UnderFloor Air Distribution (UFAD)

Elie Tawil, P.E., LEED AP

UFAD systems have significant potential advantages compared with traditional VAV systems. Rarely has there been a space conditioning technology that promises the combined benefits of improved thermal comfort, energy efficiency, and productivity and health improvement. While this technology has seen significant adoption in other countries, its use in the United States has only been notable since 1995.

UFAD technology, like all nascent technologies, is being advanced both in theory and practice by researchers, designers, manufacturers, and “early adopter” owners who are working to bring the design, operation, and costs to the point where it can be more easily and reliably applied. UFAD technology may someday displace overhead VAV as the “system of choice” for space conditioning. While the use of UFAD systems in particular is becoming more common in the private commercial sector; the overall potential for UFAD in federal facilities may be limited by low churn that reduces life-cycle cost benefits.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
