With five buildings spanning an area of 38,400 m², the Cité Marianne in Lille is one of the largest civic property projects in France in recent years. The administration complex serves as a workplace for around 20 state departments and over 2000 civil servants. With its architectural concept, which is strongly focused on bioclimatic criteria, and its technical equipment, the Cité Marianne is also the largest passive service complex in northern Europe – with photovoltaic systems covering an area of 2700 m², complete utilisation of rainwater and high biodiversity with 216 new trees, green terraces and hanging gardens.
In addition, an important contribution is made in all five buildings by energy-efficient and convenient lighting control from ESYLUX. APC presence detectors with integrated DALI-2 control unit combined with BMS presence detectors as input devices increase the flexibility in reversible offices, for example. When modular partition walls are opened and closed, the presence detectors automatically activate a different group scenario, whereby parameters and functions are easily adapted to the change in the room's use.
