Study On Energy Saving Design Of Underground Garage In Residential Area In Cold Area

In recent years,with China’s economic developing,the increasing requirement of life,the number of private cars is increasing.and t he garage needs is increasing.Limited land resources can not meet the demand of people’s life.Underground resources development has become a practical and feasible method.The underground garage as an important part of the residential district,supporting facilities lighting,ventilation system,etc included.Although have solved the problem of surface space utilization underground garage,but because of the particularity of its environment,its form a complete set of related systems,also has brought the huge energy consumption,such as electricity.In response to the call of national building energy saving,reasonable use of natural resources,improve the physical environment of the underground garage internal to make it more comfortable,reduce energy consumption,to maximize the utilization of natural resources,has become a development direction.So,I believe that the residential district underground garage energy saving development to achieve the goal of reducing building energy consumption is of great significance.By several residential area underground garage of field investigation,summarizes the classification in the lighting and ventilation and heat preservation,and the underground garage classification analysis,namely the underground garage,underground garage and underground garage open problems of natural lighting and ventilation and heat preservation.Energy-saving optimization measures are put forward to solve these problems,to provide more reliable basis.Suitable for cold region residential area underground garage of natural lighting and ventilation and heat preservation of the main design methods are: can breath double wall,atrium,subsided courtyard,light inlet window well,light pipe with solar air collector and other technical measures.Choose cold region is located in the middle of Shenyang of Lliaoning area for the preparation of the residential area of the underground garage energy-saving design practice as the research object,using "subsided garden,solar chimney,can breath double wall,reflectivity big wall surface decoration materials,ground regenerator,light guide and lighting atrium" comprehensive measures such as to strengthen the natural lighting and natural ventilation;Use additional,daylighting cap between the sun and walls,roof and floor for an underground garage design measures to strengthen heat preservation and heat insulation.Combine many lighting and ventilation and heat preservation measures to strengthen and considering the influence of the climate characteristics of cold regional residential area and the characteristics of the underground garage.In addition,after using the Ecotect software and Fluent to energy-saving design scheme in natural lighting,natural ventilation and thermal aspects of computer simulation and analysis,provide data support for energy saving design scheme.Sums up the suitable for cold region residential area of the underground garage building energy-saving technical measures.
