Chirag, there's also an area-based component for hotel rooms at 0.06 cfm/sf, which should be added to the people-based component. At the default density 10 people per 1000 sf, this does equate to 11 cfm/person. Note that you may end up providing more ventilation to balance exhaust through the restroom in a hotel suite. Could you point out the reference for 30% increased ventilation? This is an optional LEED credit, but not required for basic ASHRAE 62 compliance. You're right that in some environments, bringing in additional OA is not desired. The base ASHRAE 62 rates are calibrated to typical CO2 generation from a person, so you generally don't need to worry about the actual CO2 level in a hotel room.
