Underground Garage Ventilation

[kodzak1981]

Hello...Could someone help me on underground garage ventilation. I need some standards that I can use for my calculation. I've found that a lot of calculations are made acc. to DIN 18232, but I don't have that DIN...Can someone guide to some website for this DIN or eve better if someone have this DIN...Or some samples of calculations of this kind.

Thanks in advance

We use the IMC 2003, and it requires the system to be capable to exhaust 1.5 cfm/sf.

knowledge is power

Canadian Building Code calls for 0.75 cfm / sqft... and those fans hardly ever run. I can't imagine how much run time a fan system sized at 1.5 cfm / sqft would run.

I would base my CFM on whatever regulation is applicable to your situation but also I would double check my CFM with the NIOSH permissible exposure CO, NOx CO2 and total particulate levels.
