Presentation Abstract
Specifying Variable Frequency Drives for HVAC
Applications
EAP Course ID: BAS306
Summary: Implementing Variable Frequency Drives has proven to be an effective strategy for
reducing a facility’s energy consumption during part-load conditions, but VFD technology has
evolved over time and recent advancements and code updates have had an impact on the use
of VFDs in HVAC applications. This presentation will explore the various components that
make up an “HVAC Drive”, how they work, applications, and facilitate a discussion on best
practices for specifying VFDs.
Target Audience: Consultants, Architects, ASHRAE, BOMA, USGBC
