Overview
This project used a Wells–Riley model to compare outdoor-air ventilation and portable-air-cleaner capacity for a gym or sports-center zone. For a 150 m³, 50 m² case with one-hour occupancy, the analysis tested combinations intended to keep the event reproduction number below 0.5. It showed that conventional per-person ventilation ranges may be insufficient in high-activity scenarios and that higher clean-air-delivery rates can offset some outdoor-air demand. In the most demanding activity category studied, the model indicated up to a 25 percent reduction in required outdoor air. These results are scenario-based, not universal design values.
