Research Of External Insulation Energy Saving Reconstruction Technology Of Shandong Existing Building Exterior Wall

With the rapid development of our Chinese national economy and the increasing of energy consumption, energy problem has becoming one of the main factors of constrainting it sustainable development. Shandong Province is a large consumption of energy, building energy consumption account for quarter of the total energy consumption. Shandong Province has large quantity of high energy-consuming existing building, thermal performance of these existing buildings exterior walls is poor, carry out the external insulation energy saving reconstruction of Shandong existing building exterior wall is one of the important ways to reduce building energy consumption.The paper has studied on external insulation energy saving reconstruction technology of Shandong existing building exterior wall. First, by means of visit, investigate present situation of Shandong Province existing building exterior walls and the quality problems of exterior wall outer thermal insulation.By means of test, quantitative compares the thermal performance and status of energy consumption of existing building. Described necessity of external insulation energy saving reconstruction of Shandong existing building exterior wall.Second, according to actual situation of Shandong Province, puts forward suitable insulating ways and external thermal insulation system,and deeply analyzes characteristics, application range, system construction and construction technology. Studied deeply key teconologies of external insulation energy saving reconstruction of Shandong existing building exterior wall, puts forward exterior wall treatment measures of existing buildings and binding mode of thermal insulation material and exterior wall. Deep analysis the reason of cracking and fire, puts forward measures of crack prevention and fire prevention. Meanwhile, according to deficiency of the joint construction design, puts forward improvement measures.Finally, applied research results to Shandong Province external insulation energy saving reconstruction of existing housing and office building. By means of thermal testing and dynamic simulation to make quantitative analysis for external insulation energy saving reconstruction of existing building exterior wall,good effect got.The paper by means of research of external insulation energy saving reconstruction technology of Shandong existing building exterior wall and example of external insulation energy saving reconstruction,can provide support for the work of the external insulation energy saving reconstruction of Shandong existing building exterior wall, make contribution to the work of building energy saving of Shandong province.
