What are the implications of inadequate ACH on indoor air quality and occupant health?

Inadequate ACH can lead to poor indoor air quality, which can cause discomfort, fatigue, and even health problems for occupants. In extreme cases, inadequate ventilation can result in the buildup of airborne pollutants, such as carbon dioxide, volatile organic compounds (VOCs), and particulate matter, which can exacerbate respiratory issues and other health conditions.
