I am currently working on a residential building. For LEED V2009, the requirement of the permanent entryway system should have 3m long in the primary direction of travel.

Hi everyone, 

1. Our project has a laundry room inside of an office space which is not intended for housekeeping activities, chemical storage, mixing, or disposal.

I am working on 2 University projects, both seeking LEED certification. Both buildings have loading docks with a back-of-house entry.

I have a laundry room in a building which has no interior doors to other inhabited interior spaces, only an exterior door and exterior windows.

Does anybody know wich option (roll out mats or permanent entryway systems ) is more efficient/clean for an hospital?
