Building Automation Systems are interlinked, centralized, networks of software and hardware which control and monitor the environment in industrial, commercial, as well as institutional facilities. The BAS system ensures the safety, comfort of building occupants and operational performance of the entire facility.
These control systems are perfect for installing in the new building and it can even install the old buildings replacing the outdated control systems or as a renovation part.
Typically, such control systems are installed in new buildings or as part of a renovation where they replace an outdated control system.
The automation or control of buildings uses varied terms and you may have heard some of them such as:
– BCS (Building Control System), BACS (Building Automation and Control Systems) and BMS (Building Management System) — defined as Building Automation System.
– Controls— describes different types of devices that control processes or particular pieces of equipment.
– DDC (Direct Digital Control) —describes the modern devices and their communication method (software and hardware). Overall, DDC products form the automation system controlling different building systems.
– EMS (Energy Management System) — it gives emphasis on monitoring/metering but generally known as Building Automation System.
– Energy System and Management — hope it’s clear now.
– Intelligent (Smart) Building— equipped (a building) with a BAS.
What does “Controlled” mean?
Building Automation System begins with a great control of electrical, mechanical, and MEP (plumbing) system. For example, the HVAC system (heating, ventilation, and air-conditioning) is controlled and its other pieces of equipment like-
– RTUs (Roof-top Units)
– AHUs (Air Handling Units)
– HPUs (Heat Pump Units)
– FCUs (Fan Coil Units)
– VAVs (Variable Air Volume boxes)
Lighting control is very important for optimizing the performance of a building. The things that bring everything under a total automation system include:
– Power monitoring
– Keypad and card access
– CCTV (Close Circuit video)
– Fire alarm system
– Water and plumbing monitoring
Types of Control and Building Automation Systems
The control systems were air-based or pneumatic early days and the HVAC system is restricted by various aspects. The pneumatic devices generally include sensors, controllers, valves, actuators, regulators, and positioners. This pneumatic control systems are found in various metropolitan areas as these installations (large base) were basically established during the 1960s and 1970s.
In the 1980s, the electronic control devices (analog) became very popular. It provided higher precision and faster response compared to pneumatics. In the 1990s, DDC (digital control) gave the taste of true automation. And the open communication system made a revolution in the 2000s.
