Existing Building Wall Energy-Saving Reform And Research Of External Insulation Wall Defect Dealing

In severe-cold area and cold area in our country, the objective of Economizing Energy of Building mainly achieve by improve the heat-insulating property of the building envelope and the thermal efficiency of the heating installation, the building envelope has assumed60%of this task, and as the most biggest are of it the wall take more task, it plays a conclusive effect of the Economizing Energy of Building. In Jilin Province 《the Code of Domestic Architecture Energy Saving Design (saving65%)》 has been brought into operation from2008-01-01, it has made a higher demand to the thermal performance of the building envelope, so we need to adopt a homologue dealing measure in the cause of applicable. This topic aims to choose the applicable energy-saving technology, reasonable and energy saving measures, improve the energy saving effect.This topic investigate practical situation of residential building walls of Jilin province, analyzes and compares the external energy-saving materials and the technology, with the full study of the insulation, safety and construction methods etc, choose the appropriate programmer, computation and puts forward the measures of energy saving transformation wall and general, In Jilin province and the existing problems of EPS exterior insulation wall quality carried out extensive investigation, analysis and experimental research, and puts forward some preventive measures and solutions, By exterior insulation quality problems caused by the wall body hair (mildew), with the means of biological experiment analysis, research, and put forward the method of governance mechanism.This topic research aimed at saving transformation and defects treatment walls, improve the living environment and accelerate Jilin residential building comfort is energy-saving65%goal the realization, promote the development of building energy efficiency.
