Optimizations Of Underground Parking Layout Of Residential In Cold Regions Based On Improving Air Quality

With the accelerating process of urbanization, intensive use of land becomes a popular trend. Development and utilization of underground space are becoming increasingly diverse. However, as the increased of ounership of cars, the construction of underground parking of residential has become a stereotype. Underground parking space has the characteristics of high-closed space, long-term no natural light, cold, wet and poor ventilation. All the characteristics results in the health and safety of people who use the parking space facing the threat from air pollution.This study aims to analyze the air quality of underground parking space in residential of cities in cold region, and to provide optimizations of underground car parking to improce its air quality. As there is no relative standards or management practices in our country, this study provids a theoretical basis and data for residential underground parking space in the future. At the meantime, the optimization this study proposed for underground parking space will become the theory and practise of the design in the future.This study, at first, reviews the domestic and international underground parking air quality studies, which lays a solid foundation for the full text of the background research; secondly, researches the theories of air quality, pollutants and pollution characteristics of underground parking space and fluid dynamics, which lays a theoretical foundation for further study; at last, through the measurement and analysis of residential in cold region underground parking air quality, provides some specific strategies and optimizations. This study used literature research methods, experimental research methods, interdisciplinary research methods and other research methods. The optimizations this study proposed will lead residential underground parking in cold region to healthy and Low Carbon.
