Abstract: As a special administrative region of China, Hong Kong's financial, trade and commercial status is at the forefront of the world. At the same time, Hong Kong is also one of the cities with the highest population density in the world, with typical high building density and high population concentration, facing the problem of heat island. The rise of urban temperature and the enhancement of urban heat island effect will increase human thermal stress in urban space and affect people's overall well-being.
This study selected the sidewalks on the left and right sides of designated streets in Hong Kong as the research object, adopts literature research, simulation model, control variable method and other methods to study street-level (street canyon orientation, street building height sh) and neighborhood-level (urban layout, building density, building height) two levels of influencing factors. The ENVI-met software is used to simulate the thermal environment comfort of the designated area on the designated date. Microclimate elements such as temperature, humidity, solar radiation, wind speed, and wind direction were obtained, and the physiological equivalent temperature (PET) was used as the thermal comfort index. The PET value was calculated by Biomet, and then the thermal comfort of the sidewalk area was analyzed and discussed.
The study explores the influence of the thermal environment influencing factors at the neighborhood-level and street-level of designated streets in Hong Kong on the thermal comfort of the sidewalk area through microclimate simulation analysis, which is practically significant.
