Conservation Standard 

Notice of Proposed 

Rulemaking 

The Energy Policy and 

Conservation Act (EPCA), as 

amended, provides the 

Department of Energy (DOE) the 

authority to establish energy 

conservation standards for certain 

commercial equipment covered by 

the American Society of Heating, 

Refrigerating, and Air-Conditioning 

Engineers (ASHRAE) and the 

Illuminating Engineering Society of 

North America (IESNA) Standard 

90.1, including packaged terminal 

air conditioners (PTACs) and 

packaged terminal heat pumps 

(PTHPs). (42 U.S.C. 6313(a)(6)

(A)) Section 342(a)(6)(A) provides 

that DOE may prescribe a standard 

more stringent than the level in 

ASHRAE/IESNA Standard 90.1, 

after ASHRAE amends the energy 

conservation standards found in 

ASHRAE/IESNA Standard 90.1, if 

DOE can demonstrate "by clear 

and convincing evidence," that 

such a more stringent standard 

"would result in significant 

additional conservation of energy 

and is technologically feasible and 

economically justified." (42 U.S.C. 

6313(a)(6)(A)(II) At this time, 

DOE is proposing to amend the 

energy conservation standards for 

PTACs and PTHPs by raising the 

efficiency levels for this equipment

to the levels above the efficiency 

levels specified by ASHRAE/IESNA 

Standard 90.1-1999 in accordance 

with these criteria and further 

described in the notice of proposed 

rulemaking (NOPR). The proposed 

standards would apply to all 

covered PTACs and PTHPs 

manufactured on or after the date 

four years after publication of the 

final rule in the Federal Register. 

(42 U.S.C. 6313(a)(6)(D)) 

The NOPR is the first stage of the 

overall standards rulemaking 

process for PTACs and PTHPs and 

will be followed by a Final Rule. At 

the NOPR stage, DOE presents the 

proposed standard levels and all 

the rulemaking analyses, including 

the engineering analysis, the lifecycle cost analysis, the national 

impact analysis, the environmental 

impact analysis, the utility impact 

analysis, and the regulatory impact 

analysis. Stakeholders are invited 

to review the NOPR documents and 

the analytical tools, attend the 

public meetings, and submit 

comments on the analysis and 

proposed standard levels. 

DOE's comment period for the 

PTAC and PTHP NOPR stage of the 

rulemaking analysis is open until 

12:00 am EDT on June 7, 2008.
