   Looking back to 2022,the construction industry has withstood the test of epidemic situation and other aspects.With the change of the market environment,the transformation of the construction industry is imminent.The construction industry,led by scientific and technological innovation,promotes the transformation and upgrading of the industry to industrialization,green and intelligent.
 
  Fabricated buildings promote production efficiency
 
  In recent years,China has vigorously developed the industrialization of new buildings represented by prefabricated buildings,and promoted the optimization and upgrading of"built in China".A number of independent innovative software have risen,equipment levels have been constantly improved,and a series of world-class construction projects have become the eye-catching signs of"Made in China".The construction industry has developed from the traditional workshop era of on-site mortar mixing and"dusty"to the era of building industrialization of"building houses like cars",and is moving towards the era of digital construction.
 
  Building industrialization makes construction enter factory from construction site and transform from construction to manufacturing.The relevant person in charge of CSCEC Science and Technology Group told the reporter that they have made great efforts to develop the construction industrialization,and started the national layout of manufacturing bases several years ago.At present,they have 24 new construction industrialization manufacturing bases and domestic leading intelligent production lines.
 
  Taking CSCEC Shenzhen Shantou Fabricated Building Intelligent Factory as an example,the factory is equipped with 17 production lines,and has automatic production lines for double skin wallboards,prestressed components,prestressed composite slabs,prestressed double T plates,wallboards,fixed formwork,reinforcement,concrete,etc.It can produce beams,slabs,columns,stairs,balconies and various prestressed components.The design capacity is 220000 m3/year,which can meet the demand for prefabricated buildings of 2 million m3/year.
 
  The intelligent robot for steel bar binding has been used in the intelligent factory of Shenzhen Shantou assembly type buildings.The intelligent robot for steel bar binding can automatically identify and locate the nodes of the steel bar mesh cage.Through the software and hardware such as industrial six axis mechanical arm,tooling fixture,rotary workbench,integrated control system,etc.,the automatic processing of the steel bar mesh cage for the bay window has been realized.The production efficiency has been increased by 4 times,the yield has been increased to more than 95%,and the efficient production,safe production High quality production.
 
  Assembled construction has promoted the energy conservation and emission reduction and production efficiency of the construction industry.Take Beijing Yizhuang Blue Collar Apartment Project as an example.The project is 32 meters high,with a building area of 120,000 square meters,and the overall assembly rate is 92%.Since 90%of the buildings have been manufactured in the factory,the construction site can be free of wet operation,and 70%of water can be saved,so as to achieve zero sewage discharge;No welding and other processes,which can save 70%of electricity;Scaffold free,reducing construction waste by 80%;The building materials can be disassembled and recycled,and the recyclability rate reaches 90%.Six workers on site cooperate with one tower crane to hoist four box houses every hour.If 4 tower cranes work at the same time,88 box houses can be hoisted in one day,the hoisting accuracy can be controlled within 5 mm,and the construction speed is 60%faster than the traditional construction speed.
 
  Recently,the Ministry of Housing and Urban Rural Development released the List of Reproducible and Popularizable Experiences in the Development of Fabricated Buildings(the first batch).Fabricated buildings will seek new breakthroughs in policy guidance,technical support,industrial development,capacity improvement,supervision and management,and innovative development.
 
  At present,more than 20 provinces across the country have introduced support policies and subsidy system standards related to prefabricated buildings,which will help the vigorous development of prefabricated buildings.Industry insiders predict that 80%to 90%of Xiong'an New Area will be prefabricated buildings in the future.The scale of prefabricated buildings of affordable housing in Beijing has reached a high proportion.Fabricated buildings will become the main construction mode in the construction industry in the future,and will also welcome new growth opportunities in the industry.
 
  Accelerate clean and low-carbon transformation
 
  Relevant data show that the energy consumption in the whole process of construction in China accounts for 45%of the total national energy consumption,and the carbon emissions account for 50.6%of the total national emissions.The report of the 20th National Congress of the Communist Party of China proposed to promote clean,low-carbon and efficient use of energy,and promote clean and low-carbon transformation in industries,construction,transportation and other fields.In 2022,the development of green buildings in China will be steadily promoted.
 
  Accelerating the development of green buildings is an important hand in the clean and low-carbon transformation of the construction field.By the first half of 2022,the proportion of new green buildings in China has exceeded 90%.The Fourteenth Five Year Plan for Building Energy Efficiency and Green Building Development proposes that by 2025,new urban buildings will be fully built into green buildings,building energy utilization efficiency will be steadily improved,building energy consumption structure will be gradually optimized,building energy consumption and carbon emission growth trend will be effectively controlled,and a green,low-carbon and circular construction and development mode will be basically formed,laying a solid foundation for carbon peak in urban and rural construction by 2030.
 
  In September 2022,the Ministry of Housing and Urban Rural Development announced the first batch of three-star green building identification projects in 2022.According to the new edition of the Green Building evaluation Standard,the green building evaluation index system in China consists of five categories of indicators:safety and durability,health and comfort,convenient life,resource conservation,and livable environment.Each category of indicators includes control items and scoring items,and is uniformly set with additional items.When all control items in the green building evaluation standards are met,the green building grade shall be basic.When the total score reaches 60 points,70 points and 85 points respectively and meets the technical requirements of the corresponding star level green buildings,the green buildings are rated as one star,two stars and three stars respectively.
 
  It can be seen from the publicity of the first batch of three-star green building identification projects in 2022 that for civil buildings,some key technical indicators must be examined to obtain star green building identification,including the carbon emission intensity in the building operation stage,the thermal performance of the enclosure structure,the proportion of reduction in the heat transfer coefficient of the external windows of residential buildings in cold and cold regions,the water efficiency level of water-saving appliances,the building sound insulation performance,and the concentration of major indoor air pollutants,Air tightness,water tightness and wind pressure resistance of external windows,green space rate of full decoration,total annual runoff control rate,utilization rate of renewable energy,utilization rate of non-traditional water sources,and application ratio of green building materials.
 
  The development of green buildings is inseparable from innovative technical means.At present,the use of advanced technology to make buildings produce more energy than they need for their own operation.Building productive buildings is also an important direction to promote green buildings and building energy conservation.The"light storage,straight and flexible"building is just a productivity building.The State Council's Action Plan for Carbon Peak by 2030 proposes to build a"light storage,direct and flexible"building integrating photovoltaic power generation,energy storage,DC power distribution and flexible power use.
 
  The office building of CSCEC Green Industrial Park in Shenzhen Shantou Special Cooperation Zone is a"light storage,straight and soft"building.This"light storage,direct and flexible"building stores and flexibly uses the electric energy generated by the roof solar photovoltaic power generation device.After more than a year of operation,it has saved more than 100000 kilowatt hours of electricity,saved about 33.34 tons of standard coal,and reduced carbon emissions by more than 47%,which is equivalent to planting trees of 160000 square meters.It has realized the transformation of the building from an energy consumer to a producer,storage and regulator,making the building a"green power plant".Many insiders believe that"light storage,straight and soft"buildings will be a mainstream direction of green buildings and building energy conservation development in the future.
 
  Intelligent Building Helps High Quality Development
 
  At present,intelligent construction has become the inevitable trend of the development of the construction industry and an important hand in the transformation and upgrading of the construction industry.In 2022,intelligent construction will accelerate.In November 2022,the Ministry of Housing and Urban Rural Development will list 24 cities including Beijing,Tianjin,Chongqing and Xiong'an New District of Hebei as pilot cities for intelligent construction,which will last for three years.
 
  Intelligent construction is a project construction method that promotes the construction and construction process to achieve digital design,robot led or auxiliary construction through the cross integration of computer technology,network technology,mechanical and electronic technology,construction technology and management science.It is a leading way to accelerate the transformation and upgrading of the construction industry and realize the modernization of the construction industry.
 
  Ding Lieyun,an academician of the CAE Member,believes that intelligent construction is a new construction mode formed by the integration of information technology and engineering construction.On the basis of digitalization of engineering element resources,comprehensive empowerment is carried out through standardized modeling,networked interaction,visual cognition,high-performance computing and intelligent decision-making.Intelligent construction realizes the integration and efficient collaboration of project planning,planning and design,construction and production,operation and maintenance services driven by the digital chain,and delivers people-oriented,intelligent and green sustainable engineering products and services.Intelligent construction promotes the interconnection of engineering construction process,the integration of online and offline,and the coordination of resources and elements,which is an important support for achieving high-quality development of the construction industry.
 
  At the construction site of Beijing Anzhen Hospital in Tongzhou District,Songzhuang Town,Tongzhou District,Beijing,construction is under way.According to Xiong Zhengchao,the chief engineer of Tongzhou Hospital District Project of Beijing Anzhen Hospital of Beijing Urban Construction Group,medical engineering is highly professional,demanding,large in structure,difficult in organization and material management,numerous in electromechanical specialties,and difficult in pipeline layout.Relying on high standard digital construction and promoting intelligent construction,high-quality construction is ensured.
 
  Xiong Zhengchao introduced that by building a virtual construction information model,most of the construction processes can be simulated when the project starts,or many unforeseen practices can be optimized through digital modeling.The construction personnel can really intervene before each process starts,abandoning the traditional way of solving problems in the form of"see the bidding"and"feel the stone to cross the river".Through digital empowerment and analog construction,we can get twice the result with half the effort.At the same time,the digital management platform is introduced to upload various information during the construction process to the management platform in time,so that project decision-makers can understand the project dynamics without leaving home,and can quickly find problems,make decisions and allocate resources.
 
  Xiong Zhengchao said that by using advanced technologies such as 5G,big data,AI artificial intelligence and AR augmented reality,they have built a comprehensive management platform of"5G smart construction site",allowing the mobile Internet,the Internet of Things,big data,etc.to be deeply integrated with the construction site,which not only improves the efficiency of project management,ensures the smooth implementation of the project,but also reduces the cost of construction site management,and actively realizes green construction,ecological construction and smart construction.
 
  According to the relevant person in charge of the Ministry of Housing and Urban Rural Development,24 cities have been listed as pilot cities for intelligent construction.The main direction is to promote the deep integration of the construction industry and the digital economy,foster new industries,new forms and new models for intelligent construction,and strive to solve the problems of extensive production methods,labor shortage,large resource and energy consumption and other outstanding problems in engineering construction,Give better play to the important supporting role of the construction industry in stabilizing growth and expanding domestic demand.
 
  The development of intelligent construction is of great significance and great potential.By promoting the coordinated development of intelligent construction and building industrialization,the core competitiveness of"Made in China"will continue to improve,and the high-quality development achievements of the construction industry will also be more eye-catching.
