Sydney, impact on natural resources, impact on infrastructure. The case studies of other Aerotropolis’s shall act as a vital database for understanding the mistakes and benefits of such developments globally. The studio shall gradually zoom in from an overall analysis of the East, Central and West Sydney to the Aerotropolis zone, the identification of various growth clusters within the Aerotropolis and subsequently dive into each cluster/urban block. Each iterative step and scale change is informed by the one before, while attaching vital urban factors such as Energy, Mobility and Environmental studies to them and shall lead to the extraction of parametric rulesets and their relational influences on each other and shall populate a generative design system. ‘Density’ being the operative term, shall become the driver for statistically and relationally modelling predictive urban growth models for Western Sydney. The generative design and predictive modelling phase shall begin with an intensive one week workshop outlining the computational nuances behind designing such systems and will train the students to acquire a systems perspective envisioning the Aerotropolis. This vision and the proposed role of the computational strategies will constitute the Mid-Term review. Post mid-term, each group shall engage in a collaborative design workflow wherein three criteria for the Aerotropolis become central: Productivity, Liveability ad Sustainability. A further narrowing down of associated growth clusters, associated densities and environmental impacts shall be bound in a feedback loop which will influence each group’s decision via connected computational databases. From this phase onwards the groups shall further develop their cluster/urban block via a generative design system and shall dive into data visualization and simultaneous impact assessment scenarios of each iterative generation. 3d printing successive generations of growth densities with associative parameters shall further help in understanding various density models at each group’s cluster level. From this associated cluster collective, the studio shall further dive into merging each group’s computational systems into one big digital platform to visualize the entire Aerotropolis generation while at the same time diagramming strategies for embedded sensing systems for monitoring energy, mobility and environmental parameters. Individual students can then dive into this generative system to tweak parameters and further generate their own visions for experimental densities, which they shall defend. The Coding Density studio shall thus look at the Aerotropolis as a case for developing an associative systems attitude towards understanding the city. Understanding how urban data can be parametrically linked, analysed and visualized, will thus form the
backbone of the studio. The smart sensing and data collection diagramming phase shall mark the second phase of the studio in March, which will be conducted as an International Design studio in collaboration with the TU Delft, Netherlands. Students are thus encouraged to enrol for the follow up, wherein we shall dive deeper into collecting real-time data via embedded sensing systems within the urban and develop real-time interactive installations which thrive on the collected data for the March semester.

Studio specific description At this phase, the 2D and 3D computational experiments should illustrate the interrelation between the different functions and parameters, and their impact on the schematic urban formations. Each group will explore the performance of their selected salient feature as a key factor that regulates urban resilience, indicating in a parametric manner how local variations can affect the three set criteria (Productivity, Liveability and Sustainability) in the context of their selected urban block.
