Practice And Research On Energy-Saving Testing Technology For Exterior Wall Exterior Of Residential Buildings In Zhengzhou

In the 21 st century,the energy issue has become a major factor constraining social sustainable development and ecological environmental protection.China is a big country with energy consumption in buildings.Building energy consumption accounts for 20%-30% of the total energy consumption of the country,equivalent to 857 million tons of standard coal.The carbon emissions caused by the increase of greenhouse effect,seriously damaged the ecology.Environment and living environment.China's new construction area is more than the total new construction area in developed countries,and the building energy consumption is 2-3 times that of developed countries.The harsh climate and environment have affected the normal life of the people,affected the sustainable development of our country,and violated the basic national policy of building a conservation-oriented society.Building energy conservation needs to be resolved.How to reduce building energy consumption,how to improve energy utilization,etc.,around energy-saving issues,has become an important link restricting sustainable development.Among many building energy-saving methods,external wall insulation is a common insulation and energy-saving construction technology for residential buildings in Zhengzhou.This technology has significant effects on reducing building energy consumption,improving energy utilization,and improving living environment quality.This paper expounds the status quo of building energy consumption and building energy saving in China from the perspective of a building energy-saving tester and the significance of studying the energy-saving detection technology of external wall insulation;reviewing the relevant literature in recent years,conducting research according to scientific methods,living in Zhengzhou City The building wall insulation and energy conservation policy,the common wall materials in the external wall insulation system,and the common external wall insulation energy conservation system are summarized and analyzed respectively;the insulation performance of the building envelope structure and the detection technology of the external wall insulation materials are discussed;Combined with the case of Zhengzhou City residential building exterior wall insulation test,the case analysis of the insulation performance of the residential building envelope structure and the external wall insulation material detection technology in Zhengzhou City was carried out,and the solution was proposed according to the problem;combined with the actual engineering test case Suggestions for improvement from raw materials,construction technology,design and testing are given.Finally,suggestions and prospects for the development of external wall insulation and energy-saving detection technology in Zhengzhou City are given.It is hoped that through this paper,the promotion of energy-saving detection technology for exterior insulation of building exterior walls will be promoted,especially to promote the application of energy-saving detection technology for external wall insulation in cold regions similar to Zhengzhou City,to promote awareness of energy-saving and emission reduction,and to contribute to the country's ecological civilization construction.
