Self-contained classroom pods = regularly used entrances?

Picture a University bldg. shaped to form a slot canyon to provide shaded access to the outdoors. Within the canyon, which includes doors to exit the courtyard, are a few small classroom pods. Does each classroom pod entrance require walk-off mats from the canyon courtyard? There is also a pod on the roof, accessed directly from internal stairs. But it has an exit door, that may be used for re-entry. We believe re-entry is not "regularly used."

Hi Joyce, I'm afraid that the classroom pods would require walk-off mats. I'm working on a factory project that has a cafeteria with exit doors out onto a patio. The patio itself is contained (fenced), meaning further egress from it isn't intended. We received Final Design Review comments last week from GBCI and they denied us this credit point. We may add walk off mats inside the cafeteria, TBD. I have read that placing part of the walk-off mat on the exterior of the door is allowed, provided it is protected from the elements and cleaned regularly. You may wish to explore this option if interior space is limited. Good luck. David

Note: carpet tile designed for walk-off mats is an acceptable solution, so you can provide an interior walk-off mat that is a better aesthetic and functional product than a grate, grill, or roll-out mat.
