What is a building environmental systems operator?

Building Environmental Systems Operators are professionals responsible for the operation, maintenance, and monitoring of building systems that control indoor environments. This includes heating, ventilation, air conditioning (HVAC), refrigeration, and sometimes lighting and energy management systems. They ensure that buildings are comfortable, safe, and energy-efficient by troubleshooting issues, performing scheduled maintenance, and optimizing system performance. These operators often work in commercial, institutional, or residential buildings and may be required to hold specific certifications depending on the region.
