What is the minimum ventilation airflow rate required per square foot for enclosed parking garage floor areas?

The minimum ventilation airflow rate required for enclosed parking garage floor areas has been established to ensure proper air quality and the safe removal of harmful gases and exhaust fumes produced by vehicles. The correct answer of 0.75 cfm (cubic feet per minute) per square foot is based on guidelines and standards set by industry organizations and building codes, which recognize the necessity for adequate ventilation in these enclosed spaces.

This airflow rate is specifically designed to manage pollutants and maintain a safe environment for both vehicles and occupants. By implementing 0.75 cfm of ventilation per square foot, the air exchange process effectively dilutes and decreases the concentration of hazardous emissions, promoting safety and compliance with health regulations in parking structures. Thus, this rate is the accepted standard reflecting the minimal requirements taken to ensure adequate air quality in these specific environments.
