From this year onwards, all new urban lighting in Shenzhen will adopt high-efficiency energy-saving products, and all low-efficiency lighting products will be eliminated in public places before the end of the year to achieve the current state of urban lighting. Based on the electricity consumption in 2008, the annual energy saving will be 5%, 3 years. (2009-2011) The goal of saving 15% of electricity. This is what the reporter learned from the new government bulletin.
Elimination of inefficient lighting products in public places before the end of the year
In recent years, the city's urban lighting has developed rapidly, especially the amount of facilities managed by public institutions has increased a lot, and electricity consumption has grown rapidly. In 2007, the city's public institutions managed more than 400,000 urban lighting, and the electricity consumption was about 300 million kWh, which exceeded 0.5% of the total electricity consumption of the whole society. In order to implement the national energy conservation and emission reduction policies, promote green lighting, and build an ecological city, the city issued the “Opinions on Strengthening the Comprehensive Energy Saving Work of Urban Lighting in Shenzhen†and proposed eight major urban lighting energy saving measures.
One of the measures is to replace the street light fixture. Before the end of 2009, road lighting and public places will all eliminate inefficient lighting products such as incandescent lamps and mercury lamps. According to the road grade and site conditions, they will be replaced with high-efficiency lighting products such as high-pressure sodium lamps, ceramic metal halide lamps, fluorescent lamps, electrodeless lamps and LEDs. Reduce lighting power while ensuring lighting effects. The application rate of high-efficiency energy-saving lamps before the end of 2010 is more than 85%, the application rate of high-efficiency long-life light sources is over 85%, and the application rate of energy-saving ballasts is over 85%. According to the above objectives, the annual plan will be revised and replaced annually.
At the same time, the midnight lights are promoted on the roads with conditions, and the double-sided lighting roads with double-circuit power supply on each side are illuminated in the middle of the night. Carefully check the roads that have been implemented in the middle of the night to improve the lighting conditions and ensure the lighting effect.
Reduce landscape lighting time
According to the "Opinions", the city must control the lighting time of urban lighting. On the one hand, the construction of the "three remote" monitoring system for urban lighting, covering the city's street lights and the main landscape lighting, making the lights on and off more scientific and reasonable, and avoiding power waste. The “Three Remote†monitoring system will continue to be improved within the SAR to strengthen management. Bao'an District and Longgang District respectively established the “Three Remote†monitoring system, covering the central city in 2009 and covering the streets under its jurisdiction in 2011. Guangming New District and Pingshan New District established a sub-system based on the “Three Remote†monitoring system of the Municipal Lighting Environmental Management Center before the end of 2011. Before the end of 2011, the data of the “Three Remote†monitoring system of the city was collected in the monitoring room of the Municipal Lighting Environmental Management Center to implement the secondary control of urban lighting in the city.
On the other hand, it is necessary to reduce the lighting time of the landscape lighting. The landscape lighting will be illuminated as required. The city, district and street lighting scenic spots will be closed except Friday, Saturday, statutory holidays and major celebrations and important reception tasks.
The status quo proposed in the "Opinions" urban lighting energy-saving measures also include adjustment of street lamp power supply point distribution, installation of power saver at street lamp power supply point, installation of reactive power compensation equipment, promotion of dual-power ballasts, and strengthening of street lamp maintenance management.
Actively promote the application of LED street lights
In terms of energy saving in new urban lighting, the Opinions require the application of LED street lights in secondary trunk roads, branch roads, residential roads and other outdoor public places according to road types and actual conditions. It is also not suitable to use high-brightness and high-energy lamps such as powerful searchlights, high-power floodlights, large-area neon lights, color bubbles, and beautiful lamps for landscape lighting, and promote the use of LED lighting.
The city will also build a green lighting demonstration project. We will expand the trial and trial scope of new urban lighting products and new technologies, use solar energy and wind energy technologies according to local conditions, and promote new high-efficiency energy-saving light sources. We will boldly try energy-saving technologies that have passed the energy-saving evaluation of testing institutions and have obvious effects. Within the special zone and outside the SAR, new or renovated projects will be built, and one or two green lighting demonstration projects will be built, especially the projects of wind-solar hybrid power generation and LED lighting, which will become the business cards for the city to showcase energy-saving and emission reduction results.
