2009 IMC / Spay and Neuter Clinic / Animal Area 425 sq ft
2009 IMC Table 403.3 requires 7.5 CFM per person and .18 CFM per sq ft.
5 persons @ 7.5 = 37.5 CFM
425 sq ft @ .18 = 76.5 CFM
Total = 114 CFM
My question is the last column of the Table. It requires .9 CFM per sq ft for an exhaust airflow rate.
425 sq ft x .9 = 382.5 CFM.
How does the 114 CFM calculated above relate to the 382.5 CFM for the exhaust airflow rate?
Do you exhaust at 382.5 CFM and only need to bring in 114 CFM outdoor air, the rest can be recirculated?
