How to extract ACH results of naturally ventilated zones?

Hello,

I am using honeybee to perform a thermal comfort analysis of a naturally ventilated building model. I want to know how to extract the simulation results of air exchange per hour (ACH) using the airflow network (AFN) option in honeybee. I have already set up the construction sets, program types, internal mass, and natural ventilation parameters for my model. I have also run the Open Studio simulation successfully with the AFN option enabled.

However, I am not sure how to access the ACH results from the simulation output.How can I extract the ACH results from the honeybee simulation using the AFN option? Is there a specific component or formula that I need to use?

Thank you in advance for your assistance.
