Start With One Floor
Measure it before and after.
A pilot block of guestroom FCUs, scheduled around occupancy, gives you the two numbers that settle this in your own building — airborne contamination and airflow at every fan speed. The floor trades the same night. No disruption, no case to take on faith.
