Chapter 4, Ventilation governs the ventilation of spaces intended to be what?

The correct choice, which indicates that ventilation governs spaces intended to be occupied, aligns with the fundamental purpose of ventilation systems. Proper ventilation is critical in occupied spaces to ensure a healthy indoor environment. It regulates air quality by introducing fresh air and expelling stale air, thus diluting airborne contaminants such as carbon dioxide, odors, and other pollutants that can accumulate when people are present.

In occupied spaces, ventilation contributes to comfort by controlling temperature and humidity levels, which can affect occupant health and productivity. Codes and standards for building ventilation are designed with occupant safety and well-being in mind, making it essential that these systems are designed and implemented to serve areas where people will be.

On the other hand, consideration for unoccupied spaces or those under construction is typically less rigorous, as ventilation needs differ significantly when the space is not being utilized. Additionally, temporarily closed spaces do not regularly require the same ventilation approach as those actively in use.
