Air flow rate that needs to be supplied according to ASHRAE 62.1 table 6.2.2.1 "Minimum Ventilation Rates in Breathing Zone" in order to maintain indoor comfort.

Cove.tool automatically calculates your whole building CFM air flow value. To enter a custom CFM, do the following. 

  • For ASHRAE/IECC compliance: Use building floor area (sqft or m2) and divide by occupation density (sqft/person or m2/person). Then take the results (occupation number) and multiply by the listed CFM value (CFM/person) from the above ASHRAE table. Calculation may be different for non-ASHRAE/IECC based projects.
