Final answer:
The LEED rating system that has recertification is the LEED for Building Operations and Maintenance (LEED O+M), ensuring continual sustainability and efficiency performance of buildings.
Step-by-step explanation:
The Leadership in Energy and Environmental Design (LEED) rating system that includes recertification is the LEED for Building Operations and Maintenance (LEED O+M). This particular rating system allows for the continuous improvement of a building's performance over its operational life. The LEED recertification process helps to ensure that a building maintains and potentially improves upon its sustainability and efficiency standards initially met when the building first became LEED certified.
Recertification is important as it keeps the building up-to-date with the latest sustainability standards and encourages ongoing commitment to the environmental performance of the building. LEED recertification can be done through the LEED Dynamic Plaque which provides a live scoring of the building's performance or the traditional certification methods which are snapshots in time.
