Session Synopsis - "Residential Furnace and Air Handler Fans: Performance-based Program Opportunities"

Harvey Sachs, ACEEE

Thursday, August 22
2:00 PM - 4:00 PM

Residential forced air system air handlers vary greatly in efficiency. Within a furnace capacity class, rated annual electricity use may vary by a six-fold or more. The difference between the average "outstanding" unit and the bulk of the market is roughly equivalent to the annual energy use of a 2001 refrigerator. Unfortunately, the differences are not brought out well in standards or rating methods. In part, this reflects regional needs. ACEEE has developed performance-based metrics for northern climates, where fan size (and electricity use) can be correlated with furnace capacity. However, these methods are not directly applicable in hot regions where models have larger fans (that use more energy). The goal of the session is to explore potential program needs for both cool and hot climates. We will briefly summarize work to date on technical parameters and program designs for cold climates, and the additional challenges for warm regions. We'll then discuss needed next steps for effective programs in both cold and warm climates.
