FAQs about IEQc3.2 :

Is it possible for the flush-out start date to vary by ventilation zone?

Should a parking garage be included in a flush-out, if it is in a basement and not fully open to the outdoors?

Do the outdoor air minimum quantities have to be met for each individual space, or for the building square footage as a whole?

Do non-regularly occupied areas such as bathrooms and corridors have to be flushed-out?

For LEED NC addition projects, do existing non-renovated areas need to be flushed-out or tested?

For IAQ testing, how many sample points are necessary in non-mechanically ventilated spaces?

Can testing be done over various days?

I'm confused about the 11/1/2011 LEED addendum that removed the "1/25,000 SF or each contiguous area whichever is larger" language from the credit requirement. How do we determine the number of sampling locations for testing?

CI-2009 IEQc3.2:Construction IAQ Management Plan—Before Occupancy

Combining Option A and B

Can Options A and B be combined? Someof the floors are occupied and have met Option B testing requirements. But now the project schedule has changed and we're concerned that fast-tracking the other floors may result in testing failures with no time to re-test prior to occupancy. We can start a phased flush-out for the rest of the floors - but this means using both options to achieve the credit.

William, I am trying to think of the worst-case scenario here and I cannot see a logical reason why GBCI would deny this approach, provided you give a proper narrative explanation. Of course, they might reject it as not being an option (with some credits you are explicitly allowed to combine options, but not here)—let us know how you fare.

William, We have a project that, for slightly different circumstances, is an ideal candidate for a hybrid IAQ testing/flush-out approach. In this case, the project is comprised of a variety of ventilation systems/zones, some of which are well suited for a timely flush-out, whereas others are not. Due to the quantity of ventilation systems involved, exclusive use of IAQ testing would be a costly endeavor that the project team would prefer to avoid if possible. Have you received a ruling on your application of this method yet? We'd be curious to hear how it was received by the GBCI reviewer. Thanks in advance for any insight you can offer!
