Building Automation System (BAS)
The ultimate goal of modern building automation is to facilitate total autonomous control of all of its systems.
With little no human input, automation aims to take care of the entire range of building services from HVAC to fire systems to lighting and climate control, all controlled and monitored from a single central control system.
When a building is controlled completely in this way, it’s referred to as a Building Automation System (BAS), with its core responsibilities being to maintain a comfortable internal climate, use lights efficiently and to monitor systems for outages and fluctuations in performance. When done correctly, this concept can be scaled up to control huge office block and large plant operations.
Whilst there is an initial cost involved in implementing the necessary systems and IoT hardware needed to achieve building automation, it is typically self-financed via the savings enjoyed in energy usage, preemptive maintenance and reduced insurance premiums. Residential and commercial buildings employing a BAS are often aptly described as being “Intelligent” or “smart” and will involve the installation of numerous sensors, smart devices and an IoT gateway.
The Internet of Things (IoT) hardware used when implementing a BAS are many and varied, depending on the building and what it’s being used for, but most will typically include the following:
- BAS controllers, which fall under 3 distinct categories; PLCs (programmable logic controllers); Network/system controllers and Terminal controllers, which are tailor made computers with both output and input capabilities. They come in a variety of shapes and sizes and allow adjustments to be made via the various sub network slave IoT devices.
- Air Handlers, which are used to adjust air temperature to the required level and maintain internal air quality by mixing it with fresh, external air.
- Chilled water systems, which use chilled water to cooling building spaces.
- Hot water systems, which heat the air handlers, as well providing domestic hot water supplies.
- Sensors, which are spread across the entire building and used to collect data needed by the various devices to make heating and lighting system adjustment calculations
Ultimately, the automation of buildings is a good thing for both building owners and the environment they sit in. The concept of Nearly Zero Energy Buildings (NZEBs) is becoming the construction industry standard and it’s only possible by employing sustainable design, an integral part of which is building automation. It’s a concept that is most certainly here to stay.
