Which of the following is a core feature of a building automation system (BAS)?

• A. It logs energy data only
• B. It provides centralized control of building systems with remote monitoring and fault detection
• C. It is for security only
• D. It replaces cybersecurity measures

Answer: (B)

Centralized control of building systems with remote monitoring and fault detection is the core capability of a building automation system. By integrating HVAC, lighting, sensors, and other systems into a single platform, it lets operators adjust settings, schedule operations, and view performance from one interface, even when not on site. The fault-detection aspect automatically flags anomalies—like unusual energy use or equipment drift—so maintenance can be proactive, reducing downtime and keeping occupants comfortable. While logging energy data is useful, BAS is much more than data collection: it actively manages and optimizes how the building runs. Security is important, but BAS serves broader purposes beyond security, and cybersecurity must be maintained rather than replaced to keep the system protected.
