【 摘 要 】

The outdoor thermal environment of the underground parking system of a residential area in Nanjing, China is simulated using ENVI-met software for three planning schemes in which underground space is not used, partly used, and fully used. The scale of underground space development is found to affect the outdoor thermal environment. The quality of the outdoor thermal environment is best when the underground space is fully used. Compared with the situation where underground space is not used, the partial use of underground space reduces the wind speed by up to 0.09 m/s, reduces the air temperature by up to 0.5 °C, and increases the relative humidity by up to 3%, whereas the full use of underground space decreases the wind speed by up to 0.33 m/s, reduces the air temperature by up to 1.1 °C, and increases the relative humidity by up to 5%. The use of underground space is shown to improve the ecological environment of the residential area and enhance the quality of the outdoor thermal environment.
