Increase Ventilation - Corridor

Hi, we intend to attempt this credit, but come across on our design that we does not have any dedicated FCU serving on this corridor. the corridor is a simple walkway for employees walk over to a customer lounge to meet up with client. the corridor is just 15 feet long. do i need to ensure this particular corridor have sufficient OA as to achieve this credit requirement.? the lobby or customer lounge connected by the walk way has sufficient OA (with a dedicated FCU serving this area) but by adding in the corridor SF, the whole required CFM increase. Please advice.
