Office ventilation rates
WebbIn their study, ventilation rates per person were varied between 3.8 and 15 cfm per person (1.8 and 7.2 L/s per person). With the lower ventilation rates, there were increases in intensity of headache, fatigue, sleepiness, and difficulty thinking clearly, but only some of the increases were statistically significant. WebbVentilation rate = (Minimum outside air flow rate *Occupancy) /Air change rate. For example, if the minimum outside air flow rate is 10 CFM per person and the occupancy of the space is 100 people, the ventilation rate would be 1000 CFM. If the air change rate is 4 times per hour, the minimum ventilation requirement would be 250 CFM.
