Duct Thermal Performance

COURSE NO: M02-007
Duct Thermal Performance
Course Highlights

This online engineering PDH course describes duct thermal performance as evaluated in this report which focused on large commercial buildings.  The course discusses the effects of duct deficiencies, duct performance principles such as air leakage, fan performance and heat transfer.  In addition the student will gain an understanding of the California Title 24 Duct Systems Compliance Path.


Despite the potential for significant energy savings by reducing duct leakage or other thermal losses from duct systems in large commercial buildings, California Title 24 has no provisions to credit energy-efficient duct systems in these buildings. The overall goal of the Efficient Distribution Systems (EDS) project within the PIER High Performance Commercial Building Systems Program is to bridge the gaps in current duct thermal performance modeling capabilities, and to expand our understanding of duct thermal performance in California large commercial buildings.


This 2 PDH online course is applicable to mechanical engineers who perform HVAC system designs and wish to understand more about how to reduce energy by reducing duct leakage and other thermal losses from duct systems in buildings.
