Hôtel de la Marine in Paris.

In 2015, the Ministry of the Navy left the Hôtel de la Marine in Paris to join the new site of the Ministry of Defense south of Paris. The monument was then entrusted to the Center of National Monuments. The objective was to restore the building and allow visitors to relive the time of the Crown Furniture during its construction in the 18th century. The mission assigned to us through the company EPLS involved implementing a system for controlling various types of DALI luminaires (LED strips, wall lights, spotlights, chandeliers, etc.).

The Solution.

After the creation of a prototype that was approved by the project management, including the Center of National Monuments, we were entrusted with the deployment of the LOYTEC solution for the control of all luminaires. The building is divided into levels (ground floor to 4th floor), and each floor is further divided into several zones, with respective luminaires managed by LOYTEC’s L-DALI controllers. Each open space is treated as a separate office. Each office is automatically controlled as follows:

A lighting regulation function (called CLC by LOYTEC) controls the light intensity (no color temperature management) based on the brightness indicated by the master multisensor and the occupancy state provided by the zone’s multisensors. The zone is considered unoccupied after a 15-minute “non-detection” delay. A default target of 350 lux is set for each zone. Nevertheless, the user has the option to adjust the light intensity using an infrared remote control called L-RC1 by LOYTEC.

The offices and prestigious areas are controlled in the same way. However, installation precautions were taken differently to comply with architectural constraints. The installation, granularity of multisensors, and luminaires were defined by the electrician responsible for the electrical lot.


Thanks to LOYTEC technology, the lighting is completely autonomous, and operating based on occupancy detection and manual control. This autonomy enables substantial cost savings in the context of operating expenses management.


Despite not being connected to the Building Management System (GTB), the system is interoperable and allows for easy communication with any supervision system using BACnet IP. The solution from LOYTEC allowed the customer to maximize energy efficinecy and reduce overall costs for the lighting control system.
