When temporary outdoor air ventilation is needed, what is the suggested CFM rating of fresh air per person?

The guideline for the suggested CFM (cubic feet per minute) rating of fresh air per person indicates that, in situations where temporary outdoor air ventilation is required, providing 15 cfm per person is an effective standard. This amount of fresh air helps ensure adequate dilution of indoor contaminants and pollutants, contributing to a safer and more comfortable environment.

The 15 cfm rate is based on balance—enough to provide significant ventilation without being excessive. It supports healthy indoor air quality during various environmental conditions and minimizes potential discomfort or health risks associated with inadequate fresh air supply. This standard is often cited in various industry guidelines and best practices regarding air quality and ventilation requirements.
