Which areas must a project address to maintain good indoor air quality (IAQ)?

Increase artificial lighting
Remove contaminants from outdoor air
Install sound barriers
Change flooring materials

The correct answer is: Remove contaminants from outdoor air

Maintaining good indoor air quality (IAQ) is crucial for the health and comfort of building occupants. Addressing contaminants in outdoor air is an essential aspect of ensuring that the air entering a building is clean and free of pollutants. The process of removing these contaminants typically involves the use of air filtration systems and mechanical ventilation strategies designed to improve the quality of incoming air. This approach prevents outdoor pollutants, such as particulate matter, allergens, and volatile organic compounds, from entering the indoor environment, which can significantly enhance the overall air quality for occupants. While other options may influence the overall environment of a building, they do not directly correlate with the fundamental principles of improving IAQ. Increasing artificial lighting can impact visual comfort, but it does not address air quality issues. Installing sound barriers primarily targets noise reduction rather than air quality concerns. Changing flooring materials may have some relevance depending on the materials used, but it doesn't encompass the broader challenge of managing outdoor air contaminants. Focusing on the removal of contaminants from outdoor air directly contributes to the foundational goal of maintaining optimal indoor air quality.
