The Western part of the demonstration district “Ile de Nantes” is a very busy and touristic entertainment area where many urban developments are implemented in the framework of mySMARTLife. It is a vibrant place ideal for deploying and testing new solutions, in particular in the field of smart lighting.
Currently, Nantes Metropole manages around 95,000 lighting points in the city for an electricity consumption of 45 Gwh per year, an annual electric bill of around 6 Million Euros and annual maintenance and exploitation costs of around 4 Million Euros.
The opportunity of smart lighting
Smart public lighting is an opportunity to respond to changing urban challenges and stakeholders needs as well as to optimise public lighting functioning, maintenance costs and energy efficiency. Therefore, Nantes Metropole aims at designing and implementing a new public lighting concept which will increase smart lighting innovation, optimise lighting costs and reduce energy consumption.
mySMARTLife partner ENGIE designed new smart lighting solutions to respond to the citizens’ and operators’ needs and will deploy them during the first semester of 2018.
Focus on the demonstration area
The demonstration area is divided into 5 zones with specific needs:
2. The side lane of “Contre allée Mail des chantiers” is currently poorly lightened and needs to be more attractive to encourage people to use it.
3. The lighting in the street “Cité des chantiers” has to be reduced and rearranged as to guide citizens to the esplanade.
4. “Quai des Antilles” is a highly frequented zone with a need for a very efficient lighting.
5. The street “Esplanade des riveurs” has a need for switching on/off the lights according to specific events.
New efficient solutions by ENGIE
To tackle these issues, different solutions will be implemented, such as the creation of a lighting path that will be deployed by ENGIE, the French electricity company. To encourage people to use this path, new efficient LED lights will be installed with Gobo image projection in the area of “Contre Allée Mail des Chantiers”. Besides, ENGIE will install new LED lights with presence detection and dimming option in the area of “Mail des Chantiers” and “Cité des Chantiers” to encourage people to walk on the side lane of the parallel path in the evening. All light points will be controlled by a remote management system in real time. The operator will also monitor lights e. g. with an on/off switch functionality for specific events and a dimming option. Operating costs and maintenance plans will be optimised.
ENGIE will also install sensors (probably for measuring air quality and noise as well as cameras to count flows of people and traffic) to investigate interesting use cases. These sensors will communicate with the lighting network. Overall, the replacement of existing lamps by LEDs, dimming and individual lighting points remote management will enable to save 75% of energy and optimise maintenance. This new lighting system will be controlled and monitored through a flexible, open and interoperable multi-system and multi-application Content Management System (CMS). Public lighting energy data will also be integrated into the new Nantes Urban data platform.
The EU Sustainable Energy Awards are a major feature of the annual EUSEW policy conference. Twelve finalists are competing for the title of most successful project for secure, clean, and efficient energy in four categories (public sector; consumers; energy islands; and businesses). A high-level jury will decide the winner in each category. The awards ceremony is scheduled for 20 June.
Citizens are invited to vote online to pick the winner of the 2017 Citizens’ Award at http://www.eusew.eu/awards-public-vote
Gothenburg’s CELSIUS pilot project shortlisted in public sector category
The CELSIUS project (http://celsiuscity.eu/) aims to make it easier for local authorities and energy companies to develop energy-efficient district heating and cooling systems.
District heating and cooling systems are a sustainable, low-carbon way of keeping buildings comfortable and providing hot water. They provide centrally generated heat to buildings via a network of pipes.
Gothenburg is one of the project’s partner cities, along with Rotterdam, Cologne, Genoa, and London (Islington Council). The seven replication cities are Athens, Gdansk, Ghent, Gdynia, Riga, Viladecans, and Warsaw.
The project brings together 65 European cities along with other stakeholders from industry, academia, and special interest groups. Projects to test the technologies developed by CELSIUS have already cut CO2 emissions in Europe by almost €100,000 per year.
