Chartres, a city with 40,000 inhabitants, has a rich historical and architectural heritage. It has a historical centre listed as a conservation area by French law and a cathedral which has been listed as a world heritage site since 1979.
The city’s economic development is based notably on the cosmetics sector, the city being the heart of the “Cosmetic Valley”, a competitive cluster for cosmetics boasting large groups such as MMA, Guerlain, Novo Nordisk and Lorenov.
The city’s dynamism is demonstrated by an unemployment rate 2.5% lower than the national average.
PUBLIC LIGHTING MANAGEMENT
The municipality is responsible for
- street lighting
- decorative lighting and architectural lighting
- lighting for sports facilities
- festive lighting
Lighting is maintained within the scope of an energy performance contract with global management.
Activities relating to renovation (public lighting / sports lighting / enhancement / networks), maintenance (preventative and corrective), operation and festive lighting are outsourced.
Lighting master plan
The key areas of the Chartres lighting masterplan are:
- Consistency of equipment installed (poles / luminaires / base shafts)
- Consistency of illuminance (uniformity / average illuminance / colour temperature)
- Consistency of treatment of strategic places (roundabouts / squares)
Some recently implemented lighting projects
- Treatment of globe luminaires fitted with mercury vapour lights
Two districts are involved: the Gaston Couté district and the Bel Air district.
This project consists of replacing globe luminaires fitted with mercury vapour lights with two-step LED luminaires. 42 units have been replaced in the Gaston Couté district and 32 in the Bel Air district, allowing 83% of energy to be saved for the entire project.
- Re-equipping luminaires
Change of control gear on the projector to reduce wattage (from 400W – 250W). 44 lights are concerned. The project has allowed 38% of energy to be saved.
- Treatment of Place de la poissonnerie
The project consisted of setting up LED luminaires (Stanza, Maya) as well as highlighting
maison du saumon (LED + DMX projectors)
- Highlighting the Anne Franck wall
Perspectives for the future
- Controlling consumption: continual renovation of existing material
- Incorporating new technologies relating to public lighting
- Developing towards an increasingly intelligent city (remote management of lights, presence detection, etc.)
