They work in commercial buildings, hospitals, and large facilities. The role suits skilled, knowledgeable, practical people who understand building systems deeply, can operate and fix complex equipment, respond to problems and emergencies, and combine technical expertise with the responsibility of keeping a large building's vital systems running safely and efficiently.
