Smart Building

    Two levels of sub-metering with the possibility of specific monitoring of energy consumption by item (Counts lighting, air conditioning, ECS) beyond the regulatory requirements of the energy metering

Urban environment

    The project is located in the center of Paris, in the heart of the CBD (Central Business District) in the 8th arrondissement. This location allows the building to benefit from good transportation services and easy connection with the city networks.

Reasons for participating in the competition(s)

Compte tenu des défis énergétiques à relever dans l’existant, notre opération de rénovation environnementale d’un immeuble haussmannien nous semblait être un exemple concret et reproductible des solutions qui peuvent être mise en place pour répondre à cet enjeu.

Cette opération se veut exemplaire sur les sujets environnementaux et a obtenu une triple certification environnementale :
