According to nanometer rubber and plastic board manufacturers, green buildings refer to buildings that implement stricter energy consumption standards from design to operation in terms of water saving, land saving, energy saving, material saving and environmental protection. According to han aixing, deputy director of the department of building energy conservation and science and technology of the Ministry of Housing and Urban-Rural Development, China's green buildings have been developing at a rate of doubling every year for the past five years, with a total area of green buildings of nearly 163 million square meters by the end of 2014. The following is an analysis of the future development trend of green building materials in China.
The "green" of building materials is quietly happening, energy saving, environmental protection and lightweight building materials are becoming the development trend. According to the national plan, green buildings in China's cities and towns will account for 50% of new buildings by 2020, up from 2% in 2012.
In the past, it is difficult to find common building materials such as exterior wall bricks and mortar. Instead, it is a variety of new products and new technologies of building energy saving and new building materials, including energy-saving insulation materials, new paint and waterproof materials, green energy-saving building technology solutions.
"The huge market demand is pushing the industry to innovate." The deputy secretary-general of the China association of building energy conservation Zou Yanqing said that green building has risen to national strategic height, in 2014 countries in the aspect of building energy efficiency investment will exceed 4 billion yuan, in 2015, the new green building area of 1 billion square meters, 2020 China urban green building accounted for the proportion of new buildings will rise to 50%.
Relevant reports from China show that more than 95% of the existing buildings in China are high energy consumption buildings, and the energy consumption level lags far behind the advanced international level. Take heating for example, the primary energy consumption of central heating in China is 20 kg standard coal/square meter, which is one time higher than that of European countries in the same latitude.
According to the requirements of the country green building action plan, this year, the government investment in building, such as schools, hospitals, museums, science and technology museum of municipality directly under the central government, cities under separate state planning and capital cities of affordable housing and monomer building area of more than 20000 square meters of large public buildings such as airport, station, will comprehensively implement the green building standards.
