Italian project wins EU Sustainable Energy Award for advancing the clean energy transition with its novel municipal lighting solution

LIFE-DIADEME recognised by European Commission for reducing emissions and improving pedestrian safety with innovative public lighting scheme

[Meet the other EUSEW 2021 Award winners]

Today, LIFE-DIADEME was awarded the prestigious EU Sustainable Energy Award in the Innovation category. European Commissioner for Energy, Kadri Simson, was on hand to congratulate the winners at the online awards ceremony which kicked off Day 1 of the EU Sustainable Energy Week (EUSEW). Members of a high-level jury tasked with picking this year's top clean energy projects in Europe were also in attendance. 

Commissioner Simson praised all five EUSEW Award winners commenting, "The projects and individuals that are being recognised today are not only leaders in transforming Europe’s energy landscape, they are role models. Their work is a testament to the importance of citizen engagement in making the European Green Deal a reality. We've been working hard to develop policy instruments, which guide and support action on the ground, and it is truly inspiring to see this vision at work. Together, we are bringing Europe closer to its climate goals.“ 

LIFE-DIADEME is an Italian project that offers a low-cost way to save energy in public lighting while monitoring environmental conditions. 

“We have installed almost 800 sensors on light posts in the two pilot areas in Rome, and an additional 200 in Rimini and Piacenza,” says Linda Meleo, Councillor for Infrastructure Development in Rome’s Department of Infrastructure. “It is an energy-saving technology but it also promotes pedestrian safety. Many municipalities are reluctant to implement adaptive lighting technologies for fear of lighting dimming when the conditions are unsafe, but the real-time aspect of LIFE-DIADEME overcomes this.”

Roaming the streets of Rome at night, residents can feel confident that their way will be well lit according to the outdoor conditions and without consuming too much energy. The lighting system, in parts of the city, uses close to 50% less energy than regular street lamps thanks to the LIFE-DIADEME project. 

“The primary function of the sensors is to allow flux in lighting levels across cities of any size,” explains LIFE-DIADEME Project Manager Andrea Mancinelli. “The technology is able to monitor and adapt to real-time traffic and weather conditions, while also monitoring air quality, including levels of nitrogen (NO), nitrogen dioxide (NO2), ozone (O3) and carbon monoxide (CO), all used to regulate public lighting.”

Public lighting accounts for over 50% of electricity consumption of most European municipalities, so the ability to make savings in this area is a vital step towards climate goals. With adaptive lighting, CO2 emissions savings of 55% can be measured when compared to full-light LED installations.

In the long-term, it is estimated that a medium-sized city of 100,000 inhabitants and 12,500 lighting points could save up to 6,644 tonnes of CO2 emissions over 10 years. This figure rises to 40,000 tonnes for a larger city such as Rome, with 2.9 million inhabitants and over 200,000 lighting points. In both cases, it is estimated that a return on investment can be expected in 2.5 years.

The LIFE-funded project started in 2016 in Rome, Rimini and Piacenza and is a model of smart city technology. Two key advantages of this approach to the reduction of CO2 emissions in the public sector are that it is both highly accurate and low-cost. Initiatives such as this one are bringing the EU closer to the 2030 targets

LIFE-DIADEME was one of three finalists shortlisted for the EU Sustainable Energy Awards 2021 in the Innovation category. The two other contenders in the category were RenOnBill and PERFORM

About the EUSEW Awards

Twelve outstanding individuals and projects are highlighted at the EU Sustainable Energy Week (EUSEW) 2021 for their innovation in energy efficiency and renewables. Finalists were chosen from a list of the year’s most successful projects for clean, secure and efficient energy. The awards have four categories - Engagement, Innovation, Woman in Energy and Young Energy Trailblazer – as well as the Citizen’s Award. Prizes were awarded by an expert jury (for Engagement and Innovation), and by citizens via a public vote.

EUSEW 2021

EUSEW 2021 runs from 25 to 29 October 2021, under the theme ‘Towards 2030: Reshaping the European Energy System’. Taking place ahead of the decisive COP 26, the event brings together energy policy experts, industry leaders, academia and civil society representatives to discuss how forward-looking policies for decarbonisation, energy efficiency, climate mitigation, and many others comprising the European Green Deal, can help rebuild a better and more resilient society and economy.

There is still time to attend EUSEW 2021! With more opportunities than ever to connect, engage, network and reflect on the biggest issues in clean energy in Europe and beyondMedia and participants can access the online event until 29 October.

The EU Sustainable Energy Week (EUSEW) is the biggest event dedicated to renewables and efficient energy use in Europe. The 16th edition of EUSEW will take place online on 25-29 October 2021 under the theme: ‘Towards 2030: Reshaping the European Energy System’. The Week consists of a 3-day digital policy conference, the EU Sustainable Energy Awards Ceremony, the Debate with Ambassadors, the second European Youth Energy Day, as well as 1:1 video meetings, virtual stands, and other networking activities. Participants will also have access to an extended programme and digital sustainable energy events, known as Sustainable Energy Days, which will take place all over Europe throughout the months of September and October 2021.

Launched in 2006 by the European Commission, EUSEW was organised by the Executive Agency for Small and Medium-sized Enterprises (EASME) until 31 March 2021, and as of 1 April 2021 is organised by the European Climate, Infrastructure and Environment Executive Agency (CINEA), in close cooperation with the Directorate-General for Energy.
