Under Guidance, above step-by-step add:
At this time the additional inorganic contaminants and volatile organic compounds are not included in the human experience score. For a more comprehensive indoor air quality evaluation, projects are encouraged to include all or some of these additional contaminants in their measurements. An additional point under the Innovation credit is available for projects that include two additional contaminants.

Under step-by-step:
add new paragraph:
Complete steps 1-4 as applicable. For this prerequisite, at least one of the three components of the Human Experience score (occupants satisfaction score, CO2 score, or TVOC score) must be pursued. Projects are encouraged to pursue all three components.

Step 1. Conduct an occupant satisfaction survey
Replace "transportation survey" with "occupant comfort survey."

Step 2. Achieve required response rate from the survey
Remove "Figure 1 in" from first sentence.

Step 3. Conduct an indoor air quality evaluation for the project
Add two paragraphs at the end:
The project team may use any measurement method capable of measuring CO2 and/or TVOC and use their best judgement when determining the number of sampling locations, and frequency and duration of testing. Laboratory-based test methods for TVOC are recommended but not required. If desired, the measurement methods and testing approaches outlined in following related LEED credits may be used: LEED v4.1 or LEED v4 BD+C credit Indoor Air Assessment, LEED 2009 BD+C credit Construction Indoor Air Quality Management Plan – Before Occupancy, and/or LEED v4 O+M Performance Based Indoor Air Assessment in Existing Buildings.

For TVOC, measurements must be provided in µg/m3. Use correction factors and/or conversion factors applicable to the instrument being used when converting from ppm to µg/m3 and note any assumptions in the evaluation report.

Under Required Documentation replace second bullet with:

Indoor air quality evaluation report, including narrative explaining how test locations were determined, dates, times, and results of each test, and measurement methods. If TVOC readings were taken in other units (such as ppm), include calculation details with any conversion/correction factors used.
