You are correct that the sizing period simulations are the basis for the sizing calculations. Without a description of the HVAC system, it's hard to say for sure why the system isn't maintaining setpoint. Check the system description (especially setpoint managers and schedules) to make sure the system is controlling to the same supply temperatures specified in the sizing objects.
