What is the primary purpose of ventilation in buildings?
Correct!
Wrong!
Ventilation improves indoor air quality by removing pollutants and supplying fresh air to maintain a healthy environment.
Which ASHRAE standard provides guidelines for indoor air quality in commercial buildings?
Correct!
Wrong!
ASHRAE Standard 62.1 establishes ventilation and indoor air quality requirements to ensure occupant health and comfort.
What is a common indoor pollutant that ventilation systems help to mitigate?
Correct!
Wrong!
Carbon dioxide, volatile organic compounds (VOCs), and particulate matter are common pollutants that ventilation systems remove.
Why is proper air filtration important in HVAC systems?
Correct!
Wrong!
Air filtration removes airborne contaminants such as dust, pollen, and bacteria, improving indoor air quality and occupant health.
What is the main benefit of demand-controlled ventilation (DCV)?
Correct!
Wrong!
DCV optimizes ventilation rates by adjusting airflow based on occupancy levels, improving efficiency and air quality.
How does natural ventilation contribute to indoor air quality?
Correct!
Wrong!
Natural ventilation uses outdoor air to dilute indoor pollutants, reducing reliance on mechanical systems and improving air quality.
