With the increasing call for global green and low-carbon transformation and sustainable development, prefabricated buildings, as an emerging
In 2023, the completed area of green buildings in the entire state has reached 2.702 million square meters, accounting for 99.78% of the completed area of new urban buildings; The buildings constructed using prefabricated technology system cover an area of 1.1925 million square meters, accounting for 28.1% of the newly started urban construction area..
Strictly implementing policies is a prerequisite. The entire state’s housing and construction system conscientiously implements the Ministry of Housing and Urban Rural Development and the Yunnan Provincial Department of Housing and Urban Rural Development’s “14th Five Year Plan” for building energy conservation and green building development, as well as the implementation plan for carbon peak in urban and rural construction. It clarifies the development goals and policy requirements of green prefabricated buildings, and tightens and compacts work responsibilities..
Strengthening project review is crucial. According to the relevant regulations of the Yunnan Provincial Department of Housing and Urban Rural Development on further strengthening the full process management of building energy conservation and green buildings, the focus is on implementing green prefabricated buildings with government investment in public welfare buildings, large public buildings, affordable housing, industrial factories, etc. During the project design stage, the review and filing system is strictly implemented to ensure that new urban buildings fully comply with green building standards..
Promoting building energy efficiency is the key. Strictly implementing mandatory standards for building energy efficiency drives the development of green prefabricated buildings, ensuring that new urban buildings fully comply with building energy efficiency standards. By combining the renovation of old urban residential areas, the renovation of dangerous old buildings, and seismic reinforcement, we will comprehensively promote the energy-saving renovation of existing buildings, continuously improve the energy efficiency level of existing buildings. For newly built buildings that meet the conditions for solar energy utilization, solar energy systems will be mandatory to be installed during the design stage, reducing building energy consumption and promoting the development of green prefabricated buildings..
The construction of industrial bases is the foundation. By taking measures such as providing on-site services and providing guidance and assistance, we support leading enterprises in the field of new building materials to apply for Yunnan Province’s green prefabricated building industry base and enjoy financial rewards and subsidies, and promote the construction of prefabricated building industry bases. At present, Chuxiong City has formed an industrial base with aerated concrete construction as the main product line, and Lufeng City has an industrial base with steel structure as the main product. One enterprise has been evaluated by the Yunnan Provincial Department of Housing and Urban Rural Development as a green prefabricated building industrial base in Yunnan Province. The number of manufacturing enterprises and product category coverage of prefabricated building components are gradually expanding, effectively solving the basic building materials problem in the development process of green prefabricated buildings. The construction project has saved time and procurement costs in the procurement process of basic building materials, providing a foundation for accelerating the promotion of green prefabricated buildings throughout the province..
Adequate supply of building materials is a guarantee. The production capacity of concrete blocks and wall panels produced by enterprises in the state has reached 500000 cubic meters per year, and the products have been evaluated and issued a green building material evaluation label product certificate by China Academy of Building Science Co., Ltd; The steel structure components produced in the Tuguan area of Lufeng Industrial Park are widely used in civil construction, industrial factories, roads and bridges, and other industries. Currently, two building materials products (concrete slabs and aerated concrete blocks) in the state have been rated as three-star green building materials. The sufficient supply of green prefabricated building materials provides the most solid support for the vigorous development of green prefabricated buildings.
