能源系统是城市生态系统的重要组成部分,近年来由于环境压力和产业转型需求,引发社会普遍关注。文章从城市设计视角对密度和类型概念进行剖析,在传统和现代城市形态间开展比较研究,建立城市形态因子同能源性能的相关性,进而通过上海街区能源性能模拟试验,探索了多目标决策下密度和类型的设计方法。最后,提出高能效城市设计的理念并对其应用展开进一步讨论。
Energy system is an important part of urban ecosystem. In recent years, due to environmental pressure and industrial restructuring demand, it has aroused widespread public concern. The article analyzes the concept of density and type from the perspective of urban design, and makes a comparative study between the traditional and modern urban morphology to establish the correlation between urban form factor and energy performance. Through the energy performance simulation test in Shanghai block, the article explores the multi-objective decision-making Density and type of design method. Finally, the concept of energy-efficient urban design is put forward and its application is discussed further.
