You are asking in the wrong Forum, my friend. This forum is for Refrigeration Engineers.

This is not really the place to look for answers. However, to be short:

You need ventilation 1.5 cfm/sq.ft. which is the IMC standard (International Mechanical Code)

You need to start ventilation when CO2 levels reach about 25 ppm. As a rule of thumb, you need a CO2 senser for every 2000 sq.ft. of basement parking garage.

The best would be to consult with your local Fire Authority and the corresponding by-laws in your area.

I wish I could be more helpfull, but I'm committed to my trade, Refrigeration!
