Once the ribbon had been cut, the elected representatives, developers, residents and other locals followed a brass band through the new eco-neighbourhood to reach the central square, where speeches were made, and the Marianne d’Or awarded. Special events attracted young and old alike: sheep trotted through the streets; environment-friendly clowns performed shows and guided history tours were on offer. Visitors also enjoyed workshops on farmyard animals, pony rides, information stands on geothermal heating and vacuum waste collection.
FROM AN OLD 19TH CENTURY MILITARY SITE TO A NEW NEIGHBOURHOOD HERALDING THE CITY OF THE FUTURE
The story began in 2000, when the French Ministry of Defence decided to decommission the Fort at Issy-les-Moulineaux. The local semi-public enterprise SEMADS decided to launch a competition to create value from the site. It was Bouygues Immobilier, together with Architecture Studio, who won the competition with its redevelopment proposal.
More than 10 years were required for the project’s major steps, including withdrawal of defence personnel from the site, obtaining a building permit and purchasing the site from the French state. Work started in December 2010, with completion scheduled for the beginning of 2014. This new living space, on the heights overlooking Paris, includes 18 buildings with BBC low-energy, providing 1,623 apartments including 300 social housing units. The development will accommodate a total of 3,600 people. Bouygues Immobilier developed half the residential complexes: Le Belvédère, with Architecture Studio, Le Visio, with 2A architects, Or Natura, with Guerin and Pedroza and Le O’ Paris, with Wilmotte & Associés.
THE CITY’S FIRST GEOTHERMAL HEATING NETWORK
The two geothermal wells, bored 750 metres into the earth’s surface to exploit the natural heat from the Albien aquifer (present underneath part of the Paris basin), will cover 78% of the energy requirements of apartments, shops, schools and public buildings in the Fort. This main heating network will provide hot water and heating, while a moderate-temperature water loop (28°C) will both heat and cool homes through heat pumps located at the foot of the buildings.
Dalkia, by using the principle of a geothermal doublet, will ensure that not a single cubic metre of water is lost, assuring the aquifer remains at a constant level.
THE FIRST PNEUMATIC WASTE COLLECTION NETWORK FOR HOUSEHOLDS WITH A MOBILE VACUUM SYSTEM FOR TRUCKS
It’s a first for France: pneumatic waste collection for households is carried out by “vacuum trucks”. Waste disposed of at collection points is temporarily stored in underground containers with capacity of 3 to 8m3 before being evacuated three times a week by a truck which plugs into vacuum points on the outside of the Fort. This innovative method of waste collection, already well developed in Sweden, offers numerous advantages for residents and the local authority. In particular, it optimises health and safety, eliminates fire hazards and reduces sound and olfactory pollution.
CONNECTED HOMES TO SIMPLIFY DAILY LIFE
Nicknamed “the Digital Fort”, the eco-neighbourhood is connected to the fibre-optic networks of the different internet access providers. Residents can manage their daily energy consumption more effectively and control lighting, heat and window blinds via a touch-screen at the entrance of their homes. The screen, which can be controlled remotely from a mobile phone, also doubles up as a video interphone and a device for obtaining live information (weather, traffic, news, etc.).
AT THE HEART OF THE FIRST SMART GRID PILOT PROJECT IN FRANCE
By the end of 2013, the residential district of Fort d’Issy will be connected to IssyGrid, a unique project in Greater Paris, which is a forerunner of positive-energy neighbourhoods of the future. This pilot programme is based on a triple logic — consuming better, less, and at the right time — while incorporating new uses such as the integration of locally-produced energy and the optimisation of energy management and uses (offices, housing, shops, public amenities) at neighbourhood level. It is also connected to the public grid which enables stored energy to be distributed. Finally, it aims to smooth peaks in consumption, traditionally a source of increased costs, and a higher carbon footprint.
