LACROIX and Villefranche-sur-Saône prepare the lights of tomorrow

  • Smart Lighting

Villefranche-sur-Saône, located in France (69), has a fleet of approximately 4,400 light points and 136 cabinets, which are generally in good operating condition.

The development priorities for Villefranche-sur-Saône

  • Secure the intervention of technicians in the field.
  • Control operation and maintenance expenses to fund future investments.
  • Identify potential savings opportunities (operation, energy, maintenance).
  • Enhance the attractiveness of the city center.

In order to define its needs and to develop its future lighting management plan, Villefranche-sur-Saône has launched its first testing phase on two pilot sites.

The town has targeted:

  • A cabinet management solution only.
  • A cabinet management solution up to the light points.
  • A detection solution.

Various test objectives

• For the control and management of the cabinet and/or light points.

• To adapt to the future developments of the lighting fleet..

Villefranche-sur-Saône in numbers:

  • 136 cabinets
  • 4400 light points
  • 82,5 km of lit roads
  • 37000 inhabitants
  • 75% of the fleet is in good condition
  • 10% of the fleet has LED bulbs

The fleet has been gradually updated, and today 10% of light points have LED bulbs installed. Cutting the electrical power and turning to more effective lighting fixtures, have enabled the town to reduce its energy consumption by 8% over a period of six years.

Tegis®, proven savings

The installation of Tegis lighting cabinets before an update allows us to easily measure and demonstrate the energy savings that are obtained after improvement works. At a later stage, we will use Tegis to monitor the performances in terms of the operation and consumption of the improved installation.

Convincing results

  • Improvement of the operating conditions by analysing prior events.
  • Maintenance savings thanks to remote modifications to the lighting and shutdown schedules of cabinets.
  • Monitoring of the fleet’s energy performances, which enables the identification of installations that need to be urgently updated and to quantify economic gains.
  • Confirmation of the need for scalable solutions, to adapt the deployment of smart management to the current rate of investments.
