In the Ungerboeck, the event info contains the space assigned to it. There is no concept of a building in Ungerboeck. However, we assume that the top-level space hierarchy will be the building for the space. The buildings found will be stored as room groups in events2HVAC with the associated rooms as children to those groups.
If the buildings assigned in Events2HVAC aren’t what you expect, you can always change the room groups in Events2HVAC so that they make sense.
If any rooms are changed, deleted or added in Ungerboeck after you setup Events2HVAC, you will need to rebuild the room list in Events2HVAC so that the changes are seen.
