A Design Day defines the outside temperatures that are used to size your HVAC equipment's heating and cooling capacity.
Design Specification Outdoor Air (DSOA) defines the ventilation requirements for a zone.
Without a DSOA object, the ideal loads system is just recirculating the zone air and heating/cooling it to meet setpoint. You need a DSOA to account for energy associated with heating/cooling the outside air needed to for ventilation requirements.
