Energy-intensive building

Doge is a new office building developed by Nacarat and built by Rabot Dutilleul Construction at EuraTechnologies, an eco-district of Lille dedicated to start-ups. The building features a unique brick facade designed by architect firm Tarabusi. The program provides its users with eco-designed, modern, integrated, open and particularly environmentally efficient offices. The Doge is indeed the first program in the Hauts-de-France region to be Breeam certified "Very Good".

Sustainable development approach of the project owner

Participating in shaping an intense city that is both environmentally friendly and environmentally friendly is an exciting challenge. Alongside elected representatives, communities and with our partners, we (Nacarat) try to provide answers to societal and ecological issues of the city. While assuming our position as an economic player, we are committed to producing buildings that improve the environment in which they fit: creating economic value (corollary of employment and other social values) and restoration the ecological value of the territories. Evaluated on the basis of the ISO 26000 standard, Nacarat's commitment to sustainable development is based on the ASAP * eco-design tool, developed by the company on the basis of international work on the sustainable city ( LEED, BREEAM, HQE, Living Building Challenge, Positive Economy). To progress and be successful in this area, Nacarat partners with experts specialized in areas such as biodiversity, energy efficiency, renewable energies, pedagogy ... These initiatives develop as many concrete solutions, on 15 specific themes, in particular, to promote urban mixes, create links and add a dose of enthusiasm to the concept of living together. * As sustainable as possible / as sustainable as possible

Architectural description

Inaugurated in June 2017, the "Doge", a tertiary operation of 5 100 m2, is part of the ZAC des Rives de la Haute-Deûle. The development of this sector of the Lille metropolitan area is based on the former spinning mill Le Blan and Lafont, flagship of textiles in the early twentieth century, which closed its doors in 1989, leaving 2,500 people unemployed. Remarkable "château de l'industrie", the factory rehabilitated by Vincent Brossy now hosts a business incubator in the technology and communication sector. The brick ship trades warp and weft fabrics for fibers and nodes of computer networks, within a neighborhood whose name, Euratechnology, affirms the persistence in the mutation of economic activities.

The offices of the "Doge" accompany the growth of this business park. The specifications established during the competition organized by the developer at the request of the developer prescribed the use of terracotta to meet the local context. A constraint that the architect Paolo Tarabusi has interpreted in an original way. Rather than a brick apparatus, Tarabusi chose to use in front a product usually used for the realization of jamb in the individual habitat. Raw and uncoated, this element from the Terreal catalog gives its identity to the project. The approach is not unlike that of another architect, such as Tarabusi, a Genoese living in France, Renzo Piano, who turned clay shingles to pose on the front of a set of housing built rue de Meaux, and then declined the process in several projects.

The application of the catalog product to the tertiary sector required only a minimal adaptation, compatible with a tight construction budget. The jambs are made in pairs, and come out as twinned extrusion lines. The two pieces arranged in a mirror are separated by the breakage of a hollow line. It is precisely this pathway introducing a deliberate fragility that has been removed from the production line. Becoming a monolith of terracotta, the piece has a cavity that has been filled with cement reinforced with two strands. The brackets of the concrete elements were sealed in this concrete. Placed along a gap both full and empty, the terracotta mullion is the only vertical part of the facade. It is cut horizontally by a prefabricated white cement strip that marks each floor height, a mineral evocation of the light stones inserted into the brickwork of the facades of the region. A ceramic piece also available in the Terreal catalog has made the corner fittings, adapting to situations where the facades do not follow a perpendicular geometry.

1500 pieces were laid on the entire building using dry assembly methods. A rationalist at heart, Paolo Tarabusi wanted to reveal to the aware eye the non-wearing nature of the façades, by creating a hollow between the terracotta and the concrete. The wood joineries have been set back, and their vertical uprights are concealed by the facade elements. Vibrating vertical lines of "combing" intended to hang the coating on the jambs, the Doge can appear closed in its radicality. An impression of fortresses that dissipates once inside, largely open to the neighborhood.
