Guérande lights up

Share on

The town of Guérande in the French department of Loire-Atlantique has selected Bouygues Energies & Services, a Bouygues Construction subsidiary, to upgrade part of its street lighting stock and to operate the 3,000 light points in its public lighting network for a period of 15 years as part of a Public-Private Partnership. A key aspect of the PPP, due to start on 1 January 2016, is the creation and animation of a dynamic trail of light showcasing 39 important sites within the medieval town and cutting energy consumption by more than 40%, which will link in with a unique mobile app for tourists.

A dynamic, evolving and energy efficient trail of light in the medieval town

This dynamic lighting scheme will enhance 39 sites in Guérande’s medieval town and change with the seasons. At two key points in the year, Christmas and the Medieval Festival, specific lighting designs will be displayed in the heart of the historic town. The scheme will also involve schools by projecting their graphics.

In order to upgrade the lighting system in the medieval town and reduce energy consumption, Bouygues Energies & Services will also renew the 120 light fixtures by using all-LED technology and installing Citybox© units: this solution, designed and developed by Bouygues Energies & Services, makes it possible to precisely programme lighting at the light point, based on the time and day of the week, and offers access to numerous services that help enhance the tourist trail, such as PA systems.

Innovative: a mobile app for tourists that links in with the light trail

Moreover, a mobile app for smartphones and tablets will provide a geolocation facility as well as access to explanations about the various landmarks in the medieval town and to practical information about local shops.

First sites to be carried out in 2016

The 39 sites will be illuminated during the first year of the PPP. The first buildings to be showcased in 2016 will be the Notre Dame La Blanche chapel and the Porte de Saillé town gate within the town boundaries, and the sites outside the town boundaries. Fabienne Viala, Director of Bouygues Energies & Services France-West, says: “This partnership with the town of Guérande represents a benchmark for Bouygues Energies & Services as it shows our ability to offer comprehensive solutions in energy performance and city management that are ever more innovative and attractive.”
