Nowadays, global implementation of energy-saving and emission-reducing measures to protect the global environment and reduce the consumption of the earth's resources, and promote the development of ecological balance; people first think of energy-saving lighting and other energy-saving transformation measures in terms of energy-consuming capacity, resulting in power shortage Today, how to achieve energy saving in lighting has become a national issue. According to statistics, China's lighting electricity consumption accounts for about 12% of the country's total electricity consumption, exceeding 400 billion kWh, which is almost equivalent to the UK's national electricity consumption for one year. So we have to consider the use of large-scale electricity. Transformation and restrictions;
Strengthen urban lighting management to eliminate low-efficiency lighting products
In May of this year, the Ministry of Housing and Urban-Rural Development issued the “Regulations on Urban Lighting Management”, clearly pointing out the promotion of the use of energy-saving and environmentally-friendly lighting technologies and new products, and actively adopting efficient light sources and lighting fixtures, energy-saving ballasts and Control electrical appliances and advanced lighting control methods, encourage the installation and use of renewable energy utilization systems such as solar energy in the construction and renovation of urban lighting facilities, and propose that energy-saving renovation can be carried out by means of contract energy management. On June 17, the Ministry of Housing and Urban-Rural Development issued the “Notice on Strengthening Urban Lighting Energy Management and Strictly Controlling Landscape Lighting”, requiring strict control over the scope and scale of landscape lighting. The notice requires the elimination of incandescent lamps, high-pressure mercury lamps used in urban road lighting, and high-pressure sodium lamps, metal halide lamps and other light source products and ballast products whose energy efficiency indicators have not met the national standards. At the same time, it is emphasized again that it is necessary to actively promote contract energy management methods, and select suitable regions and road sections to conduct pilot energy management pilot projects for urban lighting energy-saving renovation projects. The release of these policies puts forward requirements for the realization of urban lighting energy conservation, and also points out the direction.
As we all know, urban lighting consumes a lot of electricity, especially in some cities, using strong searchlights, high-power floodlights, large-area neon lights in landscape lighting, and still using inefficient high-pressure mercury lamps or substandard products in road lighting. Both have caused huge waste. In addition, many large public buildings have become energy-consuming. Jiang Yi, an academician of the Chinese Academy of Engineering, used Beijing as a sample to investigate and found that the energy consumption of large public buildings is basically 10 to 15 times that of ordinary residential buildings. More than 20% of the electricity used is due to the “contribution” of lighting. Therefore, it is imperative to strengthen urban lighting management and energy-saving renovation of high-energy lighting products and systems.
Actively implement lighting energy-saving renovation
According to the instructions of the relevant documents of the Ministry of Housing and Urban-Rural Development, the curtains of lighting energy-saving renovation through contract energy management modes have been opened in many areas. Not long ago, the domestic ** large contract energy management alliance initiated by the Guangdong Green Industry Investment Fund was born. The alliance will cooperate with Guangdong Province's “Green Lighting Demonstration City” special action to carry out energy-saving renovation of semiconductor lighting in the province's public lighting system. It is expected to achieve energy saving of 60% per year, and each street lamp can reduce carbon dioxide emissions by 185 kg per year. In the next five years, most of the country will have a considerable scale of energy-saving street lamps, such as: LED street lights, low-frequency electrodeless street lights, etc. are road lighting energy-saving products.
Sichuan Province has also launched a new contract energy management policy in recent days. It has selected pilot projects in public institutions and large public buildings across the province to transform a number of electrical systems, including lighting, in a contractual energy management manner, and clarified relevant incentives. mechanism. Shanxi recently announced that it will carry out an overall transformation of the tunnels and toll stations and service areas of the 1965-kilometer expressway that have been completed and operated, using energy-saving light source technology for induction lighting. After the completion of the transformation, the power saving efficiency can reach 50%-70%, and it is estimated that at least 3500 kWh of electricity can be saved every year.
In many cities in Yunnan, Hainan, Liaoning and other provinces, the lighting energy-saving renovation with considerable scale is progressing in an orderly manner. For example, Hainan Ledong is carrying out overall energy-saving renovation of the office and county public lighting system, and promoting high-efficiency lighting products in the urban lighting fields such as offices, roads, and landscapes. It is said that the annual energy saving will exceed 880,000 after the completion of the transformation. Kilowatt hours. In these energy-saving retrofits, contract energy management is almost a commonly used model, and the bank's corporate government's approach is widely recognized. Contract energy management boosts lighting energy saving In fact, the contract energy management model has been developed in China for many years, and its advantages have been recognized in the industry. In general, urban lighting renovation is dominated by the government, and its financing problems often become the bottleneck of work promotion. The contract energy management model, with the help of the power of the bank, solves the problem of large investment in engineering, guarantees the interests of production, consumption and finance, and minimizes risks, and achieves shared results. At present, the widespread promotion of this model has also spawned many contract energy management companies, which has also greatly promoted the promotion of lighting energy-saving technologies and products.
Of course, the industry also believes that although the contract energy management model has many advantages, urban lighting, especially road lighting, is related to pedestrian safety, and lighting energy-saving renovation should be cautious. For the city management department, first of all, we should pay attention to the selection of professional energy management companies to ensure that they can provide professional services. Secondly, we should choose suitable products. For new products with unstable performance, we should use them cautiously. The way, first try to use in the secondary roads or alleys, and then gradually advance. For contract energy management companies, the specific conditions of each project are different. Therefore, the source of light, power supply, lighting quality, and lighting complexity are also different. The key is to make correct judgments and formulate efficient energy-saving. In order to achieve the best energy saving benefits and achieve energy saving in lighting.
