Recent and Ongoing Activities

DOE has published a Federal Register notice announcing the availability of the preliminary analysis it has conducted for purposes of evaluating the need for amended energy conservation standards for non-weatherized oil-fired furnaces (NWOFs), mobile home oil-fired furnaces (MHOFs), weatherized gas furnaces (WGFs), weatherized oil-fired furnaces (WOFs), and electric furnaces (EFs). The analysis is set forth in the Department’s accompanying preliminary technical support document (TSD) for this rulemaking. DOE will hold a public meeting via webinar to discuss and receive comment on the preliminary analysis. The meeting will cover the analytical framework, models, and tools used to evaluate potential standards; the results of preliminary analyses performed by DOE; the potential standard levels derived from these analyses (if DOE determines that proposed amendments are necessary); and other relevant issues. In addition, DOE encourages written comments on these subjects.
