Tang Junjie, member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC) : Promote carbon neutrality in the construction sector and let the people live in high-quality good houses

This year's National Two Sessions，Tang Junjie, member of the National Committee of the Chinese People's Political Consultative Conference and president of the Beijing First Agricultural Food Group Knowledge Association, brought about the large-scale promotion of Low carbon/zero carbon buildings around hot topics such as carbon peak carbon neutrality，A proposal to enable the people to live in good quality housing.，And on the relevant content accepted the China industry Information News Network, Made in China reporter interview。

"With the continuous development of the economy and the improvement of residents' living standards, the proportion of building carbon emissions in the whole society will be further increased.。In order to promote peak carbon neutrality in the construction sector, the construction of low carbon/zero carbon buildings needs to be accelerated。Tang Junjie said that the construction sector is one of the main areas of carbon emissions in China。In 2021, China's total annual carbon emissions will be about 10.5 billion tons of CO2, of which the carbon emissions in the building operation stage will be about 23 percent.500 million tons of CO2, accounting for 22% of China's total carbon emissions。Vigorously develop low-carbon buildings and zero-carbon buildings, and actively promote the depth of energy saving and carbon reduction in the construction field is an important measure to implement the peak carbon neutrality in the construction field and promote the high-quality development of energy saving and carbon reduction in the construction industry。

Tang Junjie introduced，The national standard "Zero carbon building Technical Standard" has been completed，The building in the standard is based on the national mandatory energy conservation code，Further improve energy saving and carbon reduction performance，Use renewable energy to reduce carbon emissions，And can be combined with carbon emission rights trading and green electricity trading and other ways，Achieve low carbon, near zero carbon, zero carbon building goals。同时，The "14th Five-Year Plan" national key research and development Plan "Zero carbon building control indicators and key technology research and application" project was carried out，It has formed zero carbon building control indicators, whole process technical strategies and evaluation methods, carbon emission calculation tools, and several low carbon/zero carbon demonstration projects，It has laid a good foundation for the large-scale promotion of low carbon and zero carbon buildings。

Tang Junjie believes that at present, China's low carbon/zero carbon building promotion faces the following two problems。

One is the industry's lack of understanding of the definition and technical path of low-carbon/zero-carbon buildings。Although the development goal of low-carbon/zero-carbon buildings has repeatedly appeared in various policies of the housing system, there are still deficiencies and deviations in the industry's understanding of the concept, application scope and implementation technology path of low-carbon/zero-carbon buildings。The performance-based design method adopted by low carbon/zero carbon buildings requires that reasonable objectives should be established at the early stage of design and relevant technical requirements should be implemented。

Second, market players lack of motivation for the construction of low-carbon/zero-carbon buildings。Zero-carbon buildings put forward higher requirements for carbon emission control in the whole life cycle of buildings。From the perspective of cost increment, the cost increment of low-carbon/zero-carbon buildings is generally higher than that of ordinary energy-saving buildings and green buildings, reaching a maximum of nearly 1500 yuan /m2。According to the survey statistics, the current local funding support policies for low-carbon/zero-carbon buildings are less, relying on the construction side to raise funds, there is a lack of construction power。

"To promote carbon neutrality in the construction sector, so that people can live in high-quality good houses, there is an urgent need to scale up the construction of low carbon/zero carbon buildings.。"Tang Junjie said。To this end, she put forward the following three suggestions。

First, improve the low-carbon/zero-carbon building construction system。In order to further promote the scientific understanding of low carbon/zero carbon buildings in the industry and society, and set reasonable targets according to the project situation。It is suggested that the Ministry of Housing and Urban-Rural Development should take the lead in formulating a system for the promotion of low-carbon/zero-carbon buildings, implement the implementation of relevant standards for low-carbon/zero-carbon buildings, and advocate the concept of low-carbon building design。Combined with the building energy conservation work, the development goals and main tasks of low-carbon/zero-carbon buildings are defined。Improve the low carbon/zero carbon building performance evaluation methods, with the assessment as the starting point, and increase the importance of governments at all levels of low carbon/zero carbon building construction。In terms of promoting the strategy, the local housing and urban and rural construction departments will take the lead in overall planning, reasonable layout, adhere to the pilot first, from point to point, step by step implementation, and gradually achieve the large-scale development of low-carbon/zero-carbon buildings。

The second is to strengthen professional guidance on the promotion of technology paths and build a zero-carbon building technology innovation system。In the selection of low-carbon/zero-carbon building technology path, it is necessary to increase the guidance of professional and technical personnel, build a market-oriented, enterprise-dominated, and deeply integrated low-carbon/zero-carbon building technology innovation system, improve the technical quality and operational efficiency of the low-carbon/zero-carbon industrial chain, and reduce technical costs。Governments at all levels should take the lead in setting an example, forcing new investment in public welfare public buildings and public institutions to meet the technical requirements of low carbon and zero carbon buildings, actively promoting the implementation of low carbon/zero carbon building projects, and comprehensively improving the development level of building energy conservation and carbon reduction。

The third is to introduce strong and effective incentives to support low carbon/zero carbon buildings as soon as possible。Policy and financial support for the development of low carbon/zero carbon buildings will form a powerful driving force。To give full play to the role of government leadership and market mechanisms, housing and urban and rural construction departments to strengthen communication with development and reform, finance, taxation and other departments, strive to implement financial funds, prices, taxation and other support policies, low carbon building, zero carbon building projects to give policy support and financial awards。

Member Tang Junjie: Establish a green "big reserve" thinking

A few days ago, seven ministries and commissions jointly issued a document to carry out the "Youth guardian China's food" action, calling on young people across the country to save food。Tang Junjie, a member of the National Committee of the Chinese People's Political Consultative Conference and president of the Beijing First Agricultural Food Group, also brought a proposal to "save" food: develop low-temperature storage technology for rice to ensure national food security。

"The conventional storage period is 2 to 3 years, and from the national point of view, the food loss caused by traditional farmers' grain storage accounts for 3% to 5% of the total reserve.。The low temperature storage technology can extend the storage life to 3 to 4 years, and the germination rate of rice stored for half a year can still be kept above 91%。Tang Junjie said that the "low-temperature quality storage technology" is of great significance to China's grain loss reduction, to ensure the high-quality and stable operation of the reserve system, and to ensure national food security at a high level。

How to strengthen the research, application and popularization of this technology？Tang Junjie suggested that we should promote the research and development and innovation of rice low-temperature storage technology, deepen international exchanges and cooperation, and increase the construction of operation and maintenance personnel training and evaluation system。

"Build a multidisciplinary co-creation platform for refrigeration technology, air conditioning engineering and food engineering, set up a national low-temperature storage technology innovation fund, and actively guide scientific research institutions and enterprises to increase research and development investment in key technologies.。"Tang Junjie suggested，It is necessary to establish a green "big reserve" thinking，It can be led by the Chinese Society of Refrigeration，Work together with universities, research institutes and large grain storage enterprises to tackle key problems，To deal with the technical problems brought by different varieties of rice, different climates and environments，Completed research and development and engineering demonstration of rice low-temperature storage technology and equipment。
