Facility management is the professional discipline responsible for ensuring the functionality, safety, and efficiency of built environments. It encompasses building maintenance, space management, security, energy management, and occupant support services. Modern facility management integrates smart technology to monitor and optimise building operations in real time. Smart locker systems are a key facility management tool in corporate environments, enabling automated parcel reception, IT asset distribution, and key management without dedicated staff.
