The aufbau principle states that electrons will fill lower energy levels before moving to higher energy orbitals, but the rules are all related. The aufbau principle takes into account the Pauli exclusion principle and Hund's rule to explain the building-up of electron configuration. You could think of it like this: the Pauli exclusion principle and Hund's rule must be fulfilled in order for the aufbau principle to apply.
