2010 China Real Estate and Municipal Engineering Construction Development Summit Forum and Building Energy Conservation and Emission Reduction “Eleventh Five-Year†inventory of achievements has been held in Beijing recently. The event was jointly organized by the China Real Estate Association, the China Municipal Engineering Association, the China Architectural Design Institute, and the China Building Energy Conservation and Emission Reduction Industry Alliance. The theme was “Low Carbon City Construction†and “Building Energy Saving and Emission Reduction†through the inventory of “Eleventh Five-Year Planâ€. The process of energy conservation and emission reduction explored how energy conservation and emission reduction could be used to shake up the construction of low-carbon cities, as well as ways to instigate the construction of low-carbon cities. At the same time, a forward-looking outlook for the “12th Five-Year Plan†energy-saving planning was made.
Liu Zhifeng, President of China Real Estate Association:
Improving the service life of buildings The most important issues facing current building energy conservation: First, the service life of buildings is far less than the actual life span, and the results of energy conservation and emission reduction are greatly reduced, resulting in great waste of resources and energy. The second is the slow progress in the reform of heat metering charges, and it is difficult to retrofit existing buildings. Third, the level of housing industrialization is relatively low, resource consumption is high, and the waste of secondary decoration is staggering. Fourth, the rural building energy-saving work has not yet started. Fifth, energy saving design standards are not perfect. Outstanding problems in the above five aspects have seriously affected the further and orderly progress of building energy conservation in China.
To solve the above problems, vigorously promote energy conservation and emission reduction of buildings, and take the road of sustainable development. During the “Twelfth Five-Year Plan†period, we must establish two concepts, pay attention to two overall plans, and proceed from five aspects.
First of all, we must establish the concept of saving the biggest improvement in the service life of buildings. If the service life of our buildings is doubled, we can save roughly half of the resources and energy for building materials production. The second is to establish the concept of comprehensive consideration of building energy conservation from the planning, design, construction, use, maintenance and demolition of the entire process of reuse and the entire life cycle of the building. After some of the entire houses in developed countries were dismantled, the average recycling rate reached 80%. Most of them became construction waste, and they also occupied a large number of places for landfill.
At the same time pay attention to two co-ordination. The first one is to co-ordinate new construction and existing buildings. The second is to coordinate the construction of urban and rural areas and change the situation of heavy townships and light townships.
Let me talk about which of the following five aspects we will start from:
On the one hand, starting from planning to build long-life, high-quality buildings. Planning is the foundation for improving the service life of buildings, and it is the leading leader in the construction of long-life, high-quality buildings. Ensure that the planning is rigorous, comprehensive, scientific, and maintain the mandatory and seriousness of the plan. Once the plan is determined to be strictly enforced, and accountability is strengthened, it is necessary to make adjustments to strictly implement the legal procedures, so that it is open and transparent, in the middle of urban planning. It is necessary to partition scientific functions, build a multi-purpose community that integrates residence, commerce, and office work, actively promote urban complexes, and reduce traffic energy consumption.
Aspect 2: Starting from the transformation of residential development methods and building advanced manufacturing industries, we must vigorously promote the modernization of the housing industry and realize the transformation of the housing industry from traditional construction to advanced manufacturing.
Aspect 3: Starting from the renovation of existing buildings and rejuvenating the old houses, we must vigorously promote the maintenance and renovation of existing buildings, combining energy-saving transformation with upgrading of building functions and the transformation of the urban environment, avoid large-scale demolition and construction, and accelerate urban development. Heating system reform, improve the enthusiasm of development companies to build energy-saving buildings, and promote the behavior of residents to save energy.
Aspect 4: Start with residential innovation and promote industrial development with science and technology.
Aspect 5: Starting from the systems and mechanisms, strengthening policy support and resource integration, the first is to increase the guidance and support of financial and taxation financial policies, and to support the development of green buildings; the second is to establish and improve the national building energy efficiency statistics construction and evaluation system. It is necessary to strengthen the supervision of energy saving in state organs, office buildings, and large public buildings; the third is to integrate resources and establish industrial cooperation and exchange platforms. Industry associations should make achievements in building energy conservation, and in particular, they should play a role in resource integration. It is necessary to promote the use of a building energy measurement unit that is more easily understood by the general public and calculate the amount of energy consumed in daily life in degrees (electricity), tons (water), and cubic meters (gas), so that the energy efficiency of buildings can be truly realized. It is reflected in the lives of ordinary people.
Deputy Director of the Department of Regulation, National Development and Reform Commission Hao Yafeng:
Reflections on the Development Direction of Energy Conservation in the Twelfth Five-Year Plan We are currently working hard on the preparation of the “12th Five-Year Plan†for energy-saving and emission-reduction planning. We will initially consider the overall thinking of the “12th Five-Year Plan†energy-saving work, guided by the scientific concept of development, and focus on accelerating Transform economic development methods and reduce energy consumption intensity to control the combination of total energy consumption, form a forceful mechanism for promoting scientific development, combine organically the implementation of responsibilities, strengthen the legal system, and improve policies, form an effective incentive and restraint mechanism, and adjust Optimize the industrial structure, promote energy-saving technological advancement, strengthen the combination of energy-saving management, greatly increase the efficiency of energy use, and speed up the construction of energy-saving enterprises that take the main body, government-led, market-driven, society-wide participation, and adaptation to the requirements of the socialist market economy. Effectiveness mechanism.
First, it is necessary to implement the target responsibilities, significantly reduce the intensity of energy consumption, and the intensity of carbon dioxide emissions as an important constraint indicator, and fully consider the regional economic development level, industrial structure, and energy-saving potential, and determine scientifically and reasonably “twelfth five years†and next year. The energy-saving goals were implemented in each region and the evaluation and assessment methods were improved.
The second is to reasonably control the total amount of energy consumption, improve the industry's access threshold, and strictly review the energy conservation assessment of fixed asset investment projects.
The third is to improve the policy system and policy mechanism, promote the reform of resource product prices, form price formation mechanisms that reflect resource scarcity, supply and demand relations, and environmental costs, increase financial and taxation financial support for energy conservation, and comprehensively reform resource taxes. Energy-saving trading pilots, market-oriented energy conservation management mechanisms such as energy efficiency labeling for product leaders, energy conservation in accordance with the law, and implementation of laws and regulations such as the Energy Conservation Law, Civil Building Energy Conservation Regulations, Public Institutions Energy Conservation Regulations, and the improvement of supporting regulations and standards, Strengthen the supervision and inspection of energy conservation law enforcement, ensure the implementation of various systems, and stop all kinds of waste of energy. To mobilize all-round energy conservation is to further strengthen the publicity and education of the legal system. One is to increase the people's sense of urgency, and the other is to use energy-saving and environmental-friendly consumption patterns and lifestyles, and to be healthy.
Li Zuojun, Director of the Institute of Resources and Environmental Policy of the Development Research Center of the State Council:
Eight strokes to respond to the "12th Five-Year" low-carbon new situation In the early period of the "12th Five-Year Plan," we must undergo a difficult adjustment process. Then we will usher in a new round of development opportunities. What should companies do under such a new situation? I think there are the following eight measures:
Countermeasure 1: Take new opportunities and seize these three opportunities. One is the new opportunities brought by international industrial transfer and international industrial reorganization. Second, this crisis is also brewing a new world-wide technology ** and breakthroughs, mainly energy saving and environmental protection, as well as new energy, low Carbon and other technologies, then the breakthrough of these new technologies has also brought new opportunities for us to provide new services for the development of new industries and products. Third, the “Twelfth Five-Year Plan†places special emphasis on the development of strategic emerging industries. New opportunities.
Countermeasure 2: We must meet new challenges. During the "12th Five-Year Plan" period or even longer period, our country is ushering in an era of high costs, one is the high cost of land; the second is the high cost of housing; the third is the high cost of raw materials; the fourth It is a high cost of energy; the fifth is a high cost of environmental protection; the sixth is a high cost of talent; the seventh is a high cost of labor; the eighth is a high cost of capital; the ninth is a rise in the high cost of intellectual property; , high transaction costs. We face the enormous challenge of such a high-cost era in the future.
Countermeasures 3: To identify new positions, identify target customers, design our new products and services according to the needs of the target, and find new profit models and marketing channels.
Countermeasure 4: To develop new industries with development potential, the first is the new energy industry, the second is the energy conservation and environmental protection industry, the third is the new generation IT industry, the fourth is the green manufacturing industry, and the fifth is Cultural and creative industries, modern media industry, education and training industry, the sixth is the biomedical healthcare industry, and the seventh is the financial service industry and other production services.
Countermeasure 5: Look for our new competitiveness. We develop a green, low-carbon economy, a green economy, or a low-carbon development. This concept is not only a problem of three lows, but also has a high, that is, high efficiency and high efficiency. High efficiency and high efficiency come from many aspects of technological progress. So to find this new kind of competitiveness, it is not just about reducing carbon dioxide.
Countermeasures 6: Open up new markets.
Countermeasures 7: To shape a new brand, the most important new brand is that we must adapt to the requirements of low-carbon, green, energy-saving and emission-reduction. We must establish our own unique brand in this regard and assume our unique social responsibility.
Countermeasure VIII: Explore new mechanisms.
Li Bingren, chief economist of the Ministry of Housing and Urban-Rural Development and executive deputy director of the Science and Technology Commission:
Promoting building energy conservation and emission reduction is our historical responsibility to develop low-carbon buildings. At this stage, we also consider the issue of building energy conservation. Building energy efficiency is an important part of the country’s overall goal of energy conservation and emission reduction. Building energy consumption generally accounts for China’s About 30% of energy consumption, if calculated according to our total social energy consumption of 3.066 billion tons of standard coal in 2009, the building energy consumption is 920 million tons of standard coal, and the new building area will continue to increase in the future. The huge energy consumption is directly related to Energy security. We have done a lot of effective work in building energy efficiency, and we have achieved positive results. In terms of formulating energy saving laws and standards and formulating policies, we have awareness issues and technical problems in the research and development of building energy conservation technology products. There are also problems with management. We are actively adopting various measures to solve the problem as soon as possible, and we will make greater progress in promoting building energy efficiency.
According to the historical stages of China's urban development and urbanization and the actual situation of building energy conservation, we have identified the key areas for building energy conservation, mainly the reconstruction of urban heating measurement in the northern region, the implementation of new building energy efficiency standards, large-scale public buildings The energy-saving transformation, the promotion of residential decoration and assembly construction, the application of renewable energy in buildings, the demonstration of green buildings, etc. I sincerely hope that people of insight who pay attention to building energy conservation and energy conservation and emission reduction in China will work together to strengthen cooperation and assume our historical responsibility.
Xiu Long, President of China Institute of Architectural Design:
The use of planning and design to guide the construction of low-carbon cities is a complex and large organic system. The construction of low-carbon cities is to reduce the carbon emissions of the entire organic system, including reducing emissions and increasing carbon sequestration, and therefore requires a thorough organic The overall coordination plan includes not only the planning and design of urban construction, but also the urban low-carbon economic development plan and comprehensive evaluation index system for low-carbon urban construction. The construction of low-carbon cities is not a label. It also means not only high costs and high technology, but also people-oriented, local conditions and scientific implementation. Therefore, planning and design are very important.
The planning and design of low-carbon cities shall be implemented first. First, the significance and role of planning and design in energy conservation and emission reduction and low-carbon urban construction shall be fully understood. In the initial stage of implementation of the national energy conservation and emission reduction strategy, the focus of the government shall be mainly on front-end scientific research and At the end of the two stages of emissions, practice has proved to achieve certain results, but with the deepening of the national energy-saving emission reduction strategy, we found that a very important link has not been fully and adequately valued, making the effect of energy-saving emission reduction It is design and planning. My personal experience is very deep. It may be appreciated by all of you present here. The state has a lot of momentum and a great momentum in the atmosphere. Then the research institutes also follow up with A lot of this new technology and new products, at the end of the final results, our products are constantly emerging, including our development companies are constantly implementing, but all these are actually the most important part of this Not being fully valued, that is, how effective it is, how it can be implemented, and how can Application materials are in place, is designed to link, we should say in running the whole of the previous stage which did not get enough attention and reflect. Therefore, it also made us lose the results of energy conservation and emission reduction.
Planning and design is a particularly important intermediate link for translating scientific research results into practical applications. Planning and design are the batons of urban control, the soul of engineering construction, and the bridges and ties that transform advanced scientific and technological achievements into practical productivity. The key to optimizing utility functions and reducing project cost is to control the energy consumption of buildings and reduce carbon emissions from the source. It has an irreplaceable role. Planning and design have important guiding significance for achieving low-carbon emission reduction, building a resource-saving and environment-friendly society, and promoting sustainable economic development. Planning and design will play a role in building energy-saving emission reduction and low-carbon cities. Radiation effect from line to surface. The competent government departments at all levels should fully recognize the importance of planning and design for the construction of low-carbon cities. We must use planning and design as the starting point and carry out targeted efforts to promote energy conservation and emission reduction.
