What is natural ventilation defined as?

• A. Active air circulation through mechanical means
• B. Sealing off compartments for safety
• C. Opening accesses to allow fresh air exchange
• D. Limiting air flow to prevent smoke spread

Answer: (C)

Natural ventilation is defined as the process of allowing fresh air to circulate within a space by utilizing openings such as windows, doors, or vents to facilitate the exchange of indoor and outdoor air. This method relies on natural forces like wind pressure and thermal buoyancy to create airflow without the use of mechanical systems. By opening these accesses, buildings can reduce indoor pollutants, control temperature, and enhance comfort without the energy costs associated with mechanical ventilation systems. The focus on allowing fresh air exchange highlights the importance of creating a healthy indoor environment and the simplicity of natural ventilation as a passive strategy that harnesses environmental conditions to benefit occupants.
