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.

• 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.

The advantages of access flooring and underfloor service distribution are beneficial to a wide range of building applications - from office to educational, mission critical, casinos and beyond. Just like the buildings themselves, the spaces within them have varied and specific requirements, both functionally and aesthetically. As with conventional flooring, the access floor finish options are limitless.
