随着城市建设的高速发展,我国的建筑能耗逐年大幅度上升,已达全社会能源消耗量的32%,加上每年房屋建筑材料生产能耗约1 3%,建筑总能耗已达全国能源总消耗量的45%。我国现有建筑面积为400亿m2,绝大部分为高能耗建筑,且每年新建建筑近20亿m2,其中95%以上仍是高能耗建筑。如果我国继续执行节能水平较低的设计标准,将留下很重的能耗负担和治理困难。庞大的建筑能耗,已经成为国民经济的巨大负担。因此建筑行业全面节能势在必行。
With the rapid development of urban construction, building energy consumption in our country has risen sharply year by year and has reached 32% of the total energy consumption of the whole society. Coupled with the annual energy consumption of building materials production of about 13%, the total building energy consumption has reached the national 45% of total energy consumption. China has an existing building area of 40 billion m2, the vast majority of which is high-energy-consumption buildings. In addition, nearly 2 billion m2 of new buildings are built each year, of which over 95% are still high-energy-consumption buildings. If China continues to implement the lower energy-saving design standards, it will leave a heavy burden of energy consumption and governance difficulties. Huge building energy consumption has become a huge burden on the national economy. Therefore, full energy-saving construction industry is imperative.
