During the "13th Five-Year Plan" period, the prefabricated buildings nationwide reached 1.6 billion square meters

A few days ago, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council issued the "Opinions on Promoting the Green Development of Urban and Rural Construction" (hereinafter referred to as the "Opinions"). The "Opinions" mentioned that it is required to carry out the creation of green construction demonstration projects, promote green, industrialization, informatization, intensification and industrialization of construction methods, use new technologies to achieve refined design and construction, and vigorously develop prefabricated buildings. Improve the certification system for green building materials products, strengthen the recycling of building materials, promote the transformation and upgrading of the traditional construction industry, reform the construction labor and employment system, and accelerate the reform of project costs.

At a press conference held by the State Council Information Office on October 25, Tian Guomin, director of the Standards and Quota Department of the Ministry of Housing and Urban-Rural Development, said that the construction sector has high resource consumption, high emissions, and extensive construction methods. The problems are still more prominent. It is imminent to promote green construction and promote the transformation and upgrading of the development mode of the construction industry.

To this end, in practice, the Ministry of Housing and Urban-Rural Development has promoted three regions of Hunan Province, Shenzhen City in Guangdong Province, and Changzhou City in Jiangsu Province to carry out green construction pilot projects, and has issued the "Technical Guidelines for Green Construction (Trial)". At the same time, promote the rapid development of prefabricated buildings. During the "13th Five-Year Plan" period, a total of 1.6 billion square meters of prefabricated buildings have been built, with an average annual growth rate of 54%. Among them, newly started prefabricated buildings accounted for 20.5% of new buildings in 2021.

In addition, the Ministry of Housing and Urban-Rural Development focuses on promoting the pilot construction of steel structure residential buildings. According to Tian Guomin, in 2020, 190 million square meters of steel structure buildings will be newly started nationwide, an increase of 46% compared to 2019, accounting for 30.2% of newly started prefabricated buildings. Among them, about 12 million square meters of steel structure residential buildings were newly started, an increase of 33% from 2019.

Tian Guomin said that in the next step, in order to promote the development of prefabricated buildings and steel structure buildings, the Ministry of Housing and Urban-Rural Development will build a standardized design and production system and compile the "Design Selection Standards for Prefabricated Houses." Promote the positive design method of "less specifications, more combinations", expand the scale of standardized production and use, and promote the marketization and large-scale development of prefabricated buildings. Continuously improve the prefabricated concrete building structure system suitable for different building types, and accelerate the opening up of the industrial chain of steel structure residential design, production, and construction. Increase promotion efforts, instruct local governments to actively apply prefabricated concrete structures in affordable housing and commercial housing, actively carry out pilot projects for steel structure housing, and encourage hospitals, schools and other public buildings to preferentially use steel structures.
