LACROIX City and Villefranche-sur-Saône Get ready for tomorrow's lighting challenge
03 January 2020
LACROIX City
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
Optimise maintenance 
• By reducing the technicians’ night shifts in order to ensure their availability.
• By monitoring the correct operation of the installed fleet.
• By receiving alerts about malfunctioning installations.
Measure and analyse performances 
• To rank future investments by identifying installations that require an urgent refurbishment.
• To demonstrate the savings made in energy and operation costs following a retrofit.
Test future-proof solutions 
• 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.
