Your comment in "Bird's Eye View" above states:
"Buildings with large numbers of identical rooms with separate ventilation zones—such as hotel rooms or apartment units—have been allowed to perform random sampling as an alternative approach in situations when the delivery of outside air—on an air-change-per-hour basis—and the materials in a ventilation zone are identical. Project teams should confirm with GBCI that this is still applicable in LEED 2009."
If our condo has 5 different unit "types", is it feasable to only sample 1 of each unit type? not exactly sure what "random" means.

They definitely handle this type of thing on sort of a case by case basis. Proposing sampling one of each unit type may be very well received, but it will likely depend on the number of units you have. I have never seen them accept sampling that accounts for less than 10-15% of the total number of units or square footage, so if one of each unit type is less than this percentage, you will likely need to do more. As far as random goes, if you let the testing agent pick which of each type of unit to sample instead of you directing him to a certain unit in particular you should be in pretty good shape.
