Bercy mechanical ventilation station

Construction of the Bercy mechanical ventilation station

Now that the worksite has been shut down and traffic has returned to normal on Bercy Street, we’re working on completing a few final tasks, mostly inside the MVS.

  • We are on the last steps of installing electromechanical equipment inside the MVS
  • We are doing finishing work
  • In the spring, we will finish the landscaping and install benches and garbage cans in the small square

The trailer next to our building will remain in the alley for another few weeks while we finish the interior work.

A mechanical ventilation station is an infrastructure located between two métro stations that is equipped with two fans designed to extract hot air from the métro network through inlets fitted with air vents. Ventilation stations built for the original métro network extract around 60,000 cubic feet of air per minute, while the new ventilation systems extract around 240,000 cubic feet per minute. Huge noise suppressors mitigate the noise from these fans to ensure quiet for residents living close to a ventilation station.

Mechanical ventilation stations serve three essential purposes:

Comfort ventilation
Regulates the ambient temperature and supplies fresh air for transit users by exchanging air from the outside with air inside the métro network.

Night-time ventilation
Ensures a supply of fresh air for night workers carrying out routine maintenance.

Emergency ventilation
In the event of an incident, controls smoke and provides a safe evacuation route for passengers via the nearest métro station and ensures unobstructed access for emergency first responders.

No. Essentially, a mechanical ventilation station exchanges the air inside the métro that transit users breathe with outside air, ensuring a constant supply of fresh air.

There are no contaminants in a mechanical ventilation station. Rainwater or snow falling into the ventilation shaft will be collected by the métro’s water-pumping system and released into the municipal sewage system, as is currently done throughout the métro network.
