Ningbo, Zhejiang, Guangzhou, Guangdong, Chengdu, Sichuan and other places have successively issued implementation plans to orderly promote the upgrading of facilities and equipment in the fields of construction and building energy conservation, and accelerate the industrialization, intelligence and greening process of the construction industry.

Updating Construction Equipment - Promoting Industrial Development

The renovation of construction equipment in the field of construction has a large investment volume and strong driving ability, which is an important focus for expanding domestic demand, benefiting people's livelihoods, and stabilizing growth. It is of great significance for promoting high-quality urban development.

Ningbo, Zhejiang Province requires strengthening engineering construction supervision services to promote the renewal of market entities as the main focus, with the goal of improving safety and quality levels and enhancing production efficiency, and orderly promoting the renewal of facilities and equipment in the construction field.

On the one hand, conduct a comprehensive survey to dynamically grasp the demand and current situation of facility and equipment updates. Establish an organizational framework for the linkage between the city and county levels, and conduct comprehensive surveys and research on industry chain market entities such as construction general contracting enterprises, professional contracting enterprises, local building materials enterprises, PC component factories, steel structure factories, and equipment leasing enterprises. Develop a classification list of facilities and equipment for construction and local building materials enterprises, establish a facility and equipment data information database, and dynamically grasp the needs and current status of facility and equipment updates.

On the other hand, we will coordinate with the Ministry of Economy and Information Technology to establish a list of manufacturers of construction machinery and equipment. Through equipment exhibitions, product supply lists, and other forms, we will promote high-quality, low-priced, and excellent after-sales products and equipment to enterprises, promoting mutual development between the construction industry and equipment manufacturing industry. At the same time, we will increase our negotiation efforts with financial institutions to obtain low interest loans, green finance and other financial tools for enterprises, and strengthen the funding guarantee for equipment updates.

Equipment updates are a major opportunity to promote industrial upgrading. The Ningbo Housing and Urban Rural Development Bureau takes the update of facilities and equipment as an opportunity to promote the transformation of construction enterprises towards the intelligent construction "track", encourage the optimization and integration of industries such as building materials, construction machinery, construction equipment, technology research and development, and construction, and create emerging industrial clusters such as "construction services+green building materials", "construction services+component production", "construction services+equipment research and development", and "construction services+digital platforms".

Guangzhou, Guangdong plans to complete the renovation and renovation of construction equipment that has a long service life, outdated technology, does not meet relevant standards and regulations, does not meet energy-saving and environmental protection standards, and has safety hazards by 2027 according to the plan.

It is reported that Guangzhou encourages enterprises to actively participate in the updating of construction equipment, and includes medium-sized or construction equipment worth more than 50000 yuan in the ledger management. Support leading backbone construction enterprises to actively update construction equipment, and lead the construction industry to create an atmosphere that encourages advanced and eliminates backward. When subcontracting construction projects undertaken by state-owned enterprises in accordance with the law, it is encouraged to stipulate in the contract that professional contracting units and equipment leasing units should update and use construction equipment that meets the requirements. At the same time, it is proposed to support enterprises to carry out renovation work through financial leasing, and require the housing and urban-rural development bureaus of all districts to actively coordinate and connect the supply and demand information of the upstream and downstream of the construction equipment supply chain, form a price advantage of quantity based procurement, and support enterprises to widely carry out construction equipment renovation through financial leasing, financing leasing and other methods.

Guangzhou has also put forward requirements for government investment construction projects. For government investment (including state-owned enterprise investment) construction projects of a certain scale (with an investment scale of 100 million yuan or more), the construction unit can use advanced construction equipment (including intelligent construction equipment) as evaluation factors in the project bidding. The winning bidder is required to promise not to use equipment that does not meet energy-saving and environmental protection standards, or has safety hazards. Clearly specify the requirements for the entry and use of construction equipment on the construction site in construction contracts and other documents. The construction unit may include the use of construction equipment on the construction site in the post bid performance management, urge the general contracting unit to increase safety investment, update the main construction equipment related to structural quality and safety on the construction site according to regulations, apply advanced intelligent construction equipment, gradually eliminate outdated construction equipment, and improve the level of construction safety protection.

In addition, enterprises are encouraged to promote the application of advanced technology and highly digitized, intelligent, and industrialized construction equipment, such as building machines, 5G tower cranes, intelligent elevators, construction robots, etc., to guide high-quality upstream and downstream enterprises to form an advanced construction industry chain and promote the transformation and upgrading of traditional construction industry to new construction industrialization. Support enterprises to focus on technological innovation, develop intelligent, industrialized, and green new construction methods, create a number of intelligent construction pilot benchmark projects, develop new quality productivity in the construction industry, and vigorously promote the application of new energy and new technologies in construction equipment.

Building Energy Efficiency Renovation and Renewal - Improving Residential Quality

The energy-saving renovation of existing buildings is one of the key tasks to improve the energy efficiency level of existing buildings and accelerate energy conservation and carbon reduction in the construction industry. It is also an important means to accelerate the filling of gaps, upgrading and upgrading of industry facilities and equipment, improve quality and efficiency, enhance the overall level of facilities and equipment, and meet the high-quality living needs of the people.

Chengdu, Sichuan Province plans to add 2.65 million square meters of building energy-saving renovation area by the end of 2027, improve the system, mechanism and policy system of building energy-saving renovation, and build a number of high-quality building energy-saving renovation pilot projects. Key renovation of public buildings that have been completed for more than 10 years within the urban area and residential buildings that have not taken energy-saving measures (mainly multi story residential buildings completed before 2005), updating and renovating heat pump units, radiators, chillers, external windows (curtain walls), external walls (roofs) insulation, lighting equipment, etc. that exceed their service life, have low energy efficiency, pose safety hazards, and have no maintenance value.

In terms of renovation methods, Chengdu city requires that the exterior windows of residential buildings can be renovated on a household basis, and the color, specifications, and exterior facade should be uniformly coordinated after renovation. External wall insulation, roof insulation, sunshades, etc. are implemented on a building by building basis in accordance with relevant regulations for energy-saving renovation of existing buildings. The community committee, property management committee, and property service personnel can organize the renovation in accordance with relevant regulations to ensure coordination with the surrounding environment and ensure the safety of the building. The energy-saving renovation of buildings must ensure the overall integrity, seismic resistance, and structural safety of the building, and comply with the technical specifications for fire protection in engineering construction. It must not infringe on facilities in public areas, occupy public spaces, or affect the original style and characteristics of the renovation area.

Shanxi Province requires all cities to conduct a survey of existing buildings in urban areas, establish a database for energy-saving renovation of buildings, and establish a project reserve database. Combining the renovation of old residential areas and clean heating work, we will coordinate the promotion of energy-saving renovation of existing residential buildings.

In the energy-saving renovation of existing buildings, efforts should be made to promote the updating and renovation of building equipment. In accordance with policies such as the "Advanced Energy Efficiency Level, Energy Efficiency Level, and Access Level of Key Energy consuming Product Equipment (2024 Edition)" and the "General Specification for Building Energy Conservation and Renewable Energy", as well as current national and industry standards, the focus should be on updating heat pump units, radiators, chillers, exterior windows (curtain walls), exterior wall (roof) insulation, lighting and other equipment that do not meet current product standards, exceed equipment service life, have safety hazards and no maintenance value, have low energy efficiency, have experienced major accidents, and have suffered serious damage to major components.

Chongqing proposes to actively coordinate with energy-saving service companies and renovation project owners to strengthen work coordination, promote green and low-carbon renovation of existing public buildings, guide relevant units to carry out energy-saving and green renovation of key energy consuming equipment and facilities such as exterior envelope structures, doors and windows, electrical lighting, HVAC, etc. in accordance with the overall energy efficiency improvement and other renovation goals. The addition or renovation of solar energy systems in existing buildings must undergo structural and electrical safety reviews to meet safety requirements such as structure, fire prevention, and lightning protection, and must not compromise safety, energy efficiency, and other performance.
