FAQs about IEQc3.2 :

Should we install furniture and furnishings before IAQ testing or flushout?

The air temperature and/or relative humidity went out of the credit requirement specifications for a portion of the flush-out. What do we do? Can we extend the flush-out for the equivalent amount of time to make up for it?

I've seen a lot of comments and guidance regarding Option 2 for air quality testing in residential applications, however no guidance on Option 1. Is it possible to choose a flush-out and comply with this credit point in a multi-family residential building? If so, is Path 2 for a phased flush-out an option for this project type? If so, then my final question is: when should the daily flush begin/end? Guidance says daily flush-out should "begin three hours before occupancy and continue until the end of occupancy for the day"... how does that apply to a project where occupancy is 24/7? Thank you for your assistance!

I also have a question regarding this credit. Could an NC 2009 multi-family project utilize the LEED Homes flush-out method for this credit? In Homes, you'd flush-out for 48 hours with existing exhaust fans and open windows. Assuming commercial areas are minimal, ours are about 8% of total area, those are excluded as I understand it. Has anyone gotten this through when using NC BD&C 2009? Even if we do need to account for flush-out of the limited commercial areas, that could be accomplished with temporary equipment if necessary.

Hi Teresa, did you get a response to your question? I am the same position now and would love some guidance. Its a multifamily building with 55 units along with common areas. Is a flush out feasible? Thank you! Courtney
