建筑是社会主要的能耗行业,它比其他任何行业使用更多能源,是影响气候变化的主要因素。在我国,建筑能耗占据了总能耗的30%,建筑用能对全国的温室气体排放“贡献率”已经达到了25%。中国的既有建筑存量达440亿平方米,而且大部分不节能,随着建筑总量的不断攀升和居住舒适度的提升,建筑能耗还将继续上扬。因而加快建筑的绿色转变对于节能减排、缓解全球变暖的意义十分重大。
Building is the dominant energy sector in the community, and it uses more energy than any other industry and is a major factor in climate change. In our country, building energy consumption accounts for 30% of the total energy consumption, and the contribution of construction energy to the nation’s greenhouse gas emission has reached 25%. China’s existing building stock amounts to 44 billion square meters, and most of them are not energy-efficient. With the continuous rise in the total amount of buildings and the improvement of living comfort, the building energy consumption will continue to rise. Therefore, accelerating the green transformation of buildings is of great significance for saving energy and reducing emissions and alleviating global warming.
