Narrative:

We experienced a 'hydraulic G rsv low lvl' ECAM (electronic centralized aircraft monitor) during descent. We followed the ECAM SOP and secured the ptu (power transfer unit) off and the engine 1 green hydraulic pump off. The result was a loss of green (primary) hydraulics. After completing the ECAM and following up with the QRH for hydraulic G rsv low lvl we continued to landing. The gear successfully came down and normal flaps full configuration for landing. The captain made a smooth touchdown on the centerline and was able to maintain control on landing with reverser no 2.he was able to slow to taxi speed and gently clear the runway at the high speed taxiway and come to a complete stop using alternate brakes. Tower handed us over to the emergency response frequency and after about 5 minutes we were able to communicate with the emergency response crash recovery vehicles who met us at the taxiway. We shut down both engines after getting APU up and running and then had super tug tow us to our gate.

Title: A320 First Officer reported a normal landing followed the loss of the Green System hydraulic fluid.

Narrative: We experienced a 'HYD G RSV Low LVL' ECAM (Electronic Centralized Aircraft Monitor) during descent. We followed the ECAM SOP and secured the PTU (Power Transfer Unit) Off and the ENG 1 Green Hydraulic Pump off. The result was a loss of Green (primary) Hydraulics. After completing the ECAM and following up with the QRH for HYD G RSV Low LVL we continued to landing. The gear successfully came down and normal flaps full configuration for landing. The Captain made a smooth touchdown on the centerline and was able to maintain control on landing with Reverser No 2.He was able to slow to taxi speed and gently clear the runway at the high speed taxiway and come to a complete stop using alternate brakes.
