Abstract
The outdoor wind environment is one of the most important factors influencing the biological environment and human comfort. The campus of China University of Mining & Technology (Beijing) (CUMTB) is the case study for this research. PHOENICS simulation software was used to carry out a numerical simulation study of the outdoor wind environment. The pedestrian‐level wind (PLW) environments for both winter and summer were investigated. Based on the numerical simulation results, the overall evaluation and subregional analysis of the campus’ current outdoor wind environment were carried out. Then, according to the results and problems of wind environment assessment, improvement measures and strategies of outdoor wind environment in universities are proposed from the aspects of campus planning, single building form, and greening configuration. The main goal is to further improve the outdoor space and environment of universities in Beijing and provide general guidelines to improve the quality of the universities’ wind environment effectively. The strategies can provide a reference for the same type of campus on wind environment renovation and improvement. This study can also provide data support and reference significance for outdoor thermal environment/pedestrian environment research.
Highlights
With the rapid development and continuous expansion of enrollment in universities in China, high-density university campus space has grown rapidly, and campus environmental problems have increasingly become more prominent; the overall performance of natural ventilation in the campus is poor
southeast wind (SE): southeast; north-northwest wind (NNW): north-northwest, according to the definition of wind direction, the wind direction of the wind blowing from the azimuth angle in the range of 337.5° ± 11.25° is recorded as NNW
PHOENICS software contains a variety of turbulence models, including DNS, Large Eddy Simulation (LES), and Reynolds Average Navier–Stokes (RANS)
Summary
With the rapid development and continuous expansion of enrollment in universities in China, high-density university campus space has grown rapidly, and campus environmental problems have increasingly become more prominent; the overall performance of natural ventilation in the campus is poor. Campus planning, building layout, building form, and landscape setting are important factors affecting the outdoor PLW environment. Erefore, it is of great significance to evaluate and improve the PLW environment in universities by fully considering the campus planning, building form, landscape setting, and so on. Many university campuses are short of land, densely built, and overloaded in Beijing, which leads to environmental problems such as difficult diffusion of pollutants, wind whirlwinds in winter, and lack of ventilation and heat dissipation in summer. Is study has further improved the quality of the campus environment through numerical simulation and analysis and has provided guidelines for the campus planning, renovation, and green campus construction It can provide basic data support and reference significance for outdoor thermal environment and pedestrian environment research
