I have a four story project where we are doing IAQ testing in phases because of a tight schedule. All workstations and new furniture will be installed prior to the testing of each floor. However I've recently been informed that the occupants of the building are planning to re-use furniture that they are currently using at another location. And this furniture will be moved over as the occupants move-in, not prior.

As I understand it, all movable furniture has to be installed before IAQ testing. But LEED does not distinguish between new and re-used for this credit. Can anyone provide any further insight, because as I read the credit, to achieve Option 2 ALL furniture has to be installed.
