Research On Design Of Open Underground Garage In Residential Quarter From Health Perspective

In recent ten years,the number of cars has increased with people’s living standards,and cars have gradually become the main means of transportation.With the increasing demand for parking space,the attached underground garage in residential areas has become the mainstream parking space in the face of the increasing scarcity of urban land resources.Under the background of increasing health concerns,the closed,dark and humid underground garage environment is difficult to meet people’s expectations for a better life.The research goal of this paper is to build a healthy,comfortable and environment-friendly underground garage to adapt to the development of the times with the design concept of open underground garage.This paper is based on the research and application of open underground garage design in residential quarters from the perspective of health.Through project research,the demand for underground garage design is analyzed and summarized from the perspective of residents’ use experience and property operation.Aiming at the core problems of insufficient brightness,poor air quality and high power consumption raised by residents and properties in the survey and interview,the design concept of open underground garage is proposed to open the closed basement,let natural light assist artificial lighting,and let natural ventilation assist mechanical ventilation,so as to create a healthy,comfortable and environment-friendly underground garage environment.This paper summarizes the design methods of four open underground garages,and provides reference and inspiration for the design of open underground garages in China through the application of specific cases.The study is divided into three parts.The first part raises questions,including the first chapter.Under the background of land shortage,car use surge and health demand,the research adopts the literature analysis method to find that the underground garage has a large demand for use,while the underground garage has long had energy consumption problems,brightness and air problems,which can not bear people’s health needs in the new era.It has great potential in the design and research of underground garage from the perspective of health.Therefore,the thesis chooses "the design of open underground garage in residential area from the perspective of health" as the research object.The second part analyzes the problem,including the second and third chapters.First of all,the development and evolution of parking in residential areas are reviewed.The deep buried and closed underground garage cannot obtain natural ventilation and lighting.From the perspective of health,three important evaluation indicators of healthy basement are sorted out from the specifications and literature: the illumination of healthy underground garage is required to be above 75 lx,the humidity is below 70%,and the co concentration is not more than 30 ppm.In the field garage survey,based on the actual measurement of indicators and feedback from residents and property,three core issues of insufficient brightness,poor air quality and high energy consumption of underground garage were summarized.The third part is to solve the problem,including the fourth and fifth chapters.Taking the open underground garage as the design goal,the design methods of basement lifting,side high windows(holes),sunken courtyards,lighting and ventilation skylights are summarized,and the four use strategies of open underground garage are summarized.Taking Tianjun Garden as an example,the design strategy in Chapter 4 is used to optimize the opening of the underground garage,and the software performance simulation is used to obtain the opening optimization.After that,the natural ventilation and lighting supplement the mechanical ventilation and artificial lighting,with better effect and lower energy consumption.Finally,it is concluded that the open underground garage is an effective solution to balance the needs of vehicles,health needs and green sustainable development.
