Fume hood & Isolated Exhaust Requirement

Our client has a fume hood in one of their laboratories but it is not within an enclosed room all to itself. It is within the larger open laboratory space, thus it wouldn't meet any of the separation methods as defined in IEQc5 nor would it have an isolated exhaust system. Is the fume hood itself considered an enclosure? Thanks

The fume hood alone does not provide the required enclosure for LEED. You may be able to argue that the laboratory space as a whole is separated, depending on the occupancy within the space. You would need to enclosed the whole space with full height walls and self-closing doors.
