title Aerodynamic Performance Driven Form-Generation for Skyscraper Design
source Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 315-326.
summary I have conducted a study to explore aerodynamic performance as a driver for skyscraper design, utilizing up-to-date parametric design and computational fluid dynamics (CFD) technologies readily available to architects. Previous scientific research has suggested strategies in modifying the form of skyscrapers for the purpose of improving their aerodynamic performance. I have incorporated six of such strategies into parametric design tool to produce a matrix of 60 prototypes. These prototypes are subjected to qualitative and quantitatively evaluation iterations to yield the most optimized design, with considerations given primarily to aerodynamic performance, and secondarily to structural robustness, program potential, and image attractiveness. The selected design option is further developed into a skyscraper concept. A multi-staged aerodynamic performance-driven design process is the most important result of the study. In addition, two valuable insights have been obtained: first, to inject a new inspiration into the design of skyscrapers, I have implemented the MultiDisciplinary Optimization (MDO) methodology from the aerospace industry. Second, I am able to support form-generation parametric design by quantitative evaluation process.
