The Materials and Resources Prerequisite, Facility Maintenance and Renovations Policy under LEED AP O+M V4.1 covers the materials or products that are used in the maintenance and renovation of a facility. This includes replacement carpet tiles, which are often part of facility renovations. Other items like refrigerators and automated scrubbing machines are not typically covered under this policy as they are considered equipment rather than materials used in maintenance and renovations. Janitorial paper purchases could be covered under the policy if they are part of the facility's maintenance operations.
