1. Calculate the required airflow (CFM)
Calculate the building volume (width × length × height) and specify the required air-change rate to select adequate fan sizes and quantities for heat removal.
2. Plan the airflow direction
The source recommends placing exhaust fans in the direction of natural airflow, with intake openings on the opposite side so incoming air travels through the work area.
3. Avoid short-circuit airflow
Avoid placing intake openings too close to the exhaust fans. Otherwise, fresh air may be exhausted before circulating through the work area.
