NC-2009 IEQp1:Minimum IAQ Performance

Exhuast fan and 62.1 compliance

If we use an exhuast fan for an office and have no clear location of OA intake, can we comply with 62.1? Assumed that the Ventilation Rate Procedure (with zone and system effectiveness) can be supported by an exhuast fan, adequately.

I dont see why not. So long as you can demonstrate how the air will enter the space and that it is clear of any contaminant sources.

I see somewhere in 62.1 mentioning the mandatory of "OA intake" which might conflict with exhuast ventilaiton. In exhuast ventilation, there is no clear intake location.
