题目 基于微气候分析的城市中心商业区空间形态研究——以南京为例
主题词 微气候,室外热舒适度,建筑能耗,中心商业区,空间形态
摘要 近年来,随着城市热岛效应的加剧,人们逐渐开始关注街区尺度的物质空间形态与微气候环境之间的关联机制。城市中心商业区作为城市中建筑、交通及人类活动最密集的核心区域,其物质空间形态具有高密度、高高度、高强度的典型特征,且对城市微气候产生直接影响。然而,目前关于城市中心商业区建成环境与微气候之间关系的量化研究相对较少,同时也缺少与气候适应性原则相关的城市设计标准与设计导则。因此,本研究基于南京的典型夏季气候条件,针对城市中心商业区的物质空间形态要素,探索分析其对外部微气候环境及与微气候相关的室外热舒适度和建筑能耗的影响,并基于分析结果,提出具有气候适应性的中心商业区空间形态设计导则与优化策略。 本文首先基于不同时期的地表温度与气温实测数据,分别对南京市地表热岛效应与大气热岛效应的时空分布特征进行研究,并分析南京市城市热岛效应形成的深层原因及变化规律。根据分析结果,在热岛强度最高的区域选取若干代表性街区,分析并讨论了其空间形态参数与微气候要素之间的关联。 然后,提出分别从街道层峡形态、街区肌理形态、街区建筑形态及排列布局方式三个层面对街区物质空间形态的相关参数与控制因素进行解析与分类量化的研究方法,并利用数值模拟技术评估分析街道高宽比、朝向、天空视角系数、容积率、建筑密度、平均建筑高度、建筑数量与布局、建筑形态、建筑排列与布局等多种物质空间形态参数与控制指标对微气候要素及与微气候相关的室外热舒适度和建筑能耗的影响机制。该研究方法有利于从气候适应性的角度对不同的城市设计方案进行对比优选。 同时,本研究通过对比局地天气数据与气象站记录天气数据对街区建筑能耗结果的影响,提出在建筑能耗模拟预测研究中,采用考虑了目标建筑周围环境影响的局地微气候数据,可使能耗预测结果更具针对性、准确性及实用意义。 最后,基于分析结论,结合部分已有成果,以热舒适性与低能耗为目标,总结归纳了在城市设计实践中分别针对街道高宽比、街道朝向、街道形态、街区建筑密度、平均建筑高度、建筑容积率、建筑数量与布局、建筑形态、建筑排列与布局方式等9个方面进行气候适应性设计的相关具体优化策略与措施,并在相关案例中进行了应用分析。
英文题目 Research on Urban Spatial Form of CBD Based on Microclimate Analysis——A Case Study of Nanjing
英文主题词 Microclimate; Outdoor thermal comfort; Building energy consumption; Central Business District; Spatial form
英文摘要 Due to the aggravating of urban heat island (UHI) phenomenon, the correlation between urban physical spatial form at street level and microclimate has drawn the attention of researchers gradually over recent years. As the densest core area with buildings, traffics and human activities in the city, the urban physical space of Central Business District (CBD) is characterized by high coverage, height and development intensity, and exerts direct effects on urban microclimate. Nevertheless, the quantitative studies on the relationship between the built environment of CBD and microclimate are relatively less for now, and so is the urban design criteria and guidelines for the climate adaptability. Therefore, this work aims to explore the impacts of the urban physical spatial form of CBD on the outdoor microclimate and related thermal comfort and building energy consumption under the typical summer conditions of Nanjing city, and propose the design guidelines and optimization strategies of urban space form for climate adaptability in CBD area. Firstly, this thesis has investigated the spatial and temporal characteristics of surface and canopy layer heat island distribution in Nanjing city by using the data of land surface temperature and measured air temperature, and analyzed the reason and variation regularities of the UHI in Nanjing. Based on the results, some street blocks in the area with highest UHI intensity are selected as the typical cases, and the correlation between the urban geometries and microclimate has been examined and discussed. Then, this study has proposed the research methodology of classifying, analyzing and quantifying the parameters and controllable variables related to the urban physical spatial form at three level, including street canyon geometries, urban texture, and building form and arrangements. Furthermore, the numerical simulation is employed to evaluate and analyze the effects of multiple parameters and controllable variables of urban physical spatial form on the microclimate and related outdoor thermal comfort and building energy consumption. The proposed method is propitious to the comparison and preferable selection among various urban design schemes for climate adaptability. In the meantime, this research has shown the difference between the impacts of the localized weather data and the recorded one on building energy simulation results, and highlighted the importance of the implementing the localized weather data in building energy simulations and predictions which can make the simulation results more pertinent, accurate and practical. Finally, based on the conclusions and some achievements, the specific optimization strategies and solutions for climate adaptive design on 9 aspects, including street aspect ratio, orientation, street geometry, building site coverage, building height, floor area ratio, plot layout, building form and arrangements etc., have been summarized and induced with the aim of thermal comfort and low energy consumption. Also, some case studies have been conducted by applying these optimization strategies.
