Low-energy and energy-saving buildings lead the new direction of environmental protection in China

With the rapid development of urban construction, China's building energy consumption has increased significantly year by year, reaching 32% of the total social energy consumption, plus annual energy consumption of building construction materials is about 13%, and the total energy consumption of buildings has reached the national level. 45% of total energy consumption. The huge energy consumption of buildings has become a huge burden on the national economy. Therefore, comprehensive energy conservation in the construction industry is imperative. China needs to take a resource-saving and environment-friendly new industrialization road. The first thing that cannot be ignored is building energy conservation. Comprehensive building energy conservation is conducive to fundamentally promoting energy resource conservation and rational utilization, alleviating the contradiction between China's energy resource supply and economic and social development; facilitating the development of circular economy and achieving sustainable economic and social development; and conducive to long-term protection of the country Energy security, environmental protection, improving the quality of life of the people, and implementing the scientific development concept.

Building energy conservation has become a major direction and main focus of energy conservation and environmental protection. Under the pressure of severe energy crisis and energy saving, passive building technology has attracted the attention of its green energy saving and environmental protection. Passive houses have already stood at the forefront of the world's energy-efficient buildings. The EU even stipulates that only passive houses will be allowed to be built in the EU from 2020. In China, green buildings have also entered the era of large-scale development. During the “Twelfth Five-Year Plan” period, plans to complete 1 billion square meters of new green buildings; by the end of 2015, 20% of new urban buildings will meet the requirements of green building standards.
