The green and low-carbon development system and policy system have been basically established, the transformation of green and low-carbon construction has made significant progress, the energy-saving standards of new buildings have been further improved, and the new buildings have achieved full coverage of green buildings.

According to the Action Plan, by 2025, new civil buildings will fully implement the design standards of building energy consumption and carbon emission quota, and building energy efficiency will be increased by 30% on the basis of the current energy conservation standards.

With the establishment of the dual-carbon goal, the building carbon emission trading mechanism has become a hot spot again.

100% precast, 100% full decoration, 100% BIM technology, 100% precast and 100% full decoration in the Action Plan for the comprehensive promotion of green building materials in new civil buildings in 2030 have also been put forward by some provinces and cities, but 100% BIM technology is relatively rare at present, The previous requirements for similar indicators were only reflected in the “Plan for Accelerating the Digital High-quality Development and Building a Digital Pioneer City” issued by Jinan Municipal People’s Government in 2021.

Youlv think tank believes that the comprehensive electrification of buildings will be a major development trend in the future.

The first batch of public buildings to be included in the transaction system included 198 public buildings (large office buildings, shopping malls, tourist hotel buildings).

As shown in the figure above, the number of projects applying the BIM technology will reach 956, with a total investment of 1922.99 billion yuan, including 617 government investments, with an investment of 1069.663 billion yuan; There are 339 social investments with an investment amount of 853.327 billion yuan.

Under this mechanism, building owners undertaking the task of emission reduction can adjust the task of emission reduction through currency exchange, so as to achieve the purpose of reducing the cost of enterprise emission reduction.

As early as 2011, the National Development and Reform Commission issued the Notice on the Pilot Work of Carbon Emission Trading.

Under the building carbon emission trading system, carbon quotas become a scarce commodity.

According to the 2022 Shanghai Building Information Model Technology Application and Development Report issued by the Shanghai Municipal Housing and Urban-Rural Development Management Commission, a total of 2363 new projects will be applied for construction in 2021.

The energy-saving transformation of 200000 square meters of existing public buildings has been implemented, green production and lifestyle have been widely popularized, and the energy consumption structure of buildings has been continuously optimized.

On the contrary, due to the poor effect of carbon emission reduction in some high energy consumption buildings, the carbon quota obtained by them is not enough to offset their actual carbon emissions.

The proportion of star-level green buildings will reach more than 30%, and the new government-invested public buildings and large public buildings will all reach more than one star.” Shanghai’s Action Plan requires more.

After the release of the document, the National Development and Reform Commission agreed to carry out pilot projects in seven regions including Beijing and Shenzhen.

By 2025, the green building standards will be fully implemented for new urban buildings.

This is the third local policy specifically aimed at building energy conservation and low-carbon development since Anhui Province issued the Notice of Anhui Provincial Action Plan for Building Energy Conservation and Carbon Reduction on September 30 and Beijing issued the Work Plan for Building Energy Conservation and Carbon Reduction in Beijing and the Green Development Plan for Civil Buildings during the “Fourteenth Five-Year Plan” period on December 16.

This Action Plan has higher requirements and larger steps, which means a strong pilot.

The pilot projects in other regions are much the same as those in Shenzhen.

On December 22, 2022, the Action Plan for Low-Carbon Development in the Construction Sector of the New Portside Area of the China (Shanghai) Pilot Free Trade Zone was issued (hereinafter referred to as the Action Plan), proposing to consolidate the carbon-neutralization foundation of the construction sector by 2025.

Therefore, achieving “low cost carbon reduction” is the largest mechanism and ultimate purpose of building carbon emission trading.

Explore the carbon emission trading mechanism in the construction sector.

In 2013, Shenzhen launched a pilot project in the fields of industry, construction and transportation.

Youlv think tank predicts that more provinces and cities will try to carry out the building carbon emission trading in 2023.

This is also closely related to the fact that Shanghai has been vigorously promoting the BIM technology.

Summary To achieve carbon peak and carbon neutrality is an extensive and profound economic and social systemic change, and the development of energy-saving and low-carbon buildings is one of the key tasks..

In order to avoid punishment, they must buy in the construction carbon trading market to make up the difference.

By 2030, the Action Plan for the comprehensive electrification of new public buildings clearly proposes that the comprehensive electrification of new public buildings will be achieved by 2030.

In 2025, building energy efficiency will be increased by 30% on the basis of the current energy conservation standards.

Build a concentrated demonstration area of ultra-low energy consumption, and implement a demonstration project of ultra-low energy consumption buildings of no less than 2 million square meters.

Once the building owners have more carbon quotas, they will place the remaining carbon quotas in the building carbon trading market to trade and seek benefits, thus stimulating more building owners to adopt building energy conservation and emission reduction measures Update carbon emission reduction strategies such as equipment to obtain carbon quota.

100% green building two-star and above standards for new buildings are in accordance with the requirements of the Ministry of Housing and Urban-Rural Development’s Implementation Plan for Carbon Peak in the Field of Urban and Rural Construction, “We will continue to carry out green building construction activities.

Hebei Province has made some achievements in this regard, and has successively issued the Notice on Developing the Special Work of Financial Assistance to Realize the Value of Carbon Assets, and the Several Measures on Deepening the Realization Mechanism of the Value of Carbon Assets (Trial), It has effectively promoted energy conservation and carbon reduction in the construction field.
