Toward the wind-related building performative design: A wind-related building performance optimization design system integrating Fluent and Rhinoceros based on iSIGHT

The integration of optimization algorithms and building performance simulation tools make it possible to carry out performative design or performance-driven design, which aims to guide the design synthesis process of the simulation results to continuously improve the design. However, the associated research work of windrelated building performance is still deficient, resulting from lack of applicable interface and the time consumption. Meanwhile, in the industrial design realm, the aero-dynamics or fluid-dynamics behaviour of the production under development has been vastly analysed and optimized based on the multi-discipline optimization (MDO) techniques. Owing to offering numerous built-in interface and integrated optimization algorithm, MDO application software has begun to be used in building optimization design with the complex relationship between various objectives. With the advantage of MDO tools and aimed to provide an efficient optimization approach from the perspective of architect, this paper proposes a wind-related building performance optimization design system integrating Rhinoceros and Fluent based on iSIGHT - A MDO application software. In addition, the lighting performance is considered in this research as well for implementing the multi-objective optimization. Two case studies of tall building optimization design based on varied generative approaches are introduced to investigate the effect and efficiency of this system.
