DesignSpecification:OutdoorAir not being set by OpenStudio
I have noticed in hourly reports and the HTML EnergyPlus Outdoor Air Summary Report that thermal zones were not receiving ventilation air volumes as defined in the OS:DesignSpecification:OutdoorAir objects. I exported the IDF file from my OpenStudio model and all of the 'Design Specification Outdoor Air Object Name' fields are blank when opened in the IDF editor.
It appears OpenStudio (1.9.0) does not set the 'Design Specification Outdoor Air Object Name' for the AirTerminal:SingleDuct:VAV:Reheat object. This excerpt from the E+ Input/Output reference suggests this field is required for the AirTerminal to deliver the proper amount of ventilation...
I am not using demand controlled ventilation and the total airflow to zones is routinely under the volume of outdoor air defined.
How does OpenStudio implement the DesignSpec:OA to ensure the AirTerminal provides minimum ventilation at all times? Are there other approaches to consider or am I missing something here?
This question builds upon this previous question
