Trends In Small Rooftop Systems

APP-CMC061-EN

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.

  • 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.
