- In the CCIC buildings: installation of energy-saving fluorescent lighting,
- At the port: following a photometric study carried out in 2006, the following work was carried out :
- out of 135 existing concrete heaves: 8 were replaced and 66 repaired,
- the entire marina lighting setup was refitted: in addition to the new heaves and of new searchlights, lanterns were installed.
The lanterns are used according to season and location: they give off less light, and therefore consume less energy.
An invitation to tender is currently underway for:
- the replacement of the glass in 550 searchlights out of a total 750 existing symmetrical searchlights, installation of striated glass for a better distribution of luminous power.
- The installation of 13 asymmetrical searchlights, a type of equipment that offers more diffuse light, reducing wasted lighting.
Optimisation of combustion systems
- boilers: adjustment of the boiler cascade to save energy by spreading out power.
- installation of reversible air-conditioning (can switch from heat to cold air).
