How can cyber-attacks and physical faults be detected and differentiated in building energy systems?

What is it about?

•A flexible HIL framework to emulate faults and attacks in building energy systems. •Energy performance, controller dynamics and network traffic are real-time monitored. •A joint classification framework to differentiate physical faults and cyber-attacks. •Real-time HIL experiments were conducted to validate the threat detection algorithms.

Why is it important?

Modern smart buildings are steering the building industry towards open communication technologies. The increased connectivity and accessibility could lead to more cyber-attacks in smart buildings. On the other hand, physical faults may have similar adverse impacts as those from cyber-attacks on building energy systems, such as occupant discomfort, energy wastage, and equipment downtime. Therefore, smart buildings suffer from both cyber-attacks and physical faults. There is an urgent need for a framework to detect cyber-attacks and physical faults in building energy systems.
