Required outdoor airflow depends on the applicable building code, occupancy, floor area, room use, and the ventilation design standard used for the project.
A suitable ERV should be selected according to the required outdoor airflow and the system's delivered airflow at the actual duct resistance,not simply its maximum advertised airflow.
For project selection, consider the number of occupants, room-by-room air distribution, exhaust requirements, and the intended operating schedule.
