I'm reading the Input Output Reference Manual for v9.5 and v9.6. For DesignSpecification:OutdoorAir objects, one of the outdoor air method is ProportionalControlBasedOnOccupancySchedule. However, none of the following fields that define the outdoor air flow, i.e. Outdoor Air Flow per Person, Outdoor Air Flow per Zone Floor Area, Outdoor Air Flow per Zone, Outdoor Air Flow Changes per Hour, is used when ProportionalControlBasedOnOccupancySchedule is selected according to the reference text.

And when I select this method in my model, the hourly output ventilation rate does not follow the occupancy schedule either.

I'm wondering when using this method, how is the outdoor air flow defined? How is the "proportioned"?

I use this method in Controller:MechanicalVentilation, "System Outdoor Air Method" field, without DCV enabled and economizer, night cycle, etc.
