Our Office building is ventilated with only 100% Outside Air Systems and thus there is no recirculation.

Table IEQc5-1 of the LEEDOnline form is asking for "isolated exhaust system areas", leading us to that question:
-- Our exhaust air ducts for copy rooms and laundry areas do combine at some point with exhaust air ducts from the office zones into a main single exhaust line directed to the outside.
Would that be considered as a designated/isolated exhaust system?

Thanks for your help!
