The project concerns the rehabilitation of 2 buildings, of 102 dwellings in total, located Avenue de l'Europe in Sèvres.
It is an energy renovation project in the heart of the city of ceramics, which houses the workshops of the prestigious Manufacture Nationale de Sèvres and the National Museum of Ceramics, an area that is today the subject an ambitious development project.
An ambitious project that conflicts with the conventional architecture of social housing in the "Glorious Thirty" (1946-1975) sad and austere, demonstrating that it is possible to reconcile thermal performance, solution to asbestos problem, improvement of the living environment and innovation.
The goal of this renovation is to reduce the consumption of heating, domestic hot water, ventilation and auxiliaries to pass from the label F to C.
But that's not all, it is imperative to encapsulate asbestos present in the facade following a procedure consistent with the legislation in force on busy site (waste management, protection of companions etc ...).
The guiding ideas : Improve the energy performance of the residence while bringing color and relief. The construction site is still in the architectural environment of the city of Sèvres.
Technical constraints: Installation of 3 different types of cladding + classic thermal insulation on each facade. Regulatory constraint: presence of asbestos on lighters
The two buildings composing this co-ownership having different energetic performances, we will present here the data concerning the building 21, which is the most exemplary.
Sustainable development approach of the project owner
Decrease the heating consumption, hot water, ventilation and auxiliaries to pass the label of energy consumption from F to C. This renovation allowed in particular:
- Exterior insulation made of expanded polystyrene graphite
- Metal louvers in thermo-lacquered aluminum + cladding and framing of zinc berries
- The replacement of the boiler room
Architectural description
The buildings are constructed of reinforced concrete, with slab system, posts / beams and concrete sails. Access to the buildings is via ramps and stairs from the street to the ground level. This level corresponds to the high level of the base (roof terraces) which forms the massive base of the two buildings. This base is about 2,40 m above the lowest point of the street. The height is variable depending on the position of the building. The entrances are located on the respective forecourt of the buildings. The base of the forecourt of building No. 21 contains businesses.
Building users opinion
Very satisfied with the improvements made
If you had to do it again?
We would do the same procedure again.

Reasons for participating in the competition(s)
?L'idée directrice de cette opération était d'améliorer la performance énergétique de la résidence tout en apportant relief et couleur dans l'environnement architectural de la ville de Sèvres.
Pour ce faire, SPEBI a du effectuer ce chantier de rénovation énergétique avec des équipes spécialistes de l' ITE d'une part et du bardage d’autre part.
