1. Chengdu: Fine management cultivates the "trillion -level industrial cluster"

【Industrial Chain Business Card】

During the "Thirteenth Five -Year Plan" period, Chengdu vigorously promoted green buildings in the city. Green buildings comprehensively covered the city's new construction land projects. The total area exceeded 200 million square meters, and the Green Film area of ​​Tianfu International Airport, Shinchuan Green Ecological City, etc. For large -scale application results, 245 projects have been evaluated by green buildings.

This year, the city clearly stated that by 2025, prefabricated buildings accounted for 80%of the newly built buildings in the town that year, and the proportion of green building materials should not be less than 60%. The trillion -level green construction industry cluster composed of the industry.

In recent years, "prefabricated buildings" have been a hot word. This new construction method is more economical, green, wisdom, and aesthetic. It is the transformation of construction methods and the general trend of the development of the construction industry.

Chengdu is not only the country's first batch of prefabricated buildings demonstration cities, but also a pilot city for Sichuan Province to vigorously develop prefabricated buildings.

Since 2016, Chengdu's global housing construction and municipal engineering projects have been comprehensively promoted to prefabricated buildings. Since 2019, the city has clearly suggested that the construction of the construction of the self -housing project has been increased to no less than 30%; the government -invested housing, talent apartments, schools, hospitals, office buildings, parking buildings projects have increased to not less than 50% Essence From the perspective of the cultivation of the industrial chain, Chengdu's prefabricated building industry has developed steadily, and 43 assembly building production bases are built (under construction), including 9 national demonstration bases and 8 provincial demonstration bases, which have formed a strong formation, which has formed a strong. The entire industry chain.

The reason why Chengdu's prefabricated buildings have become "national pacesetters" than refined management. In 2020, the city's requirements in accordance with the "Implementation Opinions of the General Office of the People's Government of Chengdu on vigorously promoting the high -quality development of green buildings to help the construction of high -quality life and livable land" have put forward specific requirements for further improving the prefabricated construction projects in Chengdu.

In terms of implementation standards, the city put forward specific requirements for housing construction projects, municipal infrastructure, and rail transit construction projects. Among them, all the housing construction projects implement the requirements for prefabricated buildings, and the average or average assembly rate is not less than 40%. Among them, government investment projects, a residential building project with a total construction area of ​​more than 200,000 square meters, and the building area of ​​the residential building part of 20 20,000 square meters. The uniform or average assembly rate of more than 10,000 square meters is not less than 50%. All districts (cities) and counties actively promote the construction of A-level-AAA-level prefabricated buildings.

Refined management runs through the entire process of the entire prefabricated building. For example, the city is clear when adjusting the corresponding standards: During the land transfer stage, the competent departments of housing urban and rural construction at all levels shall clarify the construction requirements of prefabricated building construction in the construction conditions; in the design stage, the design unit shall prepare assembly building design design Special articles, the construction map review agency shall implement special review; during the construction stage, the competent department of housing and urban and rural construction at all levels shall strictly implement the relevant requirements of the quality management of prefabricated construction projects, strengthen the management of design change management and completion acceptance management, and ensure that the prefabricated construction requirements are required to land on the ground. implement.

From planning to execution, from comprehensive to focus, refined management allows each part of each part of the construction of green buildings, green building -related manufacturing, and green building -related services. The city is full of confidence that by 2025, a trillion -level green building industry cluster will be created. Among them, the total output value of green building construction will strive to exceed 800 billion yuan, and the operating income of green buildings related manufacturing and green building -related service industries will reach 2000 respectively. More than 100 million yuan.

2. Shenzhen: Innovate the Green Architecture World Stage in Innovation

【Industrial Chain Business Card】

In recent years, Shenzhen has accelerated the high -quality development of environmental protection and energy -saving and prefabricated buildings. The highest and best benchmarking and the strongest and strongest benchmarking, comprehensively driving the construction industry's industry chain to green, industrialization, intelligence, and internationalization. During the "Thirteenth Five -Year Plan" period, the city incubated and cultivated the national prefabricated construction industrial bases, 29 provincial -level bases and 31 municipal base bases such as Vanke Group, including Vanke Group. Living second, it becomes a sample of high -quality development in the country.

Shenzhen quickly built from a border agricultural county into a charming and vibrant international innovative city, and the construction industry made great contributions. In order to further improve the level of construction technology and construction efficiency, improve the quality and safety of housing building, and promote energy conservation and emission reduction, the city has taken the lead in the only way for the transformation and upgrading of the traditional construction industry -vigorously developing environmental protection and energy -saving and assembly buildings.

As early as 2006, Shenzhen became the first comprehensive pilot city in the country's industrialization. Vanke and Huayang International were early prefabricated construction industrial bases. The development of prefabricated buildings in the city has always led the development of national prefabricated buildings.

Because dare to innovate first and courage to innovate, Shenzhen's green construction industry is always in a "one riding dust" position. The first national prefabricated architectural titles, the first construction series of industrial workers' training bases, the first prefabricated building group standard, the first prefabricated concrete component production enterprise "Registration Management+Star Evaluation" industry self -discipline management system ... as of 2020 , Shenzhen has introduced 15 policy documents and 13 standards related to equipped construction; a number of "Luban Awards" and national standard 3A boutique projects have been created by the Shenzhen Campus of Harbin Institute of Technology and the Hanjing Center; Provincial and municipal industrial bases; created the first nationwide prefabricated construction professional titles; and the first 7 -style construction training bases in the province were completed.

Innovative factors are active in all aspects of the construction industry. Shenzhen will in -depth integration of prefabricated buildings and green buildings, energy -saving buildings, and smart buildings, increase technical research and innovative development investment, build a technical support system suitable for local development, promote the integration of prefabricated buildings and informatization, and use prefabricated buildings with prefabricated buildings Improve the development level of green buildings. For example, explore the country's first urban -level energy consumption management system, use modern information technology to monitor the power consumption, cold (heat) consumption, and the power consumption is divided into lighting sockets, air conditioning, power and special, etc. Monitor the four major points, transmit the various energy consumption data collected to the data center through the network, and use the energy consumption monitoring platform to process, analyze and display the energy consumption data of the building classification, and effectively control the quality, investment, and progress of the project. Improve the quality of architecture.

Today, the "Shenzhen Experience" leading green buildings is replicated and promoted in the Guangdong -Hong Kong -Macao Greater Bay Area and even the country. A number of local companies have stepped out of Shenzhen, nationwide, and even competitive world stage: Vanke Group's prefabricated buildings in 65 major cities across the country The accumulated area exceeded 200 million square meters, ranking first in the country; the annual production capacity of the steel structure of China Construction Science and Technology ranks first in the country, and the projects are all over the world. More than 100 hotels and apartment construction projects have been completed abroad; the overall bathroom of South China building materials has traveled throughout the world with ocean ships.

3. Shanghai: "True Gold and Silver" promote the standardization of industrial standardization

【Industrial Business Card】

In the country, Shanghai is one of the earliest cities to develop prefabricated buildings. Its prefabricated buildings account for 86.4%of the proportion of new buildings. As of July 2020, a total of more than 120 million square meters was implemented during the land transfer stage of Shanghai. At present, the city's total output value of the construction industry is 923.642 billion yuan, an increase of 11.6%over the previous year.

Looking back at the promotion of Shanghai prefabricated buildings, it has gone through three stages: the pilot exploration period before 2010, with the support of the "Shanghai Residential Industry Modernization Pilot Work Plan" and other policies, the work framework for the industrialization of local residential industrialization was initially formed; 2011 As of the pilot advancement period in 2013, through the means of administrative supervision and market incentives, it has made breakthroughs in technological accumulation, and the level of residential industrialization has steadily improved; the comprehensive promotion period from 2014 to the present has been expanded from residential buildings to public buildings. The number of projects using prefabricated construction has doubled.

After the exploration and development of the above three stages, in the process of vigorously promoting the development of prefabricated buildings, Shanghai has always advocated the dominant role of the market in the allocation of resources. With a real project plan to release market demand, it greatly revitalizes the market and promotes the promotion The prosperity and development of the industrial chain.

Standardization has always been a proposition around prefabricated buildings. At present, the standardization of prefabricated building products is low. Each developer and each building are designed differently. Most of the products are customized, and customization means high price.

Regarding the standardization of prefabricated building components, Shanghai has also made efforts in the construction of the general standard system. It has initially established a standard specification system from prefabricated building design, construction installation, and component production to completion acceptance. Prior to June 2015, standards and atlas were published in the "Design Regulations for the Design of Establishment of Portal Concrete Housing System" and "Preparation of Overall Residential Concrete Components, Construction and Quality Acceptance Regulations", which basically met the needs of the development of informal construction at the time. The "Prefabricated Building Evaluation Standard", which was implemented on April 1, 2020, evaluated the prefabricated buildings from a full cycle to further guide the positive design concept, and promoted the improvement of construction efficiency and reasonable control of construction costs. In order to improve the enthusiasm of building green buildings, on the basis of adhering to policy guidance, Shanghai has introduced policies such as special funds for demonstration projects, pre -sale preferential commercial housing preparations, and award for plot ratio. The enthusiasm of the development enterprise is enthusiastic.

In 2014, Shanghai established the "Shanghai Green Building Development Joint Meeting" consisting of more than 20 committees (office, bureau), including planning natural resources, development and reform, housing urban and rural construction, and finance. Work landing. At the same time, with the source control of the land as the starting point, the prefabricated construction construction requirements are written into the land transfer contract to fully ensure the smooth landing of prefabricated projects. In addition, prefabricated construction engineering projects can be submitted and staged in stages, and new prefabricated commercial residential projects can be pre -sale in advance when reaching a certain project progress. Compared with the pre -sale policy of traditional construction methods, this move greatly reduces the financial and time costs of prefabricated construction development enterprises, and plays a better market incentive.

In addition to policy dividends, there are real real gold and silver. The city has continuously introduced policies such as planning and rewards, fund subsidies, and wall materials special funds for prefabricated construction projects. For example, a prefabricated building demonstration project with an evaluation level reaches the AA subsidy of 60 yuan per square meter to reach 100 yuan per square meter of AAA; the prefabricated sandwich insulation wall is used for prefabricated building exterior walls. Reward.

4. Hangzhou: Talent support to build a modern "strong building"

【Industrial Chain Business Card】

Hangzhou is the first batch of "national prefabricated building demonstration cities" in the country. Since 2017, most of the houses in Hangzhou's main urban area have required 100%to implement prefabricated buildings. According to data from the Hangzhou Municipal Construction Commission, during the "Thirteenth Five -Year Plan" period, Hangzhou's newly -started assembly buildings accounted for 31%of new buildings. At present, the city has basically formed an industrialized industry chain integrating development, design, production, and construction. In 2021, the total output value of the city's construction industry was 557.457 billion yuan, an increase of 13.2%year -on -year, and the total output value ranked first in the province.

The construction industry is Hangzhou's traditional pillar industry and rich people. In recent years, Hangzhou has continuously innovated the policy of reducing the burden of enterprises and optimizing the business environment, has effectively promoted the continuous transformation and upgrading of the construction industry, and achieved the effective improvement of the industrial scale and quality.

Earlier this year, Hangzhou issued and implemented the "Implementation Opinions on Promoting the High -quality Development of the Construction Industry in Our City" (hereinafter referred to as "Opinions"). Digitalization and intelligence levels have accelerated construction methods to green low -carbon transformation.

Any advanced technology and perfect standards depends on talent support. From design, production to construction assembly, prefabricated buildings have fundamentally changed the traditional construction method. The cultivation of new talent teams is the top priority of industry development. The "Opinions" mentioned that it will further strengthen talent support and accelerate Hangzhou from the "construction industry" to "strong construction industry".

For a long time, Hangzhou has attached great importance to talent training, established a prefabricated industrial worker training base, compiled and published the assessment standards for prefabricated series of occupational professional level, publishing series of training materials, and organizing and conducting various occupational level evaluations. And practice.

Hangzhou takes the starting point and foothold for "building knowledge type, skill type, innovative construction industry workers, promoting the spirit of model workers and craftsmanship", and organizes the construction of high -skilled talents in the industry every year. "Bridge" has also effectively promoted the cultivation of the Hangzhou construction industry workers.

It is worth mentioning that the city played the role of government guidance, college support and enterprise subjects, further deepening political, school, and enterprise cooperation, establishing the modern industrial branch of Zhejiang Construction Industry Branch, and the integration of construction decoration and education 2. School -enterprise cooperation, explore the establishment of the construction industry's modern industrial chain, skill chain, and educational chain organic connection, and achieve organic combination of skill training, practical training and on -site construction to comprehensively improve the professional skills and comprehensive quality of the construction industry workers.

Among them, the Hangzhou Architectural Decoration Industry and Education Integration Alliance was jointly initiated by Yaxia Group and Hangzhou Vocational Education and Adult Education Research Office. Middle school and Zhejiang Yaxia Decoration Co., Ltd. are composed of together. Yaxia Group is a leading enterprise in the national building decoration industry and the first national high -tech enterprise. With "industrialization", it has invested more than 1 billion yuan to focus on research and development of all -industrial chain of prefabricated interior.

The alliance is guided by industrial transformation and upgrading, based on the industrial chain and innovation chain, reconstructing the talent chain and education chain, and systematically designed the overall solution of the integration of production and education. According to the Alliance Agreement, Yaxia Group will jointly build Hangzhou Construction Vocational School and Hangzhou West Lake Vocational Senior High School. The center and training center, train the talent team that matches the innovation chain and the industrial chain. In addition, Hangzhou also organizes to carry out professional skills competitions for construction industry, do a good job of "the most beautiful builder" and "construction craftsman" and other tree selection work. Through job training, skill competition, etc. Degree and communication. At present, the vocational training system of industrial workers in Hangzhou has been gradually established, and the nation's first light steel structure assembly residential industry worker training base has been established in the country.

▲ Guoxin Great Building -Automatic Production Line

Under the influence of multiple favorable policies, green buildings, especially prefabricated buildings, have broad development space, and are standing on the opportunity. Between various places, the "new track" of the new industry is grabbing the beach.

From the perspective of every people and residents, green buildings can provide us with a more comfortable life, work and recreational environment, improve the quality of life, and reduce the cost of life. From the perspective of the economic and social development of a city, advancing environmental protection and energy -saving and equipment -type buildings is the requirements for supply -side structural reforms in this industry. Cultivate modern construction industry clusters, and can promote the main measures for the conversion and transformation and upgrading of new and old kinetic energy in the construction industry. It can be seen that the promotion and application of this new industry has driven green investment and consumption, which is the responsibility and responsibility.

Although Zhuzhou's prefabricated industries have started late, the momentum is very fierce. In just two years, it has jumped from the province to become the "first in the province." But looking at the whole country, compared with developed cities, we still have a certain gap. Not only do we have problems such as low coverage and unbalanced regional development, but also facing challenges with high economic downlink pressure, incomplete industrial chain, fewer related enterprises, fewer related enterprises. The lack of relevant talents is equal, which in turn affects the market applications and promotion of green buildings.

From the perspective of successful experience in various places, they are cultivated through the government's "tangible hands" and the market "invisible hands" to make them bigger and stronger. In terms of policies, the city introduced the "Zhuzhou City Prefabricated Building Industry Development Plan (2019-2025)". It is clear that starting from 2020, prefabricated buildings account for not less than 50%of the new buildings. At the same time Strengthening fiscal support, ensuring land supply, implementation of plot ratio rewards, and implementation of taxes and fees are given strong support for industrial development. Therefore, on the one hand, we must put the policy into the implementation, let the relevant companies enjoy the "policy dividend", and use this to attract and compete for more good projects and large projects, and continue to make up for the front end, the strong main chain, and extend the back end. Form a complete and powerful industrial chain; on the other hand, based on market demand to deepen production, learning, and research, especially to promote the integration of policy chain, industrial chain, innovation chain, capital chain, and talent chain Improve the level of industrialization, digitalization, and intelligence in the industry, and help the upgrade of the prefabricated construction industry.

The development of energy conservation and emission reduction and prefabricated construction industry chain is a challenge, the same opportunity, and potential. We are happy to see this industry continuously improved and accelerated, and decorating Zhuzhou land more colorful.
