As far as I'm aware infiltration will not prorate the mechanical ventilation rate which would imply that they have no relationship.

DesignSpecification:OutdoorAir doesn't 'do' anything on it's own. It simply defines how much OA you want to be brought into a given space. Other objects such as Controller:MechanicalVentilation can reference DesignSpecification:OutdoorAir to determine what their minimum flow rates need to be.

Thank you for the reply, but forgive that I'm not the HVAC major. I used ideal loads air system in my project, and I have to set the design specification : outdoor air. whether you mean that this OA is arise the mechanical ventilation and will result in the change of space cooling and heating.
