Today, cities consume over 70% of the world’s energy supply. And lighting accounts for 19% of the world’s electricity consumption, with some 60% of this used by commercial and public buildings in cities, and around 15% by street lighting.
Significant savings are possible – on average 40% – simply by switching to energy-efficient lighting technologies such as LED. At a global level the potential savings amount to €128 billion in reduced electricity cost and 670 million tonnes of CO2, or the equivalent of 642 power plants.
Philips is working with a range of partners from both the public and private sector on integrated lighting solutions to help build intelligently connected cities.
Livable cities require lighting systems that can adjust to the ebb and flow of traffic and urban activity. The CityTouch management system that has been developed enables dynamic and flexible control of lighting city-wide. Combined with LED-based fixtures, it can save up to 70% on energy and maintenance costs compared to conventional lighting.
A pioneering project is being implemented by the city of Buenos Aires that is renewing its street lighting system with LED technology. The majority of the 125,000 existing street lights are being replaced with new LED luminaires over 3-years enabling energy savings estimated at more than 50% for the city, a significant reduction in CO2 emissions every year. The lifetime of the LED technology is five times longer than conventional lighting.
