Overview of HVAC System Design Concepts: Underfloor Air Distribution, Chilled Beams, Dedicated Outdoor Air Terminals and Displacement Ventilation


Approved for New Jersey, New York, and Pennsylvania Continuing Education Credits-One PDH

An outline presentation of design issues related to these concepts will discuss the following:
1. Why new HVAC system design concepts need to be considered
2. Discuss the limitations of common VAV system applications, their operating costs and renovation costs.
3. LEED perquisites and requirements
4. ASHRAE Standard 62.1 (Ventilation) and Standard 55 (Thermal Comfort) compliance
5. Air distribution sound level conformance
6. For each of the new design concepts, UFAD, CB, DOAS terminals, and DV discuss:
a. Why and when to use or not to use these design concepts.
b. What differences in outdoor design conditions may be required?
c. What additional building design and construction trade coordination is required?
d. What system components are usually required?
e. What typical controls are required?
f. What differences in first and operating costs can be expected relative to standard VAV designs?
g. What construction and operating problems have been experienced?
h. What is the impact on space requirements for mechanical components?
i. What unique design issues must be addressed?
j. The advantages and disadvantages of these design concepts
