Study Of Xinjiang Yining Residential Building Envelope Energy Saving Transformation And Construction Technology

Construction industry, traffic, is the three largest energy consumption, building energy consumption accounts for about30%of total energy consumption, buildingenergy consumption, air conditioning and heating energy consumption accountsfor30~50%. Therefore, the amount of energy consumed for heating in winter inmost areas of North China is huge, the environmental pressure is enormous. Inthe building through the heat dissipation structure accounted for70of totalenergy consumption to80%, so by building "coat" to reduce the overall energyconsumption of buildings has become the focus of the construction of energy-saving work.In the promotion of national technology policy in China and energy savingstandards, technology developed in external wall insulation, insulation materials,insulation variety are also appeared, accompanied by the relevant problems ofheat preservation system also appeared. For some first-tier cities, capital of theregion of external thermal insulation material selection, construction method isrelatively mature, but some problems still exist in the area.According to "the relevant information in Yili Kazak Autonomous Prefectureconstruction applications of renewable energy demonstration city" Yili Kazak Autonomous Prefecture of Yining city in2011April statistics show that Yining existingpublic buildings about3500000square meters, existing residential constructionarea of about12500000square meters; that is to say, both the construction ofhuge, through the transformation of benefits is not to be ignored, this paper takes Yining city as the research area, the regional climate characteristics andcultural needs and many other point of view, the technology of external thermalinsulation and heat preservation technology were compared, and combined with the local situation, summarized Yining city is more suitable for the externalinsulation technology, research status and the Yining area of external insulation ofexterior wall and the existing problems, In order to solve the problems and givethe corresponding recommendations, countermeasures; and through cases for anengineering analysis in Yining City, discusses the exterior insulation systemin the Yining area of operation. In view of the situation and the local abundantsolar energy resources and groundwater resources and distribution of heatingarea of Yining City, put forward in the end, hope that through the transformationof the network and improve the utilization of renewable energy proportion, in orderto achieve the Protect environment, energy saving target.
