Can credit 3.2 be earned from a re-test post occupancy?

Bob, curious if anyone else has experience here, but I would assume you can't earn the credit, based on the clear requirement that the flush-out be conducted pre-occupancy (in order to protect occupants from contaminants).Although it may not qualify you for the credit, it sounds like a flush-out may be a good idea, though.

I may have commented on this before. Tristan is correct. Testing and retesting must occur before occupancy. If you are pursuing the testing method you are risking the credit if you don't budget time for retesting. In the LEED reference guide it says: "If a test sample exceeds the maximum concentration level, flush out the space by increasing the rate of outside air. While the credit requirements do not prescribe the duration of the flush-out, those responsible for testing should make an evaluation based on the contaminate, its concentration, and the potential source... Resample and confirm compliance BEFORE allowing occupancy."

Robert, good luck! I think the main point is that occupants are currently or will be exposed to contaminants, and nothing you can do now can prevent that. There is a alternative for an accelerated flush-out during occupancy, but it seems even too late for that.

Just to confirm, we had a re-test six days after occupancy and the credit was rejected upon preliminary review. Technical advice reads "this credit requires that the testing is COMPLETE AND COMPLIANT [my caps] prior to occupancy. Please confirm the date of occupancy and the dates of the testing process." I don't see any way out of this one.
