Sequana—also known as the Mozart Building for a long time—and its two accompanying buildings were built on the site of the former EDF building. In September 2007 the project was sold to investor Les Docks Lyonnais. Opened three years later, the Sequana building is now the workplace of 2,400 Bouygues Telecom employees.
Designed by Bernardo Fort-Brescia of international architectural firm Arquitectonica, the Sequana tower is the result of work on curves and light. It is easily recognised from a distance by its elliptical silhouette. The same elegance is found in the interior decoration, as a result of the involvement of another renowned architect, Jean-Michel Wilmotte. The highlight of this building is the external lighting of the façade: the work of AIK-Yann Kersalé, it is unique in Paris.
Sequana is an outstanding example of energy efficiency. It was one of the very first high-rise buildings to be certified against the NF Bâtiments Tertiaires HQE® standard; it in fact largely exceeds the requirements. It makes an energy saving of more than 40% compared to traditional buildings compliant with the 2005 thermal design code (RT 2005).
Its energy and environmental performance led to Bouygues Immobilier winning the 2007 ‘Eco Building’ prize in the ‘Very Tall Building’ category.
- Renewable energies and energy efficiency:
- 1,000 m2 of roof, with 450 m2 of photovoltaic panels
- The north and south walls are double-skin façades to optimise energy exchange between the inside and the outside.
- Priority to day-lighting:
- Optimum orientation of the building to promote uniform natural light levels for all occupants.
- Automatic variation of light levels on landscaped office floors in accordance with ambient light levels and presence of personnel.
- Regulation of heating, air conditioning, and ventilation:
- Ice produced at night to optimise power consumption of the air-conditioning system.
- Air conditioning controlled by a Building Management System (BMS).
- Automatic adjustment of ventilation levels in meeting rooms, depending on number of occupants.
The Sequana building was designed to promote contact and interchange by occupants. It is therefore equipped with:
- a 350-seat auditorium,
- a sports room,
- 2 staff restaurants and a cafeteria,
- a medical and social centre,
- a special area dedicated to amenities such as a hairdresser’s, a cash point, a dry cleaner’s, etc.
