Owned by Foncière des Régions since 2001, the pre-existing building, located in Levallois Perret, has been occupied by Orange since its construction in the 1970s. The release of the telephone operator in 2014 was partial, Orange retaining its Equipment in the basement of the building. The small residential building on the street and the main office building, set back from the rue Anatole France, were razed to the site of the construction of a new building, seven floors, called Thaïs. This one meets the best international standards: NF Tertiary Buildings Approach HQE level Excellent and BREEAM Very Good level.

In order to reduce its carbon footprint, Foncière des Régions has been conducting LCAs on development or renovation projects since 2010. As for the Thaïs building, it wished to obtain the BBCA label. Without resorting to wood construction, the virtuous solutions it has implemented have enabled it to achieve this objective. It was awarded this label on 4 April 2017 in the Offices category awarded by the Association for the Development of Low Carbon Building (BBCA).

The building has been designed for openness and lightness, thanks to a sleek and elegant façade, combining glass, aluminum and stainless steel. On 5600 m², the choice of materials, the treatment of the spaces and the comfort of the occupant contributes to the attainment of a high level of well-being. Thaïs has large office desks that offer maximum flexibility. The new architecture reappropriates the writing of the previous book and transforms it to offer a large place to biodiversity and spaces of conviviality. The 1200m² of gardens and vegetated terraces are part of a global approach to fauna and flora, led by an ecologist. This strong footprint in the heart of town is a major point of this operation.

Architect (DGM Architects), AMO (Citae), general contractor (Petit), thermal engineering office (BETEC), ecologist (UrbanEco) and landscape architect (Terabilis) , MOEX (SCO) have mobilized to achieve the optimum environmental quality of the Thai building.

Indoor Air quality

    An indoor air quality plan has been developed. All interior linings are class A +. The ventilation rate goes beyond the statutory flow (30 m3.h.occupant) with a restart before occupation programmed by GTB. The networks were clogged systematically during the works in order to maintain the cleanest networks possible before commissioning. The waterproofing of the networks is class B, measured at the end of the work. The certified seal of the CTA is class L1.

    The double constraint [structural on the one hand with the conservation of the infrastructure and contextual on the other hand, as road classified side facade street] imposed the realization of a building in light structure and a very neat treatment. This made it possible to achieve the basic level of certification NF BATIMENT TERTIAIRES HQE DEMARCHE, with however the respect of the level Performant on all criteria outside the acoustics of facades. The interior acoustics were therefore very high.
