Effects of thermal environment and air quality on outdoor thermal comfort in urban parks of Tianjin, China.

The comfort level of outdoor thermal environments is affected by several factors. Previous studies of thermal comfort have generally investigated the main microclimatic factors as dependent variables, such as the temperature, wind speed, humidity, and thermal radiation, but the influence of the air quality has rarely been explored. In this study, we acquired meteorological element observations and conducted questionnaire surveys in Peach Blossom Park, Hebei University of Technology, and Xigu Park in Tianjin.

Field measurement and numerical simulation of the relationship between the vertical wind environment and building morphology in residential areas in Xi'an, China.

The inadequate consideration of the impact of building morphology on ventilation efficiency in many urban residential areas has resulted in a series of environmental problems that threaten human health. The purpose of this paper is to establish a predictive model between ventilation efficiency and building forms in residential areas. First, the characteristics of the vertical wind profile in residential areas were measured using unmanned aerial vehicle (UAV).
