Shenzhen city lighting legislation hearing opinions were adopted
It is reported that the Shenzhen Municipal Government Legal Office issued the "Shenzhen City Lighting Management Measures (Draft for Comment)" (hereinafter referred to as "Measures") legislative hearing report, and some of the hearing opinions were adopted.
In order to strengthen urban lighting management, improve urban lighting environment, and promote energy conservation, the Municipal Urban Management Bureau drafted the “Shenzhen Special Economic Zone Urban Lighting Management Measures (Draft for Review)†to be submitted to the Municipal Legal System Office for review. The Municipal Legislative Affairs Office has solicited the opinions of all relevant government functional departments, district governments (including the new district management committee), relevant industry associations and enterprises, and publicly solicited opinions on the government website; organized relevant departments and districts to participate.

According to reports, does the network hearing mainly focus on the scope of landscape lighting? How to scientifically and rationally define the scope? Should landscape lighting facilities be “designed, constructed, and delivered at the same time†with the main project (three simultaneous)? How to implement the three simultaneous requirements? How is road lighting energy-saving and environmentally friendly? And other issues are going on.
The reporter learned that most of the hearing statements stated that the scope of landscape lighting needs to be limited and reflect local characteristics. In view of the fact that the city has promulgated and implemented the “Shenzhen Urban Lighting Special Plan†(hereinafter referred to as the “Special Planâ€), it is recommended that the scope of landscape lighting be set according to the special plan. The hearing statement person recognizes the requirements of the “three simultaneous†landscape lighting facilities and the main project, and believes that this regulation can avoid repeated construction and construction and waste resources. As for how to implement the three simultaneous requirements, the hearing statement holders believe that planning, construction, and urban management departments need to cooperate with each other.
At the same time, the hearing statement holder believes that road lighting should be energy-saving and environmentally friendly, and it is recommended to promote the use of LED energy-saving lamps or remotely control IoT street lamps or xenon lamps to replace traditional high-pressure sodium lamps. There are also hearing statements that suggest the use of the EMC contract energy management model, which not only reduces the burden on the government, but also achieves the goal of energy conservation and emission reduction. There are also some hearing statements suggesting that the competent authorities should reasonably control the opening and closing time of street lamps to ensure that citizens can travel safely and also avoid light pollution.
In response to the above opinions, the “Measures†intend to clarify the key areas such as important landmarks and nodes of cities, major landscape corridors, and important traffic portals. Landscape lighting facilities should be set up in accordance with the requirements of the “Special Planâ€; it is proposed to implement three simultaneous construction projects. The land transfer contract shall specify the planning requirements for the landscape lighting facilities. The construction unit shall send the design plan of the landscape lighting facility to the competent department for technical advice, as the receiving requirement for the planning of the land project to issue the construction project planning permit, and specify the relevant contents in the permit; the competent department shall be required to establish the intelligent lighting of the city. The control system realizes the scientific switch light and brightness control of urban lighting facilities, and promotes the use of energy-saving and environmentally-friendly lighting new technologies, new products and new equipment, strengthens energy-saving publicity and organizes energy-saving training, etc., to achieve green lighting and intelligent lighting.
In the next step, the Municipal Legislative Affairs Office will continue to revise and improve the Measures and submit them to the municipal government for deliberation as soon as possible.
