LEED v4 describes to install a permanent entryway systems at least 10 feet (3 meters) long in the primary direction of travel, to capture dirt and particulates entering the building at regularly used exterior entrances.
If the lenght (or the total width) of the pavement - that is perpendicular to the functional entry - is not 3 meters long, but for example 1,2 meters long. How can this requirement be feasible?
Can for example a part of this 3 meter be situated within the buiding?
Thank you in advanced.
