double counting of airflow?

[JanghyunJK]

• came across while working on something else
• and unsure if it was intended
• but isn't this below double counting? so for like FCU DOAS, FCU airflow gets added to the zone_hvac_total_mass_flow_kg_s and DOAS airflow gets added to the air_system_total_mass_flow_kg_s. but that air from DOAS goes to FCUs. so I felt like this might be double counting.

total_building_avg_mass_flow_rate_kg_s = zone_hvac_total_mass_flow_kg_s + air_system_total_mass_flow_kg_s
