Hi Oscar,

One way to do it would be to assume a run-time for the Proposed Case which could depend on some estimates of the CO produced in the parking garage.  I know the Canadian standard is to use a run-time of 6 hours (2 morning, 2 mid-day and 2 evening) for ventilation control.

One thing to keep in mind for LEED is that you will need to demonstrate that CO control is not standard practice in your jurisdiction.  I know it's required by the building code here in Ontario, so it can't be claimed for credit.  

All the best,
