CFM CFM - Certified Facility Manager Human Factors and Ergonomics 2 — Questions and Answers
Question 1: What is the primary goal of ergonomics in workplace facility design?
- To maximize the number of workstations per square foot
- To design work environments and equipment that fit the physical and cognitive needs of the human user, reducing injury and improving performance (Correct answer)
- To reduce furniture procurement costs
- To standardize all workstations to a single design
Correct answer: To design work environments and equipment that fit the physical and cognitive needs of the human user, reducing injury and improving performance
Ergonomics fits the workplace to the worker, preventing musculoskeletal injuries and improving productivity and satisfaction.
Ergonomics applies knowledge of human anatomy, biomechanics, and cognitive psychology to design workplaces, equipment, and processes that match human capabilities and limitations. In facility management, this translates to proper workstation height and monitor placement, appropriate seating, and lighting.
Question 2: What is activity-based working (ABW) and how does it affect space planning?
- A model where each employee is permanently assigned to a dedicated workstation
- A workplace model where employees choose their work setting based on the type of task they are performing, reducing assigned seating (Correct answer)
- A performance management system tied to physical activity requirements
- A scheduling system for booking conference rooms
Correct answer: A workplace model where employees choose their work setting based on the type of task they are performing, reducing assigned seating
ABW provides a variety of work settings matched to task types rather than individual ownership.
Activity-based working removes assigned seating and provides a portfolio of work settings designed for different activities: open collaboration spaces, quiet focus rooms, phone booths, casual lounges, and formal meeting rooms. ABW typically reduces total space footprint.
Question 3: What does indoor air quality (IAQ) encompass, and why does it matter for human factors?
- The aesthetic appeal of interior finishes and materials
- The concentration of pollutants, temperature, humidity, and ventilation adequacy in indoor spaces, affecting occupant health and cognitive performance (Correct answer)
- The exterior air pollution levels affecting the building facade
- Only the presence of CO2 in the air
Correct answer: The concentration of pollutants, temperature, humidity, and ventilation adequacy in indoor spaces, affecting occupant health and cognitive performance
IAQ directly affects occupant health, comfort, absenteeism, and cognitive function - all critical human factors outcomes.
Indoor air quality encompasses volatile organic compounds from building materials, CO2 from occupants, particulate matter, temperature, relative humidity, and ventilation adequacy. Poor IAQ is linked to Sick Building Syndrome, increased absenteeism, and measurable reductions in cognitive function.
Question 4: What is the recommended illuminance range for general office work according to lighting standards?
- 50-100 lux
- 200-300 lux
- 300-500 lux (Correct answer)
- 800-1000 lux
Correct answer: 300-500 lux
IESNA and similar standards recommend approximately 300-500 lux for general office tasks, balancing visual comfort and energy use.
The Illuminating Engineering Society of North America (IESNA) recommends approximately 300-500 lux for general office tasks such as reading and computer work. Lower levels cause eye strain and fatigue; excessive levels also cause discomfort.
Question 5: What is thermal comfort and what ASHRAE standard governs it in commercial buildings?
- The visual appeal of the building thermal mass construction; governed by LEED standards
- The condition in which occupants express satisfaction with the thermal environment; governed by ASHRAE Standard 55 (Correct answer)
- The insulation rating of exterior walls; governed by energy codes
- The minimum temperature for outdoor workers; governed by OSHA standards
Correct answer: The condition in which occupants express satisfaction with the thermal environment; governed by ASHRAE Standard 55
ASHRAE 55 defines the conditions for thermal comfort using parameters including temperature, humidity, air speed, and metabolic rate.
Thermal comfort is defined by ASHRAE Standard 55 as the condition of mind that expresses satisfaction with the thermal environment. It is influenced by six factors: air temperature, radiant temperature, air speed, humidity, clothing insulation, and metabolic rate.
Question 6: How does biophilic design in facility management affect occupant wellbeing?
- It reduces energy consumption by eliminating artificial lighting
- It incorporates natural elements such as plants, daylight, water, and natural materials into the built environment, reducing stress and improving productivity (Correct answer)
- It focuses exclusively on outdoor spaces and is irrelevant indoors
- It is a decorative trend with no measurable health outcomes
Correct answer: It incorporates natural elements such as plants, daylight, water, and natural materials into the built environment, reducing stress and improving productivity
Biophilic design leverages humans innate connection to nature to improve mental health, satisfaction, and cognitive performance.
Biophilic design is grounded in the theory that humans have an evolutionary connection to nature affecting health and wellbeing. Research demonstrates that workplaces with plants, daylight access, views of nature, and natural materials reduce stress, lower blood pressure, and improve satisfaction and productivity.
