It is suggested that through the national science and technology plan, the research on steel manufacturing, building energy-saving materials and building standard system should be organized intensively, so as to form a steel structure building standard system and production specifications suitable for China’s national conditions as soon as possible, form an industrial chain and implement them nationwide.

If the affordable housing is required to be constructed with steel structure; When auctioning commercial housing land, it is required to build 10% – 15% steel structure houses; When approving a construction project, the tax rate shall be determined according to the carbon emission of the building; Reduce the steel structure processing tax rate to 9%.

The steel structure residence is delivered in the set area.

Vigorously promote the digital construction with steel structure as the main body.

China real estate news reporter learned that he Wenbo, member of the CPPCC National Committee and Secretary of the Party committee and executive chairman of China Iron and Steel Industry Association, submitted the proposal on vigorously promoting the construction of precast steel structure housing.

Background: China has promised the international community the “double carbon” goal of carbon peak in 2030 and carbon neutralization in 2060.

Increase incentives for the development of green buildings..

Build an Internet collaboration platform for steel construction industry.

How to achieve the goal of “double carbon” in cities, green and low-carbon buildings are one of them.

He Wenbo said: “the wide use of steel structure, especially the development of precast steel structure housing, will play a great role in realizing the industrialization of the construction industry and promoting intelligent construction.

The development of steel structure buildings is not only the direction of transformation and upgrading of the construction industry, but also the power source of product structure optimization and high-quality development of the iron and steel industry, but also an effective way of strategic reserve of iron and steel resources.

Adjust policies such as taxes and fees.

Steel structure buildings have green and low-carbon characteristics.

5.

Comprehensively promote the construction of demonstration projects.

However, at present, the proportion of steel structure buildings in the total construction volume in developed countries is more than 40%, that in China is only 5% – 7%, and that of steel structure houses is only about 1%.

Cancel civil air defense works in steel structure buildings or reduce the cost of relocation construction.

In view of the insufficient understanding of the importance of developing steel structure buildings in the whole society and the insufficient coordination between iron and steel enterprises and the whole industrial chain of steel structure R & D, design, manufacturing and engineering, resulting in the high construction cost, low application rate of steel and limited supply mode of steel structure buildings, he Wenbo suggested: first, improve relevant policies and continuously optimize the development environment.

In view of the fact that the construction of civil air defense project will reduce the construction progress of steel structure residence, it is suggested that the management department cancel the civil air defense project in steel structure buildings or appropriately reduce the relocation construction cost of civil air defense project.

Cultivate a number of leading enterprises integrating design, construction and production, vigorously promote the general contracting of precast construction projects, and integrate the services required in the process of project construction, such as preliminary consultation, bidding agency, survey and design, cost consultation, project supervision and so on.

Green low-carbon buildings should not only reduce carbon emissions in the construction process, but also significantly reduce the daily energy consumption and emissions of buildings.

Compared with concrete buildings, steel structure buildings can reduce 12% energy consumption, 39% water consumption, 15% carbon dioxide emission, 6% nitrogen oxide emission, 32% sulfur dioxide emission, 59% dust emission and 51% solid waste during production and construction; Through intelligent construction, the comprehensive cost of buildings can be reduced by more than 20%; At the end of the service life of steel structure buildings, steel can be recycled, and the effect of energy conservation, emission reduction and efficient utilization of resources is very considerable.

Government and private investment projects are encouraged to implement general contracting and whole process consulting services.

Increase support for assembly technology and encourage real estate and construction enterprises to take the road of EPC and assembly.

In view of the fact that the concrete will be destroyed when the temperature is higher than 400 ℃ in the building fire prevention materials, and the steel structure can not melt until the high temperature of 800 ℃ – 1000 ℃, it is suggested to adjust the building fire prevention code and adopt the steel structure fire prevention code.

On March 4, Chen Jinshi, deputy to the National People’s Congress and chairman of the board of directors of Zhongnan group, put forward four suggestions on precast buildings, which are as follows: it is suggested to focus on the national double carbon strategy, optimize the relevant standards of green buildings, vigorously promote the technological innovation of precast buildings, and encourage real estate and construction enterprises to take the road of EPC and assembly.

Promote the construction of pilot demonstration projects and supporting policies.

Build an Internet collaborative platform for the steel construction industry, form a new production mode of the construction industry and reduce the overall cost through the customization of construction products and the industrialization of construction production.

In view of the high strength of steel structure building materials, small component volume and high proportion of usable area, it is suggested that the government introduce the policy of delivery of steel structure residential area, so as to fully reflect the advantages of steel structure building.

On March 4, 2022, the fifth session of the 13th CPPCC National Committee opened in Beijing.

In this process, steel materials will give full play to their characteristics of high efficiency, recycling and green.

2、 Take standardization and intellectualization as the starting point, improve the intelligent construction system with precast steel structure as the main body.

For pilot projects, scientific research projects and industrialization projects of steel structure housing, necessary support and preference shall be given in terms of taxes, funds and project approval.

Carry out research on standard system, material system and construction system of steel structure housing.

The seamless connection and green interaction between the steel industry and the construction industry have great potential and unlimited prospects for realizing the goal of” double carbon “.

2.

Under the guidance of the national science and technology plan, strengthen collaborative innovation and realize the digital construction of the whole life cycle of buildings through the digital product model of the whole life cycle of buildings.

While encouraging the use of precast steel structure buildings in resettlement houses, introduce supporting policies such as pre-sale of precast steel structure buildings in advance, cancellation of partition walls and step-by-step and itemized acceptance.

Seven departments including the national development and Reform Commission issued the implementation plan for promoting green consumption in January this year, which clearly requires to promote the large-scale development of green and low-carbon buildings.

Adjust the building fire prevention code.

Specific suggestions: 1.

Continuously optimize the architectural design code of precast steel structure.
