As a result of this course you will be able to:
• Explain the RTU related requirements of the IECC.
• Select the appropriate RTU accessories to maximize performance and efficiency.
• Describe technologies such as economizers, demand controlled ventilation and energy recovery ventilation.
• Discuss the newest energy saving RTU options of multi-speed fan controls.

Who should attend?
HVAC system designers, engineers and contractors, energy efficiency specialists, facility managers, HVAC equipment manufacturer's representatives, facility engineers and anyone interested in learning more about commercial rooftop unit control strategies.

POP QUIZ
Test your knowledge of RTUs

Packaged rooftop units are used to easily and effectively heat and cool more than 50 percent of all commercial buildings in the U.S. The question is: How can we make these units more efficient? A recent U.S. Department of Energy study explored this question and the solution is summarized in three words; advanced rooftop control. Join us to explore the DOE’s recent findings, as well as the options available to save a significant amount of energy currently wasted by RTUs.

In the past 10 years, the average gas efficiency of RTUs has moved from 80 percent to just 82 percent and the cooling efficiency of the refrigeration circuits has improved slightly. Join us to learn how to improve the efficiency of existing and new RTUs.
