Innovative Solutions for Public Lighting in Smart Cities

The innovative solution proposed by the DIADEME project, co-financed by the EU LIFE Programme, can be introduced as a new smart system dedicated to street lighting in urban environments for real time adaptive regulation of light flow, based on the surrounding brightness, traffic flows and weather conditions (Distributed Adaptive Installation DAI). A system providing, at the same time, a correct lighting level in terms of safety, as prescribed by UNI 11248, but also economically efficient and with a significant reduction of energy consumption.

1,000 DIADEME Devices have been installed in Rome City Capital, Piacenza and Rimini: 900 DIADEME standard (providing adaptive lighting and noise level), 50 DIADEME Air Quality Sensors (pollutants level), 35 Diademe LTM (traffic flows monitoring and lighting level control) and 47 informative Notice Boards in each street involved in 4 Test Sites.

In Rome, the data provided will be integrated into the City Data Platform and the data analysis will allow the set up of a Smart Citizen Wallet with the aim to promote virtuous behaviours and better public services.

The results of the project highlighted attractive performances in Rome, Piacenza and Rimini, demonstrating a reduction of energy consumption and GHG Emissions much greater than expected, compared with the pre-programmed systems (-40 %), today state-of-the-art Urban Public Lighting and with full light not-regulated systems (-57 %).

The Life Cycle Assessment moreover demonstrated the relevant impacts of the installed system on the reduction of energy, maintenance and electronic waste costs. Assuming the case of a medium-sized EU City of 100.000 inhabitants with 12.500 lighting points, the installation of 3.750 DIADEME Devices would cost approximately €270,000. In 10 years, we would have savings for €2.9 M. (vs. full light) or €1.7 M. (vs. pre-regulated) with CO2 emissions avoided of 6.700 tCO2e to 3.700 tCO2e. Return on Investment can be calculated in not more than 1,5 - 2 years.
