Which structural factors can contribute to mold proliferation in buildings?

The selection highlights critical structural factors that can lead to mold proliferation in buildings. Mold thrives in environments that provide sufficient moisture and lack proper airflow. Poor drainage can result in water accumulation, creating the perfect conditions for mold growth. Similarly, inadequate ventilation restricts air movement, allowing moisture to build up in confined spaces. Furthermore, materials that retain moisture, such as certain types of wood or insulation, create conducive environments for mold to flourish. Together, these factors significantly increase the likelihood of mold issues in a building.

The other options, while they may touch on aspects related to building integrity, do not adequately address the conditions that directly contribute to mold growth. For example, adequate ventilation and non-porous materials help mitigate mold growth rather than promote it, making them less relevant in this context. Understanding how these structural factors directly influence moisture retention and airflow is essential for effective mold assessment and remediation.
