目前,建筑能耗同工业能耗、交通能耗并列成为我国能源消耗三大“能耗大户”。其中,建筑能耗约占全社会总能耗的30%。据相关数据显示,在我国近20亿平方米的新建建筑中,高能耗建筑超过95%以上。随着城镇化进程的加快,能耗的逐步增长,能源效率已成为我们不得不重视的现实课题。近年来国家在提倡要建设资源节约型、环境友好型社会,大力倡导发展绿色、环保、可再生能源等方面的新型产业。国家“十二 At present, the building energy consumption and industrial energy consumption, transportation energy consumption side by side as China’s energy consumption three ”big energy consumption “. Among them, the building energy consumption accounts for about 30% of the total energy consumption of the whole society. According to relevant data, in our country nearly 2 billion square meters of new buildings, high-energy buildings more than 95%. With the acceleration of urbanization and the gradual increase of energy consumption, energy efficiency has become a realistic issue that we have to pay attention to.
