A few days ago, the Ministry of Housing and Urban-Rural Development issued the "Notice on Promoting the Implementation Plan for the Renewal of Construction and Municipal Infrastructure Equipment".
The plan requires that residential elevators, water supply, heating, gas supply, sewage treatment, sanitation, urban lifeline projects, building energy-saving renovation and other key points will be used to promote the renewal of building and municipal infrastructure equipment by category.
Efforts will be made to expand domestic demand, benefit people's livelihood, ensure safety, ensure the safe, green and intelligent operation of urban infrastructure, and promote high-quality urban development.
By 2027, the equipment with backward technology, not meeting the relevant standards and specifications, and not meeting the standards of energy conservation and environmental protection will be updated and transformed as planned.
The plan proposes ten key tasks, which are as follows:
(1) Renewal of old residential elevators.

For residential elevators that have been put into use for a long time, low configuration level, high operation failure rate, prominent safety hazards, and strong willingness of the masses to update, they will be updated, transformed or overhauled in combination with hidden danger investigation or safety risk assessment, and must meet the requirements of economy, safety and durability, stable operation, green environmental protection and smooth communication after renewal.
(2) Installing elevators in existing residences.
Combined with the promotion of urban renewal and the transformation of old communities, to meet the needs of aging. Adhere to the principles of government guidance, voluntary owners, territorial management, and standardized safety.
Comprehensively considering the residents' wishes, residential structural conditions, use functions, safety and economy and other factors, make overall arrangements and steadily promote the installation of elevators in existing residences, and the construction of the project shall not adversely affect the safety of the original structure.
Strengthen the approval and acceptance of new hoistways, evacuation channels and other related structures, and implement the main body of responsibility for use management and safety maintenance before the elevator is installed.
Encourage the installation of elevators in the way of leveling the entrance to achieve barrier-free access.
(3) Renewal of water supply facilities and equipment.

Coal-fired boilers that exceed their service life, do not meet the energy-saving level or level 2 standards of industrial boilers, and do not meet the flue gas emission standards.
Focus on eliminating coal-fired boilers of 35 steam tons / hour and below, and give priority to transforming them into various types of heat pump units.
In accordance with the requirements of "Technical Conditions for Hot Water Heating Network Thermal Station Equipment" (GB/T38536), "Energy Efficiency Limit and Energy Saving Evaluation Value of Clean Water Centrifugal Pump" (GB19762), "Urban Heating Substation Unit" (GB/T28185) and other requirements,
Modernization of heat exchangers and pump motors that have exceeded their service life and do not meet the energy efficiency standards.
Actively promote the transformation of heat metering, in accordance with the relevant requirements of heat metering, update the installation of metering devices and other equipment.
(6) Standardized and updated construction of liquefied petroleum gas filling stations.
In accordance with the requirements of "Gas Engineering Project Code" (GB55009) and "Liquefied Petroleum Gas Supply Engineering Design Code" (GB51142),
Renovation and transformation of equipment that fails to pass the inspection, exceeds the service life, is seriously damaged to the main components, is seriously aging and corroded, has potential safety hazards and has no maintenance value, including storage tanks, loading and unloading arms, compressors, filling systems, LPG pumps, fire pumps and pipeline valves, fire protection and automatic control equipment, etc.;
Update cylinders that do not meet the requirements of the current "Liquefied Petroleum Gas Cylinder" (GB5842).
Encourage the implementation of intelligent upgrading construction on the basis of renovation and transformation, and improve the level of automation, informatization and intelligent operation in the field of liquefied petroleum gas.
(7) Construction of urban lifeline projects.
