| Summary: | 博士 === 國立臺北科技大學 === 設計學院設計博士班 === 103 === Eco-Architecture is a concept of environment and energy sustainability in order to solve the insufficient of global resources, but lacking of effective evaluation method is serious weakness of Eco-Design. How to apply scientific methods and assessment techniques to improve the Eco-Architecture design is major concern to modern designers. At present time, practical simulation tools following with the digital and information technologies development, Performance-oriented Architecture Design is an approach which use of simulation technology to modify design project or built environment. Computational Fluid Dynamics (CFD) technical has becomes an important simulation tool which integrates with the process of architectural design. Many invisible physical factors of environment (such as wind etc.) could be visualized and counted by CFD analysis. The results can use as the basis for the design improvement. As a relative scientific design support method, it runs as a critical role for the development of Eco-Architecture design and the new generation of urban patterns to achieve the concept of sustainable development in future. In this study, researcher studies several cases of famous architectures in the world through CFD turbulence model, and summarized following conclusions:
1.The CFD-based predictions of Tjibaou Culture Center illustrates that the improved design for strengthening the effectiveness of natural ventilation at the normal wind level indicates a significant growth in the volumetric flow rate from 19.24 to 39.34m3/s via an increase of the aeration area in conjunction with minimized obstacles along the flow pathway.
2.The unique form of Guggenheim Museum also causes strong turbulences on the leeward side. The Guggenheim Museum is designed with an irregular fluidic way along the river bank; leading to the positive and negative influences on the physical urban environments reveals by the CFD simulations.
3.We can recognize in depth about the building performance of unique architectural design through the computational simulation analysis. The wind crossing through the building becomes unpredictable due to the round shape of Eryi Lou, particular positions at both ends, the wind velocity to the leeward of Eryi Lou can reach 2.8 m/s.
4.Traditional architectural design has remarkable ingenuity; they could be as great example of reference for ecological architectural design. Performance-Oriented Design concept and CFD simulation will become important tools for architects and designers in the future.
