雾霾来了,沙尘暴起了……我们对城市环境的关注,从来没有像今天这样急迫。世界上有一半的人口居住在城市,城市创造了80%的GDP,同样也消耗了85%的资源和能源,排放了85%左右的废弃物。而在中国,建筑物总能耗占社会总能耗的25%～28%,建筑物二氧化碳排放占总排放量的40%。我们居住的房子绿色、环保吗?怎样给地球和自己一个绿色的空间和未来? The haze came and the dust stormed... Our concern for the urban environment has never been more urgent than it is today. Half of the world’s population lives in cities. Cities create 80% of GDP, 85% of resources and energy, and 85% of waste. In China, the total building energy consumption accounts for 25% to 28% of the total social energy consumption, and the building’s carbon dioxide emissions account for 40% of the total emissions. Is the house we live in green and environmentally friendly? How can we give the earth and ourselves a green space and future?
