title	Teaching and Learning Building Performance Virtualisation

summary	Building performance simulation tools have indeed eased the task of evaluating a building’s performance from the point of view of lighting design, heating and cooling loads, total energy loads, acoustic properties, natural lighting, ventilation, smoke and fire containment etc. However, to use these tools correctly, not only is theoretical knowledge required but also insight that can only be attained after substantial experience. For example, in order to evaluate the thermal performance alone, one needs to understand climatology, material properties, building physics, HVAC systems, internal and external gain factors, solar impacts, etc. to name a few. Hence, teaching students of Architecture how to use these tools, and also to interpret the results properly, is a tall order. This paper reports on insights gained through teaching courses on building performance simulations to graduate students in the Department of Architecture. The course content was varied each term and a different simulation software was used; namely: ECOTECT, Energy Plus and Design Builder. Data presented here will also contain feedback from the course students regarding the modelling process of the buildings, inputting the data, simulating their performance, and evaluating the results. Also, the difficulties faced during the various steps as well as the drawbacks of the tools will be discussed in depth.

title	Space Planning and Preliminary Design Using Artificial Life
doi	https://doi.org/10.52842/conf.caadria.2014.657
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 657–666
summary	The majority of CAD tools are designed for precision modelling of forms. The very earliest stages of design tend to be worked through with traditional media such as sketching with pen or pencil. A reason why this is, stems from the difficulty of drawing or diagramming uncertainty or vague ideas in a traditional CAD application. When a designer is still working through the design, pen and pencil are a means of exploring. While any simple pencil sketch can be imitated using CAD, this is too time consuming and limiting when compared with traditional media. This paper presents research in a prototype for a early stage planning software application using blobs (closed recursively subdivided curves) and ideas from artificial life. While not a replacement for sketching, the aim of this research is to provide a means of diagramming preliminary ideas as exploring the idea of a dialogue between humans and computers. The shapes represented in the software use physics simulations and act as 'soft-bodies' allowing users to manipulate them in various ways. Ideas from artificial life simulations are used to have the shapes interact with each other and produce unexpected configurations. The aim of these interactions is to trigger a response from the user and to allow them to explore configurations that they did not anticipate.

title	Progeny: A Grasshopper Plug-in that Augments Cellular Automata Algorithms for 3D Form Explorations

summary	Cellular automata (CA) is a well-known computation method introduced by John von Neumann and Stanislaw Ulam in the 1940s. Since then, it has been studied in various fields such as computer science, biology, physics, chemistry, and art. The Classic CA algorithm is a calculation of a grid of cells' binary states based on neighboring cells and a set of rules. With the variation of these parameters, the CA algorithm has evolved into alternative versions such as 3D CA, Multiple neighborhood CA, Multiple rules CA, and Stochastic CA (Url-1). As a rule-based generative algorithm, CA has been used as a bottom-up design approach in the architectural design process in the search for form (Frazer,1995; Dinçer et al., 2014), in simulating the displacement of individuals in space, and in revealing complex relations at the urban scale (Güzelci, 2013). There are implementations of CA tools in 3D design software for designers as additional scripts or plug-ins. However, these often have limited ability to create customized CA algorithms by the designer. This study aims to create a customizable framework for 3D CA algorithms to be used in 3D form explorations by designers. Grasshopper3D, which is a visual scripting environment in Rhinoceros 3D, is used to implement the framework. The main difference between this work and the current Grasshopper3D plug-ins for CA simulation is the customizability and the real-time control of the framework. The parameters that allow the CA algorithm to be customized are; the initial state of the 3D grid, neighborhood conditions, cell states and rules. CA algorithms are created for each customizable parameter using the framework. Those algorithms are evaluated based on the ability to generate form. A voxel-based approach is used to generate geometry from the points created by the 3D cellular automata. In future, forms generated using this framework can be used as a form generating tool for digital environments.

title	Efficiency in Architectural Geometry Informed by Materials
doi	https://doi.org/10.52842/conf.ecaade.2014.1.547
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. 547-554
summary	Although some studies investigate physics-based dynamic systems to generate structurally efficient forms by incorporating geometry with performance requirements, there is a gap in the field questioning on how to link structurally efficient architectural geometry with mechanical properties of materials. The aim of this paper is to question the possibility of generating an information loop in which Young's Modulus, stiffness of the material may both inform the form-finding process and the structural performance simulation. The proposed method offers steps including form-finding, series of analyses applied for architectural geometry and structural performance, as well as optimization. Based on the simulation results, efficiency values are calculated driven by the use of different materials. The significance of incorporating material properties in the early design stage is underlined, by comparing differences, whether the stiffness of material informs the form-finding process or not.

summary	This paper outlines a developing teaching and research pedagogy being developed at an educational institution in the United Arab Emirates that resists contemporary models of Computational Orientalism. The paper describes that exploring the space between Middle-Eastern material culture and contemporary computational design methodologies as generative, systemic, and adaptive conditions allows for the development of a material culture that is both local and driven by the computational zeitgeist. More specifically, the paper outlines the historical relevance of the computational spline and how it is being explored to develop a novel material culture through parametric models and physics-based systems.
