摘要

本文提出了一种应用计算流体力学(CFD)和EcoTect工具对可持续城市设计项目进行定量研究的方法。本文是一项资助研究的一部分,于2010年完成。本研究是东北曹飞店生态城市规划与开发的一部分;是中国首批生态城市试点中首批生态城市建设项目之一。研究方案涉及生态设计和可持续性方面的良好做法的主要方面。这些方面包括建筑物周围的风流分析、开放空间的日照分析、水系统中的污染物扩散和城市公路的噪声控制。本研究旨在探索一系列的研究方法,以提高综合规划阶段的综合设计绩效。强调跨专业和学科边界的评估整合,以确定可持续性和设计之间的关键差距。本研究的主要方法是将CFD和EcoTect工具应用于更大的城市区域的环境绩效,而不是通常用于建筑干预或项目的直接户外空间。本研究提出了一个综合的城市设计模型,并应用了计算工具(例如CFD和EcoTect),以及这些工具如何从技术层面提供更全面的方法来执行设计和规划的最佳实践。最后,提出了实现城市可持续发展的综合城市设计模式。

Application of environmental performance analysis for urban design with Computational Fluid Dynamics (CFD) and EcoTect tools: The case of Cao Fei Dian eco-city, China

This paper suggests a type of quantitative research method with the application of Computational Fluid Dynamics (CFD) and EcoTect tools for a sustainable urban design project. This paper is part of a funded research study and was completed in 2010. This study is part of the larger project for planning and development of Cao Fei Dian eco-city development in North-Eastern China; one of the first eco-city development projects in the first batch of pilot eco-cities in China. The research programme addresses the main aspects of good practice in terms of eco-design and sustainability. These aspects include wind flow analysis around buildings, insolation analysis of open spaces, pollutant dispersion in water systems and noise control on urban highways. This study aims to explore a range of research methods in order to enhance the performance of integrated design with a comprehensive planning stage. The integration in evaluation across professions and subject boundaries is emphasised to identify the key gaps between sustainability and design. The main method of this study is the application of CFD and EcoTect tools for environmental performance of a larger urban area than the common use for architectural interventions or immediate outdoor spaces of a project. This study suggests an integrated urban design model with the application of computational tools (i.e. CFD and EcoTect in here) and how these could inform, from a technical dimension, a more comprehensive approach to executing best practice in design and planning. The paper concludes by suggesting an integrated model of urban design to achieve urban sustainability.
