Presenters cover the differences in commissioning (Cx), troubleshooting, testing and balancing underfloor air distribution (UFAD) systems as compared to traditional ducted systems. Presentation content includes the idiosyncrasies associated with UFAD that engineers, contractors and operators need to be aware of so that obstacles to a successfully operating system can be avoided. The audience will learn how to obtain the IAQ, energy and cost saving benefits associated with UFAD through the use of proper Cx techniques. Real examples of successes and lessons learned will be used throughout the session including data collected to demonstrate compliance of system operation and performance. The seminar also highlights typical misunderstandings and misconceptions of UFAD operation and the resolutions developed during design, construction, and operation of UFAD systems.
