A building management system (BMS) is a computer-based control system installed in buildings that monitors and controls a facility’s mechanical and electrical equipment, such as heating, ventilation, and air conditioning (HVAC), lighting, and power systems. The goal of a BMS is to improve the energy efficiency, comfort, and safety of a building and reduce operating costs..

A BMS typically consists of a central control system that is connected to various sensors and actuators located throughout the building. The control system collects data from the sensors and uses this data to adjust the operation of the building’s systems and equipment in real time.

IT infrastructure and devices like servers, storage systems, and networks use Simple Network Management Protocol (SNMP) to communicate with each other (i.e., collecting, organizing, and modifying information). Conversely, building management systems communicate through protocol layers.
