Requirements for the IEQc2 Low Emitting Materials credit in LEED v4.1
Select one of the following two options, to be implemented after construction ends and the building has been completely cleaned. All interior finishes, such as millwork, doors, paint, carpet, acoustic tiles, and movable furnishings (e.g., workstations, partitions), must be installed, and major VOC punch list items must be finished. The options cannot be combined.
Option 1. Flush-Out (1 point)
Path 1. Before Occupancy
Path 2. During Occupancy
Option 2. Air Testing (1-2 points)
After construction ends and before occupancy, but under ventilation conditions typical for occupancy, conduct baseline IAQ testing in occupied spaces for the contaminants listed in each path.
Path 1. Particulate Matter and Inorganic Gases (1 point)
Path 2. Volatile Organic Compounds (1 point)
Long story short - flush out your building for 1 point OR test for particulate matter, ozone, and carbon monoxide for 1 point AND/OR a bunch of VOCs for a second point.
