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?

We have couple of projects where the HVAC system is being served by Chilled Beams and Radiant Cooling. I would like to know is there any specific method for carrying out building flush out with 100% DOS system.

There is no specific different method for going about a building flush out with 100% DOS. The only caveat is that typically a DOS system is between 20-50% of the size of a typically VAV system with min OA that would serve the same size project. As a result you may need to schedule more time in the construction schedule to finish the flush out over a typically VAV system capable of economizer. If the construction schedule is tight you can bring in temporary supplemental fans to speed up the flush out.
