Approximately half of all energy consumed in commercial and residential buildings is used for the HVAC systems and a significant contributor to that energy consumption is the fan power required to move air throughout the building. Air filters create resistance to that air flow and as a result, contribute to the energy consumption. However, air filters play a critical role in keeping the HVAC system clean and contribute to good IAQ within the occupied spaces. This seminar combines the lessons from recent ASHRAE-funded research with other emerging research to help building owners and operators understand the role that air filter pressure drop plays in building energy consumption.
