Dear all,
Our project is a big mall, with the roof being utilized as restaurants, play area, a cinema complex, a green vegetated area, and some technical areas.
Accordingly, this area will be maintained and cleaned on a daily basis. In addition, the roof will be accessed from the floor below only, and hence can confidently be considered as a space within the mall with no connections to the outside.
My question is: Can we exclude the roof entrances from the "Indoor Chemical & Pollutant Source Control" credit? It is not physically feasible to install permanent entryway systems on the entrances between the open roof and the closed mall portion (cinema complex & escalator's lobby).
I believe that we can exclude permanent entryways. Any suggestions?
Many thanks!

I would say this is a gray area and it will be up to you to make your best argument to the reviewers that you shouldn't have to include entryway mats there.It is outdoor space, and subject to dust, sand, pollen, animal incursion, and other things that create "pollutants" in outdoor spaces.Think of it this way—would LEED allow you to skip the entryway for the front door just because your staff sweep the sidewalk once per day? I very much doubt it.That said, I do think you have a point and could argue it, it's just by no means a sure thing.

Your graphic above says the walk-off mats are 6' long, but the text here, and the LEED text, says the walk-off mats must be 10' long. Just checking.

Yes, the graphic is intended to illustrate the type of documentation to provide. The actual requirement changed from 6 feet to 10 feet with the introduction of LEED 2009.

John, I think there is a consensus on LEEDuser (see the NC IEQc5 forum, if I remember right) that you can hat a mat that's at least partially outdoors if it's weather protected. Or it could be broken up in other ways, too, if there is 10 feet in the direction of travel.

Has anyone tried a partially indoor partially outdoor mat in 2009? This new phrasing does seem to trump previous CIRs and rulings, so I would be very cautious about trying the half and half method in 2009 without a CIR.

Allison, I am wondering if you had any response about partially indoor partially outdoor, due to building circunstances I need to do this strategy.

I have not heard anything new on 2009 yet- I'll take another look at LEED Interpretations in the next day or two. If that is the only strategy you can do- it's definitely worth submitting that way and hoping for the best.
