Pursuant to Part C of Title III of the Energy Policy and Conservation Act (EPCA), the Department of Energy (DOE) promulgates a rule prescribing test procedures to rate the energy efficiency of warm air furnaces. For commercial heating, air conditioning and water heating products generally, the rule prescribes definitions and procedural provisions, and incorporates from EPCA general enforcement and administrative provisions.

Certification, Compliance and Enforcement Requirements

The Department published a Final Rule on January 5, 2010, which adopts regulations to implement reporting requirements for energy conservation standards and energy use. The Final Rule also addresses other matters concerning compliance, certification and enforcement procedures. The Department published a Technical Amendment on January 28, 2010 that corrects cross-referencing errors in the final rule.
