Which indicators would prompt a BE team to update IAQ assessments?

• A. Increased energy usage
• B. New office equipment or furnishings, observed odors, or moisture issues
• C. Change in furniture color
• D. None of the above

Answer: (B)

When IAQ assessments should be updated, it’s because events or changes can introduce new pollutants, alter sources, or affect ventilation. Introducing new office equipment or furnishings can outgas VOCs and other chemicals from plastics, finishes, adhesives, or fabrics, directly changing the indoor air composition and prompting a reassessment of pollutant levels and ventilation adequacy. Observed odors point to the presence of contaminants or inadequate dilution, signaling a need to re-evaluate IAQ conditions. Moisture issues raise the risk of mold and microbial contamination, which can dramatically impact air quality and health, making an update essential. Energy usage alone doesn’t necessarily indicate a change in IAQ, and a mere change in furniture color has no IAQ relevance. Hence, the most appropriate trigger is the combination of new equipment or furnishings, odors, or moisture problems.
