Study On The Natural Lighting Design Of Underground Garage In Residential Area Of Hunan

In the rapid development of urbanization today,the scale of the construction of the city are constantly expanding,urban space in the construction of the building as a puncture needle,the city population surge,residential areas also take place,living area underground garage drastic construction,occupy Underground space a large proportion.After the preliminary investigation and rough field investigation,it was found that there were still many problems and shortcomings in the construction of the underground garage in the residential area of Hunan Province.The lighting and ventilation of the vast majority of the underground garage were artificial lighting and mechanical ventilation.Is the design of underground garage in some residential areas in the natural lighting awareness,but in the absence of low-cost and high efficiency of the natural lighting of the theoretical technical support and nowadays the construction of underground garage in the basic use of active lighting ventilation,cost a lot of construction costs And its late use and maintenance costs,from the perspective of building users,the effect is not ideal for artificial lighting and did not bring more comfortable underground garage use space,underground building lighting research lag,inevitably affect the living Environmental quality of underground garage.Therefore,this study takes the underground garage of Hunan residential area as the research object,through the field investigation of the residential area of Meixi Lake and Yanghu area in Changsha City,the statistical analysis of the underground garage of the existing residential area,and the influence of the light environment problem The basic model of the underground garage is simulated according to the climate,geographical features and norms of Hunan Province in order to obtain the light and geography characteristics of the Hunan area.Natural lighting methods and parameters recommended value.Combined with the vertical design and greening and landscape of the site,the basement and its environment in a variety of spatial elements combined,in accordance with the use of different types of underground space requirements,fully consider the sunshine,heating and air conditioning,landscape vision,spatial recognition and other needs,And put forward a number of underground space ecological design strategies for the climatic and geographical features of Hunan.
