Crawl Space Ventilation

[ssn61]

I am working on renovation of HVAC for a school in Dallas, Texas. This school is over 50 years old and crawl space is naturally ventilated. Does anyone know what the latest code requirements on crawl space ventilation are?

Typically 1 sf for each 150 sf of floor area.

Thanks for the reply Ron. Is this from IBC? Can you reference the section please?

It is right in IB - LOOK it up!!

Thanks MiketheEngineer for the friendly advice! Unfortunately I don't have a copy of the latest version.

1203.3.1 in IBC 2009.

I would recommend buying or borrowing a copy so you are comfortable with how it reads.
