Question-and-Answer Resource for the Building Energy Modeling Community

If you select to have your zones modeled with ideal air loads in OpenStudio, at runtime OpenStudio will add in ZoneHVAC:IdealLoadsAirSystem objects to your zones, but most of the fields for the objects will be left blank. One of those blank fields is the Design Specification Outdoor Air Object Name which tells ideal air loads what ventilation rate to use.
You need to use an EnergyPlus measure to link your Design Specification Outdoor Air definitions in your spaces/spacetypes with the field in the Ideal Loads Air System object.
The Ideal Loads Options measure on BCL will do that for you and will also optionally include all the output variables you may want.

One of those blank fields is the Design Specification Outdoor Air Object Name which tells ideal air loads what ventilation rate to use.use. So the default is to assume no ventilation.

The Ideal Loads Options measure on BCL will do that for you and will also optionally include all the output variables you may want.
