Simulation Of Dynamic Energy Consumption Of Container House Building Based On Future Climate Situation In Guangzhou

With the increasing frequency of international trade,a large number of containers are exposed to the risk of retirement because of the annual Rain Water erosion and collision in the course of transportation.The idea of recycling waste containers idle in ports has been put into practice by more and more architects.The characteristics of prefabrication and modularization of container buildings and the low cost and environmental protection value compared with traditional buildings have attracted more and more attention.On the other hand,urban construction is changing with each passing day,harmful gases and carbon dioxide emissions are increasing,which makes the global temperature frequent natural disasters,resulting in the destruction of human living environment.Because the past climate data are used to analyze the building energy consumption at this stage,it is impossible to predict the future energy consumption change trend caused by climate change.To sum up,it is necessary to study the energy consumption trend and the corresponding energy saving strategy of container residence in the future climate situation.The content of this paper is divided into four parts: the first part is the basic research of container residence,from analyzing the development course and structure composition of single container,gradually deepening to the combination research of container residence.Based on its characteristics and application direction,the construction and heat insulation requirements of container house in Guangzhou area,the development of domestic container house and case investigation,the potential value of developing container house in Guangzhou area is excavated.The second part analyzes the production method of typical meteorological year at home and abroad,downloads the historical meteorological data of Guangzhou area2004-2018 through Climate.One Building database,and makes the new typical meteorological year by selecting the international typical meteorological year.Future meteorological data are predicted SRES A2 the new typical meteorological year.In the third part,the dynamic energy consumption simulation analysis method is used to simulate the energy consumption of the container house,and the energy consumption of the typical meteorological annual documents in the past,present and future three time periods in Guangzhou area is compared.Then the database data were selected to compare with the energy consumption simulation results in 2080,and it was found that the large increase of the net thermal of envelopes structure and permeable ventilation was the reason for the increase of refrigeration energy consumption in summer.The fourth part puts forward the corresponding energy saving strategy,First of all,the heat transfer of each part of the envelopes structure in the summer of 2080 is analyzed,That the area of the south window should be increased,The conclusion that the remaining three facing window areas should be minimized.After that,the parametric study on envelopes structure,indoor thermal disturbance,infiltration ventilation of container house,Energy saving up to 6% by changing wall insulation material;Energy saving up to 4% by changing the material of the outer envelopes of the box;By changing the shading coefficient,17.7% of the energy can be saved;by changing the number of indoor thermal disturbance,the average energy can be saved by 11%per person,and by changing the number of infiltration ventilation,2.8% energy can be saved per 0.25 h/times.
