The so-called change means that the existing pattern will be broken, a new pattern will be formed, and the distribution of interests will be repositioned. The movement of change since ancient times has been a tortuous process of new things replacing old things. Why do we have to rise to the challenge? Because this is the mission entrusted to us by history. To this end, you may wish to come with me first to review a set of familiar and frightening data.
According to statistics, China's annual standby waste of electricity only office computers and printers reached 1.2 billion degrees, equivalent to nearly 800 million yuan;
China's household standby energy consumption accounted for 10% of the family power consumption, the total annual amount of 36 billion degrees, an average of more than 60 yuan per person per year of needless expenditure;
In 2004, the Beijing government agencies per capita annual power consumption was 9,402 kilowatt-hours, equivalent to 19 times the 488 kilowatt-hours per capita of Beijing residents;
Because of the inefficiency of electricity, China's one-year waste of electricity is equivalent to the total amount of electricity generated by 2.3 Three Gorges power stations, which exceeds 80 billion yuan.
The leakage rate of China's urban water supply network reaches 20% to 30%, and the annual loss of tap water reaches 10 billion cubic meters, which is larger than the annual water transfer of the first phase of the South-to-North Water Diversion Project, which is costing a huge amount of money;
According to the data released by the United Nations Environment Programme (UNEP) survey, the economic loss due to the destruction of the environment has reached 6.6 trillion U.S. dollars in 2008, which is equivalent to 11% of the total global GDP. 11% of the total GDP. At this rate, the loss in 2050 will be more than three times than in 2008, reaching 28.6 trillion dollars. And that figure for our country is already more than $260 million, or as much as 10 percent of GDP.
"Neglect of environmental countermeasures will become a major danger to the world economy and the survival and development of mankind," which has aroused a high degree of concern in the international and domestic community. 1997 Kyoto Protocol was signed, marking the significance of the whole of humanity to "stabilize greenhouse gas content in the atmosphere at an appropriate level, thereby preventing the drastic increase in emissions of greenhouse gases. The signing of the Kyoto Protocol in 1997 marked the beginning of a consensus among all mankind on the goal of "stabilizing greenhouse gas concentrations in the atmosphere at an appropriate level, thereby preventing drastic climate change from harming humankind", and the 2009 Copenhagen Climate Change Conference has been described as "the last chance to save humankind".
Scientists predict that to prevent the global average temperature from rising by another 2 degrees Celsius, the world will need to reduce greenhouse gas emissions by 80 percent of 1990 levels by 2050. Reducing resource consumption and lowering greenhouse gas emissions is the responsibility of all mankind***. Therefore, in December 2009, China set the goal of reducing carbon dioxide emissions per unit of GDP by 40%-45% by 2020 compared with 2005 as a binding indicator to be included in the medium- and long-term planning for national economic and social development, and to develop corresponding domestic statistics, monitoring and assessment methods.
In order to promote the realization of these goals, China has formulated a national program to address climate change from the perspective of national conditions and reality, actively promoted economic and industrial restructuring, optimized the energy structure, and implemented policies and measures to encourage energy conservation and improve energy efficiency, and, on this basis, carried out the target assessment and one-vote veto system. Since 2005, the State has promulgated and implemented the Energy Conservation Law, the Circular Economy Promotion Law, the Measures for the Administration of Environmental Monitoring, the Energy Conservation and Emission Reduction National Action Implementation Program, and more than a hundred other policies and regulations, and the State's investment has exceeded trillions of billions of dollars.
But despite this, our energy saving and emission reduction work is still facing major problems and a huge test, in summary, at least the following aspects:
1, the lack of means, supervision is not in place.
Because of the lack of effective management tools, China's current energy consumption is still a rough management mode, but also stays in the data control and target supervision level. Although we know the overall consumption of how much energy, and even analyze the development trend of these data, energy-saving task is completed, but as for the use of these energy is reasonable, whether there is waste, waste of how much, due to the wide range of issues involved in the large-scale, in the past under the conditions of human and material resources and technology is simply can not be achieved.
2, sudden shutdown, rebound serious.
In order to "Eleventh Five-Year" energy saving and emission reduction targets reached, many places are engaged in mandatory shutdown and other surprise actions, this short behavior is not only not conducive to energy saving and emission reduction of sustainable development, but also to make people's legitimate rights and interests are damaged, resulting in new social conflicts. Last winter, some places in the long heating interruptions caused by the people's life is the best example. According to statistics, this year, China's energy consumption per unit of GDP has rebounded strongly. At this rate, our energy saving and emission reduction work will face a more severe test.
3, the awareness is not strong , huge waste.
Relatively speaking, China's public awareness of energy saving has to be strengthened, especially with the increase in income and living standards, energy expenditure accounted for the proportion of household expenditure gradually reduced, making it easier to ignore the waste of energy, it is difficult to form a sustained and stable energy-saving habits, resulting in a huge waste of energy. How can people's energy-saving habits have been completely changed, the best way is to carry out effective supervision, rewards and penalties are clearly defined, so that the energy-saving benefits and personal interests are closely linked.
4, the system is incomplete, difficult to implement.
Because of the lack of means, the basic data is not clear, the use of energy can not be refined management, not to mention the establishment of a relevant and effective system and indicator management. To implement the target management, system management, the first condition is the effective utilization of energy to carry out a scientific and detailed analysis, so as to accurately derive what is effectively utilized, which is wasted, so as to be able to target and stop waste.
Thus, we must change the concept, combined with the global digitalization development trend, innovative mode, completely subvert the existing management mode, realize the real meaning of "management energy saving", improve the effective utilization of energy, ensure the efficiency of investment, and promote the energy saving and emission reduction sustainable development.
Based on the development trend of the global digital city and the requirement of accelerating the development of the information industry, our company has successfully developed the "Two Campus Digital Comprehensive Information Management Platform" through four years of hard work and breakthroughs in a number of technical difficulties on the basis of the existing sensing and Internet of Things (IoT) technologies, realizing a real-time, chemical and environmental management of energy and environment in colleges and universities. It realizes the real-time, digital, visualization and refinement of energy and environment management in universities. Its sub-platform "Digital Energy Conservation Supervision Platform for Resource-saving Campus" has been put into use in Changsha Civil Affairs Vocational and Technical College, Changsha University of Science and Technology, Huaihua College, Changsha University of Health Science and Technology, Hunan Judicial Police College and other colleges and universities, and the effect is remarkable.
For example, in Changsha Civil Affairs Vocational and Technical College, we have helped the college to set up sub-systems such as electricity metering and energy-saving supervisory system, electricity prepaid management system, environment monitoring and split air-conditioning management system, energy data filing management system, energy audit and assessment management system, etc. We have installed nearly 5000 telemeters to realize round-the-clock monitoring of electricity consumption in all buildings, some offices, student dormitories, family areas, and other areas, and we are also able to monitor the energy consumption of students and their families. offices, as well as student dormitories, family areas, commercial stores monitoring to the home.
Through the application of electric energy metering and energy-saving supervision system, the power consumption of all monitoring areas can be viewed remotely and in real time, how much electricity is used in each building and office every day, when it is consumed, whether there is any standby power wasted, and if there is, how much is it, and who wasted it, and so on, all these, it is clear at a glance, it's clear, and the administrator can also send out the power consumption index through the system to execute the School-wide power use indicators, target management; if who is wasting power, who is over the target energy use, the system will automatically alert the waste and over the standard behavior to stop. At the same time, the system can also carry out scientific analysis of power balance, previously difficult to detect the phenomenon of electricity theft, leakage, now become simple and easy for managers to deal with in a timely manner.
Environmental monitoring and split air-conditioning management system application, managers can always grasp the air-conditioning operation, determine whether the air-conditioning is on reasonable, if not reasonable, the system will automatically send warning messages to the manager or user, the energy waste behavior immediately stop, saving electricity.
The hospital's student dormitories, family areas and commercial stores have all realized prepaid management to avoid overdraft of electric energy, and set up the vicious load recognition function in student dormitories, which can effectively control the use of dangerous electrical appliances such as heaters and electric ovens by students, and to a large extent improve the safety of electricity consumption by teachers and students.
Through the application of the energy data reporting management system, managers can enter or batch import the hand-written data of IC card meters and mechanical meters that are not included in the platform's unified monitoring and management into the system, and then analyze them statistically and unify the management together with the data automatically collected by the system.
In addition to the above functions, the platform can also carry out scientific power balance analysis, which is convenient for managers to deal with the phenomenon of power theft and leakage in a timely manner; the system can also be set up flexibly to automatically generate all kinds of graphic reports, which is convenient for managers to analyze statistically and all the data can be permanently preserved without affecting the processing speed of the system.
Through the application of the energy audit and assessment management system, the institute can carry out self-assessment of its energy-saving work according to the assessment system of the Ministry of Housing and Construction and the Ministry of Education for the construction of resource-saving campuses, so as to find out the weaknesses of the institute's work in the construction of resource-saving campuses, and to provide decision-making basis for the decision-makers, and to strengthen the work in the future, in order to achieve the purpose of successfully passing the assessment of the higher level.
Another example is the application of Huaihua College, which has not only constructed a monitoring system for electrical energy, but also a monitoring system for water supply pipeline network, which can view the operation status of water supply pipeline network in real time, and realize the real-time analysis of water balance, and discover various kinds of "running", "risk" and "dripping" in time. ", "drip", "leakage" phenomenon, it is convenient for managers to deal with in a timely manner to avoid more waste of water resources.
While our platform system is currently mainly used in colleges and universities, we are in the early stages of development and design, we have fully considered the institutions, enterprises, hospitals, parks, cities and towns, communities, large public **** building, families and other places of application, but also according to the customer's needs for personalized design.
For example, in the application of government agencies, we will incorporate the refined management of public vehicles, the vehicle's purchase age, use of departments, brands, insurance, purchase price, maintenance and repair, fuel consumption, mileage, average fuel consumption, real-time location and other data at a glance, so that managers can easily and conveniently grasp all the status of the vehicle's operation, to ensure that the effective use of national resources for the establishment of a two-type organs Provides a reliable management tool.
For example, in the application of hospitals, we will include medical supplies, waste disposal, medical equipment operation, air quality monitoring, etc., not only to achieve savings, but also to pay more attention to environmental protection, for the establishment of the two hospitals to provide a reliable means of management;
For example, the application of the park, the park can be all the enterprises of the energy consumption, waste residue, waste water emissions, air pollution, noise pollution and so on into the same platform to carry out, noise pollution, etc. into the same platform for real-time monitoring and management, to achieve the purpose of overall control, scientific audit and evaluation at any time, providing a reliable management tool for the establishment of the two types of parks;
For example, in the application of the town, we can include all large-scale buildings, institutions, enterprises, communities, streets, parks, etc., energy consumption and environmental monitoring into a platform for unified management, providing a reliable management tool for the establishment of the two types of cities and towns;
For example, in the application of community, street light control, vehicle parking, environmental monitoring and property repair are integrated into a unified platform management, providing a reliable management tool for the establishment of a two-type community;
For example, in the application of hotels, the system can monitor and measure the electricity consumption of each guest room in real time, which is not only able to calculate the amount of water and electricity consumed during the period of guests' check-in and check-out, but also able to calculate the amount of water and electricity consumed during the period of guests' check-out and check-out. Not only can it easily and quickly calculate the amount of water and electricity consumed during the period from the guest's check-in to check-out, but it can also be managed in a unified manner with the guest's other check-in information and be settled by itemized billing, which provides a reliable management tool for the establishment of a two-type hotel.
Practice has proved that, through the construction of "energy-saving supervision platform", the implementation of management of energy saving, can tap into the huge energy-saving space, can produce huge economic and social benefits. For example, Changsha Civil Affairs Vocational and Technical College, we can completely on the existing basis for the school to reduce energy consumption by more than 20%, although the school is constantly developing and expanding, but with the teachers and students and staff and energy-using equipment continue to increase, but we will eventually find that the hospital's energy consumption will not rise rather than fall.
At the same time, we have also made predictions for Central South University, which is currently consuming more than 80 million yuan of energy annually, and if the platform is applied and managed through the system, it is absolutely not a problem to save 15 million per year on the existing basis. By analogy, we can save at least 150 to 200 million yuan for the province's colleges and universities every year, and the return on investment will be more than five times. As for the country, according to the annual savings of 550 million tons of standard coal, each ton of 900 yuan accounting base on the savings of 50% accounting, through the application of the platform and energy-saving management, the annual savings of at least 240 billion yuan. Such a huge benefit, fully highlights the significance of our research.
