本文旨在探讨影响建筑能源性能和可再生能源技术实施的城市微气候特征。在伦敦一个人口密集的城市地区，设计了一项实验活动来研究小气候参数，包括空气和地表温度、水平和垂直表面的直接和漫射太阳辐射水平、风速和风向。研究结果表明，气候参数受到城市肌理属性的显著影响，这突出了在建筑设计阶段提供和使用微气候信息的必要性。这项研究为伦敦人口密集的城市地区提供了一套有价值的小气候信息。根据研究结果，可再生能源技术实施的可行性研究和建筑热/能源性能评估需要使用微气候信息，而不是主要从非城市环境收集的气象天气数据。
This paper aims to address the characteristics of urban microclimates that affect the building energy performance and implementation of the renewable energy technologies. An experimental campaign was designed to investigate the microclimate parameters including air and surface temperature, direct and diffuse solar irradiation levels on both horizontal and vertical surfaces, wind speed and direction in a dense urban area in London. The outcomes of this research reveal that the climatic parameters are significantly influenced by the attributes of urban textures, which highlight the need for both providing the microclimatic information and using them in buildings design stages. This research provides a valuable set of microclimatic information for a dense urban area in London. According to the outcomes of this research, the feasibility study for implementation of renewable energy technologies and the thermal/energy performance assessment of buildings need to be conducted using the microclimatic information rather than the meteorological weather data mostly collected from non-urban environments.
