To determine potential mold growth
To measure energy loss

The correct answer is: To determine potential mold growth

Comparing indoor relative humidity to outdoor levels is essential for determining potential mold growth because mold thrives in environments where humidity levels are elevated. Mold spores require moisture to germinate and proliferate, making humidity a critical factor in assessing mold risks. If the indoor relative humidity is significantly higher than that of the outdoors, it indicates a moisture problem that could lead to mold growth. High indoor humidity may also suggest inadequate ventilation, excessive moisture from sources like leaks or humidity-generating activities, or unbalanced HVAC systems. Thus, this comparison serves as an indicator for potential mold-related issues, leading to proactive measures in mold prevention or remediation. Understanding the differences in humidity levels allows mold assessment technicians to provide targeted recommendations to improve indoor air quality and reduce the likelihood of mold growth.
