The U.S. Department of Energy (DOE) has published and is taking comments on a petition from PHCC coalition partner; the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) asking DOE to develop a new, unified test procedure for residential furnaces which would replace the three currently required performance metrics of annual fuel utilization efficiency (AFUE), fan efficiency ratio, and standby mode/off mode energy consumption with a single new metric AFUE2.
The current methodology requires each of the three metrics to be reviewed over a six- to seven-year cycle. Unfortunately, these cycles do not happen on the same date or even the same year resulting in frequent redesigns of equipment. Combining the metrics into a single AFUE2 would reduce design and testing costs, marketing costs, and provide more stability in the product. PHCC is considering the information and intends to file comments prior to the mid-January deadline.
