Research of Application of Passive Natural Ventilated Strategies of High-Density Urban Area

High-density development is becoming an inevitable tendency in Chinese urbanization. In this study, the application of natural ventilation in high-density urban development is discussed. Based on the domestic and foreign study on natural ventilation, indoor and outdoor natural ventilated strategies, and the application on natural ventilation in underground space development are analyzed. From the study, the relationship between passive and active ventilated technologies is interpreted into what is described to be synergistic, complementary and additive.
