Which factor is crucial in preventing mold growth in buildings?

1. High temperatures

2. Regular inspections

3. Low humidity

4. Using plant-based materials

The correct answer is: Low humidity

Maintaining low humidity levels is crucial in preventing mold growth in buildings because mold thrives in environments where moisture is abundant. When humidity levels exceed 60%, the likelihood of mold spores germinating and proliferating increases significantly. Keeping humidity low creates an unfavorable environment for mold, as it limits the available moisture that mold needs to grow. Regular inspections play a key role in identifying potential issues before they escalate, but without addressing moisture levels, inspections alone cannot effectively prevent mold. High temperatures and using plant-based materials may impact certain aspects of mold growth but do not address the primary factor, which is moisture control. Therefore, emphasizing low humidity as the primary preventive measure directly targets the root cause of mold proliferation.
