Underfloor air distribution (UFAD) turns air supply upside down, allowing a floor plenum to deliver conditioned air to the space via floor diffusers in the raised floor system. The floor plenum typically consists of pedestals and removable floor panels that can be rapidly reconfigured. The space is divided into two zones: an occupied zone extending from the floor to head level, and the unoccupied zone extending from the top of the occupied zone to the ceiling. The systems are designed to condition the lower occupied zone only and the temperature conditions in the upper zone are allowed to float above normal comfort ranges. The fact that conditioned air is delivered at floor level does provide energy savings while improving comfort and indoor air quality.
While this strategy is most effective in new construction, it also can work in major retrofits. Thoughtful design is the key to successful application. This 3-hour course discusses how the UFAD system differs from conventional HVAC design and reviews several key design issues pertinent to UFAD design.
This course is aimed at mechanical and HVAC engineers, architects, building designers, contractors, civil estimators, energy auditors, and facility managers. No specific prerequisite training or experience is required.
Learning Objectives
Upon completion of this course, participants will be able to:
- Differentiate between conventional overhead (OH) and underfloor air distribution (UFAD) systems.
- Distinguish between displacement ventilation and hybrid UFAD systems.
- Explain comfort and productivity issues associated with UFAD systems.
- Describe energy savings and indoor air quality improvements associated with UFAD systems.
- Differentiate between perimeter and interior zones.
- Explain design approaches and control strategies for UFAD systems.
- Identify access-floor system design and construction issues.
- Describe economic, condensation, dirt, and fire-protection issues associated with UFAD systems.
- Explain the sustainability aspects of UFAD and how UFAD systems can contribute to energy-efficiency measures applicable to LEED certification.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. PDH credits are not awarded until the course is completed and quiz is passed.
