100% OA VAVs

We are remodeling two floors of a high-rise office tower. A 100% OA VAV introduces OA into the mechanical room for each floor where it is mixed with return air. An AHU in each mechanical room distributes the mixed air to the floor using a VAV system. With this arrangement, I want to confirm that installing an air flow monitor on the two OA VAVs (or simply showing that the fan is "on" per LIR #2099) and installing CO2 sensors in all densely occupied spaces fulfill the monitoring requirements of this credit.
