Good morning all! We are currently working on a dining facility with vestibules at the two main points of entry. However, each vestibule measures just over 5'x5' and contains a recessed entryway system that encompasses the entire vestibule space. Has anyone had any success achieving IEQc5's entryway system requirement with this condition? It seems like I've read that you can achieve that requirement if your system spans from wall to wall in that space but I'm unable to locate it at this time. We are going to include a narrative explaining our position and how we are attempting to comply with this credit. However, I wanted to reach out to my fellow LEED Users for additional advice. Thanks so much!

Hi Amari, it seems your condition as described isn't in compliance. The reference guide states "...at least 10 feet long in the primary direction of travel...". If the design cannot be changed to meet this 10-ft distance in each vestibule, then I would have a carpet service company contracted to place 5-foot long carpets immediately after each vestibule, in the building interior. You could add 5 feet of exterior recessed mat systems, but they would need to be protected from the elements, and this may not be practical for several reasons.
If it makes you feel any better I've faced this situation before. The architect was a LEED AP and knew we were pursuing this credit. So frustrating!
Good luck. David

Thanks so much David, I figured that would be the case but wanted to see if anyone else had experience in this matter. The credit terminology seems misleading. They state that if you can provide information that you meet the credit intent, then your condition will be evaluated on a case by case basis. However, I have been unable to locate a case that didn't require the full 10 feet. Thank you for your response and the advice!

David's answer is your safest bet. Here is an interpretation that addresses splitting up the 10' or rationalizing an exception. However, any time you attempt an exception you are taking a risk.
