由于近些年建筑业发展的非常迅速,我国的建筑能耗总量也日益增加,在能源消耗总量上的占比也由上世纪70年代的百分之十上升到了最近几年的百分之二十七,在我国的总能量中占比为25%~40%。所以,在当前这种全球能源短缺的情况下,节能有着非常重要的意义。我们国家很多地区的外围护结构耗热量较大的分项工程前三位是外墙体、门窗以及屋面。本文将对上述三个分项工程所使用的施工节能技术进行介绍。
Due to the rapid development of construction industry in recent years, the total amount of building energy consumption in our country is also increasing. The percentage of total energy consumption has also risen from 10% in the 1970s to the percentage in recent years Twenty-seven, in our country’s total energy accounted for 25% to 40%. Therefore, in the current global energy shortage situation, energy saving is of great significance. In our country, the top three of the sub-projects with large external heat consumption in many areas are exterior walls, doors, windows and roofs. This article will introduce the construction of energy-saving technologies used in the three sub-projects.
