Natural ventilation is a more pleasant and acceptable ventilation mode, which is favorable to human physical and psychological comfort and health. In this research, experiments and analysis on the fluctuant characteristics of natural wind in outdoor environment and in different positions of indoor area are conducted. The authors analyze the physical structure of airflow fluctuations with turbulence statistical theory, chaos and fractal theory. The fluctuant characteristics of the natural wind in different built environment are found and generalized in the paper.
