Ventilation rate, person and area
Ventilation rate, person and area
(OP)
Hello,
1- a 1000sq.ft of office space with 4 occupants needs [(5*4)+(1000*0.06)]= 80 cfm of outdoor air.
2- a 2000sq.ft of office space with 4 occupants needs [(5*4)+(2000*0.06)]= 140 cfm of outdoor air.
both spaces have the same height, same everything except the area.
I think the air in the 1000sq.ft space has more CO2 concentration than the air in the 2000sq.ft space. What do you think?

Are you sure about the number of occupants? 500 ft2 per person? Are they super CEOs or something?
IMC and ASHRAE also prescribes how many ft² per person you have to assume. This is to take into account potential changes, and avoid bad assumptions. Like in your case those may be people with a lot of visitors.
