The LEED Reference Guide states that entryway systems need to be on the interior of the building or in an interior vestibule. It is recommended that projects pursuing this credit with the intent of using an exterior entryway system (either permanent or rollout) consult the GBCI or your certification board via email to verify credit compliance. It is usually accepted that exterior walk-off systems are allowed if they are properly sheltered from weather; that would typically mean some kind of roof, but additional shelter may be warranted depending on local conditions.

Identify space requirements for entryway walk-off mats. Review the impact that the required ten-foot entryway systems will have on common areas, lobbies, and other interior spaces adjacent to building entries. Remember that the entryway systems have to be

Identify space requirements for entryway walk-off mats. Review the impact that the required ten-foot entryway systems will have on common areas, lobbies, and other interior spaces adjacent to building entries. Remember that the entryway systems have to be installed at all regularly used entrances from exterior spaces, including entrances from a covered parking garage into the building.

Refrigerants are not harmful to the environment until they are released into it. That’s most likely to occur during installation, maintenance, and removal. Hire a contractor that uses best-practice refrigerant management techniques to minimize leakage rates during operations and when installing new or removing old equipment.

Specify high-quality equipment with a dependably long lifespan. That way leakage is minimized at those times that carry the greatest risks; when the equipment is being installed or decommissioned. (For information about the service life of different types of HVAC equipment, see the 2007 ASHRAE Applications Handbook—HVAC Applications. See Resources.)
