Permanent Entryway systems < 10 feet long

George, I would be curious if anyone else has had a different experience, but I very much doubt that you could earn this credit with a system less than 10 feet.The only possibility I can think of is that if you are using LEED-CS v2.0 (an earlier version), the requirement is only for 6 feet.

From your description it would seem one recourse might be to include the entryway mat flooring into the elevator, assuming the combined depth would be 10' (and would USGBC count to the middle or to the back of the elevator - anybody's guess). Also - the elevators might not be the only way into the building - the path to stairs or a first floor room would have to be covered. Another option would be to get the city to accept a small portion of a recessed mat on the city sidewalk, so the total was 10'.
