At present, the concept of “green water and green mountains are golden mountains and silver mountains” has been deeply rooted in the hearts of the people, and green development has become the consensus of all walks of life. This year’s National Conference on housing and urban rural development defined the overall requirements and key tasks for 2022, and proposed to continue to carry out the action of creating green buildings and implement the goal of carbon peaking and carbon neutralization. In the work of local governments, promoting the green and low-carbon development of the construction industry has become a prominent highlight.
In the work deployment around the country, “green building creation action” has become a high-frequency word, drawing a “timeline” for the integration of green buildings into people’s life. As a strong construction Province, Zhejiang province promotes the rapid development of green buildings, and urban green buildings account for 97% of new civil buildings. The Zhejiang provincial Conference on housing and urban rural construction clearly proposed to accelerate the creation of green buildings, require new civil buildings to fully implement the green building standards, and improve the green building standards for large public buildings and government public welfare buildings.
Like Zhejiang Province, Jiangsu, Hubei, Anhui and other provinces also proposed to speed up the creation of green buildings, and made mandatory requirements for the implementation of green building standards for new civil buildings. Jiangsu Province proposes that by 2025, new buildings should be designed and built in full accordance with ultra-low energy consumption standards, increase energy efficiency by 30% on the basis of 30% in 2020, build a number of high-quality green building projects, create a number of energy-saving, low-carbon, smart and livable green building demonstration areas, and incorporate the energy-saving transformation of existing buildings into green buildings.
Hubei Province not only promotes government investment projects and large public buildings to enforce Star green building standards, but also encourages real estate projects to implement Star green building standards; It is planned that by 2025, the energy efficiency level of new buildings will be increased by 15%, and the completed area of green buildings will account for 100%. Anhui Province has incorporated the implementation of green building standards for civil building construction into the project construction management procedures, strictly supervised the design and construction of new urban buildings in full accordance with green building standards, and required that the completed area of green buildings account for more than 70% of new civil buildings in 2022.
The carbon emission of China State Construction Engineering Corporation Limited(601668) industry accounts for more than half of the country’s total carbon emission, and it is a real “large” carbon emission. The National Conference on housing and urban rural development proposed to “implement the goal and task of carbon peak and carbon neutralization”, accelerate the transformation of the construction mode of “massive construction, massive consumption and massive emission”, and promote the green development of urban and rural construction.
All localities actively explore the road of “carbon reduction”, promote building energy conservation and promote green development. Shanghai, Hainan and other places strive to promote the green transformation of existing buildings and improve building energy efficiency. Shanghai will explore the establishment of a quota management mechanism for residential building operation energy consumption, guide the improvement of existing residential efficiency and promote the green transformation of existing residential buildings; Establish a supervision mechanism for green residential users and incorporate the indicators related to residential green performance and full decoration quality into household acceptance management. Hainan Province will synchronize the green transformation of existing buildings with the transformation of old urban communities, the transformation of dilapidated rural houses and seismic reinforcement, and explore the development of ultra-low energy consumption, near zero energy consumption and low-carbon buildings, which will take a solid step in promoting the green development of urban and rural construction.
At the same time, accelerating the application of green materials has become an important starting point for promoting the green transformation of the construction industry. Jiangxi, Guangdong, Guangxi and other places have actively carried out the evaluation and certification of green building materials, issued the product catalogue of green building materials, established the tracking and acceptance mechanism of the whole process of design, construction and acceptance of green building materials, and required to take the lead in adopting green building materials in government invested projects such as green buildings and prefabricated buildings, so as to improve the application proportion of green building materials in new urban buildings. Foshan, Guangdong Province also carried out the “pilot project of government procurement supporting green building materials and promoting the improvement of building quality”, formulated and issued 30 reform measures in the field of project bidding and government procurement, implemented remote bid evaluation, upgraded the supervision platform, established a big data analysis system, and strengthened the whole process supervision of trading projects, It provides a good policy environment and market environment for the pilot of green building materials.
In order to solve the common problems of poor building quality, high energy consumption and low energy efficiency in China’s rural housing construction, many places take “encouraging the construction of green rural housing” as the development focus. Sichuan, Shaanxi and other places actively encourage the construction of green agricultural houses. Sichuan Province fully implements the design standard of 65% energy efficiency of residential buildings, and advocates the use of light steel prefabricated, prefabricated concrete and modern rammed earth technology to build green rural housing in places where conditions permit; Shaanxi Province has vigorously promoted the applicable technologies of green rural housing construction, guided and encouraged the construction of rural self built houses with reference to the green building standards, carried out the application demonstration of rural renewable energy buildings in county units, promoted the pilot construction of appropriate energy-saving technologies such as passive solar houses and renewable energy heating, and improved the living environment.
In addition, many provinces continue to explore technical measures for the application of renewable energy buildings, promote ultra-low energy consumption and near zero energy consumption buildings, and develop zero carbon buildings.
Fujian Province vigorously promotes the integrated application of Cecep Solar Energy Co.Ltd(000591) photovoltaic photothermal, high-efficiency air source heat pump, water source heat pump and other renewable energy buildings, and encourages the integrated development of intelligent photovoltaic and green buildings. Yunnan Province will develop the distributed and integrated application of Cecep Solar Energy Co.Ltd(000591) photovoltaic in urban and rural buildings, explore and promote the research and development, standard formulation and engineering application of near zero energy consumption building technology in mild areas, promote low-carbon building technology and promote the development of low-carbon buildings. Heilongjiang province takes the development of passive ultra-low energy consumption buildings as an important starting point to achieve “carbon peak and carbon neutralization” in the field of housing and urban and rural construction, and promotes the green and low-carbon transformation of the construction industry.
The concept of green and low-carbon runs through the development picture described by various places. As an important carrier to comprehensively promote green development, China State Construction Engineering Corporation Limited(601668) industry is constantly creating a “green miracle” and becoming a powerful driving force to promote the construction of a beautiful China.
