Why is proper ventilation crucial in buildings?

Proper ventilation is essential in buildings because it helps maintain air quality and prevents moisture buildup. Adequate ventilation ensures that fresh air circulates throughout the space, which is vital for diluting indoor air pollutants, reducing humidity levels, and preventing the growth of mold and mildew. If air quality is compromised, occupants may experience health issues such as respiratory problems or allergies. Additionally, moisture buildup can lead to structural damage and create an environment conducive to pests. Therefore, proper ventilation directly contributes to a healthier living or working environment by ensuring that air remains clean and moisture is effectively managed.
