MARCO POLO

Implementation of iconic BOUYGUES BATIMENT GRAND OUEST (ex Quille Construction).

The building has undergone an energetic and environmental renovation in 2012 and 2013. He is now certified HQE RENOVATION and BBC RENOVATION.

The conventional energy consumption was reduced by 40%. The overall energy bill was reduced by more than € 25,000 / year.

Historically, the building was developed by CIRMAD PROSPECTIVES and built between 2001 and 2003, according to HQE standards.

Building delivered in 2003, very functional, including modular spaces:

7220m² of offices (some spaces that can be transformed into shops)
450m² of technical rooms
An inter-company restaurant
A gym space, equipped with toilets, showers, infirmary
440 underground parking spaces
Each floor has two toilet blocks, two tea rooms and several meeting rooms.
The top floor offers a "Club" and VIP space.
The central patio is vegetated.

Sustainable development approach of the project owner

Project certified HQE Renovation by Certivéa. The particular strengths of Environmental Quality are:
Adaptability of the building (offices / shops / Restaurant / sport and high divisibility of the building)
Improvement of biodiversity and of the initial sealing rate
user comfort (olfactory, thermal, visual)
Energy efficiency, energy management
Space management, integration of the site
Bouygues Bâtiment Grand Ouest has worked with the engineering office HQE «ELAN» to define an environmental profile adapted to the owner’s commitment and to the context of the operation.

Architectural description

The building is used as offices, is composed of 5 stories and 2 basement levels with a total area of 7906 m² useful, including 7393 m² of offices and 513 m² of technical rooms and sports hall on the ground floor. It also has 440 parking spaces in the basement. Floors, covering an area of about 1500 m², are bright and very functional and allow a very good horizontal divisibility. These floors have a high ceiling of 2.60 m and are laid out around a monumental hall on 3 floors and a vegetated patio. With a depth of 14 meters, they can both operate as open-space partitioned into individual offices. They are served by 2 lifts. The building has a polished concrete facade and a zinc roof. The building also has a Restaurant Inter Company located on the ground floor.

Smart Building

BMS :

Implementation of the Counting Plan : Exhaustive (heating, water, electricity, air conditioning, lighting, sockets), counting by area and information stored locally (more than 65 counters).

Smartgrid :

A supervision for monitoring energy consumption and developement of awareness among building occupants.

Users’ opinion on the Smart Building functions : Special attention was paid to the building management system which covers the comfort parameters of heating/air conditioning and of lighting. For lighting, a 1st and 2nd day regulation has been set up (regulation according to the natural light). The user is left free to relight if necessary. In the evening, after the departure of the last collaborator, building switches to «vacancy» mode, which is the complete extinction of lights. This mode is set up for the lowest energy consumption possible without compromising the rebooting the next day. Combining the real needs of the building and automatisation of key systems, Building Management System allows now a flexible and easy control because it was modeled on the daily conditions of occupation. It provides therefore a better comfort, improved quality workspaces and allows precise monitoring of consumption. It is now managed by a recognized specialist in its sector [Control Systems Management Board of BOUYGUES BATIMENT GRAND OUEST] and so is the guarantee of the continuity of different actions.

Urban environment

The building is located in the city center of Rouen, near the St Eloi church, in classified area. The implementation of the Marco Polo was done in accordance with the environment
in terms of views, sunlight and noise pollution. The building offers nice views on the Seine and on the «law» vegetated roofs. The U-shaped configuration of the building helps to protect some facades from the wind. Terraces and walkways are accessible to users at any time of the year.
The public transport (buses, metro) are all available within 200m.
Parking is marked on the ground to secure access for pedestrians and bicycles.

Reasons for participating in the competition(s)

Owner and occupant of Marco Polo building, the company Bouygues BATIMENT GRAND OUEST wanted to thrive in the long term its presence in the building while enhancing its expertise in the energy performance professions to control its environmental impact.

Looking for a third party investor to finance the restructuring and acquire the building, BOUYGUES BATIMENT GRAND OUEST relied on PFO2, SCPI from the PERIAL Group. The mobilization of funds required for the work was based on an operation of "sale and lease-back". This operation has led BOUYGUES BATIMENT GRAND OUEST to sell to PFO2 his building and remain tenant.
