Narrative:
The aircraft inadvertently pressurized below landing level; and we inadvertently landed with approx 2.5 psi differential pressure; following an ECAM status message at around 500 ft. It took a while to realize what had happened; and being on a short approach I landed. Following the landing; the outflow valve opened and the pressure equalized. Write up made in the logbook. The aircraft was operated with system 1 in the auto mode; and we could not figure out why this happened. System 1 pressure controller in the usual auto mode was being used with ZZZ as a landing airport in the FMC. We couldn't figure out why this happened. We didn't catch this until we received the ECAM status message because this trip has an extremely long duty day especially when factoring in the drive to work during rush hour in the morning.
