You can easliy check by yourself.
Let's say you have a 10-story building. All floors have the same layout. Each floor has one zone wih 100m2. The total floor area of the building is 100 * 10 = 1000m2.
Multiplier: 10
DesignSpecification:OutdoorAir: Flow/Zone, 0.1m3/s
Then, the total outdoor air flow rate for the zone with multiplier (i.e. the whole building) is 0.1m3/s * Multiplier 10 = 1m3/s
If you set DesignSpecification:OutdoorAir: Flow/Area, 0.001m3/s-m2, the total outdoor air flow rate for the zone with multiplier (i.e. the whole building) is 0.001m3/s-m2 * 100m2/Zone(without multiplier) * Multiplier 10 = 1m3/s
Multiplier is multiplied by DesignSpecification:OutdoorAir you input. Please input the outdoor air flow rate before multiplied in DesignSpecification:OutdoorAir.
