A building management system (BMS), also known as a building automation system (BAS), monitors and manages mechanical, electrical and electromechanical areas. It includes a wide range of services such as electricity, heating, ventilation, air conditioning, physical access control, pumping stations, elevators, lighting and security and surveillance systems.

Depending on the specific application and configuration, a BMS may be referred to as a building automation system (BAS), building management and control system (BMCS), and building energy management system (BEMS).

The BMS or Building Systems Management is essential because it improves the management of reports and information, ensuring quality, informed decisions, better performance and reduced energy consumption. Additionally, it can be installed as a standalone application that monitors and manages a wide range of building services across multiple web platforms and protocols.
