What is UFAD?
Underfloor air distribution systems are a general class of air distribution systems that deliver air through diffusers in the raised access floor, with the intent of maintaining comfort and indoor air quality levels only in the occupied lower portion of space.
Need for Air Tightness
• UFAD Plenum typically at 0.05-0.10 in. wg (12-25 Pa)
• UFAD systems provide ~ 1.0 cfm/ft2 floor area
• Air Leakage affects comfort, energy, safety, security
• Goal is < 10% air leakage at design s.p.
