Research on Healthy Wind Environments of Settlements Based on Epidemic Control: A Case Study of the Lingnan Yuedao Settlement

With the evolution of the coronavirus epidemic, the health problems of settlements have attracted broad attention. In the present study, a systematic study of the design of healthy wind environments of settlements based on epidemic prevention situations was carried out through a literature review, field investigation, on-site measurements, numerical simulations, and other methods. The necessity to design healthy wind environments in settlements was established based on the literature review focusing on coronavirus epidemic control and healthy settlements. A case study of the Lingnan Yuedao settlement was carried out through a field investigation and on-site measurements. The specific requirements were summarized by combining relevant guidelines and standards for the healthy wind environments of settlements. On this basis, numerical simulations, benchmarking judgments, and systematic analyses from community, group, and individual perspectives in the Yuedao settlement were performed with Phoenics software. It was found that all three levels suffer from numerous problems, such as poor ventilation, air pollution, etc. Subsequently, the optimization, simulation verification, and reassessment of these problems were conducted. Finally, it was concluded that the design of healthy wind environments in a settlement should be oriented to green spaces, intelligence, and health, with consideration given to local conditions and sustainable development while preventing and controlling the epidemic.
