The fourth floor of the Val Fleuri medical-social establishment was completely transformed. A former conference room, which was installed on a part of the roof, was demolished to make room for a complete new floor. The purpose of the project was to increase the capacity of accommodation in single rooms without increasing the number of residents and thus improve the resident´s living environment.

Our office was involved from the project design stage to the construction management stage of the heating, ventilation and regulation systems, with the aim of obtaining the Minergie label for this fourth-floor extension.


For the purpose of achieving the energy objectives of the Minergie label for this project, the following technologies were analysed, sized and subsequently implemented:

  • double-flow mechanical ventilation.
  • ventilation in the kitchen/cafeteria.
  • refrigeration chambers with condensate heat recovery for DHW pre-heating.
  • the refurbishment of the boiler room.
