China building energy-saving potential in the end how much? Minister of Construction Wang Guangtao calculations account for people, he said that new strict enforcement of building energy-saving construction standards, the gradual implementation of the transformation of existing buildings, and in 2020, China is expected to save electricity each year degrees 420000000000 , saving 260 million tons of standard coal, reduce carbon dioxide and other greenhouse gas emissions by 846 million tons.

Wang Guangtao at the opening on the 28th "second session of the International Green Building Expo," said China is great potential for building energy-saving, new buildings completed every year for urban and rural area of nearly two billion square meters. Expected to be by the end of 2020, the National Housing construction area will add nearly 30 billion square meters. If the continuation of the current situation of building energy consumption, annual consumption of electricity and that two trillion 410 million tons of standard coal, nearly three times the current national energy consumption. Coupled with the production of energy-consuming building materials 16.7 percent, accounting for society as a whole 46.7 percent of total energy consumption.


According to the survey, the general public building energy consumption for unit of 20-60 degrees electricity, urban residential units is twice as energy-consuming; large public buildings unit energy consumption for urban residential 10-2 tenfold. Wang Guangtao said that the new construction strict implementation of building energy-saving standards, the gradual implementation of the transformation of existing buildings is expected to 2020, can save 420 billion per year of electricity and 260 million tons of standard coal. To reduce carbon dioxide and other greenhouse gases released 846 million tons.


Chinese Vice Premier Zeng Peiyan proposed, the building of a resource-conserving and environment-friendly society, China must vigorously develop land-efficient construction. The beginning of the new building energy efficiency standards must be strictly enforced. At the same time to strengthen the green building standards certification and promotion work. To energy conservation as a breakthrough point, and comprehensively promote water conservation, land and materials, to increase the overall construction of China's resource-saving, steady progress has been building energy-saving.
