Cities are an important source of greenhouse gas emissions, extremely vulnerable to the impact of climate change, and are a key place to deal with climate. Street, as one of the most basic and important space of urban functions and daily life, is a main component of city master plan related to organic activities. The purpose of this study is to analyze street microclimate environment and thermal comfort environment using ENVI-met program(V4.4.6 Summer 21), through changing street direction including North-South(N-S), Northeast-Southwest(NE-SW), East-West(E-W) and Southeast-Northwest(SE-NW) based on field measurement results. The results of this study were as follows: Mutual shading from adjacent buildings have a greater impact on outdoor thermal environment especially in day time. At 13:00, the values of air temperature, mean radiant temperature, wind speed and comfort index in N-S and NE-SW street are greater than other two directions due to a lack of shading area. In addition, mean radiant temperature and comfort index of E-W street are more sensitive after sunrise and before sunset, but it shows less obvious on air temperature and wind speed. All of streets are "Very hot" level from 10:00 to 16:00, time duration of E-W street is longer than other three directions, and the highest mean radiant temperature and comfort index of NE-SW street are appeared at 14:00 that one hour later than other three directions. Shading of trees for microclimate environment is weaker than mutual shading from buildings. It is recommended that the main streets are more consistent with the prevailing wind direction in planning of new city.
