Zero carbon city of the future

When governments around the world are due to be oil shortage and global warming crisis, a wave of construction of "eco city" trend is on the rise. For example, Abu, a Arabia based United Nations, is about to launch an ambitious plan to build a town - MasdarInitiative (re evolution of the AbuDhabi).

The core project this plan is to be in the distance Abu Dhabi East desert area of 11 km, the development of a quanta 6.4 square kilometers of the town MasdarCity (Masdar city), the nearby Abu Dhabi International Airport New Town, is a "zero carbon" city to build target town but, Masdar will further "zero waste" and "zero vehicles (vehicles) as the main axis of development. In the city the city to sit in the southwest direction of construction, in order to obtain the best lighting and shade effect, planting a large number of planting and water facilities, and the use of wind tower facilities will cool the city in order to achieve the purpose of cooling.

The so-called "low carbon economy", refers to the least greenhouse gases in the development of the whole society, at the same time to obtain the maximum output. The future, human beings can be more use of renewable energy, to the underground storage of carbon dioxide and other ways to reduce greenhouse gas emissions, but also does not affect the citizen's social welfare and quality of life, without sacrificing the development of society and economy. Therefore, low carbon economy is considered to be following the industrial revolution, the information revolution, the fifth wave of the revolution to change the world economy, and low oil consumption will become the mainstream of future life model.

With "promote low-carbon economy", as well as attention to green consumption, green city lighting has become the focus of people hot. For the development of "low carbon economy", it is necessary to take the green route of urban lighting. To this end, the Chinese government has formulated the outline of urban green project plan for 11th Five-Year". And in 2005 as the base year, city lighting energy saving target of 5%, 5 years (2006 -2010) accumulative total 25%, according to the 11th Five-Year requirements must meet energy-saving 29 billion kwh, reduce carbon dioxide emissions 29 million tons.

In fact, Chinese city has been constantly planning and improve the city lighting system, the main line in the night: one is designed according to the function of the city, and in accordance with the city planning deployment, nightscape design characteristics and city building function mutual agreement, according to the different functional properties of streets and lots of specific the environment and the buildings, the lighting should have different atmosphere, different brightness and different style requirements; using LED light source lamp energy-saving warmer in the road, in the city public places such as parks, leisure and entertainment plaza with crown lights and small combined lamp combined cross lighting etc..

The establishment of green city lighting is not confined to the city of the new lighting system. Talking about green city lighting, we tend to think of the city is in the new lighting scheme to ensure strict control, large-scale use of green lighting, but actually neglected already exists today 718 city in 137 million 230 thousand lamp lighting, large energy consumption and they are still in Chinese city. Hidden behind a huge number of energy consumption, it brings us a formidable energy saving targets, the government needs to increase the reform of urban lighting system.

And have the same trouble in Germany has been one step ahead. In 2008 by the German Environmental Protection Agency proposed a new green lighting Contest Plan "BundeswettbewerbEnergieeffizienteStadtbELeuchtung", advocating a wide range of energy-saving lighting city in germany. The German city size of the federal states are allowed to participate, according to city lighting renovation project reasonable energy saving and environmental protection of their own, finally by the German Environmental Protection Bureau selected from all participating in the scheme of energy efficiency, the most economical and high-quality lighting technology city lighting renovation scheme and implementation of investment. After the final plan will also serve as a model by the German Environmental Protection Bureau to promote the implementation of the German city, ultimately achieve the full range of old German city lighting system gradually green update, greatly reduce the destruction of city lighting on climate and environment, the realization of "low carbon economy".

In fact to promote green lighting city competition process, the original is not Germany environmental protection bureau. As early as 2003, the global lighting industry leader PHILPS company for the global building named "City.People.Light" (city, residents, lights, referred to as CPL) international awards, aimed at using advanced and advanced LED green light of the city, and through some special visual effect and light outline the Ambilight night view of the city. So that the city more personalized, humane. At the same time to improve the safety of the residents, so that they have a sense of belonging and sense of pride in the city they live in. Just like the name "City.People.Light", the city, the residents and the lights are organically integrated, and the distance between the city and the residents is shortened by the medium of light. After 6 years of effort, as of 2008 the city has benefited from the award has been around the world, including Seoul, South Korea, Germany, Hines Begg, Austria, Vienna, Belgium and other cities.

Green and old city lighting is another problem with equal importance, city green lighting concept can not only stay in the experts and government officials advocate, some big enterprises and big city should stand out to assume social responsibility. If they can pay attention to the city of green lighting
