Underfloor-Air-Distribution Design Concepts

UFAD systems save energy and deliver better occupant comfort and indoor-air quality for certain applications

Although the number of applications for underfloor-air-distribution (UFAD) systems has increased over the years, the basic design concept for UFAD has not changed. UFAD systems utilize the space under an access floor as a supply-air plenum, taking advantage of thermal stratification to reduce energy use.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends that an occupied zone have a temperature of 73 to 77°F, a relative humidity of 25
