ASHRAE publishes underfloor air distribution systems guide

ASHRAE's “UFAD Guide: Design, Construction and Operation of Underfloor Air Distribution (UFAD) Systems” incorporates updated results from laboratory and field experiments.


With use of underfloor air distribution (UFAD) systems increasing in commercial and institutional buildings in North America, ASHRAE has published a new comprehensive guide on their design, construction, and operation.

“UFAD Guide: Design, Construction and Operation of Underfloor Air Distribution (UFAD) Systems” incorporates updated results from laboratory and field experiments. Also included are simulation studies, manufacturers’ literature, design experiences from practicing engineers, and other relevant guidelines from users of UFAD. For those in the construction, building commissioning, and operations and maintenance industries, this design guide provides a wealth of information on an emerging technology, all while keeping in mind the typical flow of decision making.

The use of UFAD is increasing in North America as a solution to space conditioning concerns. The design guide provides assistance in the planning, construction and operation of UFAD systems, while carefully detailing the major differences between UFAD and more traditional forms of space conditioning.
