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?

Due to phasing plan the contractor will need to run AHU prior to completion of another phase of the project. If the area under construction is completely isolated from the area that has the flush out can we phase the flush outs over time to accomodate construction schedule or should we go for option 2 for the flushout and do it once all of the building is complete.

Is your AHU serving both areas? Can you phase the flushing by AHU? Testing prior to occupancy is likely an easier route. Are they doing any testing for ICRA?
