Implementation Plan of Carbon Peak in Urban and Rural Construction in Hubei Province in 2023

The field of urban and rural construction is a major carbon emitter. On August 16, the Provincial Department of Housing and Urban-Rural Development and Reform Commission jointly issued the "Hubei Province Urban and Rural Construction Field Carbon Peak Implementation Plan", which clarified the overall goals and eight key tasks.

The plan proposes that carbon emissions in the province's urban and rural construction will reach a peak before 2030. The institutional mechanism and policy system for green development in urban and rural construction have been basically established, all new civil buildings in cities and towns have been built into green buildings, the efficiency of building energy utilization has been further improved, and the growth trend of building energy consumption and carbon emissions has been effectively controlled.

　　The implementation plan defines eight key tasks:

The first is to promote the green and low-carbon development of urban construction. From the three aspects of promoting the construction of green ecological city, improving the operation efficiency of urban infrastructure, and promoting the construction of green low-carbon community, this paper puts forward requirements for urban form, density, functional layout and construction mode, as well as infrastructure construction, urban renewal and garbage disposal, and defines the specific quantitative targets such as the average road density of urban built-up areas and the proportion of green community creation.

The second is to improve the energy efficiency level of new buildings. From the aspects of implementing building energy efficiency standards, promoting ultra-low energy consumption building pilot projects, strengthening building energy-saving transformation and operation management, the key tasks of improving building energy efficiency level are clearly defined, and the target requirement of "increasing the energy efficiency level of new buildings by 15% by 2025" is put forward.

The third is to promote the quality and efficiency of green buildings. The ways and methods of high-quality development of green buildings are clarified from the aspects of in-depth development of green building creation actions, promotion of standardized management of green buildings, and improvement of green building quality.By 2025, the proportion of green buildings in new urban civil buildings will reach 100 percent, and the proportion of star-rated green buildings will reach 20 percent.”。

Four is to strengthen the application of renewable energy. From the aspects of promoting the diversified use of renewable energy and promoting the application of solar energy buildings, it puts forward requirements for the large-scale and efficient application of renewable energy buildings, and makes it clear that "by 2025, the replacement rate of renewable energy in urban buildings will reach 8%".

Five is to strengthen the building energy saving operation management. From the aspects of strengthening the monitoring and management of building energy consumption and improving the energy efficiency of equipment and facilities, strengthening the operation and management of building energy conservation proposes that by 2030, the overall energy efficiency of the electromechanical system of public buildings will be increased by 10% from the current level.

Six is to optimize the structure of building energy. From the implementation of building electrification projects and the development of new building power systems, the energy consumption structure will be further optimized. By 2030, the province's urban building electricity will account for more than 65% of building energy consumption.

　　Seven is to promote green low-carbon construction. The implementation path of promoting green and low-carbon construction is put forward from the aspects of prefabricated buildings, industrialization and intelligent construction of new buildings, and improving the application of green building materials. It is required that by 2025, new prefabricated buildings in the province account for more than 30% of the new construction area.

Eight is to promote green county and rural construction. Focusing on the aspects of green and low-carbon county towns, creating beautiful and livable villages, and promoting the construction of green and low-carbon rural houses, measures to promote the green development of county towns and villages are proposed, requiring that "by 2025, new rural houses have design plans or adopt standard atlases. The proportion reaches 70%" and other target tasks.

By 2030,The new residential building body reaches 75% energy saving requirementThe new public building body meets the energy saving requirement of 78%.

2. Promote the pilot demonstration of ultra-low energy consumption buildings. We will continue to promote the pilot work of ultra-low energy consumption buildings in "one main and two wings" cities, and encourage other cities to carry out the pilot work simultaneously. Guide state office buildings, large-scale public buildings, government-invested public welfare buildings, and other public buildings where state-owned funds participate in investment and construction, and actively carry out pilot demonstrations of near-zero energy buildings, low-carbon buildings, and zero-carbon buildings. By 2025, the province will complete an ultra-low energy consumption building area of 1.2 million square meters, and the pilot work will form a feasible experience. By 2030, the province will complete an ultra-low energy consumption building area of 3 million square meters.

3. Improve the energy saving level of existing buildings. Combining urban renewal and the transformation of old urban communities, actively carry out energy-saving transformation of existing residential buildings, and guide residents to choose energy-efficient doors and windows, air conditioners and other parts and equipment. We will implement energy-saving renovation of public buildings on a large scale, and encourage qualified large-scale public buildings to be renovated in accordance with green building standards. Explore the market-oriented mechanism of green energy-saving transformation of existing buildings, and promote the government, residents, and social forces to reasonably share the funding mechanism for the transformation. Promote contract energy management, energy cost trusteeship and other models.
