Research On Energy-saving Design Of Building Exterior Protection In Hot Summer And Cold Winter Area

The rapid growth of China's construction area and the increasing demands of the indoor environment have consumed huge amounts of energy.Based on such a background,the popularization of building energy-saving design will make an important contribution to China's energy-saving emission reduction.In the hot summer and cold winter areas,the building area is vast,and the potential for promoting building energy conservation is enormous.Taking the Anhui area as an example,the author analyzes the effect of peripheral energy-saving design on reducing building energy consumption from factors such as climate characteristics and architectural design.This paper mainly analyzes the energy-saving design and optimization of building exterior protection and the evaluation of building energy consumption in combination with the actual project of Huaibei,Anhui Province,and uses the least squares method to fit the relationship between the building cold load and the year-by-year relationship.Firstly,according to the different peripheral protection energy-saving design schemes,starting from the factors affecting the external protection energy-saving factors,theoretically,the main parameters such as heat transfer coefficient,thermal inertia index and condensation temperature are calculated.Then use PKPM energy-saving design software to carry out the external protection energy-saving design of the project,compare the energy consumption between the design building and the reference building,and guide the energy-saving design optimization plan according to the energy consumption evaluation result.After optimizing the design of the building,the results showed that the relative energy saving rate increased by 7.89%.In addition to energy consumption assessment,temperature field analysis is performed on the lowest point of the wall surface temperature to avoid condensation.Finally,the hourly cold load data of the building will be designed,and the least square method will be used to solve the relationship equation,predicting the trend of future building cooling load,which is conducive to equipment selection,energy saving and emission reduction in the building operation process,and improvement of equipment utilization.The guidance of the rate.This paper hopes to further reduce the building energy consumption and improve the energy consumption of the hot summer and cold winter areas by studying the energy-saving design of building exterior protection and combining the development of new energy-saving technologies for external protection at the current stage.Design.Figure[36]table[29]reference[50]...
