July 25, 2017: A new report by Philips Lighting and the World Council on City Data (WCCD) discloses how cities worldwide can reduce energy consumption and carbon emissions substantially by using smart LED street lighting systems.
Philips Lighting has underlined the need for high-calibre data to understand the value of LED lighting systems. The company has, therefore, partnered with WCCD to address this need in cities around the world.
The report presents the experience of the two WCCD Foundation Cities–Los Angeles and Buenos Aires–that have implemented major programs to change street lighting to high-efficiency LEDs as well as adopting the CityTouch smart system to manage their lighting networks. These types of solutions have immediate positive impacts that combine significant energy cost savings, reduced carbon emissions, improved system reliability, and reduced maintenance workload.
According to the new report, ‘The Citywide Benefits of Smart & Connected Public Lighting’, Los Angeles has achieved energy savings of 63% in 2016 by installing smart LED lighting systems. The city could save US$ 9 million and also reduced annual greenhouse gas emissions associated with public lighting by 47,000 metric ton.
Similarly, by adopting smart LED street lighting systems, cities worldwide can also reduce their annual emissions and cut down on electricity expenditure.
According to the report, there are about 300 million streetlights across the world, and only about 10% are high-efficiency LEDs, and just 2% are connected. Combining high-efficiency lighting with connected system management can deliver energy savings of up to 80%.
Improved lighting can also generate a wider set of benefits at the city level, such as reduced crime rates, improved citizen perceptions of safety, improved traffic safety for all road users, and significant contributions to city attractiveness and economic vitality. Los Angeles witnessed a 10.5% drop in crime rates for offences such as vehicle theft, burglary and vandalism in the first two years of its LED conversion program.
Quantifying many of these significant positive impacts from improved lighting at the city level is possible through WCCD ISO 37120 data. ISO 37120 defines a comprehensive set of 100 standardized indicators that enables any city, of any size, to assess their performance and measure progress over time and also draw comparative lessons from other cities.
