School uses DV in underground athletic facility

For the subgrade athletic center at Sidwell Friends School, a K-12 school on 15 acres in Washington, D.C., displacement ventilation (DV) was ideal for the 23,000-sq-ft, four-court gymnasium, which is equipped with retractable bleacher seating for 600. In this enclosed, high-ceilinged space, airborne contaminants consist mainly of carbon dioxide and odor from athletes and spectators.

When, where to use displacement ventilation

Displacement ventilation can be used instead of mixed-flow ventilation in HVAC systems. To evaluate its suitability, consider IAQ, comfort, energy consumption, and cost.
