Research On Energy Saving Of Large-scale Translucent Roof In Buildings

With the rapid development of the world economy,the modernization process has advanced by leaps and bounds,and the demand for energy is increasing.At the same time,the accelerated depletion of traditional fossil energy sources and the environmental pollution caused by these energy sources have caused human beings to face increasingly serious energy and environmental crises.In the whole society,s energy consumption,the proportion of building energy consumption in total energy consumption is about 25%to 45%,and the proportion of building energy consumption in developed countries is larger than that in underdeveloped countries.At the same time,building energy consumption is a consumer energy consumption.Compared with productive energy consumption,consumer energy consumption is wasteful except for the part that guarantees normal consumption.Therefore,in today’s world where energy issues are becoming more urgent and building energy consumption is growing,countries around the world have listed building energy efficiency as a priority in energy conservation.Among all kinds of buildings,public buildings have always been energy-consuming because of their large size,unique shape and special functions.The energy consumption of public buildings is 2-3 times that of ordinary buildings,so public buildings are the main direction of building energy conservation.Among them,such as the terminal building,swimming pool and other buildings,due to the design needs to use a large amount of lighting roof,the use of natural lighting to make the indoor light environment to be improved and the building’s appearance is beautiful.However,lighting roofing also brings about high energy consumption.At the same time,the light-transmissive roof makes the sunlight shine into the room,which has a great influence on the indoor tenperature stability,the indoor temperature fluctuation is large,and the peak load of the air-conditioning system is high.This topic selects a marine paradise located in Changchun City in Northeast China as the research ob.ject of building energy conservation.The indoor marine park is equipped with wave pools,water parks,hot spring areas and various water amuselent facilities.The indoor height is 25-35 neters.It is a typical high-rise space building.The roof of the building is planned to adopt a curved large-scale glass roof.outdoor.The climate has a great impact on the indoor environment and energy consumption of buildings.In winter,the outdoor temperature is low.the indoor humidity is large,and the condensation on the light-transmissive roof is also caused,which reduces the comfort of the room.This paper intends to study the heat transfer characteristics of large-area light-transmissive roofs,to explore the impact of large-volume translucent houses on indoor environment and energy consumption,and propose solutions to reduce roof energy consumption,calculate and compare various schemes,and select better ones.The solution is applied in engineering practice to reduce the building energy consumption and reduce the operation and maintenance costs of the building.
