Hi I am importing gbxml file for geometry in openstudio, while doing it, there is only one zone created, but in reality there are multiple zones, how can I create those zones, in the editor tab there is no option of doing that, ca someone guide me on how to do it?

Assuming the gbxml import preserves Spaces (e.g. surfaces, loads), in the OpenStudio Application (as suggested here):

+ thermal zone

  • first, add new zones in the "Thermal Zones" tab
  • (optional) edit them beforehand, e.g. rename, add thermostat schedules, sizing parameters
  • switch over to the "Spaces" tab (just above)
  • link (drag-and-drop) newly created thermal zones to the right spaces

This can be automated with an SDK-based script if the model holds hundreds of spaces. Hoping I understood your question correctly.

Thanks for the reply, the issues it is a 70 story building with more than 200 zones.

Understood. If the zoning strategy/logic can be clearly articulated (e.g. core vs south-facing vs north-facing, internal load density, story height), then 20 or 30 lines of an SDK-based script could automate the process (creating zones, linking spaces to zones). If the zoning strategy is instead quite unique (e.g. convoluted geometry, specialized facility), then you're left doing it by hand IMHO.
