What is a common consequence of poor ventilation in buildings?

• A. Increased structural integrity
• B. Accumulation of indoor air pollutants and allergens
• C. Improved energy efficiency
• D. Enhanced indoor temperatures

Answer: (B)

A common consequence of poor ventilation in buildings is the accumulation of indoor air pollutants and allergens. When ventilation is insufficient, contaminants from various sources, such as dust, mold, volatile organic compounds (VOCs), and bacteria, remain trapped indoors. Over time, this buildup can lead to a decline in indoor air quality, potentially causing health issues for occupants, such as respiratory problems, allergies, and other illnesses. Proper ventilation is essential for maintaining a healthy indoor environment, as it helps to dilute and remove these harmful pollutants, allowing for fresh air circulation and better overall air quality.
