FAQs about IEQc3.2 :

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?

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?

Your approach will depends on your system's means of providing ventilation air. You probably have a dedicated outside air system (DOAS) or natural ventilation to provide ventilation to the space (VRV systems are typically only re circulation units). If your ventilation system isn't large enough to flush out the space in a timely matter, you may want to rent temporary fans to bring in outside air for the flush out.

If the site is located near the sea beach and the humidity level is high, then what should be our approch to do the flush out as temporary fan can not control the humidity levels also the humidity may affect the paints and furnitures as well ? Please suggest.

You'd probably want to rely on your DOAS to provide you flush out in that case. It will take you longer than if your system was a traditional VAV system with Economizer. You might consider the testing method if time is an issue.
