The DesignSpecification:OutdoorAir object in EnergyPlus applies the occupancy schedule fractions to the design Outdoor Air Flow per Person (cfm/person), so the required hourly minimum outdoor air rate during the simulation is less than the design specification. This turns the DesignSpecification:OutdoorAir into a variation of a demand control ventilation. How can one specify the Outdoor Air Flow per Person inputs in the DesignSpecification:OutdoorAir while maintaining fixed outdoor air flow rates during occupied periods of the hourly simulation?
