If half of China's light bulbs are replaced by LEDs, the annual electricity consumption will be equivalent to the power generated by 2.5 Three Gorges power stations, which is close to 210 billion kWh. This means that 105 million tons of raw coal can be saved every year, and 14 million tons of waste gas and dust can be reduced. This is of great significance to China that pursues green development. In fact, LED is no stranger to the people. People use mobile phones, computers, digital cameras, and cars in their daily lives. In the urban landscape, instrumentation instructions, semiconductor lighting has been widely used. For example, the famous Shanghai Oriental Pearl TV Tower is decorated with night illumination in the night, using semiconductor lighting. However, the current LED penetration rate is still not high, and the biggest problem is cost.
Some people call it a long-life lamp, which means a lamp that never goes out. As a new type of semiconductor light source, its birth triggered the revolution of the fourth human lighting method. In some developed countries, LEDs for energy conservation and environmental protection have long been popular and have begun to be widely used. Along with the rise of China's low-carbon economy concept, China is the world's most populous country, and the government's use of LED light sources is also highly respected.
Since September 2012, the Provincial Department of Finance has promoted pilot projects for energy-saving renovation of LED lighting in Harbin University of Commerce, Harbin Normal University, and 11 top-three hospitals. After nearly two years of practice verification, the energy-saving and environmental protection effects exceeded expectations. It has also expanded its financial resources, reduced expenditures, and raised the environmental awareness of electricity-using units.
The pilot project of LED lighting renovation in Heilongjiang Province also triggered a series of thinking about LED intelligent lighting instead of traditional lighting.
The pilot led more than 50 companies to join the transformation into the library of Harbin University of Commerce, and the study room was really bright. Now, our classrooms, study rooms, and libraries are not only bright, but also have no previous flashes. The light source is very stable. The students of Ha Shangda University praised the learning environment after the renovation.
Not only is the student satisfied, the school is no longer distressed by the electricity bill. After the transformation of the library, the average illuminance increased by 257 while saving 63, which is equivalent to saving 90 under the same illumination; the self-study room increased the average illuminance by 227 while saving 58, which is equivalent to the same illumination to save electricity 87. School lighting points The longest area for the bright time is the library and the study room. These two areas open at 5 or 6 o'clock every morning and close at 10 o'clock in the evening. The lighting continues to light up for 16 to 17 hours. The library, The power saving effect after the renovation of the self-study room is extremely remarkable. The LED lighting renovation is very satisfactory to the school.
The lighting renovation of medical institutions has also achieved amazing power-saving effects. Statistics show that the total investment of 11 top three hospitals is 7.73 million yuan. The total power of traditional lighting before transformation is 2103 kilowatts, and the total power after transformation is 768 kilowatts. It is calculated by daily average lighting for 16 hours and average electricity cost of 0.936 yuan/kWh. The annual energy saving is 7.8 million kWh, the annual electricity saving and maintenance costs are 8.15 million yuan, and all investment can be recovered in one year. At the same time, the annual coal consumption is reduced by 2,652 tons. The carbon dioxide emissions are 6,123 tons and the sulfur dioxide emissions are reduced by 27 tons. The economic and environmental benefits are considerable. Once the province's medical system has been completely remodeled, the energy saving fee will be even more amazing! Relevant persons from the Provincial Department of Finance are full of confidence in this.
According to statistics, in 2013, the provincial government directly spent 510 million yuan on electricity consumption. After the full implementation of LED lighting renovation, the annual electricity cost could be saved by 116 million yuan, and the annual coal consumption could be reduced by 46,000 tons and carbon dioxide emissions could be reduced by 106,000 tons. From September to November 2012, the Provincial Department of Finance's LED lighting renovation of its own office building played a leading role in promoting energy conservation, emission reduction and environmental protection in Heilongjiang Province. Before the renovation, the office building of the hall used traditional lighting such as fluorescent lamps and energy-saving lamps with a total power of 159 kW. After the renovation, LED lighting fixtures were used, with a total power of 57 kW and a power saving rate of 64.2. The lighting was performed for 9 hours per day. The electricity consumption is 918 degrees, the daily electricity cost is 860 yuan, the annual saving is 276,000 kWh, and the annual electricity saving is 258,000 yuan. The reconstruction enterprise promises to guarantee the warranty for 3 years, and can save 7500 ç› traditional lighting fixtures in three years. The average life expectancy of traditional lamps is one year, and the total cost per lamp is 15 yuan. The savings for purchasing these lamps are 113,000 yuan, within three years. The total cost savings can be about 887,000 yuan. The power here does not talk about environmental and social benefits. In terms of reducing electricity expenses alone, hundreds of units in provincial departments can save hundreds of millions of yuan in one year. How many enterprises need to pay taxes? ! How many things can be done with hundreds of millions of dollars of funds! Relevant people from the Provincial Department of Finance lamented.
Since September 2012, the Provincial Department of Finance has started from the market development, and has initiated LED lighting energy-saving renovation experiments in the Provincial Finance Department, Harbin University of Commerce, Harbin Normal University and 12 top three hospitals.
Experts suggest that the experts in the development of the LED industry, the Provincial Science and Technology Commission, have calculated an account. According to the calculation of coal-to-electricity conversion rate, Heilongjiang Province replaces traditional lighting with LED lighting, which can reduce the annual standard coal for power generation by 2.19 million tons. It far exceeds the current annual emission reductions (1.69 million tons of standard coal) generated by the actual absorption of wind power in Heilongjiang Power Grid, and has made positive contributions to the completion of the province's emission reduction targets. Not only does it save a lot of electricity, but it also saves a lot of lighting costs. LED lighting replaces the traditional lighting power saving efficiency of 60, based on the 2013 province's lighting power consumption of 11 billion degrees based on the data, the province completed the LED lighting energy-saving transformation, can save 6.6 billion kWh per year, can save lighting costs of 5.7 billion yuan. It can be said that the province's LED lighting energy-saving transformation is the growth point of expanding the domestic demand consumer market. It is expected that through the LED lighting renovation, a new domestic demand consumer market with a scale of 50 billion yuan can be cultivated for Heilongjiang Province, and an annual output value can be hatched. A manufacturing entity with a scale of 50 to 10 billion yuan.
According to an interview with reporters, Zhang Zhongzhao, deputy head of the Electronic Information Expert Group of the Provincial Science and Technology Commission and the Director of the Communication Technology Institute of Harbin Institute of Technology, said: In the past four years, Heilongjiang Province has had a successful transformation practice and has a good start. Has gained a wealth of practical experience, has already had the basic conditions for comprehensive promotion in the province, if you further integrate the province's industrial resources, it will do better.
Experts believe that Heilongjiang Province should make full use of the idle factory buildings and infrastructure in industrial parks across the province in accordance with the idea of ​​revitalizing stocks, and plan according to the region. This will not only greatly shorten the investment and construction cycle, reduce investment risks, but also accelerate industrial construction. The progress, quickly occupy the lighting product market, grasp the market opportunities. In addition, Heilongjiang Province is far away from the developed coastal areas, and the construction and market development of emerging industries are relatively lagging behind. Therefore, in terms of LED lighting renovation, we still have the opportunity to play space difference and time difference, organize the province's resource development and control this development. Virgin!
In terms of government guidance, experts recommend the establishment of a government promotion agency. At present, energy conservation and emission reduction have certain non-market attributes, which require government guidance and management. It is recommended to set up a promotion agency to be responsible for formulating the five-year plan for LED lighting renovation in the province, and to issue binding and quantitative LED lighting energy-saving emission reduction targets. At the same time, it is responsible for raising special support funds for LED lighting renovation, and at the same time establishing a market operation mechanism, insisting on the implementation of LED lighting enterprises in the province, and implementing the contract energy management model with the support of the province's financial capital. It is recommended that the provincial government set up a special support fund for LED lighting energy-saving renovation, and tilt the annual energy-saving and emission-reducing funds of the provincial finance to the LED lighting energy-saving renovation project to improve the effectiveness of energy-saving and emission-reducing funds. Promote the interaction between banks and enterprises. It is recommended that financial institutions in the province carry out special projects for green finance, provide financial support for construction enterprises, achieve a win-win situation for both banks and enterprises, and ensure that funds and projects do not flow out.
Contract energy management mode involved in energy-saving renovation According to reports, the implementation of LED lighting renovation pilot units in Heilongjiang Province is a contract energy management model, that is: energy-saving service companies provide energy-saving renovation services based on energy-saving targets of energy-using units, and the cost of subsidies, energy-using units Paying for the cost of energy-saving renovation projects of energy-saving service companies with energy-saving benefits is a one-time investment, which achieves the goal of saving costs and saving costs. According to statistics, after the implementation of LED lighting renovation, Harbin University of Commerce can save electricity costs of 2.295 million yuan, save maintenance and replacement costs of 350,000 yuan, Harbin Normal University (Jiangbei Campus) can save electricity costs of 780,000 yuan, save maintenance and replacement, etc. The cost is 182,000 yuan, 11 of the top three hospitals can save electricity costs of 7.3 million yuan, save maintenance and replacement costs of 850,000 yuan, the provincial finance department can save electricity costs of 258,000 yuan, save maintenance and replacement costs of 38,000 yuan. At present, the provincial energy industry committee, the provincial development and reform commission, the provincial government agency (public part of the government building) LED lighting renovation energy-saving emission reduction effect is also very obvious.
In order to actively promote the LED lighting project transformation in Heilongjiang Province, a few days ago, the Provincial Department of Finance issued the Notice of the Provincial Department of Finance on Implementing the Budget Management Issues Concerning the Implementation of LED Lighting Reconstruction by Contract Energy Management, and Implementing Contract Energy Management Mode for Provincial Direct Units The lighting renovation introduced a support policy. In terms of budget preparation, energy-using units are encouraged to pay the energy-saving renovation project cost of energy-saving service companies with energy-saving benefits. Prior to this, the unit department budgeted public funds have arranged the office electricity budget, but it is not clear whether it can be used to pay for the transformation cost. It is clear that the energy-using unit adopts the contract energy management method to implement the LED lighting transformation, and the department budget office electricity fee quota remains unchanged. The post-saving electricity bill can be used to pay for the cost of the energy-saving retrofit project. In this way, it not only meets the service form of contract energy management mode in the budget of office electricity bills, but also encourages the unit to implement LED lighting renovation through contract energy management, thereby reducing investment in energy-saving renovation projects. In terms of payment management, in accordance with the relevant provisions of the national and provincial treasury centralized payment system, the method of payment for funds by energy-using units is regulated. In terms of asset management, in accordance with the Financial Regulations of Administrative Units and the Financial Regulations of Institutions, the asset management after energy-saving renovation of energy-using units is clarified. LED lighting equipment conforms to fixed assets refers to assets that have a service life of more than one year, a unit value of more than 1,000 yuan, and basically maintain the original material form during use. Although the unit value does not meet the prescribed standards, but a large number of similar materials with a durability of more than one year, as a provision for the management of fixed assets, the unit will count the LED lighting equipment into the unit fixed assets account according to the regular bills issued by the energy conservation service company.
It can be foreseen that with the vigorous promotion of the government and the shift of global industrial ladders, the future lighting will be the era of LED dancing.
Medical unit lighting renovation can be done first?
The experiment proves that after the implementation of LED lighting transformation, the average illumination of the pilot unit is increased by more than 20, and there is no flicker or glare in use. And with the introduction of national policies, the prospects for LED lighting renovation can be expected.
According to the data of Heilongjiang Province's final accounts, in 2013, the province's direct government spent 510 million yuan on electricity consumption, accounting for 35% of office electricity, and LED lighting and electricity saving 65. After comprehensive renovation, it can save electricity by 116 million yuan annually. The procurement and maintenance costs are 10.8 million yuan, and the annual coal consumption is reduced by 46,000 tons and the carbon dioxide emissions are reduced by 106,000 tons. The economic, environmental and social benefits are considerable.
According to the relevant person of the Provincial Department of Finance, during the energy-saving renovation, it was found that some units did not turn on the lights or even turned on the lights in order to reduce energy consumption. It was a misunderstanding and not desirable to simply achieve energy saving. There are many aspects of lighting energy conservation. Focusing on the application of light sources, lamps and accessories, it can bring a wide space for energy saving. From the perspective of lighting control, there are also many ways to achieve energy saving. For gas discharge lamps, when the motion detection control switch is adopted, the life of the light source is greatly affected by the number of switching times, and the switch is equivalent to lighting for several hours at a time, so it is necessary to find a better light source without being affected by the number of switching lights. LED is a good choice.
Professor Zhang Zhongzhao, director of the Harbin Institute of Technology, said that Heilongjiang Province has a good start to implement LED lighting renovation projects. It should firmly support its own industry to form an industrial chain. It is recommended to start the LED lighting renovation of provincial units as soon as possible. Experts suggest that the comprehensive transformation of medical units be put in the first place, and it is recommended to start the lighting renovation of township hospitals and county hospitals in the province. Township hospitals are financial support units, which are similar to the attributes of provincial organs. In the grassroots medical units, the promotion of lighting energy-saving renovation can play the role of promoting the above and below, and expanding the lighting energy-saving transformation work to the grassroots level for local governments.
