	Building automation typically involves the automatic control of heating, ventilation and air conditioning systems, lighting, access control, energy management, fire alarms and other building services. This may involve the use of an electronic building management system (BMS). Commercial, industrial and residential buildings fitted with such systems are often called ‘smart buildings’ or intelligent buildings’.
