Energy-intensive building

Haussmann type building for office use, located at 10/12 rue d'Anjou in the 8th arrondissement of Paris.

The construction of the building dates from the years 1880-1890. The current building is consiste of 6 storeys and 4 underground levels levels. In superstructure, the building develops 4 wings around a private central courtyard.

The works involves the renovation of office space, excluding fittings and furniture, and including the change of floor coverings and interior walls, suspended ceilings and the complete overhaul of technical equipment (heating, air conditioning, electricity ...).

Sustainable development approach of the project owner

The contractor wished to have this operation following an Environmental Quality approach. He decided to launch the project in a HQE certification approach for Tertiary Building Renovation in its version of 25 January 2013.

Architectural description

The construction involved the renovation of office spaces, without interior arrnagements and furniture, and including the change of floorings and interior walls, suspended ceilings and the complete overhaul of technical equipment (heating, air conditioning, electricity ...).

Building users opinion

To meet the goals of the environmental certification of the building and to follow the satisfaction of the inoccupants after they moved in, a commissioning mission will be undertaken.

Systems

Heating system :

Urban network
Fan coil

Hot water system :

Individual electric boiler

Cooling system :

Urban network
Fan coil

Ventilation system :

Double flow heat exchanger

Renewable systems :

No renewable energy systems

Contractors wished to connect to the urban networks (heating and cooling)

Smart Building

BMS :

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

Biodiversity approach

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 :

- HQE -Niveau EXCELLENT
- BREEAM -Niveau VERY GOOD
- LEED -Niveau SILVER
