CFM - Certified Facility Manager Technology Management 1 — Questions and Answers
Question 1: Which building automation system (BAS) protocol is most widely used for interoperability between HVAC, lighting, and other building systems from different manufacturers?
- Modbus RTU
- BACnet (Correct answer)
- LonWorks
- MQTT
Correct answer: BACnet
BACnet (Building Automation and Control Networks) is the ASHRAE/ANSI/ISO standard protocol specifically designed for building automation interoperability, enabling devices from different vendors to communicate on a common network.
Question 2: A facility manager is evaluating software that uses historical energy consumption data and machine learning to forecast future utility costs. This capability is best described as:
- Demand response management
- Energy Information Systems (EIS) with predictive analytics (Correct answer)
- Automated fault detection and diagnostics (AFDD)
- Real-time energy metering
Correct answer: Energy Information Systems (EIS) with predictive analytics
Energy Information Systems (EIS) with predictive analytics combine historical data with machine learning algorithms to model and forecast future energy consumption and costs, supporting budget planning and efficiency decisions.
Question 3: What is the primary purpose of an Integrated Workplace Management System (IWMS)?
- To replace the building automation system with a cloud-based alternative
- To consolidate facility management functions such as space, maintenance, real estate, and sustainability into a single platform (Correct answer)
- To provide cybersecurity monitoring for operational technology networks
- To automate procurement of maintenance parts and supplies
Correct answer: To consolidate facility management functions such as space, maintenance, real estate, and sustainability into a single platform
An IWMS integrates multiple FM disciplines — space management, maintenance management, real estate portfolio, capital project management, and sustainability — into one unified software platform, improving data consistency and operational efficiency.
Question 4: A facility manager notices that occupancy sensors are integrated with the HVAC and lighting systems so that spaces automatically adjust temperature and lighting based on real-time occupancy. This is an example of:
- Demand-controlled ventilation only
- A closed-loop control system using sensor feedback (Correct answer)
- Preventive maintenance scheduling
- A CMMS work order workflow
Correct answer: A closed-loop control system using sensor feedback
Closed-loop control systems use real-time sensor feedback (occupancy data) to automatically adjust system outputs (HVAC and lighting levels), continuously correcting system behavior based on measured conditions.
Question 5: Which technology standard governs the cybersecurity of industrial control systems and operational technology (OT) environments, including building automation systems?
- ISO 27001
- NIST SP 800-82 (Correct answer)
- OSHA 29 CFR 1910
- ASHRAE 62.1
Correct answer: NIST SP 800-82
NIST SP 800-82 (Guide to Industrial Control Systems Security) provides specific cybersecurity guidance for industrial control systems, SCADA, and operational technology environments such as building automation and control networks.
Question 6: A CFM is implementing a space utilization program using badge access data, Wi-Fi connection logs, and desk sensors to measure how often workspaces are actually occupied versus booked. What is the main benefit of this approach?
- It eliminates the need for a CMMS
- It enables data-driven decisions about space consolidation, redesign, or lease reductions (Correct answer)
- It replaces preventive maintenance scheduling with predictive algorithms
- It automates energy billing chargebacks to departments
Correct answer: It enables data-driven decisions about space consolidation, redesign, or lease reductions
Combining multiple passive data sources (badge, Wi-Fi, sensors) gives facility managers accurate actual utilization rates versus reservation data, enabling evidence-based decisions on right-sizing the portfolio, consolidating underused space, or renegotiating leases.
