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?
I don’t think that EnergyPlus has an AFN output in terms of ACH but you can look through all available outputs for your model with the HB Read Result Dictionary. There are a lot of outputs related to the AFN that you can request from E+ using the HB Custom Simulation Output component and the bring into Grasshopper with the HB Read Custom Result component.
At a minimum, you will be able to get the air flows through each of the Apertures in the AFN.
