A Building Automation System (BAS) is a computer-based automation system that controls and monitors the building’s engineering services. This will typically cover mechanical, electrical and hydraulic services including ventilation, air-conditioning, heating, fire alarms, lifts and lighting systems.
By adopting a modern and properly designed and commissioned BAS, energy consumption will be reduced by 10 to 20 percent in an average building. In some buildings such as research laboratories the savings in energy can be far higher.
A conventional system tells what action needs to be taken, like a dashboard on a car, whereas tomorrow’s buildings being planned today will provide better insight into opportunities to improve performance outcomes.
Building automation, when designed properly, can contribute to improving indoor air quality (IAQ) which directly impacts occupant health and well-being. We spend 90% of our time indoors and according to the World Green Building Council, IAQ can contribute increases in productivity of 8 to 11 per cent.
When planning building automation systems consider the follow two issues:
Bigger Does Not Mean Better. There is a limit to how big a BAS can grow. At a certain point, it will become unwieldy, hard to manage and more prone to human error and breakdown. So as a system grows bigger, it makes sense to divide it into smaller systems and establish different levels of autonomy.
Rubbish In – Rubbish Out. Sensors do degrade and can turn your air-conditioning and ventilation system into an operational nightmare. Deployed with next-generation intelligent sensors, buildings of the future will constantly scan and rebalance for the greatest efficiency and effectiveness.
