“The enterprise itself has the awareness of reducing carbon, but it still needs investment to do so. According to the calculation, it needs an additional investment of 700 ~ 1000 yuan per square meter of construction to achieve low carbon, which makes the enterprise’s initiative not strong enough.”
Shen Qunhui, deputy to Shanghai Municipal People’s Congress and director of Changning District Hongqiao and Zhongshan Park Regional Function Development Office, has many years of front-line experience in the field of environmental protection. In her opinion, as a megacity with a large number of buildings, Shanghai promotes an important area of low-carbon, that is, carbon emission reduction of public buildings, but low-carbon means more investment. Therefore, she suggested that relevant departments should introduce more targeted support policies and combine them with green finance to encourage more enterprises to participate in carbon emission reduction investment in public buildings.
According to the work report of Shanghai municipal government, in 2022, Shanghai will actively implement the goal and task of carbon peak and carbon neutralization, and orderly promote the special action of carbon peak in key fields and industries. These include promoting green construction methods, developing energy-saving and low-carbon buildings, and implementing energy-saving transformation of public buildings of 4 million square meters. At the same time, 3000 new energy buses will be put into operation to fully complete the standardized transformation of inland river shore power.
Mou Zhenying, deputy to the Shanghai Municipal People’s Congress, executive deputy general manager of Shanghai Shanghai Shentong Metro Co.Ltd(600834) (600834. SH) Co., Ltd. and chairman of Shanghai Metro New Energy Co., Ltd., said that there are still two problems in carbon emission reduction in the construction field in Shanghai. First, new buildings still meet the energy-saving standard in theoretical calculation, and all disciplines are designed according to the maximum load standard, However, there are great differences between the actual operation and the design theoretical value. However, it is difficult to implement the transformation of high-energy consumption buildings in stock. Due to the complex property rights, unclear transformation subjects and difficult fund implementation, it is difficult to promote the implementation of energy-saving transformation with energy conservation and carbon reduction as the cut-off point.
“There is a widespread problem of energy conservation, reconstruction and light operation, and there is a lack of effective means for energy conservation supervision in the operation stage.” Mou Zhenying said that the total energy consumption in the building life cycle is heavy, and the proportion of operating energy consumption and carbon emission usually exceeds 60%. However, in operation, the actual benefits of building energy conservation and emission reduction are often greatly reduced due to the diversity of subjects, unclear responsibilities, weak awareness and unclear linkage of economic interests.
Therefore, Mou Zhenying suggested to strengthen the research on low-carbon and zero carbon standard system, explore the technical path of building low-carbon transformation, and promote the integrated development of renewable energy buildings. In addition, carry out pilot demonstration of low-carbon buildings and low-carbon communities, and explore the establishment of a refined carbon emission trading mechanism suitable for different types of subjects in the construction field.
Zhou Yu, deputy to the Shanghai Municipal People’s Congress and senior project manager of Sinopec Shanghai Engineering Co., Ltd., proposed to accelerate the transformation of power supply structure in Shanghai and vigorously develop renewable energy such as photovoltaic and hydrogen energy. Encourage the construction of photovoltaic power generation facilities in various buildings and houses, strengthen the system integration of renewable power, link the charging network with electric vehicles to form an energy storage network, deal with the uncertainty of renewable energy and ensure the maintenance of power supply security.
She also proposed to accelerate the realization of power substitution in industry, construction and transportation and effectively reduce carbon emissions. Establish a “network source and load storage” energy system in the construction of new towns, urban renewal and the development of industrial parks, make full use of waste heat and waste heat, and further increase the recycling of resources. At the same time, she also suggested that Shanghai take the lead in pilot cultivation and incorporate hydrogen energy into the management system. “I hope to see more and more hydrogen energy buses, buses and heavy long-distance transport vehicles in Shanghai”.
Han Ruobing, deputy to the Shanghai Municipal People’s Congress and general manager of Shanghai rouwei Material Technology Co., Ltd., proposed to comprehensively promote the digital construction and transformation of Shanghai municipal government buildings and large public buildings, establish all kinds of building big data analysis algorithms, and unify building energy efficiency and carbon emission labels. Secondly, set up special funds to steadily promote the green and low-carbon transformation of existing government buildings and public buildings in Shanghai, and create more model projects and promotion paradigms.
In addition, accelerate the formulation of local standards and the supply of relevant legislation, give full play to the advantages of the financial center, and explore the financial scheme of existing construction reconstruction funds. For example, learn from international experience, encourage banks, trusts and other financial institutions to explore and promote “green loans” and other financial instruments to meet the needs of construction owners for reconstruction funds.
Guo Kangxi, deputy to the Shanghai Municipal People’s Congress and chairman of the Shanghai Hong Kong Group, also paid attention to the huge building volume in Shanghai. He said that Shanghai has a huge building volume, so building energy conservation and environmental protection is more necessary. We should pay attention to connotative expansion of reproduction, increase support for technological innovation, and invest in greener equipment to improve efficiency and reduce carbon emissions.
In the past year, Shanghai has formulated the implementation opinions and implementation plan of carbon peak neutralization, and the national carbon emission trading market has been put into operation in Shanghai. Shanghai, which launched the implementation of the eighth round of three-year action plan for environmental protection, has completed the treatment of volatile organic compounds in 1042 industrial enterprises, promoted the application of 254000 new energy vehicles, reaching 677000 in total, and ranked first in the evaluation of the effectiveness of pollution prevention and control.
