Hi
I am trying to model an existing Lab buildng with 16ACH actual ventilation rate. the height of the floor to ceiling is 15ft, the area is 35556 SF and about 100 people are working in the building.

How can I calculate CFM per person. The numbers I am getting is really high and is not even close to ahrae 62.1

Here is what I did for calculation

CFM/person = 16 (ach) x 35556 SF x 15ft / 60 / 100person
