Energy-intensive building

GECINA presents 55 Amsterdam located in the 8th arrondissement. This beautiful building offers ample living and service areas for up to 850 employees. 12 350 m² of new Parisian workspace that Naud and Poux Architectes have reinvented to work better combining historical and contemporary dimensions, architectural and environmental innovations. The access facilities of an address near a major Parisian hub of Saint-Lazare. The building benefits from the highest environmental standards with the Well, Effinergie, BBC Rénovation labeling as well as the BREEAM Outstanding, Leed Platinum and HQE Renovation certification.

The restructuring of the 55 illustrates the quest for excellence and innovation developed by Gecina.

Architectural description

As an existing building, the architectural concept has endeavored to conserve as much as possible all the elements that can be reused and reused to maintain a virtuous carbon footprint. In this continuity of idea, the project is conceived with a real adaptability on the medium and long term with much flexibility in its daily use but also a great resilience on the challenges to come.

The intervention focused on the use value of construction dedicated to an office assignment. Thus, the facades have been preserved largely in their structure and in the dimensioning of the wide open bays; The façades have been endowed with innovative elements such as a white external exterior cladding (external thermal insulation), pivoting frames on a vertical axis for reinforced domestic use, terraces cleared of any technical equipment allowing a real use, ... The light / day coefficient has been considerably increased in the low levels thanks to the brightness of the new white material, the working areas have been positioned only in direct lighting, allowing at the same time to offer horizontal and vertical Natural light. The large staircase shares with the 3 lifts an open common landing, naturally lighted which offers so many places of conviviality. The level on the first basement is also naturally illuminated either by glass floors for meeting rooms and restaurants, or by openings on the street side, or by the creation of a garden for the conference room .

The project gives pride of place to the contribution of natural light in the project which constitutes in all points of view to inscribe the project in a true environmental approach of common sense.
