FAQs about IEQc3.5 :

How often do entryway systems need to be cleaned?

Can we clean entryway mats in-house, or do they need to be sent to a “professional” cleaning service?

We have a loading dock and an attached underground garage. Both of these areas have access into the building interior. Do we need to have entryway systems for either of them?

Do the ten-foot mats need to be one continuous mat?

Can an entryway system be split up so that part is located outside and the remainder of the required ten feet is located inside?

We already have a carpeted lobby that extends further than ten feet in all directions from the building entrance. Does this count as a compliant entryway system? Our cleaning staff vacuums and performs restorative cleaning frequently to this area.

We don’t have enough space for ten feet of mats. What can we do to earn this credit?

recessed walk off mat

We are specifying a recessed walk off mat for the building in the vestibule (8' long). I remember that if the walk off mat is 10', a point is granted. Do you know if the walk of mat needs to be recessed, or can we add a loose floor mat just inside the vestibule so the total length would be 8' + 2'? Or does the mat have to be recessed. Thanks!

Hi Bomin, you can do a combination of mat types as long as the total length is 10 feet in the direction of travel.
