Which of the following is NOT typically considered part of occupant comfort?

• A. Thermal comfort
• B. Visual comfort
• C. IAQ
• D. Earthquake resilience

Answer: (D)

Occupant comfort is about how people experience and feel in the space on a daily basis. It includes thermal comfort (temperature and humidity), visual comfort (lighting levels and glare), and indoor air quality (how clean and fresh the air is). Earthquake resilience, however, is about how a building performs during and after seismic events—its structural safety, stability, and ability to protect occupants during an earthquake and recover afterward. It’s focused on safety and disaster performance rather than the everyday sensory experience of the space. So the option that does not belong to occupant comfort is earthquake resilience.
