The air conditioning system

The project foresees a maximum crowding of 2,716 people.

Comfort and air quality of this prestigious installation are ensured by 3 Clivet centrifugal chillers controlled by inverter to modulate their capacity according to the water temperature in order to guarantee maximum comfort with the lowest energy consumption and by 8 air handling units in two sections with double enthalpy rotary recuperator AQX by Clivet.

The system is completed with an evaporative tower serving the chillers, while the transfer of heat and cold is entrusted to chilled beams and fan coils.

The main technical rooms for the thermo-mechanical systems are located at:

  • Second basement floor: refrigeration unit, room for input of remote heating, pump rooms, water station, room for input of ground water
  • First basement floor: UTA lobby and conference room, fire service head quarter
