I am trying to add Zone HVAC Ideal Loads Air Systems in OpenStudio, but I have no idea, how to do this. I posted another similar question here, but I believe this question refers to Zone Equipment and not to air loops. By a lot of digging, I found that there are a bunch of awesome test .osm models (here), and I found a .osm file that includes Zone HVAC Ideal Loads Air Systems here.
You would think that you could add this kind of zone equipment via the library options on the right, but I do not see it anywhere. How can I add this zone equipment to my model?
