据相关数据显示,在我国能源问题越来越突出的背景下,我国寒冷地区冬季建筑采暖能耗已超过全国平均能耗约27%,同时也占该地区总能耗的30%~40%,不符合建筑节能相关政策。建筑围护系统是一种可以进行建筑内外物质、能量以及信息交流的媒介,而寒冷地区建筑围护体系是确保其采暖能耗不流失的主要保证,因此,提高寒冷地区建筑围护系统功能关系到寒冷地区建筑节能的效率。外墙保温可以提高建筑围护体系的保温隔热性能,但是由于目前建材市场保温技术品种、材料以及厂商的差异,性能和质量无法得到保证,因此在寒冷地区需综合考虑多方面因素而挑选建筑外保温设置的最优方法,改善寒冷地区的建筑节能效果。
According to the relevant data, under the background of the energy issue becoming more and more prominent in our country, the heating energy consumption of winter buildings in the cold area of our country has exceeded the national average energy consumption by about 27%, and also accounts for 30% -40% of the total energy consumption in the region. Does not meet the building energy-saving policies. Building envelope system is a medium that can carry out the exchange of material, energy and information inside and outside the building, and building envelope system in cold area is to ensure that the heating energy consumption is not lost the main guarantee, therefore, to improve the function of building envelope system in cold areas Efficiency of building energy efficiency in cold areas. External wall insulation can improve the thermal insulation performance of the building envelope system, but because of the current building materials market insulation technology varieties, materials and manufacturers differences, performance and quality can not be guaranteed, so in cold areas need to consider a variety of factors and select the building The best way to set thermal insulation is to improve the building energy efficiency in cold areas.
