Carre Seine
In the space of fifteen years, Issy-les-Moulineaux has become a leader in the field of HEQ in the inner suburbs of Western Paris.
This distinction strengthens its status as a new economic platform home to the headquarters of major French and international companies. At the same time, new residential neighbourhoods have sprung up promoting diversity, today’s urban “religion”. To maintain this position, for many years now this commune has been committed to a proactive policy marked in particular by the creation, in 2009, of an environmental quality charter for the buildings constructed in Issy-les-Moulineaux. Even more demanding than the charter required for low energy buildings (BBC), Isséo+ has been drawn up in a participatory manner. It offers construction sector players, planners and developers an innovative and pragmatic tool to maintain the environmental quality of collective residential housing, facilities and commercial properties.
This development is located in the mixed development zone (ZAC)stretching from the banks of the Seine in Issy-les-Moulineaux opposite Île Saint Germain up to the Jacques Henri Lartigue tramway station on the T2 line. The operation is part of the Val de Seine masterplan which aims to reclaim wasteland in this former industrial area in order to harmoniously link it with the city centre. This site is served by RER C train line and several underground lines (8/9/10/12) which are accessible via buses and footpaths. However, the T2 and RER C lines create a significant urban barrier which isolates this site from the rest of the city. Hence, the development on this islet of landscaped, pedestrian, and cycle areas (ground floor retail premises) running perpendicular to the Seine will open up this part of the city, where non-motorised transport will be a credible alternative to car travel, including for local journeys.
Isséo+ label, Carré en Seine demonstrates the use of unusual housing techniques to meet demanding HEQ and thermal regulation specifications (RT 2005/65kw/hr/m²/yr). Small in size, the distinctive character of these homes lies in their high environmental quality and the innovative use of outdoor spaces, which are detached from the façade to form zinc “boxes” oriented towards the views and sunlight.
This urban construction is made up of three buildings comprised of many distinct architectural elements. First, there are two buildings comprising 69 dwellings (BBC, NF, and HEQ) erected over 4,673m² between Quai de la Bataille de Stalingrad and Rue du Passeur de Boulogne. Secondly, there is a hotel residence with 175 rooms built over 6027m², the technical facilities of which are located in a dark brown brick tower on the 10th floor, a real landmark on Rue du Passeur de Boulogne.
Surrounding a shared patio, the three buildings provide soft stories and views of the Seine. Density is controlled by breathing spaces, which consist of the landscaped garden (650m²) in the heart of the development and the large area separating the hotel residence from the housing, connected, on the Seine side, via metal walkways. The concrete of the north façade of the tourist residence overlooking the Quai de la Bataille de Stalingrad has received a specific moulding treatment (“ bamboo” model) in order to signal entry into the new district, an important and defining element both during the day and night on the banks of the Seine.
90% of the housing is interconnected, dual aspect or duplex.
It is the fruit of a competition launched in 2009 on the design/construction method brought together by a developer, in this case Eiffage, 3rd group of French BTP (Construction and Public Works) and three proposed contractors. Out of the three competing architectural firms, Jean-Baptiste Pietri was chosen along with the landscape engineering firm Atelier Jours. During the competition stage, the Franck Boutté engineering firm was added to this team. The major challenge of this hyper-rational programme was to control density: those involved were asked, in effect, to develop 11,000m²on a plot of only 2500m² and to comply, moreover, with demanding HEQ specifications, particularly those drawn up by the engineering firm Tribu, Assistant Project Manager of the ZAC.
