back doors, garage/parking level entries, emergency exits, connections between concourses, and atrium entries.

While the prerequisite only requires entryway systems at primary exterior entrances within the LEED project scope of work, projects may benefit from installing entryway systems at all exterior entrances of the building.

ENTRYWAY SYSTEM LENGTH AND DESIGN There are no length requirements for the entryway systems, but it is highly recommended to utilize the best practice length of at least 10 feet (3 m.) in the primary direction of travel, which allows for approximately two full steps per shoe from an average person.

Design the entryway system to accommodate and withstand specific climate conditions. Areas with high precipitation, for example, may need more absorbent mats made with mold- and mildew-resistant materials. If using rollout mats, consider selecting ones that have a solid backing. A nonporous backing captures dirt and moisture and helps prevent contaminants from collecting underneath the mat.

Regular cleaning and maintenance will extend the integrity of the entryway system. Projects are encouraged to provide routine care for these systems, which is typically weekly.
