Workspace opens to exterior and interior

We have a project that includes a workshop/studio space. This space will be used to construct small boats and other projects related to the organization's purpose which is marine environmental studies. The shop opens directly to the outdoors and to the interior (main education spaces) as well. As the shop is a "dirty" environment to begin with, we are not providing a mat from the exterior to the shop but will place a mat at the entrance from the shop to the classroom. The classroom also opens directly to the exterior as well as having the entrance to the shop. In another LEED comment, a contributor mentions walk-off mat carpet tiles. For our small project, it might make sense to install these "walk-off tiles" throughout the classroom space for aesthetic as well as practical reasons. Will this work and what sort of cleaning protocol would be required?
