On October 12, 2018, the Department of Energy (DOE) received a petition from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) asking DOE to initiate notice-and-comment rulemaking to develop a new, unified test procedure for residential furnaces which would replace the three currently required performance metrics (i.e., annual fuel utilization efficiency (AFUE), fan efficiency ratio (FER), and standby mode/off mode energy consumption (P<INF>W,SB</INF> and P<INF>W,OFF</INF>)) with a single new metric (AFUE2). As the petition acknowledges, a combined metric would necessitate a translation of the existing energy conservation standards applicable to residential furnaces using an appropriate crosswalk. Through this announcement, DOE seeks comment on the petition, as well as any data or information that could be used in DOE's determination whether to proceed with the petition.
