The application of a high-density street-level air temperature observation network (HiSAN): 3D-built information on thermal environment and the prediction of urban thermal comfort

Abstract

In the past the research on the relationship between urban development and thermal environment was mostly based on planar ring domain analysis this study tried to operate in the way of three-dimensional (3D) space factor In order to understand the microclimate we use the High Density Street-level Air-temperature observations Network (HiSAN) of Tainan Metropolitan Area which is composed of 100 measuring points to discuss First the fisheye diagram is used to quantify the characteristics of the 180-degree and further explore the relationship between the three-dimensional material composition and the thermal environment According to the influence of the degree of sky view factor (SKV) in three-dimensional space on thermal comfort the Physiological Equivalent Temperature (PET) of Rayman is analyzed with correlation to establish a simplified formula of thermal comfort index and to overcome the problem of complicated calculations also assess heat on a large scale without space constraints In order to implement the practicality of the simple formula for the thermal comfort of urban space this study will evaluate the thermal comfort of the elementary school pick-up area It also proposes a simple application for making thermal comfort map of urban area in different scales The thermal comfort map gives a optimization strategy and can also provide suggestions for urban residents to deal with thermal hazards
