Why would fresh air be introduced into an occupied residential structure?

To reduce humidity levels
To create a neutral pressure within the building
To improve heating effectiveness
To enhance air conditioning efficiency

The correct answer is: To create a neutral pressure within the building

Introducing fresh air into an occupied residential structure primarily serves to create a neutral pressure within the building. Neutral pressure is essential for maintaining balanced air exchange and ensuring that air does not flow in unwanted directions, such as into or out of the building through unintentional leaks. Maintaining a neutral pressure helps to improve indoor air quality by preventing the intrusion of outdoor pollutants and allergens while ensuring that any stale air is effectively expelled. The correct answer reflects a fundamental principle in building ventilation, which aims to provide a healthy and comfortable indoor environment. It prevents issues such as backdrafting of combustion appliances and helps to avoid excessive humidity or temperature imbalances inside the home. Although there are other advantages to introducing fresh air, such as reducing humidity levels, improving heating effectiveness, or enhancing air conditioning efficiency, the key focus here is on achieving a neutral pressure to support overall indoor air management.
