TITLE:  Energy Conservation Program for Certai n Industrial Equipment: Energy Conservation 
Standards for Commercial Heating, Air-C onditioning, and Water-Heating Equipment 
 AGENCY:  Office of Energy Efficiency and Renewable Energy, Department of Energy 
 
ACTION:  Notice of data availability and request for public comment 
 SUMMARY:  The Energy Policy and Conservation Act of 1975 (EPCA), as amended, directs the U.S. Department of Energy (DOE) to establish en ergy conservation standards for certain commercial 
and industrial equipment, including commercial h eating, air-conditioning, a nd water-heating products. 
Of particular relevance here, the statute also requires that each time the corresponding consensus 
standard--the American Society of Heating, Re frigerating and Air-Conditioning Engineers, Inc. 
(ASHRAE)/Illuminating Engineering Society of No rth America (IESNA) Standard 90.1--is amended 
by the industry, DOE must assess whether there is a need to update the uniform national energy 
conservation standards for the same equipment c overed under EPCA. ASHRAE officially released an 
amended version of this industry standard (A SHRAE 90.1-2010) on October 29, 2010, thereby 
triggering DOE's related obligations  under EPCA.  In addition, the Energy Independence and Security 
Act of 2007 (EISA 2007) amended EP CA to require DOE to review  the most recently published 
ASHRAE/IES Standard 90.1 with respect to singl e-package vertical air conditioners and single-
package vertical heat pumps in accordance with the procedures established for reviewing the energy 
conservation standards for other ASHRAE products.  As a first step in meeting these statutory 
requirements, today's notice of data availability ( NODA) discusses the results of DOE's analysis of 
the energy savings potential of amended energy  conservation standards for certain types of 
commercial equipment covered by ASHRAE Standa rd 90.1, including single-package vertical air 
conditioners and single-package vertical heat pum ps.  The energy savings potentials are based upon 
either the efficiency levels specified in the am ended industry standard (i.e., ASHRAE Standard 90.1-
2010) or more stringent levels that would result in  significant additional conservation of energy and 
are technologically feasible and economically justif ied.  DOE is publishing this NODA to:  Announce 
the results and preliminary conclusions of DOE's an alysis of potential energy savings associated with 
amended standards for this equi pment, and request public comment on this analysis, as well as the 
submission of data and othe r relevant information.
