The Department of Energy (DOE) has determined that its adoption of amended energy conservation standards for commercial standard size packaged terminal air conditioners (PTACs) and packaged terminal heat pumps (PTHPs), at efficiency levels more stringent than those in American Society of Heating, Refrigerating, and Air- Conditioning Engineers (ASHRAE)/Illuminating Engineering Society of North America (IESNA) Standard 90.1-1999, is supported by clear and convincing evidence that such standards would result in significant additional conservation of energy and are technologically feasible and economically justified. On this basis, DOE is today amending the existing energy conservation standards for these types of equipment. In addition, DOE has determined that its adoption of amended energy conservation standards more stringent than the efficiency levels specified by ASHRAE Standard 90.1-1999 for non-standard size PTACs and PTHPs is not supported by clear and convincing evidence, thus, DOE is adopting the efficiency levels in ASHRAE Standard 90.1-1999 for non- standard size PTACs and PTHPs in today's final rule.

Department of Energy 10 CFR Part 431 [Docket Number: EERE-2007-BT-STD-0012] RIN 1904-AB44 AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy. ACTION: Final rule. SUMMARY: The Department of Energy (DOE) has determined that its adoption of amended energy conservation standards for commercial standard size packaged terminal air conditioners (PTACs) and packaged terminal heat pumps (PTHPs), at efficiency levels more stringent than those in American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE)/Illuminating Engineering Society of North America (IESNA) Standard 90.1-1999, is supported by clear and convincing evidence that such standards would result in significant additional conservation of energy and are technologically feasible and economically justified. On this basis, DOE is today amending the existing energy conservation standards for these types of equipment. In addition, DOE has determined that its adoption of amended energy conservation standards more stringent than the efficiency levels specified by ASHRAE Standard 90.1-1999 for non-standard size PTACs and PTHPs is not supported by clear and convincing evidence, thus, DOE is adopting the efficiency levels in ASHRAE Standard 90.1-1999 for non-standard size PTACs and PTHPs in today's final rule. DATES: The effective date of this rule is November 6, 2008. The standards established in today's final rule will be applicable starting October 8, 2012 for standard size PTACs …
