[Equest-users] cfm/person

[David Griffin]

CFM/person is given in ASHRAE 62.1 Table 6-1.

Two values are given in the table which affect your eQUEST input:


1)    CFM/person

2)    CFM/SF

The combination of the two values is your minimum OA – see Equation 6-1 of ASHRAE 62.1.

Therefore, your eQUEST input should go something like this:

((#LR(“SPACE”, “NUMBER-OF-PEOPLE”)*([CFM/PERSON])) + (#LR(“SPACE”, “AREA”)*([CFM/SF])))/ (#LR(“SPACE”, “AREA”)

Refer to ASHRAE 62.1 Table 6 for [CFM/PERSON] and [CFM/SF] values.

I hope this helps with your question. If anything is unclear, I’m sure the forum will clarify.

Thanks,
