In our osm model we want to define our climate zone using the ASHRAE climate zone values, so I have created the following ClimateZone object using this function in the OpenStudio SDK seen here.

Unfortunately this climate zone object causes our osm to crash and it seems to be something to do with the nze hvac measure. You can see the logs here.

This only happened when I changed the OS climate zone to the climate zone before:

Previously I was using the climate zone below and it worked:

Whats going on here, how can I fix this?

The measure wants the Climate Zone to be specified per the 2006 standard. I'll update it to take 2006 or 2013, but use 2006 for now.

# get the climate zone
climate_zone_obj = model.getClimateZones.getClimateZone("ASHRAE", 2006)
if climate_zone_obj.empty()
  runner.registerError("Please assign an ASHRAE climate zone to the model before running the measure.")
  return false
else
  climate_zone = "ASHRAE 169-2006-#{climate_zone_obj.value}"
end
