With the acceleration of the urban construction process, urban lighting was once considered to be a “business card†that reflects the economic development of a city, and all localities are competing to create a “no-night city†with brilliance. However, in today's vigorously advocated a low-carbon economy, urban lighting has gradually been paid attention to by others. At the two sessions that had just ended, Feng Shiliang, a member of the National Committee of the Chinese People's Political Consultative Conference, said it was amazing: the city was lightly wasteful and should stop.
CPPCC members reminded to reflect on "lighting heat"
Feng Shiliang, a member of the National Committee of the Chinese People's Political Consultative Conference, pointed out in the proposal that "the city's lighting violates the purpose of building a "saving society"", the electricity generated by a Three Gorges power station is not enough for national night lighting. Some landscape lighting lamps are expensive, ranging from a few thousand to tens of thousands of dollars. Some imported lamps even cost as much as 100,000 yuan. The annual operation and maintenance costs are simply an astronomical figure.
Feng Shiliang believes that the starting point for the lighting project should be to let the people get benefits, and to pursue prosperity but not luxury. He said that even countries with developed economies and relatively abundant energy are also very focused on energy conservation. The development of developed cities such as New York, Tokyo, and Paris is not as good as some big cities in China. So China, still in developing countries, should we reflect on the "lighting fever" that is getting worse?
China's lighting should be based on energy conservation, lighting must be based on functional needs. In Feng Shiliang's view, it is necessary to maintain the basic functions of lighting. The main street must ensure the brightness; and the decorative lighting should conform to the function of “beautyâ€, embody the cultural cultivation and cultural atmosphere, and consider the financial resources and national resources.
“Exceeding Standards†and “Not Up to Standards†for Urban Lighting
In the proposal of Commissioner Feng Shiliang, a common saying of the people was quoted: "The bustling streets are bright and crystal-clear, and the cool alleys are dark and faint." This truly reflects the current status of lighting in some cities: in the city's main roads, road lighting far exceeds the requirements of the "Urban Road Lighting Design Standards", buildings on both sides of the road also use a lot of floodlights, plus a variety of neon lights, Landscape lights, a colorful, lighting is obviously "exceeded"; and in some back streets, "there is no road, no lights, no lights" phenomenon still exists, the basic lighting is not guaranteed, the road lighting is not yet " To achieve the standard, it has caused inconvenience to the people's travel and life. This difference is even more pronounced when comparing the lighting of some central cities with remote suburbs and even rural areas.
In fact, whether it is urban road lighting or night lighting, the Ministry of Housing and Urban-Rural Development has introduced corresponding design standards and specifications, lighting evaluation indicators, lighting design, lighting energy saving, light pollution restrictions, lighting power supply and distribution and security. Etc. However, many regions have not strictly implemented this, which is the main reason for some urban landscape lighting to “exceed the standard†or “not up to standardâ€. The infrastructure construction of the city is directly related to people's quality of life. Therefore, in response to problems such as broken or missing road lighting, relevant departments need to face it seriously and improve early; for some central cities and prosperous neighborhoods, super-standard and large-scale bright Chemical engineering also requires scientific planning and strict implementation of relevant standards. This aspect is due to the waste of resources caused by excessive lighting, and does not meet the concept of energy saving and emission reduction and low carbon requirements. As Feng Shiliang said, China is still a country with tight power supply. During the peak period of electricity consumption, it has to adopt measures to limit industrial electricity consumption to ensure the daily needs of residents. Moreover, there are still many people in China who even have basic lighting needs. Unable to meet. In this case, some places are still engaged in this "virtual shelf", which is puzzling. On the other hand, some cities have spent a lot of energy to build urban lighting projects, but they have not been landscaping, but have caused pollution.
Landscape lighting requires aesthetic guidance
Landscape lighting design is a science, harmonious landscape lighting is not as bright as possible, but can highlight the city's culture and atmosphere. An experience of Professor Chen Dahua from Fudan University has been mentioned many times in the industry. He once participated in the planning and design of the Shanghai Bund night scene. In the process, the design team reduced the brightness of the lights three times to achieve the lighting effect. As a result, the Bund lighting is just right, and the environment. Very harmonious. In fact, experts in the lighting industry have reached an agreement on this issue: to avoid the disorderly development and excessive development of landscape lighting. Because over-lighting can not only add color to a city, but it will destroy the overall beauty of the urban landscape, and the serious light pollution will damage the natural environment and affect the physical health of people and other creatures. This requires the relevant government departments not to "slap their heads" in the process of building urban lighting, nor can they take it for granted that the more money they spend, the better. Urban lighting requires the involvement of professionals and requires overall planning and design.
At present, some cities have combined nightscape lighting with urban planning, and formulated urban lighting development master plans according to the characteristics of the city, so that the night lighting of the whole city is prominent and distinctive. Of course, only planning is not enough. What we need more is execution. The insiders pointed out that on the one hand, it is necessary to strengthen the management of the light environment and carry out the division of the functions of the light environment; on the other hand, it must operate strictly in accordance with the normative design standards, which is the "low-carbon" road for urban lighting.
