Residence Sarrazins, Lille, France.
Scope of Renovation
The Residence Sarrazins Project aims to renovate and improve the energy performance of its assets to optimize the comfort of tenants and reduce rental charges/energy bills in order to fight against energy poverty.
Renovation will be implemented within the framework of a European consortium by adapting new technologies, reducing the duration of work done on an occupied site and optimizing the building’s energy, indoor air quality and comfort monitoring. Reducing energy consumption and lowering maintenance costs are the main objectives of this renovation project.
