Abstract: Underfloor air distribution (UFAD) systems have received attention in recent years due to a number of potential advantages over conventional overhead (OH) systems. These potential advantages include increased layout flexibility, improved indoor air quality and thermal comfort, and energy savings. In particular, energy performance advantages have been difficult to evaluate analytically due to the lack of simulation tools that accurately model the complex heat transfer processes of stratification in the room and thermal decay" (supply air temperature gain) in the underfloor plenum.
