Study On Selection And Optimization Of External Wall Thermal Insulation Material For High-rise Residential Buildings In Xi'an

Our country's accession to the Paris Climate Change Agreement on 3 September2016,it means that the Government has placed energy conservation and emission reduction at a high political level.Although China is a big energy reserve country,it has always been a big energy consuming country because of low energy utilization.With the continuous increase of industrialization level and economic index,the annual consumption of standard coal in China has exceeded the total production.From a political and economic point of view,energy conservation and emission reduction all play an important role.As a pillar industry,building energy consumption is increasing year by year.For high-rise residential buildings with the largest area proportion,strengthening the heat loss of outer walls has become a major research topic.Based on the status quo of high-rise residential buildings in xi 'an,this paper starts from the thermal insulation performance and fire performance,and hopes to find a balance between them through research and analysis.First elaborated our country the latest code for fire protection and energy saving75% standard requirements,for different s residential exterior insulation situation of xi'an region research,analyze the present situation of xi 'an area residential building insulation and through a questionnaire survey,delving into its formation reasons and provide the basis for material selection of later,to ensure that can be implemented.Secondly,the site investigation of fireproof window manufacturers in xi 'an market was carried out to comprehensively understand the composition,performance,test report and price of fireproof window,and the detailed construction map of class B1insulation materials and the insulation system outside fireproof window walls was drawn to guide the on-site construction.Finally,the common high-rise residential housing type in xi 'an area is selected as an example to calculate the cost of the new insulation system,calculate the impact of different window areas on the incremental cost,and put forward the optimization plan according to the actual case,so that the designer and the construction party can choose.
