The minimum fresh air ventilation requirement for commercial spaces varies based on occupancy types, and ASHRAE 62.1 provides the detailed specifications needed for each type of occupancy. This standard outlines how different spaces, such as offices, gyms, and restaurants, have distinct ventilation needs based on factors like the number of occupants and the activities performed in the space.

Understanding these specific requirements is crucial for ensuring indoor air quality and occupant health. Proper ventilation considers not just the volume of air but also the quality and appropriateness for the space's usage. Therefore, consulting ASHRAE 62.1 is essential for those involved in the design, construction, and operation of commercial buildings to ensure compliance and promote a safe and comfortable environment.

Other choices suggest a one-size-fits-all approach or reference local codes as the sole determinant, which does not capture the nuanced requirements outlined in industry standards. Hence, relying on ASHRAE 62.1 allows for tailored strategies that reflect actual usage rather than generalizations.
