This project will show in situ an innovative regulation system for street lighting is economically efficient and designed to reduce energy consumption of 30% of the state of the art control systems and skies light pollution of 30%.

This technology will be installed and tested at EUR residential quarter in Rome (IT). The project analyses the life cycle of the street lighting devices assessing , in an articulated urban context, the new adaptive regulation system is integrating an adaptive regulator with a series of environmental sensors. LIFE-DIADEME will analyses preliminarly socio-economic aspect and market factors of the new lighting real-time regulation system putting as objective the reduction of 10% of the maintenance costs for street lighting, of 30% the related global expenditure.

Almost part of the energy consumption in Europe depends by urban areas and produce notable emission of Greenhouse gasses (GHG). Over 90 milliion of lighting pales count more than 50% of public energy consumption and about 60% of relative costs. Street lighting play a relevant role both for the security and life quality in urban areas. Innovations in lighting like Solid State LED (SSL) promise to user an energy saving in about 50% and a notable reducing of maintenance costs. A forward integration with adaptive technologies for smart city increase sustainability in line with EU policies toward a cost-efficiency lightening and a dependent reduction of environmental impact.

  EUR quarter in Rome. Site of pilot test over ACEA SpA infrastructures.


LIFE-DIADEME project will introduce a new street lighting system aimed to energy consumption reduction by 30% in front to a 30% reduction of state of the art consumption for regulation systems. A 1’000 low cost sensor net will be installed in Rome EUR quarter, detecting noise, traffic and meteo. A additional LCA analysis will assess costs, market positioning and socio-economic impacts focusing on cost reduction for energy, maintenance, RAEE.


DIADEME is oriented to obtain by 2020:

  • Street lighting energy reduction and relative CO2 emissions of 30% in front to current pre-selected solutions;
  • Reduction of light pollution and particularly of skyglow of 30%. Road surfaces and houses reflect light, consequently a reduction of light flows directly affects on the possibility to decrease indeed light pollution;
  • A global energy saving amount of about 159 GWh per year, and a related 55’850 TEP per year of CO2 saving;
  • Maintenance cost reduction for street lighting of 10% with a 20 year based LCA analysis;
  • RAEE reduction of at least 93 tons/year and 4’180 tons/year for a EU global level adoption of the system by 2022;
  • Street lighting expenditure reduction of at least 30%
  • Transition boosting toward “green calls”.

Additional socio-economic and environmental impact are recognizable.
