On September 1st, the author learned from the Municipal Management Office of the Municipal Urban Management Bureau that the Ningbo Jiangbei New City Road Lighting Contract Energy Management Project has been successfully completed. Since the project started in September 2013, the urban management municipal department has taken the North Outer Ring of Jiangbei New City. The north of the 329 National Road, the 5083 street lamp with a built-in period of more than 5 years, was led to the LED energy-saving technical transformation. At present, the project is in the testing stage of the effects of illumination, energy saving, etc. It is expected that the energy saving rate of the renovated lighting facilities can reach 40%.
According to the relevant person in charge of the Municipal Urban Management Bureau, in 2009, the “Ten Cities and Ten Thousand” semiconductor lighting application project pilot project initiated by the Ministry of Science and Technology of the People's Republic of China was listed as one of the 21 pilot cities. Under this opportunity, the urban management department Committed to the promotion of LED products in various lighting areas such as residential areas, roads and public landscapes.
The Jiangbei New City Road Lights Reconstruction Project adopts the “zero-input” and “zero-risk” contract energy management (emc) model, which not only exempts the government from capital and technology risks, but also fully releases the production capacity of led enterprises and promotes The development of the LED industry in Ningbo is a relatively new energy-saving retrofit model for street lamps in China.
It is understood that this transformation has many bright spots, such as in the contract energy management (emc) mode, participating in the company's self-financing, self-solving machinery and staffing, providing quality services throughout the process. Not only must the energy condition diagnosis and energy-saving project design be completed, but also the energy-saving technical transformation of the high-consumption and low-efficiency lighting facilities within the project scope. In addition, it is also necessary to undertake the maintenance and maintenance of lighting facilities during the six-year contract period.
At the expiration of the contract period, if the tested project facilities are in good condition and the road lighting quality reaches 85% of the national standard, the urban management department will take over or continue to entrust the participating enterprises to undertake the normal maintenance work of the facility. During the operation of the project, all the funds required for the participating enterprises to purchase equipment materials, installation, commissioning and maintenance are all derived from the energy-saving benefits of the six-year contract period, and the government departments do not need to bear any capital investment and technical risks.
The implementation of the LED transformation of the 5083 street lamp not only reduced the original power of the street lamp, but also installed an automatic dimming device on the street lamp to further save energy by reducing the light in the middle of the night. It is estimated that the annual electricity consumption will be 2.85 million kWh, and the electricity cost will be 2.6 million yuan, which is equivalent to saving 1,026 tons of standard coal, 2,667 tons of carbon dioxide emissions and 24.6 tons of sulfur dioxide emissions. It can also reduce the mercury in the traditional energy-saving lamps and sodium lamps. Pollution.
The benefits of energy saving and environmental protection have been realized. What is the level of lighting quality of the project? It is understood that the initial average illuminance of the retrofitted street lamps has not decreased, but has exceeded 15% (including 15%) of the design standard. It will also reach 0.5 or above, providing a safe and comfortable urban light environment for citizens to travel at night.
The relevant person in charge of the urban management department also said that the successful completion of the project not only means that the green energy-saving level of Ningbo city lighting is constantly improving, but also marks that the pace of market-oriented maintenance of lighting facilities in the city is accelerating, and the lighting effect is “people-oriented”. The pursuit of "continuous improvement."
The management concept of urban lighting no longer stays on the "lighting" of lighting and lighting, more is to pursue the improvement of lighting quality, through the overall planning of urban light environment and refinement of color temperature, illumination, uniformity, etc. The improvement of indicators will integrate more human elements into the standard of “lightening”. For example, the color temperature is controlled to about 4700k to achieve a warm white light effect, giving a comfortable visual experience; improving the illumination and uniformity level of road lighting, bringing a stable and just-right visual environment to the citizens, especially the majority of owners, avoiding illumination. Negative effects caused by unevenness, too dark or even too bright. The requirements of urban lighting have been upgraded from standardization to scientific, humanized and artistic, fully embodying the "people-oriented" lighting management concept.
In the interview, the author learned that the urban management department will also carry out the special activity of “lighting the people to go home” to solve the problem of maintenance difficulties in the lighting facilities of the road community and “tree block lights”. The Sanjiang River and the Sixth Bank along the Yangtze River landscape lighting upgrade project is also about to start at the end of the year, the lighting equipment will all use led lamps, while bringing beautiful night scenes for Ningbo, it also has the effect of ecological energy-saving operation.
