The building management system (BMS) is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipment. It is usually made up of software and hardware that interact with each other to receive data from various building sensors, make decisions based on pre-programmed rules, and execute actions accordingly.
A BMS typically consists of three main components:
1. A network of controllers that collect data from sensors and actuators, make decisions based on pre-programmed rules, and execute commands;
2. A human machine interface (HMI) that allows operators to monitor the system, change settings, and override automated controls; and
3. A database that stores all data collected by the system for analysis and reporting purposes.
The primary purpose of a BMS is to keep the occupants of a building safe, comfortable, and productive by controlling the environment within it. In commercial buildings, this often means maintaining indoor air quality at acceptable levels, providing adequate lighting and temperature control, keeping the building secure, and reducing energy consumption.
