SMILE's involvement in this project

Tangible help with funding
Actions to increase the visibility of your project

Previously an industrial HQ, the “La Marseillaise” building was completely restored to create a smart building with 39 social housing apartments.


The renovation was designed to require no fossil fuel energy so as to greatly reduce carbon emissions during its lifetime.

The building is equipped with hybrid solar panels which produce a proportion of the electricity and hot water requirements.


The building improvements along with the different power systems implemented should reduce the energy costs of users by 30%.

Added value of the project : 


  • A project featuring energy innovation in the framework of building renovation.
  • Allocation of accommodation with optimised energy management to a homogenous and clearly identified group (young workers).


Start date : March 2017.
