  NOTIFICATION  
Addendum 
The following communication, dated 23 July 2015, is being circulated at the request of the 
delegation of the United States of America.

 TITLE: Energy Conservation Program for Certain 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, Department of Energy 
ACTION: Final rule 
SUMMARY: The U.S. Department of Energy (DOE) is amending its energy conservation standards 
for small three-phase commercial air-cooled air conditioners (single package only) and heat pumps (single package and split system) less than 65,000 Btu/h; water-source heat pumps; and 
commercial oil-fired storage water heaters. Pursuant to the Energy Policy and Conservation Act of 
1975 (EPCA), as amended, DOE must assess whethe r the uniform national standards for these 
covered equipment need to be updated each time the corresponding industry standard--the American National Standards Institute (ANSI)/American Society of Heating, Refrigerating, 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 9 October 
2013. Under EPCA, DOE may only adopt more stringent standards if there is clear and convincing 
evidence showing that more stringent amended standards would be technologically feasible and 
economically justified, and would save a significant additional amount of energy. The levels DOE is adopting are the same as the efficiency levels specified in ASHRAE Standard 90.1-2013. DOE has 
determined that the ASHRAE Standard 90.1-2013 efficiency levels for the equipment types listed 
above are more stringent than existing Federal en ergy conservation standards and will result in 
economic and energy savings compared existing energy conservation standards. Furthermore, 
DOE has concluded that clear and convincing evidence does not exist that would justify 
more-stringent standard levels than the efficiency levels in ASHRAE Standard 90.1-2013 for any of 
the equipment classes. DOE has also determined that the standards for small three-phase commercial air-cooled air conditioners (split system) do not need to be amended. DOE is also 
updating the current Federal test procedure for commercial warm-air furnaces to incorporate by 
reference the most current version of the American National Standards Institute (ANSI) Z21.47, Gas-fired central furnaces, specified in ASHRAE St andard 90.1, and the most current version of 
ASHRAE 103, Method of Testing for Annual Fuel Ut ilization Efficiency of Residential Central 
Furnaces and Boilers. 
DATES: The effective date of this rule is 15 September 2015. G/TBT/N/USA/952/Add.1

  Compliance with the amended standards established for water-source heat pumps and commercial 
oil-fired storage water heaters in this final rule is required on and after 9 October 2015. Compliance with the amended standards established for small three-phase commercial air-cooled air conditioners (single package only) and heat pumps (single package and split system) less than 
65,000 Btu/h in this final rule is required on and after 1 January 2017. The incorporation by 
reference of certain publications listed in this rule was approved by the Director of the Federal 
Register as of 15 September 2015.
