Which occupant health benefits are associated with green architecture?

• A. Improved air quality, thermal comfort, natural light, acoustic comfort, and access to outdoor spaces
• B. Decreased filtration and ventilation
• C. Increased HVAC energy consumption
• D. Reduced daylight availability

Answer: (A)

Green architecture improves occupant health by enhancing indoor environmental quality, including clean air, comfortable temperatures, ample daylight, pleasant acoustic conditions, and access to outdoor spaces. When ventilation and filtration are well designed, indoor air stays cleaner and drier pollutants, which supports respiratory health and comfort. Thermal comfort prevents overheating or chill, reducing fatigue and stress. Natural light supports circadian rhythms, mood, and productivity, while good acoustic design minimizes noise distractions and stress. Access to outdoor spaces encourages physical activity, stress reduction, and connection with nature, all benefiting well-being.

The best choice lists all these health-supporting factors together, capturing the full range of occupant benefits. The other options describe drawbacks or trade-offs—such as reduced filtration and ventilation, higher energy use, or less daylight—which do not provide health benefits and can actually harm occupant well-being.
