Trends in Small Rooftop Systems

A large number of buildings use small, packaged rooftop units for HVAC. This ENL will discuss several recent regulatory changes and technology advances that affect systems using this class of equipment.

After attending you will be able to:

• Summarize recent changes to minimum efficiency requirements and regulations from ASHRAE Standard 90.1 and the Department of Energy.
• Explain the various energy efficiency ratings used for small rooftop equipment (EER, SEER, and IEER).
• Understand single-zone VAV control in rooftop units equipped with either modulated or staged/cycled heat.
• Apply small rooftop units in multiple-zone VAV systems.
• Employ energy-saving control strategies, such as demand-controlled ventilation, airside economizing, fan pressure optimization, and supply air temperature reset.

Attendees will earn 1.0 AIA or GBCI/LEED Learning Units!
There is no fee for this course and lunch will be provided.
