From the OpenStudio SketchUp plugin:
Extensions > OpenStudio User Scripts > Add or Alter Model Elements...
Add New Thermal Zone For Spaces With No Thermal Zone
Rename Thermal Zones Based on Space Names
...which will rename the zones as "Thermal Zone: Space Name".
If you want to change the zone name prefix and are familiar with OpenStudio Measures you can alter the the RB file from #2, which can be found here on a Windows machine:
C:\Program Files\OpenStudio 1.14.0\Ruby\openstudio\sketchup_plugin\user_scripts\Alter or Add Model Elements
Rename_ThermalZones_Based_On_Space_Names.rb
# rename thermal zone based on first space with prefix added e.g. ThermalZone 203
if number_of_spaces > 0
new_name = "TZ: " + spaces_in_thermal_zone[0] + multi
thermal_zone.setName(new_name)
else
puts "#{thermal_zone.name.to_s} did not have any spaces, and will not be renamed."
end
Where "TZ: " is the prefix. Zone names can be identical to space names, but might cause issues such as calling the getModelObjectByName method on a model.
