Credit requirements seem to indicate that 10' long compliant mats are to be located at all "regularly used exterior entrances". Now, what do we need to do regarding connections to an existing building that is not part of the LEED project? We are trying to get a School Addition certified, and one of the points of entry (not the only one) to this addition is a door from the main corridor of the existing building. The existing building has mats in all its exterior entrances, but not as long as required by LEED. Do I still need to provide a 10' long mat between existing and new buildings? please take into account that this connection is purely through interior spaces.

I wouldn't think so. I have never seen them require a mat at an entry from an interior space. I would think this would hold true even if the interior space you are coming through is not LEED certified.

Well, they just did ask us that in the preliminary design review. It appears that we need to provide 10' long mats in all the interior connections to the existing building -OR- proof that all the entrances in the existing building (NOT part of leed project) have them. I have read the reference guide time and time again and was not able to find anywhere that we were required to do so. Some covered spaces were listed, like a parking garage, etc. but they are still inherently exterior spaces. Our case is totally different, entrance is through a pretty long central interior corridor, very far from any exterior entrances. Risk of contamination is minimal, yet we are required to provide the mats. We will need to add roll-out type ones; I will let you know how it goes. Thanks for your help.
