1.中国城镇化与建筑耗能 China's urbanization and energy consumption by buildings 每年约有1200万~1500万人从农村移民到城市,从现 在开始将转移5亿人口 About 12-15 million people will migrate from rural areas to urban areas each year From now, 500 million people will migrate 每个城镇人口平均耗能水平为农村人口的3~3.5倍 Each urban population consumes energy 3-3.5 times as much as by rural population

From now, 500 million people will migrate. • 每个城镇人口平均耗能水平为农村人口的3～3.5倍 Each urban population consumes energy 3~3.5 times as much as by rural population
1.中国城镇化与建筑耗能 China's urbanization and energy consumption by buildings 每年约新建20亿平方米建筑 2.0 billion square meters of buildings are built each year 现有440亿平方米存量建筑中,绝大部分是高耗能建筑 Most of the existing 44 billion square meters of buildings in stock are high-energy-consuming buildings
