Displacement Ventilation is a great alternative to conventional overhead ceiling supply systems. Displacement ventilation provides design flexibility, energy savings, and the highest level of indoor air quality (IAQ). The higher supply temperature and smaller air handler/system can generate energy savings. Also, the addition of more free cooling days from bringing outside air in contributes toward energy savings. On the IAQ side, DV has a ventilation effectiveness factor of 1.2 which translates to a 20% bonus when designing for ventilation requirements per ASHRAE 62.1.
