TITLE:  Energy Conservation Program for Certai n Industrial Equipment: Energy Conservation 
Standards and Test Procedures for Commercial Heating, Air-Conditioning, and Water-Heating 
Equipment  AGENCY:  Office of Energy Efficiency and Renewable Energy (OEERE), Department of Energy 
(DOE) 
 ACTION:  Final rule  SUMMARY:  The U.S. Department of Energy (DOE ) is amending its energy conservation standards 
for small, large, and very large water-cooled and evaporative-cooled commercial package air 
conditioners, and variable refrige rant flow (VRF) water-source heat pumps less than 17,000 Btu/h. 
DOE is adopting new energy conservation standard s for computer room air conditioners and VRF 
water-source heat pumps with a cooling capacity at or greater than 135,000 Btu/h and less than 
760,000 Btu/h. Pursuant to the Energy Policy a nd Conservation Act of 1975 (EPCA), as amended, 
DOE must assess whether the uniform national sta ndards for these covered equipment need to be 
updated each time the corresponding industry standard --the American National Standards Institute 
(ANSI)/American Society of Heating, Re frigerating, and Air-Conditioning Engineers 
(ASHRAE)/Illuminating Engineering Society of North America (IESNA) Standard 90.1 (ASHRAE 
Standard 90.1)--is amended, which most recently occurred on 29 October 2010. The levels DOE is 
adopting are the same as the efficiency levels sp ecified in ASHRAE Standard 90.1-2010. DOE has 
determined that the ASHRAE Standard 90.1-2010 e fficiency levels for the equipment types listed 
above are more stringent than existing Federal energy conservation standards and will result in 
economic and energy savings compared existing en ergy conservation standards. Furthermore, DOE 
has concluded that clear and convincing evidence does not exist, as would justify more-stringent 
standard levels than the efficiency levels in AS HRAE Standard 90.1-2010 for any of the equipment 
classes. DOE is also updating the current Federal t est procedures or, for certain equipment, adopting 
new test procedures to incorporate by reference the mo st current versions of the relevant industry test 
procedures specified in ASHRAE Standard 90.1-2010.  Furthermore, DOE is adopting additional test 
procedure provisions to include with modifica tion certain instructions from Air-Conditioning, 
Heating, and Refrigeration Institute  (AHRI) operations manuals in that organization's test procedures 
that would clarify the application of the DOE test procedures and harmonize DOE testing with the 
testing performed by industry.

  DATES: This rule is effective 16 July 2012. 
Compliance Dates:  See Table 1 of section II.C of the SUPPLEMENTARY INFORMATION section of this final rule for the compliance dates associ ated with the new/amended test procedures, the 
new/amended energy conservation standards, and the representation requirements by equipment type. 
The incorporation by reference of certain publications  listed in this rule was approved by the Director 
of the Federal Register on 16 July 2012.
