Recently, automation has become one of the most heard topics in almost every industry. The concept of automation has spread its roots deep in day to day lives of humans. Automation consists of applications ranging from a household thermostat controlling a boiler to a massive industrial control system with tens of thousands of input measurements and output control signals. In control complexity, it can have a spectrum ranging from simple on-off control to multi-variable high-level algorithms.
What is an Automation System?
Automation is the technology by which a procedure of process is done with minimal human assistance or interference. Automation or automatic control is the utilization of various control systems for operating equipment such as processes in factories, machinery, boilers, and heat treating ovens, turning on telephone networks, steering, and stabilization of ships, aircraft, and other applications, and vehicles with minimal or reduced human intervention.
In the simplest form of an automatic control loop, a controller compares a measured or observed value of a process with a desired set value and processes the resulting error signal to transform some input to the process, in such a way that the process remains at its desired set point despite various disturbances. This closed-loop control is an application of negative feedback to a system. The mathematical foundation of control theory was laid in the 18th century and developed swiftly in the 20th century.
Explaining Building Automation
Building automation is the automatic centralized control of a building's following aspects:
HVAC (Heating, Ventilation, and Air conditioning)
Heating, ventilation, and air conditioning (HVAC) is the technology designed for indoor and vehicular environmental comfort. Its major goal is to offer thermal comfort and acceptable indoor air quality. HVAC system design is a sub-discipline of mechanical engineering. The concept is based on the principles of thermodynamics, fluid mechanics along with heat transfer.
HVAC is a crucial aspect of residential structures/buildings such as single-family homes, apartment buildings, hotels, and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, vehicles such as cars, trains, airplanes, ships, and submarines, and in marine environments. The HVAC system is used to regulate healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
Lighting or illumination is defined as the deliberate utilization of light to generate practical or aesthetic effects. Lighting consists of the utilization of both artificial light sources such as lamps and light fixtures.
In the fields of physical security and information security, access control (AC) is defined as the selective constraint to access to a place or other resource while access management describes the process as a whole. Some consider the act of accessing might mean consuming, entering, or using. Permission to access a resource is known as authorization.
A security alarm is a system engineered to spot and detect intrusion or invasion– unauthorized entry – into a building or other areas such as school or home. Security alarms are utilized in residential, industrial, commercial, and military properties as a precautionary measure against burglary (theft) or property damage, as well as personal protection against intruders. Security alarms in residential areas exhibit a correlation with decreased theft. Similarly, car alarms help protect vehicles and their contents. Prisons also utilize security systems for the control of inmates.
All of the above aspects are controlled by the Building Automation System (BAS). The major purpose of building automation are improved occupant comfort, efficient and effective operation of building systems, reduction in energy consumption, increased security, reduced operating costs, historical performance documentation, remote access/control/operation, the improved life cycle of equipment, and utilities related to it.
A Building Automation System has two major components: software and hardware. Generally, the software program is configured hierarchically, can be proprietary, utilizing protocols such as C-Bus, Profibus, and so on. Vendors are also making a BAS that combines the utilization of Internet protocols and open standards such as DeviceNet, SOAP, XML, BACnet, LonWorks, and Modbus.
Following is a list of systems that can be controlled or monitored by a Building Automation System:
- Illumination (lighting) control
- Electric power control
- Heating, ventilation, and air conditioning
- Security and observation

Four Latest Trends in Building Automation System
IP Products are in Massive Demand in the Marketplace
All of the key players in the building automation space have introduced Internet Protocol (IP)-based systems, according to Scott Cochrane, president, and CEO of Cochrane Supply and Engineering. In an IP-based building automation system, every device on the network has its IP address, similar to the way computers are networked.
Master Systems Integrators Bridge Facilities Management and IT
The latest trade is getting into facilities management from the security system industry. Master systems integrators are specially designed for building and maintaining data plumbing, or the way cloud computing systems are linked. The job is a combination of IT and facilities and is the natural generation of facilities management strategies that substantially depend on networked devices.
Staffing Needs to Change Constantly
The rise of master systems integrators explains why staffing decisions are so important and at such high stakes. Facilities professionals require substantial knowledge, not only in building systems, but in engineering, computer science, and other areas that are vital for controlling, monitoring, and managing today’s buildings. Part of finding these people is making sure they know facilities management exists, Cochrane says.
Facilities Improvements Actively Drive Revenue
Facilities departments have historically had an undeserved reputation as a cost center. However, facilities professionals in today’s world are utilizing automation and digital tools to directly benefit the bottom line.
Market Scenario for Building Automation System
