In other words, we promote energy conservation and emission reduction, and the contribution rate of energy conservation in our buildings is 20%. We mainly realize1.200 million tons of standard coal through the four links just mentioned. First of all, how to control the increment problem and how to strictly implement the energy-saving design standards for new buildings, so as to realize the energy-saving of 70 million tons of standard coal. The second is the supervision of large buildings. The third is to promote the energy-saving transformation of existing residential buildings in the northern region, with an energy saving of190,000 tons. Third, we are promoting the use of renewable energy and achieving energy-saving goals through green lighting. From the five tasks, we consider the first one. We mainly pay attention to five aspects of energy saving in new buildings. First of all, all new buildings must strictly implement energy-saving renovation standards. Second, we have implemented the standard of 65% energy saving in four municipalities and mature areas. We have reached this standard in two municipalities directly under the central government, and it is being carried out in Beijing and Tianjin. In the other two municipalities directly under the central government, we will strictly implement the local energy-saving standard of 65% next year and the year after.
During the "Twelfth Five-Year Plan" period, we will realize the transformation from 50% energy saving to 65% energy saving. The third is the demonstration of low energy consumption and green building that we are doing. Our Ministry of Construction has issued a notice asking all developers to demonstrate enthusiastically. By the end of last month, the effect of this piece was not very satisfactory. Several provinces have not reported yet, and even fewer projects have been reported. Here, I will say a question that may have to cause us to think deeply. I have been pushing this job for several years, but I found a problem. What problem? Is that developers are not very enthusiastic. There are several reasons for this. On the one hand, our information asymmetry, that is, the content we should publicize is not in place. From the government's point of view, this may be our responsibility. In the second aspect, there are still some problems for developers to understand this problem. What's the problem? We also hope that through such a seminar, we can discuss with you what the problem is.
The fourth thing, how to guide the development of energy-saving building materials, in this piece, we focus on the following points. First of all, how to guide the use of high-type concrete and high-strength steel. Second, how to guide the development of energy-saving wall materials and windows. At present, it should be said that materials and products that meet the requirements and standards are still in short supply in our business. This is a special phenomenon in China today. At present, China has excess capacity, but it still lacks strong materials and building materials that meet the requirements of energy conservation and environmental protection. Last year, China Academy of Sciences measured 2 million square meters of buildings built according to 50% building energy efficiency standards. What does the measurement result show? It shows that the building we do according to 50% energy saving actually has only 30% energy saving effect. Why? There may be three main reasons. One is the problem of construction. The second is the problem of our operation and management. The third problem includes cutting corners and not meeting the requirements.
From these cases, we can see that there is indeed a big gap between materials and products. From another aspect, it also shows that the development prospect of our residential industry is still great.
The fifth question is how to change from simply promoting building energy conservation to promoting four festivals and one environmental protection during the Twelfth Five-Year Plan period, and finally realize the strategic requirement of developing energy-saving and land-saving buildings put forward by the State Council of the CPC Central Committee.
The second is to establish an energy-saving supervision system for government office buildings and large public buildings. Here is a background for everyone. When we were studying building energy consumption, we found a problem. In residential buildings and public buildings, the prominent problem is large-scale public buildings, which is very prominent. There is a set of data. At present, large-scale public buildings, that is, buildings with an area of over 20,000 square meters, account for only 4% of the total energy consumption, but their energy consumption accounts for 22% of the total energy consumption of buildings, that is to say, it is five times the energy consumption per unit area of ordinary buildings or residential buildings, and our actual measurement is 5- 10 times. This is a problem.
The second question is that the government office building is special and is used by the government itself. The government calls for promoting energy conservation and emission reduction, and should take the lead in setting an example. So, we put all the government office buildings together. Therefore, we put forward a groundbreaking system internationally. What system? It is a national energy-saving supervision system for government office buildings and large public buildings. This system is the first in the world, and our system generally has the following main contents:
One content is that new government office buildings and large public buildings need corresponding management systems and their rigid management from planning to design to completion acceptance. What is the primary purpose of existing government office buildings and large public buildings? It is to establish a supervision system for it and let it run in an energy-saving way. This is the second rule. Third, on this basis, we have cultivated an energy-saving service system. Because through the establishment of supervision, we can turn the energy-saving potential of life into the realistic energy-saving demand. We have now introduced a discount policy, on the one hand, strengthening supervision, on the other hand, discount interest, carrots and sticks. Through the discount policy, we can guide the energy-saving transformation of high-energy-consuming office buildings and large-scale public buildings, which can also cultivate a new market, that is, the building energy-saving service market, which also brings many related additional effects, which can improve employment, and so on.
Third, the heating system transformation and energy-saving transformation of existing buildings in the northern region. Here, I will give you a brief report. We used to ask existing shopkeepers to renovate. Now we reposition it in the energy-saving transformation of existing residential buildings in the north. For the northern region, generally speaking, 80% of the northern region does not meet the building energy-saving design standards. Secondly, these buildings do not meet the design standards of building energy efficiency, so we call them high-energy buildings. A heating period may be 2-3 times higher than that of buildings at the same latitude in developed countries. Third, although we consume a lot of energy, the thermal comfort of residents is not high. We did some renovations in Tangshan. Before the renovation, the indoor temperature was 16 degrees, which was lower than the national heating requirement of 18 degrees, which means that the thermal comfort of his house is still relatively poor. On the one hand, the energy consumption is high, but the thermal comfort is still low. Third, the average person's calorie expenditure is still high. This is one aspect.
The second aspect is not to mention the energy-saving transformation of buildings in transitional areas or the south, which is also based on the results of our research and practice. In Changsha, we design houses according to 50% energy-saving standards. What is its theoretical energy consumption? Generally speaking, it should be 50 degrees in summer, but the result of measurement is that the current consumption is less than 30 degrees, with an average of about 20 degrees. In other words, the house designed according to the energy-saving standard should use 50 degrees of electricity to achieve 50% energy-saving rate, but the actual results are only 20 degrees and 30 degrees. What is the reason? Because 50% of energy saving is the energy saving rate calculated under a certain comfort level, because people in transitional areas and the south are not too keen on thermal comfort, that is, they would rather sacrifice thermal comfort, so their actual energy consumption has not reached the specified energy consumption level. Therefore, we will not force the renovation of existing buildings in the southern and transitional areas from the central government level. Pay attention to the northern region.
In the northern region, there are two main tasks. One task is the reform of heating system, how to transform the current welfare heating into commercial heating. Second, how to improve the formation mechanism of heat price and the system of charging according to heat consumption. Third, how to promote the corresponding measurement reform of heating charge system. Fourth, at the same time, improve the social security system of low-income people, so that they can get the protection of heating. Finally, how to sort out the competition mechanism, realize effective competition in the field of heating, and improve management efficiency and service level. Five major tasks. One more thing, we are promoting the large-scale application of renewable energy in buildings. Promoting the large-scale application of renewable energy in buildings began last year. The Renewable Energy Law came into effect on 1 month 1 day last year, stipulating that the state should set up special funds for the application of renewable energy. According to the requirements of this law, the Ministry of Finance and the Ministry of Construction set up a special fund for the application of renewable energy, one of which is dedicated to promoting the large-scale application of renewable energy in China.
Besides, on the one hand, China has strict constraints on our energy and resources. For example, our energy conditions are very poor, but on the other hand, China is rich in renewable energy. So after analyzing these, we have determined a basic strategic orientation. First, take the utilization of renewable energy in buildings as a starting point to guide the adjustment and transformation of China's building energy structure. The growth mode of building energy consumption in China. Where do we start? At present, we are faced with many risks and problems. One is the promotion mode, the other is the system construction, the third is the standard, and the fourth is the product material. To this end, we have determined a basic path, starting from the municipal demonstration, groping for experience, summing up the model, forming standards, forming a promotion mechanism, and comprehensively pushing it out during the Twelfth Five-Year Plan period. This is the general idea. At present, according to this idea, three batches of renewable energy have been used in buildings on a large scale. In 2007, the first batch of demonstration projects were implemented in Beijing, Inner Mongolia, Shandong, Guangdong and Shenzhen provinces. The second batch has been issued and will be demonstrated in more than 20 provinces and cities across the country. Now the third batch is launched.
What I want to say here is that, in fact, the three batches of projects we declared were worse than our expected results, such as the third batch. How much did we finally declare? In 234 provinces, you should also pay attention to the State Council's energy conservation and emission reduction work plan this year, that is, document Guofa 15 clearly stipulates that 200 demonstration projects of large-scale application of renewable energy in buildings should be carried out. However, only 234 items have been reported. You don't know this information? I don't think so. Since last year, our first and second projects have been gradually rolled out. Why don't you report enthusiastically and explore the demonstration application of renewable energy in buildings? There are some problems in this, and I also want to stay in this meeting and discuss them together.
The fifth item is green lighting. We want to start next year. In our country, first, roads, second, communities and third, houses. Through these three aspects, as soon as we establish standards. Second, promote energy-saving lamps. Third, first gradually explore the experience, and then promote it. This work will begin next year. After reporting the five tasks, I will report to you what measures we have taken to promote these tasks. Mainly three, one is through institutional innovation, the other is through policy guidance and encouragement, and the third is through technological progress. First of all, from the perspective of system and mechanism, from the perspective of national system, how can we gradually realize such a transformation from the current push of production to the pull of demand? Let me give you an example here. Since the early 1990s, wall materials and wall reform have been pushed to the present, and 15 years has passed, so it should be said that considerable or remarkable achievements have been made. That is to say, the utilization rate of our emerging wall materials has reached 40%-50%, with remarkable results, but if we look at the progress of 15, I think it is obviously slow. Why slow? One of the main reasons lies in our concern. In the past, we mainly promoted it from the production side. We can analyze who we encourage economically. We encourage manufacturers, and I also encourage those who produce this material. So far, as we all know, we are implementing the policy of discount interest and wall reform fund in this link, but what we really care about is the manufacturers.
Can you change your mind and pull from the demand side in another way? The demand side pulls several links, can a management system be changed? From the current production department to the construction department, it is from the management of use. Second, can the incentive policy be aimed at developers or even directly at property buyers, so as to be more in line with the laws of the market economy? This is one aspect.
The second aspect is the establishment of institutional innovation. There are several institutional innovations. First, should we set up an evaluation system for a series of tasks? Here, I want to say that our party group of the Ministry of Construction is very concerned about this work. Since 2004, we have carried out special evaluation and appraisal of building energy efficiency every year. To tell the truth, among so many people in charge of energy conservation, I think the Ministry of Construction has been established. It can be seen that since 2005, informed criticism praised those who did well and informed criticism did poorly. In 2006, as in 2006, whoever does well will be praised and whoever does badly will be criticized. Here, I want to report to you that we have made great determination to carry out informed criticism for the construction departments of various provinces and cities. Because we have to rely on them to do our work, but we are criticized for not doing well. This is a relative failure. Some people have done a lot of work, but the promotion effect is poor, so they are criticized.
I think it's really not easy to build up such great determination from subordinates. The effect of our special inspection is showing. For example, let me give you an example. In 2005, we conducted a special survey. How is the implementation? 50% of the energy-saving design standards are implemented in the design stage, and only 22% are implemented in the construction stage. In 2006, this figure became 94% in the design stage and 52% in the construction stage. One year's work has improved so fast that the inspection has not come out this year, but the preliminary information we have, because the design stage and implementation stage are the key, is the construction stage, which should be above 80% this year. So I think our current system and mechanism are still effective.
In the other part, I will focus on introducing to you what systems we have established in terms of institutional innovation. One * * * seven systems, the first new construction market access system. Second, the energy efficiency labeling system of buildings. Third, the old building energy-saving transformation system. Fourthly, the management system of building energy consumption system. Fifth, large-scale building energy management system. Sixth, statistical system of building energy consumption. Seventh, the technical data promotion system. The first system is the market access system of new construction characterized by administrative license. This was written in the State Council's decision to further strengthen energy conservation. What are the characteristics of this market access? 1. Make full use of the existing administrative license, and no new administrative license will be added. Second, according to the requirements of the Administrative Licensing Law, the licensing conditions are added on the basis of the existing administrative licensing, and the implementation of building energy efficiency standards in planning, design and construction is regarded as the licensing conditions. Before issuing planning research regulations and issuing planning permits, the planning permission department shall solicit the opinions of the competent construction department on whether the project meets the requirements of the building energy-saving design department, and the competent construction department shall give a reply on whether to approve it within 10 days. What is the basis? That is, have you implemented the building energy-saving design standards? This is a ... Secondly, we use the construction permit, and we will conduct special inspections on the implementation of building energy-saving design standards in the construction design stage. If it is realized, it will be sent. If you can't reach it, you should refuse. The construction permit must be checked at the construction stage to see whether it meets the energy-saving design standards, and the construction permit shall not be issued if it does not meet the requirements. This is the second one.
For the third completion acceptance, we issued a new acceptance specification. Whether and how you do it according to the building energy efficiency standards during the construction stage has become a necessary condition for the completion acceptance and filing. This is the first system I reported to you.
The second system, building energy efficiency labeling system. We divide buildings into the following categories: one is compulsory and the other is voluntary. There are several examples of coercion. The first developer developed a large number of houses. In this case, the principle of self-identity is adopted. When each developer sells a house, you must make your indicators clear, and you must record the energy-saving measures you have taken in the sales contract of your house and the responsibility guarantee of your house. After the recording, you have to take responsibility. What responsibility? Whether to plan, design and build according to energy-saving building standards is ultimately the responsibility of developers. This is a ... Second, for our large public buildings and government buildings, we adopt mandatory signs, which can only be marked after being evaluated by a third party. The second category is voluntary. In order to encourage developers to develop energy-saving and land-saving buildings, you did better than the national standard, and you applied for voluntary labeling. After you apply for logo, the third party will give you an evaluation, and we will give you an economic reward. If the final economic incentive policy is finalized, you must pass the appraisal and prove that it is superior to the national standard. This policy is being negotiated with the Ministry of Finance. I guess it's time for an introduction.
The third system is the energy-saving transformation of existing residential buildings. First of all, there is a basic positioning, and we position it as the responsibility of the government. Why is it the responsibility of the government? Because the energy-saving renovation of existing residential buildings is a job and a task undertaken by the government from a global perspective. In this field, simply speaking, the market mechanism is partially out of order. If you want to do it through market mechanism, there is no successful experience in the world. So, this is the basic positioning. What have you done for the government? First of all, you are responsible for investigating residential buildings. You should investigate clearly what the building structure and architectural form are in your area and find out your family background. Second, you should plan energy conservation and emission reduction on this basis, and at the same time, you should fully respect the wishes of property owners according to the property law. Only on this basis can you carry out energy-saving transformation. Energy-saving transformation is also organized and implemented by local governments. Finally, the question of acceptance evaluation. This system, with so many requirements, has been written into the building management regulations as a specific procedure. After the the State Council trial. Because of the time, I will simply say another one, which is the specific management system of construction land and the management system of large buildings. In this system, the key is five basic systems.
