What measurement can be checked to assess the potential for mold growth in a building?

Temperature
Carbon dioxide levels
Humidity
Light levels

The correct answer is: Humidity

Humidity is a critical factor in assessing the potential for mold growth in a building. Mold thrives in environments where humidity levels exceed 60%, as moisture is a fundamental requirement for its growth. High humidity creates conditions that are conducive to mold development, especially in areas that are poorly ventilated or where water damage has occurred. Temperature also plays a role, but it is not enough on its own to directly assess the potential for mold growth. While carbon dioxide levels can indicate building occupancy and can be related to indoor air quality, they do not provide definitive information about moisture and mold growth potential. Light levels, while important for other environmental considerations, have less direct impact on mold growth compared to humidity. Therefore, monitoring humidity levels is essential to prevent and manage mold issues effectively.
