Not long ago, the 2010 World Cities Summit (WCS) was held in Singapore. The theme of the summit was a livable and sustainable future city, showing the solutions to the increasingly pressing urban problems of today's cities. How to improve the city's livability index and achieve sustainable urban development has also become the focus of the city planners participating in the summit. The livability index not only represents the harmony between the city and the people, but also represents the space for sustainable development between the city and the environment. In the livable city index published at the World Cities Summit, the new index is evaluated in 135 indicators in five categories. Environmental protection and sustainability, economy, domestic security and stability, quality of life and national governance capacity are both appropriate. The top five assessment categories for the city index.
To improve the environmental and sustainability index, the first thing that needs improvement is the tight energy supply and demand situation. Data shows that urban life consumes 70% of the world's energy, and 15% of it consumes road lighting. Therefore, helping city planners to reduce the energy consumption of urban road lighting, reduce environmental pollution and improve the livability of the city has become the direction for lighting enterprises to carry out technological innovation and improve lighting solutions. To this end, as a global leader in the lighting industry, Philips has proposed a green road plan to promote road lighting to save energy and reduce emissions, leading to sustainable development; safety and comfort, improve quality of life; longevity and safety, look to the future, and use this as a green The three pillars of the concept of the road. This concept, pioneered by Philips Lighting, has been fully implemented in China and has been highly recognized by municipal construction and planning companies.
At the summit, Philips also officially launched the EssentialLine series of road lighting solutions. This new LED road lighting product will provide a better choice for urban planners to upgrade their roads with high efficiency and environmental protection. It also marks that Philips Lighting has begun to introduce the livability index as a market direction in promoting the construction of green roads. The new era.
Sustainable and livable city
If the last century is regarded as an era of globalization, this century will become an era of global urban integration. The rise of Asian cities reflects a balanced state in which the global economy moves from the West to the East. In this context, small and medium-sized cities will become larger and larger, while large cities will be transformed into super-regions. Zhong Dexuan, vice chairman of the World Cities Summit Working Committee and director of the Industrial Development and Investment Promotion Association of Singapore, said. A century ago, only 10% of the world's population lived in cities. By the beginning of the 21st century, this proportion had increased to more than 50%, and by the middle of this century it would reach 75%. In Asia, a United Nations study showed that in 2008, 45% of the population in Southeast Asian countries lived in urban areas. By 2030, this ratio is expected to reach 56.5%. At present, China is carrying out the largest urbanization movement in history. In 2008, China's urbanization rate reached 45.68%, and the city reached 655. Rapid economic growth and energy consumption have brought a series of new environmental problems to urban construction planners, putting more pressure on energy and the environment. These changes will also place a heavier load on infrastructure, including outdoor lighting.
How to make the city grow and develop, not to damage the environment, reduce the consumption of energy and resources, and achieve the harmonious coexistence between the city and the environment? The programmatic document in the history of modern urban planning, the new charter of Athens, has proposed sustainable development. And quality of life as the basic goal of urban planning. This is also the core theme of Philips' City.People.Light (City. Residents. Lighting, CPL for short) concept. In the 1990s, Philips pioneered a series of research, and the idea of ​​a creative leader gathered around the world to form the entire set of CPL concepts and methodology. This is a highly integrated concept and methodology that breaks through existing knowledge and technology frameworks and looks to the future. By centralizing the views of all parties in urban development planning, it combines urban, human and lighting technologies and uses advanced lighting solutions. Make people's urban experience more abundant and convenient, and further improve the city's livability index. Since 2009, Philips has launched a series of seminars in China that focus on the CPL concept, making this concept of combining technology and human care a deep inspiration for the planning and construction of more Chinese cities.
A harmonious and harmonious city is one of the three themes of Philips CPL. Under this theme, Philips advocates that the city should be people-oriented and pursue sustainable development. While lighting meets the basic functions of people's living, work, health and safety, it is necessary to create more places where people and cities and people can communicate with each other. It also needs to bring a sense of belonging and pride to the urban residents. Buildings and roads form the surface texture of the city. With various means of transportation and access, people realize free flow in different regions and spaces. At night, the lights naturally become the baton of people and traffic, arranging the parallel between the pedestrians and the drivers.
Therefore, green roads are one of the important ways to achieve a harmonious and harmonious city. The role of green roads is reflected in the catalysis of urban life quality, which can improve the quality of road lighting, provide comfort and convenience for people's travel, and ensure the safety of driving; and use advanced technology to make road lighting system long-term and reliable, and to ensure the safety and stability of urban arteries. Operation, reducing maintenance time and costs, reducing the occupation of social resources; and improving the overall level of sustainable development and stamina reserve through excellent energy-saving performance.
The data shows that only 3% of road lighting in Europe currently uses energy-saving technologies. In China, this number may be lower. The current status quo is that most of the road lighting in China uses high-pressure sodium lamps. The high-pressure sodium lamps not only have short-lived defects and low color rendering index, but also cannot dynamically adjust the power to achieve balanced peak-to-valley energy consumption. To this end, based on the rich practical experience and research on Chinese road lighting, Philips has launched a comprehensive solution for different cities, sections and construction requirements.
Four strategies for shaping diverse urban spaces
In China, the geographical, economic, social, and cultural levels vary from city to city. There are also specific differences in road lighting requirements and implementation conditions in different areas of the same city. Specific to road conditions, for highways, trunk roads, Different road conditions such as pedestrian lanes and sidewalks, lighting should be changed in a timely manner as smooth music, and flexible matching can truly meet the lighting requirements of livable cities. The fundamental solution to the difficult problem is to require green road solution providers to have flexible and diverse product portfolios and strategies while maintaining energy efficiency.
In 2010, Philips Lighting proposed four strategies based on the balanced development of the three concept pillars to meet different road lighting needs: one, truly professional LED street lights; two, one-of-a-kind warm white light street lights; three, intelligent road lighting dimming system Fourth, energy-saving high-efficiency high-pressure sodium lamp. The construction departments of different cities can be combined according to their specific needs.
The LED street lamp, which has been widely concerned by the industry, has many advantages such as high color rendering index, uniform illumination, high luminous efficiency, long life and intelligent dimming. It can save up to 45%, and the light output efficiency can be doubled every two years. These two values ​​are still rising. In the case of ClearLine, it not only has a life span of 50,000 hours, but also greatly reduces maintenance costs. With Step Dim, the Philips road dimming system, it can save an additional 50% energy consumption during non-traffic peak traffic hours; and forward-looking models The group design makes it easy to upgrade, reduce maintenance costs, avoid waste of energy resources, and benefit municipalities and taxpayers. From Zhengzhou Back Street Alley Reconstruction Project to Wanbao Street, Longquan Street and Baoling Street in the Industrial Zone of Dalian Economic and Technological Development Zone, to Kunshan Enterprise Science and Technology Park Road, Beijing Second Intermediate People's Court South Road, Mianyang Cotton The North Road of Mt. and the main roads of Mianyang to Beichuan, Philips ClearLine has become a high-quality model for the construction of green roads in China's cities, enabling people to enjoy the nightly excitement of the city more safely and comfortably. A friendly relationship between the city and the environment.
The warm white light road lighting system is another important green power in the four roads of Philips road lighting, and the Philips LED road lighting system constitutes a golden combination of new efficient road lighting systems. It is characterized by a color close to the sun, significantly improving visibility, making it easier to distinguish the details of the road and the surrounding environment, and raising the safety and comfort of road lighting to new heights, while achieving comprehensive energy savings of up to 44%. And won the industry's prestigious British lighting design best light source and electrical awards, known as the road lighting replacement model. At present, green dressing has been realized for Shanghai Luxi North Road, Jiading New City Road, Chongqing Zhongshan 4th Road, Guanyin Bridge Tunnel, and Hengyang Hengzhou Avenue.
In addition to the four strategies, Philips' cooperation with street lighting management departments across the country also includes software services to improve the level of energy-efficient lighting applications around the country. Not long ago, Philips and the Chongqing Street Light Bureau set up the first green road lighting training base to provide more training for green roads to more grassroots units.
The development of green roads, in addition to the promotion of software and hardware levels, also needs institutional support. In May 2009, Philips said that it provided financial support to users who were willing to make green renovations and lacked initial funding, which opened up new ideas for the development of green lighting in the industry. Now, Philips intends to introduce a contract energy management model in the green road sector to increase customer enthusiasm, recover investment and profit from the benefits of energy-saving transformation.
Livable and sustainable development have become the key words for the city to portray the future development. With its advantages in energy conservation and building a more harmonious city, environment and residents, Philips Green Road will become the unanimous choice of tomorrow's cities and a model for a sustainable Chinese-style livable city. Advanced and innovative technologies are the means to achieve this. Efficient green road lighting solutions, represented by Philips LED street lights and warm white light road lighting systems, will help urban planners build safe, comfortable, stable, prosperous and sustainable modern cities. Create a beautiful green future for the city
