As a building operator, you oversee the operations of a building or facility to ensure that its electrical and mechanical equipment, as well as heating and cooling, are working properly. Your duties may include inspecting the building for safety hazards and regulation violations, performing repairs, and checking the facility’s ability to operate successfully. You may also supervise other employees. A career as a building operator typically requires a diploma or certification training program to gain hands-on experience in areas such as building science and energy efficiency. You may also need state certificates of fitness in facility components like interior fire alarms, sprinkler systems, and refrigeration to demonstrate your ability to handle these potentially dangerous materials. Additional qualifications include strong mechanical skills, attention to detail, and knowledge of industry regulations.
