Reflections: Problems of Urban Lighting in the Past

Release time:2019-05-10

China's urban landscape lighting is not purely to beautify the city, but also undertakes a lot of other functions. But so far, the development of urban landscape lighting has been out of control. Cities build landscape lighting in various regions without restriction, and many problems have arisen, including later maintenance, environmental pollution, energy consumption and other issues. When we communicated with the relevant leaders of the Ministry of Housing and Construction in the past few days, we also pointedly put forward several problems and countermeasures.

The first is light pollution - too bright, too bright, too dynamic. We want to control it from the point of view of design master plan. Before designing urban landscape lighting, every city should formulate a general plan which has been proved and evaluated by many parties, and then implement it strictly according to the general plan. I think that in this way, the problems of urban landscape lighting in the future will be reduced a lot.

The second is the issue of funds. At present, some projects in our country will involve the construction of debt, and some corresponding measures taken by the government to develop the economy, such as PPP model, or try to repay the money after the construction. We also pointed out with the Ministry of Housing and Construction that this situation should not be one-size-fits-all. After all, China is so big that some areas with abundant tourism resources are backward and poor. In order to seek change, we need to stimulate the tourism economy at night through the input of lights. At this time, the government needs to invest funds, but in the early stage, we should do a good economic evaluation, not blindly invest.

The third is the volume of buildings, such as lighting shows and media buildings. We believe that we should control the volume of the area and its impact on the surrounding environment. For example, the media facade can not be built in residential areas, because the residential buildings and buildings are relatively close, if the installation of media facade, it is easy to affect the normal life of the residents of the opposite building. Then is the city's functional areas, if some functional areas are not suitable for media building should not be done.

There is also the problem of following the trend. Media architecture began to appear in 2013 and 2014, to G20 to Xiamen, Qingdao and now to Shenzhen. Maybe these design methods will be fresh at the first time, but when several cities are doing the same in succession, the problem of one side of a thousand cities will come. For example, on both sides of a river, our basic design method is to install media buildings along both sides of a river, but in doing so, we ignore the characteristics of each city and can not tell which city it is standing on the river. As a matter of fact, Jianghe and architecture have their own characteristics. Lighting design should be combined with these spatial characteristics and historical culture, rather than using simple media architectural design methods.

The last question concerns the government's attention. At present, the government will conduct a comprehensive review or review of some existing projects. We also propose that the industry should check itself and rectify itself. Urban landscape lighting has risen to the height of relevant management functions. In the past, our lighting landscape lighting was only concerned at the level of Management Committee in some cities, but now it has risen to the level of attention of ministries or the State Council.

To some extent, our urban landscape lighting has become an important means to stimulate domestic demand. Personally, I think this is a good thing, but whether it can develop sustainably and healthily in the future needs to be jointly discussed with relevant management departments, design departments and industry experts, and strictly controlled from the planning, design and construction process.
