Operated offices: free yourself from the day-to-day management of your office building

The Marquise de Pompadour did not always live at the Château de Versailles with Louis XV. Before that, at the very beginning of her marriage to Le Normant d'Etioles, she occupied the private mansion on rue Saint-Fiacre in Paris. Now an office building, Saint-Fiacre is undergoing a renaissance, orchestrated with care to minimise the carbon impact of the works. Matthieu Péchard, our technical manager for the office division, explains.

​​Classé ​au ​patrimoine​ historique de la Ville de Paris, l’ensemble immobilier Saint-Fiacre a vécu plusieurs réhabilitations. Ainsi, au début des années 2000, son sous-sol a été aménagé en parking. Une aubaine, à l’heure où le stationnement dans la capitale constitue une vraie gageure ! "Lorsque le dernier locataire a émis le souhait de quitter l’immeuble, la question d’une restructuration complète s’est posée, indique Matthieu Péchard, car le confort n’était pas optimal pour les occupants. Pourtant, pas question de toucher à la structure – le toit, l’enveloppe, les façades ou les menuiseries -, protégée au titre des Monuments historiques."

2 years to go green and 34 tonnes reused

However, the entire interior layout has been redesigned. Gecina wanted to make the works an exemplary site in terms of the circular economy. We put out a call for tenders for the services of a specialist environmental consultant,’ recalls Matthieu Péchard. The Bouygues group's ELAN company was chosen, and it joined forces with Tricycle to strip out the interior of the building, in other words to ‘clean out’ it. Carried out by workers on integration schemes, as required by the call for tenders, this clean-up encouraged the reuse and recycling of materials and equipment. For example, we donated the kitchen to Le Paysan Urbain, an association, and offered the light fittings to La Grande Coco, a third-party architects‘ centre,’ he continues. And anything that couldn't be reused was deposited on the Baticycle digital platform, developed by Tricycle.’

The project was also supported by Proclus, a company that reused and reconditioned technical components such as electrical panels and air conditioning units. Proclus reconditioned them, giving them a second life. In total, more than 34 tonnes of equipment were reused on this exemplary site.
