This section is used for certificates and professional development credit for TDP sessions which are taught by an instructor either live or using the flash drive program. 

This module will look at the way commercial duct design creates an airflow conduit for interconnecting an air handler, VAV, and CV terminals, and room air distribution devices as a means of delivering
conditioned air to the occupants of a building. A step-by-step design process will be presented covering such aspects of duct design as zoning, load determination, layout, sizing, and determining static
pressure losses for system fan selection. After completing the module, participants will be able to manually size ductwork using either a friction chart or a duct calculator.

The fundamentals of HVAC controls introduces the basic concepts of control and the vocabulary necessary to understand HVAC controls that are part of the design of HVAC systems. This module will take the basic elements and building blocks of HVAC controls and show how comfort control systems create the desired equipment responses for maintaining room environmental condition set points. Work sessions with answers which cover the concepts covered are provided.

This training module introduces system designers to the principles of acoustics and includes suggestions on how to address acoustic issues early in design. This module has seven sections including: acoustic terms, methods used to establish an acoustic rating both indoors and outdoors, how manufacturer sound data is generated, how to determine the acoustic design goal and how to estimate the sound at the receiver using the source-path-receiver concept.
