目前,我国每年新建20亿平方米建筑,85%以上为高能耗建筑;441亿平方米存量建筑中,95%以上是高能耗建筑。而更让人惊骇的是,我国单位建筑面积能耗是发达国家的二至三倍!随着越来越多的农村人口迁移至城镇居住,购置大面积住房的人群必然呈增加趋势,这样大规模的建筑必然导致能源消耗的进一步上升。在这种情况下,提倡建筑节能,大力发展绿色建筑就显得尤为必要。 At present, China annually builds 2 billion square meters of buildings and over 85% of them are high-energy-consumption buildings. Over 95% of the 44.1 billion square meters of inventories are high-energy-consumption buildings. Even more shocking is that China's energy consumption per unit of floor area is two to three times that of developed countries! As more and more rural residents migrate to cities and towns, the population purchasing large-area housing will inevitably show an upward trend, Large-scale construction will inevitably lead to further increases in energy consumption. Under such circumstances, it is necessary to promote building energy conservation and vigorously develop green building.
