According to local codes, what is the minimum amount of outdoor ventilation air suggested per person in places without smoking?

The correct answer reflects the typical ventilation requirements set forth in various local building codes and guidelines. Specifically, a recommended minimum amount of outdoor ventilation air is often established to maintain indoor air quality, provide adequate fresh air, and reduce the potential buildup of indoor pollutants in occupancy areas.

For non-smoking environments, many guidelines and standards suggest around 8.5 cubic meters of outdoor air per hour per person. This amount strikes a balance between ensuring sufficient ventilation for comfort and health while being practical for building systems to achieve effectively.

In contrast, options that suggest lower air volumes may not provide enough fresh air to adequately dilute indoor contaminants, while higher figures could lead to unnecessary energy consumption or difficulty in maintaining comfortable indoor conditions. This reasoning aligns with industry standards aimed at promoting health and comfort through effective air exchange in various types of occupancy scenarios.
