Natural ventilation plays a crucial role in interior design primarily because it helps control indoor air quality. By allowing fresh outdoor air to circulate within a space, natural ventilation can help dilute indoor pollutants, reduce the concentration of allergens, and eliminate stale air. This exchange of air enhances the respiratory health of occupants and contributes to overall comfort within the environment.

Incorporating natural ventilation into design not only fosters healthier living conditions but also aligns with sustainable design principles that favor the use of natural elements over mechanical systems. The overall design can feature strategically placed windows, vents, or openings that facilitate this airflow, optimizing the indoor environment’s quality.

The other options do not accurately reflect the benefits of natural ventilation. For instance, while natural ventilation can impact humidity levels, it is not primarily intended to increase humidity in spaces. Additionally, it indeed contributes to energy efficiency by reducing reliance on heating and air conditioning systems, while promoting the use of natural materials directly contradicts the advantages of natural ventilation, which is aimed at improving air quality rather than advocating for artificial materials.
