Where is green building going in the 14th five year plan? So said representatives of the two sessions


In this year’s NPC and CPPCC sessions, “reaching the peak of carbon” and “carbon neutralization” attracted much attention

.

In order to cope with climate change, China has made solemn commitments such as “strive to reach the peak of carbon dioxide emissions by 2030 and strive to achieve carbon neutrality by 2060”

.

In this year’s government work report, “do a good job in carbon peak and carbon neutralization” is listed as one of the key tasks in 2021; “the 14th five year plan” will also speed up the promotion of green and low-carbon development

.

As a major carbon emitter, is the construction industry facing a crisis or an opportunity under the target of 3060? Will green building usher in a leap forward development? Hong Jie, deputy to the National People’s Congress, chairman and President of sankeshu, said: “in order to achieve the goal of carbon peak by 2030 and carbon neutralization by 2060, we must vigorously develop green buildings to save resources, protect the environment and reduce pollution to the greatest extent in the whole life cycle of buildings.” Hong Jie said that according to the current data forecast, the national building carbon peak time is 2040, which is 10 years behind the national carbon peak target

.

Moreover, China’s total construction volume continues to grow, with 16 billion square meters of new building area each year being high energy consuming buildings with only 33% energy utilization rate

.

Therefore, it is impossible to reduce building energy consumption and carbon emissions and vigorously develop green buildings It’s very slow

.

Representative Zhu Huiying: promoting green development with building energy conservation “quality improvement, green transformation and mechanism innovation have become new development concepts of building energy conservation industry.” Zhu Huiying, deputy to the National People’s Congress, member of the Central Committee of Jiusan Society and professor level senior engineer of Guangxi Zhuang Autonomous Region Institute of building science research and design, said that this concept will put forward higher and stricter requirements for building energy conservation and green building development

.

“With the development of economy and society and the continuous improvement of people’s living standards, the increasing trend of building energy consumption will not change

.

But its rising rate needs to be controlled to form a more gentle curve

.

” Zhu Huiying said

.

According to the International Energy Agency’s calculation of energy consumption and emissions in the global construction sector, in 2018, the terminal energy consumption related to construction (including housing construction and infrastructure construction) and building operation in the global construction industry accounted for 35% of the global energy consumption

.

In China, the energy consumption of construction and operation accounts for 36% of the total energy consumption of the whole society in 2018, which is close to the global proportion

.

In Zhu Huiying’s view, we can continue to promote building energy conservation and consumption reduction from two aspects

.

First, accelerate the development of new building industrialization, especially prefabricated buildings, and use modern technology to reduce the energy consumption of building construction and infrastructure construction

.

The second is to reduce the energy consumption of building operation by improving the construction and management level of green buildings, improving the energy efficiency standard level of new buildings, improving the energy efficiency of existing buildings, and promoting the high-quality application of renewable energy

.

Zhu Huiying said that the integration development of green buildings, ultra-low energy consumption buildings, smart buildings and healthy buildings has become the mainstream trend

.

We should continuously improve the building energy utilization efficiency, reduce the rapid growth of building energy consumption, and realize the steady decline of building energy consumption intensity

.

Fully absorb the concept of healthy building, ecological building and low-carbon building development, pay attention to improving the living quality, comfort and health and epidemic prevention performance of buildings, and accelerate the high-quality development of green buildings

.

In addition, we should increase the application of key technologies, promote the continuous innovation and development of science and technology, seize the opportunities, and meet the difficulties and challenges

.

Yang Weijun, member of the National Committee of the Chinese people’s Political Consultative Conference (CPPCC), vice chairman of Hunan Provincial Committee of the democratic revolution and vice president of Changsha University of technology, believes that at present, there are still some problems in the development of green buildings, such as the imperfect construction of supporting laws and regulations, the need to strengthen the implementation of policy support, and the imbalance of overall and coordinated development

.

In order to promote the great development of green buildings in Hunan Province during the “14th five year plan”, he put forward the following suggestions: improve the work promotion mechanism

.

Strengthen the legislative guarantee, amend the “Regulations on energy efficiency of civil buildings in Hunan Province” as soon as possible, promote the development of green buildings from the aspects of construction, rewards and punishments, goals, etc., solve the problems of unbalanced development, low implementation rate, and inadequate supervision, improve the leadership mechanism, establish the provincial leading group for promoting green buildings, create the work force of department coordination and linkage, strengthen the assessment and supervision, and promote the development of green buildings The completion of the task of promoting green building in cities and prefectures will be included in the annual performance appraisal system of the provincial Party committee and the provincial government

.

Increase policy support

.

Set up green building development special fund, co-ordinate green related funds of various departments, increase financial direct investment, formulate corresponding policies, and give different incentive policies such as floor area ratio award and financial subsidies to different types of green buildings by star and stage; innovate the use of tax, financial and other tools, enlarge the effect of financial investment, fully mobilize the enthusiasm of social capital participation, and guide the development of green buildings We will invest and operate green building projects by means of government and social capital cooperation and franchise

.

Improve the supporting system

.

Establish and improve the supporting system to promote the development of green buildings: the “green” control system in the whole process of new project land transfer, project approval, planning approval, construction drawing review, construction supervision and completion acceptance; the system of building energy consumption quota management, over quota price increase, energy-saving trading in the process of building use; the approval of existing building demolition, the establishment of energy-saving reconstruction projects, and energy-saving transaction Supervision and management system for energy transformation project implementation; development of shallow geothermal energy, solar energy and other renewable energy building application and management system; green building evaluation and identification, green building materials, equipment evaluation and certification, building energy efficiency measurement and control, energy conservation identification rules, prefabricated building and green building consulting service system; green building product certification system

.

Strengthen the ability of technical support

.

Improve the existing standards and evaluation system, formulate and improve technical standards, release and timely update the directory of promotion, restriction and prohibition of use, establish a long-term mechanism of building energy consumption statistics and energy efficiency audit, organize and carry out building energy efficiency evaluation; make diversified use of green building technology, rely on the construction of smart city and ecological city, and continuously promote the scientific research and innovation of green building, Comprehensively develop and utilize land-saving, energy-saving, water-saving, material saving and environmental protection technologies, support the construction of green building technology industrialization base, promote the green operation of building life cycle, and bring the green operation into the legislative assessment and normalized management

.

We will vigorously develop shallow geothermal energy

.

Accelerate the development of shallow geothermal energy promotion and application implementation plan, funding subsidies relief and other policy support measures and related assessment, accountability measures

.

It is encouraged to explore the R & D and application demonstration of the “geothermal +” third generation technology with geothermal energy as the main body and the integration of various clean energy sources, so as to improve the development and utilization efficiency of geothermal energy and the proportion of replacing traditional fossil energy, and promote the healthy, rapid and safe development of shallow geothermal energy

.

Representative Peng Shou: accelerate the application of green materials in building and help carbon neutralization

.

This year’s government work report clearly pointed out that we should do a solid job in achieving carbon peak and carbon neutralization, and constantly optimize the industrial structure and energy structure

.

In this regard, Peng Shou, deputy to the National People’s Congress, academician of the Chinese Academy of engineering and chairman of China Building Materials International Engineering Group, proposed to accelerate the application of green materials in building and help carbon neutral

.

“Carbon peaking and carbon neutralization are major decisions made by the state to implement the new development concept

.

The development of green buildings is conducive to promoting the transformation and upgrading of related industries, reshaping the production and lifestyle, and is crucial for the early realization of carbon peaking and carbon neutralization.” Peng said

.

Although the R & D and production of green materials have made an important breakthrough, compared with foreign developed countries, there is still a big gap in the application and popularization of green materials and green building in China.
