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.

Our project is pursuing Option 1 Path 2 - Flush During Early Occupancy. Do filters need to be replaced after the flush, or only after construction as part of IEQc3.1?

We have couple of projects where the HVAC system is being served by Chilled Beams and Radiant Cooling.

I would appreciate advice on the number of sampling locations needed for LEED Testing per IEQ Credit 3.2 Option 2 in mid-rise Apartment buildings. We follow the sampling rules for commercial build

Due to phasing plan the contractor will need to run AHU prior to completion of another phase of the project.

Hello, In the reference guide, it is written that for "Option 2 Air Testing", the test must be conducted after construction ends and within 14 days following occupancy.

Do we have to document flush-out somehow for the credit compliance? Is any report or declaration needed?

Can the Owner or GC do the IAQ test themselves ie be responsible for setting the test can and chain of custody to the lab?
